1.规则变化:
1)加er, est: great--- greater , small---- smaller , clean-----cleaner , fast----faster , long---longer
The bus runs fast.
The car runs faster than the bus.
The racing car runs fastest of the three.
2)以e结尾的直接加r: late--later, fine--finer, nice--nicer,
wide---wider, large--larger
Tom goes to school late.
--Jim goes to school later than Jim.
--Kate goes to school latest in her class.
3)辅音字母加y结尾的, 把y变i加er, est: busy--busier, easy--easier, funny--funnier, heavy--heavier
Mr monkey is busy
-Mr duck is busier than Mr monkey.
-Mr cat is the busiest of all the animals.

big--bigger, red--redder, fat---fatter, thin--thinner

-Lucy is sadder than lily.
-Kate is the saddest in the family.

Which is the most important invention?

6)有些形容词没有比较级:right, wrong, favorite

t;old-older/elder;far
As...as/not so ...as/not as...as
This building looks not so (as) high as that one.
Ms.Sun speaks English as fluently as you.
This room is three times as large as that one.
二、比较级的用法
1. 双方比较,表示一方超过另一方时,用“比较级十than”的结构表示.例如: This pen is better than that one.
2. 表示一方不及另一方时,用“ less十原级十than”的结构表示.例如:
This room is less beautiful than that one.
3. 表示一方超过另一方的程度或数量时,可在比较前加表示程度的状语,如:even,a lot,a bit,a little,still,much,far,yet,by far等修饰.例如:
He works even harder than before.
注意:英语的比较级前如无 even,still,或 yet等时,译成汉语时可用“较”或“……一些”或不译出,一般不可用“更”,如:
She is better than she was yesterday.她比昨天好些了. Please come earlier tomorrow.请明天早点来.
注意:by far通常用于强调最高级.用于比较级时,一般放在比较级的后面,如在前面,应在二者中间加“ the”.如
He is taller by far than his brother.
He is by far the taller of the two brothers.
4. 表示一方随另一方的程度而变化时,用“ the 十比较级(主语十谓语),the 十比较级(主语十谓语)”的结构.例如:The harder he works,the happier he feels.
5. 不与其它事物相比,表示本身程度的改变时,用“比较级十 and十比较级”的结构.例如:
The weather is getting warmer and warmer.
The girl becomes more and more beautiful.
6. 在比较从句中为了避免重复,我们通常用 that(those),one(ones)代替前面出现的名词。

that指物,one既可指人,也可指物.that可代替可数名词单数和不可数名词,而one只能代替可数名词.例如:
The book on the table is more interesting than that on the desk.
A box made of iron is stronger than one made of wood.
7. 表示倍数的比较级有如下几种句型:
A) A is three(four,ete) times the size(height,length,width,ete) of B.例如;
The new building is four times the size( the height) of the old one.这座新楼是那座旧楼的四倍大(四倍高)。

(这座新楼比那座旧楼大三倍[高三倍]).
B) A is three(four,etc) times as big(high,long,wide,etc.) as B.例如:
Asia is four times as lareg as Europe,亚洲是欧洲的四倍大.(亚洲比欧洲大三倍.)
C) A is three(four,etc.) times bigger ( higher,longer,wider,etc.) than B.
例如:Your school is three times bigger than ours,
你们的学校比我们的学校大三倍.(你们的学校是我们学校的四倍大.) 用 times表示倍数,一般只限于表示包括基数在内三倍或三倍以上的数.表示两倍可以用 twice或 double
三、最高级的用法
1. 三者或三者以上相比,表示最高程度时,用“ the十最高级”的结构表示.这种句式一般常有表示比较范围的介词短语.例如:
Zhang Hua is the tallest of the three.
He works (the) hardest in his class.
2. 最高级可被序数词以及 much,by far,nearly,almost,by no means,not quite,not
really,nothing like等词语所修饰. 例如:
This hat is by far/much/nearly/almost/not nearly/by no means/not quite/nothing like the biggest.
How much did the second most expensive hat coat?
3. 表示“最高程度”的形容词,如 excellent,extreme,perfect等,没有最高级,也不能用比较级.
4. 形容词最高级修饰作表语或介词宾语的名词、代词时,被修饰的词往往省略. He is the tallest(boy) in his class.
5. 作状语的副词最高级前可以不加定冠词.例如
0f all the boys he came(the) earliest.
