定语从句
The engineers made two big plans for the dam,____ was never put in force.
A.one of them B.which C.one of which D.every one of which
问题在于C和D 由于从句用的是was 我就选的D在我看来选C 的话which指plans 从句应该用were 而D选项解决了这点 可是答案是C
答
C是对的,one of which中one是中心词,决定单复数,every one一般不用在两者之间撇开这题不说 ，主谓一致的话one of the plans______ never put in force 空里应该填were吧还有个问题，假若有个选项，each of which 是对的吗填was
