（1）主题句在开头或结尾：

(A)

①It was assumed generally that behavior was “caused” and that the causes of and the cures for crime would be discovered. Sick societies and sick individuals were the causes of crime. The traditional criminal justice system could be described as a band-aid and an ineffective “home remedy) “. The new, scientific approach, however, would cure the underlying causes of crime rather than concentrate on the symptom: criminal behavior.

②But does poverty cause crime?(Q1) It is certainly true that there is a very close link between low socioeconomic status and the sort of violent street crime that worries urban America so much. Furthermore, we must agree with Judge Bazelon that persons of low socioeconomic status probably

find it easier than others to true to violent street crime for money, excitement, or release.

also true that the majority of poor people are not violent criminals. Judge Bazelon is simply wrong

in his belief that poverty “causes” crime.(Q2)

③People sometimes think of crime as a combination of poverty and bad characteristics of a

criminal.Q1

but they may still have the desire for more wealth. In this aspect, crime seems no more related with poverty than with the behavioral features of the person involved in a case. Cyber-crimes and white-collar crimes can serve as good examples, the criminals are not short of money, they simply need more than they can gather and they will be happy to get more without having to work.

④Poverty is neither a sufficient nor a necessary cause of crime. 主题句(Q1)(Q2)Poverty

may make the choice to obey the law more difficult,the poor have choice whether to engage in crime, and the majority choose to obey the law. Is it true that no poverty, no crime? Improvement in the economic conditions of poor persons does not reduce the level of violent panics in periods of rising wealth. The “poverty cure” does not work . Attempting to get rid of poverty is

a worthy social goal,珍爱) for its own sake and not in the belief that it will cure crime.

( D ) 1. The most appropriate title for the essay would be ____ .（概括主旨、选定篇名题）易误选C

A. Economics and Crime

B. Wealth and Violence

C. Causes and Cures for Crime

D. Poverty and Crime

( C )2. Which of the following statements is a summary of the author’s ideas? ___ .（概括观点题）易误选A

A.Crime is a consequence of a low economic status.

B.Poverty should be cured before law and order can be kept.

C.Poverty does not necessarily cause crime.

D.Poor people are more likely to turn to violence.

分析：

Q1: 本文为议论文.选定篇名考查的是对文章主旨的把握.我们先看文章首尾或各段开头找主题句。

第一段（起始段）：落后的社会和个人会导致犯罪。消除犯罪的科学方法在于彻底消除引起犯罪的根源。

第二段：开头提出问题“Does Poverty cause c rime?”并指出：落后的经济状况与犯罪之间有密切联系。

第三段：人们认为犯罪是贫困和个人不良品行的结合。

第四段（结尾段）：贫困并非犯罪的充分或必要条件。穷人中大多数人还是守法的。消灭贫穷并不意味着消除犯罪。

从分析的第一段和结尾段以及各段开头可判断，文章论述的是贫穷和犯罪的关系。主题句为Poverty is neither a sufficient nor a necessary cause of crime.

（注：第一段中提到the causes of and the cures for crime would be discovered.学生很

容易误以为这就是文章的主题,选择(C).然而只要浏览全文便可知每一段都谈到poverty与crime 的关系,故答案选(D).）

Q2: 该题是一道概述作者观点的问题。这类问题一般不能从文中直接找到与答案完全相同的

句子，然而题目常用可从文中找到的原句作为选项之一（实为错误选项）迷惑学生。通过把握主旨，我们便可排除干扰选项。

文中第二段提到“It is certainly true that there is a very close link between low socioeconomic status and the sort of violent street crime that worries urban America so much.”

但从作者的措辞“It is certainly true that……”可判断这并非作者观点，而是他人的观点。

而且，第二段第五行YET以及第三段第二行BUT等转折词也提示读者作者持有不同观点，为最后一段的主题句“Poverty is neither a sufficient nor a necessary cause of crime.”做了铺垫。因此不可选A.只要耐心地看完该题全部选项，仔细推敲便可知C表示的意思就是文章的主题，即：作者的观点。故该题选“A”

注意: 本文的主题句在结尾。大部分文章的主题句在开头。但千万不可想当然认为主题

句都在开头,必须从头到尾浏览一遍,从全文内容把握主旨.

(2)主题句在中间：

(B)

Right now in schools across the country children are busy selling Pepsi-Cola in the name of education. They are part of Pepsi`s “Learn and earn Project”—a competition set up by Pepsi once a year that encourages students to sell the soft drink at parties, basketball games and other school functions.

Then, each spring, the students write up their Pepsi-selling success stories for a chance at national prizes: shares of stock in the Pepsi-Cola company.

According to materials the company sends the teachers, the project declares “help strengthen students` broad understandings of business, particularly its broad marketing and management aspects.”

Whether it fulfills this objective or not, it does succeed in selling Pepsi.Q1

The “Learn and Earn Project” is just one example of the hundreds of ways food companies encouraging the buying of their products in schools,Q1Q2主题句particularly in the fields of nutrition and home economics, companies send numerous “teaching aids”: highly professional films, shiny workbooks and pamphlets, all available to teachers at well below commercial rates or free.

For e xample, the Savennach Sugar Refining Corp. put out a book for students called “Sugar through the Ages” which includes the statements such as “Scientists have found that generous amounts of sugar are a valuable part of well-balanced diets for growing children.Q3 By far the largest supplier of nutrition-education materials to schools is the National Dairy Council, which provides all sorts of pamphlets addressing questions ranging from “How am I doing socially?” to “How am I doing physically?” These materials are full of things about dairy products, daily calcium requirement, etc. Drink mild, the message seems to be, and you too can be popular. But nutrition and home economics are not the only areas where companies have found a lucrative form of advertising.

( A ) 1. The main idea of the passage is that____.（概括主旨题）易误选B

A.various types of companies extended the selling of their products to school

B.pepsi`s “Learn and Earn Project” helps strengthen students` broad understanding of business

C.many big companies pro vide money for schools successfully by carrying out their “Earn

and Earn Project”

D.students learn much knowledge of nutrition and home economics through their practice of

business

(C)2. In quoting the statement from the book “Sugar Through the Ages”, the author’s

purpose is to __.（推断意图题）

A.to explain the educational function of the “teaching aids”

B.to praise the Savennach Sugar Refining Crop. from its scientific point of view

C.to expose the true motives (动机) of those companies in providing their “teaching aids”

D.to show how students and teachers can receive nutrition education more scientifically

( D ) 3. The author’s attitude towards Pep si’s practice is___ .（识辨语气题题）易误选A

A. disapproval

B. approval

C. optimistic

D. none of the above

分析:

Q1：本文段落多,内容较散乱,时而叙述事实，时而发表观点。要概括主旨，先从文章首尾入手找主题句。起始段：“百事”公司倡议“Learn and earn Project”活动，鼓励中学生在学校推销可乐。末尾段：某奶制品公司分发营养知识小册子。开头和结尾均没有明显表达中心思想或作者观点的句子,因此难以从文章首尾概括主旨.我们就要通过浏览全文来找出主题句或概括中心。

第三段概括了“Learn and earn Project”活动的宗旨：加强学生对市场及经济的了解。

有许多同学会以为这就是主题句，选“B”。.其实，浏览全文，可发现第四、五两段中作者提出了自己的看法，Whether it fulfills this objective or not, it does succeed in selling Pepsi. The “Learn and Earn Project” is just one example of the hundreds of ways food companies encouraging the buying of their products in schools.作者认为该活动真正目的在于销售可乐。因此可断定本文主题句为“Learn and Earn Project” is just one example of the hundreds of ways food companies encouraging the buying of their products in schools.

该题应选“A”.

Q2.. 推断题一般不能直接从文中找到答案，但绝不能凭主观猜测.例子的内容为: 制糖公司“成长中所需的糖分”一书中强调”学生成长过程中需大量的糖分”.作者揭示: 该公司表面上目的是让学生了解食糖方面的知识,实则向学生作广告,增加利润.这正是论证作者观点的一个例证.因此该题选“C”.

Q3. 识辨作者语气题首先也要把握文章主旨,其次找出反映作者态度的措辞.由于文章中心是Learn and Earn Project” is just one example of the hundreds of ways food companies encouraging the buying of their products in schools.首先排除B,C.本文中虽揭示了某些公司通过这种方法来增加销售量,但全文表明作者观点的语句中没有明显表示作者含有感情色彩的表示竭力反对的词语,故排除(A),选(D).

注意：

当无法从首尾找出主题句时，浏览全文，目标转向中间。在解答识辨语气题时，不可随意猜测，要找出依据，忠实于原文。

(3)中心贯穿于全文

(C)

On December 1,1955, Mrs. Rosa Parks boarded a bus in downtown Montgomery, Alabama, paid her fare and took a seat in the front of the Negro section at the back end. It felt good to sit down after a long day’s work. At the next stop, however, the driver told the Negroes to move back to make room for new white passengers.

All but one of the blacks gave up their places obediently. Rose Parks hesitated. The bus was now full: if she got up, she would have to stand all the way home. A white man waiting for her seat glared impatiently.

At that moment, something in Rosa Parks snapped. Maybe her soul had had enough of humiliation; maybe it was just that her feet tired. Anyway, the 42-year-old seamstress refused to give up her seat.

Black and white passengers alike stared at the troublemaker. The bus drier hailed a policeman. Mrs. Parks was arrested.

Montgomery’s 17,000 Negroes were enraged. Some wanted violence —“Burn the buses, tip them over.” Others kept their cool. With the help of a 27 Year-old preacher who had been inspired by the non-violent ways of Mahatma Gandhi, they organized a boycott of the bus line.

The boycott lasted 380 days, and cost the bus line millions of dollars. Finally, the U.S. Supreme Court affirmed that segregation on the buses was unconstitutional.Rosa Parks could now sit anywhere on a bus. Although most of us have forgotten her, the revolution she started changed America.

For the unknown preacher, however, there was no way back to obscurity. Martin Luther King, Jr., had a dream. And the world—at least in part because o Rosa Parks—was finally ready to honor that dream, and to listen.

…Acts of honor, all of them …Acts of sacrifice, integrity, love. And no one is laughing. Perhaps we have not lost our sacred Honor after all.

( C )1. The author’s chief intention in telling the story is .（概括主旨或推断意图题）易误选A

A. to expose racial discrimination in the 1950s

B. to applaud the non-violent boycott led by Martin Luther King, Jr.

C. to sing the praise of Rosa Parks` bravery and firmness

D.all of the above

( B )2．Which word best describes the character of Rosa?（概括人物特征）易误选A

A. stubborn

B. courageous

C. timid

D. arrogant

分析：

Q1: 由于本文为记叙文,无明显主题句,该文体的中心常贯穿于全文.对于这类文章，我们可以通过抓住动词来概括主要情节，从而归纳中心思想。本文线索: board----sit----be told to move----hesitate----refuse----be arrested---be enraged----boycott----desegregate---change America.Rosa上了公交车坐在黑人车厢，司机要求她将座位让给后来上车的白人。她犹豫了，但最终她拒绝让座，Rosa因此而被捕。黑人门被激愤了，组织了“抵制公交车”

事件。最终美国最高法院废除了公交车上实行的种族隔离制度。Rosa的这一行为改变了美国。

许多同学选(A),理由是文中叙述Rosa由于拒绝给白人让座而被捕是种族歧视现象,初看(A)没错.但这只是本文其中一个情节,是后文“抵制公交车”事件的导火线,并非中心思想.从以上分析的文章线索可确定本文主旨应为：Rosa坚强勇敢的行为迫使美国废除公交车种族隔离。作者的意图是赞扬Rosa的坚强无畏.应选(C)。

Q2: 通过对文章主旨的把握,首先排除(C)和(D).但同学有可能会选( A ),因为“stubborn”与第一题答案中“firm”相近.但“stubborn”是贬义词,意为”固执,倔强”.本文旨在赞扬Rosa 的坚

强勇敢,显然该词不恰当.(B)courageous (勇敢的=brave)才是最佳答案.

注意：

概括主旨要通篇考虑，不可以偏盖全，断章取义。处理概括人物特征题时必须从描述人物的动词和形容词仔细推敲,选择最贴近的词.

Ⅴ.主旨大意题（选择题）解题方法总结:

1.解答该题型最关键的是找出主题句，把握文章主旨。

＃通常情况下主题句在文中的位置:

＃因此概括主旨的方法是: 先看首尾或各段开头再看全文找主题句.若无明显主题句,就通过关键词句来概括.(如:议论文中寻找表达作者观点态度的词句,记叙文寻找概括情节和中心的动词或反映人物特点的形容词.)

2．文中出现两种或两种以上的不同观点时，务必牢记作者的观点才是体现全文中心的。

此时，要注意一些转折词，如：but,yet,however,although,in spite of,by contrast, on the contrary等。当文章中表示相反的观点时，往往用到这些词。答题时要弄清哪个是作者的观点，排除迷惑性信息，准确归纳主旨大意。

3．选定篇名或标题类题考查的也是学生对文章主旨的归纳概括能力，备选标题通常只是一个短语，甚至一个单词。在答题时必须仔细阅读文章，仔细推敲选项中直接引自语篇的措辞，既要排除过于具体或断章取义、以偏盖全的标题，又要排除范围太大、空洞、不着边际的标题，选出最佳答案。

4. 答推理题和识辨意图、语气题时，一般无法直接从文中找到答案，但绝不可凭空猜

测，也要找到依据。要通过文章主旨、字里行间或文中例子进行推断，通过含有感情色彩或描述情景的措辞来领会作者的态度或语气。

5. 必须看清题目，要求回答的是“全文主旨”还是“段落主旨”；推断的是“作者的观

点、意图”还是“别人的观点、意图”。

Ⅳ. 分析例题，掌握技巧

Passage A

A Be organized

B Get some sleep

C Write down the main points

D Remember the difficult bits

E Reward yourself

F Set yourself target

1.

It's always good to know what you're aiming for, so that you know if and when you get there. By having an aim for each week, or even each day, it will help you check your progress and show you if you need to change your plans.

2.

Rather than having to work through masses of notes every time you revised something, try noting down things you want to remember on a piece of paper. It doesn't seem as much to learn that way, but it makes sure you don't miss out anything important. Once you've learnt the main points, rewrite them on another piece of paper without looking at your notes.

3.

'If you don't know it by now, you'll never learn it for tomorrow.' Everybody says it, but it's probably true. Don't stay up all night studying. You'd better go to bed at a reasonable time,

so that you can wake up fresh and alert on exam day

4.

There's nothing worse than being disorganized. If you have a plan and stick to it, you won't end up cramming all your revision into the last few hours! Make a list of your exams and what you need to learn beforehand, and then draw up a timetable covering all the topics. You can then

work out what you need to do on a weekly basis and when you are going to do it.

5.

When you reach each of your targets, give yourself a treat—you deserve it! It could be a drink, a short break to watch your favorite TV program, a phone call to a friend —anything

you enjoy. Test yourself, from time to time, on a topic and if you do well, give yourself a special treat based on how well you have done.

第三段：不要熬夜复习，要保证充足睡眠。

第四段：拟定时间表，制定特定时间内需完成的任务。

第五段：达到一个阶段目标后，可以奖赏一下自己。

2．选定标题后，再把全文迅速看一遍，核对答案是否正确。

注：本文每段都具有明显主题句，与所提供的标题相对应。

小结：段落条理清，先找主题句

Passage B

A Burst of anger

B No harm guaranteed

C The cause of protesting

D Measures against GM food

E Knowing about GM food

F Fast development of GM food

1.

The battle heats up between the U.S. and Europe over genetically modified food(转基因食品). The staff at McDonald's could not have expected an especially warm reception in France,

but the manure(粪便) in the parking lots still must have taken them by surprise. For the past

three weeks it's been hard to visit a McDonald's anywhere in France without running the risk of meeting with mountains of fresh manure as well as, lots of fruit and vegetables dumped in front

of the restaurants by protesting(抗议) farmers.

2. The cause of protesting

There's a lot about McDonald's that angers the farmers. Protesters are finding even more

to dislike about the uniquely American food, especially the very genes(基因) that make the McDonald's beef or bun or potato what it is.

3.

Around the world people are taking a closer look at the genetic make-up of what they're

eating and growing uneasy with what they see. Over the past decade, genetically modified

(GM) food has become an increasingly common phenomenon as scientists have rewoven the genes of countless fruits and vegetables, turning everyday crops into crops able to resist severe cold, insects, and even produce their own pesticides.

4.

For biotech companies such as Monsanto based in the U.S., and Novartis AG, based in Switzerland, the rise of GM technology has meant boom times. Sales of GM seeds rose in

value from 875 million in 1995 to 81.5 billion last year, and the crops they produce are

turning up not only on produce shelves but also in processed foods from cookies to potato

chips to baby food.

5.

But many people question whether it's a good idea for human beings to eat those foods. Up

to now, there's nothing to suggest that GM foods have ever done anyone any harm. Nevetheless,

the European Union has blocked the import of some GM products, and since 1997 has required

that foods containing engineered DNA be labeled as such. At the same time, the US Congress

also addressed a labeling bill of its own later this year, and some private groups are threatening court action to force the issue. Even without legal action, public opinion is turning a more doubtful eye on GM technology.

分析：

1．从标题看，我们可了解大意。本文大致内容为人们对GM食品的了解，GM食品的发展以及人们对其的抗议。各段落中无明显主题句，我们可通过找关键词来概括段落主旨。第一段：法国农民在麦当劳的停车场及门口堆积粪便、蔬菜等以表示对GM 食品的抗议。可概括为：农民对GM食品暴发的愤怒，关键词句为“…mountains of fresh manure as well as, lots of fruit and vegetables dumped in front of the restaurants by protesting(抗议) farmers.”因此第一段标题可确定为A:Burst of anger.

第二段：麦当劳有众多令农民愤怒的原因，尤其是对食品进行转基因处理。关键词句为：There's

a lot about McDonald's that angers the farmers.。可确定该段标题为C: The cause of

protesting.

第三段：由于人们了解到科学家将食品中的基因进行重新处理，发明出转基因食品，使其能

增强抵抗力，人们对此感到担忧。因此可概括为对转基因食品的了解。该段标题为E: Knowing about GM food.关键词句为：“…taking a closer look at the genetic make-up of…”。

第四段：GM food经历繁荣时期，GM食品种子的销量也急剧上升，而且涉及范围也逐步扩大。关键词为：“boom times , rose”.因此不难判断该段标题为F: Fast development of GM food.

第五段: 开头：人们提出疑问GM food 对人体是否安全。紧接着是“There is nothing to suggest that GM foods have ever done anyone any harm.”。学生可能认为这便是作者的观点，本段的中心，而误选 B No harm guaranteed。但如果读完整段，可发现转折词“Nevertheless”提示语气的转折，暗示人们并不因为没有迹象表明GM food对人体有危害而不对它产生怀疑。其中提到四种限制GM food 的措施。因此标题为D. measures against GM food。

2．选定标题后，再把全文迅速看一遍，核对答案是否正确。

小结：注意转折词语，准确归纳中心。

Passage C

A Scientific facts

B Analysis and inference

C Two kinds of causes

D Supporting evidences

E Further studies

F A research conclusion

1.

Acid rain has increasingly thinned the shells of eggs laid by British birds over past 150 years, a new study suggests. Biologists fear that the trend could cause eggs less likely to hatch.

2.

In a paper, Rhys Green, a scientist, reveals a steady decline in eggshell thickness totally be- tween 2 to 11 per cent, depending on the species in Britain. Because the collection sites are well documented, Green is confident that the changes he has recorded are real, rather than false facts caused by eggs being taken from different geographical areas at different times.

3.

But what could be to blame? Pesticides such as DDT are known to cause thinner shells in birds of prey. However, these chemicals only became widely used in British agriculture in 1947, well after the thinning of the birds eggshells began. Green thinks that acid rain, caused by sulfur emissions from burning of fossil fuels, is the most likely cause. This would reduce both the calcium content of leaf waste consumed by worms and the abundance of snails, which together make up a large part of the birds diets.

4.

Eggs laid by great tits--a kind of big bird--living in areas with heavily acidified soils have

also been found to have thinner shells than normal, Green notes. One study in Germany, published in a journal, found that eggshells from birds living in areas where soils are highly acidic were 2.7 percent thinner than those from lime-rich areas.

5.

More studies are needed to identify exactly how historical increases in soil acidity relate to trends in eggshell thickness, says Green. And it is still unclear whether the changes are affecting

the birds' survival. 'Whether these processes actually affect the conservation of the birds is not

yet certain,' says Green.

分析：

1．从标题所提供信息来看，我们只能了解本文是对某现象或事物的研究，关于其事实、分析、推断、起因、依据、研究结果等，标题未提供有关文章内容的具体信息。对于这种情况，同学可先浏览全文，大致了解全文大意和段落关系，再分段阅读，选出合适标题。

全文大意：生物学家通过研究、收集各类事实和依据，推断酸雨导致鸟类蛋壳变薄。

第一段：从“a new study suggests…”可知，这是科学家通过研究证明的一个结果，因此应选F:A research conclusion.

第二段：科学家们通过收集同一地区的蛋壳，揭示“蛋壳变薄”这一现象。因此这属于一个科学事实，标题选A:Scientific facts.

第三段：从该段第一句可知，该段分析上述现象“蛋壳变薄”的起因。文中提到两个起因：使用杀虫剂以及酸雨。因此很容易误选C.事实上，本题中，C选项是一个迷惑性很强的干扰项，大家仔细阅读，会发现科学家认为英国农业使用DDT之前，该地区鸟类蛋壳变薄现象早已产生。因此Green通过分析，推断酸雨才是最可能的原因。因此该题选B:Analysis and inference

第四段：作者例举另一生活在土质酸化地区的鸟类tits（山雀）的蛋壳变薄的例子。德国一研究发现土质酸化地区的鸟类蛋壳比土质肥沃地区的薄2.7%。有同学从study 一词可能误选E: Further studies.我们可先读一下第五段：大意为：要断定土壤酸化程度与蛋壳厚度之间的关系以及酸雨是否真正影响鸟类生存与保护还需进一步的研究。由此可判断E “Further studies”作为第五段标题更为恰当,而第四段的事例正是证明第三段中的推断“Acid rain is the most likely cause of thinner shells”的“supporting evidences (依据) ”.

故第四段标题为D“Supporting evidences”.

2．. 选定标题后，再把全文迅速看一遍，核对答案是否正确。

注：本文内容初看较为散乱，而且生词较多，但只要弄清文章结构和段落之间的关系便

可帮助我们确定段落主旨。另外，在遇到难以选定段落标题的情况时，可先跳过一

段，先处理内容简单，容易概括主旨的段落，缩小标题选择范围，便于答题。

小结：把握文脉走势，理清段落关系。准确概括主旨，排除干扰选项。

Ⅴ. 总结新题型答题技巧：

1．该题型的关键是理解标题含义，找出段落主题句或归纳段落主旨，因此不必逐字阅读，遇到生词，跳过去继续阅读。

2．不能只从文章字面找到与某个标题一致的字眼或短语就将其配对，要从字里行间，文脉走势判断段落大意。

3．如果找不到主题句、中心词，又难以从关键词以及字里行间概括段落主旨，

也可通过把握全文主旨、理清段落关系来判断段落大意。

常见的段落关系有：时间，对照，比较，因果，分类等。

4．如果对某一段的标题难以作出判断，可先跳过去，先确定较简单的段落的标题，缩小标题选择范围。

5. 注意一些转折词（尤其在议论文中）：in spite of ,however, although, but,

nevertheless, in contrast等。这些词经常为正确把握段落中心提供了信息。6．本大题的难点在于：多余的标题有很强的误导性，与其中一个正确标题的意思相近或与某段的大意相近，迷惑学生，使其难以作出判断。此时，不可疏忽大意，不可随意选一个，应反复推敲标题的含义和措辞，选择最符合该段落中心的标题。
