B 用另一种方式 in another way in 可以省略 by the way 是顺便问， 没有这个说法
这几个都是考察虚拟语气的用法。must have done 表示对过去事实的肯定推测。把句子翻译过来答案就出来了。 这是一个第三人在陈述这件事。 译文：独自行走在黑暗的街上，john害怕他会死。他呢喃这说：“他一定是叫了George跟他一起走的。”（这里的“他”是除了john，George外的第三人） 懂把。
一、自我分析 1、分析自己的学习特点，同学们可以仔细回顾一下自己的学习情况，找出学习特点。各人的学习特点不一样：有的记忆力强，学过知识不易忘记；有的理解力好，老师说一遍就能听懂；有的动作快但经常错；有的动作慢却很仔细。 2、分析自己的学习现状，一是和全班同学比，确定看自己数学成绩在班级中的位置，还常用＂好、较好、中、较差、差＂来评价。二是和自己数学成绩的过去情况比，看它的发展趋势，通常用＂进步大、有进步、照常、有退步、退步大＂来评价。 二、确定目标 学习目标是学生学习的努力方向，正确的学习目标能催人奋进，从而产生为实现这一目标去奋斗的力量。没有学习目标，就象漫步在街头不知走向何处的流浪汉一样，是对学习时光的极大浪费。 学习目标要具有适当、明确、具体的特点。适当就是指目标不能定得过高或过低，过高了，最终无法实现，容易丧失信心，使计划成为一纸空文；过低了，无需努力就能达到，不利于进步。要根据自己的实际情况提出经过努力能够达到的目标。 三、安排时间 合理要找出每天学习的最佳时间，如有的同学早晨头脑清醒，最适合于记忆和思考；有的则晚上学习效果更好，要在最佳时间里完成较重要的学习任务。高效要根据事情的轻重缓急来安排时间，一般来说，把重要的或困难的学习任务放在前面来完成，因为这时候精力充沛，思维活跃，而把比较容易的放稍后去做。 一天中供自己安排的时间基本上分为四段：早上起床到上学，上午放学到下午放学，下午放学到吃晚饭前，吃晚饭后到睡觉。同学们主要应在这四段时间里统筹安排自己的学习生活内容。 /iknow-pic.cdn.bcebos.com/d8f9d72a6059252d939dd3783b9b033b5ab5b9c0"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/d8f9d72a6059252d939dd3783b9b033b5ab5b9c0?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/d8f9d72a6059252d939dd3783b9b033b5ab5b9c0"/> 扩展资料： 在进行时间安排时，还要注意以下两点： 1、要突出重点也就是说，要根据地自我分析中提出的学习标点或比较薄弱的学科在时间上给予重点保证。 2、要有机动时间，计划不要排太满太紧，贪心的计划是难以做到的。 定了计划，一定要实行，不按计划办事，计划是没有用的。为了使计划不落空，要对计划的实行情况定期检查。可以制定一个计划检查表，把什么时间完成什么任务达到什么进度，列成表格，完成一项，就打上＂√＂。
一、在校学习 大学培养综合性人才是大多数人获取知识的主要途径。从幼儿园、小学、中学、高中到大学（本科生、硕士、博士），这条道路是开放的，漫长的，实现了无数学生的梦想。如果是这样，这条路应该是学习的首选。 二、实践学习 在做事的时候，学会做事通常是很难的，因为当我们埋头做事时，我们并没有形成一个系统。只有从做事的角度来学习，才能实现持续而系统的成长。 三、阅读学习 阅读的好处是显而易见的。它比其他方式更简单、更便宜。此外，阅读是高度系统的。如果你随意拿起一本书，作者会系统地告诉你一些事情。这是书籍的固有特征。 四、向他人学习 善于发现别人的长处，从别人没有的东西中学到很多东西，以及从别人那里看出我们的缺点，弥补它们是很可怕的。如果你知道你是谁，除非你知道你是谁，否则你永远不会输掉你的战斗。 五、综合性学习 合理运用不同的学习方式，具体分析具体情况。技能知识更具动手性，接触不熟悉的领域可以先咨询专家。进一步的信息可以通过互联网搜索，知识体系主要通过阅读形成。 参考资料来源：百度百科-在学校期间 百度百科-综合实践活动课程 百度百科-快速阅读 百度百科-综合学习
定语从句定语从句及相关术语 1.定语从句：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。 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。关系代词有that, which, who, whom, whose, as等；关系副词有where, when, why等。关系词常有3个作用：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。 注：关系代词有主语.宾语之分。一般whom作为宾语。 4.定语：定语用来限定、修饰名词或代词的，是对名词或代词起修饰、限定作用的词、短语或句子，汉语中常用‘……的’表示。主要由形容词担任。此外，名词，代词，数词，分词，副词，不定式以及介词短语也可以来担任，也可以由一个句子来担任．单词作定语时通常放在它所修饰的词之前，作前置定语。短语和从句作定语时则放在所修饰的词之后，作后置定语。 先行词：被定语从句修饰的名词、代词称为先行词.（一） 限定性定语从句 一、关系代词（在句中作主语、宾语或定语） 1. that既可代表事物也可代表人，which代表事物；它们在从句中作主语或宾语，that在从句中作宾语时常可省略关系词，which在从句中作宾语也可以省略。[eg：this is the book （which）you want。] 2而且，如果which在从句中作“不及物动词＋介词”的介词的宾语，注意介词不要丢掉，而且介词总是放在关系代词which的前边，但有的则放在它原来的位置 3. 代表物时多用which，但在带有下列词的句子中用that而不用which，这些词包括当先行词是anything, everything, nothing , none等不定代词时，或者是由every, any, all, some, no, little, few, much等修饰时等，这时的that常被省略 还有先行词前有序数词或形容词最高级修饰时,或先行词就是序数词或最高级时.以及先行词中既有人又有物时.还有句中前面有which时,都只能用that 4. who和whom引导的从句用来修饰人，分别作从句中的主语和宾语，whom作宾语时，要注意它可以作动词的宾语也可以作介词的宾语 5. whose是关系代词，修饰名词作定语，相当于所修饰成分的前置所有格.它引导的从句可以修饰人和物, 当它引导的从句修饰物体时, 可以与 of which 调换,表达的意思一样。 二、关系副词（在句中作状语） 关系副词=介词+关系代词 why=for which where=in/ at/ on/ ... which (介词同先行词搭配) when=during/ on/ in/ ... which (介词同先行词搭配) 1. where是关系副词，用来表示地点的定语从句。 2. when引导定语从句表示时间〔注〕值得一提的是，表示时间“time"一词的定语从句只用when引导，有时不用任何关系代词，当然也不用that引导。 By the time you arrive in London, we will have stayed there for two weeks. I still remember the first time I met her. Each time he goes to business trip, he brings a lot of living necessities, such as towels, soap, toothbrush etc。 3. 当从句的逻辑主语是some, any, no, somebody, anybody, nobody, something, anything, everything或nothing时，常用there is来引导 There is somebody here who wants to speak to you. 这里有人要和你说话。 （二）非限定性定语从句 非限定性定语从句的作用是对所修饰的成分作进一步说明，通常是引导词和先行词之间用逗号隔开，将从句拿掉后其他部分仍可成立 1. which引导的非限定性定语从句来说明前面整个句子的情况或主句的某一部分 2.当先行词是专有名词或物主代词和指示代词所修饰时，其后的定语从句通常是非限制性的，例如： Charles Smith, who was my former teacher, retired last year. 查理·史密斯去年退休了，他曾经是我的老师。 My house, which I bought last year, has got a lovely garden. 我去年买的的那幢房子带着个漂亮的花园。 This novel, which I have read three times, is very touching. 这本小说很动人，我已经读了三遍。 3.非限制性定语从句还能将整个主句作为先行词, 对其进行修饰, 这时从句谓语动词要用第三人称单数，例如： He seems not to have grasped what I meant, which greatly upsets me. 他似乎没抓住我的意思，这使我心烦。 Liquid water changes to vapor, which is called evaporation. 液态水变为蒸汽，这就叫做蒸发。 4. 有时as也可用作关系代词 5. 在非限定性定语从句中，不能用关系副词why和关系代词that，而用who, whom代表人，用which,whose代表事物.； [编辑本段]（三）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. 在踢足球的男孩们是一班的. (2) Yesterday I helped an old man who lost his way. 昨天，我帮助了一个迷路的老人. 2. whom指人，在定语从句中充当宾语，常可省略。（注：who和whom已无太大区别，基本上可以通用。唯一区别是who可以做主语而whom不可以。） (1) Mr. Liu is the person (whom) you talked with on the bus. 刘先生就是在公交车上和你聊天的那个人. (2) Mr. Ling is just the boy whom I want to see. 凌先生恰巧就是我想见的那个男孩. (3) The man who/whom you met just now is my friend. 你刚刚见到的那个人就是我的朋友. 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。 如果在从句中做宾语,就用whom或who.比如: He is the man whom/who I talk to. 他就是那个和我聊天的男人. 如果是在从句中作主语就只能用who.比如: He is the man who has an English book. 他就是那个有英语书的男人. 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. 足球是大多数男孩都喜欢的游戏. (2) This is the pen (which) he bought yesterday. 这是他昨天刚买的钢笔. 4. that指人时，相当于who或者whom；指物时，相当于which。 在定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 color is yellow? (6) Do you like the book the color of which is yellow? [编辑本段]（四）注意 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. = The school in which he once studied is very famous. (2) Tomorrow I will bring here a magazine (that/which) you asked for. = Tomorrow I will bring here a magazine for which you asked. (3) We’ll go to hear the famous singer (whom/that/who) we have often talked about. = We’ll go to hear the famous singer about whom we have often talked. 注意：1. 含有介词的动词短语一般不拆开使用，如：look for, look after, take care of等 T This is the watch which/that I am looking for. (T＝正确) F This is the watch for which I am looking. (F＝错误) 2. 若介词放在关系代词前，关系代词指人时用whom，不可用who或者that；指物时用which，不能用that；关系代词是所有格时用whose (1) The man with whom you talked is my friend. (T) The man with that you talked is my friend. (F) (2) The plane in which we flew to Canada is very comfortable. (T) The plane in that we flew in to Canada is very comfortable. (F) 3. “介词+关系代词”前可有some, any, none, both, all, neither, most, each, few等代词或者数词 (1) He loved his parents deeply, both of whom are very kind to him. (2) In the basket there are quite many apples, some of which have gone bad. (3) There are forty students in our class in all, most of whom are from big cities. 关系代词 关系代词（一般情况下）that 可用who ,whom 和which在从句做主语，谓动词的宾语，但是不能做介词的宾语 which指物，在从句中作主语，谓语或宾语； who在从句中作主语； whom在从句中宾语； where在从句中修饰表地点的名词，做地点状语； when在从句中通常修饰表时间的名词，做时间状语； why在从句中做原因状语，先行词通常是"reason" 有时why也可用for+which代替。 例：A doctor is a person who looks after people's health. ______ _ _____ _____________________ 主语 谓语 先行词 从句 |________________________| 定语从句修饰先行词 （五）关系副词引导的定语从句 1. when指时间，在定语从句中做时间状语 (1) I still remember the day when I first came to the school. (2) The time when we got together finally came. 2. where指地点，在定语从句中做地点状语 (1) Shanghai is the city where I was born. (2) The house where I lived ten years ago has been pulled down. 3. why指原因，在定语从句中做原因状语 (1) Please tell me the reason why you missed the plane. (2) I don’t know the reason why he looks unhappy today. 注意：关系副词引导的从句可以由“介词+关系代词”引导的从句替换 (1) The reason why/ for which he refused the invitation is not clear, (2) From the year when/in which he was going to school he began to know what he wanted when he grew up. (3) Great changes have taken place in the city in which./where I was born. [编辑本段]（六）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。不及物动词后面无宾语，就必须要求用关系副词或者是介词加关系代词；而及物动词后接宾语，则要求用关系代词。例如： This is the mountain village where I stayed last year. I'll never forget the days when I worked together with you. 判断改错（注：先显示题，再显示答案，横线；用不同的颜色表示出。） （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/关系副词。例1. Is this museum ___ you visited a few days ago? A. where B. that C. on which D. the one 例2. Is this the museum ____ the exhibition was held? A. where B. that C. on which D. the one答案： 例1 D，例2 A 例1变为肯定句： This museum is ___ you visited a few days ago.例2变为肯定句： This is the museum ___ the exhibition was held. 在句1中，is后应跟表语，只有the one可以，而后面的you visited a few days ago则做one的定语从句。 而句2中, 主、谓、宾俱全，从句部分为句子的状语表地点，既可用副词where，又因 in the museum词组，可用介词in + which 引导地点状语。而此题中，介词on 用的不对，所以选A。 关系词的选择依据在从句中所做的成分，先行词在从句中做主、定、宾语时，选择关系代词 (who, whom, that, which, whose)； 先行词在从句中做状语时，应选择关系副词 ( where 地点状语，when 时间状语，why 原因状语) 。 [编辑本段]（七）介词+关系词 1）介词后面的关系词不能省略。 2）that前不能有介词。 3） 某些在从句中充当时间，地点或原因状语的"介词+关系词"结构可以同关系副词when ,where和why 互换。 This is the house in which I lived two years ago. This is the house where I lived two years ago. Do you remember the day on which you joined our club? Do you remember the day when you joined our club? This is the reason why he came late. This is the reason for which he came late. （八）先行词和关系词二合一 1)Whoever spits in public will be punished here. (Whoever 可以用 anyone who 代替) 2)The parents will use what they have to send their son to technical school. (what 可以用all that代替) 但这两句句子已经不是定语从句了，是名词性从句。