    可我没有安装光盘,也没有那么大的U盘做启动盘,我是用WinPE安装的系统。重复安装了多少次,换了几个盘都不行。

    但还是出现相同的错误。

    朋友提醒可能是没有激活分区,用diskgenius看了一下,果然没有激活,怎么会发生这种问题呢,之前一直没遇到这种情况。
    但激活之后错误依然。

    最后想到应该是BIOS的问题,把BIOS Load Default了一下,

    Lesson 1 Visiting a Friend 1-2

    Christina is on a two week vocation.

    This is the first vocation she has had for a long time.

    The last vocation she took was more than two years ago.

    Now she is visiting a friend in San Francisco.

    Her friend and her husband are living near the center of the city.

    He works for a start-up company in Silicon Valley.

    While he is working, she works part-time at a department store.

     

    -How long has it been since her last vocation? –It’s been more than 2 years.

    -What kind of company does her friend’s husband work for? –A start-up company.

     

    Christina hasn’t seen her friend for a longtime.

    The last time they saw each other was three years ago.

    At that time, they were both working at a department store.

    Then Christina quitted her job and started her own business.

    She designs women’s clothing.

    She has two employees now and her company is slowly growing.

     

    -How long has it been since Christina last saw her friend? –It has been 3 years.

    -Where were Christina and her friend working before she started her own business? –They were working at a department store.

    -How long has it been since Christina started her own business? –It’s been 3 years.

     

    Christina has come to San Francisco by herself.

    Her husband didn’t come, because he has to work.

    He tried to start a company two years ago, but it didn’t work out.

    His company failed after only a few months.

    So now he is working at another company and saving money.

    Once he saves enough money, he plans to start another company. He doesn’t want to give up.

     

    -Why hasn’t Christina’s husband come with her? –He has to work.

    -Why is Christina’s husband saving money? –He wants to start a new company.

     

    This is the second time Christina has been to San Francisco.

    The first time was when she was a high school student.

    That was more than ten years ago.

    During that trip, she was only in San Francisco for a few days.

    After that, she went to Los Angeles and New York.

    This time she and her friend plan to relax and have fun.

     

    -How many times has Christina been to San Francisco? –She has been to San Francisco twice.

    -How long did she stay in San Francisco on her first trip? –A few days.

    Lesson2

    Christina arrived two days ago, the day before yesterday.

    Her friend met her at the airport, and drove her to her apartment.

    Her apartment is just north of the airport, about 20 minutes from San Francisco.

    It’s a small apartment, but it’s on a hill, and it has a great view.

    Yesterday they went downtown, and rode the cable cars.

    Christina was surprised by how steep the hills are.

    Then they walked along the ocean, and ate lunch at a sea food restaurant.

    From the restaurant, they could see the Golden Gate Bridge.

     

    -How long has she been here? –For two days.

     

    Tomorrow they are planning to drive to Yosemite National Park.

    By car, it’s about four hours away.

    Christina has never been there before, so she is excited.

    She has heard that the park is very beautiful.

    Her friend has been to Yosemite several times.

    She says it’s one of the most beautiful places in the world.

    Christina just hopes that her friend is a good driver.

     

    -How many times has she been to the Yosemite? –Never.

    Vocabulary

    Lesson 3 Pains and Sickness

    Headaches can be very painful, and can last for a long time.

    If you have a headache, your head hurts.

    A sprained ankle can be so painful that you can’t walk.

    Someone with a sprained ankle may need to use crutches to walk.

    If you have a sore throat, it may be painful to swallow.

    A sore throat can be caused by viruses or bacteria.

    A burn is an injury to the skin caused by fire or heat.

    If you get to close to a fire, you will be burned.

    An earache is a sharp, dull or burning pain in the ear.

    Common causes of an earache include an infection, a changing air pressure, or water in the ear.

    Lesson 4 Landforms

    Mountains are land forms higher than 2000 feet or about 600 meters above sea level.

    Hills are like mountains but not as tall.

    Mountains are formed by forces deep within the Earth, and are made of different types of rocks.

    Rivers are streams of water that usually begin in mountains and flow into the sea.

    Many early cities were built alongside rivers.

    Most of the world’s water is in the oceans, which are large bodies of salt water.

    The oceans are also an important source of oxygen.

    Deserts are areas of land that receive little or no rainfall.

    The amount of rainfall in some deserts is so low that only a few plants can survive.

    A valley is a low relatively flat area between hills or mountains, often with a river running through it.

    Some valleys are formed by flowing water, and others are formed by glaciers.

     

    The Pacific Ocean is the largest and deepest ocean, covering more area than all the continents put together.

    Desert temperatures can range from cold at night to very hot during the daytime, often above 120 degrees F.

    Lesson 5 Eating Out

    M: Have you eaten yet?

    W: No, I haven’t, and I’m hungry.

    M: Me too. Let’s go out for dinner.

    W: Where to?

    M: What about Joe’s Italian?

    W: How many times have you eaten there?

    M: I eat there a lot. It’s one of my favorite places.

     

    -Why is she hungry? –She hasn’t eaten yet.

     

    W: I went there two weeks ago, and the service was terrible.

    M: Really? Then let’s go someplace else. 

     

    -Why doesn’t she want to go to Joe’s Italian? –She went there two weeks ago and the service was terrible.

     

    M: What do you suggest?

    W: How about the Royal Indian? It’s not far from here.

    M: I’ve never heard of it. Is it good?

    W: Yes, I’ve been there several times, and I’ve never been disappointed.

     

    -What’s one reason she suggests Royal Indian? –It’s not far away.

    -Has she been to the Royal Indian before? –Yes, she has.

     

    M: OK, let’s try it. I haven’t eaten Indian food for a long time.

    W: You won’t be disappointed, and the prices are reasonable.

    M: Ah, so you mean I’m going to pay.

    W: Well, that would certainly be nice.

     

    -How expensive is the restaurant? –It’s reasonably priced.

     

    M: What about reservations?

    W: If we get there early enough, we won’t need them.

    M: I hope you are right.

    W: Don’t worry, if we have to wait, I’ll pay the bill.

     

    -What would happen if they don’t get there early enough? –They may have to wait.

    When she went there two weeks ago, the service was awful.

    She has been there several times.

    Lesson 1 A Trip to Yosemite Park 1-2

    Today Christina and her friend are enjoying themselves.

    This morning they got up very early and drove out of San Francisco.

    They crossed the Bay Bridge before the early morning commute and drove south.

    Because it was so early, there were almost no cars.

     

    -How heavy was the traffic? –There were almost no cars.

     

    After driving for an hour and a half, they stopped and had breakfast.

    They ordered pancakes and coffee.

    They also had some fresh fruit.

    When they finished eating, it was seven o’clock.

    Then they got back into the car, and drove south.

    Christina wanted to listen to music, so they turned on the radio.

    An hour later, they stopped for gas.

    They noticed that there was also a charging station for electric cars.

     

    -How did they order for breakfast? –They ordered pancakes and coffee.

    -What did they do after they finished eating? –They got back into the car and drove south.

     

    It’s now 1:15 (one fifteen), and they are in Yosemite Park.

    They have been there for two hours, since 11:15(eleven fifteen).

    They are looking at Yosemite falls, which is the highest waterfall in the park.

    The water drops a total of 740 meters from the top of the upper fall to the base of the lower fall.

     

     -When did they arrive at the park? –They got there at 11:15.

     

    In another fifteen minutes, they planned to eat lunch at a magnificent old hotel in the park.

    It was built in 1927 and has a great view.

    They wanted to stay there but they couldn’t get reservations.

    To get a room at that hotel, you usually need to make reservations several months in advance.

     

    -When do you need to make reservations? –You need to make reservations several months in advance.

    -Why couldn’t they get reservations? –They didn’t reserve early enough.

     

    They planned to stay in the park until around four o’clock.

    By then, they will have been in the park for nearly five hours.

    Then they will get back into the car and drive back to San Francisco.

    They plan to eat dinner somewhere along the way.

    If the traffic isn’t too bad, they should be back in San Francisco by ten o’clock.

     

    -When do they expect to be back in San Francisco? –They expect to be back by 10 o’clock.

    -How long would they have been in the park if they leave as scheduled? –For nearly 5 hours.

     

    Early tomorrow morning, they are going to cross the Golden Gate Bridge and go north along the coast.

    From some places you can look out on the ocean and see whales and other sea life.

    Christina has never seen a whale before, so she is looking forward to it.

    And tomorrow night they have something special planned.

    They are going to watch a baseball game.

    Christina has never seen a baseball game, but she has heard that it is very popular in the US.

    And the San Francisco baseball team is one of the best.

     

    -What does she hope to see from the coast? –She hopes to see whales.

    -What are they going to do tomorrow morning? –They are going to cross the Golden Gate Bridge.

    Vocabulary

    Lesson 3 Science

    A force is a push or a pull on an object.

    A force changes the motion of a moving object.

    A force can be strong or weak and it always has a direction.

    The Earth is a planet that goes around the sun in a circular orbit.

    The speed of its motion doesn’t change, but the direction of its motion does.

    The Earth has a layer of gas above its surface which helps to support life.

    Atoms are the building blocks of matter.

    At the center of an atom is its nucleus which has a positive electric charge.

    Outside the nucleus are electrons which have a negative charge.

    Asteroids and comets are objects that obey our sun, but are smaller than planets.

    Asteroids that pass close to the Earth are called near-earth objects.

    The layer of gases just above the Earth’s surface is our atmosphere.

    The atmosphere is made of gases such as oxygen and nitrogen.

    Without an atmosphere there would be no life on Earth.

     

    If they collide with Earth they could cause an extinction event.

    A force can increase or decrease the speed of an object, and it can change the direction of motion.

    The electric force between the nucleus and the electrons holds the atom together.

     

    Lesson 4 Geometry

    The two lines on the left intersect each other at a right angle which is 90 degrees.

    The two lines on the right are parallel which means they never cross.

    The adjacent sides of a rectangle are perpendicular which means they meet a 90-degree angle.

    The opposite sides of a rectangle are equal and parallel which means they never cross.

    The area of a rectangle is the length times the width.

    A circle is a two dimensional figure with a radius and a circumference which is the distance around the circle.

    The area of a circle is Pi R squared, where R is the radius and Pi is the ratio of the circle circumference to its diameter.

    A sphere is a three dimensional figure with a radius and a volume which is four thirds Pi R cubed.

    All points on the surface of a sphere are equidistant from its center.

    A right triangle is a two dimensional figure with three side, two of which are perpendicular.

    To find its area, multiply the length of the two perpendicular sides a and b and divide by 2, A equals 1 half ab.

     

    A rectangle is a 2 dimensional figure with 4 sides.

    Lesson 5 Dinner Conversation

    M: Have you finished eating yet?

    W: No, I haven’t. Why are you in such a hurry?

    M: I’m sorry, but you are such a slow eater.

    W: A slow eater? Well, I try to enjoy my food. You just eat and swallow.

    I don’t see how you can even taste it.

     

    M: OK, I’m sorry. Do you mind if I get another glass of wine?

    W: No, go ahead. I don’t want you to sit there putting pressure on me.

    I thought we were going to have a relaxing evening.

     

    -What does she allow him to do? –She allows him to get another glass of wine. A relaxing evening is the opposite of a high-pressure evening.

     

    M: Yes, you are right. I’d like to relax, but I have a lot on my mind.

    W: Work related?

    M: Yes, it is. I’ve been getting some strange emails from my boss.

    He wants me to cut down on my expenses. Maybe he wants to fire me.

     

    His boss wants him to spend less.

    -What is he afraid of? –He may lose his job.

     

    W: Is business bad?

    M: Yes, it is. But I don’t want to talk about it.

    W: OK, but I’m a good listener. You can tell me if you’d like to.

     

    -What doesn’t he want to talk about? –He doesn’t want to talk about his business.

     

    M: Thanks. Maybe some other time.

    I’ll try to stop thinking about it until when it’s tomorrow.

    W: Good idea. You need to take a break from work. Your healthy is important, and so am I.

    M: Yes, you are. I don’t know what I would do without you.

     

    To deal with something means to do something about it.

    Lesson 3 Dental Problems

    A dental cavity is a hole in a tooth.

    A cavity is caused by bacteria in the mouth.

    Brushing your teeth frequently and regularly can help prevent cavities.

    A crack tooth can be caused by biting down on something hard.

    Dentists treat a crack tooth by covering it with a crown.

    A dental X-Ray is a picture of your teeth and gums.

    An X-Ray shows what can’t be seen on the surface of the teeth and gums.

    Braces are used by dentists to strengthen teeth over a period of years.

    Through braces are usually for children, they can also be used for adults with crooked teeth.

    To exact a tooth means to remove it from the mouth.

    Dentists have to pull hard to exact a tooth.

     

    Braces are used on people with crooked teeth or after an injury.

    Biting down on something hard can be very painful.

    Dentist often inject something into the gum to block the pain during the extraction process.

     

    Lesson 4 Internal Organs

    The heart pumps blood to all parts of the body through a system of arteries and veins.

    It’s located in the chest, between the lungs, and beats about once per second.

    The kidneys remove waste and toxins from the blood.

    They are bean-shaped organs, and are about 10 centimeters long and 6 centimeters wide.

    The lungs exchange oxygen from the air, with carbon dioxide from the blood.

    They expand when inhaling air, and contract when exhaling air.

    The stomach is blow the heart, and is part of the digestive system.

    Lesson 2 The World’s Population

    The world’s population is growing.

    There are now over 7 billion people in the world.

    During the 20th century, the population grows from 1.65 billion to 6 billion.

    It’s now growing at a rate of around 1.1% per year.

    That mean it increases about 18 million per year.

    By 2024, the population has expected to be around 8 billion people.

     

    -How fast is the world’s population growing? –The growth rate is about 1.1% per year.

    -What was the population at the end of the 20th century? –around 6 billion people.

     

    The growth rate used to be higher.

    In the late 1960s, the rate of growth was about 2%.

    Since then, the growth rate has declined.

    It is estimated that the growth rate will be less than 1% by 2020.

    By the year 2050, the growth rate should be even less.

     

    -What has happened to the growth rate? –It has declined since the 1960s.

    It is estimated that the growth rate should be even less.

     

    Even with the declining growth rate, the population will continue to grow.

    But it will grow at a slower rate.

    In the past 15 years the world’s population has more than doubled.

    It has doubled from around 3 billion in 1960 to more than 7 billion in 2011.

     

    -What has more than doubled in the past 15 years? –the world’s population.

     

    The rate of growth varies by country.

    The growth rate in India is more than twice that of China.

    And the growth rate in Nigeria, which is in Africa, is more than twice India’s growth rate.

    Russia, on the other hand, has had a negative growth rate in some years.

    When a country has a negative growth rate, its population is decreasing.

     

    -How do the growth rates of India and China compare? –India’s growth rate is higher.

    Lesson 1 Extinction Events 1-2

    The earth was formed by about 4.6 billion years ago.

    The first life appeared about a billion years later.

    The first plaints didn’t appear until around 2 billion years ago.

    Until about 580 million years ago, life forms were small and microscopic.

    Since that time, life has evolved into many different types or species.

    However, scientists estimate that more than 99% of them are now extinct.

     

    -When did the first plant appear on earth? –about 2 billion years ago.

     

    There have been several extinction events in the history of the Earth.

    In an extinction event, many life forms, or species of life, die out.

    The causes of mass extinction events are unsolved mysteries.

    These events are not predictable, and can happen at any time.

    Scientists think that some of them were started by asteroid impacts or volcanic eruptions.

    Events like this can change the global conditions that life depends on.

     

    -What happens in an extinction event? –Many species of life become extinct.

     

    One major extinction event happened about 66 million years ago.

    That event may have been started by a large asteroid that hit the Earth.

    As a result, the dinosaurs and about half of all species on the planet, died out.

    When the asteroid hit the Earth, it started a chain of events.

    A chain of events is a series of events linked together, like a chain.

     

    -What may have caused the extinction of the dinosaurs? –An asteroid hit the earth and started a chain of events.

     

    This particular chain of events happened over a period of months and years.

    When the asteroid hit the Earth, it caused a huge cloud of dust to enter the atmosphere.

    This cloud of dust blocked the sun and darkened the Earth for many months.

    Without enough sunlight, plants and plant-eating animals quickly died.

    With the deaths of so many plants and animals, the food chain collapsed

    This led to the deaths of many more species.

     

    -What caused the food chain to collapse? –The deaths of many plants and plant-eating animals.

     

    Mass extinction events have played an important part in the evolution of life.

    In fact, some extinction events have helps to accelerate evolution.

    For example, some mammals lived through the age of the dinosaurs, but they couldn’t compete.

    When the dinosaurs were removed, the mammals were able to compete more successfully.

    Once they could compete, mammals evolved to higher state.

    Without extinction events, perhaps we wouldn’t be here today.

     

    -What may accelerate the evolution of mammals? –the extinction of dinosaurs.

    Mammals couldn’t compete successfully with the dinosaurs, so their evolution was blocked.

     

    Scientists estimated that there had been at least 5 mass extinctions in the last 540 million years.

    They also believed that we have entered a new extinction event.

    Species are becoming extinct at a much faster rate than before.

    Instead of the asteroid or volcanic eruptions, the current event is a result of human activities.

    Human activities, for example, have led to global warming.

     

    -What is causing the current mass extinction event? –human activities.

    -What do scientists believe has already started? –a new extinction event.

     

    Global warming is a result of an increasing in carbon gases in out atmosphere.

    These gases trap heat from the sun, so the Earth is getting warmer.

    As a result, sea levels are rising, and weather patterns are changing.

    In addition, we humans are destroying the habitats of many plants and animals.

    Cutting down forests, and polluting rivers destroys the habitats of many forms of life.

     

    -Why are sea levels rising? –With the rise in temperature, the polar icecaps are melting.

     

    There is no longer any doubt that this is happening.

    Species of life are disappearing at an increasing rate.

    Global temperatures are rising and weather patterns are changing.

    Scientists are warning us that fast action is necessary to save our future.

    If we don’t act, we may go the way of the dinosaurs.

     

    This new extinction event is caused by humans.

    Lesson 3 Body Systems

    The body’s circulatory system includes the heart and blood vessels.

    The heart pumps blood to all parts of the body through a network of arteries and veins.

    The digestive system breaks down and absorbs food into the body.

    It supplies the energy that the body needs for growth and repair.

    After digestion, excess food is turned into waste and eliminated from the body.

    The nervous system includes the brain, spinal cord, and nerves.

    This is your body’s control system.

    It controls your muscles and organs, including your circulatory and digestive systems.

    The respiratory system includes the nose and lungs.

    It brings air and oxygen into the body and removes carbon dioxide.

    The lungs are where oxygen enters the bloodstream and carbon dioxide is removed.

    The immune system protects the body against infections and diseases.

    Sneezing and fever are examples of how the immune system works.

    If an infection invades the body, the immune system attacks it.

     

    The nervous system regulates your heartbeat and digestion.

    For some diseases, the immune system uses white blood cells and antibodies to attack it.

    The digestive system is where food is broken down and absorbed into the body.

     

    Lesson 4 Great Discoveries

    The controlled use of fire allowed people to cook food and survive in colder climates.

    Fire provided light so that people could work and socialize for longer hours.

    With the invention of agriculture people could grow food and settle into communities.

    By growing food, people could spend less time hunting and more time for other things such as art.

    The domestication of animals allowed people to raise and use animals for food and work.

    By raising herds of animal such as sheep, humans had a regular supply of meat and clothing.

    The strength of animals such as horse and ox was used for working transportation.

    The development of tools and machines has resulted into more efficient manufacture and construction.

    With better tools and machines work can be done with fewer people at much lower cost.

    The development of science and engineering has improved many things including communications.

    With an understanding of electricity, telephones and radios allow people to communicate over long distances.

     

    Science and engineering breakthroughs are rapidly changing the way we live our lives.

    Science and engineering have changed the way we communicate with each other.

    The use of machines has reduced the number of people needed to make things.

    With the development of agriculture, people had more time for other activities.

    The ability to raise herds of animals gave human a regular supply of meat and clothing.

    This man is holding a piece of fruit in his hand.

    The piece of fruit is either an orange or an apple.

    We can’t see which it is because we can’t see inside the box.

    The probability that it is an orange is equal to the probability that it is an apple.

    It may be an apple and it may be an orange.

    It’s got to be one or the other.

    It can’t be anything else.

     

    -What’s the probability that it’s a banana? –The probability is 0%. It may be an apple but it can’t be a banana.

     

    Now let’s look at it from the man’s point of view.

    From his point of view, the probabilities are different.

    From his point of view, the probability that he has an orange is 100% or 0%.

    That’s because he knows what he has.

    For him, there is no uncertainly.

    If he has an orange, the probability is 100%.

    If he doesn’t have an orange, the probability is 0%.

    He either has it, or he doesn’t.

     

    -From our point of view, what’s the probability that it’s an orange? -50%.

     

    From our point of view, the probability that he has an orange is 50%.

    From his point of view, the probability that he has an orange is 100% or 0%.

    So the probability depends on your point of view.

     

    -What’s the probability that it’s a banana? –a 0% probability.

    The probability depends on your point of view, or how much you know.

     

    People see things from different points of view.

    This often leads to arguments between people.

    Here are some examples.

    From this man’s point of view, he is relaxing.

    He needs to relax because he has been working too hard.

