（1）限制性定语从句,当先行词前有as ,so ,such ,the same等修饰时，并且从句中缺主语或者宾语时,用关系词as引导限制性定语从句。

(2)非限制性定语从句，一般放在主句的前面、中间、或者主句的后面。指整个主句的内容。意为“正如……，据……，像…。
常见的结构如下:
as is said above, 正如上面所说的。
as is mentioned above,正如上面所提到的。
as is often the case (with…), (对…)这是常有的事
as is reported,就像报道的那样的。
as everybody knows,正如每个人所知道的那样。
as is known to all.众所周知。
when =介词(on/in/at/during…) +which.=介词+先行词
where =介词(on/in…) +which.=介词+先行词
why=for which=for+先行词
1、when, 在从句中作时间状语，先行词是表时间的名词.(定语从句中主语和宾语都不缺，而缺时间状语)
2、where, 在从句中作地点状语，先行词是表地点的名词。(定语从句中主语和宾语都不缺，而缺地点状语)
3、why, 在从句中作原因状语，先行词是reason. (定语从句中主语和宾语都不缺，而缺原因状语)

Tianjin is the place ___________ I was born.
Do you know the reason_______________ he was late
when
where
why/for which
关系副词
介词+关系代词
介词+关系代词引导的定语从句时，先行词是人，介词+whom；
先行词是物，介词+which 。
介词+whose(指人或物)

which
whom
关系代词前介词的确定:
（1）依据定语从句中动词的某种习惯搭配来确定
（2）依据与先行词搭配的意义而定
（3）依据所表达的句意来确定。
whose
关系词，引定从，用法各不同。
that作主、宾，指人指物它都用。
Which用来指物用，主语、宾语它也能。
Who、whom指人用，作主、宾，要分清
Whose一词它真行，指人指物都作定。
as用作主或宾，修饰全句或部分，
常和as,such,so,the same混合用。
时间状语when来用,
地点状语where行，
原因状语why选中。

易错点1. which和that
She heard a terrible noise, ______ brought her heart into her mouth.
What is that ______ flashed in the sky just now
The papers ______Mr. Li was searching were hidden by students.
which
which
which
先行词是物，用which不用that的情况 ：
1.在非限制性定语从句中。
2.先行词本身就是that时。
3.关系代词前有介词时。
He talked about the teachers and schools that he had visited.
You are the first person that I want to see.
This is the very pen that I am looking for.
Is there anything that you want in the shop
Who is the girl that is singing in the room
China is not the country that it was.
先行词既有人又有物，只能用that。
指物的先行词前有序数词或形容词最高级时，只能用that。
指物的先行词被the only, the next, the last, the very, any, little, no,all, every, some,no, much ,the right等修饰时，只能用that。
先行词是all, none, something, anything, nothing等不定代词指物时；
主句是以who/which开头的特殊疑问句时。
先行词是表语，或关系代词本身充当定语从句的表语。用that引导定语从句。
易错点2. 先行词是表示时间、地点或原因的词，关系词一定要用when, where或why？
This is the place __________ I visited years ago.
This is the place __________ I lived years ago.
I will never forget the days ________ I stayed with you.
I will never forget the days ________ I spent with you.
This is the reason __________ he gave me.
This is the reason __________ he was late.
要判断从句中缺什么成分
that/which
where
when
that/which
that/which
why
This is the factory _________ we visited yesterday.
He got into a situation _______ it is hard to decide what is right and wrong.
Today, we'll discuss some cases ________ beginners of English fail to use the language properly.
Is this the reason _________he explained at the meeting for his carelessness in his work.
It put me in a position ________ I can't afford to take the job.
that/which
where
where
that/which
where
先行词是一些表示抽象的模糊的地点名词（situation, activity, scene,degree,point,case,stage,position,degree,system,condition,process,culture,life...）时，如，如果从句中缺状语，可接where引导的定语从句；如果从句中缺主语或者宾语，则用that或者which引导定语从句。
I am not one who ____(be) afraid of difficulty.
Anyone who ______(have) questions to ask ,please come to my office.
Don’t choose me who ___(be) not tall.
She is one of the few persons who ______（know） Spanish.
She is the one of the few persons who ______(know) Spanish.
is
has
am
know
knows
关系代词在定语从句中充当主语时，定语从句中的谓语动词在人称和数方面应该与前面的先行词保持一致。
在“one of the+复数名词+定语从句”结构中，关系代词在定语从句中充当主语时，从句谓语动词用复数形式。但若one of之前有the only, only, the, this等限定词时，从句谓语动词用单数形式。“The very/right +复数名词”作先行词，从句谓语动词用单数形式。
易错点3. 定语从句中的主谓一致
