I was reading the paper____she was writing.
A.when B.as C.while D.after
老师你说,表示过去发生的事情,while 引导的时间状语从句与主句可以同时用过去式或过去进行时,意思上没有多大的差别。 如:
I cooked the dinner while he played the piano.
= I was cooking the dinner while he was playing the piano.
他在弹钢琴,我在做饭。
但是表示过去发生的事情,as也可以引导的时间状语从句与主句可以同时用过去式或过去进行时。 如书上一句话:
As they walked along,the students sang happily.
那上面一道题选B也可以?
