Reading ComprehensionPassage 1"Culture consists of all shared products of human society¡± (Robertson ,1981). This means not only such material things as cities, organizations and schools, but also non-material things such as ideas, customs, family patterns, and languages. Putting it simply, culture refers to the entire way of life of a society, "the ways of a people¡±.Language is a part of culture and plays a very important role in it. Some social scientists consider it the keystone of culture. Without language, the maintaining of culture would not be possible. On the other hand, language is influenced and shaped by culture, and it reflects culture. In the broadest sense, language is the symbolic representation of a people, and it comprises (°üº¬)their historical and cultural backgrounds, as well as their approach to life and their ways of living and thinking.We should not go further into the relationship between language and culture. What needs to be stressed here is that the two interact (Ï´»¥Ó°Ïì), and that understanding of one requires understanding of the other.Social scientists tell us that cultures differ from one another, that each culture is unique. As cultures are diverse, languages are diverse. It is only natural that with differences in cultures and differences in languages, difficulties often arise in communicating between cultures and across cultures. Understanding is not always easy.Learning a foreign language well means more than merely mastering the pronunciation, grammar, words and idioms. It also means learning to see the world as native speakers of thatlanguage see it, learning the ways in which their language reflects the ideas, customs, and behaviors of their society, learning to understand their "language of the mind¡±. Learning a language, in fact, is inseparable (²»¿É²Ö¸îµÄ)from learning its culture.1. According to the first paragraph, the term "culture¡± refers to _________.A. things like cities, organizations and schoolsB. ideas, customs, family patterns and languagesC. all things manufactured by human raceD. the total that constitutes a society2. The second paragraph tells us about _________.A. the role of language in cultureB. the relationship between language and cultureC. the influence of culture on languageD. the representation of culture3. Which of the following statements is NOT true according to some social scientists?A. Language reflects cultureB. Language shapes cultureC. Language represents cultureD. Language maintains culture4. The passage implies that there will be no difficulty in communication if people from differentcountries can _________.A. speak each other's languagesB. master each other's languages and culturesC. tell the differences between languages and culturesD. communicate in the same languages5. This passage is probably taken from a book _________.A. on culturesB. on language learningC. on learning a language through cultureD. on communication in different countries Passage 2After 10 seasons wearing the No 8 on his back, Kobe Bryant will become No 24 next season. The reason for the surprising decision by the Los Angeles Lakers super guard last week has become a hot topic for debate.Bryant wore No 24 when he was in early high school, but he changed to No 33 in his senior year. He switched to No 8 when he was selected by the Lakers in 1996,and has not been changed since.Bryant has refused to explain the decision until the end of the play-offs (¼¾ºóÈü). So guessing Bryant's motive has become a popular game among NBA fans and newspaper columnists (³¨À¸³÷¼Ò).There are all kinds of speculations. Many say that Bryant wants to leave the past behind and have a fresh start. He has often been criticized for playing to benefit himself and not the team as a whole. Others say that he may be trying to compare himself to Michael Jordan. Jordan was famous for his No 23 jersey (Ô˶¯ÉÀ). Some, such as NBC Sport columnist Michael Ventre, argue that it is "all about money¡±. Bryant will make more money by selling new jerseys to his fans.Some speculations are more about fun. For example, there is an opinion that Kobe is actually just a diehard (²Ç³£Ö´ÖøµÄ) fan of the popular TV drama "24¡±.All this talk has turned the number change into a major issue. It seems that there is a lot of fuss (´ó¾ªÐ¡¹Ö) over something that should be pretty simple.Jersey numbers have their own special significance in American sports, especially basketball. Players choose their number when they join a team and they usually stick with that number for the rest of their career. When a great player retires, his team will honor him by retiring his number.To some extent, the jersey is the player, and the player is the jersey. Thus, when you see the famous No 23 for the Chicago Bulls, you immediately think about Michael Jordan. A No 32 Miami Heats jersey recalls the image of Shaquille O'Neal, and the Houston Rockets' No 11 belongs only to Yao Ming.Lots of stories are behind players' jersey number selections. Jordan said that he chose No 23 because it was roughly half of 45. Jordan's elder brother wore the No 45 in college. Yao Ming once revealed that the No 11 stands for two people in love¨D meaning him and his girlfriend Ye Li.1. Which team has Bryant played for?A. The Los Angeles Lakers.B. The Houston Rockets.C. The Chicago Bulls.D. The Miami Heats.2. How long has Bryant been wearing No 8?A. Since he started to play basketball.B. For ten seasons.C. Since he entered high school.D. Since he left the Lakers.3. Which of the following is NOT a speculation about Bryant's motive to change his number,according to this passage?A. He wants to leave his past behind and have a fresh start.B. He wants to compare