选择题 _______such a difficult problem, he didn't

选择题 _______such a difficult problem, he didn't know what to do. A.Faced B.Facing C.Faced to D.Facing with 每个选项都有面对的意思，为什么选B

Answer 1

首先，“面对”这个困难的问题是人主动面对，所以A、C先被排除（过去分词表被动的），其次face是及物动词，后面可不加介词直接加宾语，所以选B

Answer 2

选择题 _______such a difficult problem, he didn't know what to do.
A.Faced B.Facing C.Faced to D.Facing with 每个选项都有面对的意思，为什么选B

因为Facing such a difficult problem, he didn't know what to do. =When he faced such a difficult problem, he didn't know what to do.
选项A和C是过去分词，表被动，此句的逻辑主语是人he，选项D介词搭配错误。

Answer 3

B

face 面对，现在分词做伴随状语。
面对如此的难题，他束手无策。

Answer 4

B，伴随状语

Answer 5

我只知道开头有些要加ing、句式反过来看也可以进行判断
