天天好学网副词的用法
副词（Adverb 简称adv.）是指在句子中表示行为或状态特征的词，用以修饰动词、形容词、其他副词或全句，表示时间、地点、程度、方式等概念。副词可分为：时间副词、频率副词、地点副词、方式副词、程度副词、疑问副词、连接副词、关系副词、表顺序的副词以及表完成的副词。下面是整理的副词的用法，参考一下。
一、副词的基本特征：用来表示行为或状态特征;大多结构为形容词后+ly;它亦有比较级和最高级.
1、副词是表示行为状态特征的词,在句子中属于修饰性词类.
2、大多副词是形容词后+LY构成的.
quickly ; slowly; bravely
3、以Y结尾的形容词把‘y’变‘i’在加‘ly’.
happy--happily angry--angrily
4、有些副词没有特殊的字尾.
now; often; here; quite; never; very
5、有些副词于形容词相同.
late early high long
6、只有可以分成比较等级的副词才可以有比较级和最高级形式,例如：fast,easily,early等.像only,realy,there,here则不可能有比较等级,因为它们是不可分级的.
二、 副词的种类：
1、时间副词：today,yesterday,before,now,then等.

2、地点副词：here,there,inside,outside,downstairs,everywhere等.

1—5种副词一般是用来修饰动词、形容词或其它副词,说明动词的时间、地点、方式、程度或频率等,又或以把它们统称为修饰性副词.

7、连接副词(用来引导一个名词从句)：how,where ,when,why,whether.

三、副词的作用：
副词主要可以用来修饰动词、形容词、其它副词,有时修饰整个句子.有些副词在句子中还可以做形容词、关系代词或宾主补足语.
I konw him quite well.(作副词)
He is out at the moment .(形容词)
Look at the trees there .(关系代词)

四、副词的位置：
1、副词修饰动词放在动词之后,若是及物动词则放在宾语之后.
句型：主语+动词+宾语+副词

2、频率副词通常放在动词之前,但如果句子里有情态动词、助动词或be动词,则放在这类动词之后.

定语从句省略关系副词
1）when, where, why
关系副词when, where, why的`含义相当于"介词+ which"结构，因此常常和"介词+ which"结构交替使用，例如：
there are occasions when (on which) one must yield.任何人都有不得不屈服的时候。
beijing is the place where (in which) i was born.北京是我的出生地。
is this the reason why (for which) he refused our offer?这就是他拒绝我们帮助他的理由吗？
2）that代替关系副词
that可以用于表示时间、地点、方式、理由的名词后取代when, where, why和"介词+ which"引导的定语从句，在口语中that常被省略，例如：
his father died the year (that / when / in which) he was born.他父亲在他出生那年逝世了。
he is unlikely to find the place (that / where / in which) he lived forty years ago. 他不大可能找到他四十年前居住过的地方。
定语从句的知识点
1. where指地点，在定语从句中做地点状语用来表示地点的定语从句。
(1) Shanghai is the city where I was born.
(2) The house where I lived ten y ears ago has been pulled down.
2. when引导定语从句表示时间。在定语从句中做时间状语也可做连接词用
(1) I still remember the day when I first came to the school.
(2) The time when we got together finally came.
[注]表示时间"time"一词的定语从句只用when引导，有时不用任何关系代词，当然也不用that引导。
By the time you arrived in London, we had stayed there for two weeks.
到你到达伦敦的时候，我们在那里已经待了两个星期。
I still remember the first time I met her. 我仍然记得我第一次见到她。
Each time he goes to business trip, he brings a lot of living necessities, such as towels, soap, toothbrush etc。
每一次他去出差，他带来了生活必需品，如毛巾，肥皂，牙刷等，很多。
3. why指原因 在定语从句中做原因状语
(1) Please tell me the reason why you missed the plane.
(2) I don't know the reason why he looks unhappy today.
注意：关系副词引导的从句可以由"介词+关系代词"引导的从句替换
(1) The reason why/ for which he refused the invitation is not clear,
(2) From the year when/in which he was going to school he began to know what he wanted when he grew up.
注：1）介词后面的关系代词不能省略。
2）that前不能有介词。
3） 某些在从句中充当时间，地点或原因状语的"介词+关系词"结构可以同关系副词when ,where和why 互换。
This is the house in which I lived two years ago.
This is the house where I lived two years ago.
Do you remember the day on which you joined our club?
Do you remember the day when you joined our club?
This is the reason why he came late.
This is the reason for which he came late.
