摘要：语法的重要性帮帮已经说过很多次了，没有语法基础光靠背单词是不可能读懂长难句，也无法在阅读上取得高分的。为了方便大家记忆，帮帮整理了考研英语语法精炼，希望可以帮助大家更方便的学习英语~

此外，表语从句还可由as if (好像)引导。如：

形容词后的that 从句
that 引导的名词性从句还可以用在一些形容词后面。这种句型一般都用人作主语，所用的形容词都是表示思想状况或感情色彩的形容词，如certain, sure, positive, afraid, convinced, anxious, disappointed, worried, glad, happy, sorry, amazed, surprised, aware, doubtful, confident等等。如：
I am sure/certain that he’s at home now. 我肯定他现在在家。

He remains confident that he will win. 他仍然自信他会赢

what 从句的小结
1.意思是“所….的事/物”, 相当于the thing(s) that…, that which…, 或those which… 可以用于以下情况：
(1) 引导主语从句。如：

But what hurt our feelings most was the personal comment of the judge. 最伤我们感情的是法官的私下评论。
What will be, will be. 要发生的事总是要发生的。(谚语)
What is gone is gone. 过去的事就过去了。
(2) 引导表语从句。如：
That’s what I hope. 那就是我希望的。
I should like to be a teacher. That’s what I want to be. 我想当老师，那是我想干的事。
Times are not what they used to be. 时代不同了。
He’s not what he was a few years ago. 他不是几年前的他了。
Your health is not what it ought to be. 你的身体应该更好。
(3) 引导宾语从句，包括介词宾语。如：
He could not express what he felt. 他不能表达他的感受。
Well, I’ll do what I can. 好吧，我尽力。
I can’t do what you’ve just asked of me. 我不能做你刚才要求我的事。

2.用作插入语，指代后面的成分。这和非限定性定语从句正好相反，非限定性定语从句指代的是前面的成分。如：
Then I discovered, what was news to me, that his wife was Mary’s niece. 后来我发现，他妻子原来是Mary的侄女，这对我是个新闻。
He never joined in the usual sports of the boys, and, what is remarkable, never went out in a boat on the river. 他从来不参加男孩子通常做的体育活动，更奇怪的是，他从来不坐船出去到河上面去。

We invited a new speaker and, what’s more, he was happy to come. 我们请到了一位新的发言人，而且他很乐意来。
3.引导让步状语从句，等于“不管什么…”。注意状语从句的语序。如：
Do what she would, she could not invent a reason for not going. 不管她会做什么，她都编不出不去的理由。状语从句把实义动词放在句首，句子倒装。=No matter what she would do, …
Come what may, you’ll always keep it secret. 无论怎样，你都要保守秘密。=No matter what may come, ….

Say what he will, in his heart he knows that he is wrong. 不管他怎么说，内心里他知道自己错了。= No matter what he will say.
