题目内容
15.___________ in hard seats for 6 hours,we finally stepped out of the train tiredly.( )| A. | Sitting | B. | Having sat | C. | To sit | D. | Sit |
分析 由于坐了6个小时的硬座,我们最后很疲倦地走出了火车.
解答 答案B
由于是先坐了6个小时的火车,然后才疲倦地走出来.所以sit的动作发生在 step out 的动作之前,要用分词的完成式,作时间状语.故选B.
点评 考查分词的完成式.主要要记住分词的动作要早于句子谓语动词的动作,才能用这一时态.而且,分词的完成时一般只作状语,不作定语.
