问英语反义疑问句英语高手来He must be Peter Lee,

He must be Peter Lee,____isn't he _____?He must have seen the movie,____hasn't he______?He must have seen the movie yesterday,__didn't he_____?must表示“肯定”的意思时,它的反义问句尾句不能再用情态动词,而是根据must后的动词时态来决定.如果有过去时间状语,就是一般过去时.It is unfair,___isn't it_____?(否定前缀不是否定词,所以还是用否定）（类似：unhappy,unable,impossible等）======以下答案可供参考======供参考答案1:He must be Peter Lee,___isn't he______?因为主句中出现be动词，从句意来看，应该对be进行反义改变。He must have seen the movie,__hasn't he________?同上。He must have seen the movie yesterday,__hasn’t he_____?同上。It is unfair,__isn't it______?同上。供参考答案2:musn't hemusn't hemusn't heisn't it原句为肯定句，末尾是：谓语（否定）+主语（代词）原句为否定句，末尾是：谓语（肯定）+主语（代词）供参考答案3:isn`t hehasn`t hedidn`t heisn`t it

和我的回答一样，看来我也对了
