啥时候用do提问啥时候用is？我看网上说有谓语动词就用可是又看好像不是不很确定啊.求专业人士解答！！

Question

如题所述

Answer 1

一般现在时的疑问句中,如果有be动词（am,is,are),则用be动词，也就是说，你看句中有没有is，如果有就用is。没有be(am, is, are)的时候，也没有情态动词can,may,must等时，就用助动词do,does帮助提问。
例如：She is Jane. 疑问句：Is she Jane?
I am a student. Are you a student?
He plays basketball every day. 疑问句：Does she play basketball every day?
I like English. 疑问句：Do you like English?
They like English. 疑问句：Do they like English?
注：第三人称单数用Does，非第三人称单数用Do ，助动词后面加动词原形。追问

谢谢哦~
