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。 规则变化如下: 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) greater(比较级) greatest(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) wider (比较级) widest (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) cleverer(比较级) cleverest(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) happier (比较级) happiest (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) bigger (比较级) biggest (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)? difficult (原级) more beautiful (比较级) more difficult (比较级) most beautiful (最高级) most difficult (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 best many more most much more most bad worse worst little less least ill worse worst far farther(further) farthest(furthest) 形容词前如加 less 和 lest 则表示"较不"和"最不" important 重要 less important 较不重要 lest important 最不重要 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。 Our teacher is taller than we are. 我们老师的个子比我们的高。 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。 This meeting is less important than that one. 这次会议不如那次会议重要。 The sun is much bigger than the moon. 太阳比月亮大得多。 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。 She is the best student in her class. 她是班上最好的学生。 Shanghai is one of the biggest cities in China. 上海是中国最大城市之一。 This is the biggest apple I have ever met. 这是我见到的最大的苹果。 Tom is the tallest boy in his basketball team. 汤姆是他们篮球队中个子最高的孩子。 有关形容词的几个特殊用法: most 同形容词连用而不用 the,表示 "极,很,非常, 十分"。 It's most dangerous to be here. 在这儿太危险。 I cannot do it, it's most difficult. 我干不了这件事，太难了。 "The+形容词比较级..., the+形容词比较级..."表示 " 越... 就越..."。 The more you study, the more you know. 你学的越多, 就知道的越多。 The more I have, the more I want. 我越有就越想要有。 The more, the better. 越多越好。 " 形容词比较级 + and + 形容词比较级 ", 表示 " 越来越...

比较级（Comparative Form）就是将二者进行比较产生的词形，是由形容词原级转化而来，是在原级后面加er,也有一些不规则的转化，比如good—better，bad—worse，有很多。
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。组成句子的方式是将形容词或副词变化成比较级的形态。
比较级的用法
1、表示"比...更"。用比较级形容词+than+比较成分，than后主词的述语动词往往省略，非正式用法的than后的人称代名词可用宾格。
2、表示"较...低; 不及..."用less+原级形容词+than+比较成分。
3、表示两者之中"较..."，用the+比较级+of the two。
4、定冠词或指示形容词+比较级+名词表示比较。
5、比较形容词可以被副词如a little（一点），much（得多），even（更加）， still（更加），far（...的多）等修饰，但不可用very修饰。
6、the+比较级……,the+比较级……. 越……，越……

大多数形容词（性质形容词）和副词有比较级和最高级的变化，即原级、比较级和最高级，用来表示事物的等级差别。原级即形容词的原形，比较级和最高级有规则变化和不规则变化两种。 1) 规则变化 单音节词和少数双音节词，加词尾-er，-est来构成比较级和最高级。 构成法 原级 比较级 最高级 一般单音节词 tall(高的) taller tallest 未尾加-er,-est great(巨大的) greater greatest 以不发音的e结尾 nice(好的) nicer nicest 的单音词和少数 large(大的) larger largest 以- le结尾的双 able（有能力的) abler ablest 音节词只加-r,-st 以一个辅音字母 big(大的) bigger biggest 结尾的闭音节单 hot热的) hotter hottest 音节词，双写结 尾的辅音字母， 再加-er，-est "以辅音字母+y" easy(容易的) easier easiest 结尾的双音节词，busy(忙的) busier busiest 改y为i，再加 -er，-est 少数以-er，-ow clever(聪明的) cleverer cleverest 结尾的双音节词 narrow(窄的) narrower narrowest 未尾加-er，-est 其他双音节词和 important(重要的) 多音节词，在前 more important 面加more，most most important 来构成比较级和 easily(容易地) 最高级。 more easily most easily 2) 不规则变化 原级 比较级 最高级 good(好的)/ better best well(健康的) bad (坏的)/ worse worst ill(有病的) old (老的) older/elder oldest/eldest much/many(多的) more most little(少的) less least far (远的) farther/further farthest/furthest as + 形容词或副词原级 + as 1）在否定句或疑问句中可用so… as。 He cannot run so/as fast as you. 2）当as… as 中间有名词时采用以下格式。 as +形容词+ a +单数名词 as + many/much +名词 This is as good an example as the other is. I can carry as much paper as you can.. 3）用表示倍数的词或其他程度副词做修饰语时，放在as的前面。 This room is twice as big as that one. Your room is the same size as mine. 4) 倍数+ as + adj. + as <=> 倍数+ then + of This bridge is three times as long as that one. This bridge is three times the length of that one. Your room is twice as large as mine. Your room is twice the size of mine. 比较级形容词或副词 + than You are taller than I. They lights in your room are as bright as those in mine. 注意： 1）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 clever than his brother. 2）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 countries in Asia. 3）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. It is easier to make a plan than to carry it out. 4）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 large, 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. 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。 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。 many,old 和 far 1) 如果后接名词时， much more +不可数名词 many more +可数名词复数 2) old 有两种比较级和最高级形式: older/oldest 和elder/eldest。 elder，eldest 只用于兄弟姐妹的长幼关系。 My elder brother is an engineer. Mary is the eldest of the three sisters. 3) far 有两种比较级，farther，further. 在英语中两者都可指距离。 在美语中，father 表示距离，further表示进一步。 I have nothing further to say. the + 最高级 + 比较范围 1) The Sahara is the biggest desert in the world. 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。 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. 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. 3) 句型转换： Mike is the most intelligent in his class. Mike is more intelligent than any other students in his class. 4) "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. 和more有关的词组 1) the more… the more… 越……就越…… The harder you work，the greater progress you'll make. 2) more B than A 与其说A不如说B less A than B He is more lazy than slow at his work. = He is less slow than lazy at his work. 3) no more… than… 与……一样……，不比……多 The officials could see no more than the Emperor. no less… than… 与……一样…… He is no less diligent than you. 4) more than 不只是，非常 She is more than kind to us all. 典型例题 1）The weather in China is different from____. A. in America B. one in America C. America D. that in America 答案：D. 本题意为"中国的天气比美国热。"比较的是天气而不是国家，C不能选。A没有名词，后句成分不全，排除。B和D中，B中的one常用来代替可数名词，而that可车以代替不可数或抽象名词，所以选D。 2）After the new technique was introduced，the factory produced ___ tractors in 1988 as the year before. A. as twice many B. as many twice C. twice as many D. twice many as 答案C. 此句意为"这个厂1988能生产的拖拉机是往年的两倍"。 表示倍数用"倍数+ as + 形容词原形+ as +比较对象"的句型。所以此句答案为C。 This ruler is three times as long as that one.
