2013年5月北京地区成人英语三级考试真题及答案详解Passage1Questions 1 to 5 are based on the following passage:Is that 6 a.m. workout getting in the way of good sleep? Don’t think yourfat cells won’t notice. A new study published in The Annals of Internal Medicine (a medical journal) finds thatinadequate shut-eye has a harmful effect on fat cells, reducing their abilityto respond to insulin (胰岛素) by about 30 percent. Overthe long-term, this decreased response could set the stage for type-2 diabetes(a medical condition in which someone has too much sugar in his or her blood),fatty liver disease and weight gain.The study adds to a growing body of evidence that there’s “an intimaterelationship between the amount of sleep we get and our ability to maintain agood, healthy body weight,” says sleep expert Helene Emsellem, director of theCenter for Sleep and Wake Disorders in Chevy Chase, Maryland. (76) ButAmericans don’t seem to be getting the message that we need seven to nine hoursper night. More than 1 in 5 of us, according to a report from the Centersfor Disease Control and Prevention, is getting six or fewer hours of sleep pernight, on average.So how did researchers study fat cells in the Annals paper? Matthew Bradyof the University of Chicago and a group of colleagues selected and persuadedseven volunteers to take part in the research project. They were all young,thin and healthy and agreed to sleep for eight nights in a sleep lab. “For fournights they were allowed to stay in bed for 8.5 hours a night,” says Brady.Then, a month late r, they came back for four additional nights—but this timethey were allowed just 4.5 hours of sleep per night. And after each visit,researchers got a sample of their fat. (77) Brady explains that the fatcells responded significantly to the loss of sleep. “I was very surprised tobe honest,” he says.Bad things can happen when fat cells become less responsive to insulin.“Fat cells are actually your friend,” he says. “They’re there to store lipids (血脂).” when lipidsstay inside the cells, your body can utilize the fat when you’re exercising orsleeping or going about your day. “However, when fat cells start to becomeinsulin resistant, the lipids start to leach out of the fat cells and rise inthe bloodstream,” Brady says.1. According to the passage, lack of sleepfor a long while can probably lead to all of the following EXCEPT_____.A. heart diseaseB. weight gainC. diabetesD. liver disease2. The main idea of the third paragraph is_____.A. how to write a medical research paperB. how to avoid sleep lossC. how the research was conductedD. how to conduct a medical experiment3. What does the word “leach” in the lastparagraph probably mean?A. Leap.B. Lead.C. Lean.D. Leak.4. Which of the following is NOT TRUEaccording to the passage?A. We will be in trouble if our fat cells becomeless responsive to insulin.B. More and more studies are done to study the linkbetween sleep and weight.C. More than 20% of Americans are not gettingenough sleep.D. Fat cells are there to help us maintain a goodhealth.5. Which of the following is an appropriatetitle for this passage?A. Poor Sleep May Lead to Too Much Stored Fat andDiseaseB. Sleep Experts Had Exciting Findings in a FatStudyC. Americans Should Have More Than Six Hours ofSleepD. Bad Things Happen if Fat Cells Become Our FriendPassage 2Questions 6 to 10 are based on the following passage:The top of the world is a wonderland. In winter, the temperature oftenfalls to -30° F and the sun never rises. The ocean is surrounded by frozenground. There are few people or trees, but to polar bears, the Arctic (北极) is home.(78) Polar bears have thick fur, big paws and other featuresthat make them well prepared for life in their tough environment. In fact, theyneed the Arctic sea ice for survival. But climate change is causing larger andlarger areas of summer sea ice to melt (融化). Experts say that ifwarming patterns continue, the Arctic could be free of summer sea ice by 2050.That may cause two-thirds of the world’s 20,000 polar bears to be gone by thentoo.Polar bears can’t survive for long on land. Seals are their main sourceof food. The only place where polar bears can hunt seals is on the ice. (79)Although these bears are strong swimmers, they are no match for lightning swiftseals in the water. A polar bear has brilliantly clever strategies toovercome this disadvantage. In winter the bear waits motionless beside a seal’sbreathing hole, which is a narrow tunnel through the ice. Often many hours passbefore the seal comes up for air and the bear kills it with a powerful blow ofits paw. In summer, the polar bears that live on land eat very little and waitfor the sea ice to return.With the sea ice forming later in the year and melting earlier, polarbears do not have enough opportunity to hunt and eat. Less sea ice makes itharder for