主语从句和定语从句怎么区分?我有点混了?能举个例子解释一下吗?谢谢大家了!
栗子先放一下。所谓形式主语一般是出于句子结构原因(主语太长)而使用的,大部分情况下是it引导。真正的主语一般是动词后面的不定式(to do)或动名词(ing)例如
It is my duty to care for that patient
这里to care for that patient就是真正的主语。放到后面是让句子更美观(英美的逻辑)
定语,即是对主语或宾语的补充说明,可以把整个句子视为一个形容词,例如
He is Tom,who is the owner of that dog.
who后面引导的就是定语从句对TOM这个宾语的补充说明,但是即使把who后面所有内容全部删除,也不影响HE IS TOM这个句子本身的意思。换句话说,定语的存在在句子整体中是可有可无的。
另外任何句子,只要是完整的句子,必须至少有主语,谓语。 所以区分形式主语和定语的一个基本前提就是这个句子缺少了这个词或句子,还完整通顺吗?

定语从句是由关系代词和关系副词引导的从句,其作用是作定语修饰主句的某个名词性成分,定语从句分为限定性和非限定性从句两种。
(一) 限定性定语从句
1. that即可代表事物也可代表人,which代表事物;它们在从句中作主语或宾语,that在从句中作宾语时常可省略关系词,which在从句中作宾语则不能省略。而且,如果which在从句中作“不及物动词+介词”的介词的宾语,注意介词不要丢掉,而且介词总是放在关系代词which的前边,但有的则放在它原来的位置
2. which作宾语时,根据先行词与定语从句之间的语义关系,先行词与which之间的介词不能丢
3. 代表物时多用which,但在带有下列词的句子中用that而不用which,这些词包括all, anything, much等,这时的that常被省略
4. who和whom引导的从句用来修饰人,分别作从句中的主语和宾语,whom作宾语时,要注意它可以作动词的宾语也可以作介词的宾语
5. where是关系副词,用来表示地点的定语从句
6. when引导定语从句表示时间
〔注〕值得一提的是,表示时间“time"一词的定语从句只用when引导,有时不用任何关系代词,当然也不用that引导
By the time you arrive in London, we will have stayed there for two weeks.
I still remember the first time I met her.
Each time he goes to business trip, he brings a lot of living necessities, such as towers, soap, toothbrush etc.
7. whose是关系代词,修饰名词作定语,相当于所修饰成分的前置所有格
8. 当从句的逻辑主语是some, any, no, somebody, anybody, nobody, something, anything, everything或nothing时,常用there is来引导
(二)非限定性定语从句:
非限定性定语从句的作用是对所修饰的成分作进一步说明,通常和主句间用逗号隔开,将从句拿掉后其他部分仍可成立
1. which引导的非限定性定语从句来说明前面整个句子的情况或主句的某一部分
2. 在引导限定性定语从句时,that有时相当于in which, at which, for which或at which
Attitudes towards daydreaming are changing in much the same way that(in which) attitudes towards night dreaming have changed. 人们对白日做梦的态度正在改变,这与人们对夜间做梦的看法的变化有非常相似之处。
I like the music for the very reason that(for which) he dislike it. 我出于某种原因喜欢这种音乐,而他恰恰与我相反。
We arrived the day that(on which) they left. 刚好我们到的那天他们走了。
3. 有时as也可用作关系代词
4. 在非限定性定语从句中,不能用that,而用who, whom代表人,用which代表事物.
一.定语从句及相关术语
1.定语从句:修饰一个名词或代词的从句称为定语从句,一般紧跟在它所修饰的先行词后面。
2.关系词:引导定语从句的关联词成为关系词
关系词有关系代词和关系副词。关系代词有that, which, who, whom, whose, as等;关系副词有where, when, why等。
关系词常有3个作用:1,引导定语从句。2,代替先行词。3,在定语从句中担当一个成分。
二.关系代词引导的定语从句
1.who指人,在从句中做主语
(1) The boys who are playing football are from Class One.
(2) Yesterday I helped an old man who lost his way.
2. whom指人,在定语从句中充当宾语,常可省略。
(1) Mr. Liu is the person (whom) you talked about on the bus.
(2) Mr. Ling is just the boy whom I want to see.
注意:关系代词whom在口语和非正式语体中常用who代替,可省略。
(3) The man who/whom you met just now is my friend.
3. which指物,在定语从句中做主语或者宾语,做宾语时可省略
(1) Football is a game which is liked by most boys.
