疑问代词_语法技巧

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?

 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)


 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。
