Question

We ____ for tom at ten last Sunday. He often kept us ______.
a. were waiting, waiting b. were waiting, wait c. waited, waiting d. waited, wait 为什么A,考点什么

Answer 1

这里就是因为是时间点,才用进行时的,你要区分,瞬间动词和过去一个时间点的区别.
瞬间动词,是这个动作一瞬间就完成了,所以没有进行时,但是并不代表说,过去一个时间点,不能用延续性动词呀~
过去一个时间点的话,那么如果是瞬间动词,就用一般过去时,延续性动词就用过去进行时.
希望能解决您的问题.
