能总结定语从句的语法吗

Question

如题所述

Answer 1

【烛光】团队为您解答：

关系代词所代替的先行词是人或物的名词或代词，并在句中充当主语、宾语、定语等成分。关系代词在定语从句中作主语时，从句谓语动词的人称和数要和先行词保持一致。
1）who, whom, that
这些词代替的先行词是人的名词或代词，在从句中所起作用如下：
Is he the man who/that wants to see you?
他就是想见你的人吗？（who/that在从句中作主语）
He is the man whom/ that I saw yesterday.
他就是我昨天见的那个人。（whom/that在从句中作宾语）

2) Whose 用来指人或物，(只用作定语, 若指物，它还可以同of which互换）, 例如：
They rushed over to help the man whose car had broken down. 那人车坏了，大家都跑过去帮忙。
Please pass me the book whose (of which) cover is green. 请递给我那本绿皮的书。

3）which, that
它们所代替的先行词是事物的名词或代词，在从句中可作主语、宾语等，例如：
A prosperity which / that had never been seen before appears in the countryside. 农村出现了前所未有的繁荣。（which / that在句中作宾语）
The package (which / that) you are carrying is about to come unwrapped. 你拿的包快散了。(which / that在句中作宾语）

关系副词引导的定语从句

关系副词可代替的先行词是时间、地点或理由的名词，在从句中作状语。
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。

判断关系代词与关系副词

方法一： 用关系代词，还是关系副词完全取决于从句中的谓语动词。及物动词后面无宾语，就必须要求用关系代词；而不及物动词则要求用关系副词。例如：
This is the mountain village where I stayed last year.
I'll never forget the days when I worked together with you.

判断改错（注：先显示题，再显示答案，横线；用不同的颜色表示出。）
（错） This is the mountain village where I visited last year.
（错） I will never forget the days when I spent in the countryside.
（对） This is the mountain village (which) I visited last year.
（对） I'll never forget the days (which) I spent in the countryside.

习惯上总把表地点或时间的名词与关系副词 where, when联系在一起。此两题错在关系词的误用上。

方法二： 准确判断先行词在定语从句中的成分(主、谓、宾、定、状)，也能正确选择出关系代词/关系副词。
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变为肯定句： This museum is ___ you visited a few days ago.
例2变为肯定句： This is the museum ___ the exhibition was held.
在句1中，所缺部分为宾语，而where, that, on which都不能起到宾语的作用，只有the one既做了主句的表语，又可做从句的宾语，可以省略关系代词，所以应选D。
而句2中, 主、谓、宾俱全，从句部分为句子的状语表地点，既可用副词where，又因 in the museum词组，可用介词in + which 引导地点状语。而此题中，介词on 用的不对，所以选A。
关系词的选择依据在从句中所做的成分，先行词在从句中做主、定、宾语时，选择关系代词 (who, whom, that, which, whose)； 先行词在从句中做状语时，应选择关系副词 ( where 地点状语，when 时间状语，why 原因状语) 。

限制性和非限制性定语从句

1) 定语从句有限制性和非限制性两种。限制性定语从句是先行词不可缺少的部分，去掉它主句意思往往不明确；非限制性定语从句是先行词的附加说明，去掉了也不会影响主句的意思，它与主句之间通常用逗号分开，例如：
This is the house which we bought last month. 这是我们上个月买的那幢房子。（限制性）
The house, which we bought last month, is very nice.这幢房子很漂亮，是我们上个月买的。（非限制性）
2) 当先行词是专有名词或物主代词和指示代词所修饰时，其后的定语从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，他曾经是我的老师。
My house, which I bought last year, has got a lovely garden. 我去年买的的那幢房子带着个漂亮的花园。
This novel, which I have read three times, is very touching. 这本小说很动人，我已经读了三遍。

3) 非限制性定语从句还能将整个主句作为先行词, 对其进行修饰, 这时从句谓语动词要用第三人称单数，例如：
He seems not to have grasped what I meant, which greatly upsets me. 他似乎没抓住我的意思，这使我心烦。
Liquid water changes to vapor, which is called evaporation. 液态水变为蒸汽，这就叫做蒸发。

说明：关系代词that和关系副词why不能引导非限制性定语从句。

介词+关系词

1）介词后面的关系词不能省略。
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 和where 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?

as, which 非限定性定语从句

由as, which 引导的非限定性定语从句，as和which可代整个主句，相当于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.

典型例题
1）Alice received an invitation from her boss, ___came as a surprise.
A. it B. that C. which D. he
答案C. 此为非限定性从句，不能用 that修饰，而用which.，it 和he 都使后句成为句子，两个独立的句子不能单以逗号连接。况且选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，用于非限定性定语从句，而what不可。That 不能用于非限定性定语从句，it不为连词，使由逗号连接的两个句子并在一起在英语语法上行不通。

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在引导非限制性定语从句时，这两个关系代词都指主句所表达的整个意思，且在定语从句中都可以作主语和宾语。但不同之处主要有两点：
(1） as 引导的定语从句可置于句首，而which不可。
(2） as 代表前面的整个主句并在从句中作主语时，从句中的谓语必须是系动词；若为行为动词，则从句中的关系代词只能用which.。
在本题中，prevent由于是行为动词，所以正确选项应为B。

As 的用法
例1. the same… as；such…as 中的as 是一种固定结构, 和……一样……。
I have got into the same trouble as he (has).
例2. as可引导非限制性从句，常带有'正如'。
As we know, smoking is harmful to one's health.
As is know, smoking is harmful to one's health.
As是关系代词。例1中的as作know的宾语；例2中，它充当从句的主语，谓语动词know要用被动式。

先行词和关系词二合一

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/what; who/whoever

1）what = the thing which；whatever = anything
What you want has been sent here.
Whatever you want makes no difference to me.
2) who= the person that whoever= anyone who
（错）Who breaks the law will be punished.
（错）Whoever robbed the bank is not clear.
（对）Whoever breaks the law will be punished.
（对）Who robbed the bank is not clear.
3) that 和 what
当that引导定语从句时 ，通常用作关系代词，而引导名词性从句时，是个不充当任何成分的连接词。宾语从句和表语从句中的that常可省略。What只能引导名词性从 句， 用作连接代词，作从句的具体成分，且不能省略。
I think (that) you will like the stamps.
What we need is more practice.

关系代词that 的用法

1）不用that的情况
a) 在引导非限定性定语从句时。
(错) The tree, that is four hundred years old, is very famous here.
b) 介词后不能用。
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作为定语从句的关系代词的情况
a) 在there be 句型中，只用that，不用which。
b) 在不定代词，如：anything, nothing, the one, all, much, few, any, little等作先行词时，只用that，不用which。
c) 先行词有the only, the very修饰时，只用that。
d) 先行词为序数词、数词、形容词最高级时，只用that。.
e) 先行词既有人，又有物时。

举例：
All that is needed is a supply of oil.
所需的只是供油问题。
Finally, the thief handed everything that he had stolen to the police.
那贼最终把偷的全部东西交给了警察。

Answer 2

(一)定语从句的结构:在复合句中,修饰某个名词或代词的句子(做这个名词或代词的定语)叫定语从句,定语从句一般放在被修饰的名词或代词后面,被修饰的名词或代词叫做定语从句的先行词,它与定语从句之间要有一个词连接,这个词指代先行词的内容叫做关系词(关系代词或关系副词:that, which, who, whose, when, where, why)。先行词在定语从句中充当主语,宾语,时间,地点,原因状语。
结构:先行词+关系词+定语从句。
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.
3. A theme park is a collection of rides, exhibitions or other attractions that are based on a common theme.
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)定语从句分为限定性定语从句和非限定性定语从句:
限定性定语从句:从句对先行词进行必要的描述或说明,缺少它,则句义显得不完整,从句与先行词紧密相连。
非限定性定语从句:对先行词进行补充说明,解释,它与先行词之间有逗号隔开。
1. Before she could move, she heard a loud noise, which grew to a terrible roar.
2. Tree after tree went down, cut down by the water, which must have been three meters deep.
3. Flora, whose beautiful hair and dress were all cold and wet, started crying.
4. Their talk includes rhythm and rhyming words as well as tongue twisters, which often make the audience applaud.
(三)关系词前面可以根据定语从句的内容加上一些介词,这些关系词在介词后面常用which 或whom.
1. There was a man with whom I would have to work together and finally the manager of the company.
2. Many people who saw the film were afraid to swim in the sea when they remembered the scenes in which people were eaten by the shark.
知识重点与难点
(一)当先行词有最高级,序数词修饰,是不定代词,或是all, no, only等形式时,关系代词一般用that,而不能用which。
1. The Titanic was the largest ship that had ever been built at that time.
2. There is one thing that keeps worrying me.
(二)当先行词是表示时间,地点,原因的词时,关系词用when, where, why 还有which, that
1. I'm very glad to return to my hometown where I had lived for 10 years.
2. This is my hometown which I used to talk about to you.
3. I think I can understand the reason why he didn't tell the truth to me.
4. No one believes the reason that he gave us about his absence at the meeting.
(三)定语从句的简化表达:
1. The man who is sitting on the platform is a professor from Wuhan University.
2. The letter that was mailed last night will reach him tomorrow.
3. The question that is being discussed is very important.
4. You are welcome to a party to be given in our class at 7:45.
说明:以上的定语从句部分可以用更加简单的非谓语形式表达出来:
1. The man sitting on the platform is a professor from Wuhan University.
2. The letter mailed last night will reach him tomorrow.
3. The question being discussed is very important.
4. You are welcome to a party to be given in our class at 7:45.
说明:修饰一个名词除了后面用定语从句以外,还可以用非谓语动词形式:doing短语,done短语,being done短语,to be done短语修饰。其结构和意思如下:
1. 被修饰名词+doing短语: 正在做….的人/正在发生的事。
2. 被修饰名词+ done短语: 被…..的人/事
3. 被修饰名词+being done短语:正在被…..的人/事
4. 被修饰名词+ to be done短语:将要被…..的人/事
(1)Do you know the man talking to my sister ?
(2)The "crazy" gesture, moving the index finger in a circle in front of the ear, means "you have a phone call" in Brazil.
(3)Did you see that car being repaired ?
(4)In a camera, the lens must be focused on the object to be photographed.
(5)The students to attend the meeting will arrive here tomorrow.
(7)The Yellow River, said to be "the mother river" runs across China like a huge dragon.
总结:以上做定语的那些短语就是英语语法中所说的分词,不定式的各种形式作定语。
1. 这些短语作定语应放在被修饰名词的后面。如果单独一个V-ing或V-ed形式作定语,则可以放在被修饰名词前面。
2. 分词作定语时,其动作应与全句动作同时发生。V-ing表示主动意义和正在做,V-ed表示被动意义。being done表示正在被做的
3. 不定式作定语表示将要发生的,to be done表示将要被做的

Answer 3

在复合句中用作定语的从句称为定语从句。定语从句通常位于所修饰的名词或代词之后，常由关系代词或关系副词引出，被修饰的词称为先行词。常见的关系代词有：who\whom\which\that\whose,关系副词有：when\why\where.
一、先行词为指人的名词或代词时，定语从句用who或that来引导。例如：Do you know the girl who is in a red dress.你认识那个穿红衣服的女孩吗？
The man who we saw that day hasn't come here yet.那天我们见到的那个人还没有来这儿。
二、先行词是指物的名词或代词时，用which或that, which或that在从句中做主语或宾语。例如：She works in a shoe factory which\that is far from here.她在离这儿很远的一家鞋厂工作。
三、只能用关系代词that引导的几种情况：A、当先行词是anything,nothing,everything等不定代词时。例如：I'm sorry to tell you that there is nothing that I can do for you.很抱歉告诉你，我帮不上忙。
Is there anything that you want to buy in town?你在城里有什么东西要买吗？
B、当先行词是最高级或被最高级修饰时。例如：This is the best way that can solve the problem.这是解决问题的最好方法。
This is the most beautiful flower that I have seen.这是我看到的最美的花。
C、当先行词被first,last,only,very,no,just,any,little等词修饰时。例如：She asked for the last book that was on the subject.她要了有关这个科目的最后一本书。
This is the only one that I'm looking for.这是我正在找的唯一的一个。
四、who引导的定语从句
A、who引导的定语从句的先行词为表示人的名词或代词。例如：The boy who is standing under the tree is Peter.
B、who在定语从句中作主语时不能省略；但在非正式的英语中，who也可作宾语，且可以省略。例如：The person who was here yesterday is a teacher.
The man (who) I saw just now is Mr Liu.
C、在定语从句中，who在人称、数上和其前面的先行词保持一致。例如：Do you know the boy who is standing over there?
D、若先行词中既有人又有物，关系代词用that，而不用who。例如：He watched the children and boxes that filled the car.他看见了塞满汽车的孩子和盒子。
E、若先行词前面有形容词最高级、序数词修饰，关系代词用that而不用who。例如：Yao Ming is the best basketball player that I kown.
五、当先行词为地点名词时，用关系副词where引导。例如：This is the place where we came last summer.
六、当先行词为表示时间的名词时，用关系副词when来引导。例如：She came on the day when I was not at home.她来的那天我不在家。
这些都是我上课做的笔记，唔，码字好辛苦的~~手都酸了，不过对我自己也有帮助的呢，我也复习了一遍……(*^__^*) 嘻嘻……希望对你有所帮助。
