1. Car owners who inflate their tires properly can substantially boost their vehicles’ fuel efficiency, since the increase in car-road friction can waste up to five percent of car fuel by underinflation.
(A) Car owners who inflate their tires properly can substantially boost their vehicles’ fuel efficiency, since the increase in car-road friction can waste up to five percent of car fuel by under inflation.
(B) Because the underinflation of tires can waste up to five percent of a car’s fuel by increasing car-road friction, car owners can substantially boost their vehicles’ fuel efficiency by properly inflating the tires.
(C) Their vehicles’ fuel efficiency is substantially boosted by car owners through the proper inflation of tires that, when underinflated, can waste up to five percent of car fuel by an increase in car-road friction.
(D) The proper inflation of tires by car owners, due to the fact that underinflation can waste up to five percent of a car’s fuel by the increase of car-road friction, can substantially boost their fuel efficiency.（B）
(E) Because up to five percent of a car’s fuel are wasted through the increases in car-road friction when the tires are underinflated, car owners properly inflating tires can substantially boost their fuel efficiency.
Why A is wrong? 而且整个题目也不太知道何从下手。盼望大虾们多多指教。
同问同问
我觉得a似乎是句意不如b不好，car owners who inflate their tires 不如car owners... by properly inflating the tires 好
就能想到这么多了，大家继续讨论啊
顺便寻987和以前各类语法题的对应关系贴，如何才能搜到以前的老贴呢？
四楼的意思是说，把原因放在前面比放在后面好是么?
我觉的A的问题是:the increase in car-road friction 应该是磨损的增加导致油耗上升,还是增加的磨损导致呢
显然没有increasing car-road friction 明确

同意9楼观点，见原885 section 7 第8题
8 The rising of costs of data-processing operations at many financial institutions has created a growing opportunity for independent companies to provide these services more efficiently and at lower cost.
(A) The rising of costs
(B) Rising costs
(C) The rising cost
(D) Because the rising cost（C）
(E) Because of rising costs
这样比较一下就不难理解了
我觉得此句是要说：underinflation 导致了 waste up , 于是做得对的owner可以得意了。 所以整句话的重心应该在 underinflation & inflate上。 B的前半句就选择了underinflation 来做主语。
这题我也选了A,事后比较答案确实B比A好.
1.B通过了两个by+doing结构,明确表达了feul是怎么wast up, 以及car owner如何boost efficiency.
而且又平行.
2.A不如B好,主要在于没有体现动作,而仅仅以结果说明原因.
一家之言.

问题是，大家都没讨论最重要的区别。
是磨损增加使得油耗增加呢，还是轮胎不够气使得油耗增加。这就是A和B的区别吧。
A，increase in car-road friction can waste up to five percent of car fuel by underinflation
B, the underinflation of tires can waste up to five percent of a car’s fuel by increasing car-road friction
我就是这个问题上搞糊涂了。不知道是不是本题考点？除了形式对称外，是不是还在考逻辑意思和关系？
同楼上想法，这是谁是因谁是果的事情，其他判断依据如“since不用来表原因”，"两个by doing平行结构"都不能是考场状态下的主要判断依据吧

此题有两点：
1, 结构，
人不可以直接提高机器的效率，一定 by something A incorrect,
2, increase in car-road friction 强调 friction 的 增加， 难道不增加的 friction 就没问题吗？？
increasing car-road friction
强调是
增加
friction，
我觉得区别在于.
A强调的主要是Car owners can do something. B强调的是by inflating the tires.
这道题的意思应该是说,通过XX方式,可以做到什么. 而不是哪个人可以做到什么.所以选B.
the increase in car-road friction的意思是强调"increase",但是increase本身不能waste fuel,而应该是friction waste fuel
waste up to five percent of a car's fuel by increasing car-road friction是指waste的是增加的friction
应该考的就这个意思吧...我觉的A的问题是:the increase in car-road friction 应该是磨损的增加导致油耗上升,还是增加的磨损导致呢
显然没有increasing car-road friction 明确
分析的很有道理，the increase in car-road friction,强调的是increase；而increasing car-road friction,强调的是friction。代回原句，friction是导致的原因，而不是增加。（大家可以把修饰的部分全部拿掉，然后就能体会出来了）
有收获，顶～
