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...
（A）构成
1.规则情况
单音节词和少数双音节词: 一般情况加er, est，如 clever-cleverer-cleverest
以字母e结尾的词，加r, st，如nice-nicer-nicest
重读闭音节、末尾只有一个辅音字母时，双写加er, est，如big-bigger-biggest
以辅音字母加y结尾的词，变y为i加er, est，如 early-earlier-earliest
部分双音节和多音节词，在词前加more, most，如slowly-more slowly-most slowly
2.不规则变化，须熟记：
good/well-better-best many/much-more-most far-farther-farthest
bad/badly/ill-worse-worst little-less-least
(B)常见的使用情况
1.as … as … 和...一样（中间用原级）
2.not as(so) … as 和...不一样（中间用原级）
3… than …. ..比...（用比较级）
4.有范围修饰的用最高级 如:in, of, among或用从句修饰的
eg.⑴Winter is the coldest season of the year.
⑵This is the best film that I have ever seen .
5.比较级+and+比较级 意为“越来越…...”
eg: wetter and wetter more and more beautiful
6. The+比较级，the+比较级 越…...就越…...
eg:The more, the better. 越多越好
(C)注意点：
1.形容词最高级前一定要用the,副词最高级前可省略。
2.可用much, a little, even, still等修饰比较级。
3.在比较级中为了避免重复，在than后常用one,that,those等词来替代前面提到过的名词。
eg:The weather here is warmer than that of Shanghai.
(D)掌握三种同义句转换：
1.He is taller than any other student in his class.
=He is the tallest (student)in his class.
2.This film is less interesting than that one.
=This film isn＇t as interesting as that one.
=That film is more interesting than this one.
3.I prefer maths to English.
=I like maths better than English.

此外，关于形容词、副词的内容同学们还须掌握：
1.形容词修饰名词作定语，跟在连系动词之后作表语。
2.副词修饰动词、形容词或其它副词
enough属例外词：形/副+enough to do enough+名词，如：
she is old enough to go to school. 她够上学的年龄了。
3.区别几组易混淆的副词:
“也”：too用于肯定、疑问句
also 较为正式书面语
either 用于否定句
“已经”：already 常用于肯定句、疑问句
yet 常用于否定句、疑问句
“不再”：no (not any) longer 从时间上讲
no (not any) more 从动作上讲
“如此、这样”：such 修饰名词 eg: such a big box
so 修饰形容词、副词 eg: so big
“单独、独自”：alone 作表语 =by oneself
孤独的 lonely 可作表语、定语
eg:A group of girls are singing and dancing ______ over there. (happy)
