23、限制性定语从句：关系代词 一、定语从句的定语及分类 （什么样的从句是定语从句？定语从句有哪几类？如何区分？） 教学目标：通过定语，引入定语从句的定义，要求学生： 理解定语从句的定义；明白掌握定语从句定义的用处，并学会判别一个从句是否 为定语从句。 定语定语从句 定什么是定语什么是定语？什么是定语从句什么是定语从句？ 5 义（1）对名词起描绘、修饰、限定作用 的结构。 （2） （完整版）放在一个名词前或名 词后，对该名词起描绘、修饰、限定 作用的结构。 （被修饰的名词，叫名次中心词） （1）作定语的从句，叫定语从句。 （2） （完整版）放在先行词（名词、代 词、或一句话）后面，对该先行词起描 绘

24、、修饰、限定作用的从句，叫定语从 句。 （被修饰的名词、代词或一句话，叫先 行词） （3）放在先行词后，起描绘、修饰、 限定作用的从句，叫定语从句。 词 性 定语，一般由形容词来充当。 （名词、地点副词、介词短语、非谓 语动词也可以修饰名词，充当定语） a good book （形容词） the people present （地点副词） the boy in the classroom （介词短语） falling leaves （非谓语动词 ing 分 词） fallen leaves （非谓语动词 ed 分词） leaves fallen to the ground（非谓语动 词 ed

25、分词） the coming day（非谓语，-ing 分词） the day to come（非谓语动词，-to do 不定式） 定语从句又被叫做形容词性从句。 位 置 根据定语与被修饰名词之间的先后顺 序，分为： （1）前置定语）前置定语： a good book falling leaves fallen leaves the coming day （2）后置定语）后置定语： the people present the boy in the classroom the day to come leaves fallen to the ground leaves, fallen to t

26、he ground 根据定语从句的定义，可知：定语从句 一般要放在被修饰的先行词的后面： The book that/ which he bought yesterday is interesting. 先行词（名词）定语从句 There was nobody who she could turn to for help. 先行词（代词）定语从句 He always sings highly of his part in the project(,) which makes others unhappy. 先行词（一句话） 定语从句 特例特例： as 引导的定语从句可以放在句首引导的定语从句可

27、以放在句首。 As we know, the earth goes around the sun. 分 类 限制性定语： a good booklling leaves fallen leavesthe coming day the people present the boy in the classroom leaves fallen to the ground the day to come 限制性定语从句 The book that/ which he bought yesterday is interesting. She has a sister who is a lawyer.

28、非限制性定语从句 Thebook,that/whichhebought 6 非限制性定语 leaves, fallen to the ground yesterday is interesting. She has a sister, who is a lawyer. 13.2.1 陈述定语从句的定义，并找出下列划线部分中的定语从句。 1. I dontknow who he is. 2.

30、 As he is ill, he cant go to school today. 13. As we all know, the earth goes around the sun. 14. He went to the station early in order that he could catch the early train. 二、定语从句引导词（即：先行词）的分类、句法功能（即：关系词在句子中所作的成 分） （关系词分哪几类？关系词在从句中可以作什么成分？） 教学目标：通过特殊疑问词，引入定语从句关系词，要求学生： 理解关系代词、关系副词的作用；借助关系代词的十句话，以及两组

31、关系，达到 数量判断、正确选用核实的关系词。两组关系为：1）谓语动词个数1=连词个数；2） 看从句中少不少成分。 关系代词的十句话： 只用 that 不用 which 的三句话： （定语从句中），先行词既指人又指物； 先行词由指物的复合不定代词充当； 先行词前有序数词、最高级、the very, the only, the last 以及 some, any,no 等数量限定词修饰。 只用 which 不用 that 的三句话 先行词由一句话充当； 先行词指物的非限制行定语从句； 先行词指物，关系词前有介词。 只能用 who/whom 不能用 that 的三句话： 先行词由指人的复合不定代词充

32、当； 先行词指人的非限制性定语从句； 先行词指人，关系词前有介词。 只用 as 的一句话： 先行词前有 the same, as, so, such 修饰。 总结以上 10 句话，可以得出下面的结论： 在选择定语从句的关系代词时，我们只用看三点就可以啦： 先行词由谁来充当； 先行词由谁来修饰； 关系词前有无逗号或介词。 特殊疑问词关系词 7 1、疑问代词在句中作主、宾、表、 定 Who are you? 表语 What are you doing? 宾语 Who(m) are you looking for? 宾语 Which do you like best? 宾语 Who broke th

34、地点状语 Why are you late again? 原因状语 How do you go to school every day? 方式 状语 2、关系副词 conj. 连接主从句；在从句中作状语 Thedayswhenwelivedthereare unforgettable. 时间状语 This is the factory where we once worked. 地点状语 We dont believe the reasons why he was absent. 原因状语 注意：how 不能引导定语从句 关系代词 conj. 连接主从句；在从句中 作主、宾、表、定 which

35、指物、一句话主、 宾、 表 that指人、物主、 宾、 表 who指人主、 宾、表 whom指人 宾、表 as指人、物、一句话 主、 宾、 表 whose指人、物定 知识点学习 题解题做 8 关系副词 conj. 连接主从句；在从句中 作状语 when先行词指时间时间状 语 where先行词指地点地点状 语 why先行词指原因原因状 语 结题三大步： 1、看谓语个数与连词个数 是否存在从句？ 2、是否是定语从句？ 2、从句中少不少成分 用关系代词？还是用关系副词？ 先行词指人？指物？指时间？指地点？指原因？有无特殊情况存在？ 三、 关系代词的正确选用（方法：看从句中少不少成分+先行词后移） （

36、如何正确地选用合适的关系词？） 9 四、定语从句解题思路分解 第一步、是否为定语从句 不是定语从句按相应从句的方法、步骤解题。 是定语从句按下列方法、步骤结题。 第二步、从句中是否缺少成分（主宾表定） 不少成分应选用关系副词 先行词指时间关系副词选用 when; 先行词指地点关系副词选用 where; 先行词指原因关系副词选用 why。 少成分（定语）关系代词选用 whose; 少成分（主宾表）按照以下步骤进行选择关系代词： 第三步、先行词指人还是指物 先行词既指人又指物关系词选用 that 先行词指人关系词选用 that, who, whom 先行词指物关系词选用 that, which 第

37、四步、限制性定语从句还是非限制性定语从句 That 不能引导非限制性定语从句。 第五步、是否有特殊情况 先行词既指人又指物关系词选用 that 先行词由指物的不定代词(everything, something, nothing, those, all)充当关 系词选用 that 先行词前有序数词、最高级，以及 the very ,the only 修饰关系词选用 that 10 先行词由指人的不定代词(somebody, anybody, everybody, someone, anyone, everyone, those, all)充当关系词选用 who 或 whom 先行词指人，关系词

38、前有介词时关系词选用 whom 先行词指人的非限制性定语从句关系词选用 who 或 whom 先行词由一句话充当关系词选用 which 先行词指物，关系词前有介词时关系词选用 which 先行词指物的非限制性定语从句关系词选用 which 先行词前有 the same, as, so, such 修饰时关系词选用 as 第六步、检验先行词后移 注意：区分定语从句与主语从句、同位语从句、结果状语从句和强调句 五、写作五、写作新闻报道小结 写作储备写作储备 阅读教材 P.55Summary，提炼概要写作的写作方法。 I. 文体特点文体特点 概要写作具备说明重点和简短这两个特点。要求考生能够抓住原文