the bears to catch the seals. The bears must swim longer distancesbetween ice packs (大片浮冰), and they can’t always make it. The ice is also gettingthinner. These conditions can causepolar-bear cubs to become separated from their mothers, who provide them withfood. Steven Amstrup is the chief scientist of Polar Bears International. Thegroup aims to save the bears and their home. “The more people who see polarbears and understand their difficult situation, the better th e chance we’llalter our warming path in time to save them,” he says.6. Which is the best title for the passage?A. Climate change in the ArcticB. How to protect the EnvironmentC. The Arctic Is Home to Polar BearsD. Polar Bears in Danger7. Where do polar bears usually hunt seals?A. On land.B. In open water.C. In openings in the sea ice.D. At the bottom of the sea.8. The word “cubs” in the fourth paragraphis closest in meaning to____.A. adultsB. babiesC. huntersD. enemies9. According to the passage, which of thefollowing statements is TRUE?A. Starving polar bears are increasingly cominginto villages, where they may be killed either for food or safety.B. Polar bears can spend their entire lives on landif the sea ice melts completely.C. Two-thi rds of the world’s polar bears maydisappear by 2050 as global warming continues.D. The growing distance between ice packs is not aproblem for polar bears, because they are excellent swimmers.10. What’s the mission of Polar BearsInternational?A. Saving energy.B. Conducting scientific research.C. Seeking international cooperation.D. Saving polar bears and their home.Passage 3Questions 11 to 15 are based on the following passage:Imagine a school that expected its students to become literate (有读写能力的) without any formalinstruction. Most parents would be alarmed by such an approach, which wouldleave their children confused and with gaps in their understanding. Thishowever has been the philosophy on character development in many of ourschools. Why is the development of character seen as somehow different from theother skills that we teach?Of course there will always be learning by osmosis (耳濡目染) in any school,but as a teacher and primary school head I have found that a child’s moralliteracy is s trengthened when they acquire the building blocks of goodcharacter such as consideration, courage and honor: qualities which arecommonly known as virtue (美德).I personally find that exploring a virtue over a two-week period providesa simple and effective program that allows for the creative input of bothteacher and student and a chance for the virtue to embed (使融入) itself. Once alesson on a virtue such as honesty has been completed we need to allow time forchildren to practice this concept just as would be the case with fractions orverbs. Allowing children to role play a situation such asmaking up excuses tocover a mistake can be enormously interesting, and the drama can be frozen allowingthe characters to be questioned about their feelings and motives. (80) It’salso a safe way for children to experience for themselves how a lie usuallygoes out of control.Our role as educators is also to look for opportunities to help ourstudents as they attempt to strengthen their characters. When something goeswrong we guide the young person to the virtue that will prevent it fromhappening again. For instance, when a student thoughtlessly disturbs the calmatmosphere of the library, instead of a response such as, “that was reallydisrespectful and selfish of you!” we draw ou t from them the required virtue:“When you’re walking through the library, what virtues do you need to use?”11. Which of the following is the main ideaof this passage?A. Teaching morals and values has been a frequentlydiscussed topic in the past few years.B. The author and his staff embed virtues intolessons and school life to encourage character development in children.C. Kids throughout the population face the sameneeds, the same challenges, and the same realities in their lives.D. Role plays are an excellent way of gettingstudents to practice their English.12. We can infer from the first paragraphthat_____.A. there tends to be disagreement about whatcharacter education isB. most parents are not satisfied with the teachingmethods adopted in schoolsC. the approach to character education is generallyconsidered different from the approaches to other skillsD. more and more schools are adopting strategies toimprove school attendance13. The word “philosophy” in the first paragraph is closest in meaning to_____.A. studyB. subjectC. viewpointD. investigation14. The author is a_____.A. teacherB. librarianC. reporterD. manager15. Which of the following is NOT mentionedin the passage as a way to build character in children?A. Story readings and discussions.B. Osmosis.C. Taking every opportunity to teach character.D.
