定语从句 一学习目标 1.熟练掌握定语从句 二考点解析 ⊙定从的功能—解释说明 This is the factory that/which can produce such machines 这就是能制造这种机器的工厂This is the factory that/which we visited last week 这就是我们上周参观的工厂 ⊙定语从句 定义：一个简单句跟在名词或代词后（先行词）进行修饰限定，就叫做定语从句。这个简单句在主句中充当定语成分。 I bought a cow that looked like a horse. ⊙定语从句怎么考？ 语法 22.I live next door to a couple children often make a lot of noise.（2016高考北京卷） A.whose B.why C.where D.which 完形 Balto put his nose to the ground, 52 to find the smell of other dogs that had traveled on the trail. （2016高考北京卷） 阅读&写作 A nurse who understands the healing(治愈) value of silence can use this understanding to assist in the care of patients from their own and from other cultures.（2016高考全国卷D篇） Last year, I spent all my time looking for a job where, without dealing with the public , I could work alone, but still have a team to talk to. （2016高考北京卷阅读A篇） ⊙定从原理：把两个句子合为一个，两个句子有相同的部分，此时可以把其中一个句子作为另一个句子的修饰限定部分。
定语从句：精讲精例精练 一、定语从句及相关术语 1. 定语从句：修饰一个名词或代词的从句称为定语从句, 一般紧跟它所修饰的先行词后面。 2. 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。 ①关系代词：that, which, who, whom, whose, as 等； ②关系副词：where, when, why等。 3. 关系词的作用： ①引导定语从句；②代替先行词；③在定语从句中担当一个成分。 二、关系代词引导的定语从句 1.who指人, 在从句中做主语 (1) The boys who are playing football are from Class One. (2) Yesterday I helped an old man who lost his way. 2. whom指人, 在定语从句中充当宾语, 常可省略。 (1) Mr. Liu is the person (whom) you talked about on the bus. (2) Mr. Ling is just the boy whom I want to see. 注意：关系代词whom在口语和非正式语体中常用who代替, 可省略。 (3) The man who/whom you met just now is my friend. 3. which指物, 在定语从句中做主语或者宾语, 做宾语时可省略 (1) Football is a game which is liked by most boys. (2) This is the pen (which) he bought yesterday. 4. that指人时, 相当于who 或者whom；指物时, 相当于which。在宾语从句中做主语或者宾语, 做宾语时可省略。 (5) The number of the people that/who come to visit the city each year rises one million. (6) Where is the man that/whom I saw this morning? 5. whose通常指人, 也可指物, 在定语从句中做定语 (1) He has a friend whose father is a doctor. (2) I once lived in a house whose roof has fallen in. whose指物时, 常用以下结构来代替 (3) The classroom whose door is broken will soon be repaired. (4) The classroom the door of which is broken will soon be repaired. (5) Do you like the book whose cover is yellow? (6) Do you like the book the cover of which is yellow? 三、介词+关系代词引导的定语从句 关系代词在定语从句中做介词宾语时, 从句常由介词+关系代词引导 (1) The school (that/which) he once studied in is very famous. (2) The school in which he once studied is very famous. (3) Tomorrow I will bring here a magazine (that/which) you asked for. (4) Tomorrow I will bring here a magazine for which you asked. (5) We'll go to hear the famous singer (whom/that/who) we have often talked about. (6) We'll go to hear the famous singer about whom we have often talked.
