根据语境排除D。
20. 选C。
couldn’t have done sth 结构在此表示责备,指过去本来可以做某事但实际上未做。
第二空填 was wasted,陈述的是过去的一事实。
21. 选B。
根据下文的 I’ll phone the airport and find it out 可知,说话人对自己的推测没有很大把握,故选 might。
若选A,语气太强,不合语境;若选D,不合语法习惯,因为can 表推测通常不用于肯定陈述句中。
22. 选D。
既然“通行证现在不在口袋里”,那么它“掉出去”应发生在过去,故排除A和B。
比较选项C和D所表示的意思,选D更恰当。
24. 选A。
根据 Don’t be so sure 可知前面一空应填must。
第二空填的could表示推测,虽为过去式形式,但表示现在意义,语气较委婉,它与表推测的 can 主要用于否定句和疑问句不同,它可以用于肯定陈述句。
25. 选A。
根据句中有关时态可知“他来”发生在过去,故排除B;根据 I don’t know 可知选项C语气太肯定,不合适;选项D的意思是“本来应该来”,与语境不合。
