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.

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.

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.
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.

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.
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.

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.

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.
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.

Our planet, the earth, is the third planet from the sun.
It is a beautiful, rotating sphere.
The side facing the sun is in daylight.
The side facing away from the sun is in darkness.
For example, when it’s daytime in the US, it’s nighttime in China.
In fact, there’s a 12-hour time difference between Boston and Shanghai.
When it’s midnight in Shanghai,it’s noon in Boston.
-Which side of the earth is in daylight? –the side facing the sun.
-What is the shape of our planet? –a sphere.
-What time of the day is noon? –It’s 12:00 pm.
-Which side of the earth is in darkness? –the side facing away from the sun.
The earth rotates from west to east.
To know which direction is east or west, watch the sun.
The sun travels through the sky from east to west.
The sun comes up in the east and goes down in the west.
Again, this is because the earth rotates.

Europe and the US are separated by several time zones.
When it’s 5 pm in Paris, it’s 11 am in Boston.
So there is a 6-hour difference between Paris and Boston.

As a result, at the same time, some parts of the country can be dark and other parts can be light.
-Which large country has only one time zone? –China.
-Why is the earth divided into time zones? –It rotates.
As you travel around the earth, the time changes.
The time of day depends on your location on the planet.
When you travel east or west, you may cross several time zones.
For example, if you travel from Beijing to Los Angeles, you cross 8 time zones.
That means, when it’s noon on Sunday in China, it’s 8 pm on Saturday in Los Angeles.
For travelers, this means it can be very difficult to sleep after a long flight.
The clock may say 8 pm, but for your body, it’s noon.
This is called jet lag.
-What causes jet lag? –crossing several time zones.
-What happens if you travel east or west? –You may cross several time zones.
-What changes as you travel around the earth? –the time.

Matter is made of atoms and molecules.
Water, for example, is the H2O molecule.
This means that a molecule of water has 3 atoms.
A water molecule has 2 hydrogen atoms and one oxygen atom.
Substances like sugar have many atoms in their molecules.
A molecule of sugar has many atoms, including carbine, hydrogen and oxygen.
-What is H2O? –The water molecule.
-What is matter made of? –Atoms and molecules.
Matter is made of molecules such as the H2O which is the water molecule.
Matter can be in one of 3 states, solid, liquid or gas.
Water and ice are the same substance, but they are in different states.
These states depend on the temperature of the molecules.
When we heat a substance, the molecules move faster and try to take up more space.
When we cool a substance, the molecules move more slowly.
When we cool a substance to its freezing point, it becomes a solid.
-How many states of matter are there? –Three.
-What happens when we heat a substance? –the molecules move faster and try to take up more space.
-What happens if we cool a liquid to its freezing point? –It becomes a solid.
In a solid, the molecules move very little.
Their positions are almost fixed.
To be fixed means that their positions don’t change.
If we heat the molecules, they move faster and away from each other.
The solid begins to melt, like ice cream on a hot day.
-How can we change a solid into a liquid? –heat it up.
-How can we change a liquid into a solid? –cool it down.
At a certain temperature, a solid begins to change into a liquid.
The temperature at which a solid changes into a liquid depends on the substances.
For water, the solid begins to change into a liquid when its temperature rises to above 100 degrees Celsius.
For some substances, such as steel, the temperature at which it becomes a liquid is much higher.
Steel often melts at around 1370 degrees Celsius.
-At what temperature does ice begin to melt? –Above 0 degree Celsius.
-What does the temperature at which a substance begins to melt depend on? –The substances.
If we continue to heat a liquid, the molecules move even faster.
At a certain temperature, the liquid begins to change into a gas.
For water, the liquid begins to change into a gas at 100 degrees Celsius. This is the boiling point of water.
-What happens if we continue to heat a liquid? –Molecules move even faster.
Inside a star, such as our sun, the temperature is very high.
Everything inside the sun is a gas.
According to scientists, there are over 65 elements inside the sun.
These include oxygen and iron.
Over 90% of the sun is hydrogen gas.
-How many elements are inside the sun? –More than 65.

