【教师寄语：请你相信，态度决定高度！】

比较级

【基础知识】

一、比较级的意义：两个人或物之间的比较。表示“较……”或“更……一些”。标志词：than (比）

其基本结构：A + be动词+ 形容词比较级+ than + B

He is younger than me.他比我年轻。

The cup is smaller than the desk.这个杯子比桌子小。

三、重难点、考点。

1、形容词/副词比较级前的修饰语.

(1)much/a little/ a bit/ a lot / slightly.

She is much taller than me.

I am a little shorter than my mother.

(2) 具体数量.

My sister is ten years younger than me.

(3) any/ no/ even/ some/ still

Do you feel any better today?

She is no older than mike.

2、定冠词或指示形容词+比较级+名词表示比较。

The taller boy is John.

3、不可使用双重比较级。

错误My mother is more younger than my father.我妈妈比我爸爸小。

正确My mother is younger than my father.

4、与than搭配的词语形式。

（1）名词/代词He is older than me.

(2) 动名词/从句Skiing is more exciting than skating.

5、as……as中间用原级。

as……as… (与…一样）

not as(so)……as（与…不一样）

6、表示倍数的词或其他程度副词做修饰语，放在as的前面。

She can read twice as fast as you do.

7、、比较级与最高级可以转换，意思不变。如：

She is taller than any other girl in Class5.=She is the tallest girl in Class5.

8、比较的事物只能是同一级别的。如：

My hair is longer than Mary's.

His shirt is more expensive than mine.

9、如果比较对象相同，可用that\those代替第二个比较对象。如：

The weather in Shanghai is better than that in Wuhan.

10、比较级的特殊搭配。

1）“比较级+and+比较级”表示“越来越……”eg: He becomes fatter and fatter.

2）“The +比较级…，the +比较级”表示“越……，越……”The more ,the better.

3）表示两者中”较……“时，用the + 形容词比较级+ of 短语来表达。He is the taller of the two.

4）More than 不仅仅是，超过；Less than 不到

5）more or less 差不多The work is more or less finished.工作差不多完成了。
