As 引导定语从句扫描

在定语从句中,一般的从句关系代词是which、who、whom、that、whose, 其代替主句中的人或物,在从句中做主语、宾语或定语。而学生在学习过程中,常会遇到as作为关系代词出现,做起题来,无从下手,就此笔者对as作为关系代词引导定语从句的情况做一归纳, 以供参考.

一、as引导限制性定语从句

主要结构有:

the same…as

as…as

such…as

so…as

主句中出现the same, as, such, so修饰先行词,需选择as做关系代词在定语从句中做主语或宾语。

1.  It’s the same person as we wanted to find yesterday .

我们昨天要找的是同一个人。

2.  Such girls as he knows are good at English .

6.  He has so difficult a problem , as none of us can solve .

他有如此难的一个问题,我们没有人能解决。

二、引导非限制性定语从句

1.  As everyone knows ,China is a beautiful country with a long history .

2.  The earth , as we know , moves round the sun .

地球,我们都知道,围着太阳转。

3.  Tom works hard and is willing to help others, as we all know.

汤母工作努力,并且乐于助人,这一点我们都知道。

⑵ 非限制性定语从句中的谓语为被动式时,常用as做主语

be said/known/announced/reported/mentioned/expected/discussed

1.       Grammar , as has been said before, is not a set of dead rules.

语法,就像以前所说,不是一套死规则。

2.       As is known to all , TaiWan is part of China .

⑶  as引导非限制性定语从句,有“如,似,正像”的含义,因此,下列句式多用as

as has been said above

如上所说

as anybody can see

正像每个人所看到的那样

as we had expected

正如我们所预料的那样

1.       Things are not always as they appear.

事情并不一直像他们表面那样。

2.       The boy has as much progress as we had expected.

正像我们所预料的那样,这个男孩取得了大的进步。

篇2:as可以引导定语从句吗

引导限制性定语从句和非限制性定语从句

(1)as多与such或the same连用,可以代替先行词是人或物的名词。

(3)the same…that与the same…as在意思上是不同的。

篇3:as引导的定语从句课件

as引导的定语从句课件

as引导非限制性定语从句,常指主句所表达的整个事情,可置句首、句中、句末。

as 作为关系代词和关系副词可以引导定语从句。

1 such……as…… “像…………一样的”,“像…………之类” the same……as…… “和…………同样的”

在这两个句型中,as 是关系代词,其中such 和same 作定语,修饰

主句里的某个名词(或代词),这个名词是as 引导的定语从句的先行词,

as 在从句中可担任主语、宾语和表语。

We have found such materials as are used in their factory.

(as 作主语)

我们找到了(像)他们厂里用的那种材料。

Such people as you describe are short nowadays. (as 在从

句中作宾语)

你描绘的这种人现在已很少了。

He is not the same man as he was. (as 在从句中作表语)

他和过去不同了。

This is the same thing as we are in need of. (as 在从句中

作宾语)

这东西和我们所需要的东西是一样的。

2 ……such as……

such 为代词,意思为“这样的人或物”,as 在从句中担任成分,修

饰先行词such。

This book is not such as I expect.(as 在从句中作宾语)

这不是一本我所希望的书。

He told me of his experience such as I had never hadbefore.

(as 在从句中作宾语)

他给我讲了他的经验,我从来没有那种经验。

I have not many, but I will send you such as I have.

我有的不多,但我愿把我所有的都送给你。

3 the same……as……

同一个…………

the same……that……

as 和that 都引导的是定语从句,所表达的意思相近或相同,但从句

中省去谓语时必须用as 代替that。

He works in the same shop as /that I do.

他和我在同一个车间干活儿。

She is the same age as you.

She is the same age that you.……(×)

她和你同年。

He uses the same books as you.

他和你用的'书是一样的。

注意

所指的是不同一个,必须另加词句。

这支钢笔就是我丢掉的那一支。 (指同一支笔)

This is the same kind (type, sort)of pen as I lost.

这支钢笔跟我丢掉的一模一样。 (但并不是原来的那一支。)

She wears the same clothes as the did last Sunday.

她穿的就是她上周日穿的那件衣服。 (同一件)

She wears the same kind of clothes as her sister does.

