普通代词和关系代词的区别
I have a sister. She works in Shanghai.
I have a sister who/that works in Shanghai.
普通的人称代词，
指代前文的sister.
关系代词，指代前文的sister又起到连词的作用，连接了两个句子。

when 指时间，在从句中作时间状语，它的先行词为time, day, morning, night, week, year, moment, period, age等，亦可用“介词+which”替代。例：
I remembered the day when I arrived in this big city.
我记得我到达这个大城市的那一天。。
二、关系副词的用法---when
when 作时间状语，意为 on the day, 可用on which代替
where指地点，在从句中作地点状语。它的先行词除了可以是表示具体地点的名词（如place, spot, street, house, room, city, town等）外，还可以是表示抽象地点的名词（如job, life, situation, point, case, stage, activity等），可用“介词+ which”替代。例：
I went back to the place where I was born and grew up.
我回到了我出生、成长的地方。
二、关系副词的用法---where
where 作地点状语，意为in the place,可用in which替换
why 指原因或理由，它的先行词只有reason，
在定语从句中作原因状语，亦可用“介词for+ which”替代。例：
Please give me the reason why you were late this time.
请给我这次你迟到的理由。
二、关系副词的用法---why

Sum up:关系副词的指代关系
关系副词 先行词 关系副词在从句中所作的成分 是否可省略
when(=at/on/in/during which) 表时间 时间状语 否

why(=for which) 表原因 原因状语 否
特别提醒：how不能引导定语从句。
Today is March, 12th , on which people get together to plant trees !
This is the house , in which I lived two years ago.
That is the reason, for which she asked for a leave.
on which,在从句中作时间状语，
可直接用关系副词when
when
in which,在从句中作地点状语，
可直接用关系副词where
where
for which,在从句中作原因状语，
可直接用关系副词why
why
关系代词和关系副词的区别
关系代词
在从句中作主语、宾语、定语、表语
关系副词
在从句中作状语
并非先行词是表示时间、地点和原因的名词时都用when,
where, why。在选择关系词时，最重要的是分析定语从句
所缺的成分。若从句缺主语、宾语、定语、表语，就用关
系代词；若从句缺状语，就用关系副词。
The terrible accident happened on the day _________ my father left for America, a day _________ we’ll never forget.
解析：句中有两个先行词，都是day, 第一空所填词在从句中作时间状语，所以填when；第二空所填词在从句中作宾语，所以用that/which,也可省略不填。
典例剖析
【特别提醒】遇到类似的题目，考生应特别注意从句中动词是及物动词还是不及物动词。及物动词后应接宾语；不及物动词后如有介词，可加宾语，如无介词，则应用关系副词。
when
which/
that
试比较：
I will never forget the days_______________ I spent
with my grandmother in the countryside.
I will never forget the days __________ I spent my summer holiday in the countryside.
when
spend是vt.从句缺宾语，先行词放回从句作宾语，应用关系代词which/that.
虽然横线前后都是完整的句子，但明显有内在关系，the days放回后面的句子做时间状语，所以找关系副词when, 既能指代前面先行词在从句中作状语，又能起到连词的作用。
which/that
试比较：
Put the book back to the desk ________ others can easily find it.
Put the book back to the desk _________ John moved in.
where
which/
that
先行词在从句中作地点状语
先行词在从句中作moved的宾语
再比较：
Nobody believed the reason ___________ he put forward in the meeting.
The reason ______ he didn't want to attend the meeting is still unknown.
which/
that
先行词the reason 在从句中作put forward 的宾语
why
先行词the reason 在从句中作状语
确定关系词的步骤
1.先找先行词;
2.看先行词指的是人还是物;
3.看关系词在从句中充当的句子成分。
（作什么成分？主语、宾语、定语或状语）
定语从句考点：关系词的选用

三、“介词+关系代词”引导的定语从句
1. 用法
关系代词在定语从句中作介词宾语时, 从句常常由 “介词+关系代词”引导
2. 结构
先行词是人用 “介词+whom/whose”
先行词是物用 “介词+which/whose”
e.g. The school in which he once studied is very famous.
The girl about whom we are talking is a doctor.
我们正在谈论的那个女孩是个医生。
他曾经上学的学校非常著名。
在这个结构中，关系代词不可选that或who
介词+关系代词: 介词的选择
1. 根据先行词来确定介词
He will never forget the day on which he failed in the exam.
on the day在那天
1949 was the year in which the P.R.C. was founded.
found in this year
2.根据从句的谓语动词或形容词固定搭配确定
He is the person from whom I learn a lot.
learn from sb.向某人学习
The West Lake, for which Hangzhou is famous, is a beautiful place.
be famous for因…..而闻名
3. 根据整个句子的句意确定介词
Air, without which man can’t live, is really important.
… without air…
We had supper at six o'clock, after which I went to see my uncle.
after 表示“在这之后”

