高三英语语法知识点1
强调句句型
1. 陈述句的强调句型:It is/ was + 被强调部分(通常是主语、宾语或状语)+ that/ who(当强调主语且主语指人)+ 其他部分 。
e.g. It was yesterday that he met Li Ping.

e.g. Was it yesterday that he met Li Ping?
3. 特殊疑问句的强调句型:被强调部分(通常是疑问代词或疑问副词)+ is/ was + it + that/ who + 其他部分?
e.g. When and where was it that you were born?
4. 强调句例句:针对I met Li Ming at the railway station yesterday.句子进行强调 。
强调主语:It was I that (who) met Li Ming at the railway station yesterday.
强调宾语:It was Li Ming that I met at the railway station yesterday.
强调地点状语:It was at the railway station that I met Li Ming yesterday.
强调时间状语:It was yesterday that I met Li Ming at the railway station.
5. 注意:构成强调句的it本身没有词义;强调句中的连接词一般只用that,who,即使在强调时间状语和地点状语时也如此,that,who不可省略;强调句中的时态只用两种,一般现在时和一般过去时 。原句谓语动词是一般过去时、过去完成时和过去进行时,用It was ……,其余的时态用It is …… .
二、not … until … 句型的强调句
1. 句型为:It is/ was not until + 被强调部分 + that + 其他部分
e.g. 普通句:He didn't go to bed until/ till his wife came back.
强调句:It was not until his wife came back that he went to bed.
2. 注意:此句型只用until,不用till.但如果不是强调句型,till,until可通用;因为句型中It is/ was not …… 已经是否定句了,that后面的从句要用肯定句,切勿再用否定句了 。
三、谓语动词的强调
1. It is/ was …… that …… 结构不能强调谓语,如果需要强调谓语时,用助动词do/ does或did.
e.g. Do sit down. 务必请坐 。
He did write to you last week. 上周他确实给你写了信 。
Do be careful when you cross the street. 过马路时,务必(千万)要小心啊!
2. 注意:此种强调只用do/ does和did,没有别的形式;过去时用did,后面的谓语动词用原形 。

as, though, although引导的让步状语从句 。
[注意]although位于句首;though位于句首或句中;as位于句中=though 。它的词序是把句中强调的形容词、副词、动词或名词放在连词前 。[参考倒装结构] 请注意下列句式的变化:
[例句]
1. Although/Though I'm young, I already know what career I want to follow.
→Young as/though I am, I already know what career I want to follow.
我虽然年轻,但我已经明白我应该追随什么样的事业 。
2. Although/Though I respect him very much, I cannot agree with his idea.
→Much as/though I respect him, I cannot agree with his idea. 虽然我很尊重他,但是我不同意他的观点 。
3. Although/Though he is a child, he knows a lot of Chinese characters.
→Child(省略冠词)as/though he is, he knows a lot of Chinese characters. 他虽然还是个孩子,却认识了许多汉字 。
4. Although he tried, he couldn't solve the problem.
→Try as he might, he couldn't solve the problem. 尽管他努力了,但是他没有解决问题 。
5. Although it is raining, I'm going out for a walk.
→Raining as it is, I'm going out for a walk. 天虽然在下雨,我还是要出去散步 。
6. Strange as it may seem, nobody was injured in the accident. 这次意外虽然显得不可思议,却没有人受伤 。

名词性从句的几个难点
(一)that不可省略的情况
1、主语从句,that从句置于句首时;
2、当一个句子有两个或多个并列的宾语从句时,引导第二和以后几个从句的that不可省略;
3、由it作形式宾语时,that引导的宾语从句中,that不可以省略 。
(二)wh-ever与no matter wh-的用法区别
Wh-ever既可引导名词性从句,又可引导让步状语从句;而no matter wh-只能引导让步状语从句 。
(三)as if/though, because, why可以引导表语从句
注意:because引导的表语从句,主语不能是reason或cause,而且since,as不能引导表语从句 。
