Question

问两个问题1.While you were playing tennis,Tony ___(call)应该填什么
2.They ___(arrive) while we were having dinner.这个又该填什么?
用什么时态,为什么?

Answer 1

While you were playing tennis,Tony called.你们在打球的时候Tony打电话来了,you were playing tennis是过去进行时,Tony打来电话是一般过去时.

They arrived while we were having dinner.我们正在吃晚饭的时候他们到了.we were having dinner是过去进行时,他们到达就是一般过去时,arrive没有进行时,要么到了要么没到.

这两句是同一个语法,当a在干什么的时候,b正好做什么,吃饭、打球是过去进行状态,打电话、到达都是一般过去时.
