as做定语从句引导词(关系代词)指代the rate at which trees grow. 所以离其所指代的部分越近越好。而C里面as有修饰the surest indications of sunspot cycles的歧义。
on earth在E里面修饰indications,意味着"地球上的迹象",在C里面修饰全句,意味着"地球上的人这么认为",细究意思,还是E比较恰当。

弱问as怎么可以引导定从了?
我所知道的:
As+句子/介词:1、当……时;2、因为;3、比较
As+n./pronoun:1、作为;2、in the period of;3、equivalent(regard...as)

关系代词as,but和than也“兼职”
定语从句是大家非常熟悉的一种从句,在考试中可以说是无处不在。说到定语从句的关系代词,大家肯定会异口同声地喊出“that”“which”“who”……今天我们要讲讲as、but和than这三个特殊的关系代词。
As、but和than通常都是以介词、连词等身份被大家所熟知,而它们居然可以摇身一变成为关系代词,在定语从句中做主语和宾语。
As最基本的用法是做连词“与……一样”表示同级的比较,介词“作为”。下面是它特殊的用法,例句:
1. He does not possess such qualifications as are necessary to be an actor.他并不具备一名演员应有的资格。
2. She bought the same skirt as I had bought last week so I need to talk to her about it so we don't wear them the same at the same time.她买的那条裙子和我上周买的一模一样,我要和她商量一下,免得“撞衫”。
上面两个例句中定语从句都使用了as作为关系代词,我们可以发现例句1中含有“such…as…”,例句2中含有“the same…as…”,由此可见,我们到底要不要使用as来做关系代词,可以根据句中是否出现了与as搭配的短语进行判断。
3. The murderer who had killed several people on the campus was finally arrested by the police, as was expected.如我们所愿,那个在校园杀害数人的杀人犯终于被警方逮捕。
该句中并未出现与as搭配的短语,此处的用法是as做关系代词指代前面整个句子,在定语从句中做主语。
再来看一个:
as,than可以做比较从句的主语。à所以在这里
In one of the bloodiest battles of the Civil War, fought at Sharpsburg, Maryland, on September 17, 1862, four times as many Americans were killed as would later be killed on the beaches of Normandy during D-Day.
As指代了americans。曾的出过结论,定语从句引导词可以跳过非常简单的谓语结构去修饰先行词,这里就是as跳过了were killed来修饰Americans。(上面的第一个例子是没有跳的。)
But
大家熟悉的but基本都是以转折连词的身份出现,但是它还兼职在做定语从句中的关系代词。
例句:There is no man but errs.没有任何人能够不犯错误。
句中的先行词是man,but自然就充当了关系代词的角色,但我们从句意中可以发现,but带有一层否定的意思,相当于“who not”。那么我们可以把例句转换为:
There is no man who does not err.
但要注意,只有在but 前有先行词的时候才有此用法!请比较下面这个例句:
He did nothing after graduation but spend his parents' money.他毕业之后无所事事,就知道花爸妈的钱。
该句中but是介词的用法,有转折的意义。
Than
即可以做连词也可以做介词的than都是比较的含义,它居然也可以用在定语从句中。
例句:1. Parents had better not give kids more money than is needed.父母最好别给孩子们太多的钱,够用就可以了。
2. Don't order more food than can be finished.别点太多吃的,会吃不完的。
此处Than以主语的形式出现在定语从句中,其实省略了what,than也就等于than what。例句也可以写作:Parents had better not give kids more money than what is needed
例句2则可以转换为:Don't order more food than what can be finished
不管是做介词、连词也好,在定语从句里做关系代词也罢,than都表示了一个比较的关系,从上述两个例句来看,句中都出现了比较级的形式。
