第一篇：高中英語語法教學設計 定語從句
高中英語語法教學設計：定語從句講解與練習
定語從句在句中做定語，修飾一個名詞或代詞，被修飾的名詞詞組或代詞即先行詞。定語從句通常
出現在先行詞之后，由關系詞（關系代詞或關系副詞）引出。關系代詞有：who, whom, whose, that, which等。關系副詞有：when, where, why等。
18.1 關系代詞引導的定語從句
關系代詞所代替的先行詞是人或物的名詞或代詞，并在句中充當主語、賓語、定語等成分。關系代詞在定語從句中作主語時，從句謂語動詞的人稱和數要和先行詞保持一致。1）who, whom, that
這些詞代替的先行詞是人的名詞或代詞，在從句中作主語和賓語。例如：
Is he the man who/that wants to see you? 他就是你想見的人嗎？（who/that在從句中作主語）
He is the man whom/ that I saw yesterday.他就是我昨天見的那個人。（whom/that在從句中作賓語）2）whose 用來指人或物，（只用作定語, 若指物，它還可以同of which互換）。例如：
They rushed over to help the man whose car had broken down.那人車壞了，大家都跑過去幫忙。
Please pass me the book whose（of which）cover is green.請遞給我那本綠皮的書。3）which, that所代替的先行詞是事物的名詞或代詞，在從句中可作主語、賓語等。例如：
A prosperity which / that had never been seen before appears in the countryside.農村出現了前所未有的繁榮。（which / that在句中作賓語）
The package（which / that）you are carrying is about to come unwrapped.你拿的包快散了。（which / that在句中作賓語）
18.2 關系副詞引導的定語從句
關系副詞可代替的先行詞是時間、地點或理由的名詞，在從句中作狀語。1）關系副詞when, where, why的含義相當于“介詞+ which”結構，因此常常和“介詞+ which”結構交替使用。例如：
There are occasions when（on which）one must yield.任何人都有不得不屈服的時候。
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? 這就是他拒絕我們幫助他的理由嗎？
2）that代替關系副詞，可以用于表示時間、地點、方式、理由的名詞后取代when, where, why和“介+which”引導的定語從句，在口語中that常被省略。例如：
His father died the year（that / when / in which）he was born.他父親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過的地方。
18.3 判斷關系代詞與關系副詞
方法一：用關系代詞，還是關系副詞完全取決于從句中的謂語動詞。及物動詞后面無賓語，就必須要求用關系代詞；而不及物動詞則要求用關系副詞。例如：
This is the mountain village where I stayed last year.這是我去年呆過的山村。
I'll never forget the days when I worked together with you.我永遠不會忘記與你共事的日子。
判斷改錯：
（錯）This is the mountain village where I visited last year.（錯）I will never forget the days when I spent in the countryside.（對）This is the mountain village（which）I visited last year.（對）I'll never forget the days（which）I spent in the countryside.習慣上總把表地點或時間的名詞與關系副詞 where, when聯系在一起。此兩題錯在關系詞的誤用上。
方法二：準確判斷先行詞在定語從句中的成分（主、謂、賓、定、狀），也能正確選擇出關系代詞/關系副詞。例1.Is this museum ___ you visited a few days age?
A.where B.that C.on which D.the one
例2.Is this the museum ____ the exhibition was held.A.where B.that C.on which D.the one 答案：例1 D，例2 A
例1變為肯定句： This museum is ___ you visited a few days ago.例2變為肯定句： This is the museum ___ the exhibition was held.在句1中，所缺部分為賓語，而where, that, on which都不能起到賓語的作用，只有the one既做了主句的表語，又可做從句的賓語，可以省略關系代詞，所以應選D。
而句2中, 主、謂、賓俱全，從句部分為句子的狀語表地點，既可用副詞where，又因 in the museum詞組，可用介詞in + which 引導地點狀語。而此題中，介詞on 用的不對，所以選A。
關系詞的選擇依據在從句中所做的成分，先行詞在從句中做主、定、賓語時，選擇關系代詞（who, whom, that, which, whose）；先行詞在從句中做狀語時，應選擇關系副詞（where 地點狀語，when 時間狀語，why 原因狀語）。
18.4 限制性和非限制性定語從句
1）定語從句有限制性和非限制性兩種。限制性定語從句是先行詞不可缺少的部分，去掉它主句意思往往不明確；非限制性定語從句是先行詞的附加說明，去掉了也不會影響主句的意思，它與主句之間通常用逗號分開。例如：
This is the house which we bought last month.這是我們上個月買的那幢房子。（限制性）
The house, which we bought last month, is very nice.這幢房子很漂亮，是我們上個月買的。（非限制性）
2）當先行詞是專有名詞或物主代詞和指示代詞所修飾時，其后的定語從句通常是非限制性的。例如：
Charles Smith, who was my former teacher, retired last year.查理?史密斯去年退休了，他曾經是我的老師。
My house, which I bought last year, has got a lovely garden.我去年買的的那幢房子帶著個漂亮的花園。
This novel, which I have read three times, is very touching.這本小說很動人，我已經讀了三遍。3）非限制性定語從句還能將整個主句作為先行詞, 對其進行修飾, 這時從句謂語動詞要用第三人稱單數。例如：
He seems not to have grasped what I meant, which greatly upsets me.他似乎沒抓住我的意思，這使我心煩。
Liquid water changes to vapor, which is called evaporation.液態水變為蒸汽，這就叫做蒸發。說明：關系代詞that和關系副詞why不能引導非限制性定語從句。
