题目内容
4.I saw Sam and David in the playground yesterday afternoon.They____games with their classmates then.( )| A. | play | B. | will play | C. | are playing | D. | were playing |
分析 昨天下午我看到Sam和David在操场上,那时他们正在和同学们一起玩游戏.
解答 答案:D.
根据时间状语then结合语境"昨天下午我看到Sam和David在操场上,那时他们正在和同学们一起玩游戏."判断设空处的动作在过去某个时刻正在进行着,且动作在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,主语是they,所以be动词用were,故选D.
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.
