大学英语语法11-定语从句
(完整版)定语从句讲解
1一、定语从句概述定语可以由形容词、名词、代词、数词、分词、副词、不定式以及介词短语 等来担任，也可以由一个句子来担任。
在句子中起定语作用的从句称为定语 从句。
定语从句在句中的作用相当于形容词，故又称为形容词性从句。
被定 语从句修饰的名词叫先行词，引导定语从句的词叫关系词。
二 关系词的用法。
关系词可分为关系代词和关系副词。
关系词指代先行词，放在先行词与 定语从句之间起连接作用，同时又充当定语从句中的某一种成分（主语、宾 语、状语等）。
引导定语从句的关系代词有"at ，who ，whom ，whose ，which;关系副词有 when ，where ，why 等。
关系词在句子中的指代作用及成分如下表 1.关系代词的用法(1) who, whom 的用法二者都用于指人。
who 在定语从句中作主语、宾语;whom 在定语从句中 作宾语。
在现代英语里，有时who 也可代替whom 在从句中作宾语。
作 宾语的关系代词who ，whom 可以省略(介词后作宾语的关系代词除外）。
She was the one who did most of the talking 。
大部分时间都是她在说话。
（作主语） The boy who I know studies best in his class.我认识的那个男孩在班上学习最好。
（作宾语）I happened to meet the professor (who/whom) I got to know at a party. 我碰巧遇见了那位在一次聚会上认识的教授。
（作宾语，whom 可用who 代替) whom 在从句中作介词的宾语，且介词提到whom 前面时，不能用who 代替。
Yesterday I came across a few friends with whom I went to the park .昨天 我碰见了几个朋友，我和他们一起去了公园。
大学英语语法应用教程-从句(Clause)
从句(Clause)
If two numbers are to be added, it does not matter in which order they are added. 若要把两个数加起来，那么按哪种顺序相加是没有关系的。(需要注意的是，连接代词which并没有位于主语从句句首， 因为它在从句中作介词in的介词宾语和order的定语。而且，不要把由which引导的主语从句误认为是介词宾语从句。) It follows from Maxwell’s hypothesis that whenever there netic field is produced. 由麦克斯韦假设可知，每当电场发生变化时就产生磁场。 (it follows that … 意为“由此得知……；因此”。) It happened that she was out when he called.( = She happened to be out when … ) 他打电话时，她恰巧不在家。(It happens that可译成“碰巧，恰巧；发生”。)
从句(Clause)
3) 表语从句 主要位于系动词be之后的表语从句最为常见，当然，也可用seem, sound等。例如： The present conception of the general structure of the atom is that it consists of a kind of solar system. 现在对 原子的一般结构的看法是：它是由一种太阳系构成的。 All indications are that the need for skilled people in the field of electronics will grow in this new decade. 所有 的迹象表明，在这新的十年中对电子学领域熟练人员的需求量将会增长。 That is how a computer works. 这就是计算机的工作原理。 (本句中的that应译为“这”；how从句一般可译成“……的原理，……是如何……”) Predictions are that electronics will continue to grow at a rapid rate for some time to come. 预测表明，在未来 一段时期内电子学将会继续高速发展。 (That is why … 要译成“这就是……的理由；这就是为什么……；因此……”。) My plan is that we will finish the project by the end of the year. 我的计划是我们年底结束这个项目。 The conclusion of the discussion is that the proposal cannot be accepted. 讨论的结果是这个提议不能被接受。 在个别情况下，状语从句也可充当表语从句(特别是句型this is because … )。如： This is because you has been absent all the term. 这是因为你整个一学期缺勤的缘故。

定语从句语法专题（Attributive Clauses）教案一. 定语从句的概述:1.定语从句：在复合句中，修饰某一名词或代词的从句叫定语从句。
在句中做定语，被修饰的名词或代词，叫做先行词。
从句通常放在先行词之后，由关系词（关系代词或关系副词）引导。
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，一般紧跟在它所修饰的先行词后面。
eg She is the girl（who got the first prize.）girl先行词who充当从句主语, 从句做定语修饰girlThis is the boy who broke the window.这就是打破窗子的孩子。
the boy是先行词, who broke the window是限制性定语从句, 明确指出theboy是打破窗子的那个孩子,who 在从句中充当主语That is the house where he lived ten years ago.He is the man who/that lives next door.He is the man who I want to see.先行词关系词定语从句复合句: 是由一个主句和一个或一个以上的从句构成的句子, 复合句中的主句和从句都具有完整的的主语和谓语, 主句是复合句的主体, 可以独立存在, 从句需要有一个连词引导, 是修饰说明主句的, 不能独立存在, 根据在句中的不同作用, 从句可以分为三类: 定语从句, 名词性从句, 状语从句。
