我选了C，答案是E，为啥呀？ 作者: huangyouhuifei 时间: 2011-5-11 22:49
<1> on earth是修饰indications的，应放在indication后，C选项将其放在句首修饰整句，导致句意ridiculous，在地球上是这样，莫非在月球、在火星上情况不是这样？ <2> 非划线部分应该就近修饰the rate at which trees grow的，C选项却修饰the surest indications of sunspot cycles，导致句意不符合逻辑。 <3> 例如： Among the tallest students in the class are Tom, Jerry, and Mike. Tom, Jerry, and Mike are among the tallest students in the class. 个人感觉GMAT更喜欢前者。作者: xibao 时间: 2011-5-12 18:11

1、逗号之后的内容修饰the rate at which trees grow， 2、主语是the rate at which trees grow作者: vivian2011 时间: 2011-7-27 22:38
