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.

　　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 man was so angry that he wasn’t able to speak.

　　The milk was too hot to drink.

　　The milk was so hot that we can’t drink it.

　　(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：