18.5 介詞+關系詞
1）介詞后面的關系詞不能省略。2）that前不能有介詞。
3）某些在從句中充當時間，地點或原因狀語的“介詞+關系詞”結構可以同關系副詞when 和where 互換。例如：
This is the house in which I lived two years ago.這是我兩年前住過的房子。
This is the house where I lived two years ago.Do you remember the day on which you joined our club? 還記得你加入我們俱樂部的那一天嗎？
Do you remember the day when you joined our club? 18.6 as, which 非限定性定語從句
由as, which 引導的非限定性定語從句，as和which可代整個主句，相當于and this或and that。As一般放在句首，which在句中。例如：
As we know, smoking is harmful to one's health.如我們所知，吸煙有害健康。
The sun heats the earth, which is very important to us.太陽使地球暖起來，這對我們人類很重要。典型例題
1）Alice received an invitation from her boss, ___came as a surprise.A.it B.that C.which D.he
答案C.此為非限定性從句，不能用 that修飾，而用which.，it 和he 都使后句成為句子，兩個獨立的句子不能單以逗號連接。況且選he句意不通。
2）The weather turned out to be very good, ___ was more than we could expect.A.what B.which C.that D.it
答案B。which可代替句子，用于非限定性定語從句，而what不可。That 不能用于非限定性定語從句，it不為連詞，使由逗號連接的兩個句子并在一起在英語語法上行不通。
3）It rained hard yesterday, ____ prevented me from going to the park..A.that B.which C.as D.it 答案B.as 和which在引導非限制性定語從句時，這兩個關系代詞都指主句所表達的整個意思，且在定語從句中都可以作主語和賓語。但不同之處主要有兩點：
（1）as 引導的定語從句可置于句首，而which不可。（2）as 代表前面的整個主句并在從句中作主語時，從句中的謂語必須是系動詞；若為行為動詞，則從句中的關系代詞只能用which.。在本題中，prevent由于是行為動詞，所以正確選項應為B。
as 的用法
例1.the same…as；such…as 中的as 是一種固定結構, 和……一樣……。例如：
I have got into the same trouble as he（has）.我碰到了跟他一樣的麻煩。例2.as可引導非限制性從句，常帶有'正如'。例如：
As we know, smoking is harmful to one's health.如我們所知，吸煙有害健康。
As is known, smoking is harmful to one's health.As是關系代詞。例1中的as作know的賓語；例2中，它充當從句的主語，謂語動詞know要用被動式。
18.7 先行詞和關系詞二合一
1）Whoever spits in public will be punished here.（Whoever 可以用 anyone who 代替）
2）The parents will use what they have to send their son to technical school.（what 可以用all that代替）
18.8 what/whatever;that/what;who/whoever
1）what = the thing which；whatever = anything。例如：
What you want has been sent here.你要的動詞都送來了。
Whatever you want makes no difference to me.不管你要什么，跟我沒什么關系。2）who= the person that whoever= anyone who。例如：
（錯）Who breaks the law will be punished.（錯）Whoever robbed the bank is not clear.（對）Whoever breaks the law will be punished.王子犯法，與庶民同罪。
（對）Who robbed the bank is not clear.誰搶了銀行還不清楚。3）that 和 what
當that引導定語從句時，通常用作關系代詞，而引導名詞性從句時，是個不充當任何成分的連接詞。賓語從句和表語從句中的that常可省略。What只能引導名詞性從句，用作連接代詞，作從句的具體成分，且不能省略。例如：
I think（that）you will like the stamps.我想你會喜歡這些郵票的。
What we need is more practice.我們需要的是更多的實踐。
18.9 關系代詞that 的用法 1）不用that的情況
a）引導非限定性定語從句時。例如：
（錯）The tree, that is four hundred years old, is very famous here.b）介詞后不能用。例如：
We depend on the land from which we get our food.我們依賴土地獲得食物。
We depend on the land that/which we get our food from.2）只能用that作為定語從句的關系代詞的情況
a）在there be 句型中，只用that，不用which。
b）在不定代詞，如：anything, nothing, the one, all, much, few, any, little等作先行詞時，只用that，不用which。
c）先行詞有the only, the very修飾時，只用that。
d）先行詞為序數詞、數詞、形容詞最高級時，只用that。.e）先行詞既有人，又有物時。例如：
All that is needed is a supply of oil.所需的只是供油問題。
Finally, the thief handed everything that he had stolen to the police.那賊最終把偷的全部東西交給了警察。定語從句練習:

高中英語語法總結大全之定語從句
定語從句
定語從句（Attributive Clauses）在句中做定語，修飾一個名詞或代詞，被修飾的名詞,詞組或代詞即先行詞。定語從句通常出現在先行詞之后，由關系詞（關系代詞或關系副詞）引出。
關系代詞有：who, whom, whose, that, which等。
關系副詞有：when, where, why等。
關系代詞引導的定語從句
關系代詞所代替的先行詞是人或物的名詞或代詞，并在句中充當主語、賓語、定語等成分。關系代詞在定語從句中作主語時，從句謂語動詞的人稱和數要和先行詞保持一致。
1）who, whom, that
這些詞代替的先行詞是人的名詞或代詞，在從句中所起作用如下：
Is he the man who/that wants to see you?
