  参考答案:

  1. 答案:B  解析:the rich 、the poor 是the rich people 和the poor people 的缩略形式,是形容词当复数名词用,故谓语动词用复数。再如:The wounded were all healed because of excellent medical care.

  2. 答案:B  解析:“过去应该做而未做的事”用should have done 这种属于虚拟语气的形式,如:His father died. He thought that he should have done more for him while he was alive.

  3. 答案:D  解析:ought to 比should 语气强。ought to (should) have done 表示“过去本该做而未做”。因为是被动的意思,所以加上been 。如:He arrived late, but he ought to(should)have come earlier. /He ought to(should)have been made to finish his work but he left without telling anybody.

  4. 答案:C  解析:must have done sth. 表示“比较准确地猜测过去某事”的意思,如:There is something wrong with her voice. She must have sung too many songs yesterday evening.

  5. 答案:C  解析:be able to do sth.是“有做特别或具体某事的能力”的意思。can 只表示一般的能力。例如:He could swim but was not able to swim hundred thousand meters.
