高中专题讲解-定语从句.docx

课题 定语从句教学目标 熟悉定语从句的概念、句法结构和作用以及先行词和关系词的位置和作用; 掌握关系词在定语从句中的应用技巧学情分析： 高考必考知识点，主要考查其基本用法，近几年注重了定语从句在其他从句的混合考查。其中which（介词+which）和where 的应用应重点理解记忆。定语从句一 基本概念：A. 定语： 修饰名词或代词的词、短语或从句。Gilin is a beautiful city.China is a developing country; America is a developed country.There are thirty women teachers in our school.His rapid progress in English made us surprised.Our monitor is always the first to enter the room.He is reading an article about how to learn English.B. 定语从句： 在复合句中，修饰一个名词或代词的从句；分类： 限定性定语从句 无逗号隔开 非限定性定语从句 有逗号隔开从句位置： 在先行词之后（必须）先行词： 被定语从句所修饰的词叫先行词；关系词: 引导定语从句的词. 关系代词：who, whom, whose, which, that 关系词 关系副词: when, where, why 连接词： as（唯一可置于先行词之前）This is the man who helped Jack yesterday. 先行词 关系词分析： I work in a company which produces planes.先行词： 关系词： 关系词的作用 引导定语从句 代替先行词在句中充当成分关系代词： who, whom, whose, that, which, as (在定语从句中担任主、宾、表、定) 在定语从句中担任主语的是： who, that, which, as 宾语的是： who, whom, that, which, as 定语的是： whose, which 先行词为人，可用的关系词是： who, whom, that, as 先行词为物，可用的关系词是： which, that, whose, as关系副词： when(先行词为时间)， where(先行词为地点)， why（先行词为原因）， 关系副词= 介词 + which/whom.二 定语从句类型概况了解限制性定语从句和非限制性定语从句的区别：区别点限制性定语从句非限制性定语从句与先行词之间的关系紧密，删除后影响整个句子表达疏松，只是补充说明，删除后不影响整个句子表达逗号的有无其前不用逗号其前有逗号That 的使用可用不可用Which/who 在从句中作宾语是否可省略可省略不可省略Whom 在从句中作宾语是否可用that/who代替可替代不可替代是否可修饰句子不可可以，此时有逗号隔开，只能由which/as引导翻译时的区别常译为前置定语，“的”常译为并列分句读时是否停顿不停顿停顿，用降调Eg: (辨析)1. The teacher told me that Tom was the only person that I could depend on.2. China is a country which has a long history.3. His mother, who loves him very much, is strict with him.4. China, which was founded in 1949, is becoming more and more powerful.什么时候使用非限制定于从句呢？1. 关系代词指代整个主句的内容时She said she had finished her work, which I doubted very much. As most people know, Fujian is famous for tea.He was generous with his time, for which I was grateful.他十分慷慨的给予我时间，我为此非常感激。2. 先行词是世界上独一无二的事物或专有名词时The moon, which is 384,400 kilometers away from the earth, creates many beautiful stories. 月球，这个离地球384,400 千米远的星球，给人们带来了很多美好的故事。We all honour and respect Albert Einstein, who is the greatest physicist in the world. 我们都敬重这位世界上最伟大的物理学家爱因斯坦。 特殊形式的定语从句1. 分隔式定语从句为某种特殊的需要，与先行词分离开的定语从句I have a picture by a famous painter which was sent to me for my birthday.我有一副出自名家笔手，送给我作为生日礼物的话。（被介词短语分开） The days are gone when we lived together, worked together and played together. 我们一起居住、工作和玩耍的日子一去不复返了。（被谓语分开）2. 混杂式定语从句定语从句的关系词与其后的词之间有一个像I think, I believe, I guess, I expect, I am sure, they say等类似插入语，使定语从句更加复杂。James is the only one who we expect will win.The girl knows three foreign languages, which we all think makes it easier for her to find a good job. 3. 多重定语从句两个或多个定语从句同时修饰一个先行词I find it hard to leave the land where I have lived for 30 years and where there are sweet memories of my childhood.Ill never forget the moment when I first met Mary and which makes me always feel happy.三 关系词A 关系代词 指代先行词，在定语从句中作主语、宾语、表语等。注意a. 作宾语时，口语中常省略b. 作介词宾语且介词提到关系代词前面，关系代词不可省略。 who, whom, whose, which, that1.
