高中定语从句详细讲解(精彩3篇)
高中定语从句详细讲解 篇一
定语从句是英语语法中的一个重要部分，它在句子中起到修饰名词或代词的作用。在高中英语学习中，定语从句是一个需要重点掌握的知识点。本篇文章将详细讲解高中定语从句的基本概念、用法和注意事项。
一、基本概念
定语从句是由关系代词或关系副词引导的从句，在句中作为定语修饰先行词。关系代词包括that, which, who, whom, whose等，关系副词包括where, when, why等。定语从句通常紧跟在先行词之后，并且不能单独成句。
二、用法
1. 限制性定语从句：它对先行词进行修饰，不可省略，去掉会导致句子意思不完整或不明确。
例如：The book that I borrowed from the library is very interesting.
我从图书馆借的那本书非常有趣。
2. 非限制性定语从句：它对先行词进行补充说明，可省略，去掉不会影响句子的基本意思。
例如：My sister, who is a doctor, works at the local hospital.
我的姐姐是一名医生，她在当地的医院工作。
三、关系代词的选择
1. who和whom用于人，who作主语，whom作宾语。
2. which用于物，作主语或宾语。
3. that既可以用于人也可以用于物，作主语或宾语。
4. whose表示所有关系，用于人或物。
四、注意事项
1. 当先行词是不定代词时，关系代词的选择要根据其指代的内容来决定。
例如：I have something that I want to show you.
我有一些东西想要给你看。
2. 当先行词是表示时间或地点的名词时，应使用关系副词where或when引导定语从句。
例如：This is the school where I studied three years ago.
这是我三年前上学的那所学校。
3. 当先行词被修饰的成分在定语从句中充当主语时，常常使用关系代词that或who。
例如：The person that/who called you just now is my teacher.
刚才给你打电话的那个人是我的老师。
综上所述，高中定语从句是一个需要重点掌握的知识点。通过理解定语从句的基本概念、用法和注意事项，我们可以更准确地使用它，并且能够在写作和阅读中更好地理解句子的意思。希望本篇文章对你的学习有所帮助。
高中定语从句详细讲解 篇二
定语从句是英语语法中的一个重要部分，它在句子中起到修饰名词或代词的作用。在高中英语学习中，定语从句是一个需要重点掌握的知识点。本篇文章将继续讲解高中定语从句的用法，包括定语从句的位置和引导词的省略。
一、定语从句的位置
定语从句通常紧跟在先行词之后，修饰先行词。然而，在某些情况下，我们也可以将定语从句放在句子的其他位置。
1. 先行词位于定语从句之后的情况：
例如：I have three sisters, all of whom are doctors.
我有三个姐姐，她们都是医生。
2. 先行词位于定语从句之前的情况：
例如：The book I borrowed from the library is very interesting.
我从图书馆借的那本书非常有趣。
二、引导词的省略
在定语从句中，有时我们可以省略引导词，这样可以使句子更加简洁，但省略引导词要遵循一定的规则。
1. 当定语从句中的先行词是人，并且在定语从句中作主语时，我们可以省略关系代词who或that。
例如：The man (who/that) I met yesterday is my uncle.
我昨天遇到的那个人是我的叔叔。
2. 当定语从句中的先行词是物，并且在定语从句中作主语时，我们可以省略关系代词which或that。
例如：The car (which/that) I bought last month is very expensive.
我上个月买的那辆车非常贵。
3. 当定语从句中的先行词是人或物，并且在定语从句中作宾语时，我们可以省略关系代词who, whom, which或that。
例如：He is the person (who/whom/which/that) I talked to yesterday.
他是我昨天和他交谈的人。
通过学习定语从句的用法和位置，以及引导词的省略规则，我们可以更灵活地运用定语从句，使句子更加简洁明了。希望本篇文章对你的学习有所帮助。
高中定语从句详细讲解 篇三
一.基本概念
1.定语从句的定义：用作定语的从句叫定语从句。
2.先行词：被定语从句所修饰的名词或代词。
3.定语从句的位置：紧跟先行词(名词或代词)之后。
4.引导词：引导定语从句的词(包括关系代词和关系副词)。
﹙1﹚关系代词：that/who/whom/which/as
﹙2﹚关系副词：when/where/why
5.引导词的位置：位于定语从句之前(先行词之后)。【as除外】
6.引导词的功能(作用)：
﹙1﹚连接先行词和定语从句。
﹙2﹚在定语从句中充当一定的成分(关系代词充当主语或宾语，关系副词充当状语)。
7.定语从句的类型：
﹙1﹚限定性定语从句(主句和定语从句之间无逗号)。
① 直接由引导词引导定语从句
The man who you’re talking to is my friend.
