形容词和副词的比较级：
1、定义：
大多数形容词有三个级别：原级、比较级、最高级。

其中比较级表示“更.....；较......”，用于两者之间的比较。

2、形容词和副词的比较级构成：
（1）规则变化：
①一般在词尾加-er：tall-taller loud-louder
②以不发音的e结尾，在词尾加-r：nice-nicer late-later
③以“辅音字母+y”结尾，双写最后一个字母，再加-er：
big-bigger wet-wetter thin-thinner
④多音节和部分双音节，在词前加-more
outgoing-more outging clearly-more clearly
(2)不规则变化：
good/well-better bad/badly-worse
many/much-more little-less
far-farther/further old-older/elder
3.比较级常用句型结构：
(1)A+be+形容词比较级+than+B
A+实义动词+副词比较级+than+B
eg:Tom is shorter than Jim.
Tom runs faster than Jim.
(2)the+比较级+of the two意为“两者中更......的一个”
Tom is the taller of the two boys.
(3)“比较级+and+比较级”或“more and more+原级”意为“越来越......"

(4)”The+比较级，the+比较级“意为”越......;越......"

(5)表示两者进行比较，并进行选择，常用句型：疑问词+be/do+形容词比较级，A or B?"
Which book do you like better,this one or that one?
Which is bigger,the erarth or the moon?
4.常见的修饰比较级的词语有：两多“much,a lot",两少”a bit,
a little",两甚至：“even,still",还有一个远去了”far"。

This book even more interesting than that one.
Can you come here a little earlier tomorrow?
注意：
The weather in Beijing is colder than that in Guangzhou in winter.
The students in our class are much more
outgoing than those in your class.
为了避免比较对象在同一句中反复出现，that指代比较对象为单数和不可数名词的，those指代可数名词复数。
