1、第三讲理清文架构核心抓段落构成知主题句一、段落的构成英语文章段落结构一般由三部分构成：主题句(topic sentence)，扩展句(development sentence)和结论句(closing sentence/concluding sentence)。主题句点出段落的主题，扩展句解释说明或论证主题，结论句总结、归纳或概括主题。1主题句主题句，就是段落的核心句、纲领句、主旨句、中心思想句，言简意赅，主旨鲜明。它是段落的灵魂，表达段落的主题，在英语文章段落中居于主导地位，其他句子都要围绕它而展开。英语文章一般喜欢开宗明义，所以主题句一般位于文章段首，但有时也在段中或段尾。2扩展句扩展句就

2、是为主题句起解释说明或论证作用的句子。扩展句一般长度适中，有一定的条理和逻辑。扩展句的展开方法多种多样，通常采用的方法有举例说明、描述、定义、比较对照、因果分析、分类等。3结论句结论句就是总结句，会重述或总结段落的中心论点，与主题句相呼应。需要指出的是，英文段落中结论句并不多见，我们通常看到英语的文章段落结构60%一70%都是由“主题句扩展句”构成。典例Why fiction is superior to textbooks lies in their imagination(主题句：以自问自答的方式提出段落主题)Authors of the fictions always create at

3、tractive characters so as to give his opinion about nature and the society as well as life(扩展句1)It not only provides knowledge，but also teaches us what is the right attitude toward life (扩展句2)For instance，we can learn from Gone with the Wind how to be a strongwilled person；from Jack London，how to lo

4、ve life(扩展句3：基于上述观点，进一步举例说明)We can be stimulated to overcome all obstacles to realize our ambitions(扩展句4)So，fictions enable people to form their positive view of life，the spirit of optimism and invincible courage，and provide us with an opportunity to learn and to practice，while textbooks barely can

5、(结论句：归纳总结段落主题)二、段落主题句的位置 在进行阅读理解时，我们要善于找出段落的主题句，这样才能抓住文章段落的中心思想(controlling idea)。主题句在段落中的位置并不是一成不变的，而是根据作者组织段落的方法或强调的重点而定。大多数情况下，主题句在段首，有时会在段中或段尾。无论主题句的位置在哪儿，主题句都包含一个逻辑性强且层次分明的中心思想。1主题句在段首这是主题句在段落结构中最常见的位置，这种安排开门见山，点出主题，读者可以迅速了解文章主旨。典例Although smoking has been a popular habit for centuries，it has a

6、lways had its enemies(主题句)Some American Indians advised young braves not to smoke too much because tobacco would cut their wind(削弱力量)in a hunt or a battle.King James of England called smoking “a branch of the sin of drunkenness，which is the root of all sins”Ben Johnson，the playwright，said smoking wa

7、s“good for nothing but to choke a man and fill him full of smoke and embers”Popular slang called cigarettes“coffin nails”long before the medical evidence on the hard from smoking was complete.Now every package of cigarettes and every advertisement for cigarettes must carry a warning from the Surgeon

8、 General(卫生局局长)that smoking is hazardous to health.2主题句在段中 主题句出现在段中时，位于主题句之前的部分通常起到承上启下的作用，而主题句后面的部分则围绕主题句展开讨论或阐述。此类主题句并不一定在段落正中位置，可能靠近段首，也可能与段中的结论句相邻。典例My parents have gone out for the evening.Just as I settle down to read or watch TV，my little brother demands that I play with him.If I get a teleph

9、one call，he screams in the background or knocks something over.I always have to hang up to find out whats wrong with him.Babysitting my brother is no fun(主题句)He refuses to let me eat a snack in peace.Usually he wants half of whatever I have to eat.Then when he finally grows tired，it takes about an h

10、our for him to fall asleep.3主题句在段尾主题句位于段落的结尾，是对段落主旨进行概括和总结。主题句位于段尾的好处是会给读者留下深刻印象。典例Some people dream of starring roles，their names in lights，and their pictures on the cover of magazines.Some would even go out of their way to get their name.However，I am not one of these people.A famous person gives u

11、p private life，feels pressured all the time，and is never completely safe.So，let someone else have that cover story，take the starring roles and have a big name.Id rather lead an ordinary，but calm life rather than a stressfilled public one(主题句)理段落展开析句间关系在段落中，般会有两个甚至多个扩展句对中心思想进行论证、解释，这也就是段落的展开。段落的展开模式多

12、种多样。这里我们着重介绍9种段落展开模式。列举型列举法是比较常见的段落展开法。按此类方法展开的段落中，作者会先点明主题，提出论点，然后列举一系列的论据进行陈述或解释。列举的内容可以是一系列的事物、事件、理由或者一个问题的不同方面。列举的顺序可以是时间的先后、地理位置的远近或者内容的相对重要性等。典例The sentences in most well written paragraphs may be analyzed into three general functions.First，there are paragraph introducers，which are sentences t

13、hat establish the topic focus of the paragraph as a whole(列举1)Second，there are paragraph developers，which present examples or details of various kinds that support the ideas set forth by the paragraph introducers(列举2)Third，there are paragraph terminators，which logically conclude the ideas discussed

14、in the paragraph in a psychologically satisfying manner(列举3)Not all pieces of writing will conform to this analysis；however，most successful paragraphs usually contain the same combination of these three sentence types.举例型举例法是用具体的事例来说明段落主题，也是一种常见的段落展开方法。此类段落中，作者往往开门见山，点出主题，然后列举具体事例(一个主要例子或多个相关例子)进行说明

15、。所举事例一般较具体，可以是日常事件、现象、个人经历、名人轶事等等。典例The ability to write wellorganized，concise(精确的)paragraphs is essential(必要的)to a students success in almost all university courses.In preparing scientific reports of laboratory experiments，a student must present his or her findings in logical order and clear langua

16、ge in order to receive a favorable evaluation(评价)of his or her work(举例1)In writing successful answers to essay questions on history or anthropology(人类学)examinations，a student must arrange the relevant facts and opinions according to some accepted pattern of paragraph structure(举例2)And certainly in w

17、riting a book report for English，or a critique(评论)for political studies，or a term paper for sociology，a student must pay attention to the style and organization as well as the content(举例3)Clearly，skill in expository writing(说明文)is crucial to successful achievements in most university subjects.描述型段落也

18、可以用描述的方法来展开。常见的描述法有三种：时间顺序、空间顺序和过程顺序。这三种模式使段落的层次体现了一定的次序关系。用这种模式展开段落，作者能够清楚连贯地交代事物的本末，读者可以容易地理解段落的主旨。1时间顺序这种方法主要是以事情发生的时间顺序或先后次序来展开段落。常出现在描述历史、时事、人物或事件的发展过程的文章中。描述顺序有“顺序”、“倒序”和“插序”。典例Bill Gates stepped down as chief executive officer of Microsoft in January,2000.He remained as chairman and created t

19、he position of chief software architect.In June,2006，Gates announced that he would be transitioning from fulltime work at Microsoft to parttime work，and fulltime work at the Bill & Melinda Gates Foundation.He gradually transferred his duties to Ray Ozzie，chief software architect，and Craig Mindie，chi

20、ef research and strategy officer.Gates last fulltime day at Microsoft was June 27,2008.He remains at Microsoft as nonexecutive chairman.(顺序)2空间顺序按照空间顺序展开的段落主要见于描述场所或空间、人或物的空间位置及其相互关系的文章中。典例It is a beautiful and quiet night.The moon is like a disc hanging in the dark sky，which casts its light on ever

21、ything.Around the lake are some trees，their slender leaves blowing in the gentle wind.There must be some frogs in the middle of the lake，whose endless singing can be heard clearly.What an attractive night！(由上及下，从远到近)3过程顺序过程顺序法主要是描述做一件事情应该遵循的程序或步骤。这种段落展开的方法多见于培训手册、科技文章和操作说明书中。典例The ancient pyramids o

22、f Egypt continue to fascinate and amaze people nearly five thousand years after the Egyptians built them.Constructing each massive(巨大的)pyramid was difficult and dangerous labor，requiring thousands of workers and years of toil.First，heavy limestone (石灰岩)blocks were taken from quarries(采石场)located nea

23、r the Nile River(步骤1)Then the blocks were transported by wooden boats to a point as close as possible to the intended building site of the pyramid(步骤2)Next，the blocks were unloaded and slowly hauled to the actual site by means of sledges(重型运输雪橇)positioned atop wooded rollers(滚筒)(步骤3)As construction

24、proceeded，the Egyptians moved each successive(依次的)block into position using ramps(滑轨，斜坡)made of bricks of dried mud(步骤4)Incredibly，the huge pyramids were completed without the aid of bulldozers(推土机)，cranes(起重机)trucks，or other modernday construction equipment.Even so，the tallest pyramid rose higher t

25、han a fortystorey building！Equally remarkable，numerous pyramids still stand today，almost fifty centuries since their construction.比较对比型比较对比法是将两个可比的项目进行比较以找出其相同点或进行对比以找出其不同点。比较或对比的方法有两种；一种方法叫整体法，即先讨论A的特点，再讨论B的特点，即A1，A2，A3；B1，B2，B3。另一种方法叫逐项法，即将A的特征与B的特征交替比较或对比，即A1，B1；A2，B2；A3，B3。1整体法典例Laws and ethics(

26、伦理)are not quite the same.In general，laws are societys attempt to formalizereduce to written rulesthe general publics ideas about what is considered right and wrong conduct in various spheres of life.However，it is rarely possible for written laws to capture all of the subtle shadings that people inc

27、lude in the codes of ethics they use to govern their lives.Ethical concepts(伦理观)，or moral principles(道德准则)like the people who believe in themare more complex than written rules of law.Ethical concepts are ideas about right or moral conduct，and they cannot always be expressed in the formal language o

28、f law or in rules.(A1，A2；B1，B2)2逐项法典例In college and university courses，the objective test and the essay examinations are two contrasting methods of evaluation commonly used to measure a students grasp of subject matter.The objective test usually consists of a large number of unrelated questions that

29、 require the student to demonstrate mastery of details.It often leads to rote memorization(死记硬背)of isolated facts during the pretest study.Since the questions on the objective test are presented in truefalse or multiple test form，the student may be encouraged to guess answers for which he has no acc

30、urate(准确的)knowledge.The essay examination，on the other hand，usually consists of a few broadly stated questions that require the student to give proof of his ability to handle general concepts.This type of examination also relies on factual information，but there is far greater necessity for the stude

31、nt to demonstrate analytical and compositional skills.Mere guessing at answers is reduced to a minimum.Although the objective test and the essay examination have similar goalsthe assessment of a students academic achievementthe techniques (and very often the results) of the two types of examination

32、differ significantly.(A1，B1；A2，B2；A3，B3)因果分析型因果分析法是通过分析事物发展的原因及其结果来说明段落的主题。无论是说明原因还是阐释结果，都有行文逻辑可寻。此种方法通常有两种模式：原因在前，结果在后；结果在前，原因在后。1原因在前，结果在后典例According to statistics，China has one of the highest traffic fatalities in the world，and alcoholrelated traffic fatalities had been increasing and had very ba

33、d influence on the society(原因)Because of this，stricter punishment had been imposed on drunk drivers，and stricter laws had been passed on drunk driving(结果1)As a result of this，drunk driving and alcoholrelated traffic fatalities have been on the decline(结果2)2结果在前，原因在后典例During the past five years，the n

34、umber of Americans killed annually in car accidents has climbed to more than 55,000(结果)This needless slaughter(屠杀)on streets and highways can be attributed to(归因于)three general causes.Mechanical failures，especially those related to faulty brakes and bald tires，account for a significant number of fat

35、al(致命的)accidents(原因1)Environmental conditions such as blind corners，narrow streets，heavy fog，intermittent(间歇的)rain or snow resulting in slippery roads also contribute to the accident statistics(原因2)But without doubt the most frequently reported factors in car accidents are errors of human judgmentsa