她穿的衣服和她姐姐(妹妹)穿的完全一样。 (但不是同一件,是同一类型)

4 ……,as ……有些

有些as 引导的定语从句已成为一些固定用法,如aswe know(正如我们所知道的)。

as 代表整个句子的内容,引导非限定性定语从句,它的先行词可以

是名词,也可以是不定式短语或整个句子,as 在从句中担任成分:主语、

宾语和表语,相当于which 引导的非限定性定语从句,有时两者可互换。

The teacher is from Beijing, as/which they know from hisaccent.

他们从老师的口语中就知道他是北京人。

As everybody can see, great changes have taken place in China.

(正如大家所能看到的)大家都看得出,中国已发生了巨大的变化。

注意

as 引导的定语从句位置灵活,可放在句首、句尾(可放在主句之前或之后)。which 引导的非限定性定语从句只能放在主句之后。

篇4: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。

that的用法:

注意:that常用作关系代词,可指代某人,也可指代某物,指物时有的时候可用which替换that,指人时可用who替换。但在下列情况下,一般用that。

that指代某物事时:

1、先行词为all, few, little, much, the one, something, anything, everything, nothing等时。

(1)We'll do all that we can to protect the endangered plants and animals.

我们将尽我们的最大努力来保护那些濒危的动植物。

(2)There is much that I wan to tell you.

(1)You can borrow any book that you want to read in our school library.

在我们图书馆,你可以借任何你想读的书。

3、先行词被序数词或形容词最高级修饰时。

这种风格的画我们仅有一幅。

They built a factory which produced things that had never been seen.

他们建了一工厂,生产以前从未见过的东西。

篇6:如何确定定语从句的引导词

如何确定定语从句的引导词

引导定语从句的关系代词有who, whom, whose, which, that; 关系副词有where, when, why。它们都在定语从句中担任句子成分。现分述如下:

1. 定语从句如果修饰人,常常用关系代词who,有时也用that(作主语时多用who)。例如:

He is a man who / that often helps others. 他是一位经常帮助别人的人。

如果这个关系代词在从句中作宾语, 就应当用whom或that, 但这种情况往往都可以把引导词省略,且在口语中可用who代替whom。例如:

Here is the man (whom / that / who) you would like to see. 这就是你想见的那个人。

值得注意的是,如果是在介词的后面就只能用whom。例如:

The boy to whom I spoke is my brother. 刚才和我说话的那个男孩是我弟弟。

如果表示“……的”时,就用who的所有格whose。例如:

Is there anyone in our class whose father is a doctor? 我们班有谁的父亲是当医生的吗?

whose的先行词也可是物。例如:

The house whose windows face the street is my uncle‘s. 窗户面朝街的那座房子是我叔叔的。

2. 定语从句如果修饰“物”,用关系代词that的时候较多,有时也用which。例如:

It‘s a computer which / that costs six thousand yuan. 这是一台价值六千元的电脑。

当这个代词在从句中用作宾语时,往往都会把它省略。例如:

The present(that / which) you gave me is very beautiful. 你给我的`那件礼物非常漂亮。

在介词的后面只能用which。例如:

This is the book about which they are talking. 这就是他们正在谈论的那本书。

3. 定语从句修饰一个表示时间的词时,用关系副词when。例如:

I will never forget the day when I met her. 我将永远不会忘记我见到她的那一天。

4. 定语从句修饰地点名词时,用关系副词where。例如:

This is the place where we lived for five years. 这就是我们曾经住过五年的地方。

5. 定语从句修饰一个表示原因的词时,用关系副词why。例如:

I know the reason why she didn‘t come yesterday. 我知道她昨天没来的原因。

篇7:高一英语教案非限制性定语从句

一、非限制性定语从句与限制性定语从句的区别     限制性定语从句,顾名思义,是对先行词从本质或特征上进行限制的一种定语从句,它所修饰的词代表一个(些)或一类特定的人或事、物。例如:     a man who doesn’t want to learn from others can’t achieve much.     一个不向别人学习的人是不能指望有多大成就的。     a man被限定后,指一类特定的人。     限制性定语从句是不能去掉的,否则剩下的部分就失去意义而不能成立。非限制性定语从句则不然,它只对所修饰的词作进一步的说明,去掉之后并不影响整个句子的含义。在形式上,非限制性定语从句与主句之间通常必须有逗号隔开。例如:     finally we visited the giant yangtze gorges dam, which is the greatest key  water control project in the world at present.     最后我们参观了长江三峡大坝,它是目前世界上最大的水利枢纽工程。     本句若去掉定语从句,主句部分的含义仍然完整。历年的高考题中,非限制性定语从句是出现频率最高的考点之一,因此值得我们注意。     二、引导非限制性定语从句的which可以指代前面的先行词,也可以指代前面整个句子。例如:     that peter will marry alice, which has not been announced yet, has spread around.        彼特要娶爱丽斯这件事还没宣布,却已被传得沸沸扬扬。     句子中的which指代“彼特要娶爱丽斯”这件事。     三、除which外,还可用when, where, who,whom等关系副词或关系代词引导非限制性定语从句。例如:     after graduation, i decided to stay in chongqing, where i spent my childhood and four years of college life.     毕业后,我决定留在重庆,在那里我度过了我的童年和四年大学生活。     albert einstein left germany for the united states during world war ii, when jews were badly treated in germany.     第二次世界大战期间,爱因斯坦离开德国去了美国,那时犹太人在德国受到极大的歧视。     注意:that不能引导非限制性定语从句。     四、在限制性定语从句中,如果先行词作宾语时,引导词可以省略;但引导非限制性定语从句的引导词不能省,同时关系代词whom不能用who替换。试比较:     the american journalist (whom / who) the announcer mentioned in the news broadcast is said to have been killed by the gangsters.     播音员在新闻广播中提到的那位美国记者据说已经被匪徒杀害了。     he was eager to go to the hospital to see his stepmother, whom he loved and respected as his own mother.     他急于想去医院看望他的继母,他像对亲生母亲一样爱戴和尊敬她。      巩固性练习:   从a、b、c、d中,选出可以填入空白处的最佳选项。     1. she heard the terrible noise, _____ brought her heart into her mouth.     a. it           b. which     c. this        d. that     2. dorothy was always speaking highly of her role in the play, ____, of course,                             made the others unhappy.      a. who      b. which     c. this        d. what     3.  the weather turned out to be very good,____ was more than we could expect.     a. what     b. which    c. that     d. it     4.  recently i bought an ancient chinese vase,____ was very reasonable.     a. which price b. the price of which       c. its price       d. the price of whose     5. the youngest nurse has worked for 30 days in the sars hospital, ____ she spent her     19th birthday.     a. that           b. which      c. where d. and     (答案bbbc)

篇8:what引导什么从句与定语从句的区别

4.不过当先行词是all的时候,定语从句通常用that引导,如果all是主句主语,那么all that两个单词可以用what代替,不过what引导的叫主语从句;如果all在主语中作宾语,刚换成what刚引导的叫宾语从句。

5.但是that和what是不可能同时引导定语从句的。

如:All that he taught me was very useful.= What he taught me was very useful.前句中的that引导定语从句,all为先行词,而后句中的.what引导的叫主语从句,what在主语从句中作taught的直接宾语。

篇10:英语中as引导的定语从句的相关讲解

as引导的定语从句

在一些习惯用法上,as能兼作关系代词、关系副词,经常引导定语从句。

惯用型1:

such… as…像……一样的

the same…as…与……同样的

I seldom meet such a beggar as I met today.

我很少碰到今天这样的乞丐。

(as是代词,在定语从句中作宾语)

Please choose such apples as can be put in my bracket.

请选择我能放入篮子里这样的苹果。

(as在定语从句中作主语)

I am not the same kind of person as you are.

我可不是和你一类的人。

(as在从句中作表语)

You may take the same bus as we take.

你可乘坐我们坐的同一辆大巴。

(as在从句中作宾语)

惯用型2:

such as…

在这种场合,such是代词,表示“这种人、这种物”,as是关系代词。

He is not such as you can imagine.

他不是你能想象得到的那种人。

We have got a lot of drinks such as you can find in supermarkets.

我们习了大量在超市能找到的那种饮料。

惯用型3:

as…

…, as…

as引导的定语从句,有时像非限制性定语从句一样修饰整个主句或者主句的一部分,但它的位置比较灵活,可以放在被修饰的主句后面,也可以放在主句前面。

例如:

As you can see, we are all students.

你能看得出,我们都是学生。

=We are allstudents, as you can see.

=We are all students, which you can see.

(这是详细的解读,大家请熟悉啊)

As you know, we need to hurry up.

大家知道,我们需要加快速度。

He is not very honest, as you have proved.