1K411032 城镇道路基层施工技术 一、石灰稳定土基层与水泥稳定土基层 （一）材料与拌合 (2)城区施工应采用厂拌（异地集中拌合）方式，不得使用路拌方式；以保证配合比准确且达到文明施工要求。 (3)应根据原材料含水量变化、集料的颗粒组成变化，及时调整拌合用水量。 （二）运输与摊铺 （1)拌成的稳定土类混合料应及时运送到铺筑现场。水泥稳定土材料自搅拌至摊铺完成，不应超过3h。 (2)运输中应采取防止水分蒸发和防扬尘措施。 (3)宜在春末和气温较高季节施工，施工最低气温为5℃。 (4)厂拌石灰土类混合料摊铺时路床应湿润。 (三)压实与养护 (1)压实系数应经试验确定。 (2)摊铺好的石灰稳定土应当天碾压成活，碾压时的含水量宜在最佳含水量的±2%范围内。水泥稳定土宜在水泥初凝前碾压成活。 (3)直线和不设超高的平曲线段，应由两侧向中心碾压；设超高的平曲线段，应由内侧向外侧碾压。纵、横接缝（槎）均应设直槎。 (4)纵向接缝宜设在路中线处，横向接缝应尽量减少。 (5)压实成活后应立即洒水（或覆盖）养护，保持湿润，直至上部结构施工为止。 (6)养护期应封闭交通。 一、石灰稳定土基层 （一）材料 (2)宜用1～3级的新石灰，其技术指标应符合规范要求；磨细生石灰，可不经消解直接使用，块灰应在使用前2～3d完成消解，未能消解的生石灰块应筛除，消解石灰的粒径不得大于10mm。 （二）拌合运输 (1)石灰土配合比设计应准确。通过配合比确定石灰最佳含量和石灰土的最佳含水量，达到设计要求的7d无侧限抗压强度的要求。 (2)应严格按照配合比拌合，并根据原材料的含水量变化及时调整拌合用水量。
定语从句 1什么是定语从句？ 由一个完整的句子充当定语的从句为定语从句。 2特点：和其它类从句比较，除了有引导词（关系词）定语从句有“先行词”。 3什么是先行词：被定语从句修饰的名词/代词为先行词。 4定语从句的种类：限定性定语从句和非限定性定语从句。 5定语从句引导词（关系词）的种类：关系代词和关系副词。 例：I work in a school which was built 50 years ago. 在此句中”school”为先行词，which 来引导定语从句，“which was built 50 years ago.”整句话来修饰先行词做定语，所以这是个定语从句。 注：定语从句的引导词通常置于先行词之后引导定语从句。（一）代词性引导词和副词性引导词，即关系代词和关系副词。代词性引导词有：that,which,who,whom,whose,as等，副词性引导词有：when,where,why等，代词性引导词在定语从句中充当主语/宾语，副词性引导词在定语从句中充当状语。 注：what 不能引导定语从句，因为what从句属于名词性从句。（二）基本用法。 1．先行词性质不同要使用不同的引导词，先行词指人时，可用that,who,whom代指，who与whom的区别在于who是主格，在从
句中作主语，whom是宾格，在从句中作宾语，而that作主语/宾语均可。先行词指物时，用that/which代指，可见，that既可代指人的先行词，也可代指物的先行词。 例：Do you know the man that is standing by the door? 此句that 引导定语从句，代指先行词the man. 例：This is the book that I have been looking for . 此句that引导定语从句，代指先行词the book. 例：This is the book which I have been looking for. 此句which引导定语从句，代指先行词the book. 例：Do you know the man who is standing by the door? 此句who 引导定语从句，代指行行词the man,作从句的主语。也可用that引导从句，如” Do you know the man that is standing by the door?” 例：The lady whom we saw this morning is Mrs.Brown. 此句whom引导定语从句，代指先行词the lady，在从句中作宾语。也可用that引导即“The lady that we saw this morning is Mrs.Brown.” 例：As is known to all,China is a large country. As is know to all是个很常用的表达方式，这也是的定语从句，只不过它的位置不像别的定语从句在先行词的后面，本句as代指主句的含义“中国是个大国“。 As是一个特殊的引导词，引导定语从句时为代词。不像其他的
定语从句精讲精练 (一)关系代词的选用 1.首先找准先行词，并弄清先行词是人还是物。 2.必须弄清先行词在从句中所作的成分，这是选择关系代词的关键。 ⑴先行词指人，并在从句中作主语、宾语，关系代词用who/that; as； ⑵先行词指物，并在从句中作主语、宾语，关系代词用that/which/as; ⑶先行词指人、指物、并在从句中作表语，关系代词用that/as/who/which; ⑷先行词指句子，并在从句中作主语、宾语、表语，关系代词用which,as； ⑸先行词是“时间名词”，如在从句中作主语、宾语，关系代词用which/that/as; 作状语，用when; ⑹先行词是“地点名词”，如在从句中作主语、宾语，关系代词用which/that/as; 作状语，用where; ⑺先行词是reason ，如在从句中作主语、宾语，关系代词用which/that/as; 作状语，用why; ⑻先行词指人、物，并在从句中作定语，用whose,指物时，可与 the＋名词＋of which互换； ⑼先行词是way,manner等词，关系代词用that，in which,亦可省略； ⑽关系代词前有介词时，关系代词用which(指物),who(指人)。 