二 讲解
(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，比较级与最高级。
　　形容词比较等级形式变化有规则的与不规则的两种。
　　规则变化
　　1）单音节词末尾加-er（比较级），-est（最高级）
　　【例】 原级 比较级 最高级
　　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（最高级）
　　【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（最高级）
　　【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（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与-est。以-e结尾的词只加-r与-st。
　　【例】 clever cleverer cleverest
　　narrow narrower narrowest
　　able abler ablest
　　easy easier easiest
　　5）其它双音节与多音节词皆在前面加单词more与most。
　　【例】 careful more careful most careful
　　difficult more difficult most difficult
　　delicious more delicious most delicious
　　不规则变化
　　原级 比较级 最高级
　　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。

　　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.

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

　　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：

　　三、 重点与难点：

　　形容词比较级与最高级
　　绝大多数形容词有三种形式,原级,比较级与最高级, 以表示形容词说明的性质在程度上的不同。
　　　　形容词的原级: 形容词的原级形式就是词典中出现的形容词的原形。 例如: poor tall great glad bad
　　　　形容词的比较级与最高级: 形容词的比较级与最高级形式是在形容词的原级形式的基础上变化的。 分为规则变化与不规则变化。
　　　　规则变化如下:
　　　　1) 单音节形容词的比较级与最高级形式是在词尾加 -er 与 -est 构成。
　　　　great (原级)            (比较级)            (最高级)
　　　　2) 以 -e 结尾的单音节形容词的比较级与最高级是在词尾加 -r 与 -st 构成。
　　　　wide (原级)          (比较级)           (最高级)

　　　　clever(原级)           (比较级)            (最高级)
　　　　4) 以 -y 结尾,但 -y 前是辅音字母的形容词的比较级与最高级是把 -y 去掉,加上 -ier 与-est 构成.
　　　　happy (原形)         (比较级)            (最高级)
　　　　5) 以一个辅音字母结尾其前面的元音字母发短元音的形容词的比较级与最高级是双写该辅音字母然后再加 -er与-est。
　　　　big (原级)             (比较级)            (最高级)
　　　　6) 双音节与多音节形容词的比较级与最高级需用more 与 most 加在形容词前面来构成。
　　　　beautiful (原级)?　              (比较级)                 (比较级)
　　　　difficult (原级)                 (最高级)               (最高级)
　　　　常用的不规则变化的形容词的比较级与最高级:
　　　　原级------比较级------最高级
　　　　good------better------best
　　     many------more------most
　　　　much------more------most
　　　　bad------worse------worst
　　　　far------farther, further------farthest, furthest
　　　　形容词前如加 less 与 least 则表示"较不"与"最不"
　　　　important 重要 less important 较不重要 least important 最不重要
　　　　形容词比较级的用法:
　　　　形容词的比较级用于两个人或事物的比较,其结构形式如下:
　　　　主语+谓语(系动词)+ 形容词比较级+than+ 对比成分。 也就是, 含有形容词比较级的主句+than+从句。注意从句常常省去意义上与主句相同的部分, 而只剩下对比的成分。

　　　　主语+谓语(系动词)+the+形容词最高级+名词+表示范围的短语或从句。
　　　　She is             student      her class. 　她是班上最好的学生。
