教学步骤：
一.学生看教材P.119 ，并完成下列小结
（一）形容词比较等级的含义 ：形容词有________,_________,_________,三个比较等级。
1. 原级（原形）如：他的头发很长。His hair is very ___________.
2. 比较级：表示“较…” 或“更…些”。
如：我的头发比他的长。My hair is ________ ________his.
健康比财富更重要。Health is __________ _________than wealth.
3. 最高级：表示“最…”
如： 快乐是最好的药。Happiness is the ____________ medicine.
（ 二）.形容词比较级、最高级的构成规则
单音节词和部分双音节词的构成方法：
1.一般在词尾加_________或_______，
如：small---smaller---smallest, long---_________--__________
2.以字母_____结尾的词加____或______,
如：large-larger---largest, nice---__________ -____________
3.以重读闭音节结尾并且末尾只有一个辅音字母的应先__________,再加________ 或__________.
如；big----_______--__________; fat-________-__________
4. 以辅音字母 + y结尾的，先变y为___，再加___或______.
如：heavy---___________-__________
多音节词和部分双音节词的构成方法：
在原级前加______________ 或 __________________，
如popular,-more popular-most popular
Interesting-______________ -__________________
特殊的：good/well---- better best bad/ill --- worse worst
Manny/much--- more most little ---- less least
far---- farther/further 或 further/furthest
old – older/elder---oldest/eldest
（三）. 形容词比较级、最高级的用法
1.学生小结
2.教师点拨
比较级：A +比较级 + than + B （A.B不能相互包括；A比B在某方面程度更高）
如：猫比其他动物更可爱。 Cats are more lovely than other animals.
最高级：A +the +最高级 +in/of（A在某方面程度最高 ,）
注：A应在那个范围内程度最高
误：Tom is the tallest of all his classmates.
※同级比较: A=B A + as + 原级 + as + B 表示A.B在某方面程度一样。
如：圣诞树几乎和房间一样高
The Christmas tree is as tall as the room.
A不如 B A not as/so+原级+as + B 表示A在某方面不及B，此类句型可以改为比较级形式。
如：他没有我高。He is not as (so) tall as I/me.
=He is shorter than I/me.
这个男孩不如那个男孩细心。
This boy is not as careful as that boy.
=This boy is less careful than that one.
=That boy is__________________________.
二.比较结构中应注意的七个方面见教材P.120
1.比较级与最高级可以转化
如：在中国，长江比其他任何河流都长。
The Yangtze River is _______than any other river in China.
= The Yangtze River is _____ ________ river in China.
2.当某一事物与其他事物作比较时，被比较事物中不能包括本身。
Eg1.他比班上其他学生高。
He is _______ than any ________student in his class.
Eg2.上海比湖北任何一个城市都大。
Shanghai is __________ than ________ ________ city in Hubei.
3.如果比较对象相同，可用 that/those 代替第二个对象。
Eg1：重庆的天气比上海的天气要好。
The weather in Chongqing is better than that in Shanghai.
Eg2:第二册的课文比第三册的容易得多。
The texts in Book2 is much easier than ________in Book3.
4.两个比较级用and 连接，表示“越来越…”
(e.g) bigger and bigger 越来越大
more and more beautiful 越来越美
5.the + 比较级，the + 比较级，表示“越….越…..”
越多越好。The more ,the better.
你练得越多，做起来就变得越容易。The more you practice , the easier it becomes.
6.表示“两者较…..”时，用 “the + 形容词比较级 + of 短语”来表达
他是两人中较高者。He is the taller of the two.
7、形容词的比较级可以用much , a little , a lot ,even ,three years, third, twice等修饰，使原来的比较级在语意上更加明确，
vv如: 鸡要比奶牛小得多。Chickens are much smaller than cows.
我比你大点。I am a little older than you.
8..one of + 最高级+单数名词 表示“最…之一”
One of the most famous rock bands
9..序数词+最高级+单数名词 表示“第几…”
如：我是班上第三高的男生。I’m the third tallest boy in our class.
10..最高级前面要加 the ，但最高级前有指示代词，物主代词或名词所有格修饰时，其前不能再加the
(e.g) 这是我最好的一本书。This is my best book.
