疑問代詞在句中起名詞詞組的作用,用來構(gòu)成疑問句。疑問代詞有下列幾個:
指人:who,whom,whose
指物:what
既可指人又可指物:which
疑問代詞在句中應位于謂語動詞之前,沒有性和數(shù)的變化,除who之外也沒有格的變化。what,which,whose還可作限定詞。試比較:
疑問代詞:Whose are these books on the desk?
桌上的書是誰的?
What was the directional flow of U. S. territorial expansion?
美國的領(lǐng)土擴張是朝哪個方向的?
限定詞:Whose books are these on the desk?
桌上的書是誰的?
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東的大部分土地歸屬于美國?
說明1:
無論是做疑問代詞還是限定詞,which 和what 所指的范圍不同。what所指的范圍是無限的,而which則指在一定的范圍內(nèi),例如:
Which girls do you like best?
你喜歡哪幾個姑娘?
What girls do you like best?
你喜歡什么樣的姑娘?
指人:who,whom,whose
指物:what
