当陈述句部分有情态动词must时,反意疑问部分有四种情况
(1)must表示“必须、禁止“时,反意疑问部分要用must (mustn’t) .
例 You mustn’t stop your car here,must you?你不能把车停在这地方,知道吗?
(2)must表示“有必要”时,反意疑问句部分要用needn’t.
例 They must finish the work today,needn’t they?他们今天必须要完成这项工作,是吗?
(3)当must用来表示对现在的情况进行“推测”时,反意疑问部分要根据must后面的动词采用相应的形式.
例 He must be good at maths,isn’t he?他数学一定学得很好,是吗?
(4)当must用来表示对过去的情况进行“推测”(must + have done)时,如强调对过去情况的推测(一般句中有过去的时间状语),反意疑问句部分要用“didn’t + 主语”;如果强调动作的完成(一般没有过去时间状语),反意疑问句部分要用“haven’t / hasn’t + 主语”.
例 She must have read the novel last week,didn’t she?她上星期一定读了这本小说了,是吗?
You must have told her about it,haven’t you?你一定把这事告诉她了,是吗?
