1.have若为助动词（完成时）：肯定句的反问：haven't,hasn't hadn't
否定句的反问：have..has..had...
have若为实意动词：肯定句的反问：didn't doesn't don't
否定句的反问：did..does..do..
2.will you
省去主语的祈使句的反意疑问句,疑问部分用will you.
Don't do that again,will you?
Go with me,will you / won't you
3.do you
反意疑问句的陈述部分为非第一人称主语+ think(believe,suppose,consider) + that从句时,问句部分的动词和主语与陈述部分的主句动词和主语保持一致.如：
①They all think that English is very important,don’t they?（不用isn’t it?）
②He didn’t think that the news was true,did he?（不用wasn’t/ was it?）
4.will it
反意疑问句的陈述部分为I(We) don’t think(believe,suppose,consider)+ that从句时,从句为否定意义,问句部分的动词和主语仍与that从句保持一致且用肯定式.如：
①I don’t think that you can do it,can you?（不用do ）
②We don’t believe that the news is true,is it?（不用do we?）
5.当陈述部分的主语是everyone,everybody,someone,nobody,no one,none,anyone,somebody等合成不定代词时,在非正式文体中,附加疑问句中的主语通常用he或they.例如：
Someone opened the door,didn't he/they?有人开了门,是不是?
Nobody went to the cinema,did they?没人去看电影,是吗?
当陈述部分的主语是everything,nothing,something,anything等合成词,附加疑问句中的主语用it.例如：
Nothing serious happened,did it?什么事情也没有发生,对吗?
Everything is ready,isn't it?一切准备就绪了,不是吗?
你需要找本语法书,好好看看反意疑问句!
