疑问代词有who,whom,whose,what和which等。在句子中用来构成特殊疑问句。疑问代词都可用作连接代词,引导名词性从句(主语从句、宾语从句和表语从句)

如:Tell me who he is.告诉我他是谁。

2)疑问代词的用法

疑问代词主要用来构成特殊疑问句的。用法如下:

1. 作主语

What has happened?who did it ?发生了什么? 谁干的?

2. 作宾语

What did you want?你想要什么?

which of these stories do you like best?这些故事你最喜欢哪个?

3. 作宾语

Whose dictionary is that ?这是谁的字典?

说明1:

which 和 what 所指的范围不同。what所指的范围是无限的,而which则指在一定的范围内,例如:

Which girls do you like best?

你喜欢what 哪几个姑娘?

What girls do you like best?

你喜欢什么样的姑娘?

说明2:

Whom是who的宾格,在书面语中,它作动词宾语或介词宾语,在口语中作宾语时,可用who代替,但在介词后只能用whom, 例如:

Who(m) did you meet on the street?

你在街上遇到了谁?(作动词宾语)

Who(m) are you taking the book to?

你要把这书带给谁?(作介词宾语,置句首)

To whom did you speak on the campus?

你在校园里和谁讲话了?(作介词宾语,置介词 后,不能用who取代。)

说明3:

疑问代词还可引导名词性从句,例如:

I can't make out what he is driving at. 我不知道他用意何在。

Can you tell me whose is the blue shirt on the bed? 你能告诉我床上的蓝衬衣是谁的吗?

Much of what you say I agree with, but I cannot go all the way with you.你说的我大部分同意,但并不完全赞同。
