英语基础知识的积累对大家英语学习能力的提高非常重要，同学们一定要多加练习。精品小编为大家整理了英语语法：形容词和副词，欢迎大家阅读。

一、形容词和副词的比较级和最高级

①一般的比较级和最高级在形容词或副词后加-er或-est，如：small —— smaller —— smallest

②以不发音-e结尾的形容词或副词直接加 –r或 –st，如large —— largest —— largest

③重读闭音节词尾是一个辅音字母的，需双写该辅音字母，再加-er或-est.

④以辅音字母加 y 结尾的形容词和副词，把“y”变“i”，再加 –er或-est.busy——busier——busiesthappy——happier——happiest

但一些双音节及多音节形容词或副词前要加more和most，如：slowly —— more slowly —— most slowlydifficult——more difficult——most difficultbeautiful——more beautiful——most beautiful; 但还有一些不规则的变化：good / well——better——bestmany——more——mostbad / ill / badly ——worse——worstlittle——less——leastfar —— farther / further —— farther / furthest

二、形容词和副词的等比句型

①as…as… 和……一样 I’m as tall as you.

②not as(so)…as 不和…… 一样(在否定句中常用so 来代替as)

如，I can’t run so fast as you.

另外as…as possible 为固定结构，如，as soon as possible， as quickly as possible 等。

在以上两个句型中形容词或副词一定要用原级。

三、形容词和副词的其它句型还有：

①形容词/ 副词 比较级 + than 句型 ，在than 后面的人称代词 用主语和宾语均可。He is older than I / me. 但是如果人称代词后有动词时，则只能用主格形式。如， Tom found more red leaves than I did.

②“the + 比较级， the + 比较级” 结构表示两个变化一起发生。如， The more you learn， the more you’ll know.

③“more and more”结构(指两个形容词比较级用and 连接)表示持续不断的变化。 如： I’m getting thinner and thinner.

四、修饰形容词和副词的比较级的副词要用much， a lot， a little， a bit， far等，very不能和比较级连用。如： The blouse I bought yesterday is a little less expensive. 昨天我买的衬衣比较便宜。To play basketball is far more enjoyable to the boy. 打篮球对于男孩子来说要有趣得多。

五、形容词的一些搭配，

如：be glad / happy/ pleased to do 很高兴做某事be sorry to do 很抱歉，很遗憾做某事be sure to do 一定/相信会做某事be ready to do 准备好做某事，乐于做某事get ready to do 为……做好准备等等。
