I was dong my homework at nine o’clock yesterday

题目

I was dong my homework at nine o’clock yesterday
能改成I did my home work at nine o’clock yesterday吗,是不是加了时间点就必须要用过去进行时除了能瞬间完成的动作以外的?

答案

同学,是不是你写错句子啦啊,应该是：“I was doing my homework at nine o'clock yesterday”而且这是肯定不能改的啊,因为此为一个过去进行时态的题,已经指明了过去的具体时间,就一定是进行时态!