Last month Paul went on a trip.
He went to Japan and China.
There were a couple of reasons for the trip.
One reason for the trip was for business.
He wanted to start some restaurants in both countries.
The other reason was for pleasure.
Paul enjoys travelling and he wanted to visit some friends.
-What was he thinking about starting in both countries? –some restaurants.
Before leaving on the trip Paul had several problems.
First his passport was going to expire.
As a result he needed to apply for a new passport.
Second he needed to get a visa to enter China.
In order to apply for a visa, he needed his new passport.
He had 6 weeks to get everything done.
-Why did he need a visa? –He needed a visa to enter China.
After applying for a new passport it took 2 weeks to get it.
Once he got the passport he went to the Chinese consulate in Toronto and applied for a visa.
He filled out an application form and stood in a long line.
He was surprised by how many people were applying for visas. It took more than an hour to submit his application.
-How long did it take to submit the application? –It took more than an hour to submit it.
-Why did he go to the Chinese consulate? –To apply for a visa.
He submitted his application for the visa on a Friday.
A week later he went back to the consulate to pick up his visa.
To his surprise, when he got there, the consulate was closed.
The consulate was closed because it was a Chinese holiday.
Paul was angry at himself for not checking the consulate’s website.
On its website the consulate’s schedule was posted.
There was a notice saying that the consulate would be closed that day.
-Why was the consulate closed? –It was a Chinese holiday.
As a result, Paul had to come back the next Monday.
This was because the consulate was closed on weekends.
Finally on Monday, he got the visa and he was ready to go.
-Why did he have to wait until Monday to come back? –The consulate was closed on weekends.
Another problem with the trip was his travel schedule.
He needed to extend his stay in Japan.
One week in Japan wasn’t enough.
3 Japanese restaurant owners wanted to meet with him.
He needed more time for the meetings than a couple of days.
And he didn’t want to miss staying with the good friend of his.
-What did he need to do his schedule? –He needed to extend his stay in Japan.
-What didn’t he want to miss? –Staying with a good friend of his.
His friend lives near Mountain (Mt. for short) Fuji and owns a great restaurant.
This was one thing Paul didn’t want to miss.
As a result he extended his stay in Japan.
Instead of staying for just a week, he decided to stay for 10 days.
-What does his friend own? –He owns a great restaurant.
As a result he had to change the dates for staying in China.
The meetings in China were delayed by 3 days.
Instead of arriving on the 1st of the month, he arrived on the 4th.
Fortunately, there were no problems with his new schedule in China.
-What problems were caused by his new schedule in China? –It didn’t cause any problems.
However there were fewer meetings than he expected.
There wasn’t much interest in opening new Italian restaurants. Still, he had one very good meeting.
He met a young Chinese restaurant owner who was interested.
The young man already has a restaurant, but he wants to improve it.
He and Paul liked each other right away.
They met twice in Beijing and are planning to meet again.
-How much interest was there in opening new Italian restaurants? –not much.
-How many times did Paul meet the young man? –They met twice.
The young Chinese man’s name is G.
He is planning to come to see Paul.

