B

题目分析：句意：--和骑自行车相比，你更喜欢游泳吗？--我宁愿骑自行车而不是游泳。 prefer A to B 比起B来更喜欢A, ,prefer doing A to doing B,和做B相比，更喜欢做A， prefer to do rather than do 与其……不如……，would rather可以与than连用，构成“would rather do +than+do”结构。e.g. Tom would rather read than talk．="Tom" prefers reading to talking．汤姆喜爱读书胜过与人交谈。因此选B正确。

考点: 考查非谓语动词的用法。
