限制性定语从句与非限制性定语从句

2．关系代词which与as引导非限制性定语从句的区别。

（1）which与as都可以引导非限制性定语从句，which引导定语从句要置于先行词后面，而as引导的定语从句位置相对灵活，可放在句首，也可以放在句后

eg.正像他所意识到的那样，我对他非常有用

As he realized, I was very useful to him.

空气，众所周知，是一种气体

Air, as we know, is a gas.

(2)当定语从句位于主句后面，纯粹表示主句所述的内容，往往用which；当定语从句中有“如同……那样”的含义时，用as比用which更常见。

Eg.妈妈老把我当成小孩对待，让我无法忍受

Mummy always treats me just like a baby, which I can’t bear.

事与愿违，这是常有的事

Things will turn out contrary to on e’s wishes, as is often the case.

(3)“介词+关系代词”结构的定语从句，必须用which,不能用as.

Eg.我们周围有很多氧气，没有他们我们无法生存

There is a great deal of oxygen around us, without which we could not live.

3．引导限制性定语从句时which与as的区别

定语从句前面有such, as, the same 时，引导定语从句的关系代词用as,不用which.

Eg 所需要的字典有许多都有了

There are as many dictionaries as needed.

他讲的那些故事我从没听过

I have never heard such stories as he tells.

我们正面临着和多年以前同样的困境

We are facing the same problems as we did years ago.

高中非限定性定语从句教案

教学过程 一、复习预习 定语从句是由关系代词或关系副词引导的从句，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。 定语从句又分为限制性定语从句和非限制性定语从句。限制性定语从句对被修饰的先行词有限定制约作用，使该词的含义更具体，更明确。限制性定语从句不能被省略，否则句意就不完整。非限制性定语从句与先行词关系不十分密切，只是对其作一些附加说明，不起限定制约作用。如果将非限制性定语从句省去，主句的意义仍然完整。本节我们着重研究限定性定语从句。 二、知识讲解 非限制性定语从句：从句和先行词关系不密切，去掉定从句，意思仍然完整。形式上用逗号隔开，不能that用引导。 e.g. Tom’s father, who is over sixty, still works hard day and night.（who引导非限 制性定语从句，整个句子可分成两句来翻译） 考点/易错点1 非限定性定语从句中which和as均可使用，一般情况下，逗号后which表示预料之外的事情，而逗号后的as则表示预料之内的事情，e.g. He didn’t come, which surprised u s.他没有来，我们非常吃惊； He didn’t come, as we had expected.他没有来，正如我们所料。 考点/易错点2 which可以在特殊定语从句中作定语，修饰fact, matter, thing 等名词。这些名词代表先行成

分表达的意义，有时将其略去句义仍然完整。as不能作定语。如： I was told to go not by train but bus, which advice I followed. 考点/易错点3 同时注意一个问题，限定性和非限定性定语从句在语义上有时略有差别： There are 5 people, who were injured in the accident. （表示共5个人） There are 5 people who were injured in the accident. （表示人很多，但受伤的只有5个） He didn’t wear clothes which will distinguish him from others. 他不穿那些会把他和别人分开的衣服。（他不穿奇装异服） He didn’t wear clothes,which will distinguish him from others. 他不穿衣服，这把他和别人分开。 造成这样歧义的原因就在于逗号的which课表示前文整句话。 考点/易错点4 as引导定语从句时的用法 ①as引导限制性定语从句通常用于the same … as, such … as结构中。 e.g. I want the same shirt as my friend’s. 我要一件跟我朋友一样的衬衫。 Such machines as are used in our workshop are made in China. 我们车间使用的这种机器是中国制造的。 ②as引导非限制性定语从句既可放在主句之前，也可放在主句之后，用来修饰整个句子。通常用下列句型：as is known to all, as is said, as is reported, as is announced, as we all know, as I expect 等。 e.g. As I expected, he got the first place again in this mid-term examination. 正如我所预料的那样，他在这次期中考试中又获得了第一名。 3）as 引导非限制性定语从句时与which的区别 ①当主句和从句语义一致时，用as；反之，用which来引导非限制性定语从句。 e.g. He made a long speech, as we expected. He made a long speech, which was unexpected. ②当非限制定语从句为否定时，常用which引导。 e.g. Tom drinks a lot every day, which his wife doesn’t like at all. 三、例题精析 【例题1】 【题干】___________ is known to everybody, the noon travels around the earth once every month.(NMET 2001) A.It B.As C.That D.What 解析：答案为B。本题考查as引导的非限制定语从句。as作“正如……”解时，引导的非限制性定语从句来修饰整个句子。当as在从句中作主语时，常用于下列短语：as is known、as is said、as is reported、as is announced等。要注意掌握作关系代词引导定语从句的用法。 【答案】B 【解析】