(2) This is the pen (which) he bought yesterday.
如果在从句中做宾语,就用whom或who.比如:
He is the man whom/who I talk to.
如果是在从句中作主语就只能用who.比如:
He is the man who has an English book.
4. that指人时,相当于who或者whom;指物时,相当于which。在定语从句中做主语或者宾语,做宾语时可省略。
(5) The number of the people that/who come to visit the city each year rises one million.
(6) Where is the man that/whom I saw this morning?
5. whose通常指人,也可指物,在定语从句中做定语
(1) He has a friend whose father is a doctor.
(2) I once lived in a house whose roof has fallen in.
whose指物时,常用以下结构来代替
(3) The classroom whose door is broken will soon be repaired.
(4) The classroom the door of which is broken will soon be repaired.
(5) Do you like the book whose cover is yellow?
(6) Do you like the book the color of which is yellow?
三.介词+关系代词引导的定语从句
关系代词在定语从句中做介词宾语时,从句常由介词+关系代词引导
(1) The school (that/which) he once studied in is very famous.
(2) The school in which he once studied is very famous.
(3) Tomorrow I will bring here a magazine (that/which) you asked for.
(4) Tomorrow I will bring here a magazine for which you asked.
(5) We’ll go to hear the famous singer (whom/that/who) we have often talked about.
(6) We’ll go to hear the famous singer about whom we have often talked.
注意:
1. 含有介词的动词短语一般不拆开使用,如:look for, look after, take care of等
(1) This is the watch which/that I am looking for. (T)
(2) This is the watch for which I am looking. (F)
2. 若介词放在关系代词前,关系代词指人时用whom,不可用who或者that;指物时用which,不能用that;关系代词是所有格时用whose
(1) The man with whom you talked is my friend. (T)
(2) The man who/that you talked with is my friend. (F)
(3) The plane in which we flew to Canada is very comfortable. (T)
(4) The plane in that we flew in to Canada is very comfortable. (F)
3. “介词+关系代词”前可有some, any, none, both, all, neither, most, each, few等代词或者数词
(1) He loved his parents deeply, both of whom are very kind to him.
(2) In the basket there are quite many apples, some of which have gone bad.
(3) There are forty students in our class in all, most of whom are from big cities.
四.关系副词引导的定语从句
1. when指时间,在定语从句中做时间状语
(1) I still remember the day when I first came to the school.
(2) The time when we got together finally came.
2. where指地点,在定语从句中做地点状语
(1) Shanghai is the city where I was born.
(2) The house where I lived ten years ago has been pulled down.
3. why指原因,在定语从句中做原因状语
(1) Please tell me the reason why you missed the plane.
(2) I don’t know the reason why he looks unhappy today.
注意:关系副词引导的从句可以由“介词+关系代词”引导的从句替换
(1) The reason why/ for which he refused the invitation is not clear,
(2) From the year when/in which he was going to school he began to know what he wanted when he grew up.
(3) Great changes have taken place in the city in which./where I was born.
五.限制性定语从句和非限制性定语从句
限制性定语从句 非限制性定语从句
形式上 不用逗号和主句隔开 用逗号和主句隔开
意义上 是先行词不可缺少的定语,不能删除 是对先行词的补充说明,删除后意思仍完整
译法上 翻译成先行词的定语,“…的…” 通常翻译成主句的并列句
关系词的使用上 A.做宾语时可省略 B。可用that
C.可用who代替whom A.不可省 B。不用that
C。不用who代替whom
限制性定语从句举例:
(1) The teacher told me that Tom was the only person that I could depend on.
(2) China is a country which has a long history.
非限制性定语从句举例:
(1) His mother, who loves him very much, is strict with him.
(2) China, which was founded in 1949, is becoming more and more powerful.
要注意区分以下几个句子的不同
(1) His brother who is now a doctor always encourages him to go to college.
他那当医生的哥哥常鼓励他要考上大学。(他还有其他的哥哥)
(2) His brother, who is now a doctor, always encourages him to go to college.
他的哥哥是当医生的,常鼓励他要考上大学。(他只有一个哥哥)
六、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) 。
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?
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)
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。
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。
难点分析
(一)限制性定语从句只能用that的几种情况
1.当先行词是anything, everything, nothing (something 除外), few, all, none, little, some等代词时,或者是由every, any, all, some, no, little, few, much等修饰时
(1) Have you taken down everything that Mr. Li has said?
(2) There seems to be nothing that seems impossible for him in the world.
