语法：比较级，四种时态

形容词比较级与最高级

一．比较级

当我们需要对事物做出比较时，需用到比较级。 1.比较级的标志词：than,or,of the two 2.比较级的结构：

主语+动词be（am/is/are）+形容词比较级+than(比)+其他 如： I am taller than you.我比你高。

He is the taller of the two.他是两个中最高的。

Which one do you like better,apple or orange.苹果和橙子你更喜欢哪一个？

二．比较级的变化规则

形容词的比较级是在形容词的基础上变来的，它的变化规则是： 1.一般的直接在词尾加er. 如：tall---taller long---longer 2.以e结尾的直接加r. 如：nice----nicer

3.以辅音字母加y结尾的，直接把y改为i再加er. 如：happy---happier heavy—heavier

4.以重读闭音节结尾的，双写末尾的辅音字母再加er. 如：big---bigger,hot—hotter,thin—thinner

除此之外，还有几个词的比较级是不规则变化的，如： many/much(原形)-----more(比较级)------most(最高级)

little/few(原形)-------less(比较级)------- least(最高级)

good/well(原形)-----better(比较级)------best(最高级)

bad(原形)----worse（比较级）-------worst(最高级)

far(原形)----farther/further（比较级）-----farthest/furthest(最高级)

old(原形)----older/elder（比较级）-----oldest/eldest(最高级)

【注】形容词最高级的变化类似于比较级，只是把词尾的er改为est.而且特别要注意的是形容词最高级前面必须要加定冠词the.如：

tall(原形)----taller(比较级)------the tallest(最高级)

long(原形)-----longer(比较级)-----the longest（最高级）

注意：比较的两者应该是互相对应的可比较的东西。如：

典型错误： My hair is longer than you .(我的头发比你长) 比较的两者是我的头发、你（整个人），那么比较的对象就没有可比性。

应该改为：My hair is longer than yours或My hair is longer than your hair.

三．形容词原级、比较级、最高级的基本用法

1.原级用法：如果比较的两者程度是一样的，我们会用as...as这个词组。 它的基本结构为：

A+be+as+形容词原形+as+B 表示A和B的程度是一样的 如：

She is as tall as you.她和你一样高。

2.比较级的用法：

1）A+be+形容词比较级+than+B A比B怎么样。。。。

She is taller than you.她比你高。

2）比较级+and+比较级（越来越。。。。。）

Our school is becoming bigger and bigger.我们的学校变得越来越大。 注：若形容词为多音节的形容词应改为：more and more+形容词原形

如：Our school is becoming more and more beautiful.我们的学校变得越来越漂亮。

3）the+比较级，the+比较级 （越怎么样，就越怎么样）如： 如：The more,the better.越多越好。

3.最高级的用法： 标志词：of/in

结构：A+be+形容词最高级+of/in+比较范围 （A在。。。中为最。。。。）

He is the tallest in his class.他在他的班上是最高的。

注：可以用来修饰形容比较的词有：even/much/little/far/still

He is much taller than me.他比我高很多。
