(A) associated with other calves, they will require less medication and gain weight quicker than do (B) associated with other calves, they require less medication and gain weight quicker than (C) associate with other calves, they required less medication and will gain weight quicker than do (D) associate with other calves, they have required less medication and will gain weight more quickly than do (E) associate with other calves, they require less medication and gain weight more quickly than 答案是E，我觉得E还成，因为符合对称的比较结构，但是，为什么主句用SHOWED THAT，从句却用现在时态呢？疑惑啊！！！好象一般而言，GMAT规则是要求从句时态与主句时态相一致啊！！！ 作者: braveMBA 时间: 2003-11-5 07:08
关键是associate和require 的时态对应，这是相关联的内容。 showed 可以不同，因为可以是以前的研究所阐明的一个事实，这个事实今天依然成立。
