When I hurried to the station,there happened ____ no bus at that time.选什么?WHY

问题描述:

When I hurried to the station,there happened ____ no bus at that time.选什么?WHY

to be,表示的是碰巧。 happen to do sth, 碰巧做某事。

to固定用法,也有to do ,也有to doing ,都是to

to be这是一个there be句型的变形,happen to do是碰巧的意思,两相综合填to be

此空应该填 to be
基本句型是there be 有 和happen to be 碰巧是 合起来there happen to be 就是碰巧有的意思
这种题就是there be 句型的变形题目
就像there will be 和 there uesd to be 一样的。希望可以帮到你
