Sometimes, when Mr．Ballmer and his 56-year-old daughter, Elizabeth, listen to rock music together and talk about interests both enjoy, such as pop culture, he remembers his more distant relationship with his parents when he was a teenager．‎ ‎"I would-never have said to my mom, 'Hey, the new Weezer album is really great．How do you like it?'" says Ballmer．"There v/as just a complete gap in taste．"‎ Music was not the only gulf．From clothing and hairstyles to activities and expectations, earlier generations of parents and children often appeared to move in separate orbits．‎ Today, the generation gap has not disappeared, but it is getting narrow in many families． Conversations on subjects such as sex and drugs would not have taken place a generation ago．Now they are comfortable and common．And parent—child activities, from shopping to sports, involve a feeling of trust and friendship that can continue into adulthood．‎ No wonder greeting cards today carry the message, "To my mother, my best friend．" ‎ But family experts warn that the new equality can also result in less respect for parents． "There's still a lot of strictness and authority on the part of parents out there, but there is a change happening," says Kerne, a psychology professor at Lebanon Valley College．"In the middle of that change, there is a lot of confusion among parents．"‎ Family researchers offer a variety of reasons for these evolving roles and attitudes．They see the 1960s as a turning point．Great cultural changes led to more open communication and a more democratic process that encourages everyone to have a say．‎ ‎"My parents were on the 'before' side of that change, but today's parents, the 40-year-olds, were on the 'after' side," explains Mr．Ballmer．"It's not something easily accomplished by parents these days, because life is more difficult to understand or deal with, but sharing interests does make it more fun to be a parent now．"‎ ‎51．The underlined word gulf in Para．3 most probably means ______．‎ ‎ A．interest B．distance C．difference D．separation ‎52．Which of the following shows that the generation gap is disappearing?‎ ‎ A．Parents help their children develop interests in more activities．‎ ‎ B．Parents put more trust in their children's abilities．‎ ‎ C．Parents and children talk more about sex and drugs．‎ ‎ D．Parents share more interests with their children．‎ ‎53．The change in today's parent-child relationship is _______．‎ ‎ A．more confusion among parents ‎ B．new equality between parents and children ‎ C．less respect for parents from children ‎ D．more strictness and authority on the part of parents ‎54．By saying "today's parents, the 40-year-olds, were on the 'after' side．" the author means that today's parents ______．‎ ‎ A．follow the trend of the change B．can set a limit to the change ‎ C．fail to take the change seriously D．have little difficulty adjusting to the change ‎55．The purpose of the passage is to _____．‎ ‎ A．describe the difficulties today's parents have met with ‎ B．discuss the development of the parent—child relationship ‎ C．suggest the ways to handle the parent—child relationship ‎ D．compare today's parent—child relationship with that in the past B Scientific experiments can sometimes go wrong and when they do the results may range from the disastrous to the troubling．One such experiment took place in South America about fifty years ago．Whether its final consequences will cause serious damage or nothing more than a small trouble still remains to be seen．‎ The story began in 1956 when an American scientist working in Brazil decided to solve the problem of increasing the productivity of that country's bees．He imported a very active type of African bee from Tanzania and mated （交配） it with the more easy-going native variety to produce a new kind of bees．The new bees worked harder and produced twice as much honey．It seemed that Professor Kerr, for that was the scientist's name, had a total success on his hands．‎ Then things began to go wrong．For some reason as yet unseen, but perhaps as a result of something in their environment, the new bees began to develop extremely attacking personalities． They became bad-tempered and easy to be angry, attacked the native bees and drove them from their living places．‎ But worse was to follow．Having taken over the countryside, the new bees, with their dangerous stings （叮）, began to attack its neighbors - cats, dogs, horses, chickens and finally man himself．A long period of terror- began that has so far killed a great number of animals and about 150 human beings．‎ This would have been bad enough if the bees had stayed in Brazil．But now they are on the move, heading northwards in countless millions towards Central and North America, and moving at the alarming speed of 200 miles a year．The countries that lie in their path are naturally worried because it looks as if nothing can be done to stop them．‎ ‎56．The results of the South American experiment ______ ．‎ ‎ A．have caused a serious trouble B．