形容词的位置：

·置于被修饰词前：I often have a joyful heart

·置于被修饰词后：

1表语形容词作定语：The baby still asleep might be awake very soon

注意：有些词前后位置对调意义大相径庭，比如 what is your present address？你现在的地址是什么？ The people present at the meeting are mostly from China出席会议的人大多数来自中国

2修饰复合不定代词：修饰someone，something，anyone，anything，nothing等复合不定代词时，需要置后。I have something important to tell you

3形容词短语作定语：“形容词+介词+名词”时，放名词后面He gave me a box full of books

4并列连词连接的形容词作定语:2个意义相反的形容词中间用and或or连接作定语时，常放名词后。All the poeple on this island，young or old，are all fond of music

多个形容词修饰同一词时的排序：由和被修饰词的关系密切程度来决定，一般规律（限定词，如冠词，名词所有格，物主代词，指示代词和数词等+）观点+形状+年龄/新旧+颜色+来源+材料/种类。

There are a few big round new black French wooden tables in the room/I’ll always remember the last few unforgettable sunny days on the beach

形容词的比较等级：

·没有比较级和最高级的形容词 right，wrong，possible，impossible，east，empty，favorite，round，golden，first

·有比较级和最高级的形容词：

1规则变化的：great-greater-greatest ，nice-nicer-nicest ，big-bigger-biggest ，happy-happier-happiest ，heavy-heavier-heaviest ，difficult-more difficult-most difficult ，interesting-more interesting-most interesting ，exciting-more exciting-most exciting

2不规则变化的：good/well-better-best，bad/ill-worse-worst， little-less-least，much/many-more-most，far-farther-farthest距离，far-further-furthest距离，程度， old-elder-eldest年长

比较等级用法：

·原级比较：

My dress is as beautiful as yours我的裙子和你的一样好 / I am not as/so busy as I

Used to be我没有过去那么忙了 / we have produced as many tractors as we did last year我们生产的拖拉机和去年一样多

·比较级：

1“比较级+than”表一方超过或低于另一方 You look much younger than I do你看上去比我年轻多了

2“比较级+and+比较级”表事物本身程度的逐渐增长，意为“越来越” As spring is coming，the day is becoming longer and longer / Our country is becoming more and more beautiful

3“the+比较级(+of the two...)”表“两者中更...的那一个”.当比较双方只出现一方(没有than及后面的部分),且句中含有of the two时，比较级前要加the。 The larger of the two houses belongs to Mr.Black

4表两者程度不同也可用more than多于...，not more than不比...多，less than少于，not less than不少于，less+adj+than不如... We haven't got more than one hour left我们现在还有不到一个小时了 / He was less careful than I imagined他比我想象的粗心

5“the+比较级...，the+比较级...”表一方的程度随着另一方的程度变化而变化，意为”越...就越...” The more difficult the problem is,the more careful we should be

6“not+比较级+than”意为一方不如另一方...； “no+比较级+than”意为双方一样都不...；修饰说明数量时，前者表“最多，不比...多”，后者表带感情色彩的“仅仅”。

I’m not taller than you我不如你高 / I’m no taller than you我和你一样都不高

She is not more than seven years old她不到7岁 / She is no more than seven years old她才仅仅7岁

·最高级：3者或更多者中程度最高的比较方式

1 “the+形容词+名词+范围的短语或从句” Jack is the tallest student in his class /This is the most boring book I’ve ever read

2“one of the+形容词最高级+可数名词复数+范围”China is one of the largest countries in the world

注意用法比较：在一定区域空间内进行比较用in，在同一类事物范围进行比较用of。 China is the largest country in Asia 中国是亚洲最大的国家/ China is the largest one of all the Asian countries中国是亚洲所有国家中最大的

3 比较级表达最高级：“比较级+than any other+可数名词单数”/“比较级+than the other+可数名词复数”/“比较级+than the rest of + the+可数名词复数”都可表示最高级意义

Diao is taller than any other girl in her class

Diao is taller than the other girls in her class

Diao is taller than the rest of the girls in her class

Diao is the tallest of the girls in her class

·常见的比较级错误：

1, more不可修饰比较级，但much可以加强比较级，意为”...得多”：

He Looks more younger than I do(×) He looks much younger than I do(√）

2, 比较的对象或范围出现错误：

The weather of Beijing is colder than Shanghai(×) The weather of Beijing is colder than that of Shanghai(√)比较的对象是上海的天气，而不是上海

China is larger than any other country in Asia(√) China is larger than any country in Africa(√) China is larger than any country in Asia(×) 中国本来就是亚洲国家，应当排除在外，所以错误。

注意：than后面接代词时，要用宾格。如果than后面是一个句子，则不可使用宾格=> He works harder than me / He workd harder than I do.

·比较级和最高级的修饰语：

1，比较级的修饰语：much...得多，even更，still更，(by)far...得多，a lot很，a great deal of大大地，twice两倍，five times五倍，two fifths五分之二，a half一半，a little有点，a bit of有点...

I feel much/a great deal better today / He is five years older than me / Your handwritting is (by)far better than mine

·最高级的修饰语：(by)far/far and away最，second第二，almost几乎，nearly几乎

The Yellow River is the second longest river in China / This is (by)far the best book that I’ve ever read.

·比较结构的同义转换

1，not as/so...as和less...than的转换：

The place was not as/so crowded as it usually is yesterday = The place was less crowded than it usually is yesterday昨天，这个地方不像平常那样挤满了人

2, more...than和less...than, not as/so...as的转换

Your picture is more beautiful than his. = His picture is less beautiful than yours =His picture isn’t as/so beautiful as yours你的画比他的好看

3,最高级和more...than, no...more than的转换

·常见形容词用法比较：

1，Elder和older：

Diao is the fourth of five children，having two elder brothers and a younger sister这里elder只能作定语，不能用于than引导的比较状语从句中

Diao is seven years older than her younger sister这里older可指人也可指物，作定语/表语，能用在than引导的比较状语从句中。

2，Good和well：

都表示“好”，good常作定语/表语，well一般作表语且只表示“身体好”，另外well可作副词表“好”

Doing sports is good for us（表语）

I’m very well,thank you.（形容词，身体好）

Diao dances well and she is good dancer（well是副词作状语修饰dance，good作定语)

3, Huge，big，large和great：

The spaceship is huge(强调尺寸，体积“庞大”-比large/great还要大，容量/数量“巨大”不强调重量）

We had a big fight in the school last week(最通俗常用，强调比正常程度/范围/规模要大，常修饰人/物/数量，反义词是little/small)

The large object had a close relationship with the death of dinosaurs.(强调远超标准的“大”，可指数量/容量/体积/面积，比big正式，反义是small)

This is a great chance that many people do not have(指抽象的事物，表数量/距离/程度，修饰人指“伟大的”)

2，interested和interesting

She is interested in sports作形容词，意为“感兴趣的”，常构成西表结构be interested，主语通常是人，说明外界/某人/某事令人产生这种感觉

She is interesting 作形容词，意为“令人感兴趣的”，句中作定语/表语，说明人/事物具备让他人产生某种感受的特性。

注意：英语中大多数-ing形式和-ed形式的形容词用法都和interested/interesting类似。
