形容词和副词的比较等级
大多数形容词和副词有三个等级：
1. 原级，即原形。e.g. good; fast; outgoing...
2. 比较级，表示“较……” 或“更……一些”。 e.g. better; faster; more outgoing...
3. 最高级，表示“最……”。 e.g. best; fastest; most outgoing...
比较级构成的规则变化
单音节词和部分双音节词 一般在词尾加-er tall-taller
high-higher
以字母e结尾的词加-r fine-finer
wide-wider
重读闭音节词词尾只有一个辅音字母时，先双写该辅音字母，再加-er hot-hotter
big-bigger
以“辅音字母+y”结尾的双音节词，变“y” 为 “i”，再加-er lazy-lazier
happy-happier
多音节词和部分双音节词在其前面加more interesting-more interesting
popular-more popular
比较级构成的不规则变化

不表示职务地位资历 可表示职务地位资历更高
更口语化 更正式

Tom, you need to be polite. They are all our elders(n. 长辈).
易混辨析
farther与further
farther 表示距离上更远。
e.g. I have to walk farther to work now.
further 即可表示距离上更远，也可表示程度上或抽象意义上的更深远或更进一步。
e.g. Let's consider this point further.
further 还可作动词，表示“促进；增进”。
e.g. She took the new job to further her career.
比较级常用句型
比较级+than
A + be + 形容词比较级 + than + B
A + 实义动词 + 副词比较级+ than + B
注意：than前后所使用的动词相同时，通常用助动词代替后面的动词或省略后面的动词。
Tom is taller than me.
Tom runs faster than me (do).
比较级常用句型
◆“the + 比较级 + of the two” 意为 “两者中比较……的”。
English is becoming more and more important.
◆“比较级 + and + 比较级” 或 “more and more+ 形容词/副词原级”，表示 “越来越……”，其后均不可接than。
After the new year, the day is becoming warmer and warmer.
◆“The + 比较级, the + 比较级” 意为 “越……，越……”。

比较级常用句型
◆“Which/Who... + 比较级, A or B ” 表示 “A和B，哪一个/谁更……？”
Who is taller, Jim or Tom
◆“A...+ 倍数 + 比较级 + than + B” 表示 “A是B的多少倍”。

◆“比较级 + than any other + 可数名词单数” = “比较级 + than the other + 可数名词复数”，表示“比其他任何/所有……都……”。该句型在同一范围内进行比较。
China is larger than any other country/the other countries in Asia.
可修饰比较级的词
当表示一方超过另一方的“程度”时，可以用much, a lot, a little, a bit, even, far等来修饰形容词比较级。注意：比较级不能用very, so, too等修饰。
He is much more serious than his brother.
This book is even more useful than that one.
Can you come to school a little earlier tomorrow morning
巧学妙记：两多(much, a lot)两少(a little, a bit)一甚至(even)，还有一个远（far)去了。
比较级的注意事项
1）比较对象必须一致。
My hair is longer than yours.
2）有时为了避免重复，可用that或those代替前面提到的词，而且that或those不能省略。
The weather in Hainan is warmer than that in Beijing.
His stories are more interesting than those I told.
yours相当于your hair
用原级表示比较级的句型
as...as 与……一样……
as...as用来进行同级比较，中间要用形容词或副词的原级。
This movie is as moving as that one.
同级比较用原级，as...as永不离。若是否定加not，后者总是强前者。
as...as的否定结构是not as/so...as，意为“不如……那样……”。
My sister is not as/so outgoing as me.
形容词、副词的最高级
形容词、副词的最高级用于三个或三个以上的人或事物之间的比较，常用of / in短语来说明比较的范围。
形容词最高级前要加定冠词the，副词最高级前的the可省略。

Putting It All Together
Ⅰ. Read the passage and answer the questions.
China Rising at the Winter Olympics
Fewer countries take part in the Winter Olympics than in the Summer Olympics. It's easy to understand why. In many countries, the weather is too hot for sports such as skiing and skating.
China is a newcomer to the winter games. In 1980, China sent athletes to the Winter Olympic Games for the first time.
At the 1992 Winter Games, Chinese speed skater Ye
Qiaobo won China's first Olympic medals—silver in
the 500- metre and in the 1 000- metre speed -skating events.
China is now a world power in speed skating. Yang Yang won China's first gold medal in the 2002 Winter Olympics. China is also strong in figure skating. At the 2010 Games in Vancouver, Canada, China finally won gold and silver medals in pair skating. This made China the undisputed champion of the event.
1. Why do fewer countries take part in the Winter Olympics
2. When did China first send athletes to the Winter Olympics
3. Who won the first gold medal for China in the Winter Olympics
Because in many countries, the weather is too hot for sports such as skiing and skating.
In 1980.
Yang Yang.
Ⅱ. Write, Draw and Guess.
Divide the class into two teams.
Each team needs ten blank cards. On each card, the teams write a sentence using comparative or superlative adjectives or adverbs. (For example: This tree is bigger than the other one. This pencil is the longest. )
The two teams trade their cards. One by one, the team members draw pictures on the blackboard to represent their sentences. The teammates try to guess what the sentence says.
The team that gets the most correct answers wins!
