2010年职称英语综合类A级真题及答案Almost Human?Scientists are racing to build the world’s first thinking robot. This is not science fictio n: some say they will have made it by the year 2020. Carol Packer reports.Machines that walk, speak and feel are no longer science fiction. Kismet is the name of an a ndroid （机器人） which scientists have built at the Massachusetts Institute of Technology （M IT）. Kismet is different from the traditional robot because it can show human emotions. It s eyes, ears and lips move to show when it feels happy, sad or bored. Kismet is one of the f irst of a new generation of androids —— robots that look like human beings —— which can imitate human feelings. Cog, another android invented by the MIT, imitates the action of a mother. However, scientists admit that so far Cog has the mental ability of a two-year-o ld.The optimists （乐观主义） say that by the year 2020 we will have created humanoids （机器人） w ith brains similar to those of an adult human being. These robots will be designed to look l ike people to make them more attractive and easier to sell to the public. What kind of jobs will they do? In the future, robots like Robonaut, a humanoid invented by NASA, will be do ing dangerous jobs, like repairing space stations. They will also be doing more and more of the household work for us. In Japan, scientists are designing androids that will entertai n us by dancing and playing the piano.Some people worry about what the future holds: will robots become monsters （怪物）? Will pe ople themselves become increasingly like robots? Experts predict that more and more people w ill be wearing micro-computers, connected to the Internet, in the future. People will have m icro-chips in various parts of their body, which will connect them to a wide variety of gadg ets （小装置）. Perhaps we should not exaggerate （夸大） the importance of technology, but o ne wonders whether, in years to come, we will still be falling in love, and whether we will still feel pain. Who knows?11 Kismet is different from traditional robots becauseA it thinks for itself.B it is not like science fiction.C it can look after two-year-olds.D it seems to have human feelings.12 What makes Cog special?A It looks like a mother.B It behaves like a child.C It can imitate the behavior of a mother.D It has a huge brain.13 In about 15 years’ time from now, robotsA will become space designers.B will look like monsters.C will behave like animals.D will think like humans.14 In the future robots will alsoA explore space.B entertain people.C move much faster.D do all of the housework.15 What is the writer’s attitude to robots in the future?A Critical.B Hostile.C Objective.D Enthusiastic.参考答案：11.

A set of extraordinary images captured by Japanese scientists mark the first-ever record of a live giant squid （Architeuthis）in the wild.The animal—which measures roughly 25 feet （8 meters）long—was photographed 2，950 feet （900 meters）beneath the North Pacific Ocean. Japanese scientists attracted the squid toward cameras attached to a baited fishing line.The scientists say they snapped more than 500 images of the massive cephalopod before it broke free after snagging itself on a hook. They also recovered one of the giant squid’s two longesttentacles，which severed during its struggle.The photo sequence，taken off Japan‘s Ogasawara Islands in September 2004，shows the squid homing in on the baited line and enveloping it in “a ball of tentacles.”Tsunemi Kubodera of the National Science Museum in Tokyo and Kyoichi Mori of the Ogasawara Whale Watching Association report their observations this week in the journal Proceedings of the Royal Society B.“Architeuthis appears to be a much more active predator than previously suspected，using its elongated feeding tentacles to strike and tangle prey，”the researchers write.They add that the squid was found feeding at depths where no light penetrates even during the day.Giant BreakthroughDespite people’s fascination with this deep-sea behemoth，the giant squid‘s life and habits have remained largely a mystery. The little information known has been mostly based on dead and dying specimens that were caught by commercial fishing boats or washed ashore.The mysterious creature has inspired countless sea monster tales and has been the subject of various scientific expeditions.Since the mid 1990s there have been a number of research trips in search of giant squid. Cameras attached to deep-diving subs or sperm whales have been used to try to capture the elusive animals on film，but without success.The Japanese researchers used sperm whales as guides to help them pinpoint likely giant squid haunts. Over the years whalers have reported finding a high number of large squid beaks in the mammals’stomachs，pegging sperm whales as primary predators of large squid.The images are generating considerable excitement among squid experts.