定语从句（2）难点分析

限制性定语从句只能用that的几种情况

(1)Can you remember the scientist and his theory that we have learned?

你能记住我们学过的科学家和他的理论吗？

由that引导的定语从句中，that可以指人或物，在从句中作主语或谓语动词的宾语，但不能放在介词后面作介词宾语。

如：The book that I bought yesterday was written by Lu Xun.

注意在下面几种情况下必须用that引导定语从句：

(1)先行词是不定代词all, few, little, much, something, nothing, anything等，如：All that we have to do is to practice English.我们所要做的就是练习英语。

(2)先行词被序数词或形容词最高级所修饰，如：The first letter that I got from him will be kept.第一封他给我写的信会被保存下来。

(3)先行词被all, any, every, each, few, little, no, some等修饰，如：I’ve eaten up all the food that you gave me.我已经把你给我的所有食物吃光了。

(4)先行词被the only, the very, the same, the last修饰时，如：He is the only person that I want to talk with.他是唯一一个我想和他说话的人。

(5)先行词既有人又有物时，如：They talked about persons and things that they met.他们谈论了所见的人和事物。

(6)当句中已有who或者which时，为避免重复，如：Who is the man that is giving us the class? 谁将是给我们上课的人？

(7)在there + be 的句型中，句子的主语是先行词，而且又是物，如：There are two novels that I want to read.这有两本我想读的小说。

There is no work that can be done now.没有什么工作现在能做的了。

(8)当先行词为主句的表语或者关系代词为从句的表语时，如：This is the book that was bought yesterday.这就是昨天买的书。

Our school is no longer the school that it used to be.我们的学校不再是以前的学校了。

(9)以Here is(are)开头的句子时，如：Here is a film that will move anyone.这是一部将使所有人感动的电影。

Here are two books that I will buy.这是我要买的两本书。

(10)It is(high)time +定语从句，如：It is time that we should have a rest.我们应该休息了。

It is high time that they started out.他们该动身了。

只用which的场合如下：

1)非限制性定语从句中

Last night, I saw a very good film, which was about the Long March.昨天晚上，我看了一部好电影，是一部关于长征的电影。

2）介词放在关系代词之前时 This is my house of which the roof is red.这个房子屋顶是红色的。

3）句中出现了that，或先行词是that时

I have found that which I was looking for.我已经找到了我一直寻觅的东西。

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.同位语从句

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.定语

(2)The news that he has just died is true.同位

(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.同位

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.(4)The fact is that the earth moves around the earth.限制性定语从句和非限制性定语从句非限制性定语从

(1)限制性定语从句是句中不可缺少的组成部分，主句和从句之间不用逗号分开。引导

句的关系代词有who, whom, whose, which, of which等，这些关系代词都不能省略。

(2)非限制性定语从句是对主句先行词的补充说明，没有这种从句，不影响主句意思的完整，一般用逗

号把主句和从句分开，关系代词用which，不用that；指人时可用who。

如：I have two brothers，who are both students.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.当先行词受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：当先行词由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.她穿着她在玛丽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。

非限定性定语从句几个注意的地方

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.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).2.as可引导非限制性从句，常带有“正如”。

1）As we know, smoking is harmful to one's health.2）As is known, smoking is harmful to one's health.as是关系代词。1中的as作know的宾语；

2中，它充当从句的主语，谓语动词know要用被动式。

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。

e.g.The way in which/ that/不填 he answered the question was surprising.他回答问题的方式很惊人。

but有时也可以做关系词引导定语从句

e.g.There are very few but understand his idea.(but = who don’t)

没有几个不懂他意思的人。

定语从句

I 概念

定语从句通常是指用来修饰或限制某一名词或代词的从句，其作用相当于形容词。1.先行词：被定语从句所修饰和限制的名词或代词称之为先行词。2.关系词：引导定语从句的词。

关系代词

that, which, who, whom, whose, as, but, than 关系词

关系副词 when, where, why 解题思路：找先行词，看先行词在定语从句中充当何种成分，然后确定用何种关系词。He still lives in the house ______is in the north of the city.He still lives in the house ______window faces to the south.He still lives in the house ____there is a piece of furniture.(先行词分别在定语从句中作主语、定语、地点状语。因此分别用which/that;whose;where.)I’ll never forget the days ______we spent together.I’ll never forget the days ______we stayed together.(先行词the days分别在定语从句中作宾语、时间状语。因此分别用which/that;in which/ when.)The reason ______he gave us was reasonable.The reason ______he didn’t attend the meeting was that he was ill.(先行词the reason分别在定语从句中作宾语、原因状语。因此分别用which/that;why.)This is the only way ______you can find.I didn’t like the way _____he spoke to his mother.(先行词分别在定语从句中作宾语、方式状语。因此分别用that或省略；in which/that或省略)那么该如何确定关系词呢？首先看在限制性定语从句中： 一 当先行词在定语从句中作主语、宾语或表语/宾补时：

主语

宾语

1.先行词指人，在定语从句中作主语时，一般用who或that都可以。但在下列情况下，通常用who，而不用that。

1)当先行词是people, those, one/ones, anyone/anybody等时

People who can see sometimes act just as foolishly.Those who were either fools or unfit for their offices could not see the cloth.