② 由介词+关系代词(whom/which)引导
The man to whom you’re talking is my friend.
I need a pen with which I can write a letter.
=I need a piece of paper on which I can write a letter.
介词的选用可根据从句中的`相关词组确定，该介词通常可以放在关系代词之前，也可放在从句之尾。例如：
The man (who/whom/that) I talked about at the meeting is from Beijing University.
=The man about whom I talked at the meeting is from Beijing University.
The palace (which/that) I often pay a visit to was built in the 17th century.
=The palace to which I often pay a visit was built in the 17th century.
﹙2﹚非限定性定语从句(主句和定语从句之间用逗号隔开)。
① 直接由引导词引导定语从句。
② 由介词+关系代词(whom/which)引导。
I live in a house far away from the city, in front of which is a big tree.
There is an apple tree standing at the gate, on which are many apples.
This is the man to whom I gave the book.
③ 由“代词/名词+of+whom/which”或“of which/ whom +名词/代词”(先行词指
人用whom,指物用which)引导。One, some, any, none, all, both, several, many, most, neither, either等词、数词、分数或百分比与of whom或of which连用。
He has five children, two of whom are abroad.
(比较：He has five children, and two of them are abroad.)
We have three books, none of which is/are interesting.
(比较：We have three books, but none of them is/are interesting.)
除why和that不能引导非限定性定语从句外，其余引导词都可以，用法同限定性定语从句一样。但要注意以下区别。
1.在形式上非限定性定语从句与主句有逗号隔开。
2.非限定性定语从句的作用：它只是补充说明先行词的情况，翻译时可译成两个句子。
The engineer, whose leg was badly hurt, was quickly sent to hospital.
(那位工程师被很快送往医院，其腿部受了重伤)
The engineer whose leg was badly hurt was quickly sent to hospital.
(那位腿部受了重伤的工程师被很快送往医院)
3.在非限定性定语从句中，任何引导词都不能省略(包括引导词在此定语从句中充当宾语在内)。指人做主语时只能用who, 做宾语时用whom;
指物做主语，宾语都用which; 关系副词用when或where,也不能省略。
The man, ______ is sitting on the chair, is my father.
The woman, _______ I met yesterday, is my English teacher.
The city, _______ is far away, is very beautiful.
He went to America, ______ his parents live.
He joined the Army yesterday, ______ I left, too.
4.whose引导非限定性定语从句：
The house, whose window faces south, is mine.
=The house, the window of which faces south, is mine.
=The house, of which the window faces south, is mine.
二。定语从句中关系代词和关系副词的基本用法。
1.who/that指人是主格在定语从句中代替先行词，又作定语从句的主语，不能省略。
Do you know the gentleman who/that is sitting there?
2.whom/who/that指人是宾格，在定语从句中代替先行词，又作定语从句的宾语(动宾或介宾)。
① 当作动宾(动词后接宾语)时，关系代词可省略。
Do you know the gentleman (whom/who/that) we met just now?
② 当作介宾(介词后接宾语)时：
介词不提前时，关系代词可省略;
介词提前时，关系代词不可省，即介词+whom(指人时介词后的关系代词只能用whom)。
The man (whom/who/that) I spoke with is my teacher.
The man with whom I spoke is my teacher.
※注：固定的动词短语(动词+介词)如look for, take care of等不能把动词与介词拆开，既介词不能提至引导词前。
She is the right girl (who/whom/that) we are looking for.
3.whose: 指人或物，是所有格“…的”形式。Whose+n.一起在定语从句中充当主语、宾语(动宾或介宾)即先行词的什么
东西怎样
了，whose不能省略。Whose+n. = the +n. + of which/whom= of which/ whom+ the =n.
