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；

（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

Comparatives and Superlatives 比较级和最高级一、形容词比较级和最高级的规则 其它不规则的变化：
二、形容词比较级基本用法 1、定义：两个人或物之间的比较。表示“较……”或“更……一些”。标志词：than (比）eg: Cats are more lovely than other animals. 2、与than搭配的词语形式 （1）名词/代词He is older than me. (2) 动名词/从句Skiing is more exciting than skating. (3) 状语/动词/形容词 3、形容词/副词比较级前的修饰语 （1）much/a lot/ a bit/ a little/ slightly She is feeling a lot/much better today. (2) any/ no/ even/ some/ still Do you feel any better today? She is no older than mike. (3) 数词 My sister is ten years younger than me. 4、比较级的特殊搭配 1)“比较级+and+比较级”表示“越来越……” eg: He becomes fatter and fatter. 他越来越胖了。 2)“The +比较级…，the +比较级”表示“越……，越……” eg：The busier he is ,the happier he feels他越忙就越高兴。 The more ,the better. 3)表示两者中”较……“时，用the + 形容词比较级+ of 短语来表达。 eg: He is the taller of the two. 4)the more… the more… he harder you worker, the greater you will make. 5)more B than A = less A than B He is more lazy than slow at his work
形容词、副词的比较级和最高级用法 大多数形容词和副词有三个等级：原级、比较级和最高级。 1、原级即原型。 2、比较级，表示“较……”或 一些”。 3、最高级表“最……”。 一、构成。 变化两种。 （一）规则变化 ★★1.单音节以及少数双音节的词后面直接加-er,-est talltallertallest ★★2.以不发音的e 结尾只加-r ，-st nicenicernicest ★★3. 单音的辅音字 母，再加-er ，-est thinthinnerthinnest ★★4.“以辅音字母+y”结尾的词改y 为特别提醒： (1)以形容词+ly 构成的副词要在前面加 more ，most (2)new,few,slow,clean 等词含有字母组合,末尾 的辅音字母不用双写。 ★★5.大部分双音节词和多音节的词(即 音标中含有三个或三个以上元音音素的词)，要在前面加more ，most 特别提醒：由ing 分词和ed 分词演变过来的形容词(talent —talented)只能加more 或most 来表示它们的比较级和最高级。? 特别提醒：★比较级前最常见的修饰词是： much ，alittle,even 等。★very,quite,too 修饰原 级。 不规则变化?
★little-less-least用来修饰不可数名称，若修饰可数名称复数则用few-fewer-fewest; ★elder仅用于同辈之间的排行。“年长的”。 如:elderbrother(哥哥/兄长)；eldersister（姐姐）；elderboy（长子）；eldersister（长女）。在有than 的句子中，只能用older。 【归纳大荟萃】 形容词副词的比较级和最高级用法口诀 一者比较用原级，两者相比比较级，三者或以上最高级； 比较级，还是最高级？往往由他们来决定：有than就用比较级； i n或of最高级；若是没有这三词，那就看句意来定。 比较级和最高级变化口诀 原级变成比较级,er结尾要牢记；规则变化要牢记，特殊规则有三条：1．若是以e来结尾，只加r就可以；2.两辅（辅音字母）夹一元（元音字母）结尾的，双写末尾的辅音，最后再加er； 3.辅音字母若加y，要先把y变成i，最后再加er。（还有一条要注意：形容词+l y结尾的，根本不合这一条。）若不符合这三条，直接就加er。其余双音、多音节,词前加more就可以；不规则词没几个,它们需要特殊记。总共就有这五组：好坏多少加上远。 变最高级,也容易,原级后加est,规则类同比较级,提醒一点便可以；其余双音、多音节,词前加most就可以。还有一点要留意,最高级前要用the；若是副词最高级,用不用the皆可以。 二、句子构成： 1.当两者比较时，用句型： “甲+谓语+比较级+than+ 乙”译为“甲比乙…” 如:TomistallerthanKate.汤 姆比凯特高。 2.当三者或以上比较时，用 句型： “主语+谓语+the+形容词最高级+单数名词+in/of短语”译为“…是…中最…的”。 如:Tomisthetallest in hisclass. =Tomistallerthan anyother studentinh isclass. =Tomisthetallest of allthestudentsinhi sclass. 注：副词最高级前用不用the皆可以。如：Ijump(the)farthestinmyclass.我是我们班跳得最远的。 3.当两者比较，有下列两种句型： （1）表示甲乙两者在某一方面相同时，用肯定句型： “甲+谓语+as/so+（形/副）原级+as+乙”译为“甲和乙一样…” 如：TomisasoldasKate.汤姆和凯特年龄一样大。 （2）若表示甲在某一方面不如乙时，用否定句型： “甲+谓语的否定+as/so+（形/副）原级+as+乙”译为“甲不如乙…” 如：TomrunsasfastasMike.汤姆和迈克跑得一样快。 【考考你的领悟能力】 将下列句子译成英文。 1、Alice比她的姐姐高。 2、Cindy比Nelly友好多了。
形容词比较级和最高级的用法 形容词原级的用法 1.说明人或事物自身的特征、性质或状态时，用形容词原级。 Eg.The flowers in the garden are beautiful. 2.有表示绝对概念的副词very,so,too,enough,quite等修饰时，用形容词原级。 3.表示A与B在某方面程度相同或不同时用形容词原级。 肯定句中的结构：A +as+形容词原级+as+B 否定句中的结构：A+as/so+形容词原级+as+B 表示“A是B的……倍”时，用“A+倍数+as+形容词原级+as+B”结构（一倍once，两倍twice，三倍及以上：数字+times） half as +形容词原级+as表示“……是……的一半” 形容词比较级的用： 1．比较级：常用于“比较级+than”结构。如：Cats aremore lovely than other animals 2．形容词的比较级可用much，a little，a lot，even。a bit，still，far，rather，any等修饰，使原来的比较级在语意上更加明确。如：Chickens are much smaller than cows. 3．表示两者之间进行选择“哪一个更……”时，用句型“which/who is +形容词比较级，A or B？”表示。 4．表示“几倍于……”时，用“倍数+比较级+than”表示。如:I’m three years younger than you 比较结构中还须注意以下问题： 1．比较级与最高级的结构还可以转换，意思不变。如：The Changjiang River is longer than any other river in China=The Changjiang River is the longest river in China. 2．当某一事物与其他事物做比较时，被比较事物中不能包括本身。如：He is taller than any other student in his class. 3．如果比较对象相同，可用that/those代替第二个比较对象。如：The weather in Shanghai is better than that in Wuhan. 4．两个比较级用and 连在一起可表达全面增加或减少，意为“越来越……”。

比较级最高级的用法 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.春天来了，天气变得越来越暖和了。 It is getting cooler and cooler.天气越来越凉爽。 The wind became more and more heavily.风变得越来越大。 Our school is becoming more and more beautiful. 我们的学校变得越来越美丽。 3．在含有or的选择疑问句中，如果有两者供选择，前面的形容词要用比较级形式。 如：Who is taller,Tim or Tom? 谁更高，Tim还是Tom? 4. “the +比较级……, the+比较级”，表示“越……越……”。 The more money you make, the more you spend. 钱你赚得越多，花得越多。 The sooner，the better.越快越好。 5. 表示倍数的比较级用法： ①. A is …times the size /height/length/width of B. 如：The new building is three times the height of the old one. 这座新楼比那座旧楼高三倍。(新楼是旧楼的四倍高) ②. A is …times as big /high/long/wide/large as B. 如：Asia is four times as large as Europe. 亚洲是欧洲的四倍大。(亚洲比欧洲大三倍) ③. A is …times larger /higher/longer/wider than B. 如：Our school is twice bigger than yours. 我们学校比你们学校大两倍。 6.形容词、副词的最高级形式主要用来表示三者或三者以上人或事物的比较，表示“最……”的意思。 句子中有表示范围的词或短语。如：of the three, in our class等等。 如：He is the tallest in our class.他在我们班里是最高的。 7."否定词语+比较级"，"否定词语+ so… as"结构表示最高级含义。 Nothing is so easy as this. =Nothing is easier than this. =This is the easiest thing. 8. 比较级与最高级的转换： Mike is the most intelligent in his class.