(3) All that can be done has been done.
(4) There is little that I can do for you.
注意:当先行词指人时,偶尔也可以用who
(4) Any man that/.who has a sense of duty won’t do such a thing.
2. 当先行词被序数词修饰
(1) The first place that they visited in London was the Big Ben.
3. 当先行词被形容词最高级修饰时
(1) This is the best film that I have seen.
4. 当形容词被the very, the only 修饰时
(1) This is the very good dictionary that I want to buy,
(2) After the fire in his house, the old car is the only thing that he owned.
当先行词指人时,偶尔也可以用who
(3) Wang Hua is the only person in our school who will attend the meeting/
5. 当先行词前面有who, which等疑问代词时
(1) Who is the man that is standing there?
(2) Which is the T-shirt that fits me most?
6. 当先行词既有人,也有动物或者物体时
(1) Can you remember the scientist and his theory that we have learned?
(二)关系代词as和which引导的定语从句
as和which引导非限制性定语从句,有相同之处也有不同之处。具体情况是:
1.As和which都可以在定语从句中做主语或者宾语,代表前面整个句子。
(1) He married her, as/which was natural.
(2) He was honest, as/which we can see.
2. as 引导非限制性定语从句,可放在主句之前,或者主句之后,甚至可以切割一个主句;which引导的非限制性定语从句只能放在主句之后。另外,as有“正如……,正像……”的意思
(1) As is known to all, China is a developing country.
(2) He is from the south, as we can see from his accent.
(3) John, as you know, is a famous writer.
(4) He has been to Paris more than several times, which I don’t believe.
注意:当主句和从句存在逻辑上的因果关系时,常用which
(5) Tom was always late for school, which made his teacher angry.
3. 当先行次受such, the same修饰时,常用as
(1) I have never heard such a story as he tells.
(2) He is not such a fool as he looks.
(3) This is the same book as I lost last week.
注意:当先行次由the same修饰时,偶尔也用that引导定语从句,但是和由as所引导的定语从句意思不同
(4) She wore the same dress that she wore at Mary’s wedding. 她穿着她在MARY婚礼上穿过的一条裙子。
(5) She wore the same dress as her young sister wore. 她穿着和她妹妹所穿的一样的裙子。
(三)以the way为先行词的定语从句通常由in which, that引导,而且通常可以省略。
(1) The way in which/ that/./ he answered the question was surprising.
(四) but有时也可以做关系词引导定语从句
(1) There are very few but understand his idea. ( but= who don’t )
(五) 区分定语从句和同位语从句
1.定语从句修饰先行词,它和先行词是修饰关系;同位语从句说明先行词的具体内容,是补充说明的关系
(1) The plane that has just taken off is for London. 定语从句
(2) The fact that he has been dead is clear. 同位于从句
2.定语从句由关系代词或者关系副词引导,关系词在句中充当成分,有时可以省略;同位语从句主要由that引导,在句中一般不做成分;句子也可以由when, where, how, why, whether, what等词引导,充当成分
(1) The news he told me is true.
(2) The news that he has just died is true.
(3) The problem that we are facing now is how we can collect so much money. 定语
(4) The problem how we can collect so much money is difficult to solve.
3. 同位语从句和先行词一般可以用be动词发展成一个完整的句子,而定语从句不可以
(1) The idea that we could ask the teacher for advice is wonderful. 同位语
(2) The idea was that we could ask the teacher for advice.
(3) The fact that the earth moves around the earth is known to all.
What I need is a book.
这个句子很显然谓语是is,宾语是 book。那么谓语前就应该是主语,即what I need (我需要的)
同样举一个定从的例子,
What I need is a book which has many pictures.
主语依然是what I need,这时候宾语也依然是book,主谓宾都不缺了吧,所以which……就是修饰book的 即“带有图片的”书,which引导的是定语从句。
主语从句你就把这个从句理解成主语就行。定语从句一般是对先行词进行修饰,就跟形容词和名词之间的关系一样。
英语名词性从句和定语从句怎么做?
2)同位语从句与定语从句的区别在于:定语从句是对先行词加以修饰、限制,而同位语从句是为了说明中心词的具体内容;that在定语从句中充当成分,为关系代词,而在同位语从句中不作任何成分,仅起连词作用。如:The fact that we talked about is very important.我们讨论的情况非常重要。(定语从句)The fact ...
