答案是surprising 为什么surprise 不行

Gelidjelly

surprising和surprised都是由surprise变换而来的，前者有主动含义，后者有被动含义，surprising的主语通常是物，而surprised的主语通常是人。Be surprised at + n. (v. + ing) 对……感到惊讶，be surprised后还可接不定式和that引导的从句。例如：
(1) The news from the girl is very surprising. She said that dull film was interesting.
从那个女孩那儿得来的消息非常令人吃惊。她说那个无聊的电影很有趣。
(2) The students were very interested in dinosaurs when they visited the museum. They were surprised at seeing the teacher in front of them. Do you know why they surprised to meet their teacher in the museum?
学生们在参观博物馆时对恐龙很感兴趣。他们很惊讶地看见老师就在他们前面。你知道在参观博物馆时，为什么他们对遇见老师感到很惊讶吗？
