　　which或者that定语从句一定修饰前面的名词吗?
我们就来说一下which或者that定语从句到底修饰谁吧!
hold gmat
正常情况下，我们在前面分析的很多期句子当中，定语从句就是往前修饰名词的。不再多举例了。但是有时见到这样的句子：
One such adaptation is the closer proximity of the terrestrial snake's heart to its head, which helps to ensure circulation to the brain, regardless of the snake's orientation in space.
句意理解：
逗号前：这种适应性的一个表现，就是陆地蛇的心脏距离头很近。
逗号后：能帮助保证头部的循环，不管蛇的空间方位。
注意which从句的前面，其实不止一个名词哦。前面有一些介词短语结构，如of…to…等，它们都在修饰the closer proximity，只不过它们很短，挤在了which从句的前面，而我们不可能把which从句放在of…, to…的前面的。
依葫芦画瓢，我们再来看一个句子吧：
But such an argument only tends to obscure the consciousness of identity, strength, and sense of history that already existed in the African American community.
考虑一下，that从句说的是history, sense, strength, identity, 还是consciousness呢?
很明显，of identity, strength, and sense of history是修饰consciousness的，句意上说已经存在于黑人社会里的应该说的核心词是consciousness。
再来一个：
Furthermore, if wages are not allowed to rise, the value of the country's currency will appreciate, which (from the developed countries' point of view) is the equivalent of increased wages in the developing country.
which从句前面根本没有挨着名词诶。。。那肿么办?
记住一句话：
定语从句，不管是限定非限定，不管是that还是which，都试图去修饰一个名词，这个名词跟它在一起，那最好，不在一起，就找一找，总能找到的。找不到就错了。
这个当然也一样啊，which前面没挨着名词，但总是有名词的对不对?再往前不就找到currency了嘛。

1、报错
You are in 'detached HEAD' state, which means that you're not on any branch
Checkout a branch to make update possible.

2、解决办法
1.创建新的分支：git branch   XXXX
2.切换到你的工作分支：git checkout  XXXX
3.合并代码：git merget    XXXX

我是用第二种解决的，不知道啥时候切错了分支，导致Git出现分支游离。
