形容词比较级和最高级

　　绝大多数形容词有三种形式,原级,比较级和最高级, 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

　　　　形容词的比较级和最高级: 形容词的比较级和最高级形式是在形容词的原级形式的基础上变化的。 分为规则变化和不规则变化。

　　　　规则变化如下:

1) 单音节形容词的比较级和最高级形式是在词尾加 -er 和 -est 构成。great

2) 以 -e 结尾的单音节形容词的比较级和最高级是在词尾加 -r 和 -st 构成。wide

3)少数以-y, -er, -ow, -ble结尾的双音节形容词的比较级和最高级是在词尾加 -er 和 -est 构成clever(

4) 以 -y 结尾,但 -y 前是辅音字母的形容词的比较级和最高级是把 -y 去掉,加上 -ier 和-est 构成.　happy　　　　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和最高级是双写该辅音字母然后再加 -er和-est。big　　　　6) 双音节和多音节形容词的比较级和最高级需用more 和 most 加在形容词前面来构成。

beautiful　　　　difficult　　　　

常用的不规则变化的形容词的比较级和最　　　　good------better------best many------more------most

　　　　much------more------most bad------worse------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

形容词比较级的用法: (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.

　　　　（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，比较级和最高级。

　　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（最高级）great greater greatest

　　2）单音节如以e结尾，只加-r（比较级），-st（最高级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）

　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。

　careful more careful most careful 　difficult more difficult most difficult delicious more delicious most delicious

　　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。

形容词最高级的用法:

　　　　形容词最高级用于两个以上的人和物进行比较, 其结构形式为:

　　　　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。

　　　　Shanghai is one of                  cities      China. 上海是中国最大城市之一。

　　　　This is              apple I have ever met. 　这是我见到的最大的苹果。

　　　　Tom is              boy in his basketball team. 　汤姆是他们篮球队中个子最高的孩子。

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 too angry to be able to speak. 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：

　　约翰不象迈克那么苯。John is not so stupid as Mike. 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 else.

　　5、 the more….. the more….表示“越……越……”:

　　The more books you read, the wider your knowledge is. The more food you eat, the fatter you are.

　　6、 more and more….表示“越来……越……”:
