形容词和副词的比较级

大多数形容词和副词有三个等级：

原级、比较级、最高级。

一、形容词比较级的构成

1.构成的不规则变化:

1. 构成的不规则变化:

e.g. good / well – better – best

bad / badly – worse – worst

many / much – more – most

little – less – least

far – farther / further – farthest/ furthest

2.构成的规则变化:

1) 单音节词和少数双音节词一般在词尾后加-er 构成比较级或-est构成最高级. 如：

原级比较级最高级

cold –—— colder –—— coldest

bright——— brighter———brightest

young—— younger—— youngest

2) 以字母 e 结尾的词只加 –r 或-st 构成比较级和最高级。

原级比较级最高级

nice ——— nicer –——— nicest

fine——— finer———— finest

large —— larger ———— largest

... ... ...

形容词的最高级

1. 用法：英语中三者或三者以上相比较，表示

“最……” 这样的最高程度概念时，要用 “the+最高级” 的结构表示。这种句式一般带有表示比较的介词短语，比如: in our class, of the three 等。

例如：Wang Lin is the tallest in our class.

This theater is the cheapest of the three.

注意使用最高级时应注意以下几点：

(1) 表示 “最……之一” 的句式，要用 one of the+形容词最高级+复数名词。

例如: Jingjiang Hotel is one of the biggest hotels in our city.

Lisa is not one of my best friends.

(2) 当最高级前面有物主代词或名词所有格时，不加定冠词 the。

例如：Tom is Lucy’s best friend.

Tuesday is her busiest day.

... ... ...

最高级规则变化口诀：

最高级，很容易，一般词尾加est。

(cheap-the cheapest)

词尾若有哑音e, 直接就加st。

(close-the closest)

重读闭音节, 单辅音字母要双写。

(big-the biggest)

辅音字母加y, 记得把y变为i。

(friendly-the friendliest)

多音节，考考你，the most到底加哪里？

(popular-the most popular)

不规则变化

good / well – better - best

much / many – more - most

bad / badly / ill – worse – worst

little – less – least

far – farther/ further– farthest – furthest

old – older/ elder – oldest / eldest
