在定語從句中，當(dāng)先行詞是表示時(shí)間、地點(diǎn)或原因的名詞時(shí)，就要分別用關(guān)系副詞when,where,why來引導(dǎo)，在從句作狀語。關(guān)系副詞when,where,why的含義相當(dāng)于“幾次+which"結(jié)構(gòu)，因此常?？梢院汀苯樵~+which"結(jié)構(gòu)交替使用。
1.I remembered the day when(on which)I first came to the school.
2.Beijing is the place where(in which)I was born.
3.Is this the reason why (for which) he refused to help you?
關(guān)系代詞VS關(guān)系副詞
選擇關(guān)系代詞，還是關(guān)系副詞首先要判斷先行詞在定語從句中充當(dāng)?shù)某煞?關(guān)系代詞一般充當(dāng)主語、賓語（whose充當(dāng)定語）；而關(guān)系副詞一般充當(dāng)狀語。
1.This is the factory where I stayed last year.
2.This is the factory which I visited last year.
3.I'll never forget the days when I worked with you in the city.
4.I'll never forget the days that I spent with you in the city.
Choose the best answer
1.Is this the museum (B) you visited a few days ago?
A where   B that   C on which   D the one
2.Is this museum (D) you visited a few days ago?
A where  B that  C on which   D the one
Fill in the blanks
1.The reason (that/which)he gave us is enough.
2.The reason (why)he was late is unknown.
3.We must learn to act in ways(that/which)do not harm other living things.
4.I don't like the way(that/in which)he talks.
5.This is the way (that/which)he thought of to solve the problem.
介詞+關(guān)系代詞
1.根據(jù)介詞和定語從句中謂語動(dòng)詞的習(xí)慣搭配。
Who is the man with whom you just shook hands?
In the dark street there wasn't a single person (D)she could turn for help.
A that   B who   C from whom   D to whom
解析：答案為D。介詞to和定語從句中的turn構(gòu)成固定搭配turn to sb for help,意為“向某人求助”
2.根據(jù)定語從句意思的需要，此時(shí)不但要注意其前的搭配也要注意其后的搭配。
He had a bad cold,because of which he didn't attend the meeting.
In the office I never seem to have time until after 5:30pm (D)many people have got home.
A whose time   B that   C on which   D by which
介詞：答案為D。根據(jù)句意“到下午5:30時(shí)，許多人已經(jīng)到家了”，且定語從句又用了完成時(shí)，故應(yīng)用介詞by.
注意
1）介詞后面的關(guān)系詞不能省略。
2）that 前不能有介詞。
3）某些在從句中充當(dāng)時(shí)間，地點(diǎn)或原因狀語的“介詞+關(guān)系詞”結(jié)構(gòu)可以同關(guān)系副詞when,where和why互換。
This is the house in which I lived two years ago.
This is the house where I lived two years ago.
4.whose 可轉(zhuǎn)換為“of+關(guān)系代詞”型
They live in a house,whose door opens to the south.
They lived in a house,of which the door opens to the south.
They lived in a house,the door of which open to the south.
Fill in the blanks with proper prepositions
1.The sun gives us heat and light,(without) which we can't live.
2.The student (about)whom we were talking is the best student in our class.
3.I'll never forget the day(on) which she said good-bye to me.
4.Who can give me the reason (for) which he hasn't turned up yet?
5.In the dark street,there wasn't a single person (to whom)she could turn for help.
6.He paid the boy $10 for washing the windows,(most of which)hadn't been cleaned for at least a year.
The Non-Restrictive Attributive Clause
非限制性定語從句
1.限制性定語從句和非限制性定語從句：
限制性定語從句：所謂限制性定語從句就是先行詞在意義上不可缺少的定語，如果去掉，主句就會(huì)失去意義或意義不完整。這種從句和先行詞的關(guān)系十分密切，寫時(shí)不用逗號(hào)和主句分開。
I was the only person in my office who was invited.
我是我們辦公室唯一被邀請的人。
（如果把從句去掉，整個(gè)句子的含義就變了）
非限制性定語從句：非限制性定語從句和主句的關(guān)系并不十分密切，只是對先行詞做些附加說明，如果去掉，主句的意思仍然清楚。這種從句和主句之間往往有逗號(hào)隔開。在講話時(shí)語調(diào)上須停頓，一般不用that引導(dǎo)。
His dog,which was then very old,became ill and died.
他的狗當(dāng)時(shí)很老了，生病后就死了。
（去掉從句，主句的意義仍然完整；他的狗生病死了）
2)Yesterday I met Li Lei,who seemed to be very busy.
昨天我碰到李雷了，他好像很忙。
（去掉從句，意義仍然完整，昨天我碰上李雷的）
2.非限制性定語從句中的一些問題
a.非限制性定語從句中，指物時(shí)，用which而不用that.
1)Football,which is a very interesting game,is played all over the wrold.
2)All the books there,which have beautiful pictures in them,were written by him.
b.指人時(shí)主格用who,賓格whom，物主格whose(也可指物）
1）Miss Howe,whom you met in the library,is our new teacher.
2)The Arabs,who are famous for their horses and camels,use these animals for work and in sports.
3)Li Ming,whose mother has been ill for two days,is absent from school today.
c.另外關(guān)系副詞when(指時(shí)間），where（指地點(diǎn)）也可以引導(dǎo)非限制性定語從句（注意關(guān)系副詞why不能引導(dǎo)非限制性定語從句）；why不引導(dǎo)定語從句。
1)He lives in the city,where there is a high tower.
2)The People's Republic of China was founded in 1949,when he was born.
d.介詞加關(guān)系代詞也可以引導(dǎo)非限定性定語從句
1)Wu Dong,with whom I went to see the film,enjoyed it very much.
2)Her bag,in which she put all her books,has not been found.
3)The story about the Long March,of which this is an example,are well written.
3.as,which非限定性定語從句
由as,which引導(dǎo)的非限定性定語從句，as和which可代整個(gè)主句，相當(dāng)于and this或and that.as一般放在句首，which 在句中。
As we know,smoking is harmful to one's health.
The sun heats the earth,which is very important to us.
as引導(dǎo)的限制性定語從句
as在定語從句中作主語、賓語、或表語。as常用于the same...as,such...as,as...as和so...as結(jié)構(gòu)中。as引導(dǎo)的定語從句常采用省略形式。
I have never seen such a lazy man as you (are).
我從來沒有見過像你這樣懶的人。（作表語）
