　　old—older/elder—oldest/eldest

　　many/much—more—most

　　little—less—least

　　far—farther/further—farthest/furthest

　　副词(及形容词)的特殊用法：

　　1.原级比较：as+adj./adv.+as(否定为not so/as+adj./adv.+as)

　　当as…as中间有名字时，采用as+adj.+a+n.或as+many/much+n.

　　Tom runs as fast as Jack.

　　表示倍数的词或其他程度副词做修饰语时放在as的前面。

　　This room is twice as big as that one.

　　倍数+as+adj.+as=倍数+the+n.+of

　　Your room is twice as larger as mine.=Your room is twice the size of mine.

　　2.比较级+than

　　比较级前可加程度状语much，still，even，far，a lot，a little，three years，five times等

　　表示“(两个中)较……的那个”时，比较级前常加the(后面有名字时前面才能加冠词)

　　He is the taller of the two brothers./He is taller than his two brothers.

　　Which is larger, Canada or Australia?/Which is the larger country, Canada or Australia?

　　可用比较级形式表示最高级概念，关键是要用any other或anybody else或否定词等把一事物(或人)与其他同类事物(或人)相分离。

　　He is taller than any other boy/anybody else.

　　Nobody is taller than him.

　　比较对象相同时，可用that，those等代词代替第二个比较对象。

　　The weather in Shanghai is better than that in Wuhan.

　　比较级+than与not so/as+adj./adv.+as的相互转换。

　　Maria is not so/as brave as Helen.=Helen is braver than Maria.

　　Nothing is so easy as this.=Nothing is easier than this.=This is the easiest thing.

　　3.“比较级+and+比较级”表示“越来越……”(加more构成比较形式的，只重复more，不重复原形容词或副词)

　　colder and colder，more and more beautiful

　　4.“the+比较级(……)，the+比较级(……)”表示“越……，越……”