“I think it‘s wonderful that we’ve finally got a picture of a living giant squid，”said Richard Ellis，a research associate at the American Museum of Natural History in New York and author of The Search for the Giant Squid.“I thought it would onl y be a matter of time before someone got images of Architeuthis，”he added.“After all，it‘s not an endangered species，not even all that rare，and it’s one of the largest of all invertebrates. So the Japanese film finaly breaks through and renders the statement ‘nobody has ever seen a living giant squid’inoperative.”Squid expert Martin Collins of the British Antarctic Survey based in Cambridge，England，says the new images are a “fantastic”achievement.The marine biologist says he was skeptical that a dedicated giant squid hunt would succeed. He thought the first wild sighting would probably come by accident.“Fair play to these guys who‘ve made the effort，gone outthere and looked in what they thought was a good area，and found it，”he said.Hunting for CluesCollins is especially interested in clues the images might provide to the way giant squid swim and hunt in the deep ocean.“Seeing the animals on film gives you a tremendous insight into how they live down there，”he said. “It shows they are pretty active animals，and that answers a big question that’s been out there for some time.”Collins says there were two competing schools of thought among giant squid experts.“One was the idea that ［giant squid］were fairly inactive and just drifted around，dangling their tentacles below them like fishing lures to catch what came by，”he said.“The other theory was that they were actually quite active. This new evidence supports this，suggesting they are active predators which can move reasonably quickly.”“The efforts the squi d went to untangle itself ［from the baited fishing line］also shows they are capable of quite strong and rapid movement，”he added.The study team reports that the severed tentacle repeatedly gripped the boat deck and crew after it was hauled aboard. The squ id‘s tentacles are armed with suckers，each ringed with tiny teeth to help snare prey.Measuring 18 feet （5.5 meters）long，analysis of the tentacle confirmed it came from a giant squid and allowed the researchers to estimate the total length of the animal.But the researchers caution that their data assume the tentacle was severed at it base. If not，the squid may have been considerably larger. The longest giant squid on record measured59 feet （18 meters），including its two elongated tentacles.Shedding Light on Giant SquidGiant squid，along with their close cousins colossal squid （Mesonychoteuthis），have the largest eyes of any animal.“Giant squid do have particularly large eyes，which would suggest vision is important to them. Having a large eye isn’t unusual in deep-sea animals-you see it quite often in fish.”The fact that the animal caught on film was swimming in total darkness suggests the species detects prey using alternative light sources. “The only light down there is likely to be light produced by other animals，”said Collins of the British Antarctic Survey.The Japanese team thinks that research techniques similar to their own could be used to bring about more close encounters with giant squid. Ellis of the American Museum of Natural History agrees.“I‘m sure we can learn a lot from an analysis of these images，”he said. “And now that we have an idea of where to look for ［the squid］，we will undoubtedly get more pictures.”1. The passage talks mainly about the studying of a live giant squid by American scientists.2. The giant squid was photographed 2，950 feet beneath the North Pacific Ocean.3. The observations by Tsunemi Kubodera and Kyoichi Mori was reported in the journal Proceedings of Royal Society B.4.

