形容词比较级的用法
1. 同级比较
两个比较对象程度相同时,用“as+形容词原级+as的结构”
例如： Tom is as tall as his brother.
My hair is as long as mine.
在这两种结构中,第一个as是副词,而第二个as是连词；在第二个as的后面接名词、句子或代词的主格（一般不要接代词的宾格）.例如：
His bedroom is not as big as his sister's.
It is not so hot as yesterday.
[学生两人一组使用as… as… 及 not as(so) … as…练习同级比较.]
2、在比较级 + than的结构前可以加上某些副词类的词,以对其进行修饰,如：far（远）,even（甚至）,much（许多）,still（更,还）,a lot（许多）,a little / bit（一点）,rather（相当地）,等等.例如：
She’s a little more outgoing than me.
My bike is much newer than his.
3、 比较级中的两个特殊作用的结构是：
a. The + 比较级 + 句子,the + 比较级 + 句子 .它表示的意义是"越（怎么样就）越（怎么样）",在这个结构中的两个"比较级"不要求一定词性相同,它们各自的词性要依句子的需要而定.例如： The harder you work at your study, the better grades you will have. 你学习越努力,你的成绩就越好.
The more we get together, the happier we’ll be.
朋友越多, 我们就越高兴.
[Ask and answer in groups to make some new sentences.]
b. 比较级+ and + 比较级.它表示的意义是"越来越（怎么样）",在这个结构中的两个 "比较级"则要求词性相同.例如：
Our country becomes more and more beautiful.
When spring comes, the weather is warmer and warmer.
4、 比较对象中一方不及另一方时,用“not as(so)+形容词原级+as ”或“less+形容词原级+ than”的结构.
He is not as careful as his sister. == He is less careful than his sister.
== His sister is more careful than he.
[Ask and answer in groups to make some new sentences.]
5、 在两者之中选择“较为、、、 ” 的一个, 比较级之前加the.例如：
Amy is the taller of the two girls.
Of the two books, the one on the right is the better.