1. Copper is one of the metals we are most familiar.
A.to which B.with which
C.where D.which
解析：sb be familiar with sth= sth be familiar to sb
答案: B
典例剖析
The farm we worked ten years ago isn’t what it used to be.
He is the man you can turn for help.
This is the tree we used to play games.
on which
to whom
under which
on the farm 在农场
turn to sb. for help 向某人求助
under the tree 在树下
This is the car ____which I paid 100$.
This is the car ____which I spent 100$.
This is the car ____which I go to work every day.
This is the car ______ which I can’t go to work.
for
on
in
without
特别提醒
1.有些含有介词的动词短语一般不拆开, 介词仍放在后面,如: look for, look after, look forward to, take care of等
e.g. The baby whom the nurse is looking after is very healthy.
2. 在“介词+which/whom”引导的非限制性定语从句中，介词不能移到从句的后面
注意：
There are many occasions ________ which you are left in a helpless situation, ________ which you can depend on no one other than yourself.
解析：句意：很多时候你处于无助的境地，在这种情况下，除了自己，你谁也倚靠不了。第一空，此处用on which引导定语从句修饰occasions，on many occasions表示很多时候；
第二空，此处用in which引导定语从句修饰situation，situation表示抽象地点，其前常用介词in。
答案: on; in
典例剖析
特别提醒
3. 当介词放在关系代词之前时，关系代词不能省略。
4. 在限制性定语从句中，介词位于从句末尾，关系代词that/which/who/whom作介词的宾语时可省略。
Is this the pen with which you wrote the letter
= Is this the pen (that/which) you wrote your letter with
这就是你写信用的那支钢笔吗？
注意：
1. “介词+关系代词”前还可有不定代词(some, any, none, all, both, neither, many, most, each等), 数词, 百分数, 或形容词最高级修饰。
She has two sons, both of whom are doctors.
2. 介词短语+关系代词（which,whom,whose）
They arrived at a farmhouse, in front of which sat an old man.
深化拓展
3. 单个介词+关系代词（which,whose）+名词
e.g. Our English teacher, with whose help we have made great progress in English, has completed thirty years of teaching.
4. whose引导的定语从句, 关系代词whose可替换为 “the+名词 + of + which/whom”或 “of which/whom + the + 名词”
e.g.
I live in the house whose roof is red.
= the roof of which is red.
= of which the roof is red.

定语从句的种类
限制性定语从句和非限制性定语从句
限制性定语从句和非限制性定语从句：
例如：My sister, who is twenty, works in a bank.
我的姐姐，30岁，在银行工作。（从句可省，意思仍完整）
He tore up my photo, which made me very angry.
他撕掉了我的照片，这让我很生气。
（先行词除了是名词、代词之外，还可以是整个句子）
例如：This is the house where the artist was born.
这就是那位艺术家出生的房子。（从句不可省，否则意思不完整）
限制性定语从句是先行词在意义上不可缺少的定语，如果去掉，主句的意思就不完整或失去意义。这种从句和主句关系十分密切， 写时不用逗号分开。如：
非限制性定语从句和主句关系不很密切，只是对先行词作些附加说明，
如果去掉，主句的意思仍然清楚。这种从句， 写时往往逗号分开。

限制性和非限制性定语从句的区别
试比较：
有时，同一个定语从句，是限制性的还是非限制性的，在意义上可能有一定的差别。如：
Mr Zhang has a son who likes to play football. (限制性定语从句)
张先生有一个喜欢踢足球的儿子。（可能还有别的孩子，不喜欢踢球）
Mr Zhang has a son, who likes to play football. (非限制性定语从句)
张先生有一个儿子，喜欢踢球。 （只有这么一个儿子）

