一．名词性从句概况（概念、分类、识别）

1.概念

A组 His job is important.

This is his job.

I don’t like his job.

I don’t know about the man, Mr. White.

B组 What he does is important

This is what he does every day.

I don’t like what he does every day.

I don’t know about the fact that he is a teacher.

结论：在复合句中起名词作用的从句叫名词性从句。

名词从句的功能相当于名词或名词性词组, 它在复合句中能担任主语、宾语、表语、同位语。

2.分类：根据不同的语法功能，名词性从句又可分别称为：主语从句、宾语从句、表语从句和同位语从句。

3.识别:

（1）找出主句的谓语动词

（2）主句谓语动词之前的是主语从句；主句谓语动词（及物动词）、动词短语或介词之后的是宾语从句；表语从句位于系动词之后；同位语从句位于某一名词（news ,fact, idea, desire, suggestion, promise, information, situation）之后，作该名词的同位语。Practise: 判断下列句子属于名词性从句的哪种类型

1. What the baby could speak made his parents very happy. ( )

2. I wonder whether you will go shopping or stay at home. ( )

3. This is why he was often late for school.( )

4. We all know the truth that the earth turns around the sun.( )

二、名词性从句的引导词

引导名词性从句的连接词大致可分为三类：

连接词：that，whether，if（不充当句子的任何成分）

连接代词：what，whatever, who, whoever, whom, whose, which.(充当成分)

连接副词：when, where, why, who.（充当成分）

(一)连接词that，whether，if

A: that

1. 判断下列从句类型

That he is still alive is sheer luck. ( )

John said that he was leaving for London on Wednesday. ( )

The fact is that he has not been seen recently. ( )

The fact that he has not been seen recently disturbs everyone in his office. ( )

总结：以上划线部分的共同点：都是完整的句子，都由that引导，that在其中无意义，也不作成分。that可以引导四类名词性从句。

2. 判断下列句子正误。

He is still alive is sheer luck. ( )

John said he was leaving for London on Wednesday. ( )

The fact is he has not been seen recently. ( )

The fact he has not been seen recently disturbs everyone in his office. ( )

总结：通常情况下，that在宾语从句中可以省略，但在其它三类名词性从句中that 不可省。

3 分析下列句子。

（1）I don’t know exactly where he lives, except that it’s somewhere out i n the wilds.（2）He told me he had to leave and that he would be back soon..

（3）We hope, on the contrary, that he will stay at home with us.

（4）That price will go up I know.

分析：以上句子的共同点是：都是由that引导的宾语从句；that都不可省。

总结：that引导宾语从句时不可省的情况有：

(1)当that从句作介宾时；

(2)动词后跟有多个that引导的宾语从句时，只有第一个that可以省；

(3)宾语从句前有插入语时；

(4)that引导的从句位于句首时。

B：whether /if

1. 判断下列从句的类型

（1）Whether it will do us harm remains to be seen. （）

（2）I don’t know whether/if he’ll arrive in time.（）

（3）The question is whether the film is worth seeing. （）（4）There is some doubt whether he will come. （）

总结：划线部分都是完整的句子，其中whether 或if都有“是否”之意；whether

可以引导四类名词性从句；在宾语从句中，whether可用if代替。

2. 判断句子正误并改正

(1) If we can have clean dringking water lies in what effective measures will be

taken by the government about water pollution.( )

(2) It remains to be seen if/whether this idea can be put into practice. ( )

(3) I don’t know if or not the report is true.( )

(4) I don’t know if the report is true or not. ( )

(5) It depends on whether/if we have enough time.( )

(6)They don’t know if to go there.( )

(7)The doctor really doubts whether my mother will recover from the serio us

disease soon..( )

(8)Never once did I doubt that I would be able to carry out my plan.( )

(9) The question is if the film is worth seeing.( )

(10) Answer my question whether you are coming。（）

总结：名词性从句用whether和if均可引导的情况：(a)宾语从句一般情况；（b）主语从句不在句首时； (c)与or not不直接连用时。

名词性从句中只能用whether引导的情况：（a）主语从句在句首；(b)作介词宾语时；

（c）doubt后的宾语从句为肯定句时（否定句时用that）(d)；与or not直接连用时；

(e)与to do连用时(whether to do)

（二）连接代词who, whoever, what, whatever; which, whichever,

whom, whose

判断从句类型，并指出划线部分在从句中所作的成分。

Do you know who has won Red Alert game?（）（）
