请教一道争议题

On Earth, among the surest indications of sunspot cycles are believed to be the rate that trees grow, as seen in the rings visible in the cross sections of their trunks.

A.       On Earth, among the surest indications of sunspot cycles are believed to be the rate that trees grow

B.       On Earth, among the surest indications of sunspot cycles are, it is believed, the rate of tree growth

C.       On Earth, the rate at which trees grow is believed to be among the surest indications of sunspot cycles

D.       Among the surest indications on Earth of sunspot cycles, believed to be the tree growth rate

E.       Among the surest indications on Earth of sunspot cycles is believed to be the rate at which trees grow  

该题到底该选C还是E呢？？？

求详解，谢谢！

选C，划线部分后面跟的是一个从句，所以谓语动词应该在划线句子中

其他选项都没有谓语动词

ls胡说，什么其他没谓语动词，这里都是倒装。。。

介宾短语前置啦~

至少a，b，c，e都有动词，至于该选哪个，我也不晓得，我再研究下~

jason_alex

看出来了，是c，没错，是c~

on earth放句中会有歧义，of sunspot cycles应该是修饰indications的，如果把on earth插入句中，则of sunspot cycles则修饰了 earth，逻辑不对了。

大家还有什么看法吗。好多地方也说是E阿???

edmundshi

能说清楚点吗？还是看不出来

怎么倒装的？

能把句子还原下吗？

这是道难题.

C的问题有两个:

1. On Earth放句首, 作为整个句子的状语使得句子的逻辑有误;

2. 未划线部分their trunks的their应该指代trees (trees才有trunks嘛~), 但C答案里面trees和their中间还夹了一个indications, 使得句子表达不清晰了;

因为介词短语among...放在句首,所以句子需要完全倒装, 即: Among...is believed to be..., rate是主语.

这题在旧版prep上有, 建议刚刚接触GMAT的同学把PREP语法笔记或者OG12(很多gwd题)作为教材. GWD答案不确定的太多.

我觉得是E