    He hasn’t been getting enough sleep.

     

    -If his wife shouts at him and tells him to get up and do something…

    -he may shout back and refuse to help her.

     

    His wife sees things differently.

    She isn’t aware of how hard he has been working.

    From her point of view, he is doing nothing.

    However, she knows what needs to be done around the house.

    It isn’t fair that she had to work while he does nothing.

     

    -If he gets up and helps her… -She may not appreciate his help.

    -From the husband’s point of view, what’s he doing? –He is relaxing.

     

    When people see things from different points of view, they often come to different conclusions.

    These differences can cause real communication problems.

     

    People often argue with each other because they see things from a different point of view.

    M: How many countries are helping with the search?

    W: Right now we have search teams from 3 countries starting the search.

    M: It’s a big area to search, so can you give us an estimate about how long it will take?

    -How much of the airplane have they found? –some pieces.

     

    M1: What about the black boxes?

    M2: No, they still haven’t found the black boxes.

    M2: Perhaps they’ll never know, especially if they don’t find the black boxes.

    M1: Whatever happen to it, there is no good reason why a modern airline is allowed to disappear.

    M2: I agree with you.

    Lesson 1 Alcatraz 1-2

    Alcatraz is a small island in San Francisco Bay, 1.5 miles from San Francisco.

    Tourists can reach the island by boat from the city.

     

    -What can people see from Alcatraz? –The Golden Gate Bridge.

     

    Alcatraz has often appeared in movies, including Escape from Alcatraz, which was made in 1979.

    One reason it’s famous is because it used to be a prison, a very special prison.

    It was designed for prisoners who were causing trouble in other prisons, such as trying to escape.

    It was a maximum security prison, so escape was almost impossible.

    The waters around it are cold and only very strong swimmers can swim from the island to San Francisco.

     

    -What kind of prisoners was it designed for? –prisoners who were troublemakers.

    -Why is it famous? –It used to be a very special prison.

     

    The first group of prisoners arrived in 1934.

    There were 137 prisoners including bank rubbers and murderers.

    They came by train from another prison in the state of Kansas.

    During that trip, there was heavy security.

    The prisoners were under guard and handcuffed.

    Nobody wanted them to escape.

     

    -Where do the first group of prisoners come from? –They came from Kansas.

     

    The prison was designed to hold up to 336 prisoners.

    However, the average population was only about 270.

    Although there were several notorious inmate such as Al Capone, most of the inmates were not well known.

    Many had tried to escape from other prisons or working setter to violent.

    If a man did not behave at another prison, he could be sent to Alcatraz.

    At Alcatraz, there was just one inmate in each prison cell.

     

    -Why were prisoners usually sent to Alcatraz? –They caused trouble at other prisons.

    -A notorious inmate is one who… -is very well known.

     

    Prison life at Alcatraz was highly structured and boring.

    It was designed to teach prisoners to follow rules.

    They had four rights: food, clothing, shelter and medical care.

    Everything else was a privilege that had to be earned.

    Privileges included working, visits from family members and access to the prison library.

    There were also activities such as painting and music.

    Once a prisoner showed that he could follow the rules, he could be transferred back to another prison to finish his sentence.

     

    Alcatraz was used as a prison for 29 years.

    During that time, no prisoners escaped successfully.

    There were 14 escape attempts, involving 36 prisoners.

    23 were caught alive and 6 were shot and killed.

    2 men tried to escape twice.

    2 drowned and 5 were listed as missing and presumed drowned.

    The most violent escape attempt occurred on May 2nd 1946, when 6 prisoners tried to escape.

    That event is called the battle of the Alcatraz.

     

    -How many prisoners escaped? –none.

     

    While it was in use, Alcatraz had some of the most notorious criminals in American history, such as Al Capone.

    Al Capone was a crime boss, who built his career in Chicago.

    The prison was finally closed in 1963.

    It was closed because it was too expensive to operate.

     

    -Why was the prison finally closed? –It was too expensive to operate.

    No prisoners ever escaped from Alcatraz.

    Lesson 1 Time Distribution

    Look at these two pie graphs.

    They show how these two people spend their days, not including weekends.

    The one on the top shows how Emma divides up her days.

    She is a designer who works for a large company.

     

    -20% of the day is how much hours? -4.8 hours.

     

    As Emma’s graph shows, the biggest portion of her day is spent working.

    She works an average of 8 hours a day, which is 1/3 of her day.

    She gets an average of 6 hours of sleep, which is 25% of her day.

    That’s less sleep than Martin gets.

    According to his graph, he gets an average of 7 hours of sleep, which is about 29% of his day.

    On the other hands, Martin, who is an engineer, works more hours than Emma does.

    Martin averages 9 hours a day at work, compared to Emma’s 8.

    That’s 37.5%, compare to 33%.

    Other factors shown in the graphs include time for meals and commuting to work.

     

    -What percent of the day does Emma spend at her work? -33%.

     

    Other activities include getting dressed and household choice, such as doing laundry and paying bills.

    As you can see, for Martin, commuting is taking a large amount of his time.

    If he could reduce his commute time, he will have more time for other things.

    And it isn’t just the time.

    When the traffic is really heavy, his commute is stressful.

    It would be great if he could work from home for 1 or 2 days a week.

    His life will be more enjoyable.

     

    -In what category are things like doing the laundry or paying bills? –other.

     

    And looking at Emma’s graph, we see that she probably needs more sleep.

    Perhaps she should spend a bit less time socializing with her friends.

