1 答案：C
翻譯：男孩們看起來很高興,我想他們一定贏了比賽
分析：這是對過去事情肯定的推測,使用must have done 這個句型,
2 答案：A
翻譯：你不可能上周五在Jane的辦公室見到她,她已經(jīng)出城兩個禮拜了
分析：這也是情態(tài)動詞用于推測的用法,Mustn't 否定形式不是表示推測,而是禁止的意思,淘汰B,wouldn‘t這是表示對將來事情的推測,這里用的是完成時,而且是last Friday,所以不是對將來的推測,而是對過去的猜測,淘汰C,D 不應(yīng)該,用在這里不合適,因為已經(jīng)出城兩周了,所以是絕對不可能的.淘汰D
ps：對于猜測表示有把握否定的猜測,不用mustn't,用can’t或者couldn‘t
3 答案：C
翻譯：他說他不能辨別出正確與錯誤的區(qū)別
分析：這里表示的意思是能與不能,因此淘汰BD,因為前面使用的是said過去式,因此,這里也該使用can的過去式could,淘汰A
should,must ,would,could,might這幾個詞怎么區(qū)分呀?
should,must ,would,could,might這幾個詞怎么區(qū)分呀?
