高三英语 总复习 (从句) 集锦

五、名词性从句中虚拟语气的使用情况

1、在表示“命令、建议、坚持、要求”的名词性从句中，要用“should+动词原形”形式，should可以省略。 e.g. I made a suggestion that he (should) go there at once.

I suggested that he (should) go there at once.

The suggestion was that he (should) go there at once.

2、wish引导的宾语从句中要用虚拟语气，分与现在、过去、将来相反三种情况。

e.g. I wish I were ten years younger.

I wish you had posted the letter yesterday.

I wish I would try again.

3、在句型“It + is/was + adj.+主语从句”中，如果形容词是important, strange, natural, necessary等，从句谓语部分要用“should+动词原形”形式，should可以省略。

e.g. It’s strange that he (should) think so.

It is necessary that he (should) go there at once.

六、引导同位语从句与定语从句的that的区别

同位语从句中的连词that只起连接作用，不充当任何句子成分且不能省略，同位语从句一般放在有具体含义的名词后，用以解释名词的含义或内容；而定语从句中的关系代词that在从句中充当主语或宾语，在充当宾语时常可省略，定语从句是对先行词的限定和修饰。

e.g. They expressed the hope that they would come to visit China again.

The hope she expressed is that they would come to visit China again.

七、引导名词性从句的that和what的区别

that 引导名词性从句时，在从句中不充当任何句子成分，也没有任何含义，只起连接作用, 且在宾语从句中有时可省略；而what引导名词性从句时，在从句中充当主语、宾语、表语或定语。

e.g. That he said so made us angry .

What he said at the meeting made us angry.

China is no longer what it used to be.

八、疑问词 + ever和no matter + 疑问词的区别

1、疑问词 + ever既可引导名词性从句，又可引导让步状语从句。

e.g. Whoever breaks the rule must be punished.

Whoever breaks the rule, he must be punished.

2、no matter + 疑问词只能引导让步状语从句。

e.g. No matter who breaks the rule, he must be punished.
