众所周知，状语从句是指句子用作状语时，起副词作用的句子。比较状语从句是其中重要的一种，主要运用于形容词和副词的原级、比较级及最高级的句子之中，通常由as或than引起。那么，比较状语从句还有哪些奥秘呢?下面作者就带各位2016考研人来一起学习一下。

比较状语从句常用引导词为as(同级比较)，than(不同程度的比较)，特殊引导词为the more...the more...; just as...,so...; A to B is what /as C is to D ; no ...more than ; not so much A as B 。

【例句】

Wealth is just like salt water, the more you drink, the more thirsty you will.

财富就像海水，你喝的越多，你就越喝。

Life is never as bad or as good as people say.

生活永远没有人们说得那么好或那么坏。

【知识拓展】写作当中经常会用到"……很重要"这一句式，用英语如何表达?something be important/essential的词汇表达。大家可以通过学习比较状语从句，来提升这种表达的层次，从而博取高分。

上述句子可以概括为A is to B what C is to D. 替换ABCD四个名词就可以用来表达"重要性"这一概念。例如：

人生态度--乐观与悲观

积极的态度对于生活，好比太阳对于地球一样。

A positive attitude is to life what the sun is to the earth.

赡养父母--家庭

家庭对于人类，好比生活对于人一样。

Family is to the people what life is to the individual.

谈读书

比较状语的倍数表达法：

①A+be +倍数+as many/much as +B

②A+be +倍数+the amount +B

③A+be+倍数+what it was +B

【例句】

中国1996年的离婚率近1956年的17倍。

①Divorce rate in China in 1996 is almost 17 times as much as that in 1956.

②Divorce rate in China in 1996 is almost 17 times the amount in 1956.

③Divorce rate in China in 1996 is almost 17 times what it was in 1956.

④Compared with the divorce rate in 1956 ,it has almost increased 17 times in 1996.

⑤By comparison with 1956 , divorce rate in China in 1996 has jumped from less than 0.5%,to almost 8.5%.
