史上最难解释的初中英语题

There happened to be a bad flood that year,_____ ?
A：wasn't there B：didn't there C：was there D：hadn't there

首先说明一下这到底是主谓宾结构还是there be 句型。然后选出答案并解释，我已经问了好多人了，都没有令人满意的答案，请高手指点
此题的答案是B选项。我真的糊涂了。此题如果没有be还好说，有了这个词我都不知道是哪个句子结构了。

Answer 1

是there be 结构happened to只是一个插入语,不影响总体句子结构.
所以,选A

Answer 2

我觉得应该是主谓宾结构,there相当于一个地方,答案应该是B

Answer 3

这是 There be 句型， 应该选 A: wasn't there

happen to 可以理解为状语：正巧，如果把它去掉，句子照样成立：

There was a bad flood that year, wasn't there?
那年有一场洪水，是吧？

Answer 4

肯定是主谓宾结构
happen to 如果理解为状语，句子不成立
选B

Answer 5

选A.
happen to作为插入语而已，依然是there be 句型。

there be句型中的谓语动词be被be likely to be，happen to be，seem（to be）， occur等代替，用来描写事物。例如： ]
��There are likely to be more difficulties than they have been prepared for．
��There happened to be nobody in the room.

我问过我外国朋友了,也是个老师,也是说A啊.