himself to Jordan.C. He wants to earn more money.D. He wants to show that he is a man of great importance.4. Why did Jordan choose No 23?A. Because that number would make him famous.B. Because that number would make his fans miss him.C. Because that number was related to the number his brother once wore.D. Because that number was easy to remember.5. What does the number Yao Ming chose stand for?A. Two long legs.B. Two strong arms.C. Two people in love.D. Two big countries.Passage 3Anna Douglas was 72 years old when she started writing her newspaper column (³¨À¸). After she retired, she found a volunteer job with an agency. The agency that she chose to work for was a business that helped other businesses find jobs for old people. Every day she talked with other retired people like herself. By talking, she recognized two things. Old people had abilities that were not being used. Old people also had problems--mostly problems with communication.Mrs. Douglas found a new purpose for herself. Through the year, from time to time she had written stories about people for national magazines. Now there was a new subject: old people like herself. She began to write a newspaper column called: "Sixty Plus,¡± which focuses on gettingold. She writes about the problems of old people, especially their problems which being misunderstood.Anna Douglas used her thinking ability to see the truth behind a problem. She understands the reasons why problems begin. She understands old people and young people, too. For example, one of her readers said that his grandchildren left the house as soon as he comes to visit. Mrs. Douglas suggested some ways for him to increase understanding with his grandchildren. She told him to listen to young people's music and to watch the most popular television shows."It's important to know something about your grandchildren's world,¡±says Mrs. Douglas. "That means questioning and listening ¨D and listening is not what old people do best.¡±She continues, "Say good things to them and about them. Never criticize (ÅúÆÀ) your grandchildren or any other youngsters, teenagers, or young adults. Never tell them that they are wrong. Don't give them your opinion. They have been taught that they should have respect for old people. The old should have respect for the young as well.¡±1. Anna Douglas understands the problems of old people because _________.A. she herself is oldB. she likes their musicC. she has grandchildrenD. she watches their television programs2. Anna Douglas' newspaper column_________.A. contains mostly funny storiesB. has some ideas for youngstersC. is about how to find jobs for old peopleD. discusses the problems of the aged3. What advice did Mrs. Douglas NOT give to the reader whose grandchildren didn't want tosee him?A. Listen to pop musicB. Watch more popular TV showsC. Tell more interesting storiesD. Try to understand his grandchildren4. According to Mrs. Douglas, old people need to learn how to _________.A. workB. criticizeC. listenD. complain5. According to the last paragraph, the main point of Mrs. Douglas' advice is that old people_________.A. have a lot to learn from the youngB. should understand and respect the youngC. had better improve their hearing not to misunderstand the youngD. should show respect for the young even when criticizing themPassage 4Like fingerprints, no two faces are exactly the same. Did you ever wonder how it is possible for us to recognize people? Even a skilled writer probably could not describe all the characters that make one face different from another. Yet a very young child ¨D even an animal, such as a bird ¨D can learn to recognize faces. We all take this ability for granted.We also tell two people apart by how they behave. A person's personality means the ways in which he acts, speaks, thinks, and feels that make him different from others. Like the human race, human personality is very complex. But describing a person's personality in words is somewhat easier than describing his face. If you were asked to describe what a "nice face¡± looks like, you would have a difficult time doing so. But if you were asked to describe a "nice person¡±, you might begin to think about someone who is kind, thoughtful, friendly, warm, and so on.There are many words that can be used to describe how a person thinks, feels, and acts.Gordon Allport, a U.S. scientist who studies the human mind, found nearly 18,000 English words characterizing differences in human behavior. And many of us use these words to describe different types of people ¨D bookworms (Êé´ô³Ó)£¬fools, workaholics (¹¤³÷¿ñ).1. According to the passage, a very young child can _________.A. learn to recognize facesB. describe how a person thinksC. learn to recognize fingerprintsD. describe what a "nice person¡± is like2. According to the passage, we can tell two people apart by _________.A. their behaviorB. their namesC. their handsD. their clothes3. Describing a "nice face¡± _________.A. is quite easyB. is a difficult taskC. is not as difficult as describing a "nice person¡±D. may remind you of someone who was kind, thoughtful and friendly4. It can be concluded from the passage that ______.A. a "nice person¡± is very complexB. it's hard to describe a "nice person¡±C. a "nice person¡± is considerate and kindD. when we tell one person from another, we often refer to their faces5. Which of the following statements is NOT true about Gordon Allport?A. He describes himself as a bookworm.B. He does research on the human mind.C. He found about 18,000 English words to describe human behavior.D. The words he found are being used by many people to describe a person.II. Answer teh following questions briefly.1.

