大全401 - 关于同位语结构的题

寂寞的自由

4 In terms of physics, the characteristic feature of the roller coaster is that the cars' potential energy, gained through their being lifted by a chain drive through the Earth's gravity to the top of the first drop, has been converted to kinetic energy by the time the ride ends.  
(A) cars' potential energy, gained through their being lifted by a chain drive
(B) cars' potential energy, a gain achieved as they are lifted by a chain drive
(C) potential energy from the cars' being lifted by a chain drive
(D) potential energy of the cars, gained as a chain drive lifts them
(E) potential energy gained by the cars, being achieved while a chain drive lifts them

正确答案是D，请问大家各个选项如何找出错误进行判断呢？谢谢

lingxia

A、B cars' potential energy这样的表达不如potential energy of the cars，同时使后面的their、they没有指代对象
C   from the cars' being lifted by a chain drive  错
E  being achieved 错  gained、 achieved意思重复

不知道这样理解对不对

寂寞的自由

C   from the cars' being lifted by a chain drive  错
E  being achieved 错  gained、 achieved意思重复

这两个自由还有些疑问，我的理解是：好象ETS在GMAT中要求“ BEING DONE”是一个绝对错误的形式作为一个名词的定语，是不是呢？请LINGXIA 以及各位朋友给予确认，谢谢
感谢2楼的朋友你的解释给自由又开拓了思路，谢谢~~~~~，呵呵，咱两个的头像挺象的，只是你手中有吃的东西，而我急的手舞足蹈，哈哈！

lingxia

应该是吧，好像没见到being done正确的选项

although i am not 100% positive, i still think you r right.
1, usage like "car's being lifted" is wrong! when i looked at the question, i eliminated A, C,E right away
2, there r 2 reasons why B is not good
    1) 'car's potential energy' is not proper.  as cars, some lifeless stuff, can not own anything. normally we say, 'my book' 'the battery of my cell phone'
    2) B is not precise. it seems to me that ETS prefers to have precise expression whenever possible

觉得有几个原则试用这道题: 过去分词修饰的时候直接放与被修饰词后面,不加being; 用主谓结构表达比介词短语through.../by...做状语或者同位语都要清楚; as表一段持续过程, 对应文中意思; 主动比被动好!

     每次rabbitbug MM的发言，都能带给我一点思考，MM对OG研究之透彻，亦令我佩服！

     MM准备什么时候考？？一定是个牛分

rabbitbug

见笑了! 只有不到两个星期了,可是我的逻辑不好, 痛苦中....

dreadpower

个人感觉逻辑主要是看懂题，抓住结论，去体会作者意图（这个非常重要）


    祝考个牛分！！！！