她不是很诚实,这一点你已证实了。

篇11:考研英语 which引导的定语从句

考研英语 归纳which引导的定语从句

关系代词which引导的定语从句, 指物,在从句中可以作主语、宾语等。多数情况下,可与that互换。但是要注意当从句中,介词提前只能用which,而且,在非限制性定语从句中,which引导的句子单独翻译为一句话。

(1)“The ability to guard customer data is the key to market value, which the board is responsible for on behalf of shareholders.”(-4-3)

考点:board董事会,be responsible for代表, on behalf of代表(注意在写作中的应用),shareholder股东

解析:这个句子难度为低级,划横线部分为主句只有一个难点就是which的先行词是谁,是句子还是前面的一个名词,很显然,这个句子中是指市场价值,而不是这种能力。

翻译:保护客户资料的`能力是市场价值的关键,董事会代表股东对市场价值负有责任。

难点总结:介词短语,which的先行词,非限制性定语从句一般翻译为一个单句。

(2)In Europe, as elsewhere, multi-media groups have been increasingly successful: groups which bring together television, radio, newspapers, magazines and publishing houses that work in relation to one another.(-翻译-47)

考点:multi-media 传媒集团(最好不要翻译为多媒体集团), bring together 组织,集合,work in relation to one another 彼此协作,publishing houses出版社

解析:此句难度为高级,划线部分为主句, 冒号后是主句的同位语,由which引导的定语从句来修饰groups,句尾还有that引导的定语从句来修饰television, radio, newspapers, magazines and publishing houses。As在这个句子中是副词,修饰副词elsewhere,翻译为“就像在其他地方一样”。

翻译:在欧洲,就像在其他地方一样,多媒体集团越来越成功了,这些集团把相互之间有紧密联系的电视台、电台、报纸、杂志、出版社组合到了一起。

难点总结:确认关系代词which,that的先行词(记得当先行词是两个或者两个以上的人或者物时,关系代词要用that。),as的用法。

(3)Dr. Myers and Dr. Worm argue that their work gives a correct baseline, which future management efforts must take into account.(-3-4)

考点:take into account考虑(注意要用在写作中,尤其是建议信中例如:You need to take the following factor into account when you make a decision.)

解析:这个句子难度为低级。Which在此指代的是a correct baseline。

翻译:麦尔斯博士和沃姆博士指出,他们的工作确定了一个准确的底线,未来的管理必须将其考虑进去。

难点总结:确定which的先行词。

(4)For a while it looked as though the making of semiconductors, which America had invented and which sat at the heart of the new computer age, was going to be the next casualty.

考点:semiconductor半导体,casualty伤亡,

解析:这个句子难度为高级,这个句子是主句里套从句,从句里又套从句的结构,所以分清楚主句特别重要,主句为划线部分,其中as though 引导一个方式状语从句,这个从句中又有一个由which(先行词为the making of semiconductors)引导的非限制性定语从句。

翻译:曾有一段时间,似乎半导体制造业是另一个将要覆没的产业,要知道半导体正是美国人所发明,它在计算机新时代起着核心作用。

难点总结:注意句子结构。注意各个连词的指代和意义。

篇12:who引导的定语从句五注意

作者:新华

同学们,我们都知道定语可以由形容词、代词、数词、不定式等来担任,但如果由一个句子来担任定语,那么这个句子就叫定语从句。在英语中,who可是个人气指数颇高的词,作为疑问代词,who可以引导特殊疑问句;作为关系代词,who可以引导定语从句。今天我们就一道看看who引导定语从句应注意的五个方面。

一、who引导的定语从句的先行词是表示人的名词或代词。如:

The student who is answering the question is John. 正在回答问题的那个学生是约翰。

Anybody who breaks the laws will be punished. 任何违反法律的人都将受到惩罚。

二、who是主格,在定语从句中作主语,此时不能省略。如:

The person who was here yesterday is a musician. 昨天来这儿的那个人是位音乐家。

但在非正式英语中,who亦可作宾语,且可以省略。如:

The man(who)I saw just now is Mr Li. 我刚才见到的那个人是李先生。

三、在定语从句中,who在人称、数上和其前面的先行词保持一致。如:

Do you know the boy who is standing over there? 你认识站在那边的那个男孩吗?

四、若先行词中既有人又有物,关系代词用that而不用who。如:

He watched the children and boxes that filled the car. 他看见了塞满汽车的孩子和箱子。

五、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。如:

Yao Ming is the best basketball player that I know. 姚明是我知道的最好的篮球运动员。

Tom is the first boy that left the room. 汤姆是第一个离开这个房间的男孩。

本期我们只讲解了who引导的定语从句需要注意的五个方面,以后我们还会学到其它关系代词或关系副词引导的定语从句,我们在以后的学习中会讲解的。
