高考英语语法知识点总结
主语从句
主语从句是在复合句中充当主语的从句，通常放在主句谓语动词之前或由形式主语it代替，而本身放在句子末尾。
1. It 作形式主语和it引导强调句的比较。
It 作形式主语代替主语从句，主要是为了平衡句子结构，主语从句的连接词没有变化。而it引导的强调句则是对句子某一部分进行强调，无论强调的是什么成分，都可用连词that。被强调部分指人是也可用who/whom。
例如：
It is a pity that you didn’t go to see the film.
It doesn’t interest me whether you succeed or not.
It is in the morning that the murder took place.
It is John that broke the window.
2. 用it 作形式主语的结构。
(1) It is +名词+从句
It is a fact that … 事实是…
It is an honor that …非常荣幸
It is common knowledge that …是常识
(2) it is +形容词+从句
It is natural that… 很自然…
It is strange that… 奇怪的是…
(3) it is +不及物动词+从句
It seems that… 似乎…
It happened that… 碰巧…
(4) it +过去分词+从句
It is reported that… 据报道…
It has been proved that… 已证实…
3. 主语从句不可位于句首的五种情况。
(1) if 引导的主语从句不可居于复合句句首。
(2) It is said ， (reported) …结构中的主语从句不可提前。
例如：
It is said that President Jingo will visit our school next week. (right)
That President Jiang will visit our school next week is said. (wrong)
(3) It happens…， It occurs… 结构中的主语从句不可提前。
例如：
It occurred to him that he failed in the examination. (right)
That he failed in the examination occurred to him. (wrong)
(4) It doesn’t matter how/whether …结构中的主语从句不可提前。
例如：
It doesn’t matter whether he is wrong or not. (right)
Whether he is wrong or not doesn’t matter. (wrong)
(5) 含主语从句的复合句是疑问句时，主语从句不可提前。
例如：
Is it likely that it will rain in the evening? (right)
Is that will rain in the evening likely? (wrong)
4. What 与that 在引导主语从句时的区别。
What 引导主语从句时在句时在从句中充当句子成分，如主语.宾语.表语，而that 则不然。
例如：
1) What you said yesterday is right.
2) That she is still alive is a consolation.

倒装结构
学生容易混淆的是全部倒装与部分倒装.如何区分之,编个顺口溜：副(adv.)介(prep.)提前全倒装,其它句式部分倒;否定提前倒助动,让步状语倒表语;复合句式倒主句,不
倒装的属特殊.下面举例说明：
A、Here comes the bus.(副词提前,全倒装)
B、Here he comes.(代词作主语,不倒装)
C、In front of the house lies a garden.(介词短语提前,全倒装)
D、Never shall I do this again.(否定词提前,部分倒装)
E、Young as he is ,he knows a lot.(让步状语从句,表语倒装)
F、Only when he told me did I realize what trouble he was in.(only 修饰状语,主句倒装)
G、Only he can save the patient.(only修饰主语.不倒装)
H、Not only will help be given to people,but also medical treatment will be provided.(否定词提前,部分倒装)
I、Not only he but also we like sports.(连接两个主语,不倒装)
虚拟语气
虚拟语气也是一个难点.所谓虚拟语气是表示说话人的愿望、假设、猜测或建议,而不表示客观存在的事实.它通过句子的谓语动词的特殊形式来表示.现归纳如下：纯假设,用虚拟,动词时态退一级：条件句,分主从,主句谓语前加would (should,could,might);表愿望,用虚拟,wish后面接宾语(从句)：现在过去与将来,动词时态退一级：提建议,用虚拟,宾语(从句)动词用(should)do：俩建议,三要求,再加坚持与命令(suggest,advise,demand,require,request,insist,order)：It is time和eoukd rather,后接丛句用虚拟：部分主语从句中, 谓语用虚拟结构 (It is necessry /important/natural/natural/strange/strange that……should do). 下面举例说明：
A、If you came tomorrow,we would have the metting. (条件句虚拟)
B、Without air,there would be no living things.(同上)
C、We wish we had arrived there two hours earlier.(表示愿望虚拟)
D、He demanded that we (should)start right away.(表示建议虚拟)
E、It is(high)time that we left (should leave)now.(特殊从句虚拟)
F、I would rather you gave me the book.(同上)
G、It is necessary that we should clean the room everyday,(主语从句虚拟)
H、He speaks English so fluently as if he were English. (特殊从句虚拟)
