形容词和副词的比较级和最高级
一、形容词和副词的比较等级形式
大多数形容词和副词有比较级和最高级的变化，事物的等级差别。原级即形容词和副词的原形，两种。
（1）规则变化：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。即原级、比较级和最高级，用来表示比较级和最高级有规则变化和不规则变化
构成法
一般单音节词末尾加
原级
-er,-est。tall(高的)
great(巨大的)
比较级taller greater nicer larger abler bigger hotter
最高级tallest greatest nicest largest ablest biggest hottest
以不发音的只加-r,-st 。
e结尾的单音节词
nice(好的) large(大的) able（有能力的) big(大的) hot热的)
和少数以- le结尾的双音节词
以一个辅音字母结尾的闭音节单音节词，双写结尾的辅音字母，再加-er，-est 。“以辅音字母+y” 结尾的双音节词，改y为i，再加-est 。
少数以-er，-ow结尾的双音节词末尾加-er，-est 。其他双音节词和多音节词，在前面加more，most 来构成比较级和最高级。
easy(容易的)
easier busier
easiest busiest
-er，busy(忙的)
clever(聪明的) narrow(窄的)
cleverer narrower
cleverest narrowest
important(重要的) more important most important easily(容易地)
more easily
most easily
（2）不规则变化
原级
good(好的) / well(健康的)
比较级better
最高级best worst most least oldest/eldest 最老的/最年长的farther/further
+ as
ill(有病的) / bad (坏的)/ badly (坏地) worse much/many(多的) little(少的) old (老的) far (远的/地)
二、形容词和副词比较等级的常用句型。
1）在否定句或疑问句中可用
more less older/elder 比较老的/较年长的farther/further
（1）as + 形容词或副词原级

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
This is as good an example as the other is.
as的前面。
- as + many/much +名词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
- 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. （2）比较级形容词或副词+ than - You are taller than I.
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. （3）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, even2）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 timeB. a more happier time C. much happiest timeD. a much happier time
答案：D。

重点难点详解（1）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
- 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。（2）the + 最高级
+ 比较范围
the，副词最高级前可不用。
“非常”。
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
形容词most前面没有the，不表示最高级的含义，只表示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
注意：
a. very可修饰最高级，但位置与- This is the very best. - This is much the best. b. 序数词通常只修饰最高级。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. （3）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 = less A than B 与其说A不如说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.
- Africa is the second largest continent. much不同。
- This hat is nearly / almost the biggest.
I have nothing further to say.
