                                  强调句

 

教学目标：1. 能判断强调句与主语从句、定语从句、状语从句的区别

          2. 掌握it强调句和“what…be…”强调句及其相互转化

 

考点:  1.it强调句（不强调谓语、定语）

a.       It is/was+被强调部分+that/who…..

b.      It is/was not until+被强调部分+that….

       2.用“what…be…”句型（把被强调的部分后移）

       Eg: Her coming deligheted me

       转化为：What delighted me was her coming.(其实就是what引导的主语从句)

       也可用it强调句：It was her coming that delighted me.

 

需要掌握的知识点：

 

1.    区别强调句、主语从句、定语从句、状语从句

 

Eg:It was obvious that he was very embarrassed.(主语从句，it为先行主语)

   It is a question that needs careful cosideration.(定语从句，it为代词)

   It is Tom that takes care of the flowers every day. (强调句，强调主语，it不是先行主语，也不是代词，而是固定模式：It is/was…that/who…

It is /was….that/since/when/while/before等（与状语从句的区别）

分析：用since的话，it后不用was,因为since一定语“现在”有关

Eg：It is two years since I began to learn English.

如果用when，it is /was 后加的是时间点，而while不可以，因为while后面的从句不可能是瞬间动词，而且，it 后用was, 因为事情发生在过去。

          Eg:Was it at five o’clock____the fire broke out?（有无at答案不一样）

          A when         B that        C which        D in which

          如用while,这种情况比较少见

 Eg: “Was it under the tree _____ you were away talking to a friend？” “Sure. But when I got back there, the bike was gone.

  A. that            B. where      C. which           D. while

做好此题的关键是正确理解上下文的语境。在此句中，it 是代词，指代 the bike，句意为：“当你离开去同朋友谈话的时候，你的自行车是在这树下吗？”“当然，但当我回来时，自行车就不见了。”现在反过来分析一下，假若选A，将此句判为强调句，句子即为 Was it under the tree that you were away talking to a friend？ 若进一步转换为非强调句，句子则为 Under the tree while you were talking to a friend，句意显然很荒唐，这样的话，句子结构也有问题，既不是简单句也不是复合句。

 

如果用before的话，可有这几种形式

It wasn’t long before....不久以后就

It won’t long before…不久就会

It was (not) two years/days…before… 两年/两天后(不到两年/两天)就…

It will (not) two years/days…before… 两年/两天后才会…(用不了两年/两天就会…)

也就是说,如用before的话，前面一定是时间段

Eg：It was two years before he came back from abroad.

It won’t be long before we meet again.

 

总结:不管是主语从句,定语从句还是状语从句都是复合句，而强调句可能是简单句，但也不一定，也就是说，被强调的部分也可能是一个句子

Eg：It was what he meant rather than what he said_____annoyed me.让我生气的不是他说的话，而是他话中的意思。

A which           B as           C what        D that

当被强调的成分中含有定语从句时，整个题干也可能是复合句

Eg: It was the boy____had been in prison____stole the money.

A who;where       B that;how      C who;that     D that;which

 

2.      用“what…be”强调句型的话，要区别what引导的与it做先行主语的不同。我们知道what可引导主语从句，it放在主语从句中可作先行主语，真正主语放在后面。关键在于谓语动词的不同。

Eg:____excited us Chinese greatly that Liu Xiang, a Chinese, won the Olympic champion of the 110-meter hurdle race.

A what            B that          C it           D as

       3. 如果强调句是名词性从句，那么

         结构：特殊疑问词+it is/was….

          Eg:I really don’t know____I had my money stolen.

 A when was it that            B that it was when         

C where it was that           D it was where that

 

改成简单句：Where was it that I had my money stolen?

 

注意:容易做错的两种题型:

1.    前面已讲过，就是it是代词，而不是it is(was)……that(who)结构

2.    强调句的省略:

—Who are making so much noise in the garden？

       —_______ the children.

       A. It is                  B. They are    C. That is              D. There are

   如选B/D是答非所问。后面省略了Who are making so much noise in the garden。完整为：It is the children who are making so much noise in the garden.
