直接加-er；-est
fast-faster-fastest

变y为i再加-er；-est
结尾的词
easy-easier-easiest； heavy-heavier-heaviest thin-thinner-thinnest
以一个辅音字母结尾的重读闭音节词
辅音字母双写再加-er；
big-bigger-biggest
-est
hot-hotter-hottest important-more important-most important
多音节词和部分双音节词
在单词前面加more和most
interesting-more interesting-most interesting
convenient-more convenient-most convenient
（2）不规则的形容词和副词的比较级和最高级如下表：
原级 good/well
比较级 better
最高级 best
lazy-lazier-laziest nice-nicer-nicest
bad/ill many/much little far
worse more less
farther/further
worst most least
farthest/furthest
（2）形容词和副词的比较级的用法如下：
①在表示程度相同时，用“as＋形容词或副词的原级＋as＋比较状语从句”句型。例如： Jim is as tall as his brother．
Bruce didn't come to the classroom as early as Dick yesterday． ②在表示一方不如另一方时，“not as ／so＋形容词或副词的原级＋as＋比较状语从句”句型。例如：
Lesson Three is not so easy as Lesson Two．It's much more difficult．第三课不如第二课简单，它难一些。
③在表示一方超过另一方时，要用“形容词或副词比较级＋ than ＋比较状语从句”句型。例如：
Peter is fatter than his brother．
④在表示三个或三个以上的人或事物中程度最高时，用句型“the ＋形容词或副词的最高级（＋名词）＋in ／of ／among（名词的复数形式或代词的宾格）”，副词的最高级前面的the可以省略。例如：
Which do you like best，tea，orange juice or water？
Of all stars，the sun is the nearest to the earth．所有星体中，太阳离地球是最近的。 —Which is the hottest season of the year？ —Summer．
—一年中哪一个季节最热？ —夏季。
⑤有些形容词由于受本身涵义的限制，没有比较级和最高级。如：dead，empty，round（圆的），sure，woolen等。例如：
This bottle is empty．There's no water in it．
⑥形容词比较级前面常用much，far，even，a lot，a little等词修饰。例如： I am a little stronger than you．我比你强壮一点儿。
This street is much straighter than that one．这条路比那条直的多。
In this country，it's very cold in November，but it's even colder in December． （3）级别之间的转换
①原级与比较级之间的转换
A．倍数＋as．．．as→倍数＋比较级＋than。例如： This book is twice as thick as that one．→ This book is once thicker than that one．
B．not so．．．as与比较级之间的转换。例如：
Tom knows much more about computers than any other student in his class．→No one in his class knows so much about computers as Tom．
Miss Zhang isn't so old as Miss Wang．→Miss Wang is older than Miss Zhang．／Miss Zhang is younger than Miss Wang．
②比较级与最高级之间的转换：
A．比较级＋than any other ＋名词单数。例如：
Wei Hua is the tallest boy in his class．→Wei Hua is taller than any other boy in his class． B．比较级＋than ＋any of the other ＋名词复数。例如：
Robert is better than any of the other students in the school．→ Robert is the best student in the school．
C．比较级＋than ＋anyone else。例如：
He spoke English more quickly than anyone else．→He spoke English most quickly． D．No one ＋谓语＋比较级＋sb．例如：
No one does the work better than Sam in his office．→Sam can do the work best in his office．
（4）级别的惯用法
①“比较级＋and＋比较级”，表示“越来……越……”，其形式为 -er and -er或more and more ＋部分双音节词和多音节词。例如：
The car is running faster and faster．It seems to be flying． Our school is becoming more and more beautiful．
②“the ＋比较级，the＋比较级”，表示“越……越……”。例如： —How many books do you need？—The more，the better． —Actually，the busier he is，the happier he feels．
