Question

求各位大神一道英语题，就是我很笨啦，麻烦讲详细点，一定要详细点，谢谢了~

______at the result of the experiment,she decided to have another try the next day.
A.Disappointing B.Disappointed C.To disappoint D.To be disappointed

Answer 1

B.
考察过去分词短语作原因状语的用法. 这里的disappointed同时具有了形容词性质.
从句的逻辑主语还是she, 与主句的主语she (decided)一致.
同时考察固定搭配be disappointed at....
该结构可以转换为原因状语从句.
Because she was disappointed at..., she decided to....
太多的不说.

Answer 2

选b 根据大意和后面she decided 语态 其他时态不合适

Answer 3

个人认为选a 语法方面不知道 看到这个问题 也同求人来讲解一下

追问

答案是B