Earth is where we all live.
It is our home in the solar system.
There is no other place for us to live.
Earth isn’t just any planet.
It’s a very special place.
It’s special because we depend on it for many things.
Because of its importance we need to take care of it.
-Why is earth so specially? –We depend on it for many things.
We depend on the earth for its air, its water and many of its nature resources.
Nature resources such as coal and oil give us energy.
Other nature resources we depend on include forests and soil.
Forests provide clean air and wood for building houses.
Soil is needed to grow plants and keep them healthy.
We need to take care of these resources and not to waste them.
-What are examples of nature resources? –Coal and oil.
-What don’t we want to do with nature resources? –We don’t want to waste them.
The earth is a large, rotating sphere, about 4.5 billion years old.
The equator, which divides the earth into two hemispheres, is about 40 thousand kilometers long.
The earth’s diameter is 12756 kilometers.
Its radius is half that, or 6378 kilometers.
The radius is the distance from the earth center to its surface.
Most of the earth’s surface is covered by water.
About 75% of the earth’s surface is covered by water.
The rest of the earth’s surface is land.
-What divides the earth into two hemispheres? –The equator.
-Besides water, what is the rest of the earth’s surface? –The rest of the earth’s surface is land.
Just above the earth’s surface is the atmosphere.
The atmosphere is a layer of gases about 500 kilometers thick.
These gases include oxygen, nitrogen and carbon dioxide.
This mixture of gases is the air that we breathe.
As we move about the earth’s surface, the air gets thinner.
At high altitudes, the air is too thin to breathe.
At the edge of the atmosphere is space.
There is no air at all in space.
-Why can’t we breathe at very high altitudes? –The air is too thin.
-What is at the upper edge of the atmosphere? –Space.
-About how thick is the atmosphere? –It’s about 500 kilometer thick.
Most of the earth’s water is in the oceans.
The two largest oceans are the Pacific and Atlantic Oceans.
Unfortunately, we can’t drink ocean water.
This is because ocean water has too much salt.
Fortunately there is also water in lakes and rivers. These water isn’t salty so we can drink it.
Only about 2% of the world’s water is fresh water.
Without fresh drinking water we can’t live.
A person can’t live for more than a few days without water.
-How is fresh water different from ocean water? –Fresh water isn’t salty.
-Why can’t we drink ocean water? –It has too much salt.
One problem with ocean water is that we cannot drink it.
Rivers are important.
Most rivers begin in mountains and end in the oceans.
The water flows from high ground to low ground.
At first rivers are small and are called creeks or streams.
As water enters from other streams, a river grows.
-Where do most rivers end? –In the oceans.
-In which diction do rivers flow? –It flows from high ground to low ground.
Some rivers become very large and long.
The longest river in the world is the Nile River, in Africa.
It’s almost 6500 kilometers long.
As for water volume, the Amazon is the largest river.
The volume of water flowing through it per second is more than in any other river.
-What is the world’s largest river by volume? –The Amazon, in South America.
Another use of rivers is for energy.
The energy of falling water is used to produce electricity.
This use of water supplies over 20% of the world’s electricity.
Rivers are also important for agriculture.
Without water, farmers cannot grow food.
And of course rivers can be used for transportation.
Riverboats are used to carry things to inland cities or lakes.
-How do farmers depend on rivers? –They are needed to grow food.

There are many forms of life on Earth, including human beings.
Life exists in a variety of conditions.
Some forms of life live in a watery environment, like the oceans.
Other forms of life can be found in very dry areas, like deserts.
However, for any form of life to exist, conditions must be right.
When conditions are not right, that form of life will become extinct.
To become extinct means to die out completely.
-What must be right for life to exist?-Conditions.
-What happens if conditions are not right? –Life cannot exist.
Conditions must be right for life to exist.
Millions of years ago, there were forms of life that no longer exist.
When conditions changed, these forms of life died out.
One extinction event happened about 250 million years ago.
This was the largest extinction event of all time.
Many forms of life became extinct.
96% of all life in the oceans died out.
Most insects also became extinct.
This event happened over a period of several million years.
-What happened about 250 million years ago? –Many forms of life became extinct.
-What happens in an extinction event? –Many forms of life became extinct.
The causes of this extinction event are still unknown.
Possible causes include large volcanic eruptions and global warming.
Some scientists believe that there were several causes.
They believe that a series of events caused the extinctions.
Scientists are working to better understand what really happened.
-What is the one possible cause of this event? –Volcanic eruptions.
In modern times, we humans face changing conditions.
For humans to live, we need clean air and clean water.
Pollution is now a growing problem around the world.
Pollution poisons the air and water that we depend on.
Polluted air makes people sick and afraid to go outside. Polluted water poisons our food supply.
As a result, we never know which foods are safe to eat.
Human beings cannot live in a poisoned environment.
Therefore, pollution is a major threat to our existence.
-What do humans need to live? –Clean air and clean water.
-What poisons the air and water? –Pollution.
Humans need temperatures to be in a comfortable range.
To be in a comfortable range means to be neither too hot nor too cold.
With global warming, global temperatures are rising.
As temperatures rise, the polar icecaps will melt.
As the polar ice caps melt, ocean levels will rise.
Areas of some countries will soon be under water.
People will be forced to relocate from flooded areas.
-As temperatures rise, what will happen to the polar icecaps? –The polar icecaps will melt.
-As the polar icecaps melt, what will happen? –Ocean levels will rise.
In nature, even small changes can sometimes have large effects.
It’s difficult to predict what’s going to happen.
The entire ecosystem that we depend on is changing.
Some of these changes are irreversible.
Irreversible changes cannot be undone.
-What can small changes sometimes cause? –Large effects.
-What is happening to the world’s ecosystem? –Ecosystem is changing.
Let’s hope that humans are smart enough to understand how the world is changing.
With more understanding, we can make better choices about what to do.
We can face the challenges of pollution and global warming.
We need to do this before it’s too late.
This planet Earth is our only home and we need to protect it.
-What challenges do we need to face? –Pollution and global warming. We need to protect the environment that supports us.
Mammals are covered by hair or fur, have a backbone, and are warm blooded.
All female mammals produce milk for their young.
Reptiles are covered by scales, and includes snakes, lizards and turtles.
Reptiles have a backbone and are cold blooded, which means they often relied on the external source of heat.
Birds are covered by feathers and are warm blooded.
Most birds can fly and many types of birds migrate great distances.
Most insects such as ants and bees have a small three part of body with three pairs of legs.
Some insects, like mosquitoes, spread diseases that cause the deaths of many humans.
Unlike animals, plants get the energy that they need from the sun.
Plants convert light energy, along with carbon dioxide and water, into chemical energy.
Insects don’t have a backbone and most are cooled-blooded.
Insects such as ants and bees live in well-organized colonies.
Mosquitoes cause the deaths of more humans than any other animal.
Mammals include some of the most intelligent animals on earth, such as elephants and human beings.
Scales and rulers are used to measure weight and length.
Units of weight include kilograms and pounds, and units of length include centimeters and inches.
These instruments are used to observe very large and very small objects.
Telescopes are used to by astronomers and microscopes are used by biologists and doctors.
These appliances are used in the kitchens of almost every home.
Stoves are used to heat food and refrigerators are used to keep foods cool or cold.
Household tools like these are used to build and repair things.
Hammers are used to pound in nails and screwdrivers are used to turn a scow.
If you need to pound in a nail, use a hammer.

