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?
