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[BryanZhou1] .

 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

这是一个倒装句.

原句应为: The rate at which trees grow, as seen in the rings visible in the cross scetions of their trunks, is believed to  be among the surest inidactions of sunspot cycles.

因为原句头重脚轻, 所以用了倒装.

所以C "as seen in the rings visible in the cross scetions of their trunks"的位置违背了就近修饰的原则,变成了修饰sunspot cycles, 引起歧义,句意不通.

请问这里as 引导什么从句，好奇怪啊，为什么是就近修饰呢？

那E中就近修饰  那个词啊？

"as seen in the rings visible in the cross sections of their trunks" 在E 中就近修饰"The rate at which trees grow" 的中心词, 也是全句的主语 rate 呀!

as 在这里引导的不是从句, 是一个过去分词短语

as可以引导过去分词短语啊？

只知道as +n,和as引导句子。

mellowlife

Sure.

和介词like 比较, as 作连词时, 可以连接从句,而like 不可以.

However, 每一个连词都可以引导从句或短语,包括分词或介词短语.

做语法题,建议简单看看整个句子的大意,只看画线部分或记所谓的规则有时会confused.

请问，如果是介词引导的分词短语，在语法上是等同介词短语，还是分词短语做伴随状语呢？不好意思，这点我比较困惑。。。

我觉得as有点像做关系代词

as (is )seen in the rings visible in the cross section.

Like any star of similar mass would do, once the Sun has exhausted the hydrogen in its core, it expands into a red giant, eventually ejecting its outer envelope of gases to become a white dwarf.

 

(A) Like any star of similar mass would do, once the Sun has exhausted the hydrogen in its core, it expands into a red giant, eventually ejecting

(B) Like any star of similar mass, once the hydrogen in the Sun's core is exhausted, then it expands into a red giant and eventually ejects

(C) As in the case of any star of similar mass, once the hydrogen in the Sun's core is exhausted, it will expand into a red giant, and eventually ejecting

(D) As any star of similar mass would, once the hydrogen in the Sun's core is exhausted it will expand into a red giant and will eventually eject

(E) As would be the case with any star of similar mass, once the Sun exhausts the hydrogen in its core, it will expand into a red giant and eventually eject

as would be the case with也是关系代词.....
