回答1：

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。

4 以一个元音字母加一个辅音字母结尾的重读闭音节的形容词
双写最后一个字母+er +est

slim，thin，red，hot，fat，wet，sad，glad都是这样
5.分词形容词（-ed&-ing结尾的adj.)意思就是以ed或ing结尾的形容词
比较级 more~~ 最高级 most~~~~
例：tired more tired most tired
6 多音节形容词（含三个或三个以上元音的单词）和部分双音节形容词（polite，often，初中阶段大概就这两个）
比较级 more~~ 最高级 most~~~~
例：beautiful more beautiful most beautiful
7 特殊变化
good/well better best
little less least
bad/ill worse worst
many/much more most
old older(无血缘关系）/elder(有血缘关系） oldest/eldest

Ps：看我打的这么辛苦，也该选我吧~~~