定语从句与基础写作

非限制性定语从句 一、与限制性定语从句的区别： 限制性定语从句是不能去掉的，否则剩下的部分就失去意义而不能成立。非限制性定语从句则不然，它只对所修饰的词作进一步的说明，去掉之后并不影响整个句子的含义。在形式上，非限制性定语从句与主句之间通常必须有逗号隔开。试比较： ①A man who doesn’t want to learn from others can’t achieve much. ②I come from China, which has a long history of 3000 years. 二、as和which的区别 翻译下列句子，然后找出每句的先行词。 1. A five-year-old boy can speak two foreign languages, which surprises me. 2.The weather turned out to be very good, which was more than we could expect. 3.Tom is tall, as are his brothers. 4.As we all know, paper was first made in China. 归纳：as和which在非限制性定语从句中可代替整个主句。 as可用在固定搭配中 as anybody can see正如人人都能看到的那样 as has been said before如前所说 as often happens 正如经常发生的那样 as has been pointed out 正如已指出的 as we all known/ as is well known to us众所周知 as mentioned above如上所述 1.___________ often happens, he is late again. 2.He came here very late, ____________ was unexpected. 3.He has passed the text, ___________ nobody knows. 4.Tom has made rapid progress, ____________ makes me very happy. 5.Mother was terrified, ____________ I could see from her eyes. 6.Our team lost the game, ____________ was reported in the newspaper. 巩固练习： 一、完成句子。 1.射击最初只是生存工具，19世纪末才发展成为一项体育运动。 Shooting, _________was a means of survival originally, developed into a sport only in the late 19th century. 2.中国吸烟人数：约 3.5亿；分布：男性75％;女性：25％ Currently China has about 350 million smokers, among _________75% are men and 25% are women. 3.受二手烟影响人数：约5.4亿；因二手烟死亡人数：超过10万/年 Around 540 million people are affected by second-hand smoke, ________causes 100,000 deaths per year. 4.众所周知，2008年北京将举办奥运会。英语作为一种国际语言，将会在交流 中起着重要作用。作为一名高三学生，我们应抓住现在的学习机会努力学好它。只有这样，才能为奥运贡献自己的力量。 _________ is known to all, Beijing will host the 2008 Olympic Games. English, __________ is an international（国际的）language, plays an important part in communicating（沟通、交流）with foreigners. We Senior Three students should catch this opportunity（机会）to learn it well, by __________ we can make our contribution （贡献）to the Olympic Games. 二、英译汉。 1.Don’t cheat me. I’m no longer the boy that I was three years ago. ______________________________________________________________________ 2.There is no difficulty that cannot be overcome. ______________________________________________________________________

优秀教案 定语从句

定语从句（复习课） 一、热点考点回顾 一、基本概念 （一）定语从句 在复合句中作定语，修饰名词或代词的从句叫定语从句。 （二）先行词 被定语从句所修饰的名词或代词。一般情况下，定语从句紧跟先行词。但也有因各种原因定语从句与先行词被分割的现象。 （三）关系代词和关系副词 定语从句的引导词。与先行词关系密切，因此紧跟先行词，并在定语从句中充当一个成分。关系代词有：who, whom, which, that和whose, 另外，as也可充当关系代词。关系代词在定语从句中充当主语、宾语、表语和定语。关系副词有：when, where和why。在定语从句中充当状语。 （四）分类：限制性定语从句和非限制性定语从句 1，限制性定语从句：用来修饰和限制先行词，是复合句中不可缺少的组成部分。若将它去掉，先行词的意思就不明确，主句也不完整。 Eg: I know the girl that attened the party. 我知道参加聚会的那个女孩。 I met someone who said he knew you. 我遇到一个说认识你的人。 He came from a family which was very poor.他来自一个贫穷的家庭。 2，非限制性定语从句：对先行词的附加说明，说若省去也不影响主句的意思，它和主句之间常用逗号隔开。 Eg: His mother, who loves him very much, is strict with him.他的妈妈很爱他，对他很严格。 China, which was founded in 1949, is becoming more and more powerful.成立于1949年的中国变得越来越强大。 二、关系代词的用法 （一）基本用法 根据先行词的不同，和在从句中所充当的成分不同，选用不同的关系代词。

书面表达写作技巧之三：如何写好定语从句

二轮复习书面表达写作技巧之三：如何写好定语从句 定语从句的正确使用能够比较明显地反映出考生对于语言具有较高的掌握能力，所以建议考生一定要在写作中至少使用一个恰到好处的定语从句。 (一)定语从句的类型 1．关系代词引导的定语从句 关系代词who, whom, whose, that, which, as引导的定语从句是写作的一大重点，尤其是which和as引导的非限制性定语从句在高考范文中更是屡见不鲜。 ①(2018?北京高考书面表达)Last week, we took the foreign students to experience the authentic tea culture, which turned out to be extremely rewarding.上周，我们带领外国学生体验了正宗的茶文化，结果证明非常值得。 ②(2017?全国卷Ⅲ书面表达)Secondly, you will make some good friends who are also interested in playing table tennis.第二，你会交到一些好朋友，他们也很喜欢打乒乓球。 ③As you see, the Chinese people are hard-working. 你知道，中国人民是勤劳的。 2．关系副词引导的定语从句 关系副词引导的定语从句是指when, where, why引导的定语从句。

