EG1:She was playing with ther friends when the babysitter arrived.
EG2: She played with ther friends when the babysitter arrived.
解释如是说:
第一个句子中,she was playing表示背景动作,发生在arrived之前。我是这样理解的:babysitter来的时候,she正在playing,那么play的动作已经开始了,那么play发生在arrived之前;
但是第二句中,"In second case, the acion played took place after the babysitter arrived. Both actions are in the simple past and express equal levels of importance.
