高考常考高三英语语法知识点

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.

2. 一般疑问句的强调句型:同上,只是把is/ was提到it前面。

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。

7. Much as I would like to help, I have a lot to do. 虽然我很想帮助你,但是我有很多事要做。

8. Object as you may, I will go. 纵使你反对,我也要去。

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。

(四)that引导的同位语从句与关系代词that引导的定语从句的区别

That引导的同位语从句成分是完整的,that在从句中不担当任何成分;that引导的定语从句成分是残缺的,that在从句中充当主语、宾语或表语。

助动词

1)协助主要动词构成谓语动词的词叫助动词。被协助的动词称作主要动词。助动词自身没有词义,不可单独使用。例如:

He doesn′t like English. 他不喜欢英语。

(doesn′t是助动词,无词义;like是主要动词,有词义)

2) 助动词协助主要动词完成以下功用,可以用来:

a. 表示时态。例如:

He is singing. 他在唱歌。(北京安通学校提供)

He has got married. 他已结婚。

b. 表示语态。例如:

He was sent to England. 他被派往英国。

c. 构成疑问句。例如:

Do you like college life? 你喜欢大学生活吗?

Did you study English before you came here? 你来这儿之前学过英语吗?

d. 与否定副词not合用,构成否定句。例如:

I don′t like him.  我不喜欢他。

e. 加强语气。例如:

Do come to the party tomorrow evening. 明天晚上一定来参加晚会。

He did know that.  他的确知道那件事。

3) 最常用的助动词有:be, have, do, shall, will, should, would等。

3 助动词be的用法

1) be +现在分词,构成进行时态。例如:

They are having a meeting. 他们正在开会。

English is becoming more and more important. 英语现在越来越重要。(北京安通学校提供)

2) be + 过去分词,构成被动语态。例如:

The window was broken by Tom.. 窗户是汤姆打碎的。
