问题描述：
Seeing him rush into the room with tars in his eye,I asked him what____.
A.would happen B.had happened C.happened D.was happened
那位同学可以告诉我这道题的“知识点”和“考点”.
最好详细一点
答
B
主要考 过去完成时
前面说明的是一个事实,伤心的流泪,说明一定已经发生了什么,所以用过去完成来提问
Awould happen将来时态,冲突
Chappened一般过去时,没有突出已经的重点
Dwas happened 被动过去式,事情自己可以作主语,不需要被动可以把B解释一下吗？谢谢。
