题目内容

4．The boy with two dogs ______ in the yard when the earthquake rocked the city．（　　）

A．

is playing

B．

was playing

C．

are playing

D．

were playing

分析当地震使那个城市震动的时候，那个男孩正在和两只小狗在院子里玩．

解答答案：B．
根据when引导的时间状语从句用了一般过去时，判断设空处的动作"玩"在过去的某个时刻正在进行着，且是一段时间内持续进行，所以用过去进行时，过去进行时的构成是：主语+was/were+动词的现在分词；主语后有with构成的短语修饰时，谓语动词仍与短语前的主语保持一致，本句的主语是the boy，是第三人称单数，所以be动词用was，play的现在分词是playing；故选B．

点评本题考查了动词的时态．做题时，一定要特别关注有关的时间短语，这是判断句子时态的标志．在没有时间状语的情况下可以联系上下文根据语境来做出正确判断．
