No.115 GWD11-26:

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  

a主谓不一致

b wordy加主谓不一致

然后我选了e

谁来给我解释一下后三个选项

谢谢

答案应该是E

D选项没有谓语动词,首先排除

C和E的主要问题点我认为是on earth状语的位置

我总结的一点,修饰语要紧靠修饰对象

c中on earth置于句首,只能修饰整个句子,所以不清楚On earth的具体修饰对象是什么

E中one earth紧接indications,修饰indications,修饰关系清晰