怎么区分定语从句,谓语从句,同位语从句
没有谓语从句的。定语从句就是修饰前半部分的内容,有关系代词 who that which whom 和 关系副词 when why where引导。跟小明讲话那位是我语文老师。The person who\/that is talking with XIAOMING is my chinese teacher.就举一例,其余去看语法书。这句话中关系代词用who和that都行,who that在...
怎么区分同为语从句与定语从句
excited,但是看从句,that he told us,that 后的句子“he told us" he 是主语,told是谓语,us是间接宾语(tell sb sth=tell sth to sb),那那个sth是谁充当的呢,就只能是前面的引导词that了,因此that在从句中做的是told的直接宾语,做了成分,那这个从句自然是定语从句了。这回明白了么 ...
补语从句和定语从句的区别
补语从句和定语从句的区别主要体现在以下几个方面:作用不同:定语是用来修饰、限定、说明名词或代词的品质与特征的,其作用是限制和描写。限制作用体现在范围的缩小,描写作用体现在使描述对象更加生动形象。补语是述补结构中补充说明述语的结果、程度、趋向、可能、状态、数量等的成分,其与述语之间是补充...

现在简单介绍一下宾语从句和定语从句:1 宾语从句顾名思义,就是做宾语的句子,例如(1):I think (that) you are a good student.这里(that) you are a good student是think的宾语;例如(2): I don't know how I can get there.这里how I can get there是know的宾语。2 所谓定语从句,你...

涉县19336944381: 主语从句和定句从句的区别 - ?
庞阅灭菌: 主语的是用一个句子代替主语作成分而定语是一种修饰非必需成分所以作题时重在分清句子成分看看作为主系表或主谓宾的基本成分是否完整缺就用相应名词性从句否则就定状之类从句
涉县19336944381: 怎么样区别定语从句和主语从句啊? - ?
庞阅灭菌: 简单的说,你可以把整个从句括起来,将他作为一个整体.然后看这个整体在句子里面扮演什么角色.该整体作主语,则是主语从句.作定语,是修饰成分则是定语从句.其他从句亦然.还可以将从句的作用来判断.如果是主语从句,那么该从句去掉句子就不成立了.如果去掉不影响句子的结构.主谓宾全齐,只是少了个修饰成分,那么这个是定语从句.祝学习进步!

庞阅灭菌: 首先要明白主语从句和定语从句都是复合句的一种形式.两者的区别在于定语从句是一个修饰名词或代词的主谓结构,而主与从句则是用一个完整的主谓结构来做另一个主谓结构的主语! 上面的那个人的答案完全错误阿 !
涉县19336944381: 请问:怎样判断定语从句、主语从句和表语从句请说的通俗易懂点. - ?
庞阅灭菌:[答案] 1.主语从句是一个从句作主语 比如:Where a person comes from will affect their style of speech. 由that,which,whether,where,what,how,when,why,and so on引导的从句做主语,就是主语从句 2.当从句在表语的位置时,就是表语从句 比如/:That is why ...
涉县19336944381: 定语从句和主语从句的区别 - ?
庞阅灭菌: 定语是修饰名词的,把定语去掉也是一个结构完整的句子 这里如果把从句去掉就没有主语了,所以从句不是定语从句,是主语从句 定语从句和主语从句内部都缺一个成分 What能引导主语从句,不能引导定语从句
涉县19336944381: 英语中定语从句和主语从句的区别? - ?
庞阅灭菌: 定语从句 是由关系代词或关系副词引导的从句,其作用是作定语修饰主句的某个名词性成分,相当于形容词,所以又称为形容词性从句,一般跟在它所修饰的先行词后面.在复合句中,修饰某一名词或代词叫做定语从句.主语从句(Subject Clause) 在复合句中充当主语成分的句子叫做主语从句.
涉县19336944381: 请问如何判断定语从句和主语从句??
庞阅灭菌: 首先主语从句是名词性从句中的一种,名从包括主从,宾从,表从和同位语从句.那么判定定语从句和名从的条件是:看主句完整与否,如果主句完整,那么是定从或者同从(北京不考),如果主句不完整,就是主,宾,表从句.所以在做从句题时,首先必须判定从句类型.新东方中小学一对一在英语学习技巧方面很有经验,可以请教相关的老师.
涉县19336944381: 怎样区分定语从句和主语从句??
庞阅灭菌: 定语中的关系副词,关系代词都会做成分,去掉它句子不完整,且关系代词和关系副词都用于句中,主语从句多用what.that 等引导,多放在句首,最简单的办法就是看它们的位置,这是我个人的经验
