形容词用于修饰名词和代词,表示人和事物的性质和特征。副词既可修饰动词,又可修饰形容词,其它副词,甚至整个句子。
(一)形容词和副词级的变化:
大多数的形容词、副词都有三个等级:
原级:
比较级:比较...,更...一些
最高级:最...
1、一般构成规律:
一般单音节词,直接加-er,-est
high
higher
highest
以e结尾的词,加-r,-st
nice
nicer
nicest
以单个辅音字母(非r)结尾的单音节词,双写末尾的辅音字母,再加-er,-est
thin
thinner
thinnest
以辅音字母+y结尾的双音节词,变y为i,再加-er,-est
happy
happier
happiest
多数多音节词和源于分词的形容词,在原级前加more,most
difficult
more difficult
most difficult
2、常见的不规则变化:
原级比较级最高级
good/well better best
bad/badly/ill worse worst
many/much more most
little less least
far farther/further farthest/furthest
old older/elder oldest/eldest
3、常见的比较级和最高级的基本句型及其用法:
原级的用法:
①肯定句型:
as+形容词(副词)原级+as…意思是“与……一样”
The boy is as clever as his brother.这个男孩和他的哥哥一样聪明。
Lucy writes as carefully as Lily.露茜写得和莉莉一样认真。
②否定句型:
not so/as+形容词(副词)原级+as…意思是“不如……“
Monkeys are not as strong as elephants.猴子不如大象强壮。