Reading ComprehensionPassage 1People all over the world today are beginning to hear and learn more and more about the problem of pollution. Pollution is caused either by man's release of completely new and often artificial (ÈËÔì)substances into the environment, or by releasing greatly increased amounts of a natural substance (ÎïÖÊ), such as oil from oil tankers into the sea.Whatever its underlying reasons, there is no doubt that much of the pollution caused could be controlled if only companies, individuals and governments would make more efforts. In the home there is an obvious need to control litter and waste. Food comes wrapped up there or four times in packages that all have to be disposed of; drinks are increasingly sold in bottles or tins whichcannot be reused. This not only causes a litter problem, but also is a great waste of resources, in terms of glass, metal and paper. Advertising has helped this process by persuading many of us not only to buy thing we neither want nor need, but also to throw away much of what we do buy. Pollution and waste combine to be a problem everyone can help to solve by cutting out unnecessary buying, excess use and careless disposal (´¦Àí) of the products we use in our daily lives.1. The main cause of pollution is______.A. the release of artificial or natural substances into the environmentB. the production of new industrial goodsC. increased amounts of a natural substanceD. our ever-increasing population2. Much of the pollution could be controlled if only______.A. people would pay more attention to the problemB. governments would take effective measuresC. all sides concerned would make more effortsD. farmers would use less artificial fertilizers3. Food packages, bottles and tins for drinks can cause______.A. air and water pollutionB.both a litter problem and a waste of resourcesC. to pay for the serviceD. to produce the receipt4. Which of the following can not help solving the problem of pollution?A. Cutting out unnecessary buyingB. Eating lessC. Reduce excess useD. Carefully dispose our daily products.5. What does the underlined word "litter¡± mean in paragraph 2 ?A. not manyB. serious problemC. bits of waste thingsD. industrial pollution Passage 2The young people who talk of the village as being "dead¡± are talking nothing but nonsense, as in their hearts they must surely know.No, the village is not dead. There is more life in it now than there ever was. But it seems that "Village life¡± is dead. Gone for ever. It began to decline (Ë¥Âä) about a hundred years ago, when many girls left home to go into service in town many miles away, and men also left home in increasing number in search of a work, and home was where work was. There are still a number of people alive today who can remember. What "village life¡± meant the early years of the present century? It meant knowing and being known by everybody else in the village. It meant finding your entertainment in the village of within walking distance of it. It meant housewives tied to the home all day and every day. It meant going to bed early to save lamp ¨Doil and coal.Then came the First World War and the Second World War. After each war, new ideas, new attitudes, new trades and occupations were revealed to villagers. The long-established order of society was no longer taken for granted. Electricity and the motorcar were steadily operating tomake "village life¡± and "town life¡± almost alike. Now with the highly developed science and technology and high-level social welfare for all, there is no point whatever in talking any longer about "village life. "It is just life, and that a better life.¡±Finally, if we have any doubts about the future, or about the many changes, which we have seen in our lives, we have only to look in at the school playground any mid - morning; or see the children as they walk homeward in little groups. Obviously these children are better fed, better clothed, better educated, healthier, prettier and happier than any generation of children that ever before walked the village street.1. By saying that village is not dead, but "village life¡±is dead, the writer suggests that_________A. those young people who talk of the village as being "dead¡± are wrongB the two statements are against each otherC. "village life¡± today is rather uninterestingD. "village life¡± today is no longer like what is used to be.2. It was _________ that "village life¡± began to take a sharp turn.A. about a century agoB. during the two world warsC. with electricity and motorcars introduced into the villageD. only recently3. As is suggested in paragraph 2, villagers in the