二. 引导定语从句的关系词有两大类:1.关系词：引导定语从句的关联词称为关系词，关系词有关系代词和关系副词。
关系代词: that, who, whom, whose, which, as（主, 宾, 定）关系副词: when, where, why.（状语）2.关系词的作用:（1）引导定语从句, 在先行词和定语从句之间起连接作用；（2）代替先行词在句中充当成分。
定语从句讲解
定语从句【知识简介】名词或代词由一个从句来修饰，该从句即定语从句。
定语从句一般后置，但as引导的修饰全句的定语从句可以前置。
引导定语从句的词有关系代词that, which, who, whom, whose, as等以及关系副词when, where, why等。
关系代词或关系副词放在被修饰的名词或代词（又叫做先行词）和定语从句之间起联系作用，同时又作定语从句中的一个成份。
【要点难点】1) that和which的用法区别只用that的情况：①先行词由最高级修饰时，如the best work that I can do。
②先行词由序数词修饰时，如the second book that I bought。
③先行词由the last, the only, the same, the very等修饰时。
④先行词是不定代词all, anything, everything, little, much, nobody, nothing等时，如anything that he does; all that I can do now等。
⑤先行词有any, no, all等限定词时，如all the words that I’ve learned。
⑥先行词为词组，该词组既含人又含物时，如the city and the people that I visited。
只用which的情况：①在非限定性定语从句中（定语从句前有逗号）。
②介词后。
请看that和which的使用例句：I t’s the best film that’s ever been made on the subject of madness. 这是以精神病为题材而拍摄的影片中最好的一段。
Shakespeare is the greatest poet that England has ever had. 莎士比亚是英国最伟大的诗人。
（本句中先行词虽是人，但由于前面也有形容词最高级修饰，仍用that较好）Take the first opportunity that offers. 抓住第一个出现的机会。
定语从句知识点讲解
定语从句知识点讲解定语从句是用来修饰名词或代词的从句。
它常常用来给出详细的描述、限制或补充说明，以便读者可以更好地理解主句中的名词或代词。
以下是几个关于定语从句的重要知识点：1.引导定语从句的关系代词和关系副词：- 关系代词有：who, whom, whose, which, that（指人或物）- 关系副词有：when, where, why（指时间、地点、原因）2.关系代词的选择：- 指人的先用who，做宾语用whom，所有格用whose，作主语用that （在口语中who/that可通用）- 指物的先用which，作宾语用which，作主语用that（在口语中which/that可通用）-当关系代词作主语时，可以省略（不可以省略的情况：关系代词后有逗号分隔、定语从句修饰不止一个名词）3.定语从句的位置：-定语从句通常紧跟在被修饰的名词或代词后面4.定语从句的种类：-限制性定语从句：不使用逗号分隔，修饰的内容是对名词或代词进行必要的限制和定义-非限制性定语从句：使用逗号分隔，修饰的内容是对名词或代词进行额外的说明，可以省略，不对整个句子的意思产生重要影响5.关系副词的使用：- when：指时间，修饰表示时间的名词- where：指地点，修饰表示地点的名词- why：指原因，修饰表示原因的名词6.注意定语从句的时态和语态一致：-如果主句是过去时，则定语从句通常使用过去时-如果主句是现在时，则定语从句通常使用一般现在时-如果主句是将来时，则定语从句通常使用一般将来时-如果主句是被动语态，则定语从句通常使用被动语态以上是定语从句的一些基本知识点，掌握了这些内容，可以更好地理解和运用定语从句。
当然，在实际运用中还需多加练习，不断积累。
定语从句相关知识点总结
定语从句相关知识点总结一、定语从句的概念。
1. 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。
- 例如：I like the book which/that is very interesting. 其中“book”是先行词，“which/that is very interesting”是定语从句，用来修饰“book”。
二、关系代词的用法。
1. that.- 既可以指人也可以指物，在从句中作主语或宾语。
- 当先行词是all, much, little, something, everything, anything, nothing, none等不定代词时，关系代词用that。
- 例如：All that can be done has been done.（先行词是“All”，关系代词“that”在从句中作主语）- 当先行词被序数词或形容词最高级修饰时，关系代词用that。
- 例如：This is the best film that I have ever seen.（先行词“film”被最高级“the best”修饰，关系代词“that”在从句中作宾语，可省略）- 当先行词被the only, the very, the same等修饰时，关系代词用that。
- 例如：This is the very book that I want.（先行词“book”被“the very”修饰，关系代词“that”在从句中作宾语）2. which.- 指物，在从句中作主语或宾语。
- 例如：The book which/that is on the desk is mine.（“which/that”在从句中作主语）；I like the book which/that you lent me.（“which/that”在从句中作宾语）- 在非限制性定语从句（从句与主句之间用逗号隔开）中，只能用which，不能用that。

Answer Analysis: The correct translation of this sentence is " 中了彩票的那个人现在成了百万 富翁。" The relative clause "who won the lottery" modifies "person". In Chinese, we use "那" to indicate the specific person, and "中了彩票 的" as the modifying phrase.
