反义疑问句是高中非常重要的英语语法知识,由于反义疑问句复杂多变的形式和不同常规的回答,让很多考生视为难点。其中尤以must反义疑问句(must出现在反义疑问句的陈述部分)最为复杂。其实must反义疑问句只有以下三种情况,掌握must反义疑问句三种情况就能轻松对付考试。

must的三种反义疑问句形式

(1) must出现在肯定陈述句中,表示"必须"的意思,此时疑问部分通常用"needn't"。

例句1:You must take off your shoes when getting into the room, needn't you?

进入房间时你必须要脱掉鞋子,不是吗?

例句2:You must stay here and return the purse to the owner, needn't you?

你必须呆在这把钱包交还给失主,不是吗?

(2) must表示"必须"出现在否定陈述句中(即陈述部分用到must not或者mustn't,意思为"不允许,禁止"),此时疑问部分通常用"must"或者用"may"。

例句1:You mustn't trample on the grass, must you/may you?

你不能践踏草坪,对吧?

例句2:You mustn't smoke in public places, must you/may you?

你不能在公共场合抽烟,对吧?

(3) must出现在陈述部分作为一种肯定的推测,表示"一定,肯定"的意思,此时疑问部分需要根据实际语意来确定。

例句1:He must be angry, isn't he?

他肯定生气了,对吗?

例句2:You must be hungry, aren't you?

你肯定饿了,对吧?

例句3:She must have got married, hasn't she?

她肯定已经结婚了,对吗?

注释:本句中"she must have got married"是对"she has got married"的肯定性强调,所以反义疑问句应该用"hasn't she"。

例句4:You must have finished your job yesterday, didn't you?

你肯定昨天就已经把工作做完了,对吗?

注释:本句中"You must have finished your job yesterday"是对"you finished your job yesterday"的肯定性强调,所以,反义疑问句应该用"didn't you"。