past _________A. lived a simpler life than villagers todayB. knew fewer people than villagers today.C. found it difficult to enjoy themselvesD. liked to wash themselves with cold water.4. The expression "There is no point whatever in talking about¡¡±in paragraph 3 means that_________A. there is no end to the talking about....B. It is harmful to talk about¡.C. It is not meaningless to talk about....D. there is no reason for talking about5. From the passage we can see that the writer's attitude toward "village life¡± is ___________A. positiveB. negativeC. neutralD. unclearPassage 3Pepys and his wife had asked some friends to dinner on Sunday, September 2nd, 1666. They were up very late on the Saturday evening, getting everything ready for the next day, and while they were busy they saw the glow of a fire start in the sky. By 3 o'clock on the Sunday morning, its glow had become so bright that Jane woke her husband to watch it. Pepys slipped on his dressing-gown and went to the window to watch it. It seemed fairly far away, o after a time he went back to bed. When he got up in the morning, it looked, as though the fire was dying down, though he could still see some flames. So he set to work to tidy his room and put his things back where he wanted them.While he was doing this, Jane came in to say that she had heard the fire was a bad one; hundred houses had been burned down in the night and he fire was still burning. Pepys went out to see for himself. He went to the Tower of London and climbed up ¡®on a high part of the buildings so that he could see what was happening. From there, Pepys could see that it was, indeed, a bad fire and that even the houses on London Bridge were burning. The man of the Tower told him that the fire had started in a baker's shop in Pudding Lane; the baker's house had caught fire from the over- heated oven and then the flames had quickly spread to the other houses in the narrow lane. So began the Great Fire of London, a fire that lasted nearly five days, destroyed most of the old city and ended, so it is said, at Pie Corner.1. What is the passage about?A. The Great Fire of London.B. Who was the first to discover the fire?C. What Pepys was doing during the fire.D. The losses caused by the fire.2. They were up very late because ________.A. it was Sunday morningB. they were not very sleepyC. they were preparing for the dinner.D. they saw the great fire start.3. What was Pepys doing when his wife told him about the fire?A. He was asleep.B. He was writing something.C. He was putting things back.D. He was looking out of the window.4. "Pepys slipped on his dressing gown.¡± " To slip on¡± means ________.A. to be wearingB. to be pushingC. to take offD. to put on5. Why did the flames spread quickly?A. The oven became very hot.B. The houses were close together.C. The baker did nothing to stop it.D. The baker's house was burning quickly.Passage 4During the American War of Independence, women were involved in the active fighting in three ways. First, as members of a distinct branch of the Continental Army, referred to as "Women of the Army¡±, women worked in field hospitals and acted as military support in such roles as water carriers. In an emergency (½ô¼±Ê±¿Ì), women water carriers, who had plenty of opportunity to observe the firing of cannons, could replace a wounded comrade. The second way that women were involved in active fighting was as regular troop members who wore men's uniforms and fought side by side with their male counterparts. Theoretically, women were not supposed to be recruited into the Continental Army, but if a woman was a good soldier, no one made an issue of sex at a time when the army was so short of soldiers that boys not yet in their teens were also being recruited in violation of rules. Third, women were occasional fighters affiliated with local militia (ÃñÍÅ) companies or committees of safety formed to protect the local community.第 11 页 共 11 页 1.What is the main idea of the passage?A. Women played an important role in military hospitals during the Revolutionary War.B. The Continental Army was successful in teaching women to fire cannons.C. The services of women on committees of safety were crucial in winning the war.D. Women were active in combat during the revolutionary War. 2.Women sometimes fired cannons in battle because .A. they had observed the procedure and could therefore take the place of the disable men.B. local militia companies had trained them very carefully for emergence fighting.C. they had a better safety record than men for using weapons.D. it was against the law of young boys to fire weapons, 3.

第2次作业一、阅读理解(本大题共100分,共5小题,每小题20分) 1.Prehistoric men and women enjoyed a more varied diet than people do now, since they ate species of plant and several hundreds thousands types of living things. But only a tiny percentage of these were ever domesticated. Modern shops have hastened a trend towards specialization which began in the earliest days of agriculture. The food of the rich countries has become cheaper relative to wages. It is speedily distributed in supermarkets. But the choice annually becomes less and less great. Even individual foods themselves become more standardized. We live in theworld of carrot specially blunted in order to avoid making a hole in the bag, and the tomato grown to meet a demand for a standard weight of weighting tomatoes to a kilo. Siri von Reis asks: "Only the three major cereals (谷物类食物)and perhaps ten other widely cultivated species stand between famine and survival for the world" s human population and a handful of drug plants has served Western civilization for several thousand years. A rather obvious question arises: Are we missing something?” After all, there are 800 000 species of plant on earth.(1). Tn prehistoric times people.A.ate much more than we do todayB.lived mainly on plant foodC.had a wide-ranging dietD.were more fussy about what they ate(2).Most of us have come to expectA.no variation in our dietB. a reduction in food suppliesC. a specialist dietD.food conforming to a set standard(3). The specialization of food was started byA .B . the emergence of supermarkets the rise of agriculture the rich countries the modern shops (4).According to the passage, people in the West today survive on.A.carrots and tomatoesB.several thousand types of plants and cerealsc.a very small number of cultivated foodsD. special species planted one thousand years ago(5). The conclusion seems to be that we.A.could make use of more natural speciesB.don't cultivate the right kind of foodc.produce more food than we needD.cultivate too many different species2.human body is distributed (分布)in two different ways. Some fat people have a large chest and no waistline(腰身),looking rather like apples. Others are fatter below the waist, looking more like pears.Doctors in Cambridge, England have been examining the relationship between health and fat (脂肪)distribution. They find that the pear- shaped fat people have fewer problems than the apple-shaped fat people. What seems to be most important is not how much fat you have but where you have it. The doctors measured the apple-shaped women and peai,--shaped women with X-ray scanners (X 光扫描器).Human beingshave two types of fat:one is outside fat, that is the fat below the skin, and the other is inside fat that lies inside the body. Using the X-ray scanners, the doctors found that the “apples” have a large amoun t of inside fat.Tf this inside fat is much more than outside fat, it wi11 probably cause heal th problems such as obesi ty (月巴月半症). The best treatment for obesity is to reduce the inside fat. But unfortunately diet treatment (饮食疗法)simply makes an apple-shaped person into a smaller apple and a pear-shaped person into a smaller pear. At the moment there is no effective way of reducing the inside fat.(1).According to the relation between heal th and fatnessA.apple-shaped fat people have fewer problems than pear-shaped peopleB.it' s better to be apple-shaped than to be pear-shapedc.it' s better to be pear-shaped than to be apple-shapedD. fatness is the most dangerous enemy to health(2). The most important thing about fat people seems to beA.the amount of fat they haveB.the knowledge of which typo of the fat people they belong toC.the amount of the outside fat they haveD.the place where they have the fat(3).The basic reason why some people suffer from obesity is that •A.they take very little exercise every dayB.they have much more inside fat than is neededc.they are examined by X-ray scanners quite oftenD.they eat too much(4).According to what is mentioned in the passage, the best treatment for obesity at present is .A.to reduce the amount of food and drinksB.to make the body shape smallerC.already known to those people in troubleD.still to be found.3.University of Arizona researcher Dr. William Rathji says that after a study based on looking into garbage cans, the average family wastes at least $150 per year in food."Homemakers go out of their way to save pennies at the store and thendon't real ize that waste of edible (可食用的)foods adds up much moreat homo," said Dr. Rathji. He was one of about 100 food experts who metin Boise for a conference on food waste and ways to prevent it.American families throw out between 8% and 20% of edible food at a costof $4. 5 billion per year. That" s almost as much as the federal government spends every year for food stamps and child nutrition programs.He found that food items which are costly and in short supply tend to be wasted more. During the 1973 meat shortage, meat waste increased to 9%, compared with 3% in 1974 and 1975. Sugar and sugar products waste jumped to 19% in 1975, when sugar prices doubled from the previous year.Dr. Rathji theorizes that high prices force consumers to experiment, sometimes buy in large quantities. In the case of meat, sometimes low-priced cuts for unappetizing varieties are purchased, consumers then tend to waste more.Ilis theory is that the more variety in food bought, the more wasted. Regular bread is wasted at about a 10% rate, but specialty breads and rolls are wasted at a 20% rate.If people are eating the same thing every day, they learn how to manage it. But if you" re trying to pull something out of the cookbook every night, that's bound to be some waste.Another finding is that lower income families waste less food than middle and upper income families. And the study found that dog food, which accounts for 8% of a shopping cart, is rarely wasted. Fresh produce and frozen items arc more likely to be wasted.The study also showed people with the most knowledge of safe, edible food waste the least. Much food is tossed out because a homemaker suspects it is spoiled when it is not.(1).Large quantities of food are thrown out because a homemaker.A.thinks they are not deliciousB.says they taste bitter and hotC.thinks they smell badD.suspects they are spoiled when they are not(2).American families throw out between of edible food every year.A.5%〜8%B.8%-10%B.20%〜28%D.8%—20%(3).When sugar prices doubled, waste of sugar.A.went downB.went upc.stayed the sameD. was cut in half(4).Which of the following statements is true?A.American housewives are not good homemakers.B.Upper-income families are more wasteful than lower-income ones.c.American families throw away almost as much food as they consume.D.Americans waste a great deal of dog food.(5).When do American families waste more food?A.When prices arc high.B.When food is scarce.c.When they think it is spoiled.D. Al 1 of the above.4.Harvard University named historian Drew Gilpin Faust as its first female president on Sunday, ending a lengthy and secretive search to find a successor (接任者)to Lawrence Summers .The seven-member Harvard Corporation elected Faust, a noted scholar on History of the American South and dean of Harvards Radcliffe Institutefor Advanced Study, as the university' s 28th president.