senior-friendly products．They knew they were making history when they coined their company motto : "Of the elderly, by the elderly and for the elderly．" They do not hire young people, and the oldest of their workers is 75．Firms run by senior citizens are still a rarity, in Japan and worldwide．But the elderly have numbers on their side．Healthier and longer-living seniors, born immediately after World War II,are reaching retirement age in huge numbers all over the developed world．Extremely low birthrates in those same countries mean there are far fewer young workers to take their place．One likely con-sequence is now clear: shrinking work forces．While the streamlining effects of international competition are focusing attention on the need to create and keep good jobs, those fears will eventually give way to worries about the growing short-age of young workers．One unavoidable solution: putting older people back to work, whether they like it or not．Indeed, advanced economies like those of Finland and Denmark have already raised their retirement ages．Others are under severe pressure to follow suit, as both the European Com-mission and the Organization for Economic Cooperation and Development have recently warned their members that their future prosperity depends on a growing contribution from the elderly．Whether these changes are good or bad news to workers depends on whether they anticipate retirement with eagerness or dread．In the United States, half of working-age Americans now expect to work into their 70s, whether by financial necessity or by lifestyle choice, according to a new study by Putnam Investments．Contrary to still widespread assumptions, there is very little hard evidence to suggest that com-panies cannot stay competitive with a rising share of older workers．At 13ritish hardware chain B&Q, its "elder worker" stores in Manchester and Exmouth were 18 percent more profitable than its regular outlets--due in part, the company says, to six times

ChoicesC．is not a usual practice among competitive firmsD．is not good news to those who are eager to retire根据下列材料，请回答51-65题：Here' s how I want to watch the 2014 Winter Olympics．I want to go to a Web site to see any event I want, whenever I want to watch it, on whatever screen I choose．I' 11 gladly pay．The technology exists to make this happen today．Yet nearly two decades after the introduction of the World Wide Web, this remains a fantasy．NBC, which broadcasted the Vancouver Olympics in the United States, wouldn' t put videos on its Web site until they had been shown on prime-time TV．So Americans had the weird experience of learning from a news report during the day that something fantastic had just happened, and then having to wait until that night' s broadcast to see it．Bloggers complained, but NBC wouldn' t give way．Its research shows that people like me, who want to watch the Olympics online, represent only 7 percent of the total audience．The other, bigger concern is: the Internet doesn' t deliver any money．Advertisers remain willing to pay big money to show their commercials on prime-time TV．But onthe Internet? Not so much．So NBC clings to the old way of doing things．As it sees it, the prime-time show is the most important．To make matters worse, NBC was already expecting to lose $ 250 million on the 2010 Vancouver Games．Good luck persuading it to invest in a risky Web project．It's easy to blame the network executives．But the NBC guys and their like are only doing what makes sense．They're going where the money is．That needs to change．Yes, selling reporting of Olympic events over the Internet would drain away some of the prime-time audience, but my sense is many of the online subscribers would still watch the prime-time show．And over time, the subscription dollars could become a substantial rev- enue stream．Instead of viewing the Internet as a threat to prime time, the TV networks should see the Web as a way to sell even more of their product to a small but passionate subset of their audi-ence．I' m hoping that by 2014, that will have changed．51、According to the writer, watching the Olympics online as one likesA．is technologically impossibleB．is still denied to the audienceC．has been a dream for 20 yearsD．will no longer be free in 201452、We learn that what Americans saw about the Vancouver OlympicsA．was unavailable onlineB．differed from the newsC．seemed weird to themD．was first shown on TV53、Bloggers complained about NBC' sA．neglect of those in the minorityB．excessive online advertisementsC．delay in providing videos onlineD．limited reporting on sports news54、After the 2010 Vancouver Games, NBC is likely toA．improve its prime-time showB．continue its current practiceC．raise its price for advertisingD．try its luck in a web program55、The writer thinks the TV networks should view the Web as a potential to help them toA．make dramatic profitsB．develop new productsC．satisfy their subscribersD．divide prime-time revenues根据下列材料，请回答56-70题：One important thing during the pre-Christmas rush at our house was the arrival of my daughter' s kindergarten report card．