一道英语语法题,语法老师请进,
1.Joe and Bob were the only other people who knew the secret _____ their wives.
A.and did not even tell B.who did not tell
请问为什么呢?那么 B为什么不对呢?

答案

who knew the secret _____ their wives已经是修饰the only other people如果再加 who 有点无谓了,而且在意义上,也是不通的 knew the secret和did not even tell their wives两个动作之间存在着先后关系,更含有递进...
