Question

英语翻译
The report concludes that the special challenge confronting the undergraduate college is one of shaping an “integrated core” of common learning.这里confronting为什么用ing形式?

Answer 1

the special challenge confronting the undergraduate college is one of shaping an “integrated core” of common learning.是conclude的宾语从句.
这个宾语从句的主语是the special challenge, 谓语是is, 表语是one of shaping an “integrated core” of common learning.confronting 是修饰限制主语the special challenge,所以只能用分词,并且两者之间是主动关系,所以只能用ing 分词.