他就是你想見的人嗎？（who/that在從句中作主語）
He is the man whom/ that I saw yesterday.他就是我昨天見的那個人。（whom/that在從句中作賓語）
2)Whose 用來指人或物，(只用作定語, 若指物，它還可以同of which互換）, 例如： They rushed over to help the man whose car had broken down.那人車壞了，大家都跑過去幫忙。
Please pass me the book whose(of which)cover is green.請遞給我那本綠皮的書。
3）which, that
它們所代替的先行詞是事物的名詞或代詞，在從句中可作主語、賓語等，例如：
A prosperity which / that had never been seen before appears in the countryside.農村出現了前所未有的繁榮。（which / that在句中作賓語）
The package(which / that)you are carrying is about to come unwrapped.你拿的包快散了。(which / that在句中作賓語）
關系副詞引導的定語從句
關系副詞可代替的先行詞是時間、地點或理由的名詞，在從句中作狀語。
1）when, where, why
關系副詞when, where, why的含義相當于“介詞+ which”結構，因此常常和“介詞+ which”結構交替使用，例如：
There are occasions when(on which)one must yield.任何人都有不得不屈服的時候。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?這就是他拒絕我們幫助他的理由嗎？
2）that代替關系副詞
that可以用于表示時間、地點、方式、理由的名詞后取代when, where, why和“介詞+ which”引導的定語從句，在口語中that常被省略，例如：
His father died the year(that / when / in which)he was born.他父親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過的地方。
判斷關系代詞與關系副詞
方法一： 用關系代詞，還是關系副詞完全取決于從句中的謂語動詞。及物動詞后面無賓語，就必須要求用關系代詞；而不及物動詞則要求用關系副詞。例如：
This is the mountain village where I stayed last year.I'll never forget the days when I worked together with you.判斷改錯（注：先顯示題，再顯示答案，橫線；用不同的顏色表示出。）
（錯）This is the mountain village where I visited last year.（錯）I will never forget the days when I spent in the countryside.（對）This is the mountain village(which)I visited last year.（對）I'll never forget the days(which)I spent in the countryside.習慣上總把表地點或時間的名詞與關系副詞 where, when聯系在一起。此兩題錯在關系詞的誤用上。
方法二： 準確判斷先行詞在定語從句中的成分(主、謂、賓、定、狀)，也能正確選擇出關系代詞/關系副詞。
例1.Is this museum ___ you visited a few days age?
