用词大学英语写作大学英语写作第1页用词用词词类型词类型名词(Nouns)名词表示名称，用来命名人、地方、事物以及普通情况。有些表示特定名称名词，通常被称为专有名词，需要大写。比如：The students who graduated from Beijing University are invited to a reception hosted by Professor Smith.北京大学毕业生们被邀请参加由史密斯教授主持欢迎会。名词最主要作用是作句子主语(施动者)或宾语(受动者)。比如：The drivers need to have very quick reactions.(主语)(宾语)司机需要具备非常快速反应能力。This months trading figures show some improvement.(主语)(宾语)本月贸易统计数字表明情况有所改进。第2页用词用词词类型词类型代词代词(Pronouns)代词作用是替换名词，以防止重复。代词主要有些人称代词、物主代词以及不定代词三种。人称代词 物主代词 不定代词(部分举例)I,me my,mine anybody someoneYou your,yours anything anyhe,him his anyone someshe,her her,hers everybody fewit its everything eachwe,us our,ours everyone manythey,them their,theirs somebody all something第3页用词用词词类型词类型下面例句中使用了三种代词：If anybody wishes to volunteer his or her services as a teacher,will he or she please stand up.任何自告奋勇想当老师人，请起立。Has anyone seen my textbook?I left it on somebodys desk.有些人看到我教科书了吗？我把它放在某个人桌子上了。注意，有些不定代词变全部格时要借助于全部格()及字母s(即 s)。第4页用词用词词类型词类型除三种惯用代词外，还有以下三种代词：(1)用于提问疑问代词：who,which,whom,whose,what等。比如：“What is the color of the reference book and to whom does it belong?”参考书是什么颜色？是谁？(2)在先行词后引导从句关系代词：who,which,that,whom,whose等。比如：The student who left the new textbook on the desk that is located in our school is still looking for it.将新教科书遗忘在我们学校书桌上学生还在寻找它。第5页用词用词词类型词类型(3)指代事物指示代词：these,those,this,that等。比如：Where did you get those?Ive been looking for some shoes like that.你在哪儿买那双鞋子？我一直在找那样鞋子。注：当指示代词后紧跟名词时，它能够起形容词作用。如：these cars,that house,this theory,those students。第6页用词用词词类型词类型动词动词(Verbs)动词是句子中心，它使句子感人真切，富有生命力。实际上，没有动词就写不成句子，因为它在主语和宾语之间起着不可或缺连接作用。比如：The company is promoting its new products.企业正在推销其新产品。He was promoted to the manager.他被提拔为经理。因为动词执行或接收某一行为动作，反应某一情况或事件，所以，动词是使一组词表示意思关键。比如：第7页用词用词词类型词类型The table lamp was knocked over by our cat while he was playing with the cord.我们家猫在玩儿细绳时将台灯打翻了。We should make major efforts to restore and protect forests and land,slow down population growth,relieve debts of the developing countries,raise energy efficiency and develop renewable energy sources,such as water power and solar energy.我们应该大力恢复保护森林和土地，减缓人口增加速度，减轻发展中国家债务，提升能源效率，开发可再生能源，如水力、太阳能等。第8页用词用词词类型词类型形容词形容词(Adjectives)形容词是用来修饰(描述、限制、连接)名词或代词，回答由which,how many,how much和what kind等疑问词提出问题。有些修饰语如冠词a,an,the等，回答“哪一个”这类问题。形容词通常位于名词、代词之前。比如：The weary traveler,lonely and forlorn,approached the outskirts of the deserted city.疲惫不堪、孤苦伶仃旅行者向这座荒废城市边界走近。第9页用词用词词类型词类型And most of all,“Lord Williams”bought the run-down Gordon Arms Hotel and totally restored it,transforming it from a mess into a glorious first-class hotel with 30 handsomely furnished rooms,wood-paneled stairs,false bookshelves with fake leather books and an outstanding restaurant.而最主要，是威廉姆斯勋爵将年久失修戈登阿姆斯旅馆买下并完全改装，将这堆废墟变成了一座富丽堂皇一流宾馆，内有30间装修华丽房间、木质镶嵌楼梯、摆满了人造皮革装订书籍书架，还有一间高级餐厅。第10页用词用词词类型词类型副词副词(Adverbs)副词比形容词更灵活，能够修饰动词、形容词和其它副词，可位于句中任何位置。通常回答在哪儿(where)、什么时候(when)、怎样(how)以及多少(how much/many)等问题。副词不但确定形容词和其它副词确实切含义，还确定动词意义。比如：extremely unhappy极其悲伤incredibly busy忙得焦头烂额Her long fingers curl easily around my hand and I nod my head slowly,smiling.她那细长手指很轻易地就拢住了我手，我微笑着慢慢点了点头。第11页用词用词词类型词类型副词能够依据它们意思分为下面几类：(1)时间副词(2)地点副词(3)方式副词(4)程度副词(5)疑问副词(6)连接副词(7)关系副词(8)其它性质副词在写作中，我们要着重掌握以下两种副词使用方法。第12页用词用词词类型词类型连接副词连接副词(Conjunctive Adverbs)英语中疑问副词有时可用来引导从句，这时称为连接副词。在句中可引导主语从句、宾语从句、表语从句等。比如：It was a mystery how she got well so soon.她怎样痊愈得这么快是一个谜。Nobody can tell why he refused to come.没人知道他为何拒绝来。That was how they overcame the difficulty.他们就是这么克服困难。第13页用词用词词类型词类型关系副词关系副词(Relative Adverbs)关系副词主要有where,when,why等，它们都可引导定语从句。比如：We took the picture last year,when we were on holiday there.这张照片是我们去年在那里休假时照。A library is a place where we can borrow books.图书馆是我们能够借书地方。Is that the reason why you didnt take the exam?这就是你不参加考试理由吗？第14页用词用词词类型词类型介词介词(Prepositions)介词在句中也很主要，可与名词和代词组成词组，修饰主语、谓语和宾语。下面是一些常见介词：at,by,for,from,in,of,on,to,with,between,over,under,through,within等。比如：With dignity,on the bed in his house,he died in silence.躺在家里床上，他带着尊严，平静地死去。The driver had gone straight through the traffic lights and hit an oncoming car.这名司机径直闯过交通灯，撞上了一辆迎面而来汽车。第15页用词用词词类型词类型连词连词(Conjunctions)连词是必不可少，它用来连接相同句子成份，使句子保持平衡和连贯。惯用连词有以下几个：并列连词，相关连词，隶属连词等。第16页用词用词词类型词类型1并列连词并列连词(Coordinate Conjunctions)并列连词是最惯用一个连词，包含：and,but,or,nor,for,yet和so等。并列连词连接语法作用相同句子成份，如：词、词组和句子。(1)词:Bill and Frank 比尔和弗兰克tea or coffee 茶或咖啡(2)词组：on the river and over the hill 山那边，小河旁(3)从句：No one knew who he was or what he did.没有些人知道他是谁或者他做过些什么。(4)主句：The director told me the actors name,but I have forgotten it.导演告诉过我这位演员名字，不过我忘记了。第17页用词用词词类型词类型2相关连词相关连词(Correlative Conjunctions)相关连词通常成对出现，用以保持平衡和表示强调。比较主要相关连词有四对：either.or,neither.nor,not only.but/but also,both.and。比如：She is not only a portrait painter but also a concert piano player.她不不过一位肖像画家，而且是一位音乐会钢琴演奏家。She is the kind of person you either love or hate.她是那种叫你不是爱就是恨人。The equipment is neither accurate nor safe.这种设备既不准确也不安全。We were treated with both tolerance and compassion.他们对待我们既宽容又有同情心。第18页用词用词词类型词类型隶属连词隶属连词(Subordinate Conjunctions)隶属连词连接主句和从句，使用方法视隶属关系而定。常见隶属连词有：that,when,since,after,before,while,as,as soon as,till,until,because,if,though,although,以及so.that等。比如：I entered the room while Li Ming was talking with her.我进屋时，李明正和她谈话。When he finished the speech,the audience burst into applause.他讲话结束时候，听众掌声雷动。He

惯用词，按文体可分为正式用语和非正式用语。英语词汇十分丰富，一些源于拉丁语、希腊语和法语长词，多用于正式文体，如：学术性或理论性著作、政府文件、法律文书等，这就是我们日常所说“大词”。而与之相正确一些源于古英语词，普通比较短小，只有一两个音节，惯用于非正式文体，如：日常写作、会话等，这就是所谓“小词”。请看下面例子：第20页用词用词词类型词类型例例1.Nineteenth-century middle-class reformers perceived rural women as models of perfect health.Yet in the rural community,a dramatically different perspective emerged.Female agriculturalists and male reform allies clashed with male defenders of the status quo in analyzing females health and quality of life.Farm women cited gender conflict as a source of their gloomy lives.Farm daughters第21页用词用词词类型词类型wanted to quit the farm and experienced a rise in expectations.To improve farm womens physical and mental well-being and to stem the home-leaving tide,agricultural reformers promoted drastic changes in farm life.Based on womens private and published writings,farm journals,medical and agricultural society papers,and material culture,this study indicates that the rural-urban dichotomy in health advanced by cultural thinkers and historians jarred with farm womens own health.第22页用词用词词类型词类型例例2.You have your tension.Sometimes you come close to having an accident,which upsets you.You just escape maybe by a hair or

Words)词义包含两个方面：所指意义(Denotation)和隐含意义(Connotation)。所指意义是指词原来意思，如词典中所注明意思；隐含意义则是指词所暗含感情或想法。以country，nation，state和land为例。这四个词有着或多或少相同意义，都相当于汉字“国 家”，但 它 们 含 义 截 然 不 一 样。country指 疆 土、其 人 口 以 及 政 府。nation侧 重 指 主 权 国 家，也 指 国 民。state主 要 指 政 府 以 及 国 家 政 治 组 织。land比country意思愈加广泛，而且多见于文学作品中，并带有感情色彩。第28页 英语中同义词尤其丰富，因为英语在许多世英语中同义词尤其丰富，因为英语在许多世纪发展过程中，吸收了其它语言中大量词汇。但纪发展过程中，吸收了其它语言中大量词汇。但我们要切记，在英语中，极难找到在意思和使用我们要切记，在英语中，极难找到在意思和使用方法上完全相同两个词，它们在文体层次、强调方法上完全相同两个词，它们在文体层次、强调程度、感情色彩、语气和搭配上总是会有些许差程度、感情色彩、语气和搭配上总是会有些许差异。请看下面几组词语：异。请看下面几组词语：用词用词词义词义第29页(1)big和和large(2)small和little(3)modest和humble
