问题 Scientists think ______ helps some trees to conserve water in winter.

选项 A、when losing leaves
B、leaves are lost
C、that losing leaves
D、the leaves losing

答案 C

解析 不定式作主语,表示比较具体的动作,或表示说话者的某种看法;而动名词作主语则表示某个一般性的动作,或表示说话者的亲身经历,如:It would kill him to work like this 24 hours on end.像这样连续24小时不停地工作会累死他的。It would kill him working hard 24 hours on end.连续24小时卖力地工作会累死他的。