非限制性定语从句中的关系词
在非限定性定语从句中，不能用关系副词why和关系代词that。要用for which代替why.
I had told them the reason, for which I didn’t attend the meeting.
我已经把理由告诉了他们，为此我没有去开会。
单句语法填空
1. This city, ______ lies in the northest and ______ I spent my childhood, has been one of the country's busiest ports since the 1950s.
2. They were well trained by their masters _______ had great experience with caring for these animals.
3. She and her family bicycle to work, _______ helps them keep fit.
which
where
who/that
which
总结：无提示词，且空前是名词，空后为缺少主语的从句，由此可判断填从句引导词
总结：定语从句有逗号，无that.
总结：在非限制性定语从句中，先行词为物时，不可用that. 第二空后的定语从句主谓宾结构完整，缺状语，故填where
定语从句的关系词只有9个：
先行词 主语 宾语 表语 定语 状语

as引导的定语从句
1. 限制性定语从句
在从句中作主语、宾语、表语或状语，构成the same...as, such...as, so...as等结构。如：
Here are such questions as are often asked by the college students.
这是些大学生们常常问的那类问题。（as作主语）
This is the same computer as I have bought.
这台计算机和我买的那台一样。（as作宾语）
I have never seen such kind of girl as she is.
我从未见过像她这样的女孩。（as作表语）
Here is so easy a question/such an easy question as everyone can answer.这个问题很容易，谁都能答得上来。（as作结果状语）
【比较1】
I live in the same house that he used to live in. （同一间房子）
I'm wearing the same shirt as you wore yesterday.
（相像的，不是同一件T恤）
【比较2】
Here is so big a stone as no one can lift. （as作宾语，引导定语从句）
这里有一块大石头，谁也抬不动。
Here is so big a stone that no one can lift it.（that引导结果状语从句，从句不缺成分）
这块石头太大，以至于没人能把它举起来。
难点分析
2. 非限制性定语从句
as引导非限制性定语从句时，代替整个主句，对其进行说明。在从句中可作主语、表语或宾语，且引出的从句位置比较灵活，可位于句首或句末，也可插入主句中间。通常均由逗号将其与主句隔开，意为“正如...”, “就像...”。常用于以下结构：as we all know, as is known to all,
as is it, as is said above, as already mentioned above, as is usual,
as is often the case, as is reported in the newspaper, as we had expected等。如：
As we know, China is famous for its Four Great Inventions.
=China，as we know, is famous for its Four Great Inventions.
=China is famous for its Four Great Inventions, as we know.
众所周知，中国因其四大发明而闻名。（as在从句中作宾语）
=As is known to all, China is famous for its Four Great Inventions.
（as在从句中作主语）=It’s known to all that……
易混关系代词的辨析：as/which
1. 位置不同
as引导的非限制性定语从句的位置比较灵活，而which引导的非限制性定语从句一般放在先行词的后面。
2. 含义及其后行为动词的语态不同
as引导的非限制性定语从句通常意为“正如”，而which通常表示“这一点”。
关系代词在从句中作主语时，as后常接行为动词的被动语态，如as is known,
as is reported等；若从句为主动语态，一般用which。
eg: She is absent again, as is expected. 正如所预料的那样，她又缺席了。
Tom has made great progress, which makes me very happy.
汤姆取得了很大的进步，这使我很高兴。
3. 在限制性定语从句中，当先行词被the same, such修饰时，其后的定语从句常用as来引导而不是which.
3. ______ is known to all, he is the best student.
4. Jim passed the driving test, _____ surprised everybody in the office.
As
which
难点一：as的用法
as\that\which
1. It is such a big stone _____ nobody can lift.
2. It is such a big stone _____ nobody can lift it.
as
that
归纳：as引导限制性定语从句，形成such/so…as , the same …as结构时，as在定语从句中应充主语、宾语或表语。而so/such...that引导的是结果状语从句，其后接完整的句子。
as 与which引导非限制性定语从句都能指代整句内容，但定语从句位于句首时，只能用 as, 意为“正如、恰如”。而which一般位于先行词后,意为“这一点，这件事”，相当于“and this/that”。
做题技巧
当主句中出现such 或so 时,看后面从句是否缺主语或宾语:
(1)缺主语或宾语,从句前用as；不缺用that
(2)当主句中出现the same时, 后面从句缺主语或宾语时与as搭配表同一类事物,与that搭配表同一个事物
They are such beautiful pictures as drew many people's attention.
They are such beautiful pictures that they drew many people's attention.
This is the same book as I read last week. (表示同类)
这和我上周读的那本书是一样的。
This is the same (=the very) book that I read last week. (表示同一)
这就是我上周读的那本书。
模拟训练 ：
1. He is such a lazy man_____ nobody wants to work with______.
A. as; him B. that; /
C. as; / D. whom; him
2. Mrs. Black took the police back to____ place ____ she witnessed the robbery.
A. the same; as B. the same; where
C. the same ; that D. as the same; as
3. [语法填空]I have never performed such a task _______ you've aked me to do.
as
【典例剖析1】She is ______ good doctor that everyone wants to see her.
A. such a B. a such C. a very D. so
【解析】修饰单数可数名词时，such a adj+n=so adj/adv a+n.
如果是复数n/不可数n，用such；但只有adj/adv时，应用so。
若遇few, little(少), many, much等词时，优先选so.
【典例剖析2】He offered _______ valuable advice that _______ people disagreed.
A. such; a few B. such; few C. so; a few D. so; few
【解析】few 意为“几乎没有”；a few意为“有一些”。such词性为adj,
要修饰n; 而so词性为adv,要修饰v,adj,adv。