①(2018?北京高考书面表达)Its Chinese Literature major is perfect for you where you can be completely soaked in Chinese profound history and rich culture. 它的中国文学专业对你来说是适合的，在那儿你可以完全沉浸在中国深厚的历史和丰富的文化中。 ②(2014?安徽高考书面表达)I think the reason why you are always angry may be the high pressure of study. 我认为你总是发脾气的原因可能是学习上的巨大压力。 3．“介词＋which/whom”引导的定语从句 (2017?北京高考书面表达)Material collecting took us a whole week, during which we interviewed our teachers and took pictures of every aspect of school life. 搜集材料花了我们整整一周的时间，在此期间我们采访了老师并拍摄了学校生活的各个方面。 (二)定语从句的写法 定语从句是比较难掌握而又是考生在写作中喜欢尝试的复杂句，在写作时可采用“三步法”： [示例] 第一步：写出两个简单句。 ①The foreigner is from Canada. ②He visited our class yesterday.

which在非限制性定语从句的用法

非限定性定语从句起补充说明作用，缺少也不会影响全句的理解，在非限定性定语从句的前面往往有逗号隔开，如若定语从句有限制性和非限制性两种。限制性定语从句是先行词不可缺少的部分，去掉它主句意思往往不明确；非限制性定语从句是先行词的附加说明，去掉了也不会影响主句的意思，它与主句之间通常用逗号分开，将非限定性定语从句放在句子中间，其前后都需要用逗号隔开。 which引导的非限制性定语从句。 关系代词which在非限制性定语从句中所指代和修饰的可以是主句中的名词、形容词、短语、其他从句或整个主句，在从句中作主语、动词宾语、介词宾语或表语。 ① which指代主句中的名词，被指代的名词包括表示物、婴儿或动物的名词、表示单数意义的集体名词以及表示职业、品格等的名词。 如：These apple trees，which I planted three years ago，have not borne any fruit. 这些苹果树是我三年前栽的，还没有结过果实。 She is an artist，which I am not. 她是一位艺术家，而我不是。 Water，which is a clear liquid，has many uses. 水是一种清澈的液体，有许多用途。 The two policemen were completely trusted，which in fact they were. 那两个警察完全受到信任，事实上，也真是如此。 ② which指代主句中的形容词。 如：She was very patient towards the children，which her husband seldom was. 她对孩子们很耐心，她丈夫却很少这样。 She is always careless，which we should not be. 她总是马虎大意，我们可不应该这样。

限制性定语从句与非限制性定语从句的六点区别 区别一：形式不同 限定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；而非限定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。 区别二：功能不同 限定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；而非限定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。如： People who take physical exercise live 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。(若把从句去句子意义仍然完整) 区别三：翻译不同 在翻译定语从句时，一般把限定性定语从句翻译在它所修饰的先行词之前，而把非限定性定语从句与主句分开。如： He is the man whose car was stolen. 他就是汽车被窃的那个人。 I’ve invited Jim, who lives in the next flat. 我邀请了吉姆，他就住在隔壁。 区别四：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) 区别五：先行词不同 限定性定语从句的先行词只能是名词或代词，而非限定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。如： Peter drove too fast, which was dangerous. 彼得开车很快，这是很危险的。(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)

非限制性定语从句-教学设计

《非限制性定语从句》微课程教学设计 一．教材分析：本节内容为非限制性定语从句，它是定语从句中的一个重要知识点。定语从句在高中阶段是学生学习的热点，同时也为难点。在学习限制性定语从句将为学习非限制性定语从句打下基础，同时，如何区分限制性和非限制性定语从句也成为学生的困扰，那么本节课主要介绍如何区分非限制性定语从句以及它的定义和用法。 二．学生分析：由于我的学生是刚跨入高中的高一新生，语言和语法知识大部分都停留在初中阶段，定语从句的概念对于他们来说是一个新的知识点，而且难度比初中的知识增大了不少。但是由于他们已经学习过了限制性定语从句，所以理解非限制性定语的用法将会比较容易。 三．教学目的 1．知识和技能目的：熟悉和掌握非限制性定语从句的用法 2．情感和价值观目的：提高学生的学习兴趣 3．能力目的：提高学生的理解和阅读能力 四．教学重难点 1 重点：掌握非限制性定语从句的用法 2 难点：学会使用非限制性定语从句，并用它造句。 五．教学过程 Step 1.
