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?

Which do you prefer, coffee or tea? 咖啡和茶,你喜欢喝哪种?

What do you usually drink before dinner? 你饭前通常喝什么?

Who(m) did you meet on the street?你在街上遇到了谁?(作动词宾语)

Who's not here today? 今天谁没来?

Which pen is red? 哪枝钢笔是红色的?

一般说来,特殊疑问句都要读成降调() ,并往往让最后一个单词承担此重任。如:
