[求助] 大全446的C项错在哪里?

446.        It may be another fifteen years before spacecraft from Earth again venture to Mars, a planet now known to be cold, dry, and probably lifeless.

(A) again venture to Mars, a planet now known to be

(B) venture to Mars again, a planet now known for being

(C) will venture to Mars again, a planet now known as being

(D) venture again to Mars, a planet that is known now to be

(E) will again venture to Mars, a planet known now as being

答案是A项. 恰恰是我觉得最不可能正确的....但是C项错在哪里呢? known as...和known to do都是固定搭配吧

请指教.

as being就已经是错的了。所有的as being都可以省略为as. 这里不能用as, cold, dry and lifeless都是形容词。known as后面一般跟名词。就算有形容词也是形容后面出现的名次。

原来spacecraft是单复数同型，这个真的从来都不知道。

所以我第一步就把A排除了。
