哪位大虾可以讲一下than后的those什么时候可以省略（甚至身略了更好），什么时候没有those就是不可比要排除了呢，比如198那道等等，，，，急，，，，，，，，，

我来说说吧，这道题我选了D，现在我发现D不对的原因有下：

1.more有歧义

more的意思是“更省油的小汽车”还是“更多省油小汽车”？主语是“现代科技”，根据可能更合理推测，“现代科技”应该推动的是前者。

2.their指代不清

指代的是“manufacturers”还是“cars”阿？——不清

以下是引用upup在2006-4-25 23:11:00的发言：

112. Domestic automobile manufacturers have invested millions of dollars into research to develop cars more gasoline-efficient even than presently on the road.

(A) into research to develop cars more gasoline-efficient even than presently on the road

(B) into research for developing even more gasoline-efficient cars on the road than at present

(C) for research for cars to be developed that are more gasoline-efficient even than presently the road

(D) in research to develop cars even more gasoline-efficient than those at present on the road（D）

(E) in research for developing cars that are even more gasoline-efficient than presently on the road

Choice D, the best answer, uses the preposition than to compare two clearly specified and grammatically parallel terms, the cars the manufacturers hope to develop and those at present on the road.
                    In A, the phrase more gasoline-efficient... than presently on the road does not identify the second term of the comparison. In B, the misuse of modifying phrases produces an ambiguous and awkward statement: even more gasoline-efficient cars could refer either to more cars that are efficient or to cars that are more efficient. Choices B, C, and E all use research for [verb] where the idiom requires research to [verb]. In addition, C awkwardly separates even from more, and C and E again fail to indicate the second term of the comparison.

所以gwd这题A应该是错的。

我只是越来越不明白，THAN什么时候做关系代词，什么时候做连词啊？？？？？

Q30:

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

1. small cars more fuel-efficient now than at any time in their
2. small cars that are more fuel-efficient than they were at any time in their
3. small cars that are more fuel-efficient than those at any other time in
4. more fuel-efficient small cars than those at any other time in their
5. more fuel-efficient small cars now than at any time in

小女公子引用的这个OG题目很能说明问题，这一点正是大家在讨论中忽略的一点，...than....前后应对称且有可比性的，cars能和at any time相比吗？不能，cars 只能和those(指代cars)相比较且平行对称，这样A,B,E均可排除，剩下D,C，用楼上多次提到的more fuel-efficient cars会引起歧义就能得出正确答案是C.

今天研究这套题，此题与OG112是有区别的

此题A。small cars more fuel-efficient now than at any time in their 是2个时间状语比

112(A) into research to develop cars more gasoline-efficient even than presently on the road than前面没有时间状语，才会出现比较不一致的问题

这一题A中是时间问题，B中的they是不可以用来指代非生命物体的，曼哈顿讲过。因此就是C

另外，prep给出答案为C，莫要继续纠结

the sentence is supposed to say that today's small cars are more fuel-efficient than previous small cars -- i.e., OTHER small cars.
this is important, because you can't use a "they"/"their" construction (which would illogically imply that you're talking about the same small cars mentioned in the first part of the sentence).
the use of "those" in (c), on the other hand, accomplishes this distinction nicely.

analogy:

sprinters in texas can run faster than they can in north dakota.
--> illogical; in this sentence, "they" would be taken to mean "sprinters in texas" (i.e., not just sprinters).

sprinters in texas can run faster than those in north dakota.
--> makes sense; "those" = sprinters, in this case.

same thing with "they/their" vs. "those" in these instances.
