Ron对they和their的解释： yeah. i don't think that pronoun ambiguity is the criterion here. 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.

At any time用法未排除這個時候

应该是用any other time区分时间

现在生产的车和以前生产的车不是同一种车啊不能they！Their！

any time 没有排除现在

应该是车比车，而不是现在的车（同一辆车）比以前省油

看到they 直接杀 不可以指代前文的，自己和自己还比较个鸟？？？

they 应为those，否则指代的是同一批车； at any time 没有排除自身； their 指代不明
elaine_yin627 2016-05-06 22:00:32
they 只能指和之前完全一样的，和之前同一类不完全一样就是用those。

they指代同一个，而those指代的是新的copy，此处应该是those

they 精确指代前者

比较的时候不要用it和they they/their 指代时指代的物体是完全同一个物体（比较的情况只能是比较同一个物体在不同环境或时间状态下的区别）。就这道题而已they指代“现在技术下生产出来的汽车”，所以“现在的汽车”比“现在的汽车”的产品历史上更省油，显然不合逻辑。

比较的时候不要用it和they为什么我就是记不住呢！