    On the other hand, socializing with her friends is something she really values.

    As for putting on makeup, she isn’t willing to change that.

    For her, exercising, socializing and staying beautiful help her deal with the stress of work.

    In conclusion, Emma and Martin both wish there were more hours in a day.

     

    Lesson 2 Job Satisfaction Factors

    These next graph shows how various factors compare an importance to 1500 job applicants.

    These applicants were between 20 and 25 years old.

    They were asked to list which factors were most important to a good job.

    As the graph shows, money was the most important factor for 25% of the applicants.

    However, other factors were also important.

    The second most important factor was the working environment.

     

    -According to this graph, what was the second most important factor? –a good work environment.

     

    In other words, for many, money isn’t everything.

    People want to like where they work.

    In fact, if we combine working environment and coworkers, the total is 35%.

    This is well above the 25% for salary and benefits.

    Taking together, they are more important than salary and benefits.

    Career path is also important, especially for younger applicants.

    They want to see that their job helps build the successful career.

    For older workers, this may not be as important.

    Older workers often put a higher value on the balance between life and work.

    What do you think?

     

    Which conclusion most accurately summarize this graph? –A good job needs to satisfy several needs.

    -People who want their work to be challenging are people who…-enjoy solving problems.

    The best jobs satisfy several needs, not just salary and benefits.

    A state of anarchy exists when a country has no effective government.

    In anarchy, there is nobody to make decisions and enforce the laws.

    An autocracy is the simplest form of government.

    In autocracy, the government is controlled by single individual, known as the autocrat.

    Whether or not an autocracy is successful depends on the character and ability of the leader.

    In an oligarchy, a small group of people controls the government.

    Membership of its group often depends on family connections, wealth, or military power.

    In a republic, individuals are elected to represent the citizens.

    The power of the government in a republic is limited by constitution.

    A constitution is a written document that makes the rules for a government to follow.

    This limits the power of the government.

    A constitution defines the relationship between the government and its citizens.

     

    Who make decisions and enforce the laws in an anarchy? –nobody.

    -What is a common way for oligarchy to increase their wealth? –bribery and corruption.

    Bribery and corruption are common as a way to increase the wealth of the oligarchs.

    Without a good government, decisions that need to be made, won’t be made.

    If a store runs out of things to sale, it needs to resupply its inventory.

    An investment is a purchase of an asset with the hope that its value will increase.

    A good investment will produce income, such as rental income.

    If the value of an asset falls, the investment will lose money.

     

    -If you own a house, it is… -an asset.

    To take inventory means to make a detailed list of the items that you have.

    When you sell an asset at a higher price than what you paid for it, you have made a profit.

    If you buy a house and get a loan, the amount you owe on your loan is part of your debt.

     Lesson 4 Countries and Continents

    China is the second largest country in the world by land area.

    A major issue for China’s continue extension of its deserts, which have led to dust storm each spring.

    Many of world’s most polluted cities are located there.

    South Asia is referred to as the India subcontinent.

    It’s called a subcontinent because it’s separated from the rest of Asia by mountains and seas.

    It is one of the world’s poorest regions with about 75% of the poor living in rural areas.

    Europe is the western neighbor of Asia.

    It’s separated from Asia by the Ural Mountains which extend for 1500 miles and north-south direction for the Arctic Ocean.

    The Philippines is the only country in Asia with the majority of Christians.

    The Philippines is an island nation with over 7000 islands.

    It’s located in the South China Sea.

    The country’s capital city is Manila.

    Asia is the world’s largest continent covering about 30% of the earth’s land area.

    Several island nations are also a part of Asia, including Japan.

    The world’s tallest mountains are in Asia, including MT Everest.

     

    The traditional boundary line between them is the Ural mountain range.

    As a result, the country is investing heavily to reduce air pollution.

    Lesson 5 Election & Voting

    W: Hey, have you decided how you’re going to vote?

    M: No, I haven’t. I don’t like any of the candidates.

    W: So you aren’t going to vote?

    M: Hmm, I don’t know, probably not. It seems like a waste of time.

     

    -What does he think of the candidates? –He doesn’t like any of them.

     

    W: Really? Why do you think it’s a waste of time?

    M: Have you listen to any of their speeches?

    W: Yes, I have. And I agree that their speeches aren’t very good.

    M: Exactly. I can’t believe anything they say.

    They are just saying what they think we want to hear.

    W: Sure, they want to get elected.

    I have admitted that, the system isn’t perfect but it’s all we have.

    M: Whether I vote or not won’t make a difference. It’s all a show.

     

    -What do they think of the candidates’ speeches? –They are not very good.

     

    W: Well, I think you should vote. Do a little research about the candidates.

    M: Have you?

    W: Yes, I have. I’ve looked into their backgrounds and education.

    M: How can that help?

    W: For example, if they know something about science,

    it could help the government make better decisions about issues such as climate change.

    M: Yes, that’s a good point. We need well-educated people making decisions.

    W: And I looked to see what kind of people are supporting them.

     

    -How has she researched the candidates? –She’s looked into their backgrounds and education.

    -She wants to elect people who are… -smart and well-educated.

     

    M: What issues do you think are most important?

    Lesson 1 Honey Bee Pollination

    Honeybees play an interesting and important role in nature.

    In addition to making honey, honey bees help many plants reproduce.

    They do this by pollenating the plant, which means to transfer pollen.

    Pollination occurs when pollen is moved within a plant’s flower or carried to another flower.

    This is how the plants reproduce.

