题目详情
You look very tired and you must have been preparing for the coming examination yesterday evening, _________ you ?
A．didn’t you
B．haven’t
C．weren’t
D．hadn’t
题型：单选题难度：中档来源：不详
答案
C
试题分析： 当陈述部分带有情态动词must表示“必须”时，疑问部分用mustn’t。如： You must work hard next term, mustn’t you? I must answer the letter, mustn’t I? 但若表推测这层含义时，不能用must，而要根据陈述部分must之后的动词而定，如果句子中有明确的过去时间，反意疑问部分与must之后的动词有关，不可用haven’t的形式。如： You must have made a mistake, haven’t you? They must have seen the film last week, didn’t they? He must be in the library, isn’t he?故本题中选C. 点评：反意疑问句是高一必修第三单元语法点，对于反意疑问句平时学习中要注意加强记忆各种形式，做到胸有成竹。
