题目

It remains_______whether Jim will be fit enough to play in the finals. A
. It remains ______ whether Jim’ll be fit enough to play in the finals.
　　A. seen B. to be seen
　　C. seeing D. to see

答案

B. to be seen
remain 后一般跟不定式,此处是it 作形式主语,whether 从句作真正主语,"这件事有待观察",故不定式要用被动语态.
句意: 吉姆是否适合参加决赛,还有待观察.