Harry is on a business trip.
Yesterday he was supposed to fly from San Francisco to Shanghai.
However, things didn’t turn out the way they were supposed to.
In fact, nothing went the way it was supposed to.
Everything went wrong and he didn’t get on his flight.
As a result, he is still in San Francisco.
-What was he supposed to do yesterday? –Fly to Shanghai.
-When was Harry supposed to fly to Shanghai? –Yesterday.
The following is the summary of what happened.
Yesterday morning he got up as usual and had breakfast.
Everything seemed to be fine and he was looking forward to the trip.
He was just about to check out of his hotel when he felt a pain.
It was a pain in his lower back.
It was a doll pain at first, not too bad.
So he didn’t worry about it and he checked out of the hotel.
Then he got on a shuttle bus to the airport.
-Where was the pain located? –It was a pain in his lower back.
-Why didn’t he worry about the pain? –It wasn’t too bad at first.
About half way to the airport, the pain in his back started to get worse.
It was a growing pain, and he was beginning to worry.
Soon it was difficult for him to sit in the seat.
The pain was getting worse.
He wanted to lie down.
He started to sweat and breathe quickly.
He was in real pain then.
On a scale of 1 to 10, the pain was an 8.
-How was the pain changing? –It was getting worse.
-Why did he want to lie down? –It was difficult for him to sit in the seat.
When the bus got to the airport the bus driver helped him get off.
It was difficult for him to walk but he finally made it to the terminal.
Inside the terminal he went to the man’s bath room. He went to the toilet but that didn’t help.
Instead of improving he felt dizzy and he threw up.
By now he was wet for all the sweating.
He knew he couldn’t get on his flight.
-How did he feel after he went to the toilet? –He felt dizzy and sick.
-Where did he go once he got inside the terminal? –He went to the men’s bathroom.
He used his phone to call the airline.
He explained the situation and cancelled his reservation.
Then he called 911 for emergency help.
911 is the emergency number to call for help in the United State.
-What did he do to his reservation? –He cancelled it.
-Why did he call 911? –He called 911 for emergency help.
An ambulance arrived about 10 minutes after he called.
By then he was in so much pain that he could barely walk.
Once inside the ambulance they gave him oxygen to help him breathe.
But the pain was still terrible.
Then they drove him into a hospital near the airport.
Luckily the hospital was on his health plan.
That means his health insurance is supposed to pay for everything.
Medical costs in the United States are very high.
-Who was supposed to pay for his medicine care? –His health insurance company.
-What did they give him inside the ambulance? –They gave him oxygen to help him breathe.
When he arrived at the hospital he was taken into the emergency room.
After some test a doctor told him he had a kidney stone.
It was a very small stone but it caused a lot of pain.
It was passing through a small turbine his body from his kidney to his bladder.
The pain would go away once it got to his bladder.
Until then he had to get pain medicine to reduce the pain.
-Where was he taken when he got to the hospital? –He was taken to the emergency room.
-What did he take to control his pain? –Some pain medicine.
Harry didn’t have to stay at the hospital for very long.
With the pain medicine the pain went away very quickly.
He took a taxi back to his hotel and checked in for another night.
Then he called the airline and made reservation for another flight.
The flight will leave tomorrow.
Until then he’ll just rest in his hotel.
There may even be a good movie to watch.
-Where will he be until his next flight? –He’ll stay in his hotel.
-What is he going to do until his next flight? –He is going to have some rest.
So when you are travelling, please be prepared for emergencies.
Make sure you have medicine insurance.
You never know when something like this can happen to you.
So be prepared.
-What should you have before travelling? –Medicine insurance. It’s a good idea to have medicine insurance before travelling.
Solar energy is one of the cleanest and most plentiful sources of energy.
Solar power depends on sunlight, so in cloudy weather and at night, no power is generated.
Wind energy is nonpolluting but is only useful in place where there is a lot of wind.
Wind turbines convert the kinetic energy of the wind into mechanical power.
Nuclear energy is efficient and doesn’t produce carbon gases as a waste product.
The dangers of nuclear power include deadly radioactive waste products.
A major source of energy comes from the burning of fossil fuels, such as coal and oil.
When we burn fossil fuels, waste gases such as CO2 are produced.
Fossil fuels remain the largest source of energy for most countries.
Hydropower comes from the kinetic energy of falling water.