A.whereB.thatC.on whichD.the one
例2.Is this the museum ____ the exhibition was held.A.whereB.thatC.on whichD.the one
答案：例1 D，例2 A
例1變為肯定句： This museum is ___ you visited a few days ago.例2變為肯定句： This is the museum ___ the exhibition was held.在句1中，所缺部分為賓語，而where, that, on which都不能起到賓語的作用，只有the one既做了主句的表語，又可做從句的賓語，可以省略關系代詞，所以應選D。
而句2中, 主、謂、賓俱全，從句部分為句子的狀語表地點，既可用副詞where，又因 in the museum詞組，可用介詞in + which 引導地點狀語。而此題中，介詞on 用的不對，所以選A。
關系詞的選擇依據在從句中所做的成分，先行詞在從句中作主、定、賓語時，選擇關系代詞(who, whom, that, which, whose)； 先行詞在從句中做狀語時，應選擇關系副詞(where 地點狀語，when 時間狀語，why 原因狀語)。
限制性和非限制性定語從句
1)定語從句有限制性和非限制性兩種。限制性定語從句是先行詞不可缺少的部分，去掉它主句意思往往不明確；非限制性定語從句是先行詞的附加說明，去掉了也不會影響主句的意思，它與主句之間通常用逗號分開，例如：
This is the house which we bought last month.這是我們上個月買的那幢房子。（限制性）The house, which we bought last month, is very nice.這幢房子很漂亮，是我們上個月買的。（非限制性）
2)當先行詞是專有名詞或物主代詞和指示代詞所修飾時，其后的定語從句通常是非限制性的，例如：
Charles Smith, who was my former teacher, retired last year.查理·史密斯去年退休了，他曾經是我的老師。
My house, which I bought last year, has got a lovely garden.我去年買的的那幢房子帶著個漂亮的花園。
This novel, which I have read three times, is very touching.這本小說很動人，我已經讀了
三遍。
3)非限制性定語從句還能將整個主句作為先行詞, 對其進行修飾, 這時從句謂語動詞要用第三人稱單數，例如：
He seems not to have grasped what I meant, which greatly upsets me.他似乎沒抓住我的意思，這使我心煩。
Liquid water changes to vapor, which is called evaporation.液態水變為蒸汽，這就叫做蒸發。
說明：關系代詞that和關系副詞why不能引導非限制性定語從句。
介詞+關系詞
1）介詞后面的關系詞不能省略。
2）that前不能有介詞。
3）某些在從句中充當時間，地點或原因狀語的“介詞+關系詞”結構可以同關系副詞when 和where 互換。
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?
as, which非限定性定語從句
由as, which 引導的非限定性定語從句，as和which可代整個主句，相當于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.典型例題
1）Alice received an invitation from her boss, ___came as a surprise.A.itB.thatC.whichD.he
答案C.此為非限定性從句，不能用 that修飾，而用which.，it 和he 都使后句成為句子，兩個獨立的句子不能單以逗號連接。況且選he句意不通。
2）The weather turned out to be very good, ___ was more than we could expect.A.whatB.whichC.thatD.it
答案B。which可代替句子，用于非限定性定語從句，而what不可。That 不能用于非限定性定語從句，it不為連詞，使由逗號連接的兩個句子并在一起在英語語法上行不通。
3）It rained hard yesterday, ____ prevented me from going to the park..A.thatB.whichC.asD.it
答案B.as 和which在引導非限制性定語從句時，這兩個關系代詞都指主句所表達的整個意思，且在定語從句中都可以作主語和賓語。但不同之處主要有兩點：
(1）as 引導的定語從句可置于句首，而which不可。
(2）as 代表前面的整個主句并在從句中作主語時，從句中的謂語必須是系動詞；若為行為動詞，則從句中的關系代詞只能用which.。
在本題中，prevent由于是行為動詞，所以正確選項應為B。
As 的用法
例1.the same… as；such…as 中的as 是一種固定結構, 和……一樣……。
I have got into the same trouble as he(has).例2.as可引導非限制性從句，常帶有'正如'。
As we know, smoking is harmful to one's health.As is know, smoking is harmful to one's health.As是關系代詞。例1中的as作know的賓語；例2中，它充當從句的主語，謂語動詞know要用被動式。
先行詞和關系詞二合一
1)Whoever spits in public will be punished here.(Whoever 可以用 anyone who 代替)
2)The parents will use what they have to send their son to technical school.(what 可以用all that代替)
what/whatever/that...1)Whoever spits in public will be punished here.(Whoever 可以用 anyone who 代替)
2)The parents will use what they have to send their son to technical school.(what 可以用all that代替)
關系代詞that的用法
1）不用that的情況
a)在引導非限定性定語從句時。
(錯)The tree, that is four hundred years old, is very famous here.b)介詞后不能用。
We depend on the land from which we get our food.We depend on the land that/which we get our food from.2)只能用that作為定語從句的關系代詞的情況
a)在there be 句型中，只用that，不用which。
b)在不定代詞，如：anything, nothing, the one, all, much, few, any, little等作先行詞時，只用that，不用which。
c)先行詞有the only, the very修飾時，只用that。
d)先行詞為序數詞、數詞、形容詞最高級時，只用that。.e)先行詞既有人，又有物時。
舉例：
All that is needed is a supply of oil.所需的只是供油問題。

高中英語語法--定語從句
定語從句在句中做定語，修飾一個名詞或代詞，被修飾的名詞詞組或代詞即先行詞。定語從句通常
出現在先行詞之后，由關系詞（關系代詞或關系副詞）引出。
關系代詞有：who, whom, whose, that, which等。
關系副詞有：when, where, why等。
18.1 關系代詞引導的定語從句
關系代詞所代替的先行詞是人或物的名詞或代詞，并在句中充當主語、賓語、定語等成分。關系代詞在定語從句中作主語時，從句謂語動詞的人稱和數要和先行詞保持一致。
1）who, whom, that
這些詞代替的先行詞是人的名詞或代詞，在從句中作主語和賓語。例如：
Is he the man who/that wants to see you? 他就是你想見的人嗎？（who/that在從句中作主語）
He is the man whom/ that I saw yesterday.他就是我昨天見的那個人。（whom/that在從句中作賓語）
2）whose 用來指人或物，（只用作定語, 若指物，它還可以同of which互換）。例如：
They rushed over to help the man whose car had broken down.那人車壞了，大家都跑過去幫忙。
Please pass me the book whose（of which）cover is green.請遞給我那本綠皮的書。
3）which, that所代替的先行詞是事物的名詞或代詞，在從句中可作主語、賓語等。例如：
A prosperity which / that had never been seen before appears in the countryside.農村出現了前所未有的繁榮。（which / that在句中作賓語）
The package（which / that）you are carrying is about to come unwrapped.你拿的包快散了。（which / that在句中作賓語）
18.2 關系副詞引導的定語從句
關系副詞可代替的先行詞是時間、地點或理由的名詞，在從句中作狀語。
1）關系副詞when, where, why的含義相當于“介詞+ which”結構，因此常常和“介詞+ which”結構交替使用。例如：
There are occasions when（on which）one must yield.任何人都有不得不屈服的時候。
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? 這就是他拒絕我們幫助他的理由嗎？
2）that代替關系副詞，可以用于表示時間、地點、方式、理由的名詞后取代when, where, why和“介+which”引導的定語從句，在口語中that常被省略。例如：
His father died the year（that / when / in which）he was born.他父親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過的地方。
及物動詞和不及物動詞
A 有些動詞只是及物動詞;它們不可以單獨用，后面必須跟賓語。
{ False: They always want after lunch.Right: They always want a cup of tea after lunch.{ False: He is sending now.Right: He is sending a letter now.B 有些動詞只是不及物動詞；它們可以單獨用，如果后面想接賓語，動詞后面必須加上介詞。
18.6 as, which 非限定性定語從句
由as, which 引導的非限定性定語從句，as和which可代整個主句，相當于and this或and that。As一般放在句首，which在句中。例如：
As we know, smoking is harmful to one's health.如我們所知，吸煙有害健康。
The sun heats the earth, which is very important to us.太陽使地球暖起來，這對我們人類很重要。
典型例題
1）Alice received an invitation from her boss, ___came as a surprise.A.it
B.that
C.which
D.he
答案C.此為非限定性從句，不能用 that修飾，而用which.，it 和he 都使后句成為句子，兩個獨立的句子不能單以逗號連接。況且選he句意不通。
2）The weather turned out to be very good, ___ was more than we could expect.A.what B.which C.that D.it
答案B。which可代替句子，用于非限定性定語從句，而what不可。That 不能用于非限定性定語從句，it不為連詞，使由逗號連接的兩個句子并在一起在英語語法上行不通。
3）It rained hard yesterday, ____ prevented me from going to the park..A.that B.which
C.as
D.it
答案B.as 和which在引導非限制性定語從句時，這兩個關系代詞都指主句所表達的整個意思，且在定語從句中都可以作主語和賓語。但不同之處主要有兩點：
（1）as 引導的定語從句可置于句首，而which不可。
（2）as 代表前面的整個主句并在從句中作主語時，從句中的謂語必須是系動詞；若為行為動詞，則從句中的關系代詞只能用which.。在本題中，prevent由于是行為動詞，所以正確選項應為B。
as 的用法
例1.the same…as；such…as 中的as 是一種固定結構, 和……一樣……。例如：
I have got into the same trouble as he（has）.我碰到了跟他一樣的麻煩。
例2.as可引導非限制性從句，常帶有'正如'。例如：
As we know, smoking is harmful to one's health.如我們所知，吸煙有害健康。
As is known, smoking is harmful to one's health.As是關系代詞。例1中的as作know的賓語；例2中，它充當從句的主語，謂語動詞know要用被動式。
18.7 先行詞和關系詞二合一
1）Whoever spits in public will be punished here.（Whoever 可以用 anyone who 代替）
2）The parents will use what they have to send their son to technical school.（what 可以用all that代替）
18.8 what/whatever;that/what;who/whoever
1）what = the thing which；whatever = anything。例如：
What you want has been sent here.你要的動詞都送來了。
Whatever you want makes no difference to me.不管你要什么，跟我沒什么關系。
2）who= the person that
whoever= anyone who。例如：