have proved to be wrong ‎ C．are not yet certain D．are not important ‎57．The experiment mentioned in this passage was designed to ______ ．‎ ‎ A．increase the amount of honey in Brazil B．make Brazilian bees more easy-going ‎ C．increase the number of bees in Brazil D．make African bees less active ‎58．Which of the following may be the cause of the new bees' attacking personalities?‎ ‎ A．Their production of honey． B．Their hard work．‎ ‎ C．Their living environment． D．Their bad temper．‎ ‎59．The last paragraph implies that ______ ．‎ ‎ A．the bees have been driven to Central and ‎North America ‎ B． the bees may bring about trouble in more countries ‎ C．the bees must be stopped from moving north ‎ D．the bees prefer to live in ‎Brazil C ‎ （You may read the questions first,）‎ ‎60．The Fresh Water series at 9 AM _____．‎ ‎ A．explores the lakes, rivers and the creatures in them ‎ B．is devoted to the freshwater creatures in the world ‎ C．explains the relationship among inhabitants on the earth ‎ D．focuses on the deepest river on the planet ‎61．The phrase "stow away" most probably means "______"．‎ ‎ A．hide secretly B．talk excitedly ‎ C．operate easily D．guide successfully ‎62．A mystery story adapted from Agatha Christie's novel will be shown on _____．‎ ‎ A．BBC1 B．BBC‎2 ‎ C．ITV1 D．Channel 4‎ D Do you want to live with a strong sense of peacefulness, happiness, goodness, and self respect? The collection of happiness actions broadly categorized as "honor" help you create this life of good feelings．‎ ‎ Here's an example to show how honorable actions create happiness．‎ Say a store clerk fails to charge us for an item．If we keep silent, and profit from the clerk's mistake, we would drive home with a sense of sneaky excitement．Later we might tell our family or friends about our good fortune．On the other hand, if we tell the clerk about the uncharged item, the clerk would be grateful and thank us for our honesty．We would leave the store with a quiet sense of honor that we might never share with another soul．‎ ‎ Then, what is it to do with our sense of happiness?‎ In the first case, where we don't tell the clerk, a couple of things would happen．Deep down inside we would know ourselves as a type of thief．In the process, we would lose some peace of mind and self-respect．We would also demonstrate that we cannot lie trusted, since we advertise our dishonor by telling our family and friends．We damage our own reputations by telling others．In contrast, bringing the error to the clerk's attention causes different things to happen．Immediately the clerk knows us to be honorable．Upon leaving the store, we feel honorable and our self-respect is increased．Whenever we take honorable action we gain the deep internal rewards of goodness and a sense of nobility．‎ There is a beautiful positive cycle that is created by living a life of honorable actions．Honorable thoughts lead to honorable actions．Honorable actions lead us to a happier existence． And it's easy to think and act honorably again when we're happy．While the positive cycle can be difficult to start, once it's started, it's easy to continue．Keeping on doing good deeds brings us peace of mind, which is important for our happiness．‎ ‎63．According to the passage, the positive action in the example contributes to our____．‎ ‎ A．self-respect B．financial rewards ‎ ‎ C．advertising ability D．friendly relationship ‎64．The author thinks that keeping silent about the uncharged item is equal to____．‎ ‎ A．lying B, stealing C．cheating D．advertising ‎65．The phrase "bringing the error to the clerk's attention" （in para．5） means_ .‎ ‎ A．telling the truth to the clerk ‎ B．offering advice to the clerk ‎ C．asking the clerk to be more attentive ‎ D．reminding the clerk of the charged item ‎66．How will we feel if we let the clerk know her mistake?‎ ‎ A．We'll be very excited． B．We'll feel unfortunate．‎ ‎ C．We'll have a sense of honor． D．We'll feel sorry for the clerk．‎ ‎67．Which of the following can be the best title of this passage．?‎ ‎ A．How to Live Truthfully ‎ B．Importance of Peacefulness ‎ C．Ways of Gaining Self-respect ‎ D．Happiness through Honorable Actions E As a professor at a large American university, there is a phrase that I hear often from students: "I'm only a 1050．" The unlucky students are speaking of the score on the Scholastic Aptitude Test （SAT）, which is used to determine whether they will be admitted to the college or university of their choice, or even have a chance to get a higher education at all．The SAT score, whether it is 800, 1100 or 1550, has becomes the focus at this time of their life．‎ It is obvious that if students value highly their test scores, then a great amount of their self-respect is put in the number．Students who perform poorly on the exam are left feeling that it is all over．The low test score, they think, will make it impossible for them to get into a good college．‎ And without a degree from a prestigious university, they fear that many of life's doors will remain forever closed．‎ According to a study done in the 1990s, the SAT is only a reliable indicator of a student's future performance in most cases．Interestingly, it becomes much more accurate when it is set together with other indicators—like a student's high school grades．Even if standardized tests like the SAT could show a student's academic proficiency （学业水平） ．they will never be able to test things like confidence, efforts and willpower, and are unable to give us the full picture of a student's potentialities （潜力） ．This is not to suggest that we should stop using SAT scores in our college admission process．The SAT is an excellent test in many ways, and the score is still a useful means of testing students．However, it should be only one of many methods used．‎ ‎68．The purpose of the SAT is to test students'_ __．‎ ‎ A．strong will B．academic ability ‎ C．full potentialities D．confidence in school work ‎69．Students' self-respect is influenced by their__ _．‎ ‎ A．scores in the SAT ‎ B．achievements in mathematic ‎ C．job opportunities ‎ D．money spent on education ‎70．“A prestigious university" is most probably___ _．‎ ‎ A．a famous university ‎ B．a technical university ‎ C．a traditional university ‎ D．an expensive university 第Ⅱ卷 第四部分 写作（共两节，满分35分；请将第Ⅱ卷旳答案写在答题纸上）‎ 第一节 阅读表达（共5小题，每小题2分，满分10分）‎ 阅读下面旳短文，请根据短文后旳要求答题.（注意字数要求）‎ A punctual person is in the habit of doing a thing at the proper time and is never late in keeping an appointment．‎ The unpunctual man, on one hand, never does what he has to do at the proper time, He is always in a hurry and in the end loses both time and his good name．A lost thing may be found again, but lost time can never be regained．Time is more valuable than material things．In fact, time is life itself．The unpunctual man is for ever wasting and mismanaging his most valuable asset as well as other's．The unpunctual person is always complaining that he finds no time to answer letters, or return cails or keep appointments promptly．But the man who really has a great deal to do is very careful of his time and seldom complains of want of it．He knows that he can not get through his huge amount of work unless he faithfully keeps every piece of work when it has to be attended to．‎ Failure to be punctual in keeping one's appointments is the sign of disrespect towards others． If a person is invited to dinner and arrives later than the appointed time, he keeps all the other guests waiting for him．Usually this will be regarded as a great disrespect to the host and all other guests present．‎ Unpunctuality, moreover, is very harmful when it comes to do one's duty, whether public or private．Imagine how it would be if those who are put in charge of important tasks failed to be at their proper place at the appointed time．A man who is known to be habitually unpunctuai is never trusted by his friends or fellow men．‎ ‎71．What does the author think is the main difference between a punctual person and an unpunctual person? （No more than 20 words）‎ ‎72．According to the passage, the main reason that a person is always unpunctual is that ____．‎ ‎ （No more than 10 words）‎ ‎73．What

This kind of loneliness is not serious. In fad, it is quite normal. For some people, though, loneliness can last for years. Now researchers say there are three different types of loneliness.‎ The first kind of loneliness is temporary. This is the most common type. It usually disappears quickly and does not require any special attention. The second kind, situation—for example, family problem, the death of a loved one, or moving to a new place. Although this kind of loneliness can cause physical problems, such as headaches and sleeplessness, it usually does not last for more than a year.‎ The third kind of loneliness is the most severe. Unlike the second type, chronic (the opposite of "temporary") usually lasts more than two years and has no specific cause. People who experience habitual loneliness have problems socializing and becoming close to others.‎ Unfortunately, many chronically lonely people think there is little or nothing they can do to improve their condition.‎ Psychologists agree that one important factor in loneliness is a person's social contacts, for example, friends, family members, co-workers, etc. we depend on various people for different reasons. For instance, our families give us emotional support, our parents and teachers give us guidance, and our friends share similar interests and activities. However, psychologists have found that, though lonely people may have many social contacts, they sometimes feel they should have more. They question their popularity.‎ Psychologists are trying to find ways to help habitually lonely people for two reasons: they are unhappy and unable to socialize and there is a connection between chronic loneliness and serious illness as heart disease, while temporary and situational loneliness can be a sad, and sometimes dangerous condition.‎ 一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一