    For reproduction to succeed, the pollen must be transferred from the male part of the flower to the female part.

     

    -Pollination is how some plants… -reproduce.

     

    Many plants depend on pollination for reproduction.

    These include many fruits and vegetables.

    Besides honeybees, there are many other pollinators, including birds, insects, and other kinds of bees.

    Without enough pollinators, many of our favorite fruits and vegetables would become more expensive and hard to find.

    These include almonds and cherries.

     

    -Besides honeybees, what are some other pollinators? –birds and insects.

     

    Honeybees are important pollinators and play an important role in agriculture.

    Beekeepers are people who keep honeybees.

    In addition to connecting honey, some beekeepers provide pollination services to farmers.

    They do this by raising and managing colonies of bees.

    Farmers need the colonies to pollinate their crops.

    Beekeepers can provide and manager bee colonies for farmers.

     

    -How do beekeepers provide pollination services? –They raise and manage colonies of bees.

     

    Lesson 2 Colony Collapse

    Honey bees are social insects that live in colonies.

    A bee colony consists of a queen bee, male drones, and thousands of female worker bees.

    Each colony also contains eggs and immature bees in various stages of development.

    The number of bees within a colony depends on seasonal changes.

    A colony’s population increases during the warmer seasons, and decreases during colder seasons.

     

    -What does the population of a colony depend on? –seasonal changes.

     

    In recent years many bee colonies have collapsed or disappeared.

    A bee colony collapse occurs when a majority of bees in the colony disappear and leave behind the queen.

    Some beekeepers have reported of losing 30 to 90% of their colonies.

    This loss of bee colonies can cause significant problems for farmers who depend on them to pollinate their crops.

    In some parts of the world, a shortage of bees has increased the cost of renting bees, by up to 20%.

     

    -A bee colony collapse occurs when… -a majority of the bees in a colony disappear.

    -What has increased the cost of renting bees in some parts of the world? –a shortage of bees.

     

    There are several possible causes for bee colonies collapse.

    One possible cause is the use of new pesticides.

    Other possible causes include infections from viruses, genetic factors and malnutrition.

    Changing weather patterns may also play a role as summers get hotter and winters get colder.

    These changes in weather may weaken the bees, making it more difficult for them to fight infections.

     

    -What may make it more difficult for bees to fight infections? –Changing weather conditions.

     

    Whatever the cause of colonies collapse, it’s important to understand that many parts of our world are inter-dependent.

    Changes that affect one species may have serious effects on other species.

    A change to our environment can start a chain of events that is difficult to predict.

    In any complex system, such as the earth’s environment, small changes can have an unforeseen consequences.

    The danger of unforeseen consequences is something we all need to understand better.

     

    -The Earth’s environment is … -a complex system.

    -The main idea here is: -The Earth’s environment is a complex system.

    Vocabulary

    Lesson 4 Business and Economics

    Goods and services supply what people need or want.

    Goods are things such as foods and clothing.

    Services include things such as health care and police protection.

    A country needs natural and human resources.

    Natural resources include fresh water supplies, farmland and energy sources, such as oil and wind.

    Human resources include a skilled workforce that can produce goods and services.

    Once we have a supply of goods or services, they need to be distributed throughout a country.

    Highways and railways are both ways to transport things from one part of a country to another.

    Electricity is distributed through a system of transmission lines.

    We live an age of advertising.

    Advertising lets people know about goods and services.

    It educates people about the product being advertised.

    Trade allows for the exchange of goods and services between different countries.

    Exports are goods and services that are sold to another country.

    Imports are goods and services that are bought from another country.

    For example, many countries import oil from country such as Saudi Arabia.

     

    An advertiser’s goal is to convince people to buy something even if they don’t really need it.

    Without a system of distribution, goods and services cannot be supplied throughout a country.

    Advertisers try to increase the demand for a product or service.

     Lesson 5 Career Building

    Employees are the people who work for a company.

    Some employees do basic work, such as operating a machine, or driving a drunk.

    The people who hire and direct the work of other employees are managers.

    Interviews are one way to find out about a person who applies for a job.

    In an interview, a job applicant can ask questions about the company, and a company can find out about the person’s skills and experience.

    An entrepreneur is someone who starts a new company.

    Entrepreneur often have new ideas and ways of doing things that can give their company an advantage.

    Salary and benefits are used to attract new employees into a company.

    If the salary and benefits are good enough, employees may take the job and stay with the company.

    Benefits include vocation time, health insurance and bonus for employees who do a good job.

    When applying for a job, it’s important to have the skills and experience needed for the job.

    Developing and increasing skills and experience is good way to prepare for a good job. Each job a person has is an opportunity to learn new things and develop new skills.

    Lesson 5 Landlord Trouble

    M: You don’t look good. Is something bothering you?

    W: Yes, it’s my landlord.

    M: Oh, is there something wrong with your flat?

    W: No, there’s nothing wrong with the flat. But I’m going to have to move out.

     

    -What’s wrong with her flat? –Nothing.

    -She doesn’t look good because… -she has to move out of her flat.

     

    M: Why do you have to move out?

    W: For the last two months a friend has been staying with me.

    She is staying until she can find a job.

    M: That’s nice of you.

    W: Yes, but I’m not supposed to have anyone staying there.

    M: Was that in the rental agreement?

    W: Yes, it was. It’s ok if a friend stays for a few days, but not for more than that.

     

    -Her friend was going to stay… -until she could find a job.

     

    M: So you broke the agreement, even though it was for a good reason.