（錯）Who breaks the law will be punished.（錯）Whoever robbed the bank is not clear.（對）Whoever breaks the law will be punished.王子犯法，與庶民同罪。
（對）Who robbed the bank is not clear.誰搶了銀行還不清楚。
3）that 和 what
當that引導定語從句時，通常用作關系代詞，而引導名詞性從句時，是個不充當任何成分的連接詞。賓語從句和表語從句中的that常可省略。What只能引導名詞性從句，用作連接代詞，作從句的具體成分，且不能省略。例如：
A.of whom B.from whom C.about that D.who 14.In fact the Swede did not understand the three questions ____ were asked in French.A.where
B.who
C.in which D.which 15.Have you read the book ____ I lent to you? A.that B.whom C.when D.whose 16.Finally, the thief handed over everything ____ he had stolen to the police.A.that

定語從句
導入：
e.g.she is a beautiful girl.she is a beautiful girl who drives me crazy.（一）定語從句定義
1.定語從句：在復合句中，修飾某個名詞或代詞的句子（做這個名詞或代詞的定語）叫定語從句，定語從句一般放在被修飾的名詞或代詞后面，2.先行詞：被修飾的名詞或代詞叫做定語從句的先行詞。3.用來引導定語從句的詞叫做關系詞。
關系代詞的種類：
關系代詞that, which, who, whose, 關系副詞： when, where, why 4.定語從句結構：先行詞+關系詞+定語從句。
1.there she saw a wall of water that was quickly advancing towards her.2.in japan, someone who sees another person making the gesture will think it means money.4.the park has a conservation center that helps protect marine animals and their habitats in the rivers and coastal waters of asia.5.visitors can go on exciting rides where they can feel what it is like to do the things they have seen their heroes do in the movie.6.oprah winfrey is a black woman whose rise to fame is an inspiring story.（二）定語從句分類
限定性定語從句：從句對先行詞進行必要的描述或說明，對先行詞起修飾限定
作用，從句與先行詞緊密相連缺少它，則句義顯得不完整，一般不用逗號隔開。
非限定性定語從句：對先行詞進行補充說明，解釋，它與先行詞關系松散，用
逗號隔開。
1.the man who gave me this book is tom.(限定性)2.tom,who is reading a book ,is my classmate(非限定性)
（三）關系代詞 1.who指人，在定語從句中作主語，口語中可做賓語；that 也可指人，但多用 who.e.g.the man who is sitting under the tree is a german.2.whom指人，在句中做賓語，可省略，但在做介詞的賓語是只能用whom,不
能用who.關系代詞前有介詞時不能省略。
e.g.the man(whom)you look for has left.i know the girl(whom)the teacher is speaking to.i know the girl to whom the teacher is speaking.3.whose, 作定語，可指人或物
e.g.everyone heplps the child whose parents are dead.they are the lazy students whose homework wasn‘t handed in.針對練習

只能that用做關系代詞的情況（共9種類型）。
1.當先行詞是all, everything, anything, nothing, much, little, none, one等不定代詞時，只用that。歌訣助記：不定代詞這路貨，全用that準沒錯。pay attention to everything that i do.2.當先行詞被序數詞或形容詞最高級修飾時，只用that。
歌訣助記：先行詞前被限定，千萬不要用which.this is the best novel(that)have read.3.如果出現兩個或兩個以上的先行詞，并同時兼指人和物時，關系代詞用that。歌訣助記：兩項并列人與物，引導定從用that.they were talking about the person and things that they remembered in school.4.當先行詞被the only, the last, the way, the same等等修飾時。this is the last time that i shall give you a lesson.5.在疑問詞which開頭的特殊疑問句中,為了避免重復只用that。which of the students that knows something about history.6.當先行詞被all, every, no, some, any, little, much等修飾時，只用that。he has little time that he can spare.7.當被修飾的成分是數詞時，（被修飾成分是代名詞one，指人時除外）只用that.i‘ve got one that you might be interested in.（3）用which，不用that的情況
①引導非限制性定語從句。
e.g.football, which is an interesting game, is played all over the world.全世界都踢足球，它是一項有趣的運動。
carol said the work would be done by october, which personally i doubt very much.卡羅爾說這項工作將在十月前做，對此我個人表示懷疑。dorothy was always speaking highly of her role in the play, which ,of course, made the others unhappy.桃樂茜總是吹噓她在戲劇中的角色，這當然使別人不高興。
