(A) shown that in societies where they consume little salt, their

(B) shown that in societies that have consumed little salt, their

(C) shown that in societies where little salt is consumed,

(D) they showed that in societies where little salt is consumed,

(E) they showed that in societies where they consume little salt, their

这道题选C，别的答案我都知道哪里错了，可是C的都好后边是blood pressure，那就是一个王铮的句子吗？可是都好不能连接两个句子啊，为什么C对？

A,B > 指代错误。 their指代societies错误，“ societies的blood pressure” 逻辑错误。

D,C > 时态错误。 .......and.......结构中and两边的时态要一直，在这里 have linked是现在完成时，所以show应该
用过去分词shown

所以选c
