问题
The rescue team must have searched for the missing visitors in the earthquake two days ago, ______?
选项
A、mustn’t they
B、haven’t they
C、didn’t they
D、hadn’t they
答案
C
解析
本题考查反义疑问句。如果陈述部分含有表推测的情态动词must,其反问部分应根据具体情况而定。must表示推测,其简短疑问句部分必须与must后面的主要动词相呼应。对过去发生的动作或存在的情况推测时,若表示肯定,则用haven’t或hasn’t;但如果句中有表示过去的时间状语,如yesterday,two days ago等时,则用didn’t;若表示否定,其否定式通常不是must not,而是can’t(cannot)。本题中是对过去的肯定推测,有一个表示过去的时间状语two days ago,因此应当用didn’t they。
