我想要请教一道英语题，很简单的！请各位进来下

C是肯定对的，如果是多选题的话，E也可以选上。
前面的独立结构是从When he was faced with a difficult situation变来的。

E
face with 常用于"sb + be + faced with sth"结构中。如:
The biggest problem facing us /that faces us is pollution.
We are faced with the biggest problem -- polution.
No matter what difficulty we are faced with,we should not give up.

C Faced with a diffcult situation,Aronld decided to ask his boss for advice.
因为如果不倒装,句子是Aronld was faced with a diffcult situation,Aronld decided to ask his boss for advice.

E
动名词做主语，be faced with sth，面临某些事情 。

E
sb be faced with sth
动作的主语都是人，所以是ing 分词
