标题: [求助] 大全448
大全448 It may someday be worthwhile to try to recover uranium from seawater, but at present this process is prohibitively expensive.

(A) It may someday be worthwhile to try to recover uranium from seawater

(B) Someday, it may be worthwhile to try and recover uranium from seawater

(D) To try for the recovery of uranium out of seawater may someday be worthwhile（A）

(E) Recovering uranium from seawater may be worthwhile to try to do someday

c为什么不对?是因为recover from 而不能用out of 么?如果将out of 改为from,是不是就正确了呢?

recover from是固定搭配。

即便是recover from, C仍然错误。首先，动名词作主语很罕见，OG里几乎没见过。其次，OG认为trying to表示名词是错的。参见OG 6的解释:

Although an “-ing” verb such as trying can sometimes be used as a noun, the phrase the organism’s trying to metabolize in A is unidiomatic because trying is used as the object of organism’s.

PS. 请mm下次发帖把题号加到标题，以方便后人检索。谢谢！我编辑了一下您的帖子，加上了题号。
