第五讲 形容词原级与比较级

1、My cousin runs ________(fast) than me.

（2）在否定结构中既可以用as……as……结构，也可以用so……as结构，表示“……不如、不及……”。

如：

He isn’t as/so tall as you.他不如你高。

He cannot run so/as fast as you.他没你跑得快。

1、I can play basketball _____________you.我的篮球打得比你好。

4、形容词和副词的比较级用法

比较级用于两者的比较，其结构是：比较级+than。当than前后使用的动词相同时，通常用助动词代替后面的动词，该动词或助动词可以省略。如：

You look much younger than I (do).你看上去比我年轻多了。

Bruce drives much more carefully than you.布鲁斯开车比你小心多了。

1、Jack did__________Bruce.杰克比布鲁斯做得好。

1、比较级的特殊形式

（1）“比较级+and+比较级”意为“越来越……”，表示事物本身程度的逐渐增长。如：

China is becoming stronger and stronger.中国正变得越来越强大。

He runs faster and faster.他跑的越来越快。

（2）“the+比较级，the+比较级”意为“越……就越……”，表示一方的程度随着另一方的变化而变化。如：The more careful you are,the fewer mistakes you’ll make.你越认真，你犯的错误就越少。

（3）表示“两者之间最……的一个（of the two）”时，常用“the+比较级”结构。如：

Mary is the taller of the twins.玛丽是双胞胎中较高的那个。

2、注意力比较范围

比较级要避免与自身进行比较，若比较的对象属于同一范围，要用“比较级+than any other+单数名词”或“比较级+than anyone/anybody/anything else”,表示“比其他的任何……都……”。如：

Lin Tao is taller than any other student in his class.林涛比他班级里的其他同学都高。

Jack studies harder than anyone else in his class.杰克比班上其他同学学习刻苦。

3、比较级的修饰

修饰比较级常用的词和短语主要有much,even,any,yet,far,a lot,a little,a bit,twice,five times,many times等。如：Are you feeling any better today?你今天感觉好多了吗？

He is ten years older than I。他比我大十岁。

He speaks Chinese a lot better than before.他说的中文比以前好多了。
