以下是引用寂寞的自由在2003-12-25 5:53:00的发言: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
补充一点:
本题中的gained乍看上去,好像有可能修饰cars,但语义上修energy,于是有人说这有歧义!我认为没有。原因如下:
them所指代的是cars,所以其前面的逻辑主语项应该不是其本身,而是另外的部分。记得以前我也留意这类问题。
所以定语从句/相当于定语成份的修饰部分的跳跃修饰,要结合前后的代词指代来进行判断。 |
