说明1:
无论是做疑问代词还是限定词,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:
疑问代词用于对介词宾语提问时,过去的文体中介词和疑问代词通常一起放在句首,现代英语中,疑问代词在句首,介词在句未,例如:
For what do most people live and work?
大部分人生活和工作的目的是什么?(旧文体)
What are you looking for?
你在找什么?(现代英语)
说明4:
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。
3)疑问代词用于特殊疑问句中,疑问代词一般都放在句首,并在句中作为某一句子成分。如:
①What is this? (what作表语)这是什么?
② Which is bigger, the left one or the right one? (which作主语)哪一个大一点,左边的一个还是右边的一个?
③What are you talking about? (what作宾语)你在说什么?
④Who will go with you? (who作主语)谁和你一起去?
⑤Whom are you talking to? (whom作宾语)你在跟谁说话?
⑥Whose dictionary is this? (whose作定语)这是谁的字典?
●which表示在一定数目(或范围)之内的选择,what则没有这种限制。
如:
①Which do you prefer, coffee or tea? 咖啡和茶,你喜欢喝哪种?
②What do you usually drink before dinner?
你饭前通常喝什么?
4)疑问代词可以引导主语、宾语、表语从句等。
疑问代词本身在从句中担当一定的句子成分。如:
①Who will attend the meeting is still not decided。
谁出席这个会议,现在还没有决定。
(疑问代词who引导一个主语从句,它本身又在从句中作主语。)
②Do you know which grade she is in?
你知道她上几年级了吗?(疑问代词which引导宾语从句,它本身在从句中作定语。
)
③What he says sounds true。
他讲的话听起来很对。(疑问代词what虽然相当于all that,它引导一个主语从句,但它本身作从句的宾语。)
④What his name is remains unknown。
还没有人知道他叫什么名字。(疑问代词what引导主语从句,what在从句中作表语)。收起
