一、疑问词只能用来构成特殊疑问句,它们只有两类:
1、疑问代词:who (whom,whose),what,which
2、疑问副词:when,where,why,how
二、情态动词属于动词类.动词有实意动词(包括系动词、行为动词)、助动词和情态动词,因此情态动词不是疑问词.
三、你这个问题应该这样提:情态动词能够提前构成一般疑问句吗?
回答是肯定的.一般疑问句的结构顺序有三类:
1、系动词提前:be + 主语 + 表语,如:
Is he a worker?他是工人吗?
Are you still here?你还在这里吗?
2、助动词提前:助动词 + 主语 + 谓语动词,如:
Do you go to school every day?你每天都上学吗?
Is she doing housework now?她现在正做家务活吗?
Have you been to Beijing?你去过北京吗?
(注:助动词有四种:do(does),did;have(has),had; be(is/am/are,was/were); will,/would)
2、情态动词提前:情态动词 + 主语 + 动词原形,如:
Can you tell me the way to the bus stop?能告诉我去公交车站的路吗?
May I come in?我可以进来吗?
注:情态动词有:can/could,may/might,must,shall/should,will/would,ought,dare,need
因此,情态动词提前后可以构成一般疑问句.
