一、 1、形容词比较级在句子中的运用：两个事物或人的比较用比较级，比较级后面一般带有单词than。
比较级的句子结构通常是：
sth 动词be (am , is , are ) 形容词比较级 than（比） sth ,
eg.： I'm taller and heavier than you. （我比你更高和更重。）
An elephant is bigger than a tiger. （一只大象比一只老虎更大。）
* 比较级前面可以用much, a little 来修饰表示程度,
* than后的人称代词用主格（口语中可用宾格）。
2．形容词加er的规则：
① 一般的直接在词尾加er ，
Eg. tall - taller , strong - stronger ,
② 以e结尾的，直接加r eg. fine - finer ,
③ 以辅音字母加y结尾的，先改y为i再加er，
eg.funny - funnier
④以一个元音字母和一个辅音字母结尾，双写最后的字母再加er，
eg.big--bigger, thin--thinner ,hot–-hotter，
sad--sadder，fat—fatter
3．不规则形容词比较级： good--better,
4.多音节词变比较级，单词不变，词前加个more即可
beautiful--more beautiful， expensive--more expensive
二、副词和副词比较级
1.形容词与副词的区别 (有be用形，有形用be；有动用副，有副用动)
⑴在句子中形容词一般处于名词之前或be动词之后。
⑵副词在句子中最常见的是处于实义动词之后。
2．副词比较级的变化规则基本与形容词比较级相同
三、平级
1、比较的两者应该是互相对应的可比较的东西。
典型错误：My hair is longer than you.（我的头发比你更长。）
比较的两者是我的头发、你（整个人），那么比较的对象就没有可比性。
应该改为：My hair is longer than yours.
或My hair is longer than your hair.
- 如果比较的两者是一样的时候，我们会用 as…as…这个词组。
- 它的用法是：
什么 be as 形容词原形 as 什么，意思是什么和什么一样……
Eg： I'm as tall as you.（我和你一样高。）
My feet are as big as yours.（我的脚和你的一样大。
- 识记掌握常用形容词的比较级变化
- 能够识别比较级句子
- 区分单音节词和多音节词变比较级的区别
一、写出下列形容词的比较级
old__________ young________ tall_______ long________ short________
strong________ big________ small_______ fat_________ thin__________
heavy______ light_______nice_________ good_________
beautiful_________________ low__________ high_________ slow_______
二、根据句意填入单词的正确形式
1. My brother is two years __________(old)than me.
2. Tom is as ________(fat) as Jim.
3. Mary’s hair is as __________(long) as Lucy’s.
4.Ben ______ (jump) ________ (high) than some of the boys
in his class.
5._____the girls get up_______(early) than the boys?
No,they______.
答案：一、older younger taller longer shorter stronger bigger smaller fatter thinner heavier lighter nicer better more beautiful lower higher slower
二、1. older 2.fat 3.long 4.jumps higher 5.Do earlier don’t
解析：一、old young tall long short strong small
light high low slow属于直接加er型
Big fat thin 属于重读闭音节类型，需要双写最后一个字母，加er
Heavy 属于以辅音字母加y结尾类型，需变y为i加er
Nice 属于 以单独的不发音字母e结尾直接加r类型
Good 属于不规则变化类型，变为better
Beautiful 属于多音节词（bea-u-ti-ful） 变比较级在此词前加more 词
二、1.信号词是than（比），句意是我的哥哥比我大2岁，可判断用old的比较
级形式，判断old为直接加er类型，故older。
2.信号词as......as(......和......一样)，句意：Tom和Jim一样
胖，故fat用原级
3.道理和2一样，用原级，long。
4.Ben属于第三人称单数，故jump用第三人称单数形式，jump变三单加s，
用than（比）判断用high的比较级，high直接变比较级加er；本题除
了考查比较级以外，还考查学生能否判断识别出三单概念。
5.get up属于实意动词类型，对应的一般疑问句首单词用Do，对应的否定
回答用No，they(代指the girls) don’t.回答，than可判断出early
用为比较级形式（注意early为副词，变化方法和形容词一样）；本题考查
一般疑问句问答和比较级辨别和应用。
