中考英语语法专题疑问代词
1、疑问代词在句中起名词词组的作用，用来构成疑问句。疑问代词有下列几个：
指人：who, whom, whose
指物：what
既可指人又可指物：which
2、疑问代词在句中应位于谓语动词之前，没有性和数的变化，除who之外也没有格的变化。what, which, whose还可作限定词。试比较：
疑问代词：whose are these books on the desk? 桌上的书是谁的？
what was the directional flow of u. s. territorial expansion? 美国的领土扩张是朝哪个方向的？
限定词： whose books are these on the desk? 桌上的书是谁的？
what events led to most of the east of the mississippi river becoming part of the united states? 哪些事件使密西西比河以东的大部分土地归属于美国？
3、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？
4、who通常作主语和表语，whom作宾语，例如：
who is to take the chair? 谁做主席？
who is speaking? 是哪一位（打电话）？
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。）
5、whose, what, which这三个疑问代词可以用作：
(1) 主语：
what happened next? 后来怎么样了呢？
whose is better? 谁的好一些？
which is yours? 哪是你的？
2) 表语：
what’s your father? 你父亲是干什么的？
whose is it? 这是谁的？
they are so alike, you can’t tell which is which. 他们是那样相像，你都分不出谁是谁了。
(3) 宾语：
what do you mean? 你是什么意思？
which do you prefer? 你愿意要哪一个？
whose are you going to borrow? 你预备借谁的？
(4) 定语：
which train will you take? 你搭哪一班火车？
what time shall we meet again? 我们什么时候再碰头？
whose umbrella is this? 这是谁的雨伞？
6、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。
