Question

【题目】—Why do you look worried?—There are so many problems __________.

A. remaining to settle

B. remained settling

C. remaining to be settled

D. remained to be settled

Answer 1

【答案】C

【解析】第二句话的句意：还有许多问题有待解决。remain是不及物动词，没有被动形式，故排除B、D两项；problems与settled 成被动关系，remain后面接不定式时须用不定式的被动形式,故C项正确。
