Question

The students()at eh way the questions were put,didn't know the answers to them

A.they surprising B.surprised C.their being surprised D. surprise
选哪个请解释

Answer 1

选择B
固定搭配：be surprised at 对....表示惊讶
surprised 已经弱化成形容词形式，已经不是surprise的被动结构，过去分词形式
The students（who were）surprised at the way the questions were put, didn't know the answers to them.
形容词结构作后置定语，可以理解为省略定语从句的引导词和be。
句意：学生们惊讶于问题被提出的方式，不知该如何回答。

Answer 2

这个应该选b。因为在这里是过去分词做定语。转换成定语从句是这样的。
the students who are surprised at the way… =the students surprised at the
way…