定语从句专项笔记总结
定语从句专项笔记总结定语从句专项笔记总结定语从句是由关系代词或关系副词引导的修饰名词或代词的从句，是一种形容词性的从句。
被修饰的名词或代词叫先行词。
1．关系代词：who whom whose which that关系代词引导从句，代替先行词，在从句中充当一个成分，如：主语、宾语、定语等，所以在作主语时，动词的数要和先行词的数保持一致。
who----可作主语、宾语，作主语时，只能用who, who作宾语时是非正式This is the man who helped me.whom---作宾语（正式用法），在介词后只能用whom人 This is the man whom I met in the street yesterday. (正式用法)This is the man who I met in the street yesterday. (非正式用法)whose-who的属格形式，用来指人，也可以用来指物that--- 可代替who ,whomWhich----可作主语，宾语物 eg. The watch which was lost has been found.eg.

This is the teacher whom he worked with .This is the teacher with whom he worked .eg. This is the book for which you asked.This is the book which you asked for.eg. This is the pen which he has been looking for. (look for词组中for不能提前)先行词是人时，常用who而不用that 的情况：a. 关系代词在从句中作主语时，多用who，eg. I will pardon him who is honest.b. 先行词为 all one ones anyone those 等时，eg.

Unit 11
Clause: Adjective clauses
• Grammar: Adjective clauses • Writing:
Correcting: Lack of Subject-Verb Agreement Rewriting: Inter-sentence coherence
• Why did he fail? • The reason is still obscure. • The reason why he failed is still obscure. • (why = for which; which = reason; as an adverbial of the clause.)
• He was really alive all the time.
• A long-lost brother, who was presumed dead, was really alive all the time.
• (As “brother” has a modifier “long-lost”, it is still clear without the clause.)
• The sun had set. • We returned to our hotel at once. • As soon as the sun had set, we returned to our hotel at
once.
• Now he knew it. • He would be able to reach the South Pole. • The South Pole was 300 miles away. • He now knew that he would be able to reach the South
Clauses
There are two kinds of clauses: main clause and subordinate clause. A main clause (or a simple sentence) contains a complete thought and therefore can stand alone as a sentence. Every sentence must contain at least one main clause (MC).
3. Introducers
3.1. In restrictive adjective clauses
The following relative pronouns are used to introduce restrictive adjective clauses.
Subject Object Possessive
• She forgot the name of the store. • At that store, her father bought her an MP4. • She forgot the name of the store where her father bought her
an MP4. • (where = at which; which = store; as an adverbial of the clause.)
Introducer + (subject) + predicate + …
• He picked up a long pipe. • The pipe was covered with coins. • He picked up a long pipe which was covered with coins. • (which = pipe, as a subject of the adjective clause.)
• A clown is a person. • He makes you laugh. • A clown is a person who makes you laugh. • (Without the clause, “A clown is a person” doesn’t make sense.) • Let’s go to a country. • In the country, the sun always shines. • Let’s go to a country where the sun always shines. • (Without the clause, “Let’s go to a country” doesn’t make the
Person who/that whom, who, that/ø whose
Things which/that which, that/ø whose
The following subordinating conjunctions are used in restrictive adjective clause.
• We were worried about our nearest neighbors.
• They were newcomers to the district.
• We were worried about our nearest neighbors, who were newcomers to the district.
• (As “our nearest neighbors” are clear, the sentence makes sense without the clause.)
• A brother was lost for a long time.
• People presumed him to be dead.
2. Kinds Adjective clauses can be divided into two kinds: restrictive and nonrestrictive. A restrictive adjective clause gives essential information. Without the clause, the complete meaning of the sentence would not be expressed clearly. A restrictive adjective clause should not be set off by commas.
• We waited for half an hour. • Nothing happened. • We waited for half an hour, but nothing happened.
A subordinate clause also has a subject and a predicate, but it cannot stand alone to make sense. It needs a main clause to complete its meaning. A subordinate clause is usually introduced by subordinating conjunctions or relative pronouns.
4. whom is very formal and is only used in written English. In spoken English, that is usually replaced by who/that, or nothing (ø).
5. that is usually used after the words like something, anything, everything, nothing, all and superlatives. There is something that we will never forget. That was the most exciting news that I have ever heard.
Pole, which was 300 miles away.
1. Functions and forms
An adjective clause is a sentence clause that modifies a noun or a pronoun as an adjective does. Both relative pronouns (who, whom, whose, that and which) and the subordinating conjunctions (where, when and why) may be used as introducers to begin adjective clauses.
• He caught sight of a figure. • He immediately recognized it. • It was our local grocer. • He caught sight of a figure whom he immediately
recognized as our local grocer. • (whom = figure, as an object of the adjective clause.)
• I can not remember the day. • At that day, they got engaged. • I can not remember the day when they got engaged.. • (when = at which; which = day; as an adverbial of the clause.)
meaning of the sentence clear.)
When an adjective clause is not absolutely needed in order to express the complete meaning of a sentence, it is called a nonrestrictive adjective clause. It can be omitted from a sentence without affecting the basic meaning of the sentence. It should be set offe