    W: Anyway, one of my neighbors told the landlord about my friend.

    So now I’m in trouble. The landlord is angry and says she can’t trust me.

    M: That’s ridiculous.

    W: I told her about my friend and how I’m trying to help her, but she doesn’t care.

     

    -Who told the landlord about her friend? –a neighbor.

     

    M: Wow, she doesn’t sound very nice.

    W: That’s right, she isn’t nice. She’s just interested in money.

    In fact, she’s going to keep my security deposit.

    M: How can she do that? Nothing is damaged, right?

    W: Right, everything in the flat is fine.

    She’s keeping the deposit because I broke the rental agreement.

     

    -What is the landlord going to keep? –the security deposit.

     

    M: What about your rent?

    W: Yes, that’s another problem. I’ve already pay 3 months’ rent, so I hope I can get it back.

    M: What can you do if she doesn’t return it?

    W: I don’t know. I’ll talk to my agent. He’s nice and maybe he can help.

    Maybe I should refuse to leave the flat until I get it back.

    M: Be sure to take pictures of the flat.

    W: What for?

    M: Just to show the condition of the flat.

    Then she can’t say your friend damage it in anyway.

    W: Good idea. She’s a small-minded evil woman.

    I should never have rented it from her in the first place.

     

    -How many months’ rent has she paid in advance? –She’s paid 3 months’ rent in advance.

    One of the neighbors told the landlord about her friend.

    She doesn’t look good because she has to move out of her flat.

    There’s nothing wrong with her flat.

    Lesson 1 Dream Jobs

    What kind of careers are the best? And what are the qualifications?

    One of the most popular careers for kids is to become an astronaut.

    Many kids dream of going into space when they grow up.

    They dream of working on the space station or exploring deep space.

    To become an astronaut, it’s important to have the right background.

    Many astronauts have the background in engineering, physics or medicine.

    Sometimes they have military background, such as flying military aircraft.

    As for pay, astronauts can earn a good salary, but not great.

     

    Another popular career is to become musician or actor.

    Many kids dream of become famous singers or movie stars.

    However, most musicians and actors don’t become famous.

    They are usually paid by the hour or by the performance.

    Only a very few earn lots of money.

    So the best advice is not become the musician or actor unless that’s your real passion.

     

    Becoming a professional athlete is another dream job for many.

    It’s nice to image playing a favorite sport and getting paid for it.

    However, becoming a professional athlete takes a lot of work and practice.

    Great athletes practice for hours a day with teammates and coaches.

    They also work regularly with trainers to keep their body strong.

    The level of pay for athlete depends on the success and level of their performance.

    Athletes often have short career because of the physical requirements of their sport.

    When they are no longer able to compete at a higher level, some athletes become coaches.

     

    Firefighters and police officers are important jobs that help and protect people.

    These careers require applicants to complete training programs and pass written and physical tests.

    These jobs can be exciting and dangerous so they require courage and sometimes sacrifice.

     Lesson 2 Jobs and Wages

    When considering salary and benefits, some of the lowest paying jobs are hospitality and beauty industries.

    For example food service workers and hair stylist generally have low salaries.

    These kind of jobs don’t require much education or training.

    But again if you enjoy what you are doing, that may be good enough.

    For example, you may really enjoy talking with your customs.

    Spending your life doing something you dislike can be very unsatisfied, even if the salary is high.

     

    Some of the highest paid professions include doctors, lawyers and scientists.

    However, these professions require high levels of education and training.

    The path to becoming a doctor, for example, is a long one.

    Doctors require a university degree, several years in medical school and several more years of experience.

    Only then they are satisfied as a medical doctor or MD.

    So it doesn’t make sense to consider these professions until they for many years.

    And of course, you should really care about doing the work well.

    Vocabulary

    Lesson 3 Types of Wars

    Civil wars are fought between citizens of the same country and are fought within the country.

    If citizens of a country disagree about a policy or leader, they may fight a civil war.

    A world war is fought when countries form alliances and these alliances fight each other.

    A world war involves many or most of the world’s most powerful countries.

    There were 2 world wars in the 20th century.

    Terrorism involves groups of individuals rather than countries.

    Terrorists may come from different countries, and may share the same believes.

    Terrorists often use car bombings and suicide attacks on innocent people.

    A terrorist attack can happen at any time and any place.

    An invasion occurs when one country attacks another.

    It sends its army into the other country and attempts to take control.

    One of the most famous invasions was when France invaded Russia in 1812.

    A defensive of war occurs when a country is attacked and needs to defend itself.

    Most countries have military so that it can defend itself if it’s attacked.

    When France invaded Russia in 1812, the Russian army fought a defensive war and defeated the France army.

     Lesson 4 Biology Terms

    A cell is the basic unit of life.

    A cell is the smallest structure that can live and reproduce.

    Cells grow and develop, reproduce and interact with the environment.

    Photosynthesis is one of the most important biological processes.

    It allows plants to capture and use light as an energy source.

    Photosynthesis is the process of converting light energy into chemical energy.

    A virus is a small biological structure that attacks and inters cells.

    Once inside a cell a virus reproduces and makes many copies of itself.

    Some diseases such as influence are virus.

    Bacteria are one-celled form of life that all around us.

    Although they have a single cell structure they are very important.

    Many bacteria are inside us and help us digest our food.

    DNA is a complex molecule that stores information and can make copies of itself.

    Nearly every cell in a person’s body has the same DNA.

    The information stored in DNA tells cell what to do and is necessary for reproduction.
