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 in

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

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

答案是C，我选了A，解释说的不太清楚，A是不是对比对象不一致？如果A后面than those也加个those这样可以吗？谢谢~

修饰成分无明显原因不能随意省略添加和改变
D,Emore位置改变改变句子意思，排除D,E
A,B,C纵向比较，寻找差异，差异即为考点
发现A,B有个their，C没有
往前找原句中有两个复数名词，manufacturers，和 small cars
their指代不明，排除A,B
答案C

其实冷静下来看，A,B的错误还挺多的
比较是切忌将自身排除在外，可A,B使用any time，没用any other time显然不对
