定语从句知识总结2

一、as引导定语从句

as引导定语从句时,既可以引导限定性定语从句,又可以引导非限定性定语从句。区分as引导定语从句和其它从句的关键特征是:as引导定语从句时在从句中做成分,通常做主语或宾语。

1、as引导限定性定语从句

如从句所修饰的名词前有such、the same、as出现,后面的定语从句将由as引导,形成such...as,the same...as,as…as这样的固定结构,译为“和……一样”。

例1:I never heard such stories as he told.

我从未听过他所讲的那样的故事。

例2:He’ll repeat such questions as are discussed in the book.

他将重复书中讨论过的问题。

例3:They made the same mistake as others would have made on such an occasion.

他们犯了和其他人在这种场合下会犯的同样错误as用法详解as用法详解。

2、as引导非限定性定语从句

as引导非限定性定语从句,往往指代一整句话,通常表示“正如”的意思。as引导的非限制性定语从句位置相对比较灵活,可以位于先行词之前、之后或中间。

例:As is known to everybody, the moon travels round the earth.

众所周知,月亮绕着地球转。

二、as引导时间状语从句

as引导时间状语从句多用于口语,强调“同一时间”或“一先一后”,有时还有“随着”的含义。

例1:As I was going out, it began to rain.

当我出门时,开始下雨了。(as强调两个动作紧接着发生,不强调下雨的特定时间。)

例2:As time goes on, he will understand what I said.

随着时间的推移,他会理解我所讲的话。

三、as引导原因状语从句

as表示“因为”,与because相比,较口语化,所表达的原因语气较弱,所表的原因比较明显,或是已知的事实。

例1:As the weather is so bad, we have to delay our journey.

因为天气太糟糕,我们不得不推迟旅行。

例2:Any new source of energy will be very welcome, as there is already a shortage of petroleum.

任何新型能源都将大受欢迎,因为石油已经出现短缺。

四、as引导方式状语从句

as表示“按照”,“以……方式”,“像……一样”,“正如”。

例:Do as the Romans do when in Rome. 入乡随俗

注:as在引导方式状语从句时,还常出现在一个固定的类比结构中:(just) as …, so…。这一句型表示类比,基本含义是“正如……,所以……”。

例:Just as virtue is its own reward, so is vice its own punishment.

善有善报,恶有恶报。

五、as引导让步状语从句

as可以表示“尽管”,“虽然”,引导让步状语从句,但必须构成倒装。让步状语从句倒装规则有两类:

1、形容词/副词/分词/名词(无冠词)/介词短语等+as+主语+谓语动词,主句。

例1:Much as I like you, I couldn’t live with you.

我尽管很喜欢你,却不能和你在一起生活。

例2:Child as he is, he knows to help others.

尽管他是个孩子,他懂得帮助别人。

2、动词原形+as+主语+助动词(may/might, will/would, can/could, do/does/did),主句as用法详解考研英语。

例:Try as we may, we cannot sense directly the television signal sent out from the broadcast station.

尽管我们费了很大的劲,也无法直接觉察发射台发出的电视信号

六、as引导比较状语从句

as引导比较状语从句,其基本结构是as…as。前一个as是副词,后一个as是比较状语从句的连词。否定结构为not so much … as …。

例1:Small as it is, the ant is as much a creature as are all other animals on the earth.

尽管蚂蚁很小,但是它同地球上的任何其他动物一样,也是一种动物。

例2:It was not so much the many blows he received as the lack of fighting spirit that led to his losing the game.

与其说是他受到了许多打击,还不如说是缺乏斗志使他输掉了比赛。

定语从句知识总结3

(一)定语从句一般由关系代词和关系副词引导

1、关系代词:who, whom, whose, which, that, as

2、关系副词:when, where, why

关系代词和关系副词必须位于从句之首,主句先行词之后,起着连接先行词和从句的作用, 同时在从句中又充当句子成分,高考语法复习四:定语从句。

She is the girl who sings best of all.(关系代词who在从句中作主语)

The comrade with whom I came knows French.(whom在从句中作介词with的宾语)

3、关系代词和关系副词的用法:

1)当先行词为人时用who 作主语,whom作宾语;

2)当先行词为物或整个句子时用which ,可作主语或宾语;

3)先行词为人、物时用that ,可作主语或宾语;

4)whose用作定语,可指人或物;

5)关系副词when(指时间,在定语从句中作时间状语,where(指地点,在定语从句中作地点状语),why(指原因,在定语从句中作原因状语)。

(二)限制性定语从句与非限制性定语从句

1、限制性定语从句:从句与主句关系密切,去掉从句,主句意义不完整,甚至不合逻辑。

I was the only person in our office who was invited.(去掉定语从句,意思就不完整)

2、非限制性定语从句:从句对先行词关系不密切,去掉定从句,意思仍然完整。形式上用逗号隔开,不能that用引导。

Tom's father, who is over sixty, still works hard day and night.(who引导非限制性定语从句,整个句子可分成两句来翻译)

(三)使用定语从句时特别注意的几个问题

1、that与which的区别。

1)用that而不用 which的情况:

①先行词为不定代词all, anything, nothing, …;

②先行词有最高级修饰,有序数词修饰;

③先行词有only, very, any等词修饰;

④先行词既有人又有物时。

There is nothing that can prevent him from doing it. 没有什么能阻止他不干那件事。

The first place that they visited in Guilin was Elephant Trunk Hill. 在桂林他们所参观的第一个地方是象鼻山。

