形容词和副词的比较等级详解（适合初、高中使用）大多数形容词和副词有三个等级：⑴原级，即原形。
⑵比较级，表示“较……”或“更……一些”的意思。
⑶最高级，表示“最……”的意思。
一、原级的构成和用法1、构成：形容词和副词的原级形式是形容词和副词的原形。
2、用法：表示双方在程度、性质、特征等某方面相等时，用“as＋原级形容词或副词＋as”的结构；表示双方不相等时，用“not so（as）＋原级形容词或副词＋as”的结构；表示一方是另一方的若干倍时，用“倍数＋as＋原级形容词或副词＋as”的结构。
例如：Xiao Wang is as tall as Xiao Liu.This building looks not so（as）high as that one.Mr. Sun speaks English as fluently as you.This room is three times as large as that one.二、比较级和最高级的构成和用法（一）比较级和最高级的构成：1、单音节形容词以及少数以-er, -ow结尾的形容词和副词加“er”,“est”。
例如：2、以e加“r”,“st”。
例如：3、以一个辅音结尾的单音节形容词，其前的元音字母发短元音时，该辅音字母要双写，然后加“er”,“est”。
例如：4、“er”,“est”。
例如：5例如：6、少数单音节形容词也加more和most构成比较级和最高级。
例如：7、下列形容词、副词的比较级和最高级可有两种构成方法。
81、双方比较，表示一方超过另一方时，用“比较级＋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＋原级＋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，可在比较级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。

每节课的一开始我都会安排学生以小组为单位进行Role-play。
学生对学习英语较热情，并有预习的习惯，对本节课的知识有所了解。
二教材分析1. 单元教材分析本单元是九年制义务课程标准实验教科书《新目标英语》八年级上册中第三单元，本单元的核心话题是谈论人的个性特征（Talk about personal traits）比较人物与事物特征（Compare people and things)。
通过对本单元的学习，学生能掌握本单元出现的比较人与事物的词组及句型。
教学设计:1 、新课导入:老师以图片呈现的形式让学生用形容词比较图片中人物的外貌。
分别引出tall, short, fat, thin,long, pretty, beautiful ，good 等形容词。
2 、新知学习:1 )词语变形老师利用刚才的图片以及学生所给出的形容词来运用比较级的句子描述图片中人物的不同。
采用分类呈现的方法，把比较级的书写规律直观地展示给学生。
a. Tom is taller than Nick.Nick is shorter than Tom.b. Ann is fatter than Mary.Mary is thinner than Ann.c. Lucy is prettier than Eva.d. Lucy is more beautiful than Evae. Amy is better in school than Lily.然后趁热打铁，总结比较级的构成规律。
先试着让学生自己发现规律进行归纳，然后老师再进行点评总结。
形容词比较级的变形规律是本节课的学习难点，因此讲解的时候应适当放慢速度，照顾大多数学生的学习感受。
在学生已经掌握了形容词的变化规律后，通过练习加深记忆，检验学习效果。
本部分老师准备了单词卡片，这些单词是常用的形容词。
把学生分成男女生两组，当老师出示每一张卡片的时候，学生进行小组抢答，给出形容词的正确比较级变形。
2 )句型使用形容词比较级的句型是本课的另一个教学重点。
把学生的注意力重新引领到导入部分的图片句子中。
让学生观察这五组句子的结构的相同点，总结出比较级的句型特点，并强调在句子中形容词比较级前面的be 动词和后面的than 不能漏掉，这是学生在句子中经常犯的错误。
老师应鼓励学生积极思考，自己发现知识点，这样他们就会很有发言的积极性。
并且课堂上能够主动发现新知，问题回答得漂亮的同学，老师都会当场给予加星星的奖励。
3. 巩固练习两人一组，每组得到一张画有图案的卡片，学生要根据图片想出正确的形容词，并用一个比较级的句子描述图片内容。

八上英语第六单元
（形容词、副词比较级经典材料）
初中英语中的比较用法
一、形容词、副词比的较级：
1、一般：加er、如：calmer、stronger、longer等
2、以e结尾的为了避免重复e，就直接加r，如 nicer、finer
3、以辅音字母(A 到 Z 除掉 A, E, I O, U, 一共 21 个)加y结尾的，把y改成i+er，如
heavier、
4、以重读闭音节(单个元音字母后面有辅字组（r w y 除外）且以辅字组big,top,stop)结
尾的，双写末尾辅音字母再加er，如bigger、thinner等
5、多音节和部分双音节的形容词、副词的比较级：前面加more，如：more interesting
等
6、规则变化
good/well---better;bad/ill---worse;much/many---more;little--less;far--farther/f
urther
用法拓展：
一、Even（甚至）、a little、a bit ：略微，一点，much、a lot 、far等程度词+比较
级
如 ：much stronger中much+stronger（比较级）；a little taller （比较级）
a lot more fun ：fun的比较级为 more fun 所以 a lot +比较级
二、比较级的用法用than引出比较的对象
