1.Although可做让步+转折，Although+句子放句首相当于though，放句中相当于but；
though只用于让步；but只能用作转折；
2.注意转折平行的引导词, but/although，出现时左右要平行
3.Contract to/ In contract with相当于despite，后面只能接抽象名词,而despite+名词短语
4.With引导让步状语从句没有even though好用
5.Even though/although/while在逻辑上是可以相容的，此时根据其他考点排除选项，例
如简洁有效，重复累赘
6.重复：even though与yet/but不能同时出现
Even though there be 错
7.Even if词典ud to emphasize that something will still be true if another thing
happens She's going to have problems finding a job even if she gets her A levels.
Even though 词典ud to emphasize that something is true although something el has happened or is true .Even though he's 24 now, he's still like a little child.
对比可知，even if所接的东西是虚拟的，假设A发生了，B还是会发生。
Even though，虽然A发生了，强调B仍旧会发生. Even if+句子，不能加名词
8.Despite（介词）+名词短语，强调部分
Despite出现经常使句子成分残缺，或表现不出原句的含义，如因果
Despite+n+that/分词结构,容易造成句子累赘且表意不明，这东西没在划线部分正选中出现过，考过非划线部分要加名词短语
9.as oppod to sth，不能加从句
as oppod to sth
ud to compare two things and show that they are different from each other Students discuss ideas, as oppod to just copying from books.
10.just as=even as在比较的时候是一个错误的用法，但可以用于举例,正如…，代替like。使
用前提，不破坏原文的平行或固定搭配。
similar to+n 无法强调动作的相似性，常用just as/as+ 句子代替
like+n，不能加句子
similar to放句首必错
studin spite of =despite 加短语
正确用法：(Just) as从句，主句(Just) as从句，so 主句
(Just )as从句，so too主句
11.平行，主谓一致，固定搭配，简洁性原则>用词准确性
12.Gmat中while用作ud to emphasize the difference between two situations, activities e
tc为多。
AS和WHILE都加句子表示伴随的时候，区别不是很大，看其他考点排除
higher
13.在对比两物时，while强调两者的相同之处，而whereas强调两者的区别，
either的用法
14.while不能用于举例比较。要用just as 或原文本身平行结构
15.无论文中出现那个表示转折的词语，都是要平行，简洁为先，就算哪个选项转折词用对
了，他不简洁或破坏平行都错
16.as表示while和when，没有while直接
17.必错选项：while being
三大作风
Although there be
Even though there be
As being
Despite+句子（一般出现despite就错了）
18.XDF: although,though, even though优先大于contrary，with 做句首
even though / although > despite, in spite of（石林语法）
把LIKE换成SEEM，AS 换成AS IF一定错。As though = as if （石林）
对有些不可能是转折关系的，必须把BUT 改成AND。（石林）
1.in spite of
2.becau of 都有问题
广州美发店contrary to+抽象名词，修饰整个句子不存在逻辑主语问题。C+人名，错
In contrast with/to+名词，比较对象等。
like a bird
unlike固定搭配：unlike x1，x2 do；
unlike/like+名词，放句首表比较
Despite（介词）+名词短语，强调部分
Although+句子
even though+句子，强调整体
while只有放句首才表示让步，放句中表示两者的比较（while there be 错）
19.与其他用法对比：
Even though和although同时放句首，作用相同，看其他考点排除。而放句中时，表转折，even though容易造成句子破碎
20.while, whereas, or although
/doc/9a992326.html,/GMAT_SC/thread-35969-1-1.html
The u of "while" to show contrast is common and accepted in informal usage. In formal writing, however, "while" should be rerved to show that two or more events occur at the same time. In the following ntence, the two events are occurring simultaneously.
Measurements were taken while the specimen was rotating in the rig. For comparisons and contrasts, "whereas" and "although" should be ud instead of "while."
Positions are logged manually, whereas temperatures and pressures are recorded automatically by the thin-film nsors. The two events happen in different ways. They do not necessarily occur at the
same time.
Although positions are logged manually, temperatures and pressures are recorded automatically by the thin-film nsors. The meaning of this ntence is similar to the previous one, but it places more emphasis on the differences between the two events.
Indiscriminate u of "while" where "whereas" or "although" would be more appropriate can even result in ambiguity and misunderstanding:

While my cat, Princess, eats quickly, she enjoys a leisurely stroll.
Does she do both at the same time? Using "whereas" or "although" in this ntence
would clear up the confusion.
In each ntence, lect the best choice for formal writing:
While /Although the method is efficient for most applications,
it can produce errors when small, irregularly shaped specimens are tested.
没什么大不了的英文Place the sample into the rig while / whereas the power is off.

the Materials Division was to develop the composite material for the blade. (The two
projects are not necessarily happening at the same time.)
