初中英语的语法一个重要的知识点就是形容词的比较级和较高级的辨析。比较级和较高级的一个判断的标志就是识别主格和宾格。主格和宾格的搭配是判断比较的等第的，这些重点的知识在下文中都会给大家讲述。说到形容词的比较级和较高级的用法，在英语的句式中有一些规则的和不规则的，大家需要掌握的一个重点就是不规则的一些变化，这些一般没有什么规律可循，大家需要重点的进行记忆。

　　形容词比较级

　　(一)一般句式的构成： A + is / are+ 形容词比较级+ than + B

　　A 是主格 B 是宾格

　　如： She is taller than me.

　　主格 形容词比较级 宾格

　　(二)英语形容词比较级的构成

　　英语形容词比较等级有三个：原级，比较级和较高级。

　　形容词比较等级形式变化有规则的和不规则的两种。

　　规则变化

　　1)单音节词末尾加-er(比较级)，-est(较高级)

　　【例】 原级 比较级 较高级

　　great greater greatest

　　small smaller smallest

　　clean cleaner cleanest

　　2)单音节如以e结尾，只加-r(比较级)，-st(较高级)

　　【例】 fine finer finest

　　wide

　　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(较高级)

　　【例】 big bigger biggest

　　hot hotter hottest

　　red redder reddest

　　4)少数以-y，-er，ow，-ble结尾的双音节词，末尾加-er(比较级)，-est(较高级)。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。

　　【例】 clever cleverer cleverest

　　narrow narrower narrowest

　　able abler ablest

　　easy easier easiest

　　5)其它双音节和多音节词皆在前面加单词more和most。

　　【例】 careful more careful most careful

　　delicious more delicious most delicious

　　不规则变化

　　原级 比较级 较高级

　　good/well better best

　　bad worse worst

　　many/much more most

　　little less least

　　far farther/further farthest/furthest

　　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。

　　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：形容词较高级前需要加the, 副词较高级前常省略the，后面多用of……， in……短语表示范围：

　　It was the most/least interesting story I have ever listened.

　　4、如果在两者之间表示“较……”时要在比较级前加the，而且还用of the two, of the pair短语：

　　Of the two boys, John is the clever.

　　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.

　　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 not easy enough for me to read.

　　3、 形容词原级表示比较级含义：