She got high praise for her reading, vocabulary and overall en-thusiasm．On the other hand, we learnt that she has work to do on her numbers and facility with the computer, though the detailed handwritten report her teachers prepared is absent of any words that might be interpreted as negative in describing her efforts．A number system indicates how she' s measuring up in each area without any mention of passing or failing．All of which seems to make my daughter' s school neither fish nor fowl when it comes to the debate over the merits of giving formal grades to kids．At one level, the advantages and disadvanta-ges are obvious．A grade system provides a straightforward standard by which to measure how your child is progressing at school--and how he or she is getting on compared to other children．But as writer Sue Ferguson notes, "Grades can deceive．" The aim should be "to measure learning, not simply what a student can recall on a test．" The two aren' t the same--and if you doubt that as an adult, ask yourself whether you could sit down without any preparation and still pass those high-school-level examinations．If you' re old enough, you' ve lived through this debate before．At one time, it was considered unfair to put children in direct competition with one another if it could be avoided．The inten-tion behind tha．t may have been good, but it ignored the fact that competition, and the will to come out on top, are essential components of the human condition．This time around, educators working with a no-grades approach are emphasizing different rea-sons．The thing is, that approach is much more commonplace in the adult workplace than is the tra-ditional pass-fail system we place on our children．Many workplaces conduct regular employee eval-uations．There are usually fairly strict limits to what an employer can tell an employee in those eval-uations-and even then, negative evaluations can be challenged by the employee．No matter where you sit in the debate over the grade system, then, the real question is this: if it' s so good for kids, why isn't that also true for adults?56、The school report indicates that the writer' s daughterA．lacks interest in her school workB．ranks among the best at languageC．has some trouble with her handwritingD．needs to improve in math and computer skills57、We can learn that the girl' s school tries to deliver the reportA．in a positive wayB．in a scientific wayC．in an attractive wayD．in an enthusiastic way58、Sue Ferguson seems dissatisfied with the grade system for its focus onA．the process of getting the knowledgeB．the capability of memorizing for the testC．the procedure of measuring learningD．the standard of comparing schools59、The writer would agree that cutting children off from competition isA．fit for human developmentB．fit for their age and experienceC．against a key part of human natureD．out of consideration for children60、It can be learned that today's educators supporting the no-grades approach insist thatA．kids be allowed to challenge the negative evaluationsB．the traditional teacher-student relationship be changedC．the evaluation system for kids be similar to that for adultsD．strict rules be set up in evaluating school children61、根据下列材料，请回答61-65题：Directions:Read the texts from a magazine in which five people voice their different opinions in response to an article on theissue of praising．For questions 61 to 65, match the name of each person (61 to 65) to one of the statements ( A to G) given below．Mark your answers on ANSWER SHEET1．Mike :Praise often and sincerely--it' s as simple as that．Employees want to feel needed and appreci-ated．By offering sincere praise with examples about what they did right, you' ll go far in creating an energetic team．Meanwhile, I don't agree with the assertion that "to focus on what needs im-proving isn' t good management．" In fact, it' s the balance of praise along with constructive criti-cism that drives employees to work smarter and reach higher．Frank:This article makes a valid point that needs to be understood, especially for the new generation of workers, my generation．We don' t see ourselves as parts in the machine to be put in the dark to work．My generation needs respect in return from our employer, we need to feel appreciated beyond just a pay check, it' s the difference between being fulfilled at our career and being sad at our job．Joyce :One skill missing in today's workplace is the ability to build effective business relationships．At the core of that relationship is the need for consistent feedback．"How am I doing?" is a ques-tion that should be answered consistently．When you tell an employee once a year what is needed to improve, you have not done your job as a leader--build skills, provide feedback and help the em-ployee grow and develop．Ellen:I don' t see a problem with praising employees when it' s truly deserved ( insincere praise is an entirely different story)．It' s a cost-free "benefit", if you will, in that it allows employees to see that their efforts are both noticed and valued．In the work world there are always people available to tell that you are doing something wrong and far too few occasions when employees are told that they've done something right!Diana:Praise what the employee did．Be specific about why it was helpful．An employee who contin-ually earns yourpraise also deserves your attention as to how else to reward their behavior．Mean-ingful praise encourages people beyond anything else．Written comments are available for later re-view．They give them confidence that they can "do it again．" I never regretted praising an employ-ee who deserved it but often kicked myself for missing an opportunity．Now match the name of each person (61 to 65) to the appropriate statementNote: there are two extra statements．Statements[A]Praise combined with criticism is helpful．[B] Praise can bring about many kinds of desired behavior．[C] Employees may feel it hard to accept．insincere praise．[D] Let employees know exactly for what they are praised．[E] In my opinion, we are not generous enough to give praise．[F] Employees need helpful advice on a regular basis．[G] Money alone cannot guarantee a sense of career fulfillment for me．61、Mike62、Frank63、Joyce64、Ellen65、DianaSECTION IV Writing Part A(40 minutes)66、Directions:You should write your responses to both Part A and Part B of this section on ANSWER SHEET 2．Part AYou will be transferred to the city where your friend James lives．Write an email to him, telling him about:1 ) the reason(s) for your job transfer;2 ) the help you will need from him．You should write approximately 100 words．Do not use your own name at the end of your email．Use "Wang Lin" instead．SECTION IV Writing Part B(40

公共英语三级(pets3)阅读理解精选习题三
A major incentive(动力) for college attendance is the belief that it will prepare you for a career. Chances are that the career you want, whether in nursing, counseling, law, or management, requires a college education. Even if the return of your education isn’t as great as it used to be, you would probably rather be a relatively poorly paid lawyer than a secretary or a construction worker; you would probably rather be a manager than a managee. In the sense that a degree is increasingly required for even middle-level jobs, your investment in a college education will still pay off.It can pay off in other ways too. It is a value judgement to say that a college education will make you a better person, but it is a value judgement that the vast majority of college graduates are willing to make survey after survey to demonstrate that people feel very positive about their college education, believing that it has made them better and more tolerant people.Whether it makes you a better person or not, a college education is likely to have a lasting effect on your knowledge and values. If you finish college, you will sit through 30 to 45 different courses. Even the least dedicated student is bound to learn something from these courses. In addition, students learn informally. Whether you go to college in you hometown or across the country, college will introduce you to a greater diversity of people than you’re likely to have experienced before. This diversity will challenge your mind and broaden your horizons.As a result of formal and informal learning, college graduates are more knowledgeable about the world around them, more tolerant and less prejudiced, more active in public and community affairs, and, more open to new ideas.1. It is apparent from the passage that people go to college mainly because they believe ___.A. a college education will provide them with a guarantee of success in lifeB. the economy of their country can’t absorb an army of untrained youngstersC. a college education will make them better qualified for a careerD. the investment in a college education can bring a higher economic return than before2. We can learn from the second paragraph that ___.A. college can hardly help people become better citizensB. most college graduates refuse to make any comment on their college educationC.a college education may not be the best thing for everyoneD. people consider their college education to be of great worth3. The word “dedicated”(Para. 3) could best be replaced by ___.A. hardworkingB. competentC. intelligentD. conservative4. According to the passage, which of the following statements is NOT true?A. A college student can enrich his knowledge and broaden his mind through formal and informal learning.B. A college education is likely to be a required credential(文凭) for the career a person wants.C. A college student who doesn’t work hard can get nothing out of the courses he takes.D. A college education tends to have long-range effects on a person’s knowledge and values.5. This passage is primarily concerned with ___.A. the change of people’s attitude toward their college educationB. the benefits of a college educationC. the result of formal and informal learningD. the intercommunication among college students1. 【精析】C事实细节题。
