为什么最后用had fallen 过去完成时,而不用过去式?
When I CAME back into the house,it was raining (去more)harder and harder.Then I heard a loud crashing sound from (去the)back of the house.When I ran out to find out WHAT had happened,a big tree had fallen down and BROKEN the top of the backroom.

ran已经是过去式了,倒了发生在ran的前面,过去的过去用had done
因为最后表过去已经完成过了,用我们老师教的话说:老祖宗传下来的,只要记住就行。
