What can be done to help people with eye problems?They can be
A.operated on B.do operations C.performed operations D.cure or treat for free
要理由
答
A.operated on
operate on sb 给.动手术
为什么不用cure or treat for free1. 首先,这是被动句,be 动词后要接过去分词, 而cure or treat 是动词原形2. cure 治愈, 强调结果, treat 治病, 强调动作, 这两个放在一起有点不知所云
