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
以不发音的字母e结尾的词加-r nice-nicer
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
+er
+r
变y为i+er
双写末尾辅音字母+er
词前+more
设计意图
通过学生感知发现并自主总结形容词副词比较级的变化规律。
巧学妙记
直 去 双 改 多
比较级构成的规则变化
比较级不规律,一般词尾加er；
词尾若是哑音e,直接加r就可以；
单一辅音单音节,双写词尾加er； 辅音加y很重要,去y变i加er；
双多音节字太长,前加more来比它强。
巧学妙记

比较级构成的不规则变化

good/well better
bad/badly/ill worse
many/much more
little less
old older/elder
far farther/further
一分为二有两个，
一是远来一是老，
合二为一共三对，
坏病两多并两好。
还有little含双意，
只译少来不译小。

快速说出下列形容词或副词的比较级
巩固练习
Is Tom smarter than Sam No, he isn't. Sam is smarter than Tom.
Is Tara more outgoing than Tina No, she isn't. Tina is more outgoing than Tara.
Are you as friendly as your sister No, I'm not. I'm friendlier.
Does Tara work as hard as Tina Yes, she does.
Who's more hard-working at school Tina thinks she works harder than me.
Underline the adjectives
Circle the adverbs.
Tips: 形容词与be动词连用；
副词修饰行为动词，往往位于动词之后。
Is Tom smarter than Sam No, he isn't. Sam is smarter than Tom.
Is Tara more outgoing than Tina No, she isn't. Tina is more outgoing than Tara.
Are you as friendly as your sister No, I'm not. I'm friendlier.
Does Tara work as hard as Tina Yes, she does.
Who's more hard-working at school Tina thinks she works harder than me.
Grammar Focus
as+原级+as“与......一样”用来进行同级比较。
I wish my family will be as healthy as before in 2021.
Tips: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。
形容词和副词的同级比较
Is Tom smarter than Sam No, he isn't. Sam is smarter than Tom.
Is Tara more outgoing than Tina No, she isn't. Tina is more outgoing than Tara.
Are you as friendly as your sister No, I'm not. I'm friendlier.
Does Tara work as hard as Tina Yes, she does.

形容词和副词的比较级常用结构
比较级+than
Tips: 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。
I'm taller than last year.
I play basketball better than I (did) last year.
A + be + 形容词比较级 + than + B
A + 实义动词 + 副词比较级+ than + B
设计意图
学生自主观察--发现--思考--总结规律 ：
1.“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。
The harder we are, the better grades we will get.
特殊结构
Grammar Focus
I wish our country will be stronger and stronger.
I think my school will be more and more beautiful.
2.“The + 比较级, the + 比较级” 意为 “越……，越……”。
Find the differences
比较级and比较级
“越来越......”
stronger and stronger
more and more important
the+比较级...the+比较级
“越......越......”
The harder we are, the better grades we will get.
The more, the better. 越多越好.
and前后都一样，表示程度越来越强
the前the后不一样，因果关系要牢记
中考常见可修饰比较级的词
总结：当表示一方超过另一方的“程度”时，可以用much, even, still等来修饰。
饭饭修饰比较级
