第六课  英语的特殊结构

1、强调句型

It is...that / who / which(少见)...

* 强调句型可以强调句子中所有成分(唯一不能强调谓语)*

 It is obviously that I love you.  (强调句型)

 It is obvious that I love you.

2、倒装

 1)什么是倒装

倒装就是把一句话写成一般疑问句形式,也就是给一句话加助动词或把be动词放在句首

 2)倒装的具体用法

·  否定词放在句首用倒装

I can hardly speak Japanese.

Hardly can I speak Japanese.

I by no means love you.

By no means do I love you.

·  so,nor / neither 位于句首,表示承前句子的肯定或否定表示倒装

·  含有 so...that...结构的句子将 so 引导的部分置于句首时用倒装

·  only 引出的状语从句放句首时用倒装

·  as 引导让步状语从句,从句表语可以放在句首构成部分倒装

·  省略 if 的虚拟语气用倒装

 2)倒装的具体用法

- 写作

·  文化交流不但能促进我们国家经济发展,而且还能开阔个人视野

·  Not only can cultural exchange promote economic advance but also make our eyesight broad.

·  我累得浑身都没劲了

·  So exhausted am I that I have no energy throughout.

- 长难句分析

还原倒装部分后再作翻译

3、虚拟语气

虚拟语气表示与事实相反或语气委婉

一般用法:

If 引导的条件状语从句

· If you are were a tear in my eyes,I will would never shed it.  (虚拟语气)

· If I was had been a dog last night,I could sleep have slept with you in bed.

如何把正常条件状语从句变成虚拟语气:

只需要把已写好句子的时态变为过去式,并且在虚拟语气中(be 动词的过去式为 were,could = would = might)

If I remembered you in my next life,we would never seperate with each other.

特殊用法:

1)以下情况从句用 " should + v." 表示虚拟,并且should可以省略。

以防:incase,lest,for fear that

命令:order,direct,command

建议:advise,suggest,propose

要求:ask,request,demand,require  用虚拟

是必要的:It is necessary / important that...

例:In case that you should develop fatal infections,you had stay at home.

  It seems crucial that more activities should(可省略) be attended to show myself.

2)以下情况从句用过去式时表示虚拟

用一般过去式时表示虚拟:常见 would rather 与 It is high time that...

  It is high time that the independance of kids were cultivated by senior citizens.

3)以下情况区别对待

把本来时态写成过去式:

· 常见词 wish,if only,but for,or/otherwise,as though/as if(好像,似乎)

 If only I were your child.

 If only I had been your child.

4、情态动词

1. 情态动词 + 动词原形(表示对现在和将来的推测)

I must be wealthy in the future

It can be a boy

2. (表示对过去的推测)

He must have been self-abased in his University.

注:must have done(一定做过某事)  否定:can not  禁止:must not

You need not have shown your love in this way.

注:need not have done(本没必要做某事,但做了)

I could have become a prominent poet.

注:could have done(本能够做某事却没有做,表示遗憾)

We should have got married if there exists a chance.

注:should have done(本应该做某事,却没有做)
