选Bwould rather后面直接加动词是加动词原形，但该题would rather 后面还跟了sb，所以应看成would rather sb did的句型，表示主语宁愿让某人干某事。这时，从句谓语动词要用虚拟语气，即用一般过去时表示过去现在或将来要做的事；用过去完成时表示过去要做的事。如：I’d rather you met her at the airport tomorrow morning. 我但愿你明天早上能在机场见到她。该题还原为陈述句语序为“You would rather who helped you repair your CD player”，意为“你想要谁帮你修cd机？”