5)一个句子带有两个定语从句，一个用who，另一个用that.The student who was praised at the meeting is the monitor that is very modest and studies very hard.在会上受到表扬的那个学生是班长，他谦虚好学 2.在下列情况下,通常用that,而不用who 1)先行词前面有the first, the last, the only或the same等所修饰时 She is the last man(that)I want to see.她是我最不愿意见到的人

She is the only person that understands me.She is the same teacher that was praised the other day.2)主句是以who或which开头的特殊疑问句时

Who that has common sense will do such a thing? Which one of us that knows something about physics does not know this? 3.先行词是物，在定语从句中作主语或宾语时，一般用which或that都可以。但在下列情况下, 通常用that，而不用which.。

6.注意下列两种句式的定语从句： 1)It is(high/about)time(that)„过去式

2)It/This/That is/will be the first/second/third„time(that)„

从句的时态用现在完成时 It/This/That was the first/second/third„time(that)„

从句的时态用过去完成时 It is time we went to bed It is the first time that he has come to meet me at the station.It will be the second time that I have been there.It was the first time that he had passed the examination in English.7.注意避免出现以下几种情况：

1)The storybook(which/that)I have just read it cannot be easily forgotten.定语从句中不可使用与关系词意义相重复的词。应删除it，因为it与关系代词which/that在意义相重复。

2)Her two daughters who are studying in Beijing.缺少谓语动词，应去掉who，改为Her two daughters are studying in Beijing.3)Prices of daily goods are bought through a computer can be lower than store prices.两个谓语动词，缺少连接词。改为Prices of daily goods(which are)bought through a computer can be lower than store prices.4)Is this museum they visited last week? 缺少表语，加上the one 使句子成立。改为Is this museum the one they visited last week? /Is this the museum they visited last week? 5)We all like Harry because he is a man whom everybody thinks is pleasant to get along with.将whom改为who.everybody thinks是插入语。

介词+whom(人)、which(物)

定语从句教案

1．这一结构用什么关系词取决于先行词的指代.指人用whom,指物用which..注意不能用who或that,也不能省略.用什么介词取决于定语从句中谓语动词结构及“介词+whom/which”在句中的作用.He is the man for whom my sister bought a gift.(先行词指人,用whom, 谓语动词是buy sth.for sb.这一习惯搭配.故用for whom)The two things of/about which Marx was not sure were the grammar and some of the idioms of English.(先行词指物，用which.谓语动词是be sure of /about这一习惯搭配.故用of/about which)2.这一结构中的介词的位置比较灵活.但是“动词+介词”构成的短语动词一般不拆开.The person(who/whom/that)you should write to is Mr.Ball.=The person to whom you should write is Mr.Ball.Nearby were two canoes(which /that)they had come to the island in.=Nearby were two canoes in which they had come to the island.The babies(who/whom/that)the nurses are looking after are very healthy.Is this the book(which/that)she was looking for? 3.where 和when有时用作关系代词相当于which point/place和which time用来充当定语从句中介词的宾语

一般说来，定语从句是紧跟在先行词后面作先行词的定语，但有时出于平衡句子结构或强调某个成份的需要而将定语从句与先行词分隔开来。这样的从句称为分隔定语从句。I was the only person in my office who was invited.(被状语分隔)Do you remember one afternoon ten years ago when I came to your house and borrowed a diamond necklace? But the Southern states wanted to set up a country of their own, where they would be free to keep black slaves.(被定语分隔)What have I said that makes you so angry? 我说了什么，把你气成这个样子？

在„„the(only/very)one of„„who/that„„的结构中，先行词是the(only/very)one,定语从句中的谓语动词用单数形式

He is one of the students in our class who were praised by the headmaster yesterday.他是我班昨天受到校长表扬的学生中的一个

He is the only one of the students in our class who was praised by the headmaster yesterday.他就是我班昨天唯一受到校长表扬的那个学生 六.定语从句和其他结构的区别 1.定语从句与分词

Was it on the day that you joined the army? 如果It is/was„的后面接的是名词词组，一般是定语从句。如果It is/was„的后面接的是副词、介词短语，一般是强调句型。4.定语从句与主语从句

定语从句教案

2)介词后面的宾语从句

This is the way(in which/that)the whole city is fed.=This is how the whole city is fed.7.定语从句与同位语从句的区别

We heard the news which/that had spread quickly.We heard the news that our team had won.引导定语从句的关系词，在定语从句中必须充当句子的成分。

引导同位语从句的that，在同位语从句只起连接作用，不充当句子的成分。that不能省略，也不能用which来代替。8.定语从句与结果状语从句