因为定语从句一定要有先行词，而名词性从句没有。将“Whoever”、“what”分别用“Anyone who”、“all that”代替后，才是定语从句，先行词分别是“Anyone”、“all”。 [编辑本段]（九）as,which引导的非限制性定语从句 由as, which 引导的非限定性定语从句，as和which可代整个主句，相当于and this或and that。As一般放在句首，which在句中。 As we know, smoking is harmful to one's health. The sun heats the earth, which is very important to us. 典型例题 1）Alice received an invitation from her boss, ___came as a surprise. A. it B. that C. which D. he 答案C. 此为非限定性从句，不能用 that修饰，而用which.，it 和he 都使后句成为句子，两个独立的句子不能单以逗号连接。况且选he句意不通。 2）The weather turned out to be very good, ___ was more than we could expect. A. what B. which C. that D. it 答案B。 which可代替句子，用于非限定性定语从句，而what不可。That 不能用于非限定性定语从句，it不为连词，使由逗号连接的两个句子并在一起在英语语法上行不通。 3）It rained hard yesterday, ____ prevented me from going to the park.. A. that B. which C. as D. it 答案B. as 和which在引导非限制性定语从句时，这两个关系代词都指主句所表达的整个意思，且在定语从句中都可以作主语和宾语。但不同之处主要有两点： (1） as 引导的定语从句可置于句首，而which不可。 (2） as 代表前面的整个主句并在从句中作主语时，从句中的谓语必须是系动词；若为行为动词，则从句中的关系代词只能用which.。 在本题中，prevent由于是行为动词，所以正确选项应为B。 As 的用法例 1. the same… as；such…as 中的as 是一种固定结构, 和……一样……。 I have got into the same trouble as he (has). 例2. as可引导非限制性从句，常带有'正如'。 As we know, smoking is harmful to one's health. As is known, smoking is harmful to one's health. As是关系代词。例1中的as作know的宾语； 例2中，它充当从句的主语，谓语动词know要用被动式。 一、“as / which” 特殊定语从句的先行成分 1. 形容词或形容词短语作先行成分, 具有形容词意义的介词短语也可以充当先行成分，如： My grandmother’s house was always of great importance to me, as my own is. 在一定的语言环境里，有些名词可以具有形容词的性质。这些名词主要是那些表示人的身份、职业、状态的名词。值得一提的是，在这些具有形容词性质的名词之后，引导定语从句的关系代词不能用who / whom. 2. 动词短语先行成分 这种动词短语既可是限定形式也可是非限定形式。如果是动态动词短语，它们在从句中就一般有限定或非限定形式的替代动词do和as / which一起代替。do可以出现，也可以不出现，但不能用其它动词代替。 3. 句子作先行成分 这句子可以是整个主句也可以只是主句中的一个从句。有时是连续几个句子，有时甚至可以是一个完整的故事。 二、“as/which”特殊定语从句在句中的位置 由于先行成分的构成成分不同，“as/which”特殊定语从句在句中的位置有以下几种情况： 1. 形容词做先行成分时：形容词或形容词短语（含具有形容词性质的名词）作先行成分，“as / which”特殊定语从句置于先行成分之后。 2. 动词短语作先行成分时：动词短语作先行成分时，“as / which”特殊定语从句置于先行成分之后。但是，当从句中含有表示主观意志的插入成分时，“as”特殊定语从句可以移至句子之首。 3. 句子作先行成分时：“as”特殊定语从句的位置较灵活，可以置于先行成分之前、之中或之后。但如果先行成分是直接引语，“as”特殊定语从句多在先行成分之前。如果先行成分是否定句，“as”特殊定语从句与否定词的相对位置不同可以使它产生不同的意义。由于“as”特殊定语从句具有这一特点，所以有时它的位置不能随便移动。在非正式的文体里，“which”特殊定语从句可以出现在先行成分之中。 三、“as/which”特殊定语从句的语义功能 一般说来，as与which的语义功能相同，可以相互替换。但先行成分为句子时，它们的语义功能则有差异。 1. 表示结果 表示结果的特殊定语从句与其先行成分之间存在着一定的因果关系，从句中往往使用有结果意义的词，如动词result, make, enable, cause和形容词interesting, surprising, delightful, disgraceful等。 2. 表示评注 表示评注的特殊定语从句对其先行成分所述事实的正确性有肯定的倾向，它通常与那些表示客观事实，普遍真理或某种习性的先行成分连用；从句中则常用一些表示“合乎自然规律”、“众所周知”或“经常发生”等意义的词语，如natural, known to all, usual等。 3. 有无状语意义 “as”特殊定语从句具有状语意义（主要是方式状语意义），而“which”特殊定语从句则无状语意义。“as”特殊定语从句的状语意义要求它在语义上与其先行成分的语义保持一致，“which”特殊定语从句则不受这种限制。 四、关系代词as与which的句法功能 1. as / which 在特殊定语从句中作主语。 as作主语时，谓语动词常为连系动词（主要是be, seem），主语补语为usual、 a rule、 a matter of fact等时，系动词be习惯经常省略。行为动词作“as”特殊定语从句的谓语时一般用于被动语态（其中助动词be常略），不及物的行为动词在“as”特殊定语从句中作谓语的极少，常见的有happen一词。如： Freddie, as might be expected, was attending the conference. Which作主语时，谓语动词不限，主语被动皆可，只是谓语动词为被动语态时助动词be省略。 