题目

题型：不详难度：来源：

I prefer taking exercise in my spare time ＿＿ healthy.

A．to keep

B．to keeping

C．rather than keeping

D．rather than keep

答案

A

解析

句意：我更喜欢在空余时间做运动来保持健康。to keep healthy做目的状语。本题受思维定势的影响容易选B，prefer doing sth to doing sth,但不合逻辑。
点评：做题时要认真细致，不受思维定势的影响。注意prefer 的用法：prefer A to B 相比于B更喜欢prefer doing to doing，prefer  to do rather than do相比于做某事（后）更喜欢做某事（前）
