Ⅰ.形容词和副词的概念及区别

形容词修饰的是名词或代词，表示人或事物的性质、特征或状态。形容词在句子中作定语、表语或宾语补足语。

Once a rich woman invited Martin Brown，a famous singer，to her house.

These ideas may seem strange to you.

They keep their room clean.

某些表示特征的形容词(如blind，dead，old，young，rich，poor，brave，wounded等)和定冠词连用从而名词化，可泛指一类人，在句中作主语、宾语等

The aged are well taken care of in our society.

The departed was a good teacher in our department.

副词修饰的是动词、形容词、副词或全句，说明时间、地点、程度、方式等概念。副词在句子中大都作状语，也有一些副词作表语和定语。本文|由职业培训教育网独家整理。

I must be off now.

I met her on my way home.

有些形容词和副词的比较级和最高级有两种不同形式，它们在意义上也有所不同：

the former 前者

the latter 后者

◆ 在形容词和副词的比较级前，有时可以用much，a little，still，far，by far，even，no，any，a great deal等状语词来修饰，表示“更……”、“……得多”等程度意义。例如：

This is taking a little more time than we thought.

He's far behind me.

The Pacific is by far the largest ocean and covers almost half of the total ocean area.

◆ 表示甲与乙在某一方面程度相同时，用“as+形容词(副词)原级+as”的句型。

…as…as

…more…than

(1)两个as之间要用形容词或副词的原形：

He is as tall as his brother.

(2)第二个as和其后的比较对象较远，出现了第二层比较级，如：

(3)as…as之间不止一个形容词，如：

Whenever we need to be indoors, we want our surroundings to be as attractive and comfortable as possible.

It is possible to make metal as hard or as soft as is wished.

(4)在形容词后出现附带成分，如as…to do…as to do…:

(5)不同的喻体

He is as strong as a horse.

He is as mad as March hare.

He is as wet as a drowned rat.

He is as poor as church mouse.

He is as stubborn as a mule.

The twin sisters are as like as two peas.

(6)as…as用于表示倍数的句型

(1)倍数n+as…as

在as…as前加上twice, three times等可以表示倍数。

He is twice as old as she.

There are three times as many people as we expected.

This one is prettier, but it cost twice as much as the other one.

倍数n+比较级+than

比较：

◆ 可用“…times+形容词(副词)比较级形式+than…”表示“比…多(大、重、长……)……倍”。本文|由职业培训教育网独家整理。
