当句子中有have时，反意疑问句应该怎么改

Question

如题所述

Answer 1

如果have在句子中是作实义动词，那么反义疑问句就应该用do/don't
例如：They have a beautiful house, don't they?
如果have在句子中是作现在完成时的助动词，那么反义疑问句就用 have/haven't
例如：You have finished your homework, haven't you?
如果句子中的结构是情态动词must/might/could/would/will/should/need+have done虚拟形式的话，这个要看情况而定
例如：You look tired. You must have stayed up last night, didn't you?

Answer 2

当一个句子中有have时，反意疑问句应该怎么改？
主要是看have这个词的情况，当 have 是助动词时，其反义疑问句则仍用have.
You have finished the work， haven't you?
当 have 是实意动词意思是”有“的时候， 其反义疑问句则用do.
she has two children，doesn't she?
