great greater greatest small smaller smallest clean cleaner cleanest

【例】 fine finer finest wide wider widest
3）闭音节单音节词如末尾只有一个辅音字母，须先双写这个辅音字母，再加-er（比较级），-est（最高级）
【例】 big bigger biggest hot hotter hottest red redder reddest
4）少数以-y，-er，ow风热咳嗽吃什么药，-ble结尾的双音节词，末尾加-er（比较级），-est（最高级）。以-y结尾的词，如-y前是辅音字母，则变y为-i，再加-er和-est。以-e结尾的词只加-r和-st。

delicious more delicious most delicious
不规则变化
原级 比较级 最高级
good------better------best many------more------most much------more------most
bad------wor------worst far------farther, further------farthest, furthest
形容词前如加 less 和 least 则表示"较不"和"最不"
important 重要 less important 较不重要 least important 最不重要
注：有些形容词一般没有比较等级。如： right, wrong, woolen等。
形容词的比较等级的用法：比较级用于二者的比较。
【例】 Li Ping is older than Wang Hai. 李平比王海年纪大。
There are more students in Class One than in Class Two.一班比二班学生多。
二、 形容词各等级的用法：
1、 原级（同级）比较：as…as…; not as(so)…as…
We’ll give you as much help as we can. She isn’t as(so)active in sports as before.
2. 比较级：表示两者之间比…… 更……可用状语much, a little, even等修饰： He made fewer mistakes than I did. He is even richer than I.
3、 高级：形容词最高级前必须加the, 副词最高级前常省略the，后面多用of……， in……短语表示范围：
It was the most/least interesting story I have ever listened. 吃药能喝茶吗He is the tallest of the three.
4、 如果在两者之间表示“最……”时要在比较级前加the，而且还用of the two, of the pair短语：
John is the clever of the two boys. Of the two boys, John is the clever.
三、 重点与难点：
1、 as…as…结构：你和汤姆是一样好的孩子。
You’re a boy as good as Tom.=You’re as good a boy as Tom.
2、 (1)too…to与 so…that sb.can’t…的句型转换：前者为简单句，主语只有一个，而后者为复合句，主语有两个，试比较：
The milk was too hot to drink. The milk was so hot that we can’t drink it.
跳绳的最佳时间
(2) too…to…与 not enough to句型的转换：
He is too young to get married.=He is not old enough to get married.
The book is too difficult for me to read.=The book is not easy enough for me to read.
3、 形容词原级表示比较级含义：

John is less stupid than Mike. John is cleverer than Mike.
4、 用比较级表示最高级：约翰是班里最高的男生。
John is taller than any other boy in the class.
John is the tallest boy in the class. John is taller than :any other boy.
any of the other boy./all the other boy./any of the others./any one el.
5、 the more….. the more….表示“越……越……”:
