But now scientists are giving this feeling an empirical(实证的) basis. They are discovering how to design spaces that 41 creativity, keep people focused and relaxed.Researches show that aspects of the physical environment can 42 creativity. In 2007, Joan Meyers-Levy at the University of Minnesota, reported that the height of a room’s ceiling affects how people think. Her research indicates that higher ceilings encourage people to think more freely, which may 43 them to make more abstract connections. Low ceilings, on the other hand, may inspire a more detailed outlook.In addition to ceiling height, the view 44 by a building may influence an occupant’s ability to concentrate. Nancy Wells and her colleagues at Cornell University found in their study that kids who experienced the greatest increase in greenness as a result of a family move made the most 45 on a standard test of attention. Studies show that students in classrooms with 46 views of at least 50 feet outside the window had higher scores on tests of vocabulary, language arts and maths than did students whose classrooms primarily 47 roads and parking lots.Recent study on room lighting design suggests that dim light helps people to loosen up. If thatis 48 generally, keeping the light low during dinner or at parties could increase 49 . Researchers of Harvard Medical School also discovered that furniture with rounded edges could help visitors relax.III. Reading ComprehensionSection ADirections: For each blank in the following passage there are four words or phrases marked A, B, C and D. Fill in each blank with the word or phrase that best fits the context.Much time and effort has been devoted to researching the mental health benefits of flexible work environments, but can the ability to leave work early to watch your son’s soccer game, or arrive at theoffice a bit later in the morning in order to 50 some personal matters, have broader physical health benefits 51 making you feel a bit less tired?According to new research published in the Cochrane Library's Cochrane Database of Systematic Reviews, it seems so. In a review of 10 previous studies examining the health effects of flexible work conditions for more than 16,000 people, 52 from the U.K.'s Durham University and University of Newcastle, as well as the University of Montreal, found that flexible work schedules — when employees can 53 their starting times, for example — were associated wit h improvements in a person’s overall health. And, perhaps unsurprisingly, in all of the studies included in the review, researchers found no evidencefor 54 effects of more flexible work schedules.This initial analysis was intended to throw light on the potential health benefits of flexible work options, which are increasingly 55 throughout Scandinavia, and have recently gained some ground in the U.K. 56 , last April, the British government 57 a policy that allowed parents of children ages six and under to request flexible work arrangements to include parents of children ages 16 and younger. In the U.S., the phenomenon is a bit slower to catch on. Yet, the economic slowdown of recent years may have contributed to 58 in workplace flexibility — as companies 59 to reward employees with bonuses(奖金) or raises may 60 other forms of compensation(补偿), Reuters reported early last year.Previous research too, of course, has indicated the benefits of flexible work environments toward positive mental health outcomes. And while these latest findings are promising, the researchers stress that more study is vital to understanding the detailed 61 between flexible work and improved health outcomes. To truly 62 the benefits of flexible working conditions, the researchers say, additional study analyzing health outcomes among a wide 63 of workers — from high-ranking executives to hourly employees — is 64 , which helps to gain a deeper understanding of the issue, and to shape future workplace policy.50. A. see to B. keep to C. point to D. look to51. A. across B. besides C. before D. over52. A. officials B. employers C. executives D. researchers53. A. spend B. devote C. shift D. cancel54.

A. critical B. possible C. feasible D. demandingSection BDirections: Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.（A）A special education teacher and former police officer was honored by President Barack Obama at the White House as the 2009 National Teacher of the Year for his innovative approach, community focus, and teamwork with other teachers. “In a global economy where the greatest job qualification isn’t what yo u can do, but what you know, our teachers are the key to our nation’s success,” President Obama stated.Mullen, a ninth-through twelfth-grade special education teacher at the ARCH School in Connecticut, is the 59th National Teacher of the Year. Mullen’s go al is to provide passion, professionalism, and perseverance as an educator. “A teacher can receive no greater reward than the knowledge that he or she helped recover a lost student,” Mullen remarked. He will travel for one year as a full-time national and international spokesperson for education beginning June 1, 2009.The National Teacher of the Year Program focuses public attention on teaching excellence and is the oldest and most famous national honors program for teachers. “ACEI is a proud participant i n the selection process for the National Teacher of the Year, and we are pleased to see Anthony Mullen selected. Mr. Mullen is a dedicated individual who possesses a wealth of talents and skills as a teacher. His devotion to young people, however, reaches beyond the call of duty. Mr. Mullen extends himself to adviser and guides children who need to know that they are not forgotten and that they, too, are unique and special,” stated ACEI Executive Director Diane Whitehead.ACEI is one of 15 national education organizations that select the National Teacher of the Year from among the state teachers of the year, including those representing the District of Columbia, the Department of Defense Education Activity, and five U.S. extra state departments.65. What is the passage mainly about?A. A White House ceremony.B. An innovative teaching approach.C. The 2009 National Teacher of the Year.D. The national education organizations.66. We can learn from the first paragraph Obama stresses ____________.A. teac hers’ roleB. community livesC. teachers’ teamworkD. innovative approach67. It can be inferred from the passage that ___________.A. the National Teacher of the Year Program hasn’t been well-knownB. ACEI is the only organization in charge of selecting excellent teachersC. Mullen is devoted to teaching the students for the call of dutyD. Mullen’s success may be due to his devotion to education.（B）It’s 10 p.m. You may not know where your child is, but the chip does.The chip will also know if your child has fallen and needs immediate help. Once doctors arrive, the chip will also be able to tell them which drugs are not suitable for little Jonny or Janie. At the hospital, the chip will tell doctors his or her complete medical history. And of course, when you arrive to pick up your child, setting the hospital bill with your health insurance policy will be a simple matter of waving your own chip ___ the one embedded(植入) in your hand.To some, this may sound unbelievable. But the technology for such chips is no longer the stuff of science fiction. And it may soon offer many other benefits besides locating lost children or elderly patients. It could be used as credit cards and people won’t have to carry wallets anymore.On the other hand, some are already wondering what this sort of technology may do to the sense of personal privacy and liberty.“Any technology of this kind could result in abuse of personal privacy,” says Lee Tien, senior staff lawyer for the Electronic Frontier Found ation. “If a kid can be tracked, do you want other people to be able to track your kid? It’s a double-edged sword.”Applied Digital Solutions, Inc. in Palm Beach, Florida, says it has recently applied to the Food and Drug Admission for permission to begin testing its device in humans. About the size of a grain of rice, the microchip can be coded with bits of information and embedded in humans under a layer of skin. When scanned by a nearby reader, the embedded chip gives the data.Most embedded chip designs are so-called passive chips, which give information only when scanned by a nearby reader. But active chips ___ such as the proposed Digital Angel of the future ___ will give out information all the time. And that means designers will have to develop some sort of power source that can provide a continuous source of energy, yet be small enough to be embedded with the chips.In addition to technical problems, many suspect that all sorts of legal and privacy issues would have to be cleared as well.68. By using the example in the first two paragraphs, the author wants to tell us that _______.A. chips are usually used to locate lost childrenB. chips are more convenient than credit cardsC. chips will soon be useful in many aspects of daily livesD. chips will bring out the issue of abuse of personal privacy69. What is the attitude of Lee Tien towards the chips?A. NegativeB. PositiveC. IndifferentD. Concerned70. Which of the following statements about Digital Angel is NOT true?A. It will include a chip and a power source.B. It will be produced and replace passive chips.C. It will be embedded in humans under a layer of skin.D. It will give information without being scanned by a reader.71. It is indicated in the passage that chip producers have to consider the following issues EXCEPT_______.A. financial problemsB. technical problemsC. legal problemsD. privacy problem（C）If you don’t have a college degree, you’re at grea ter risk of developing memory problems or even Alzheimer’s (老年痴呆). Education plays a key role in lifelong memory performance and risk for mental disorder, and it's well documented that those with a college degree possess a cognitive（认知的）advantage over those less educated in middle and old age.Now, a large national study from Brandeis University published in the American Journal of Geriatric Psychiatry shows that those with less schooling can significantly make up for poorer education by frequently engaging in mental exercises such as word games, puzzles, reading, and lectures.“The lifelong benefits of higher education for memory in later life are quite impressive, but we do not clearly understand how and why these effects last so long,” said lead author Margie Lachman, a psychologist. She suggested that higher education may encourage lifelong interest in cognitive efforts, while those with less education may not engage as frequently in mental exercises that help keep the memory agile (敏捷地).But education early in adulthood does not appear to be the only route to maintain your memory. The study found that intellectual activities undertaken regularly made a difference. “Among individuals with low education, those who are engaged in reading, writing, attending lectures, doing word games or puzzles once a week or more had memory scores similar to people with more education,” said Lachman.The study, called Midlife in the United States, assessed 3,343 men and women between the ages of 32 and 84 with an average age of 56 years. Almost 40 percent of the participants had at least a 4-year college degree. The researchers evaluated how the participants performed in two cognitive areas, verbal (言语的)memory and executive function --- brain processes involved in planning, abstract thinking and cognitive flexibility. Participants were given a series of tests, including tests of verbal fluency, word recall, and backward counting.As expected, those with higher education said they engaged in cognitive activities more often and also did better on the memory tests, but some with lower education also did well, explained Lachman.“The findings are promising because they suggest there may be ways to level the playing field for those with low er educational achievement, and protect those at greatest risk for memory declines,” said Lachman. “Although we can not rule out the possibility that those who have better memories are the ones who take on more activities, the evidence is consistent with cognitive plasticity (可塑性), and suggests some degree of personal control over cognitive functioning in adulthood by adopting an intellectually active lifestyle.”72. What is the text mainly about?A. Higher education has a better cognitive advantage.B. Better memories result from college degree.C. Cognitive activity does good to one’s mind.D. Poor education has more risk of memory declines.73. According to the result of Margie Lachman’s study, we can conclude that ________.A. education is responsible for the lifelong memory performance and risk for mental disorderB. education early in adulthood can be the only route to maintain your memoryC. those with higher education did better on the memory tests than those with lower educationD. an intellectually active lifestyle does help to maintain your memory74. What do we know about the study called Midlife?A. Participants each were given a battery to test their memory.B. The average age of the participants are 56 years old.C. Participants had to perform in one of the two cognitive areas.D. One in four of the participants had a 4-year college degree.75. Why are the findings of the Lachman’s study promising?A. The lower educated may have the same opportunities to keep up memory.B. We may have ways to cure the people who have memory declines.C. Adopting a different lifestyle can control cognitive functioning.D. We can find out the possibility to have better memories.Section CDirections: Read the following passage and choose the most suitable heading from A—F for each paragraph. There is one extra heading which you do not need.A. Necessity for china-and-silver eleganceB. A new trend towards casual diningC. Preference for traditional diningD. Shrinking of the pottery industryE. Roots of casual diningF. Reasons for the shrinking of the pottery industryWhen families gather for Christmas dinner, some will stick to formal traditions dating back to Grandma’s generation. Their tables will be set with the good dishes and silver, and the dress code will beSunday-best.76.But in many other homes, this china-and-silver elegance has given way to a stoneware(粗陶)-and-stainless informality, with dresses assuming an equally casual-Friday look. For hosts and guests, the change means greater simplicity and comfort. For makers of fine china in Britain, it spells economic hard times.77.Last week Royal Doulton, the largest employer in Stoke-on-Trent, announced that it is eliminating 1,000 jobs — one-fifth of its total workforce. That brings to more than 4,000 the number of positions lost in 18 months in the pottery region. Wedgwood and other pottery factories made cuts earlier.78.Although the increased value of the pound and weak markets in Asia play a role in the downsizing, the layoffs in Stoke have their roots in earthshaking social shifts. A spokesman for Royal Doulton admitted that the company “has been somewhat slow in catching up with the trend” towar d casual dining. Families eat together less often, he explained, and more people eat alone, either because they are single or they eat in front of television.79.Even dinner parties, if they happen at all, have gone casual. In a time of long work hours and demanding family schedules, busy hosts insist, rightly, that it’s better to share a takeout pizza on paper plates in the family room than to wait for the perfect moment or a “real” dinner party. Too often, the perfect moment never comes. Iron a fine-patterned tablecloth? Forget it. Polish the silver? Who has time?80.Yet the loss of formality has its down side. The fine points etiquette(礼节) that children might once have learned at the table by observation or instruction from parents and grandpa rents. (“Chew with your mouth closed.” “Keep your elbows off the table.”) must be picked up elsewhere. Some companies now offer etiquette seminars for employees who may be competent professionally but clueless socially.Section DDirections: Read the passage carefully and answer the questions or complete the statements in no more than 12 words.A popular saying goes, “Sticks and stones may break my bones, but words will never hurt me.” However, that’s not really true. Words have the power to build us up or tear us down. It doesn’t matter if the words come from someone else or ourselves — the positive and negative effects are just as lasting.We all talk to ourselves sometimes. We’re usually too embarrassed to admit it, though. In fact, we really shouldn’t be because more and more experts believe talking to ourselves out loud is a healthy habit.This “self-talk” helps us motivate ourselves, remember things, solve problems, and calm ourselves down. Be aware, though, that as much as 77% of self-talk tends to be negative. So in order to stay positive, we should only speak words of encouragement to ourselves. We should also be quick to give ourselves a pat on the back. The next time you finish a project, do well in a test, or finally clean your room, join me in s aying “Good job!”Often, words come out of our mouths without us thinking about the effect they will have. But we should be aware that our words cause certain responses in others. For example, when returning an item to a store, we might use warm, friendly language during the exchange. And the clerk will probably respond in a similar manner. Or harsh and critical language will most likely cause the clerk to be defensive.Words possess power because of their lasting effect. Many of us regret something we once said. And we remember unkind words said to us! Before speaking, we should always go through a “ask-yourself” test: Is it true? Is it loving? Is it needed? If what we want to say doesn’t pass this test, then it’s better left unsaid.Words possess power: both positive and negative. Those around us receive encouragement when we speak positively. We can offer hope, build self-esteem and motivate others to do their best. Negative words destroy all those things. Will we use our words to hurt or to heal? The choice is ours.(Note: Answer the questions or complete the statements in NO MORE THAN 10 WORDS.)81. As to the power of words, the author believes they can either ___________________.82. People should only speak words of encouragement to themselves to ___________________.83. What does the underlined part “give ourselves a pat on the back” mean?84. What should we do if the “ask-yourself test” is not passed?第二卷（45分）I.

(9) （用2B 铅笔在答题纸的相应位置连线）② 根据你所连接的导线，应把滑片P 移到 (10) （选填“A”或“B”）端，使滑动变阻器连入电路中的阻值最大，然后闭合电键，再移动滑片直到电压表示数为 (11) 伏时小灯泡正常发光，此时测得的电流表示数如图15所示，则小灯泡的额定功率为 (12) 瓦。
图14ABC图1526．某小组在“研究电流与电压的关系”时，用甲、乙、丙三个导体进行实验，实验中多次改变导体两端的电压大小，并把实验数据分别记录在表一、表二、表三中。
①分析比较实验序号(13) 中的数据可以归纳得出：在电压相同的情况下，通过不同导体的电流不同。
②分析比较实验序号1、2、3的电流与电压变化的倍数关系，导体两端的电压增大几倍通过它的电流也相应增大几倍，初步得出(14) 。
③分析以上三组数据时，发现实验序号(15) 的实验数据存在错误，同学们通过讨论有三种观点：“A 对错误数据进行修改”；“B 针对错误重新实验”；“C 尊重事实不作任何改动”。
你认为(16) 的观点是正确的（选填“A”、“B”或“C”）。
④综合分析导体甲、乙、丙的有效数据，可以发现：同一导体，其两端的电压与通过它的电流的比值相同；不同导体，其两端的电压与通过它的电流的比值不同。
因此，(17) 可以反映出导体的某种性质。
