If you could be anybody in the world, who would it be? Your neighbour or a super star? A few people have experienced what it might be like to step into the skin of another person, thanks to an unusual virtual reality(虚拟现实)device. Rikke Wahl, an actress, model and artist, was one of the participants in a body swapping experiment at the Be Another lab, a project developed by a group of artists based in Barcelona. She swapped with her partner, an actor, using a machine called The Machine to Be Another and temporarily became a man. "As I looked down, I saw my whole body as a man, dressed in my partner's pants," she said. "That's the picture I remember best."The set-up is relatively simple. Both users wear a virtual reality headset with a camera on the top. The video from each camera is sent to the other person, so what you see is the exact view of your partner. If she moves her arm, you see it. If you move your arm, she sees it.To get used to seeing another person's body without actually having control of it, participants start by raising their arms and legs very slowly, so that the other can follow along. Eventually, this kind of slow synchronised(同步的)movement becomes comfortable, and participants really start to feel as though they are living in another person's body.Using such technology promises to alter people's behaviour afterwards-potentially for the better. Studies have shown that virtual reality can be effective in fighting racism-the bias(偏见)that humans have against those who don't look or sound like them. Researchers at the University of Barcelona gave people a questionnaire called the Implicit Association Test, which measures the strength of people's associations between, for instance, black people and adjectives such as good, bad, athletic or awkward. Then they asked them to control the body of a dark skinned digital character using virtual reality glasses, before taking the test again. This time, the participants' bias scores were lower. The idea is that once you've "put yourself in another's shoes" you're less likely to think ill of them, because your brain has internalised the feeling of being that person.The creators of The Machine to Be Another hope to achieve a similar result. "At the end of body swapping, people feel like holding each other in their arms," says Arthur Pointeau, a programmer with the project. "It's a really nice way to have this kind of experience. I would really, really recommend it to everyone."74. The word "swapping" (paragraph 1) is closest in meaning to______.A. buildingB. exchangingC. controllingD. transplanting75. We can infer from the experiment at the Be Another lab that______.A. our feelings are related to our bodily experienceB. we can learn to take control of other people's bodiesC. participants will live more passionately after the experimentD. The Machine to Be Another can help people change their sexes76. In the Implicit Association Test, before the participants used virtual reality glasses to control a dark skinned digital character,______.A. they fought strongly against racismB. they scored lower on the test for racismC. they changed their behaviour dramaticallyD. they were more biased against those unlike them77. It can be concluded from the passage that______.A. technology helps people realize their dreamsB. our biases could be eliminated through experimentsC. virtual reality helps promote understanding among peopleD. our points of view about others need changing constantly74.B 75.A 76.D 77.C二、模块精讲1.virtual adj.实质上的,实际的,事实上的【拓展】virtually adv.实质上,实际上The President was so much under the influence of his wife that she was the virtual ruler of the country.总统受到他妻子很大的影响,她才是这个国家真正的统治者。

II. Grammar and VocabularySection ADirections: After reading the passage below, fill in the blanks to make the passages coherent and grammatically correct. For the blanks with a given word, fill in each blank with the proper form of the given word; for the other blanks, use one word that best fits each blank.Developing Competent TeachingNations that have greatly improved their students’achievements, such as Finland, Korea, Singapore, and others, attribute much of their success to their focused investments in teacher preparation and development. 21 (Create) a system that can routinely hire and prepare teachers effectively and can support successful teaching is the arena (竞技场) in which the United States 22 (fall) behind the most. Although there are some great teachers in every community, the landscape of the supports for quality teaching looks like Swiss cheese. In some states, the holes are smaller, and in others they are bigger. Nor in no case is there a fully 23 (develop) system of instructional support even remotely comparable to that in high-achieving nations. And of course, as we have seen, the system is the weakest in communities 24 students’ needs are greatest.Some have argued that the answer to weak teaching in the United States id to eliminate “barriers” to teaching, such as teacher education and certification requirements, allow anyone who wants to teach into the classroom, and fire those who prove not to be effective. Although the interest in teaching effectiveness is important, this approach does not offer strategy 25 (ensure) that teachers will have opportunities to gain the knowledge and skills they need in order to be effective, or that all schools will have the resources to attract and hire the best teachers.26 does it protect the students in low-income schools, who will be the victims of unprepared and inexperienced teachers in the years until these teachers have demonstrated their incapability and left the field.A regulation 27 (focus) on easy access and easy firing ignores the question of how to develop widespread teaching skills and ensure a strong supply of highly able teachers for schools. 28 such supply, principals will be unable to hire strong teachers even if they are free to hire whomever they are pleased with, and, evidence shows that schools are likely to fire weak teachers, 29 they feel they won’t be able to replace them. Even if they do, thereis little guarantee that the quality of teaching 30 (improve). although there are good reasons to argue for stringer evaluation practices for removing incapable teachers and for recognizing excellent ones, a theory that the major problems with teaching can be solved by carrots and sticks alone leaves the development of teaching abilities to chance.Section BDirections: Complete the following passage by using the words in the box. Each word can only be used once. Note that there is one word more than you need.What is leadership?Its qualities are difficult to define,but they are not so difficult to identify.

Sometimes these interactions pass by virtually___41___ , like when you find yourself forced to by the newest cell phone but suddenly stop and ask yourself, “ D o I even need this thing?” and then realize that the latest ad campaign has ____42____you of something without you really knowing it. Sometimes these interactions with others are obvious and deeply felt, like when an emotional argument____43____over why your father won’t quit smoking even though his health is____44____ ---you only see your desire for him to be OK, he only sees his independence. then there are those times when those sorts of____45____ feel delighted---like when you voice your opinion, as you do every year at the thanksgiving table, about some political issues, and finally---after years of trying---see the ____46____of “hmm, you may be right’ on your uncle’s face.Advertising, media, novels and even the people you love often aim to____47____your opinion.

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 read.( A )Companies Take Punitive Steps Against Smoker ,Overweight WorkersBy Tim JonesGet ready to say goodbye to the days of high-fat meals,junk food and that after-work cigarette you always enjoy smoking at-least if you intend to have a job and health insurance.The rule of the workplace are changing and personal behavior and lifestyle habits -those unrelated to what you do at work are -now fair game for employers determined to cut health-care costs.If you smoke ,you may not get hired and you could get fired,If you cholesterol is too high,you can pay higher premiums for you insurance .The same goes for blood pressure and body mass.The requirement accepted by a growing number of companies are encroaching on privacy and raising questions about who will qualify for health insurance ,as well as employment.The Cleveland Clinic on Sept.I started nicotine testing in pre-employment physicals .If nicotine is found ,applicants will not be hired.We -yco Inc,a company based in Lansing,Michigan,drew national attention in 2005 when it fired four employees who used tobacco .We-yco performs random testing every 3 months ,usually of about 30 employees .Workers are required to blow into a Breathalyzer-link device that measures carbon monoxide levels .If the reading is high ,employees are required to take a urine test.If they fail the urinalysis twice ,they will be dismissed.Although thousands of employees have put in place inspiration for their workers to live healthier lifestyles,the vast majority of employers have not yet adopted the approach of punishing employees who do not satisfy medical or behavioral requirements.But punitive measures are gaining a foothold in the workplace,according to lawyer and groups that follow insurance and employment trends, because health-care costs are double-digit rates annually.Gray Climes ,vice president of Meritain Health Michigan ,which now owns We-yco, noted that firings did not violate Michigan law and that 150 employees at the Okemos-based company have ,over time ,accepted the rules . It really comes down to a personal choice as far as you want to be employ ed here.”Climes said .Climes said that since 2005,when we-yco made the wellness policy that includes that the smoking ban ,health insurance costs have increased by 2 percent a year,well below the national average.56.What is the author’s advice on getting employed?A.Paying high er premiums of health insurance.B.Quitting smoking and keeping away from junk foodC.Taking a urine test before applying for a good job.D.Studying hard and knowing more about the company.57.The italicized words encroaching on in the passage mean---A.enrichingB.recoveringC.protectingD.invading58.We-yco Ine,drew national attention in 2005 because ----A.four of its employees were fired just for smokingB.four of its employees violated Michigan lawC.Its health insurance costs have increased rapidlyD. A device was used to measure carbon monoxide levels59.What is the most probable title of this passage ?A .Health insurance costs are increasingB.urine tests are required for every employeeC.most of the employer get tough on healthD.employees are provided with good health care( B )Portuguese and Spanish explorers made the first European voyage into unknown waters. Curiosity, religion and economic goals drove these courageous men forward. Their voyages resulted in great advances for the sponsoring governments and served as the foundation for future empires.One man largely responsible for Portugal’s interest in exploration was a member of the Portuguese royal family named Prince Henry. Also known as “The Navigator”, Prince Henry’s primary goal was to find gold for Portugal. The Portuguese also hoped to find a way to the rich spice trade of the Indies and to spread the Christian faith.Henry gathered many Europe’s best geographers and navigators to plan expeditions. By about 1420 or earlier, his navigators were exploring westward into the Atlantic , and by the 1430s,they were moving southward along the west coast of Africa . Henry’s explorers claimed the Azores for Portugal . In Africa, they began to trade for slaves , gold and ivory .The success of these early voyages of discovery and exploration created great excitement throughout Europe. Success encouraged more voyages . In 1488, Baritolomeu Dias sailed around the Cape of Good Hope at the southern tip of Africa . Although Dias had to turn back , he had found the route to the Indian Ocean .Using this knowledge , Vasco da Gama sailed eastward across the Indian Ocean . He landed in India in 1498 . Several years later , da Gama made a second voyage to India . He returned to Portugal , his ships full of valuable goods .Thanks to Dias and da Gama , an overseas trade route from Europe to India and the East Indies was now available . Rich cargoes of spices and jewels arrived in Portugal . This direct ocean route saved the Portuguese from having to deal with middlemen traders . Now , the Portuguese could journey directly to the sources of the trade goods they sought . In many cases ,ships could carry goods more cheaply than could overland caravans(大篷车) . Nor could Portuguese merchants be blocked or charged high fees by competing powers that controlled overland routes . Overseas trade promised wealth for merchants and sailors and goods for Europe’s markets.60.The main purpose of Henry’s voyage was to ____________.A.explore the unknown waters beyond EuropeB.find gold for the royal familyC.seek for a route to the Indian OceanD.expand Portuguese trade to Africa61.Who was the first to find the route to the Indian Ocean?A.Prince Henry .B.Vasco da Gama.C.Baritolomeu Dias.D.Portuguese merchants.62.It can be inferred from the passage that ___________.A.Merchants used to be charged high fees by middlemen traders.B.Prince Henry blocked Portuguese merchants along overland routes.C.Dias and da Gama were the pioneers to reach the Cape of Good Hope.D.The overseas trade route from Europe to India benefited Portugal a lot .( C )Many United States companies have made the search for legal protection from import competition into a major line of work. Since 1980, the United States International Trade Commission (ITC) has received about 280 complaints alleging damage from imports that benefit from subsidies(补贴) by foreign governments. Another 340 charge that foreign companies “dumped” their products in the United States at “less than fair value.” Even when no unfair practices are claimed, the simple claim that an industry has been injured by imports is sufficient grounds to seek relief(救济).Contrary to the general impression, this request for import relief has hurt more companies than it has helped. As corporations begin to function globally, they develop a complicated web of marketing, production, and research relationships. The complexity of these relationships makes it unlikely that a system of import relief laws will meet the strategic needs of all the units under the same parent company. Internationalization increases the danger that foreign companies will use import relief laws against the very companies the laws were designed to protect. Suppose a United States-owned company establishes an overseas plant to manufacture a product while its competitor makes the same product in the United States. If the competitor can prove injury from the imports—and that the United States company received a subsidy from a foreign government to build its plant abroad—the United States company’s products will be uncompetitive in the United States, since they would be subject to duties.Perhaps the most shameful case occurred when the ITC investigated allegations(控诉) that Canadian companies were injuring the United States salt industry b y dumping rock salt, used to de ice roads. The bizarre aspect of the complaint was that a foreign conglomerate(联合企业)with United States operations was crying for help against a United States company with foreign operations. The “United States” company claiming injury was a unit of a Dutch conglomerate, while the “Canadian” companies included a unit of a Chicago firm that was the second-largest domestic producer of rock salt.63.The passage is chiefly concerned with_______________A.arguing against the increased internationalization of US corporationsB.warning that the application of laws affecting trade frequently has unintended consequencesC.recommending a uniform method for handling claims of unfair trade practicesD.advocating the use of trade restrictions for "dumped" products but not for other imports.64.What can be inferred about the minimal basis for a complaint to the ITC ____________.A. A foreign competitor is selling products in the US at less than fair market value.B. A foreign competitor