形容词和副词的比较级和最高级

形容词和副词的比较级和最高级
(一)规则变化:
1.绝大多数的单音节和少数双音节词,加词尾-er ,-est
tall—taller—tallest
2.以不发音的e结尾的单音节词和少数以-le结尾的双音节词只加-r,-st
nice—nicer—nicest , able—abler—ablest
3.以一个辅音字母结尾的重读闭音节词或少数双音节词,双写结尾的辅音字母,再加-er,-est
big—bigger—biggest
4.以辅音字母加y结尾的双音节词,改y为i再加-er,-est
easy—easier—easiest
5.少数以-er,-ow结尾的双音节词末尾加-er,-est
clever—cleverer—cleverest, narrow—narrower—narrowest
6.其他双音节词和多音节词,在前面加more,most来构成比较级和最高级
easily—more easily—most easily
(二)不规则变化
常见的有:
good / well—better—best ; bad (ly)/ ill—worse—worst ; old—older/elder—oldest/eldest
many / much—more—most ; little—less—least ; far—farther/further—farthest/furthest

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.
This is as good an example as the other is .
I can carry as much paper as you can.
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,20%等
He is three years older than I (am).
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,关键是要用或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……”
The earlier you start, the sooner you will be back.
5.降级比较用“the + 原级形容词或副词(不论是单音节还是多音节的)+ than 从句”
Today is less cold than yesterday.
6.一些特殊比较词组:
no more than 不过,仅仅;同……一样不能 not more than至多,不超过
no less than 多达,有……之多(加数字)(强调数量之多,带有感情色彩);一样,不亚于,恰好
not less than不少于(加数字)(无强调多少之意)
7.the + 最高级 + 比较范围(in表示环境范围;of或among表示对象范围)
He is the tallest of / among the boys.
He is the tallest in his class.
最高级前不加the情况:
①作表语的形容词最高级前,如果不是和别人(或别物)相比,常不加the
We are busiest on Monday.
②形容词最高级前有物主代词时,不再加the
Wang Hai is my best friend.
③最高级形式有时并不表示最高级概念,它只表示非常或“在很大程度上”,这时前边一般不加the
It’s a most important question. = It’s a very important question.