This is the best film that I have ever seen. 这部电影是我看过的最好的一部。

Mr Smith is the only foreigner that he knows. 史密斯先生是他认识的唯一的外国人。

2)用which而不用 that的情况:①引导非限制性定语从句;②代表整个主句的意思;③介词 + 关系代词。

He had failed in the maths exam, which made his father very angry. 他数学考试没有及格,这使他的父亲很生气。

This is the room in which my father lived last year. 这是父亲去年居住过的房子。

3)as引导定语从句时的用法

①as引导限制性定语从句通常用于the same … as, such … as结构中。

I want the same shirt as my friend's. 我要一件跟我朋友一样的衬衫。

Such machines as are used in our workshop are made in China. 我们车间使用的这种机器是中国制造的。

②as引导非限制性定语从句既可放在主句之前,也可放在主句之后,用来修饰整个句子。通常用下列句型:as is known to all, as is said, as is reported, as is announced, as we all know, as I expect 等。

As I expected, he got the first place again in this mid-term examination. 正如我所预料的那样,他在这次期中考试中又获得了第一名。

3)as 引导非限制性定语从句时与which的区别

①当主句和从句语义一致时,用as;反之,用which来引导非限制性定语从句。

He made a long speech, as we expected.

He made a long speech, which was unexpected.

②当非限制定语从句为否定时,常用which引导。

Tom drinks a lot every day, which his wife doesn't like at all.

2. 关系代词在从句中作主语时,从句的谓语动词单数还是用复数应由先行词决定。

The man who lives downstairs speaks English fluently. 住在楼下的那个人英语说得很流利。

The students who are in Grade Three are going to climb the hill tomorrow.

3. 定语从句有时不直接紧靠先行词,中间由一个定语、状语或谓语隔开。

There is an expression in his eyes that I can't understand.

4. 引导定语从句的关系副词有时可以用"介词 + which"来代替,英语语法《高考语法复习四:定语从句》。

October 1, 1949 was the day on which ( = when ) the People's Republic of China was founded.

5. 当定语从句中谓语动词是带介词或副词的固定短语动词时,短语动词的各个固定部分不要拆开。

The sick man whom she is looking after is her father.

6. 介词在关系代词前,只能用which和whom,且不能省略;介词在句尾,关系代词可有which, that, whom, 口语中也可用who,且可省略。

The man (whom/ who/ that) you were talking about has come to school.

定语从句知识总结4

一、定语从句的概念

在复合句中,修饰某一名词或代词的从句叫定语从句。被修饰的名词或代词叫先行词,定语从句一般放在先行词的后面。

二、定语从句的关系词

引导定语从句的关系词有关系代词和关系副词,常见的关系代词包括that, which, who(宾格whom,所有格whose)等,关系副词包括where, when, why等。关系代词和关系副词放在先行词及定语从句之间起连接作用,同时又作定语从句的重要成分。

三、定语从句的分类

根据定语从句与先行词的关系,定语从句可分为限制性定语从句及非限制性定语从句。限制性定语从句紧跟先行词,主句与从句不用逗号分开,从句不可省去,非限制性定语从句主句与从句之间有逗号分开,起补充说明作用,如省去,意思仍完整。

四、关系代词的用法

1. that 既可以用于指人,也可以用于指物。在从句中作主语或宾语,作主语时不可省略,作宾语可省略。例如:

Mary likes music that is quiet and gentle.玛丽喜欢轻柔的音乐。(that作主语)

The coat (that) I put on the desk is blue.我放在桌子上的那件外套是蓝色的。(that作宾语)

用于指物,在句中作主语或宾语,作主语不可省略,作宾语可省略。例如:

The building which stands near the train station is a supermarket.位于火车站附近的那座大楼是一家超市。(作主语)

The film (which) we saw last night was wonderful. 我们昨天晚上看的那部电影很好看。(作宾语)

, whom用于指人,who 用作主语,whom用作宾语。在口语中,有时可用who代替whom,也可省略。例如:

The girl who often helps me with my English is from England.经常在英语方面帮助我的那个女孩是英国人。(作主语)

Who is the teacher (whom) Li Ming is talking to?正在与李明谈话的老师是谁?(作宾语)

注意:

(1)当定语从句中含有介词,介词放在句末时,who, that, which可省略,但介词在关系代词前时,只能用“介词+which/whom”结构。例如:

This is the house in which we lived last year.这是我们去年居住的房子。

Please tell me from whom you borrowed the English novel.请告诉我你从谁那借的这本英文小说。

(2)含有介词的固定动词词组中,介词不可前置,只能放在原来的位置上。例如:

This is the person whom you are looking for. 这就是你要找的那个人。

(3)that 作介词的宾语时,介词不能放它的前面,只能放在从句中动词的后面。例如:

The city that she lives in is very far away.她居住的城市非常远。

(4)关系词只能用that的情况:

a. 先行词被序数词或形容词最高级所修饰,或本身是序数词、基数词、形容词最高级时,只能用that,而不用which.例如:

d. 先行词里同时含有人或物时,只能用that, 而不用which.例如:

I can remember well the persons and some pictures that I saw in the room.我能清楚记得我在那个房间所见到的人和一些照片。

e.以who或which引导的特殊疑问句,为避免重复,只能用that.例如:

Who is the girl that is crying? 正在哭泣的那个女孩是谁?

f.主句是there be 结构,修饰主语的定语从句用that,而不用which.例如:

There is a book on the desk that belongs to Tom. 桌子上那本书是汤姆的。

(5)关系词只能用which,而不用that 的情况:

a.先行词为that, those时,用which, 而不用that.例如:

What’s that which is under the desk? 在桌子底下的那些东西是什么?

b.关系代词前有介词时,一般用which,而不用that.例如:

This is the room in which he lives. 这是他居住的房间。

c.引导非限制性定语从句,用which, 而不用that.例如:
