1、教学课件考点23 限制性定语从句与非限制性定语从句高考频度：考向一 非限制性定语从句非限制性定语从句是对意义已经非常明确的先行词给予补充、说明，删去非限制性定语从句，主句的意思仍是概念清晰、结构完整的。非限制性定语从句的引导词有who，whom，which，whose，as，when，where等，that不可用于引导非限制性定语从句，从句之前要用逗号。先行词指人，则用who，whose，which等；先行词指物，要用which；先行词表时间或者地点，并在句中作时间状语或者地点状语时要用when或者where引导。一、使用非限制性定语从句的情况：1. 关系代词指代整个主句时，使用非限制性定语从
2、句。You did a lot for me, for which I was grateful. 你为我做了许多，对此我很感激。The Diaoyu Island belongs to China, as is known to us. 众所周知，钓鱼岛属于中国。A middle-aged woman killed her husband, which frightened me very much. 一个中年女子杀害了自己的丈夫,这令我十分恐惧。2. 当先行词指的是世界上独一无二的事物或人名地名等专有名词时，使用非限制性定语从句。China, which is my motherland,
3、 is developing fast. 中国是我的祖国，正在快速发展。Eason, who was a pop star, got married last year. 伊森去年结婚了，他是明星。Last Sunday they reached Nanjing , where a conference was to be held. 他们上周日到达南京，有个会议要在那里举行。3. 当先行词指的是某人只有一个亲属（son，daughter等）时，使用非限制性定语从句。He has a daughter, who is studying in London. 他有个女儿，现在正在伦敦学习。（只有
4、一个女儿）This is my teacher, who has something to tell you. 这是我的老师，他有一些事情要告诉你。二、限制性定语从句与非限制性定语从句的区别1. 形式不同 限制性定语从句主句和从句之间不用逗号隔开，口语中使用时也不停顿；而非限制性定语从句与主句之间通常有逗号隔开，口语中使用时有停顿。 2. 功能不同 限制性定语从句用于对先行词的意义进行修饰、限制和识别，如果去掉，就会造成句意不完整或概念不清；而非限制性定语从句用于对先行词起补充说明作用，如果省略，句意仍然清楚、完整。People who take physical exercise live
5、longer. 进行体育锻炼的人活得长些。(若把从句去掉句子就失去意义) His daughter, who is in Boston now, is coming home next week. 他女儿现在在波士顿，下星期回来。(若把从句去掉，句子意义仍然完整) 3. 翻译不同 在翻译定语从句时，一般把限制性定语从句翻译在它所修饰的先行词之前，而把非限制性定语从句与主句分开。He is the man whose car was stolen. 他就是汽车被窃的那个人。 Ive invited Jim, who lives in the next flat. 我邀请了吉姆，他就住在隔壁。 4
6、. 含义不同 比较下面的两个句子： I have a sister who is a doctor. 我有一个医生的姐姐。(姐姐不止一个) I have a sister, who is a doctor. 我有一个姐姐，她是当医生的。(只有一个姐姐) 5. 先行词不同 限制性定语从句的先行词只能是名词或代词，而非限制性定语从句的先行词则可以是名词或代词，也可以是短语或句子；另外，当先行词为专有名词或其他具有独一无二性的普通名词时，通常要用非限制性定语从句，而不用限制性定语从句。Peter drove too fast, which was dangerous. 彼得开车很快，这是很危险的。(
7、which指drive too fast) He changed his mind, which made me very angry. 他改变了主意，这使我很生气。(which指整个主句)Mr. Smith, who is our boss, will leave for Japan next week. 我们的老板史密斯先生下周要去日本。(先行词为专有名词，要用非限制性定语从句修饰) Her father, who has a lot of money, wishes her to study abroad. 她父亲很有钱，希望她出国学习。(先行词为表独一无二意义的普通名词，要用非限制性定
8、语从句修饰) 6. 关系词不同 关系词that和why可用于限制性定语从句中，通常不用于非限制性定语从句；另外，在限制性定语从句中，关系词有时可以省略，而在非限制性定语从句中关系词一律不能省略。1.(2018北京卷单项填空) She and her family bicycle to work, _ helps them keep fit.A. which B. who C. as D. that【参考答案】A2.（2017新课标卷I语法填空）Like anything, it is possible to have too much of both, 70 is not good for t