36、ll the way from such follies as excessive speed and drunk driving to such momentary lapses(失误)as failure to signal a turn or a change from one lane to another(原因3)The man behind the wheel is often his own worst enemy.分门别类型分门别类，顾名思义，就是按照一定的标准，将某一复杂的事物进行分组归类。一种复杂的事物往往可以根据其性质、形态、成因、功能等属性分成若干类，然后逐一说明。这种

37、方法既可以展示事物的共性，又可以展示事物的特性，多见于科技类的英语阅读文章中。典例Individual paragraphsthe building blocks of essays，articles，chapters，and other longer papersmay be classified in a variety of ways.At the essay level，paragraphs may be sorted into functional groups such as introductory，developmental，transitional，concluding，an

38、d the like(分类1)Depending on the purpose or intent of the writer，particular paragraphs may be thought of as aiming to persuade，inform，argue，or excite(分类2)Paragraphs may also be classified according to such techniques of development as comparison，contrast，and definition(分类3)Another developmental devic

39、e might also be the classification paragraph，which organizes items or ideas to be discussed into relatively homogeneous(同种类的)groups(分类4)Such classifications make it possible to talk about a large number of paragraphs by grouping them into a small number of classes.定义型定义法是用简单而准确的语言描写某一事物的属性，或解释说明一个专业

40、术语或者某一概念，特别是抽象概念。这种方法常见于说明文、应用文或议论文中。一般来说，用定义法展开的段落包含两部分：首先是定义句，概述被定义物的性质；其次，展开叙述有关方面的内容，如来源、性质、结构、特征、原理、用途等。典例A rain forest，as the term suggests，is a kind of wooded area，subject to usually heavy and frequent rain (定义句)Found only in the tropical and subtropical(亚热带的)regions of the Caribbean，Brazil，A

41、frica，and Asia，rain forests contain a great variety of trees including bamboo，palm，cedar，ebony，calabash，and whitewood(来源)Many of these trees grow to a height of more than a hundred feet，with dense canopies(树冠)or crowns forming three storeys.Although ground plants are rare，climbers of all kinds aboun

42、d(充满)，and often exotic flowers appear in thick leaves.This luxuriant(茂盛的)growth results from an annual rainfall in excess of ninety inches，with no dry season(特征)概括型概括法与举例法类似，这两者都是用事例来说明段落主题。概括法强调结论是基于事例所说明的事实和观点而得出的。而且这一结论易于被读者接受。典例The surface of the earth is chiefly watersomething that we，as dwelle

43、rs(居住者) on the land，are apt to ignore or completely forget.As stated earlier，the Pacific Ocean alone covers nearly one third of the globe.The combined areas of all water bodies，including oceans，seas and lakes add up to nearly two and onehalf times that of all the land of the earth.In other words，abo

44、ut 71 percent of the earths surface is water.In addition to the large expanses(陆地、海洋等广阔区域)just mentioned，there are small ponds，waters that run as streams on top of the land，and other waters that lie or move within the upper portion(部分)of the earths crust(地壳)And there is water in vapor(水蒸气)and conden

45、sed forms in the atmosphere.Thus，water is an important and practically all pervasive(遍布的)element in mans habitat (概括句)综合型前面我们介绍了8种段落展开模式。然而在多数情况下，段落的展开方式多样而富于变化，常常是几种模式互相结合，互为补充，这种段落展开方式我们称之为“综合型”。典例1Increasing your vocabulary can help you in a number of ways(分门别类法)You discover that knowing synonyms

46、，for example，will decrease the amount of repetition in your compositions and make them more enjoyable to read(举例法)And if a teacher enjoys reading your paper，he may give you a better grade.Also，an increasing vocabulary will make your own reading more enjoyable.You will find it much easier to follow t

47、he ideas in your history text book and the newspaper when you do not have to continually run to the dictionary to look up an unknown word.You will become more eager to read and not as discouraged when you do come across an unknown word.As a result，you will read faster and more intelligently，become m