2. as和which都可以在特殊定语从句中宾语。 3. as和 which在特殊定语从句中作补语。如： We thought him a gentleman, as/which he could never be. “as”特殊定语从句中可以主谓倒装，“which”从句中则不能主谓倒装。 如果先行成分不是主语补语或宾语补语，关系代词用which而不用as。如： He talked like a native, which/as he hardly was. 4. which在特殊从定语句中作定语。 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. （十）关系代词that 的用法 (1)不用that的情况 (a) 在引导非限定性定语从句时。 (错)The tree, that is four hundred years old, Is very famous here. (b) 介词后不能用。 We depend on the land from which we get our food. We depend on the land that/which we get our food from. (2) 只能用that作为定语从句的关系代词的情况 (a) 在there be 句型中，只用that，不用which。 (b) 在不定代词，如：anything, nothing, the one, all, much, few, any, little等作先行词时，只用that，不用which。 (c) 先行词有the only, the very,the same,the last,just修饰时，只用that。 (d) 先行词为序数词、数词、形容词最高级时，只用that。. (e) 先行词既有人，又有物时。 (f) 先行词指物，在主句中作表语时． (g) 为了避免重复． (h)先行词是the way时 举例： Is this the book that you borrowed in the library? 这是你在图书馆借的那本书吗？ Who that break the window should be punished． 谁打碎了窗户都要受到惩罚． All that is needed is a supply of oil. 所需的只是供油问题。 Finally, the thief handed everything that he had stolen to the police. 那贼最终把偷的全部东西交给了警察。
定语从句(Attributive Clauses)在句中作定语，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, that, which, whose 关系副词有：when, where, why 1. 指人：who, whom, that Is he the man who/that wants to see you? (who/that在句中作主语，不能省略。） He is the man (whom/that) I saw yesterday.(whom/that在从句中作宾语，可以省略。） 2. 指物：which, that The bank which/that was opened last week is a modern one.(which/that在句中作主语，不能省略。) The briefcase (which/that) you are carrying is heavy. (which/that在从句中作宾语，可以省略。) 3. 所有格：whose (指物时可以同of which互换,指人和of whom 互换) They rushed over to help the man whose car （the car of whom)had broken down. Please pass me the book whose cover(of which the cover/the cover of which) is green. 注：根据句子意思和结构需要，必须使用适当的介词. 介词后关系词不能省;介词后不能用that: Do you know the boy (whom/that) I talked to just now? =Do you know the boy to whom I talked just now? The palace to which I often pay a visit was built in the 17th century. Yesterday I bought a pen with which I can write my composition. 关系副词：when, where, why (相当于“介词＋which”结构） 1. when 在从句中作时间状语 I still remembered the day (that/which) we first met on. (正) I still remembered the day on that we first met. (误) I still remembered the day on which/ when we met. (正) 比较：I still remember the day (that/which) we spent together. 2. where在定语从句中作地点状语 Shanghai is the place where /in which I was born. Shanghai is the place (which/that) I was born in. 比较：Shanghai is the place (which/that) I visited last year. 3. Why在定语从句中作原因状语 Is this the reason why /for which he refused our offer? 比较： This is the reason (that/which) I gave to my teacher. 所以：判断使用关系代词或关系副词不能光看先行词是否是表示时间,地点,原因的名词，必须分析从句谓语动词与先行词的逻辑关系。如果关系词在从句中作状语则分别用when,where或why 等关系副词；如作主语或宾语，则仍用关系代词which或that。 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，去掉不会影响主句的意思，它与主句之间通常用逗号分开，如： This is the house which we bought last month.(限制性) The house, which we bought last month, is very nice.(非限制性) She has a son who is a doctor. 她有一个当医生的儿子。 She has a son, who is a doctor. 她有一个儿子，是个医生。 2. 由as, which 引导的非限定性定语从句，as和which可代整个主句，which相当于and this或and that。1)As一般放在句首，which在句中。2) as也可在句中往往和see,know,expect等词连用。 a. He seemed not to have grasped what I meant, which/and this greatly upsets me. b. The sun heats the earth, which/and this is very important to us. c. As was expected, the beautiful girl married a handsome boy. d. As we all know, smoking is harmful to one's health. e.He must be from Africa, as can be seen from his skin. 3. 非限制定语从句中of which/of whom常用于基数词或some, most, all, none, either,neither等词之后，而不用whose: These books, two of which I have read, are interesting. The teachers speak highly of the set of workbooks, all of which have come out. The audience, most of whom were college students, enjoyed the concert. 注：关系代词that和关系副词why不能引导非限制性定语从句。 定语从句中若先行词前有the same, such作修饰语，通常用as作关系代词。 He used such expressions as he could find in the texts. They stayed for the night in the same room as they had once rented. 定语从句中若先行词前有比较级修饰，通常用than作关系代词。 The boy has eaten more food than is good for health. Never give him more money than is necessary. such…as和such..that such…as定语从句, as在从句中可以作主语,宾语,表语；such…that引导结果状语从句，that不充当任何成分，只起到连接作用，如： They talked in such simple language as children could understand. They talked in such simple language that children could understand it. the same…as和the same…that 两者都可以引导定语从句，但the same…as指两件事物,而the same…that指同一件事物： He is using the same pen as I did 10 years ago. 他用的这支钢笔和我十年前用的那支一个样。 He is using the same pen that I did 10 years ago. 他用的这支钢笔就是我十年前用的那支。 只能用that作关系代词的情况 在不定代词anything, nothing, the one, all, much, any, few, little等作先行词指物时 Is there anything that you don’t understand? All that glitters is not gold. 先行词有the only, the very修饰物时 This is the only book that I want. He is the very person that/who robbed me of my purse on that day.（修饰人不一定） 先行词为形容词最高级时 This was the most touching movie of this year that made numerous people cry. 先行词既有人又有物时 For hours we were talking about the people and places that interested us. 为避免用词的重复 Who is the man that is making a speech to the students? 6) 先行词前有序数词或the last修饰时 This is the first novel (that) I have read. Going to the theatre is the last thing (that) I want to do. 7) 关系代词在定语从句中充当表语的成分 He is not the man that he used to be. 1. way 的用法 I don’t like the way (that/in which) he speaks. The way (that/in which) you look at customers doesn’t give them a good impression. 2. the one的用法 Is this book the one (that) you are looking for? 比较：Is this the book (that/which) you are looking for? 3. one of 与the only one of 的用法 Tom is one of the students who have won the first prize. Tom is the only one of the students who has won the first prize. 比较：One of the students has won the first prize. *what是代词（即一个名词）本身其实就相当于是一个先行词，what=the thing that 做选择题先看先行词充当的成分和指人或指物，非限制或限制先排除几个错误选项然后把先行词回带到从句中在看其充当什么，如果是状语那么就是why，where，when等词了，不是就先考虑that等连词...