3.选择关系代词时应注意的几点： ⑴that 不能放在介词之后作宾语， which,who则可以，如介词在句子后面时，也可用that,也可省略。 This is the room in which we lived last year.=This is the room we lived in last year.这是我们去年住过的房间。 ⑵that不能引导非限定性定语从句，其它关系词可以，引导非限定性定语从句的关系代词不可省略。 We walked down the village street,where they were having market day.我们沿着村子的大街走去，村民们正在那里赶集。 ⑶as 引导定语从句，主句中的先行词常被such，the same或 so 修饰。the same...as 指“相类似的人（物）”，而 the same... that 指“同一人（物）。 We will give you such information as will help you in your work.我们将向你们提供有助于你们工作的资料。 This is the same bag as I lost yesterday.这个包和我昨天丢失的那个一样。（相似性）
一次性通过市政实务经验分享 建造师考试=90%实力+10%运气 个人情况简介：03年中专毕业，07年成人专科，13年网教专升本，在某国企工作8年，搞施工测量，其实中专学的是**工程，因为到单位时候，安排搞测量，就去了，那个时候不懂，后来才明白，没人愿意搞施工测量，各种委屈也许测量同行体会更深些，10年跳出施工单位，转作测量监理至今，搞测量时候傻咧咧的，根本不知道看书学习，其实那个时候空闲时间还多，做监理后才接触了更多测量以外的东西，明白了证书的重要性。 另本人文笔不好，如果您觉得啰嗦过多，可以挑着看，下面简单谈下我2016年一级建造师市政公用专业考试的所经过的学习经过。首先之所以选择市政公用专业是因为他挂靠费用高，其次是盲目跟风，因为身边的同事都考这个专业。 一、做好充分的准备工作 1、心理准备 选择市政公用专业，就意味着你要付出，首先在选择专业时，就要做好强大的心理准备。做到什么程度呢，要有承受住戒网5-6个月的心理准备，包括手机上网和无线上网，以安心复习；还要有当年中考或者高考前夕学习的尽头。然后作为80后大军的一员，做到这点比较难，那就需要自己创造条件。 2、课件书本准备 实务课本也可在买一个正版的，一盗一正，用起来顺手，正版的
的确质量好些，经得起看。我的盗版书，一本看成两本那么厚了。 经济梅世强老师经济有此老师一人足矣但他对第三章划的内容讲解不是很多，近几年第三章考试内容有扩大的成分且建设部13年出了新的貌似83号文，与书上的很大不同，用旧书的朋友要特别注意，第三章要等新书，旧书内容可以不看。 管理顾永才老师如果不够加上肖国祥老师一般也够了 法规有一定基础的，比如考过2建的，直接陈印大师一人的课件足矣。没有一定基础的建议王竹梅老师+陈印老师（王竹梅老师的，我听了几节课，讲解太细致，所以没听） 之所以推荐大师，是因为大师讲课不是划书的，他们讲课幽默诙谐，让你感到轻松，尤其是陈印大师，初次考一建一定要先把陈印老师的第一第二节课答题通用方式听两遍以上，好处多多。 以上推荐大师，都是考友近10年推荐的，具有强烈的可信任性，和可行性。 下面说说专业科目，市政公用包含了近10个专业，出题范围极光极大，就算降低分数线或者放水增加考分，其困难程度在今后的考试中依然独占鳌头。 因为建造师考试，重点无论过多久，依然是重点，必须年年考，或者隔年靠，非重点书上讲解的再多依然不会考的，这个考试不同于其他考试，不是说今年考了明年就不考了，切记不是这个概念。 市政实务推荐陈明老师，听他考试近三年的课件，其次是曹铭明（曹老师的课件我没有，因为工地没网，我没下载，是考友推荐的）
定语从句 一.定义： 定语：定语可以由形容词、代词、数词、名词、分词、不定式、介词短语等来担任，修饰名词或代词。定语从句：用来修饰主句中一个词或词组的句子，称为定语从句。 要素：先行词（主句中被修饰的词）；关系代词副词（从句的引导词） 考纲要求：对于定语从句要求掌握以下内容： 1. 引导限制性定语从句的关系词 2. 引导非限制性定语从句的关系词 3. 限制性定语从句与非限制性定语从句的区别 4. 介词+关系代词用法 5. 不定代词数词+of which / wh引|r导的非限制性定语从句及其结构与并列句的判断 6. 关系词间的转换及选用 认识: Handsome boys = the boys who are handsome Beautiful flowers = the flowers which are beautiful 二.限制性定语从句： 限制性定语从句：这种从句和主句的关系十分密切，写时不可用逗号分开。限制性定语从句 常由that, which, who, whom, whose, when, where, why,a引导。 （一）关系词：关系代词和关系副词 1. 关系代词引导的定语从句 关系代词:that, who, whom, which, whose 用法： （1）.限制性定语从句中只能用that不用which的情况:
a. 先行词为不定代词everything, anything, nothing ,something , all, much, little, none, few, some 等不定代词修饰时用that。 He did everything that he could to help us. There is little that I can do for you. b. 先行词前有形容词最高级、序数词修饰时用that。 This is the best book that I 've ever read. This is the first thing that I want to say. c. 当先行词是one of, the one, 或者先行词被all, every, no, some, any, little, much, the only, the very, the same, the last, few, jus等修饰时用that。 It is the one that you want. All the things that we can do is to give you some advice. It is the only thing that I like to do. d. 当先行词包含了指人和物两方面的含义时用that。 They talked about the things and persons that they knew in the school. e. 在疑问词who、which、what开头的句子中，用that Who is the man that spoke to you at the gate? Which is the star that is nearest to the earth? f. 先行词是主句的表语且关系代词在从句中作表语时用that。 He is not the boy that he used to be. China is no longer the country that it used to be. (2) .限制性定语从句中只用which不用that的情况： a. 在非限制性定语从句中 She didn 't pass the exam, which made her sad. b. 关系代词前有介词时 This is the room in which Lu Xun lived. c. 先行词本身是that The clock is that which tells the time.
关系代词as和which 引导的定语从句 as和which引导非限制性定语从句，有相同之处也有不同之处。具体情况是：1. As和which都可以在定语从句中做主语或者宾语，代表前面整个句子。 He was honest, as/which we can see. as 引导非限制性定语从句，可放在主句之前，或者主句之后，甚至可以切割一个主句；which引导的非限制性定语从句只能放在主句之后。另外，as有“正如……，正像……”的意思 which 指代整个句子不可置于句首只能位于主句后。 1. They d idn’t come to school on time, which made the teacher angry. 2. The sports meeting was put off, which astonished (吃惊）us greatly. 3. His father died last year, which made it impossible for him to go to school. 4. He didn’t pass the exam, which disappointed his parents. as 引导定语从句，位置灵活，可位于句首、句中和句末。 As we all know, China is a developing country. The number of the visitors, as we had expected, was over 200. China is a great country with a long history, a s is known to all. 注意:当主句和从句存在逻辑上的因果关系时,主句与从句有因果或并列，从句谓语动词是“系动词+adj" 使用which Our class has won the volleyball match, which is inspiring. Tom suddenly fell ill, which made us sad. Tom突然病倒，这使得我们很伤心。Which引导的非限制性定语从句在从句中做主语，其代指整个主句，主从句的关系是因果关系，因为他的病，所以我们伤心。 The road was too slippery, which caused lots of accidents. 路太滑了，以至于引起了很多事故。which引导的非限制性定语从句在从句中做主语，其代指整个主句，主从句的关系是因果关系，因为路滑，所以出事。 (1) As is known to all, China is a developing country. (2) He is from the south, as we can see from his accent. (3) John, as you know, is a famous writer. (4) He has been to Paris more t han several times, which I don’t believe. (5) Tom was always late for school, which made his teacher angry.