Output is reliable and can be regulated to meet the demand, except during the periods of drought.
One of the main problems we face is how to reduce the use of the fossil fuels to produce energy.
We need to reduce the use of the fossil fuels to produce energy. Dams are expensive to build and affect wildlife such as fish.
Here are some different types of words in English.
Words that are nouns or pronouns are used to represent objects.
A noun or a pronoun can be a person, an animal or a thing, including an idea.
Verbs are used to express actions, such as to sit down, or stand up.
We also use verbs to express relationships, such as to love someone or to own something.
We used adjectives to describe objects, such as a tall building.
Adjectives are used with nouns and pronouns, but not with verbs.
We use adverbs to describe actions, such as to run fast or walk slowly.
Adverbs express the quality of an action, such as how well or poorly something is done.
We use conjunctions to connect things or actions, such as to read and write.
Conjunctions include words such as and, or, because, but, and yet.
Nouns and pronouns can be used to represent any object.
W: Hey, I’ve got some news, some good news and some bad news.
M: OK, give me the bad news first.
W: We are moving to a new office.
M: When is this going to happen?
W: We are supposed to move at the end of next month.
M: How far away is the new office?
W: We are not sure yet. But it will mean a longer commute for most of us.
The new office will probably be on the other side of the city.
M: The commute is already too long for me and I’m not going to change flats. We just bought one.
-What did he just but? –He just bought a new flat.
-How is the move going to affect the commute? –It’ll make the commute longer for most of the employees.
M: Anyway, what’s the good news?
W: The good news is that we are going to expand.
The company is growing so we are going to hire more people.
M: Well, I’ve got some news for you too.
W: I hope it’s a good news.
M: Well, that depends on your point of view. I’m planning to start my own business.
W: Why? I thought you were happy working here.
M: I like the work, but I’m not learning anything new. I think I can do better on my own.
-Why is the company going to hire more people? –The company is growing.
M: I was planning to wait a few months. But now that the office is moving, I’m ready to make the change.
W: What is your wife think?
M: She’s in fever of it and she will help me. She’s already designing a website.
We’ll work from home at first.
W: So you really are serious about this? You’re taking a big risk. Most new businesses fail.
M: Yes, I know, but if I don’t do it now, I never will. I’m tired of working for others.
W: I know what you mean.
-What does his wife think his decision? –She’s in favor of it.
-What is he serious about? –He is serious about starting his own business.
M: Don’t tell anyone about this, OK? It’s still a secret.
W: Sure, I won’t say anything to anybody. I’m sure this will come as a surprise to everyone.
M: I’m sure changing offices will also come as a surprise to people.
This is exactly why I want to work on my own. I don’t like these kinds of surprises.
W: You are right about that. When are you going to let people know?
M: I’ll make the announcement at the beginning of next month.
-What is a secret? –His decision to leave the company.
-When is he going to let people know about his decision to leave? –He’ll announce his decision at the beginning of next month.
Leonardo Da Vinci is one of the greatest geniuses of all time.
He was a painter, an architect, an engineer and a scientist.
He was born in Vinci, Italy in 1452.
Vinci is a town just outside the great Italian city, Florence.
His name Da Vinci means of Vinci.
Leonardo’s father was a lawyer and a landowner and his mother was a present.
Leonardo’s parents were never married to each other.
-How long were his parents married? –They were never married.
-Where was he born? –In Vinci, Italy.
Leonardo lived with his mother until he was around 5 years old.
When he was 5, he moved into the home of his father.
By then, his father had married a 16-year-old girl.
Leonardo’s mother married another man and moved to another town.
She had many more children after that, with several different men.
In the end, Leonardo had more than 15 half-sisters and brothers.
-With whom did he live when he was 5? –His mother.
As a young man, Da Vinci didn’t go to school.
He was educated at home in reading, writing and mathematics.
In other subjects, he was mostly self-educated.
He had access to books at his father’s home.
Leonardo spent a lot of time outdoors and developed a strong interest in nature.
He loved to observe things, especially birds.
He was also interested in the properties of water.
-What did he have access to at home? –Books at his father’s home.
-In what did he develop a strong interest? –He developed a strong interest in nature.
Leonardo’s early drawings and paintings demonstrated a rare talent.