I didn’t find the desk whose leg was broken. (主语)
He is the student whose pencil I broke yesterday. (动宾)
The boss in whose company I work is very kind. (介宾)
4.which/that 指物，指代先行词且在定语从句中作主语或宾语(动宾或介宾)。
① 当作动宾时，关系代词可省略。
② 当作介宾时：
介词不提前时，关系代词可省略;
介词提前时，关系代词不可省，即介词+which(指物时介词后的关系代词只能用which)。
The house which/that was destroyed in the earthquake is weak.
The pen (which/that) you found yesterday is mine.
The games (that/which) the young men competed in were difficult.
The games in which the young men competed were difficult.
※注：介词+关系代词即介词+whom/which(先行词指人用whom,指物用which)。
※5.as指人或物，在定语从句中可作主语，宾语，表语或状语，不能省略。主要用于 “the same …as…;such …as…;so …as…;as … as…;as follows”固定结构中，形式固定此时的引导限定性定语从句。要用as代替who(m), which, 或that引导定语从句：
Such people as knew Hill thought he was honest.
Such people as Hill knew thought he was honest.
My hometown is no longer the same as it was.
Here is so big a stone as no one can lift.
The child knows as much as grow-ups (know).
I’d like to have the same books as are used in your school.
He is not such a person as I expected.
He will marry as pretty a girl as he can find.
※注：which和as可引导非限定性定语从句：可以指代主句中的一部分或整个句子的内容，which和as都可以指代主句中的一部分或整个句子的内容，有时可以互换。因此，当as/which指代前面的整个句子，或前句中的部分内容作定语从句的主语时，谓语用单数。
Our team lost the game, as/which was reported in the newspaper.
She was terrified, as/which I could see from her eyes.
He married her, as/which was natural.
区别：
①as引导的非限制性定语从句可以放在主句前面、插在主句中间或放在主句末尾;而which引导的非限制性定语从句只能放在主句后面。
He married her, as/which was natural.
=As was natural, he married her.
Mark Twin is a great writer, which/as is known to all.
=As is known to all, Mark Twin is a great writer.
②as引导的从句有“正如”、“正像”之意，而which则无此意。常用句型有：
as we all know, as is known to all, as everybody can see, as is expected, As is known/ said/ reported/ told/ we all know等。如：
As we all know, paper was first made in China.
To shut your eyes to facts, as many of you do, is foolish.
③主句和从句有因果关系时，用which
.
Our class has won the football match, which made us very happy.
Bamboos are hollow, which makes them very light.
④从句含否定意义时常用which.
She didn’t pass the exam, which we couldn’t expect.
She didn’t pass the exam, as we expected.
6.when关系副词：指时间。在定语从句中作时间状语，不能省略。此时的when还可用介词+which替换(此时先行词一定是表时间的名词)。
I still remember the time when I joined the League.
=I still remember the time on which I joined the League.
=I still remember the time (which/that) I joined the League on.
7.where关系副词：指地点。在定语从句中作地点状语，不能省略。此时的when还可用介词+which替换(此时先行词一定是表地点的名词)。
I still remember the school where I joined the League.
=I still remember the school in which I joined the League.
=I still remember the school (which/that) I joined the League in.
※注：对关系副词when, where的认识。
①. 先行词是时间的名词，并非都用关系副词when引导定语从句。
I’ll never forget the time (which/that) I spent in Beijing.
②. 先行词是地点的名词，并非都用关系副词where引导定语从句。
This is the factory (which/that) he visited yesterday.
③. 当句型为It/This/That is(was) the first(second…last) time引起的句子时用that连接其后的句子。此时的time是次数，不是时间。
It/This is the first time that we travel.
It/This is the last time that I shall give you a lesson.
8. why指原因，在定语从句中作原因状语，先行词通常为reason,不能省略。且why引导的定语从句只能是限定性定语从句。Why= for which
I don’t know the reason why he was late yesterday.
The reason why(for which) he was late is that he missed the bus.
※注：当先行词为reason时，关系副词并非都用why.
This is the reason (that/ which) he gave/ explained to us.