定语从句专项讲解与练习 定语从句的定义：从句作定语，修饰名词、代词，这样的从句叫定语从句。 定语从句所修饰的词叫先行词。定语从句作定语放在先行词的前面。 如果要表达:我喜欢那个漂亮的女孩。I love the pretty girl. 如果要表达：那个喜欢我的女孩。只能借助于定语从句the girl who loves me. 其中the girl即为定语从句的先行词，而who即为定语从句的关系词。 指人：who、whom 关系代词指物：which、as （作主宾表）指人和物:that,whose 关系词表时间：when 关系副词表地点：where （作状）表原因：why 1、who 指人，who在从句中当主语。 He who has not reached the Great Wall isn’t a true man. 不到长城非好汉。 The teacher ___________spoke at the meeting just now is having a rest in his office. 中文意思：____________________________________________________________________ ?作主语时不能省略，作宾语时可省略。 2、whom 指人，是who的宾格形式，在从句中作宾语，前面没有介词时，可用who/that来代替，也可省略。The girl ___________________ I like isn’t here now. 中文意思：____________________________________________________________________ The doctor with ________________she went to the United States last month is very famous. 中文意思：____________________________________________________________________ The person ___________________ you met yesterday is our Chinese teacher. 中文意思：____________________________________________________________________ 3、whose 指“谁的”，或“某物的”，在从句中作修饰词。 whose和它所修饰的名词在定语从句中可作主语及动词或介词的宾语。 The girl ___________father is a doctor is our classmate. You’re the only one ____________ advice he might listen to. 中文意思：____________________________________________________________________ I’d like a room _______________window looks out over the sea. 中文意思：____________________________________________________________________ 4、that 在从句中作主语或宾语，既可以指人又可以指物；作宾语时可以省略。 She is the very person (that) I want to see at once. 中文意思：____________________________________________________________________ A plane is a machine_____________ can fly. 中文意思：____________________________________________________________________

高中英语定语从句讲解及练习 定语从句是高中重点知识，也是高考常考点，大家也不容易掌握，这篇文章主要教你关系代词引导的定语从句 关系副词引导的定语从句判断关系代词与关系副词限制性和非限制性定语从句等内容，有例题讲解定语从句在句中做定语，修饰一个名词或代词，被修饰的名词词组或代词即先行词。定语从句通常出现在先行词之后，由关系词（关系代词或关系副词）引出。 关系代词有：who, whom, whose, that, which等。 关系副词有：when, where, why等。 18.1 关系代词引导的定语从句 关系代词所代替的先行词是人或物的名词或代词，并在句中充当主语、宾语、定语等成分。关系代词在定语从句中作主语时，从句谓语动词的人称和数要和先行词保持一致。 1）who, whom, that 这些词代替的先行词是人的名词或代词，在从句中作主语和宾语。例如： Is he the man who/that wants to see you? 他就是你想见的人吗？（who/that在从句中作主语） He is the man whom/ that I saw yesterday. 他就是我昨天见的那个人。（whom/that在从句中作宾语） 2）whose 用来指人或物，（只用作定语, 若指物，它还可以同of which互换）。例如： They rushed over to help the man whose car had broken down.那人车坏了，大家都跑过去帮忙。 Please pass me the book whose （of which）cover is green.请递给我那本绿皮的书。 3）which, that所代替的先行词是事物的名词或代词，在从句中可作主语、宾语等。例如： A prosperity which / that had never been seen before appears in the countryside. 农村出现了前所未有的繁荣。（which / that在句中作宾语） The package （which / that）you are carrying is about to come unwrapped. 你拿的包快散了。（which / that在句中作宾语） 18.2 关系副词引导的定语从句 关系副词可代替的先行词是时间、地点或理由的名词，在从句中作状语。 1）关系副词when, where, why的含义相当于\"介词+ which\"结构，因此常常和\"介词+ which\"结构交替使用。例如： There are occasions when （on which）one must yield.任何人都有不得不屈服的时候。 Beijing is the place where（in which）I was born.北京是我的出生地。 Is this the reason why （for which）he refused our offer?这就是他拒绝我们帮助他的理由吗？ 2）that代替关系副词，可以用于表示时间、地点、方式、理由的名词后取代when, where, why和\"介+which\"引导的定语从句，在口语中that常被省略。例如： His father died the year （that / when / in which）he was born.他父亲在他出生那年逝世了。 He is unlikely to find the place （that / where / in which）he lived forty years ago. 他不大可能找到他四十年前居住过的地方。 18.3 判断关系代词与关系副词 方法一：用关系代词，还是关系副词完全取决于从句中的谓语动词。及物动词后面无宾语，就必须要求用关系代词；而不及物动词则要求用关系副词。例如： This is the mountain village where I stayed last year. 这是我去年呆过的山村。 I'll never forget the days when I worked together with you.我永远不会忘记与你共事的日子。 判断改错： （错）This is the mountain village where I visited last year. （错）I will never forget the days when I spent in the countryside. （对）This is the mountain village （which）I visited last year. （对）I'll never forget the days （which）I spent in the countryside. 习惯上总把表地点或时间的名词与关系副词where, when联系在一起。此两题错在关系词的误用上。 方法二：准确判断先行词在定语从句中的成分（主、谓、宾、定、状），也能正确选择出关系代词/关
