199. 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.fficeffice" />

(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 underinflation.

(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.

请问这样的题目有没有什么解题技巧，如何迅速排除几个选项？E错在哪里？

谢谢了！

B ？先确认一下答案吧。

jediming · 发表于 2004-3-8 19:49:00

对，答案是B

我感觉一般这么长的题目，代词可以是个入手点。

E, their的指代不清楚，恩，应该说已经歧义了，因为主句的主语，这里也是最近的名词，是car owner，car owner如何提高自己的fuel efficiency？

另外， up to five percent of a car’s fuel 后面是不是也应该用单数？

个人经验，对长的选项，对比选项中不一致的地方可以较快的入手。

看结构，B的结构最让人舒服。主谓宾的顺序一致。

lotery · 发表于 2004-3-9 11:27:00

no wonder (B) is best

but why (A) is flawed ?

以下是引用jediming在2004-3-8 5:39:00的发言：

199. 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.fficeffice" />

(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 underinflation.

cause -effect不清楚。应该是underinflation can waste up to ....

(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.

主谓一致，而频繁换主语也不好。

谢谢了！

多谢几位，很清楚了。总结几位发言如下-

解题思路：根据指代问题（pronoun), verb-subject agree问题，以及被动结构问题，迅速排除C,D,E

比较A和B, A"cause -effect不清楚。应该是underinflation can waste up to ...."

而B结构清晰，Because underflation can....., can owners can .... by inflating...

感觉句子的意思真的很重要，考试的时候如果碰到这样的题目，不知道是不是会在A和B中选对。

请指正。

XDF和以前的G友对此题的解题思路多是以因果的顺序为主，即应该是先因后果。但我觉得这个方法用来快速narrow the range是可以的，但不能作为唯一的依据。我们注意到OG对每一题的解释往往有多处考点。我想题目中一定还有其他的错误。

比如：the increase in car-road friction can waste up to five percent of car fuel by underinflation.

请问the increase in car-road friction 的中心词是increase还是friction？

如果是increase，那increase能不能waste fuel? 谢谢。
