初中英语形容词比较级和最高级讲解与练习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 (原级) (比较级) (最高级)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 (原级) (比较级) (最高级)3)以辅音字母-y 结尾改 -y 为i,加上 -er 和-est 构成.happy (原形) (比较级) (最高级)4) 以一个辅音字母结尾重读闭音节词双写这个辅音字母然后再加 -er和-est。

big (原级) (比较级) (最高级)5) 双音节和多音节需用more 和 most 加在形容词前面来构成。

beautiful (原级) (比较级) (最高级)difficult (原级) (比较级) (最高级)常用的不规则变化的形容词的比较级和最高级:good/well---better---best many/much---more---mostlittle---less---least bad/ill---worse---worstfar------farther, further------farthest, furthestold------older,elder-----oldest,eldest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: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，主句+than+从句。

注意：从句常省去意义上和主句相同的部分, 而只剩下对比的成分。

Lily’s room is bigger than mine.The weather in Beijing is colder than that in Hainan.否定用not+比较级+than 或less thanThis question is less difficult /not more difficult than that one.Our teacher is we are. 我们老师的个子比我们的高。

It is today than it was yesterday. 今天的天气比昨天暖和。

This picture is than that one. 这张照片比那张照片漂亮。

This meeting is than that one. 这次会议不如那次会议重要。

The sun is than the moon. 太阳比月亮大得多。

形容词最高级的用法:用于两个以上的人和物进行比较, 其结构形式为:主句+the+形容词最高级+名词+表示范围的短语或从句，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.She is student in her class. 她是班上最好的学生。

Tom is boy in his basketball team. 汤姆是他们篮球队中最高的。

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

二、形容词各等级的用法：1.原级（同级）比较：as…as…; not as(so)…as…（1）“A…+as+形容词原级+as+B”He is as tall as me. 他和我一样高。

English is as interesting as Chinese. 英文和中文一样有趣。

否定句中的结构：(1)“A…not+as/so+形容词原级+as+B”It is not as/so good as what you said. 那没有你说的那么好。

（2）表示两者之间比…… 更……可用状语 a little,a bit,a lot,a great deal , much,even,still,far,rather,any等程度副词修饰：He made much fewer mistakes than I did.He is even richer than I.（3）表示两者之间进行选择“哪一个更.....”时，用句型“which/who is +形容词的比较级，A or B? ”表示。

Who is taller, Li Ming or Wang Tao?(4) 如果两者之间表示“最……”时要在比较级前加the，而且还用of the two, 短语：John is the clever of the two boys.Of the two boys, John is the clever.(5) the more….. the more….表示“越……越……”:The more food you eat, the fatter you are.The more books you read, the wider your knowledge is.(6) more and more….表示“越来……越……”:More and more students realized the importance of a foreign language.Our country is getting stronger and stronger.It’s getting warmer and warmer in spring.2.最高级：(1)表示三或三者以上的人或物中进行选择“哪一个最....”时，用句型“which/who is +the +最高级，A ，Bor C? ”表示。

The milk was so hot that we can’t drink it.(2) too…to…与 not enough toHe 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。
