大全875、359 介宾短语的比较

875.                 Today’s technology allows manufacturers to make small cars more fuel-efficient now than at any time in their production history.

(A) small cars more fuel-efficient now than at any time in their

(B) small cars that are more fuel-efficient than they were at any time in their

(C) small cars that are more fuel-efficient than those at any other time infficeffice" />

(D) more fuel-efficient small cars than those at any other time in their（C）

(E) more fuel-efficient small cars now than at any time in

为什么E，介宾语短语比较不对？

下面这题，比较介宾短信就对呢：

359.         In 1990’s, there are more babies born by women over thirty years old than under it.

(A) than under it

(B) than were they under it

(C) than had been under it

(D) than were the babies（A）

(E) than those were under it

875,C是正确答案，但是those仍然可能指代manufactures或small cars.

如何判断呢？请NN指点迷津。

make sth.是可以的。They make cars。 that是定语从句。

问题是C的those指代谁？

875的E的问题就是歧义，是“数量多了”还是“更省油了”搞不清楚

359的E的问题是要想正确表达需在those前补上by

请指正，谢谢
