形容词和副词的比较级¶
1. 形容词或副词比较级的修饰语¶
(1) 用于形容词或副词原级比较结构前的词语有：exactly, just, nearly, almost, hardly, twice, three times 等。¶
exactly/just as big as
与……正好一样大

(2) 修饰形容词或副词最高级的词语有：by far, the second, the third 等。¶

2. 形容词的原级或比较级表示最高级的意义¶
用形容词的原级或比较级也可表示最高级的意义，其结构为：
(1) 否定词语＋so/as＋形容词原级＋as。如：¶
No boy is so brave as Tom in his class.
在班里没有哪个男孩比汤姆更勇敢。
(2) 否定词语＋形容词比较级＋than。如：¶
Nothing is more exciting than to travel.
没有什么比去旅游更令人兴奋。
(3) the ＋形容词比较级＋than＋any other ＋单数名词/all the other ＋复数名词。如：¶
The technique is more than the other three.
这种技术比任何其他方法都有效。
This plan is nicer than the other three.
这个计划比其他三个都好。
注：大多数形容词是可分等级的，其等级性是通过比较级和最高级表现出来的。但有些形容词没有等级，不具有等级性的形容词主要是一些从名词派生的形容词。如：atomic, tidal, earthen, monthly, weekly 等。
一些表示起源的词。如：
British, English, original 等；
一些表示绝对意义的形容词。如：
dead , living , blind, lame, square, wrong 等；
一些表示时间、方位和方向的形容词。如：
daily,present, front , east, middle, central 等；
一些本身表示极限性质的形容词。如：
absolute, perfect, excellent,maximal , wonderful, unique 等。
