找了一些资料 发现这个比较简便 不用看得你那么烦 一、当陈述句部分有否定词(never,no,nobody,seldom,nothing,nowhere等)时,反意疑问句要用肯定形式。如:He seldom goes home on Sundays,does he?二、当陈述句为祈使句时:①如果是肯定陈述句,反意疑问句常用won't you/will you?如:Do exercises more carefully next time,won't you/will you?②如果是否定陈述句,反意疑问句通常只能用will you?如:Don't do things at the wrong time,will you?③如果陈述句以Let's开头,反意疑问句用shall we?如:Let's visit the High Dam,shall we?④如果陈述句以Let us开头,反意疑问句用will you?如:Let us go hunting,will you?三、当陈述句中有used to时,用did或used构成反意疑问句。如:He used to be a famous writer,usedn't he/didn't he?四、当陈述句有ought to时,用ought或should构成反意疑问句。如:He ought to be praised for what he has done,oughtn't he/shouldn't he?五、当陈述句中含有must时,反意疑问句可有多种构成形式:①表示推测时,反意疑问句的构成形式举例如下:He must be a visitor,isn't he?(对现在情况的推测) You must have seen him at his birthday party yesterday,didn't you?(对过去情况的推测,且句中有过去的时间状语) You must have seen him at his birthday party,haven't you?(强调动作的完成) ②表示"必须"或"必要"时,其反意疑问句的构成举例如下:They must work hard,mustn't they?(必须) They must take medical lessons,needn't they?(必要) 六、当陈述句中有dare,need时,如果是情态动词,用dare,need本身构成反问,如果是实义动词,则用do的适当形式。如:He dare climb the mountain,daren't he?She dared to walk at night,didn't she?You need have a rest,needn't you?The house needs to be cleaned,doesn't it?参考资料：