has greatly increased the volume of products shipped to the US.C. The company requesting import relief has been banned from exporting products.D. The company requesting import relief has been injured by the sale of imports in the US.65.What is the function of the last paragraph?A. It summarizes the discussion and suggests additional areas for research.B. It makes a recommendation based on the evidence presented earlier.C. It uses a specific case to illustrate a problem in the previous paragraph.D. It introduces an additional area of concern not mentioned earlier.66.Which of the following is most likely to be true of US trade laws?A. They will eliminate the practice of "dumping" products in the US.B. Those applied to international companies will help to gain more profits.C. They will affect US trade with Canada more negatively than trade with other nations.D. Those helping one unit within a parent company won’t necessarily help other units.Section CDirections: Read the following passage. Fill in each blank with a proper sentence given in the box. Each sentence can be used only once. Note that there are two more sentences than you need.As people recognize the dangers of fossil fuel plants, especially the risk of global warming from carbon dioxide production—nuclear power begins to look more attractive. But what about the waste—all that highly radioactive debris(残核) that will endure for thousands of years? Nuclear waste is one of the biggest technical issues that any future president is likely toface.______67________Plutonium(钚) has a half-life of 24,000 years. Even after 100,000 years, the radiation will still be above 10% of the level it had when it left thereactor.______68_________How can we possibly prove that this material can be kept safe for 100000 years?Still the US government persists in p ursuing “safe”nuclear waste disposal(处理). It has created nuclear waste facilities buried deep within Yucca Mountain , Nevada. To keep the waste safe, the storage rooms are 1,000feet below the surface. _______69__________. It needs at least 2 square miles. The cost of the facility is expected to reach $100 billion ,with hundreds of billions of dollars more in operating costs. To make matters worse, earthquakes happen often in the Yucca Mountain region. More than 600 earthquakes of magnitude of 2.5 and higher have occurred within 50 miles in the last decade alone. Although that was millions of years ago, how sure can we be that the waste facility won’t be torn apart by another eruption?________70_________ Why not just send the waste into the sun? Well, maybe that’s not such a good idea, since on launch some rockets do crash back down to the earth. Some scientists have proposed that the waste be put in ships and sunk under the oceans. Yet just the fact that scientists make such suggestions seems to emphasize how the problem really is.IV. Summary WritingDirections: Read the following passage. Summarize the main idea and the main point(s) of the passage in no more than 60 words. Use your own words as far as possible.To airline and airport operators, fog is an enemy. When the white, misty blanket hides runways, airplanes cannot take off or land. Changes in flight schedules cost the airlines several million dollars each year.Fog is an concentration of tiny water droplets suspended in the air. It most often occurs when warm, most air is suddenly cooled. To clear the air of fog, it is necessary to evaporate the droplets or cause them to join together and fall as rain or snow.In 1968, a new fog-sweeping machine was tested for dissipating(驱散)the most common king of fog, which occurs at temperature above freezing. The machine consists of 100-foot-long plastic tube mounted on a mobile blower. As the machine moved across the airport, chemicals were blown through the tube and up into the fog. One of the chemicals reduces the surface tension on the water droplets so that they would join together more easily. Another chemical gave an electronic charge to the droplets, so that they attracted each other and fell as rain.Cold fog, which occurs at temperatures below freezing, causes only a small percentage of airport shutdowns. Cold fog is fairly easy to eliminate. For quite a few years, airports have used cloud-seeding methods to dissipate cold fog. An airplane drops crystals of dry ice into the fog. Soon, snow falls and the air clears.In the 1900s, another kind of weapon against fog was developed. Pilots who are flying through fog fire a pulse of laser light toward the runway. The light that would normally be reflected by the fog is screened out by a sensor. When the laser pulse returns, the sensor opens briefly to admit only the light reflected from the runway, thus enabling the laser to “see” the runway through the fog.These new “whether weapons” are helping to win the war against fog.第II卷(共40分)V.