②直接放在介詞后作賓語時。a.whichb.wherec.when d.as 2011the old town has narrow streets and small houses _____are built close to each other.a.they b.where c.what d.that a.which b.wherec.what d.who a.who b.wherec.when d.which 5.〖10全國ⅱ〗i refuse to accept the blame for something ________was someone else‘s fault.a.whob.that c.asd.what
（四）關系副詞 1.when 指時間
（1）在定語從句中作狀語，先行詞主要為一些時間名詞（year ,day ,time,week 等）,但時間名詞在從句中作主語，賓語時，應用that，which，不能用when 做主語 i‘ll never forget the time 作狀語 做主語
做賓語
he rememberes the days when he spent much money on stories.(2)it is the first time that ?句型中，that是習慣用法，不用when。e.g.it is the first time that i have been to the great wall.2.where 指地點
（1）指前面的地點，在從句中作狀語。
e.g.i know the factory where i worked twenty years ago.(2)指地點，在句中作主語，賓語時不能用where，須用that/which.e.g.this is the house where he has lived for 20 years.this is the house that he has lived in for 20 years.e.g.this is the shool ｛in which /where we study every year.this is the shool that /which we visited yesterday.注：有時when ,where 相當于“介詞+at/in +which ”.e.g.he left the room where /in which he lived last year.(3)當先行詞為某個方面、情況、階段、位置等的詞時使用關系副詞 3.why表示原因
―the reason why ?.that?.‖中，不能用because 代替that.the reason why he didn‘t attend the meeting is that he was ill.但reason 在從句中做賓語時，關系代詞用that/which ,課省略 e.g.i don‘t believe the reason(which/that)he gave me.關系副詞針對性練習

（五）．“介詞+關系代詞”引導的定語從句
當先行詞在定于從句中作介詞的賓語時，往往可以把介詞放在關系代詞之前，構成“介詞+關系代詞（whom/which）”結構。但一些短語東西如look after 等中的介詞不能與動詞分開，故不能放在關心代詞之前。確定介詞時： 篇三：高中英語語法教學設計 定語從句
高中英語語法教學設計：定語從句講解與練習
定語從句在句中做定語，修飾一個名詞或代詞，被修飾的名詞詞組或代詞即先行詞。定語從句通常
出現在先行詞之后，由關系詞（關系代詞或關系副詞）引出。
關系代詞有：who, whom, whose, that, which等。
關系副詞有：when, where, why等。18.1 關系代詞引導的定語從句
關系代詞所代替的先行詞是人或物的名詞或代詞，并在句中充當主語、賓語、定語等成分。關系代詞在定語從句中作主語時，從句謂語動詞的人稱和數要和先行詞保持一致。1）who, whom, that 這些詞代替的先行詞是人的名詞或代詞，在從句中作主語和賓語。例如：
is he the man who/that wants to see you? 他就是你想見的人嗎？（who/that在從句中作主語）
he is the man whom/ that i saw yesterday.他就是我昨天見的那個人。（whom/that在從句中作賓語）
2）whose 用來指人或物，（只用作定語, 若指物，它還可以同of which互換）。例如： they rushed over to help the man whose car had broken down.那人車壞了，大家都跑過去幫忙。
please pass me the book whose（of which）cover is green.請遞給我那本綠皮的書。3）which, that所代替的先行詞是事物的名詞或代詞，在從句中可作主語、賓語等。例如： a prosperity which / that had never been seen before appears in the countryside.農村出現了前所未有的繁榮。（which / that在句中作賓語）
你拿的包快散了。（which / that在句中作賓語）18.2 關系副詞引導的定語從句
關系副詞可代替的先行詞是時間、地點或理由的名詞，在從句中作狀語。1）關系副詞when, where, why的含義相當于介詞+ which結構，因此常常和介詞+ which結構交替使用。例如： there are occasions when（on which）one must yield.任何人都有不得不屈服的時候。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? 這就是他拒絕我們幫助他的理由嗎？
2）that代替關系副詞，可以用于表示時間、地點、方式、理由的名詞后取代when, where, why和介+which引導的定語從句，在口語中that常被省略。例如：
his father died the year（that / when / in which）he was born.他父親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過的地方。18.3 判斷關系代詞與關系副詞
方法一：用關系代詞，還是關系副詞完全取決于從句中的謂語動詞。及物動詞后面無賓語，就必須要求用關系代詞；而不及物動詞則要求用關系副詞。例如：
this is the mountain village where i stayed last year.這是我去年呆過的山村。ill never forget the days when i worked together with you.我永遠不會忘記與你共事的日子。
判斷改錯：
（錯）this is the mountain village where i visited last year.（錯）i will never forget the days when i spent in the countryside.（對）this is the mountain village（which）i visited last year.（對）ill never forget the days（which）i spent in the countryside.習慣上總把表地點或時間的名詞與關系副詞 where, when聯系在一起。此兩題錯在關系詞的誤用上。
方法二：準確判斷先行詞在定語從句中的成分（主、謂、賓、定、狀），也能正確選擇出關系代詞/關系副詞。
