第一篇：初中英语比较级和最高级的用法
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.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.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.2
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.Mike is more intelligent than any other student in his class
7.修饰比较级和最高级的词
1）可修饰比较级的词
①.a bit, a little, rather, much, far, by far, many, a lot, lots, a great deal, any, still, even等。
②.还可以用表示倍数的词或度量名词作修饰语。
③.以上词(除by far)外，必须置于比较级形容词或副词的前面。
注意： 使用最高级要注意将主语包括在比较范围内。
(错)Tom is the tallest of his three brothers.(对)Tom is the tallest of the three brothers.2)下列词可修饰最高级：by far, far, much, mostly, almost。
This hat is nearly / almost the biggest.注意：
a.very可修饰最高级，但位置与much不同。
This is the very best.This is much the best.b.序数词通常只修饰最高级。
Africa is the second largest continent.8.要避免重复使用比较级。
(错)He is more cleverer than his brother.(对)He is more clever than his brother.(对)He is cleverer than his brother.9.要避免将主语含在比较对象中。
(错)China is larger that any country in Asia.(对)China is larger than any other country in Asia.10.要注意对应句型，遵循前后一致的原则。
The population of Shanghai is larger than that of Beijing.4
It is easier to make a plan than to carry it out.11.要注意冠词的使用，后有名词的时候，前面才有可能有名词。
比较：Which is larger, Canada or Australia?
Which is the larger country, Canada or Australia?
She is taller than her two sisters.She is the taller of the two sisters.三.典型例题
1）----Are you feeling ____?
----Yes，I'm fine now.A.any well B.any better C.quite good
D.quite better
答案：B.any 可修饰比较级，quite修饰原级，well的比较级为better.2）The experiment was____ easier than we had expected.A.more B.much more C.much
D.more much
答案：C.much可修饰比较级，因此B，C都说得通，但easier本身已是比较级，不需more，因此C为正确答案。
3）If there were no examinations, we should have ___ at school.A.the happiest time B.a more happier time
C.much happiest time D.a much happier time 答案：D。
比较级和最高级的用法
1.两者相比（甲=乙），用“as+原级+as”表示 Tom is as tall as Mike.2.两者相比（甲〈 乙），用“not as(so)+原级+as”或“less than”表示 I didn’t do my homework so(as)carefully as you.The picture is less attractive than that one.3.两者相比（甲〉乙），用“比较级+than”表示
Our city is more beautiful than any other city in our country.注意：1)为了避免重复，在从句中常用one, that, those等词来代替前面提过的名词。
The weather here is warmer than that of Shanghai.The radios made in our factory are better than those in your factory.2)比较等级应注意避免和包括自己的对象比。比较级+than+
any other + 单数名词 all the other + 复数名词 anyone else
any of the other + 复数名词
3）如果形容词作定语修饰一个单数可数名词，一般将不定冠词a/an放在形容词之后。
Our neighbour has _____ ours.A.as a big house as
B.as big a house as C.the same big house as D.house the same big as
4）比较级前一般不用冠词，但若表示“两者中较……时”。比较级前要加定冠词。若比较级后有名词，常在比较级前加不定冠词，表示泛指。E.g.他是两者中较高的一个 He is the taller of the two.她唱得真动听！我可从未听过比这更好的嗓音了。
How beautifully she sings!I have never heard a better voice.4.三者或三者以上相比，表示最高级时，用“the +最高级”的结构表示，这种句式一般常有表示比较范围的介词短语。Zhang Hua is the tallest of the three.He works(the)hardest in his class.That was the least exciting football game I’ve ever watched.6 This hotel is the most comfortable I’ve ever stayed.注意：当最高级的前面无限定词the或有不定冠词a/an时，仅表示“很……，非常……”
Monday is my busiest day.星期一是我很忙的一天。
Qingdao is a most(very)beautiful coastal city.青岛是一个非常美丽的海滨城市。比较级的一些其他用法 1 倍数表示方法

第二篇：初中英语比较级和最高级总结
初中英语比较级和最高级总结
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。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)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(原级)(比较级)(最高级)
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(原形)(比较级)(最高级)
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(原级)(比较级)(最高级)
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(原级)?(比较级)(比较级)difficult(原级)(最高级)(最高级)
常用的不规则变化的形容词的比较级和最高级:原级------比较级------最高级good------better------bestmany------more------mostmuch------more------mostbad------worse------worst
far------farther, further------farthest, furthest形容词前如加 less 和 least 则表示“较不”和"最不
形容词比较级的用法:
形容词的比较级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。
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

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.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。