“This is a great day, and a historic day for Harvard. ” James R. Houghton, chairman of the presidential search committee, said in a statement. "Drew Faust is an inspiring and accomplished leader, a superb scholar, a dedicated (献身的)teacher, and a wonderful human being."Her selection is noteworthy given the heated debates over Summers' comments that genetic differences between the sexes might help explain the lack of women in top science jobs.Faust has been dean of Radcliffe since 2001, two years after the former women" s college was combined into the university as a research center with a mission to study gender issues(性另ij问题).Some professors have quietly groused that the 371-year-old university is appointing a fifth president who is not a scientist. No scientist has had the top job since James Bryant Conant retired in 1953; its last four have come from the fields of classics, 1aw, literature and economics.Faust is the first Harvard president who did not receive a degree from the university since Charles Chauncy, a graduate of Cambridge University, who died in office in 1762. She attended the University of Pennsylvania.“Teaching staff turned to her constantly. ” said Sheldon Hackney, a former president of the University of Pennsylvania and historian who worked closely with Faust. "She' s very clear. She has a sense of humor, but she' s very strong-minded. You come to trust in her because she' s so solid."(1).Which is NOT true about Drew Gilpin Faust?A.She is the 28th president of Harvard University.B.She is a famous scholar from the American South.c.She isn' t a graduate from Harvard University.D.She was head of Radcliffe Institute for Advanced Study.(2).Lawrence Summers held the view that .A.women cannot achieve as much as men in management B.women cannot hold important positions in society c.women can match men in science jobsD.few women make top scientists owing to genes (3).Which might be the best title for the passage? A.Harvard named its 1st female president.B.History of Harvard University changed.c.Debates on female equality ended.D.Drew GiIpin Faust, a famous woman historian.(4).This passage probably appears in a .A.biographyB.personal letterc.research paperD.newspaper report5.Jessica Alba rebelled(叛离)from her "strict" parents when she was just five. The 29-year-old actress admits her Catholic (天主教)education made her want to "break away" from her mother Catherine and father Mark.She explained: 〃It‘s always been weird(古怪的)because I grew up in a very traditional, Catholic household. Nly parents were very strict but 1 broke away from that at an early age. 1 was a feminist (女权主义者)when 1 was five. These days, 1 am much more independent but 1 still respect their beliefs.,zAs Jessica has grown older she has learnt to accept her parents' views, but still considers herself an independent woman.Tn her latest film 'Machete' Jessica gets to stab(刺)a love rival in the eye with her stiletto heels (鞋后世艮),something she thoroughlyenjoyed.She said: "Walking in 3in heels wasn't as much fun as putting one in someone's eye. It was 104 degrees where we were shooting in Texas and they were not comfortable.Jessica - who has a two-year-old daughter Honor with husband Cash Warren - is regularly referred to as one of the world,s most beautiful women, but she docsn't think of herself as 〃sexy〃.She added in an interview with the Metro newspaper: 〃1 don't really pay attention to that sexy image. It just goes with the character in the movie. At the end of the day, it's all a part of selling a product. 〃(1).Jessica Alba called herself feminist because .A.she didn' t like living with her parentsB.she was brought up in a very poor familyc.she was often against her parentsD.she refused the training and education during her childhood by her parents(2).From this passage we know that .A.Jessica is a very cruel woman who enjoys hurting others B.Jessica acted strangely in her chi 1drenc.Jessica" s parents believe in CatholicD.Jessica rebelled her family because she hated Catholic (3).This passage is mainly about .A.a rebellious movie star JessicaB.a weird womanc.an interview with a newspaperD.a rebellious heart(4).Which of the following statements is not true according to the passage?A.Although she is a rebellious woman, she still respects her parents beliefsB.She likes her characters in the moviec.She cares more about her sexy image because she is very proud of her beautyD.She got married and has a daughter.答案:一、阅读理解(100分,共5题,每小题20分)(1).