例1.is this museum ___ you visited a few days age? a.where b.that c.on which d.the one 例2.is this the museum ____ the exhibition was held.a.where b.that c.on which d.the one 答案：例1 d，例2 a 例1變為肯定句： this museum is ___ you visited a few days ago.例2變為肯定句： this is the museum ___ the exhibition was held.在句1中，所缺部分為賓語，而where, that, on which都不能起到賓語的作用，只有the one既做了主句的表語，又可做從句的賓語，可以省略關系代詞，所以應選d。
而句2中, 主、謂、賓俱全，從句部分為句子的狀語表地點，既可用副詞where，又因 in the museum詞組，可用介詞in + which 引導地點狀語。而此題中，介詞on 用的不對，所以選a。
關系詞的選擇依據在從句中所做的成分，先行詞在從句中做主、定、賓語時，選擇關系代詞（who, whom, that, which, whose）；先行詞在從句中做狀語時，應選擇關系副詞（where 地點狀語，when 時間狀語，why 原因狀語）。18.4 限制性和非限制性定語從句
1）定語從句有限制性和非限制性兩種。限制性定語從句是先行詞不可缺少的部分，去掉它主句意思往往不明確；非限制性定語從句是先行詞的附加說明，去掉了也不會影響主句的意思，它與主句之間通常用逗號分開。例如：
this is the house which we bought last month.這是我們上個月買的那幢房子。（限制性）
the house, which we bought last month, is very nice.這幢房子很漂亮，是我們上個月買的。（非限制性）
2）當先行詞是專有名詞或物主代詞和指示代詞所修飾時，其后的定語從句通常是非限制性的。例如：
charles smith, who was my former teacher, retired last year.查理?史密斯去年退休了，他曾經是我的老師。
my house, which i bought last year, has got a lovely garden.我去年買的的那幢房子帶著個漂亮的花園。
this novel, which i have read three times, is very touching.這本小說很動人，我已經讀了三遍。
3）非限制性定語從句還能將整個主句作為先行詞, 對其進行修飾, 這時從句謂語動詞要用第三人稱單數。例如：
he seems not to have grasped what i meant, which greatly upsets me.他似乎沒抓住我的意思，這使我心煩。
liquid water changes to vapor, which is called evaporation.液態水變為蒸汽，這就叫做蒸發。
說明：關系代詞that和關系副詞why不能引導非限制性定語從句。18.5 介詞+關系詞
1）介詞后面的關系詞不能省略。2）that前不能有介詞。
3）某些在從句中充當時間，地點或原因狀語的介詞+關系詞結構可以同關系副詞when 和where 互換。例如：
this is the house in which i lived two years ago.這是我兩年前住過的房子。this is the house where i lived two years ago.do you remember the day on which you joined our club? 還記得你加入我們俱樂部的那一天嗎？
do you remember the day when you joined our club? 18.6 as, which 非限定性定語從句
由as, which 引導的非限定性定語從句，as和which可代整個主句，相當于and this或and that。as一般放在句首，which在句中。例如：
as we know, smoking is harmful to ones health.如我們所知，吸煙有害健康。
the sun heats the earth, which is very important to us.太陽使地球暖起來，這對我們人類很重要。
典型例題
1）alice received an invitation from her boss, ___came as a surprise.a.it b.that c.which d.he 答案c.此為非限定性從句，不能用 that修飾，而用which.，it 和he 都使后句成為句子，兩個獨立的句子不能單以逗號連接。況且選he句意不通。
2）the weather turned out to be very good, ___ was more than we could expect.a.what b.which c.that d.it 答案b。which可代替句子，用于非限定性定語從句，而what不可。that 不能用于非限定性定語從句，it不為連詞，使由逗號連接的兩個句子并在一起在英語語法上行不通。3）it rained hard yesterday, ____ prevented me from going to the park..a.that b.which c.as d.it 答案b.as 和which在引導非限制性定語從句時，這兩個關系代詞都指主句所表達的整個意思，且在定語從句中都可以作主語和賓語。但不同之處主要有兩點：
（1）as 引導的定語從句可置于句首，而which不可。
（2）as 代表前面的整個主句并在從句中作主語時，從句中的謂語必須是系動詞；若為行為動詞，則從句中的關系代詞只能用which.。在本題中，prevent由于是行為動詞，所以正確選項應為b。as 的用法
例1.the same?as；such?as 中的as 是一種固定結構, 和??一樣??。例如： i have got into the same trouble as he（has）.我碰到了跟他一樣的麻煩。
例2.as可引導非限制性從句，常帶有正如。例如：
as we know, smoking is harmful to ones health.如我們所知，吸煙有害健康。as is known, smoking is harmful to ones health.as是關系代詞。例1中的as作know的賓語；例2中，它充當從句的主語，謂語動詞know要用被動式。
18.7 先行詞和關系詞二合一
1）whoever spits in public will be punished here.（whoever 可以用 anyone who 代替）
2）the parents will use what they have to send their son to technical school.（what 可以用all that代替）
18.8 what/whatever;that/what;who/whoever 1）what = the thing which；whatever = anything。例如： what you want has been sent here.你要的動詞都送來了。
whatever you want makes no difference to me.不管你要什么，跟我沒什么關系。
（錯）who breaks the law will be punished.（錯）whoever robbed the bank is not clear.（對）whoever breaks the law will be punished.王子犯法，與庶民同罪。