如 he is more interested in PE than Chinese 中than 引出比较对象Chinese （语文）
注意：有了than（比）就要跟比较的对象，且比较的对象之间要相一致
如： He has more books than Jim （对） he 和Jim 是一致的：人与人比较，
His books are more than Jim (错)因为 His books 与Jim 不一致，故要改成Jim's
books/Jim's
三：than引导比较时，有重复的成分，可以省略，不省略时用助动词代词
如： He has more books than Jim （does）这个does就是指代has，
因为重复出现，故省略，不省略时，应该用does
He is more ethletic than Jim （is）也是同理
四：than 后面可以加代词的宾格、也可以加代词的主格
He has more books than her（宾格）
He has more books than she（does）主格
五、无需引出比较对象时，就不用than，反之。有了than，就要有比较的对象
比较级的特别用法：
1、more and more，越来越。。。。（more指代形容词或副词的比较级，下同）
2、the more，the more ：越。。。越。。。。
3、less 、more都可跟部分双音节或多音节形容词或者副词构成比较级，两者意刚好义相
反
4、the more of the two ：两者中更。。。的一个，
如 the taller of the twin brothers 双胞胎兄弟中更高的一个
比较级易错题：
Who is good at PE，Tom or Jim good改成better（看到or想到比较级）
She is a little outgoing than me outgoing 改成more outgoing
This box is much heavy 。Heavy 改成heavier
John's homework is much more than Jim 。Jim 改成Jim's
（看到 a little、a lot、much、even、far想到比较级）
He has much more homework than I （do）对
He has much more homework than me(对）
He has much more homework than me do错
（than后可跟主格，省略助动词，如例句1中的do；也可以跟宾格，但是后面没有助动词）
I have few books than you 。Few 改成fewer
He does much work than me。Much改成more
（看到than，就用比较级）
My hair is longer than her 。Her改成hers=her hair
（比较的对象要一致，my hair 不能跟she 比较）
注意：very、too 、quite、so、as。。as只跟形容词、副词的原级，不跟比较级。
二、as ....as的形容词或者副词的原级比较，第一个as是副词，第二个as是连词，如：
1、He is as tall as Jim （is）
2、He is as good at PE as anyone else（is）（任何一个其它人）
3、He has much money as she （ does）
否定形式：not as 。。。as 或者not so 。。。As。。。或者never/seldom/hardly so/ as 。。
As
如 He is not so/as tall as Jim （is）
He doesn't have so/as much money as she （ does）
He never runs so/ as fast as Jim does
三、倍数的比较，经典例子：half an hour，half(倍数词) 为：半倍，an hour：名词
即：倍数词+名词：构成倍数的比较，
常见的倍数词用time（可数）；two times =double：双倍、两倍；half：半倍，一半
表示大小、尺寸的名词：size、width（宽度）、length（长度）、height（高度）,weight
（重量）
This room is three times the size of that one 。这个房间的大小是那个房间的三倍。
The book is double（=two times）the weight of that one 。这书的重量是那本书的两
倍。
拓展一、倍数词+as....as结构
This room is three times the size of that one 。这个房间的大小是那个房间的三倍。
=This room is three times as big as than that one。这个房间的大小是那个房间的
三倍大。
The book is double（=two times）the weight of that one 。这书的重量是那本书的两
倍。
=The book is double（=two times）as heavy as that one 。这书的重量是那本书的两
倍重。
拓展二、倍数词+比较级
This room is three times the size of that one 。这个房间的大小是那个房间的三倍。
=This room is three times bigger than that one 。这个房间比是那个房间大两倍。
The book is double（=two times）the weight of that one 。这书的重量是那本书的两
倍。
=The book is one time heavier than that one 。这本书比那本书重一倍
