比较级和最高级的讲解
变化规则
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

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

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.
③ very, 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.

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。
He likes English best of all the subjects
在所有学科中，他最喜欢英语。
7."否定词语+比较级"，"否定词语+ so… as"结构表示最高级含义。

1）可修饰比较级的词

b. 序数词通常只修饰最高级。
Africa is the second largest continent.
10.要避免重复使用比较级。
(错) He is more cleverer than his brother.

☆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。
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 女口：small f 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
比较级、最高级练习题 一．用所给形容词和副词的适当级填空： 1.Tom is (lazy) student in our class. 2.There are (few) books in this library than in that one. 3.I have (little) free time than he. 4.Mary is (young) than her husband. 5.My watch runs (fast ) than his. 6.The days are (long) in summer than in winter. 7.This box is (large) one in the room. 8.He knows (many) people than you. 9.This box is (heavy) than that one. 10.This film is (interesting) I have ever seen. 11.It rains (often) in Shanghai than in Beijing. 12.He made (many) mistakes than I. 13.Her family is (rich) in the room. 14.Fudan University is (famous) than our college. 15.This road is (wide) than that street. 16.The room is (bright) than mine. 17.Your book is (thick) than Tom’s. 18.The water in this river looks (dirty) than in that one.
英语比较级的用法 一忌使用双重比较级 即构成比较级时不能既加词尾-er，又在其前加more。如： 他的英语比我的英语好多了。 误：His English is more better than mine. 正：His English is much better than mine. 【注】虽不能说more better, most earliest 之类的，但可用“比较级+and+比较级”这样的形式： It’s getting warmer and warmer. 天气变得越来越暖和。 I’m getting fatter and fatter. 我越来越胖了。 We’re going more and more slowly. 我们越走越慢了。 要想加强比较级的语气，可用much, far, even, still, rather等修饰。如： This is very much cheaper. 这个便宜得多。 This one is even more expensive. 这个更贵些。 The patient is much better now. 病人现在好多了。 二忌比较对象不一致 如果有人问你“一公斤苹果多还是一尺布多”时，你会怎么回答？你肯定认为无法回答。对，无法回答，因为它们“单位”不一样，或者说它们不是同一类型的两个比较对象。在使用英语的比较级时，也要特别注意不要“比”错了对象。如： Her French was no better than mine. 她的法语比我好不了多少。 My dictionary is more useful than yours. 我的词典对你的词典更有用。 All your neighbours are noisier than ours. 你们的所有邻居都比我们的吵闹。
形容词比较级 (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 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, 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。 二、形容词各等级的用法： 1、原级（同级）比较： （1）very、so、quite、too等词后用原级
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。 ②②在比较级前面使用much，表示程度“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。T he sooner，the better. 越快越好。 5. 表示倍数的比较级用法： ①. A + be +倍数+ times + the + 形容词对应名词形式+ 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 + be +倍数+ times +as +原级+ 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 + be + 序数词+比较级+ 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

英语比较级的用法总 结
☆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 收集于网络，如有侵权请联系管理员删除
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。 典型错误：My hair is longer than you.（我的头发比你更长。） 比较的两者是我的头发、你（整个人），那么比较的对象就没有可比性。 应该改为：My hair is longer than yours. 或My hair is longer than your hair. 附：如果比较的两者是一样的时候，我们会用 as…as…这个词组，它的用法是： 什么+be+as+形容词原形+as+什么，意思是什么和什么一样……。如：I’m as tall as you.（我和你一样高。） My feet are as big as yours.（我的脚和你的一样大。） 比较级专项练习 一、从方框中选出合适的单词完成句子 (1) How is the Yellow River? 收集于网络，如有侵权请联系管理员删除
