形容词和副词有三个等级,即原级、比较级和最高级。构成规则有两中情况,即规则变化和不规则变化。不规则变化需记忆,规则变化如下:

单音节形容词和副词通常都采用原级加词尾-er 构成比较级形式,原级加词尾-est则构成最高级形式/ 多数双音节、三音节及三音节以上的形容词采用“more+原形”构成比较级形式;“most+原形”构成最高级形式。少数单音节和部分双音节形容词也more,most形式。

★该句型还可表示“是……的多少倍”:表示倍数的词+as+many(much)+as从句。

She can write twice as fast as I。

★当形容词前有不定冠词时,则不定冠词必须放在形容词后,句型为:as+adj+a/an可数名词(单)+as 例如Dick is as handsome a boy as Bill。

英语语法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. 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.

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 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。

(完整版)英语比较级的用法

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。

形容词比较级的用法讲解

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.
