看助动词是什么,就用什么反问,也就是怎么变否定句,就怎么变反义疑问句. He has lunch at school.He doesn't have lunch at school He has lunch at school,doesn't he?（has是示意动词,吃） He is from the USA.He isn't from the USA.He is from the USA,isn't he? He is listening to music.He isn't listening to music.He is listening to music,isn't he? He has been to Beijing.He hasn't been to Beijing.He has been to Beijing,hasn't he?(has是助动词)
