这题选E？ 可以排除A,B,D，但是C有点犹豫。就是在于On Earth的位置。

这道题的句子成分不是很清楚？？

答案是E
Among the surest indications on Earth of sunspot cycles is believed to be the rate at which trees grow, as seen in the rings visible in the cross sections of their trunks

该句是倒装句, the rate at which trees grow, as seen in the rings visible in the cross sections of their trunks, is believed to be among the surest indications on Earth of sunspot cycles.

on earth是修饰indications的，即树木生长的快慢是地球上最能表明黑子周期性存在的依据之一，如果把on earth放句首，就成了：在地球上树木生长快慢被认为是依据之一，在其他星球上可能就不被这么认为了。

应该是C
E就算倒装也不能把宾语补足语的留一半倒一半吧

E
Prep语法笔记#1-139

句子结构：Among… is believed to be…
倒装结构，主语是the rate，由which引导定语从句修饰。

考点：句子结构、逻辑表达、主谓一致
句子结构-倒装，介词短语作表语提到句首，整个句子使用倒装结构。
逻辑表达，状语的位置要合理，结合句意看是否符合逻辑。
主谓一致，倒装结构的句子主语不太明显，要找对主语，并注意其单复数。

(A) among倒装，主语应该是the rate，所以应该用单数is。
(B) among倒装，主语应该是the rate，所以应该用单数is；tree应该用复数，使未划线部分的their有
一致的指代对象。
(C) on earth    放置句首修饰整个句子，不符合逻辑；their    的指代存在歧义，离它最近的是    sunspot
cycles，未划线部分的 as seen 应该要紧跟其修饰的名词。
(D) tree应该用复数，使未划线部分的their有一致的指代对象；谓语结构不完整，应该用is believed
被动语态。
(E)    正确，on Earth修饰indications，主语是the rate，谓语动词用单数is。