2-2. 合金相图反映一些什么关系? 应用时要注意哪些方面的问题? 合金相图反映了合金系中合金状态、温度、成份之间的关系。

合金相图是在极其缓慢加热或冷却条件下(平衡状态)测定的,而实际生产条件下合金的加热冷却都很快(满足不了平衡条件),应用时要注意的问题:
(1) 注意在非平衡状态可能出现的相及组织。

(2) 相图只给出合金在平衡状态下存在的相、相的成份及相对量,并不能反
映相的形状、大小、分布。

(3) 二元相图只反映二元系合金的相平衡关系,它未反映加入其它元素后对
二元系相图的影响。

2.6 铋 (Bi )熔点为271.5℃,锑 (Sb )熔点为630.7℃,两组元液态和固态均无限互溶。

缓冷时=Bi w 50%的合金在520℃开始析出成分为=Sb w 87%的α固相,=Bi w 80%的合金在400℃时开始析出=Sb w 64%的α固相,由以上条件:
⑴ 示意绘出Sb Bi -相图,标出各线和各相区名称;
⑵ 由相图确定Sb w = 40%合金的开始结晶和结晶终了温度,并求出它在
400℃时的平衡相成分和相的质量分数。

解答:1)根据已知条件“两组元液态和固态均无限互溶”可知B i —S b 合金系冷却时发生匀晶反应,构成匀晶相图
先建立横坐标为含S b %,纵坐标为温度的坐标系;
根据第一个已知条件“缓冷时W B i =50%的合金在520℃时开始
析出成分为W S b =87%的α固相”在坐标系中纵坐标为520℃处绘出一条水平线与成分分别为50%和87%的两条铅垂线相交于两点,第一点a 1为液相线上的点,第二点b 1为固相线上的点;同理根据第二个已知条件“W B i =80%的合金在 400℃时开始析出W S b =64%的α固相”得到两点a 2、b 2;
在含S b 为0%的坐标轴上绘出B i 的熔点271.5℃为b 点,在含S b 为100%的纵坐标轴上绘出S b 的熔点630.7℃为a 点,连接a —a 1—a 2—b 得到液相线,连接a —b 1—b 2—b 得到固相线,a —a 1—a 2—b 以上为L 相区,
a —
b 1—b 2—b 以下为α相区,a —a 1—a 2—b 和a —b 1—b 2—b 之间为L +α两相区这样,B i —S b 相图绘制完毕。

过40%成分点作铅垂线交液相线a —a 1—a 2—b 于a 3点和固相线a —b 1—b 2—b 于b 3点,过a 3、b 3作水平线交纵轴得到含S b 40%合金的开始结晶温度约为490℃,结晶终了温度约为325℃。

根据相图得到其在400℃时的平衡相成分为:L 相为20%,α相为64%; 利用杠杆定律可计算出质量分数为:L %= ((64%-40%)/(64%-20%))×100%=54.5%
α%=1-L %=45.5%
2.7 ★若Sn Pb -合金相图(图2.8)中f 、c 、d 、e 、g 点的合金成分分别是Sn w 等于2%、19%、61%、97%和99%。

问在下列温度(t )时,=Sn w 30%的合金显微组织中有哪些相组成物和组织组成物?它们的相对质量百分数是否可用杠杆定律计算?是多少?
⑴t =300℃;⑵刚冷到183℃共晶转变尚没开始;⑶在183℃共晶转变正在进行中;⑷共晶转变刚完,温度仍在 183℃时;⑸冷却到室温时(20℃)。

由下图所示
⑴t =300℃时:=Sn w 30%的合金相当于合金Ⅲ,因其与t =300℃的水平线的交点处于液相区,因此该合金只有100%的液相。

⑵刚冷到183℃共晶转变尚没开始时:合金由α+L 两相组成,
可用杠杆定律计算如下:
⑶在183℃共晶转变正在进行中:相组成物:βα++L 三相共存;组织组成物:L +)(βαα++;不能用杠杆定律计算其相对质量百分数。

⑷共晶转变刚完,温度仍在 183℃时:
相组成物:α和β两相,其相对质量百分数用杠杆定律计算如下:
组织组成物:)(β+α+α,其相对质量百分数用杠杆定律计算如下: ⑸冷却到室温时(20℃):
