Question

--- I spent two weeks in London last summer.

--- Then you must have visited the British Museum during your stay, _______ you?

A. mustn’t            B. haven’t

C. didn’t            D. hadn’t

Answer

C

【解析】

试题分析：题意：逗留伦敦期间肯定去看过大英博物馆。题中last summer表示的是一个确定的过去时间，可认定must have visited是对“过去”的推断。故C项正确。

考点：考查情态动词的推断用法。

【名师点睛】本题考查特殊反义疑问句。A、B选项都是干扰选项，考生要注意调动知识储存来判断，没有A这种反问形式。这里结合情态动词考查反义疑问句，有两点注意：1、陈述部分有must 的疑问句，疑问部分根据实际情况而定。如：He must be a doctor, isn't he? /You must have studied English for three years, haven't you? didn't you?/He must have finished it yesterday, didn't he? 2、 带情态动词dare或need的反意疑问句，疑问部分常用 need (dare ) +主语。如:We need not do it again, need we ?/He dare not say so, dare you?当dare, need 为实义动词时，疑问部分用助动词do + 主语。如：She doesn't dare to go home alone, does she?根据第一个知识点可以选出正确答案。
