反义疑问句问题：Poor Tim,he has little money,____ he?
1.Poor Tim,he has little money,____ he?
2.His sisterhad a bad cough,____?
3.Mary has not come here ,____ she?
4.You have seen this movie,____ you?
我不明白为什么4.要填 haven't,可第一题却要填doesn't,老师说have是助动词,可has为什么不是?

1Doesn't. 2 did she? 3has 4haven't
第一题的has是实意动词,有具体意思,表示意思为 有.所以反问疑问句要用does.
而第四题的have是助动词,表示一种时态,没有具体意思.意思是说,你已经看过电影了?这里的实意动词是see而have是助动词,表示完成时态.所以,对于有助动词have的反义疑问句,要用haven't
第二题,她姐姐病了.这里得病中的has是实意动词,所以借助助动词does,又因为是一般过去时,用did
第三题,实意动词是come,have表示完成时态,是助动词,所以最后用has
