2.形容词及副词比较级及最高级的定义
大多数的形容词和副词都有三个级别：原级、比较级、最高级。其中比较级表示“更……”，用于两者之间的比较，用来说明“前者比后者更……”，比较级前面一般用much, even, a little修饰，其中even, much 只能修饰比较级。当三个或三个以上的人或事物进行比较时，需要用到形容词（副词）的最高级。表达“……是最……的”,用“the+形容词（副词）的最高级”的结构。后面可以加上表示范围的介词短语或从句。例如：
He is much taller than I. 他比我要高得多。
I jump a little higher than he. 我跳得比他高一点点。
London is the biggest city in Britain. 伦敦是英国最大的城市。
She sings the best in Class Two. 二班她唱歌最好。
二、用法讲解
1. 形容词和副词比较级、最高级的变化规则
（1）规则变化的形容词及副词的比较级和最高级
一般在词尾直接加er或est。
例如：tall-taller-tallest，long-longer-longest
以不发音的字母e结尾的单词在词尾直接加r或st。
例如：nice-nicer-nicest
以辅音字母+y结尾的词，把y变为i，再加er或est。
例如：heavy-heavier-heaviest
重读闭音节，末尾只有一个辅音字母，双写这个辅音字母，再加er或est。
例如：big-bigger-biggest
部分双音节词和多音节词分别在原级前加more构成比较级和most构成最高级。
例如：slowly-more slowly-most slowly；beautiful-more beautiful-most beautiful
（2）不规则变化的形容词及副词的比较级和最高级
原级 | 比较级 | 最高级 |
good/well | better | best |
bad/ill/badly | worse | worst |
many/much | more | most |
little | less | least |
far | farther | farthest |
further | furthest | |
old | older | oldest |
elder | eldest |
2. 比较级和最高级句型：
（1）形容词及副词比较级的句型：
1）比较级＋than...：……比……较为……。即：“A ＋动词＋形容词或副词比较级＋than＋B”。两者相比较，A比B更……一些。例如：
His brother is younger than I（me）. 他弟弟比我年轻。
Beijing is more beautiful than Wuhan. 北京比武汉更漂亮。
【注意】
在比较级前有时可加一些修饰语，如much, a lot, a little, still, even等以示强调或加强语气。例如：
This box is a little heavier than yours.
这个箱子比你的要稍重一些。
This movie is much more interesting than that one.
这部影片比那部有趣得多。
2） as... as：……和……相同。 即：A+动词+as+形容词或副词原级+as+B，表示A和B两者比较，程度相同，“……和……相同”。 例如：
My uncle is as tall as your father. 我叔叔和你父亲一样高。
My dog is as old as that one. 我的狗与那个狗一样大。
3） A＋not＋as＋形容词或副词原级＋as＋B 表示A，B两者程度不同，即“A不如B那么……”。例如：
My uncle is not as tall as your father. 我叔叔不如你父亲高。
Tom is not as honest as John. 汤姆不如约翰诚实。
He can’t run as /so fast as you. 他没你跑得快。
4）“比较级+ and+比较级”或“more and more + 原级（多音节词和部分双音节词）”意为“越来越……”。
例如：
Our city is more and more beautiful. 我们的城市越来越美丽了。
More and more countries begin to save the financial crisis.
越来越多的国家开始拯救金融危机。
5）“the + 比较级，the + 比较级”意为“越……就越……”。例如：
The more you read, the more you know. 你书读得越多，你知道得就越多。
（2）形容词及副词最较级的句型：
1)…one of the +最高级+名词复数，意为“……之一”。例如：
Lu Xun is one of the greatest writers last century.
鲁迅是上世纪最伟大的作家之一。
2)…最高级+of (in/among)…，意为“……之中，最……”。例如：
Of all the movie stars, I think Zhang Ziyi is the best.
在所有的电影明星之中，我认为章子怡是最好的。
3) This is / was + 最高级+名词+that定语从句，意为“这是最……”。例如：
This is the worst film that I have seen these years.
这是我这些年来看过的最不好的一部电影。
3. 形容词和副词的比较级和最高级需要注意点：
（1）当比较级后面有of the two…之类的词语时，比较级前要加定冠词the。例如：
Lucy is the taller of the twins.
Lucy是双胞胎中比较高的那个。
（2）如果后面接名词时，much more + 不可数名词，many more + 可数名词复数。例如：
The farmers have produced much more rice.
这些农夫收了更多的稻谷。
（3）old的比较级形式有older和elder。elder只用于兄弟姐妹的长幼关系。例如：
My elder brother is a famous artist. 我哥哥是一名有名的艺术家。
（4）far的比较级形式有farther和further。一般farther表示距离，而further表示更进一步。例如：
I have nothing further to say. 我没有什么要说的了。
(5) 形容词最高级前必须加定冠词the，但如果最高级前有物主代词、指示代词、名词所有格等修饰时，则不用定冠词。例如：
My oldest daughter is 16 years old. 我最大的女儿16岁。
(6) 形容词最高级常与由介词in或of引导的表示范围的短语连用。若介词后的名词或代词与句中的主语是同一事物时，则用of短语；当只说明是在某一空间、时间范围内的比较时，则用in短语。例如：
This apple is the biggest of all. 在所有的苹果中，这个苹果最大。
He is the youngest in his class. 他在他班里年龄最小。
(7) 形容词最高级前可用序数词限定，共同修饰后面的名词，其结构为：the+序数词+形容词最高级+名词。例如：
Hainan is the second largest island in China. 海南是中国的第二大岛。
(8) 形容词最高级的意义还可以用比较级形式表达。常见的有：
1)形容词比较级+than any other+单数名词。例如：
This book is more difficult than any other book here.
= This book is the most difficult book of all.
这些书当中这本最难。
2) 形容词比较级+than the other+复数名词。例如：
Asia is bigger than the other continents on the earth.亚洲是地球上最大的洲。
(9) 形容词最高级前若有不定冠词a，这时，它不表示比较，而表示“非常”的意思。例如：
Spring is a best season. 春天是一个非常好的季节。