易混关系代词的辨析：that/who(m)
1.当先行词指人时，只用who, 不用that的情况：
在非限制性定语从句中
eg: Li Chen is a charming man, who appeals to many fans.
2. 在“介词+关系词”引导的定语从句中, 只用whom
eg: Huang Xiaoming is the lucky man with whom Baby got married.
3. 当先行词是everyone/ all/ one(s)/those/ nobody 等不定代词时
eg: Those who want to get out of the room must work out the problem on the paper.
4. 在there be 句型中
eg: There was a person who had been secretly appointed as a spy.
5. 当指人的先行词被指物的名词修饰时
eg: There is only one student in the school who I want to see.
6. 当定语从句中有插入语时，且先行词为人
eg: Jackson is a man who I believe is honest.

考点归纳
1.先行词是way/time/reason 2. 与其他句型的区别
1. 先行词是表原因的名词reason
The reason (which/that) he told me for his being late is that he got up late. （作主语、宾语等，用which/that）
The reason why he was late is that he got up late.
（作原因状语，用why）
2. 先行词是time
time作“次数”讲时，应用that; 作“时刻”,“一段时间”讲时，若在从句中作状语，应用when(=at/in/during which)，若作主语、宾语, 则用that/which.
This is the second time (that) the president has visited the country.
There was a time when/during which there were no radios or TV sets.
1.先行词相同，关系词不同
3. 先行词是way
若关系词在从句中充当”in+which”式的方式状语，可用that代替in which，或省略；若关系词在从句中充当主语或宾语等成分，则用that或which.
①It must be the way (that/in which) you write that leads to your ugly handwriting. （关系词做方式状语，可用that代替in which,或省略）
一定是你写字的方式导致了你难看的字迹。
②The way (that/which) you came up with at the meeting yesterday is well
worth trying. (关系词做宾语，用that/which，或省略)
昨天你在会议上提出的方法很值得一试。
1.先行词相同，关系词不同
All _____ we need is to be supplied with food and clothing.
A. what B. that C. which D. whom
2. I don’t like the way____ you speak to her.
A. that B. in that C. where D. which
Exercises:
① 定语从句与并列句
并列句有and, but, so, or等并列连词或分号连接各个分句。这种情况下，不可再用引导定语从句的关系词
I have three cars, none of _________ is in good condition. (非限制性定语从句)
I have three cars, but none of __________ is in good condition. (but并列句)
② 定语从句与同位语从句
定语从句在复合句中相当于形容词，对先行词起修饰或限制作用。
同位语从句的作用相当于名词，对前面的名词进行补充说明或进一步解释，是前面
名词的具体内容。
The suggestion (that) he came up with is practical.(定语从句，做宾语, 可省)
He gave me the suggestion that we should read aloud every day.
(同位语从句，不做成分，不可省)
2.与其他句型的区别
which
them
③ 定语从句与状语从句
when,where和why引导定语从句时可以用“介词+which”的结构替换，引导状语从句时却不行。
This is the school where (=in which) I once worked. (定语从句)
Put back the book where it was. (状语从句)
定语从句的关系代词在从句中充当某种句子成分，因此去掉之后从句成分不完整；而状语从句中的连接词在从句中不做任何成分，去掉后从句的成分仍然完整。
It is such an interesting book as we all like.
(as引导定语从句，做从句的宾语)
It is such an interesting book that we all like it.
(that引导结果状语从句，不充当从句成分)
2.与其他句型的区别
