一般疑问句是用Do ,Does还是Is,Are,怎么区分
如果句子中有am,is,are,只要把它们提到句子开头就可以了。如果没有am,is,are,是第一或第二人称或复数的句子用do,是第三人称单数的句子用does开头。
例如,she is a student,这样主语后面是be动词的陈述句,改为一般疑问句就只用把be动词提前,改为Is she a student?
如果是She has a bag,这样主语后面不是be动词的句子,改成一般疑问句就在主语前面加上do或does,如Does she have a bag?
扩展资料
最常用的助动词有:be, have, do, shall, will, should, would,did,
助动词协助主要动词完成以下作用:
1、表示时态,例如:
He is singing.他在唱歌。
He has got married.他已结婚。
2、表示语态,例如:
He was sent to England.他被派往英国。
3、构成疑问句,例如:
Do you like college life?你喜欢大学生活吗?
Did you study English before you came here?你来这儿之前学过英语吗?
4、与否定副词not合用,构成否定句,例如:
I don't like him.我不喜欢他。
5、加强语气,例如:
Do come to the party tomorrow evening.明天晚上一定来参加晚会。
He did know that.他的确知道那件事。

或相应过去式)、情态动词(can
