prep07关于比较的一道题 - ChaseDream

2.Compared to those who do not, running three days a week saves an average of 14.1 percent on health-care costs each year in the UnitedStates.

(A)Compared to those who do not, running three days a week saves

(B)Compared with nonrunners, people who run three days a week save

(C)Compared to not running, those running for three days a week save

(D)When compared with those who do not, people running three days a week save

(E)When compared to nonrunners, running three days a week saves

正确选项B，看起来也是简单明了。

请问各位NN，CD选项有什么致命性的错误嘛?

C: compare to not running, those... 大多数的解释是running和those没办法比较，但是前面的从句有没有可能是compare to people not runinng, those...呢? 因为those只能指代的是前面的同类型的事务，既然用了those前面应该提到了同类型的事务才对。

D: when compared with... people... 这句话也是和B的语义是一样的，具体为什么错了呢？

总结: 如果单纯从简洁度判断的话，B选项是可以被选出来的，但是我想知道有没有其他的致命性错误呢？再次感谢！
