比较级最高级变化口诀
两者之间做比较，尾巴er少不了
一般词尾加er，有e词尾只加r
单一辅音单音节，双写词尾加er
辅音加y很重要，去y变i加er
双多音节字太长，前加more比它强
遇到双多最高级，most放前最成立
重点记忆:形容词比较级的不规则变化原级--比较级--最高级
good/well--better--best
many/much--more--most
bad/ill--worse--worst
little--less--least
far--farther/further--farthest/furthest old--older/elder--oldest/eldest

英语语法---比较级和最高级的用法 在英语中通常用下列方式表示的词： 在形容词或副词前加more(如more natural,more clearly )或加后缀-er(newer,sooner )。 典型的是指形容词或副词所表示的质、量或关系的增加。英语句子中，将比较两个主体的方法叫做“比较句型”。其中，像“A比B更……”的表达方式称为比较级；而“A最……”的表达方式则称为最高级。组成句子的方式是将形容词或副词变化成比较级或最高级的形态。 一、形容词、副词的比较级和最高级的构成规则 1．一般单音节词和少数以-er，-ow结尾的双音节词，比较级在后面加-er，最高级在后面加-est； （1）单音节词 如：small→smaller→smallest short→shorter→shortest tall→taller→tallest great→greater→greatest （2）双音节词 如：clever→cleverer→cleverest narrow→narrower→narrowest 2．以不发音e结尾的单音节词，比较在原级后加-r，最高级在原级后加-st； 如：large→larger→largest nice→nicer→nicest able→abler→ablest 3．在重读闭音节（即：辅音＋元音＋辅音）中，先双写末尾的辅音字母，比较级加-er，最高级加-est； 如：big→bigger→biggest hot→hotter→hottest fat→fatter→fattest 4．以“辅音字母＋y”结尾的双音节词，把y改为i，比较级加-er，最高级加-est； 如：easy→easier→easiest heavy→heavier→heaviest busy→busier→busiest happy→happier→happiest 5．其他双音节词和多音节词，比较级在前面加more，最高级在前面加most； 如：beautiful→more beautiful→most beautiful different→more different→most different easily→more easily→most easily 注意：（1）形容词最高级前通常必须用定冠词the，副词最高级前可不用。 例句：The Sahara is the biggest desert in the world. （2）形容词most前面没有the，不表示最高级的含义，只表示"非常"。 It is a most important problem.=It is a very important problem. 6．有少数形容词、副词的比较级和最高级是不规则的，必须熟记。 如：good→better→best well→better→best bad→worse→worst ill→worse→worst old→older/elder→oldest/eldest many/much→more→most little→less→least far →further/farther→ furthest/farthest 二、形容词、副词的比较级和最高级的用法 1．“A + be +形容词比较级+ than + B” 意思为“A比B更……”。 如：This tree is taller than that one. 这棵树比那棵树高。 注意： ①在含有连词than的比较级中，前后的比较对象必须是同一范畴，即同类事物之间的比较。 ②在比较级前面使用much，表示程度程度“强得多”。 如：A watermelon is much bigger than an apple. ③very, quite一般只能修饰原级，不能修饰比较级。 2．“比较级+ and + 比较级”或“more and more +原级”表示“越来越……” 如：It becomes warmer and warmer when spring comes.
外研版初二上英语语法知识讲解 重难点知识讲解：形容词的比较级和最高级 一、比较级的定义：大多数的形容词都有三个级别：原级、比较级、最高级。其中比较级表示“更……”，用于两者之间的比较，用来说明“前者比后者更……”，比较级前面一般用much, even, a little修饰，其中even, much 只能修饰比较级。 二、比较级的构成： （1）规则变化： ①单音节和部分双音节的形容词一般在词尾加-er Eg: calm---calmer tall---taller smart---smarter ②以字母e结尾的直接在词尾加-r Eg: nice---nicer fine---finer large---larger ③以“辅音+y 结尾的词，变y为i，再加-er” Eg: early---earlier happy---happier busy---busier ④以重读闭音节的单个辅音字母结尾的词，双写辅音字母，再加-er Eg: big---bigger thin---thinner hot---hotter ⑤多音节或部分双音节的形容词在原级前面加more Eg: popular---more popular important---more important （2）不规则变化： 少数形容词的比较级变化是不规则的：good---better bad/ill---worse many/much---more little---less far---farther/further old---older/elder 三、比较级的用法: (一)当两个人或事物（A和B）进行比较时，我们需要用到形容词（副词）的原级或者比较级 1． Eg I am as tall as you.我和你一样高。 He runs as fast as I. 他跑得和我一样快。 2．表达“A不如B”用not as…as的结构。 公式: Eg I am not as tall as you.我没有你高。 He doesn’t run as fast as I. 他没有我跑得快。 2．表达“A大于B”用“比较级+than”的结构。 公式: Eg I am taller than you.我比你高。
英语中的比较级
比较句型 As /so ... as ... 结构︰as／so＋形容词或副词原级＋as… 说明︰此句型意为“…和…一样…”。比较两件东西，并表示它们的程度一样。第一个as 为<副词>，第二个 as 则为<副词><连接词>，引导<副词子句>，修饰第一个 as。在as…as 中可插入单数<可数名词>，即：“as＋<形容词>＋a／an＋<名词>＋as”。若是复数<名词>，可用“as many／few＋复数 <名词>＋as”；若是<不可数名词>，则用“as much／little＋<不可数名词>＋as”。“as＋原级（形、副）＋as＋原级（形、副）”这形式表示有关同一人（物）的两种不同的性质、状态是一样程度的，译作“既有…且还有…”。 he is as handsome as his brother (is). 他和他哥哥一样英俊。 judy goes to the movies as often as Sara does. 朱迪像莎拉一样时常去看电影。 old john goes to sleep as easily as a baby does. 老约翰像婴儿一样容易入睡。 the girls are as busy with their work as bees. 这些女孩子就跟蜜蜂一样忙着工作。 he is as nice a boy as peter (is). 他和彼得一样都是好男孩。 she has as many friends as mary (does). 她和玛丽一样有许多朋友。 he has as much money as john (does). 他和约翰一样有很多钱。 he is as clever as (he is) handsome. 他不但英俊而且聪明。 my teacher is as kind as (she is) intelligent. 我的老师不但善良而且聪慧。 as many/much ...

初中英语语法之形容词比较级和最高级讲练 (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） 【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 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。
形容词比较级的用法讲解 形容词比较级的基本用法，即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和主句相同的部分, 而只剩下对比的成分。 It is warmer today than it was yesterday. 今天的天气比昨天暖和。 This picture is more beautiful than that one. 这张照片比那张照片漂亮。 1. 同级比较 两个比较对象程度相同时，用“as+形容词原级+as的结构” 例如：Tom is as tall as his brother. My hair is as long as mine. 在这两种结构中，第一个as是副词，而第二个as是连词；在第二个as的后面接名词、句子或代词的主格（一般不要接代词的宾格）。例如： His bedroom is not as big as his sister's. It is not so hot as yesterday. 2、在比较级+ than的结构前可以加上某些副词类的词，以对其进行修饰，如：far（远），even（甚至），much（许多），still（更，
还），a lot（许多），a little / bit（一点），rather（相当地），等等。例如： She’s a little more outgoing than me. My bike is much newer than his. 3、比较级中的两个特殊作用的结构是： a.The +比较级+ 句子，the + 比较级+ 句子。它表示的意义是"越（怎么样就）越（怎么样）"，在这个结构中的两个"比较级"不要求一定词性相同，它们各自的词性要依句子的需要而定。 例如： The harder you work at your study, the better grades you will have. 你学习越努力，你的成绩就越好。 The more we get together, the happier we’ll be. 朋友越多，我们就越高兴。 b. 比较级+ and + 比较级。它表示的意义是"越来越（怎么样）"，在这个结构中的两个"比较级"则要求词性相同。例如： Our country becomes more and more beautiful. When spring comes, the weather is warmer and warmer.
☆形容词的比较级☆ 当我们需要对事物作出比较时，需要用到比较级。 比较级的句子结构通常是： 什么 + 动词be (am , is , are ) + 形容词比较级 + than（比）+ 什么 ,如： I’m taller and heavier than you. （我比你更高和更重。） An elephant is bigger than a tiger.（一只大象比一只老虎更大。）形容词的比较级是在形容词的基础上变化而来的，它的变化规则是： ①一般的直接在词尾加er ，如 tall - taller , strong - stronger , ②以e结尾的，直接加r ，如 fine – finer , ③以辅音字母加y结尾的，先改y为i再加er，如funny - funnier ④双写最后的字母再加er，如big – bigger, thin – thinner , hot – hotter 除此之外，还有几个特殊的单词，它的比较级和最高级都是不规则的，如：many / much（原形）– more（比较级）– most（最高级） little / few（原形）– less （比较级）– least（最高级） good（原形）– better（比较级）– best（最高级） bad （原形）– worse（比较级）– worst（最高级） far （原形）– further– furthest 附加：形容词的最高级变化类似于比较级，只是把词尾的er改成est，如： tall （原形）- taller （比较级）- tallest （最高级） long（原形）- longer（比较级）- longest（最高级） big （原形）- bigger（比较级）- biggest（最高级） ☆注意☆比较的两者应该是互相对应的可比较的东西。
形 容 词 的 比 较 级 和 最 高 级 变 化 规 则 B.部分双音节与多音节的词比较级在原级之前加more, 最高级在原级之前 加most beautiful---more beautiful---most beautiful interesting--- difficult--- C.不规则变化的形容词: little / few（原形）- less （比较级）- least（最高级） good（原形）- better（比较级）- best（最高级） bad （原形）- worse（比较级）- worst（最高级） far （原形）-- further—furthest 例句： Tom is tall. John is tall. Bob is tall. I'm as tall as you. Tom is as tall as John.
Bob is taller than John. John is the tallest of the three. John is the tallest in his class. 写出以下各形容词的比较级和最高级： 1. nice ______________________ 2. fat ____________________ 3. slow _____________________ 4. dry ____________________ 5. happy ____________________ 6. wet ____________________ 7. much ____________________ 8. ill _____________________ 9. little _____________________ 10. bad ___________________ 11. thin ______________________ 12. far ____________________ 13. early _____________________ 14. careful_________________ 15. exciting ___________________ 16. busy __________________ 2. 根据句意，用所括号内所级形容词的比较等级形式填空： 1.

His brother is youn ger tha n me. Beiji ng is more beautiful tha n Osaka. （形容词或副词前有much, a lot, a little, far, still, even等词时，要用比较级） This story is much more in teresti ng tha n that one. 这个故事比那个有趣的多。 2、在比较级的句子中有“ of the two之类意义的词组时，比较级前要用定冠词the。 Bill is the taller of the two boys. 比尔是两个男孩中个子较高的一个。 3、比较级+and+比较级，表示越来越..... ”（多音节词要用“ more+and+more原级”。