His father and his father’s friend recognized his talent and encouraged him.
When he was 15, he was sent to Florence.
In Florence, he became an apprentice to a famous master painter.
For the next few years Leonardo worked at his master’s workshop.
It wasn’t long before his ability surpassed that of his master.
Some people say that his master became jealous about Leonardo’s greatest talent.
They say that the master vowed to never paint again.
In 1478, with his father’s help, Leonardo set up his own workshop.
-Who became jealous with Leonardo’s talent? –His master in Florence.
In 1482, he entered the service of a powerful man in the city of Milan.
This man was the duke of Milan.
For the next few years, Leonardo designed buildings, machinery and weapons of war.
Weapons were important because Italy was constantly at war during this period.
From 1485 to 1490, Leonardo produced designs for a variety of weapons.
In his notes, he predicted the development of advanced weapons such as submarines and flying machines. In 1499, the French invaded Italy, and Leonardo left Milan.
-Why did Leonardo live Milan? –The French invaded Italy.
-Who did Leonardo work for in Milan? –He worked for the duke of Milan.
All together Leonardo spent 17 years in Milan.
During this period he spent much of his time studying in nature.
He dissected bodies, both human and animal, to study an illustrate anatomy.
His detailed illustrations are masterpieces.
Leonardo filled many notebooks with drawings and ideas.
He wrote backwards so you need a mirror to read them.
-Why do you need a mirror to read his notebooks? –He wrote backwards. He left Milan because the French invaded Italy.
After 1500, Leonardo spent time in a number of Italian cities.
He worked very slowly and the range of his interests was very wide.
As a result Leonardo left many paintings and projects unfinished.
One painting that he did finish was the Mona Lisa, one of the world’s most famous paintings.
People are still interested in this painting, 500 years after he painted it.
Though there are many theories nobody knows who the woman in the painting really was.
-Why did Leonardo leave so many projects unfinished? –He worked slowly and had a wide range of interests.
-Who was the woman in the painting? –Nobody knows for sure.
In 1516, Leonardo left Italy for good when the French King, Francis I (the first), offered him a position.
There he had a freedom to paint and draw whatever he wanted.
Leonardo died in 1519 at the age of 67.
Some said that the French king who had become a close friend was with him when he died.
He was buried in the church which was destroyed during the French revolution.
The exact location of his remains is unknown.
-How old was he when he died? –He died at the age of 67.
-Who offered Leonardo a position in 1516? –The king of France.
Waste water and carbon gases from farm animals are bad for the environment.
Animals waste and other chemicals flow into the ground and pollute water supplies.
Exhaust gases from automobiles are a major cause of air pollution and global warming.
As a result many companies are trying to produce more efficient and cleaner cars.
Pesticides and fertilizers are used by farmers to grow crops such as fruits and vegetables.
These chemicals pollute water supplies when they flow into the ground or rivers.
Factories like this one allow harmful chemicals to get into the air or water.
Companies need to try harder to protect the environment and our health.
Nuclear waste products are radioactive and can pollute the environment for thousands of years. They need to be safely transported and stored in a safe place.
Nuclear waste products need to be stored in a safe place.
The British writer, Jane Austin, was born in England in 1775, one of seven children.
She wrote some of the most popular love stories of all time.
One of the most famous female rulers in history, Cleopatra had affairs with Julius Caesar and later with Mark Antony.
She was known for her great beauty and charming voice.
Born in 1756, Mozart composed and performed some of the world’s greatest classical music.
He was the youngest of 7 children and by the age of 5, he was already composing music.
The sun of the king, Alexander the great, was the military leader who created one of the largest empires in the ancient world.
As a youth, Alexander was taught by the Greek philosopher Aristotle.
Mohandas Gandy was a 20th century leader who used non-violent resistance to lead India to independence. Gandy dedicated his life to the pursuit of truth.
Mozart started writing music as a young child.
M: I’d like to speak with Mr. Bennett, please.
W: I’m sorry, but he’s not here right now. Would you like to leave a voice message?
M: It’s urgent that I speak with him. It’s an emergency.
W: Oh, I see. What kind of emergency?
M: It’s very personal so I can’t give you any details.
-What does the word urgent mean? –Need quick attention.
-Why doesn’t he want to leave a voice message? –It’s an urgent matter.

M2: Thanks for the offer, but I can handle it.
-Why does he want to pay? –It’s his turn to pay.
M1: Wait, let’s flip for it.
M2: Flip for it? What does that mean?
M1: Do you see this corn? This side is heads and the opposite is tails. I’ll flip up in the air.
If it comes down with heads facing up, I’ll pay. If tails are the up, you can pay.
M2: OK, that’s fine with me.
-How are they going to decide who is going to pay? –They are going to flip a corn.
M1: Look, it’s heads up, so I’ll pay.
M2: Thanks, it’s very nice of you.
M1: It’s my pleasure.

M: No, thanks, I’m ready for the check. Here is my credit card.
W: I’m sorry, Sir, but we don’t take credit cards.
M: You’re joking, right?
W: No, sir. I’m not joking. Do you see that sign? It says cash only.
M: I didn’t see it when I came in. I don’t have enough cash to pay the bill.
-How did he plan to pay? –He planned to pay by credit card.
-Why can’t he pay? –He doesn’t have enough cash.
W: There is a bank down the street.
If you let me hold your driver’s license, you can go and get the cash.
M: OK, I hope the bank is open.
W: The bank is closed, but you can use the ATM to get your cash.
-Where can he get the cash? –He can get the cash at an ATM down the street. He has to leave his driver’s license with the waiter.

- What is in-place operation?
- Encounter the RuntimeError: one of the variables needed for gradient computation has been modified by an inplace operation。
inplace operation就是直接对tensor的内容进行修改，而没有使用复制的副本 （An in-place operation is an operation that changes directly the content of a given Tensor without making a copy）。
.scatter_()导致的。对于.add_()方法，是直接在tensor上进行修改的，可以把x.add_(y)改成x = x + y。如果需要复制一个副本话，参照第二个帖子的方法，可以使用.clone()方法。
*=导致的。比如 x += y，需要改成 x = x +y