第一部分阅读理解考点2 科普研究类一、(2018年全国卷Ⅰ)DWe may think we're a culture that gets rid of our worn technology at the first sight of something shiny and new，but a new study shows that we keep using our old devices(装置) well after they go out of style．That’s bad new s for the environment — and our wallets — as these outdated devices consume much more energy than the newer ones that do the same things．To figure out how much power these devices are using，Callie Babbitt and her colleagues at the Rochester Institute of Technology in New York tracked the environmental costs for each product throughout its life —from when its minerals are mined to when we stop using the device．This method provided a readout for how home energy use has evolved since the early 1990s．Devices were grouped by generation．Desktop computers，basic mobile phones，and box-set TVs defined 1992．Digital cameras arrived on the scene in 1997．And MP3 players，smart phones，and LCD TVs entered homes in 2002，before tablets and e-readers showed up in 2007．As we accumulated more devices，however，we didn't throw out our old ones．"The living-room television is replaced and gets planted in the kids' room，and suddenly one day，you have a TV in every room of the house，" said one researcher．The average number of electronic devices rose from four per household in 1992 to 13 in 2007．We're not just keeping these old devices — we continue to use them．According to the analysis of Babbitt's team，old desktop monitors and box TVs with cathode ray tubes are the worst devices with their energy consumption and contribution to greenhouse gas emissions（排放）more than doubling during the 1992 to 2007 window．So what's the solution（解决方案）? The team's data only went up to 2007，but the researchers also explored what would happen if consumers replaced old products with new electronics that serve more than one function，such as a tablet for word processing and TV viewing．They found that more on-demand entertainment viewing on tablets instead of TVs and desktop computers could cut energy consumption by 44%．32．What does the author think of new devices?A．They are environment-friendly．B．They are no better than the old．C．They cost more to use at home．D．They go out of style quickly．33．Why did Babbitt's team conduct the research?A．To reduce the cost of minerals．B．To test the life cycle of a product．C．To update consumers on new technology．D．To find out electricity consumption of the devices．34．Which of the following uses the least energy?A．The box-set TV．B．The tablet．C．The LCD TV．D．The desktop computer．35．What does the text suggest people do about old electronic devices?A．Stop using them．B．Take them apart．C．Upgrade them．D．Recycle them．二、(2018年全国卷Ⅱ)BMany of us love July because it’s the month when nature’s berries a nd stone fruits are in abundance．These colourful and sweet jewels form British Columbia’s fields are little powerhouses of nutritional protection．Of the common berries, strawberries are highest in vitamin C, although, because of their seeds, raspberries contain a little more protein (蛋白质), iron and zinc (not that fruits have much protein)．Blueberries are particularly high in antioxidants (抗氧化物质)．The yellow and orange stone fruits such as peaches are high in the carotenoids we turn into vitamin A and which are antioxidants．As for cherries (樱桃), they are so delicious who cares? However, they are rich in vitamin C．When combined with berries of slices of other fruits, frozen bananas make an excellent base for thick, cooling fruit shakes and low fat “ice cream”．For this purpose, select ripe bananas for freezing as they are much sweeter．Remove the skin and place them in plastic bags or containers and freeze．If you like, a squeeze of fresh lemon juice on the bananas will prevent them turning brown．Frozen bananas will last several weeks, depending on their ripeness and the temperature of the freezer．If you have a juicer, you can simply feed in frozen bananas and some berries or sliced fruit．Out comes a “soft-serve” creamy dessert, to be eaten right away．This makes a fun activity for a children’s party；they love feeding the fruit and frozen bananas into the top of the machine and watching the ice cream come out below．24．What does the author seem to like about cherries?A．They contain protein．B．They are high in vitamin A．C．They have a pleasant taste．D．They are rich in antioxidants．25．Why is fresh lemon juice used in freezing bananas?A．To make them smell better．B．To keep their colour．C．To speed up their ripening．D．To improve their nutrition．26．What is “a juicer” in the last paragraph?A．A dessert．B．A drink．C．A container．D．A machine．27．From which is the text probably taken?A．A biology textbook．B．A health magazine．C．A research paper．D．A travel brochure．三、(2018年天津卷)CThere’s a new frontier in 3D printing that’s beginning to come into focus：food．Recent development has made possible machines that print, cook, and serve foods on a mass scale．And the industry isn’t stopping there．Food productionWith a 3D printer, a cook can print complicated chocolate sculptures and beautiful pieces for decoration on a wedding cake．Not everybody can do that — it takes years of experience, but a printer makes it easy．A restaurant in Spain uses a Foodini to “re-create forms and pieces” of food that are “exactly the same,” freeing cooks to complete other tasks．In another restaurant, all of the dishes and desserts it serves are 3D-printed,rather than farm to table．Sustainability(可持续性）The global population is expected to grow to 9．6 billion by 2050, and some analysts estimate that food production will need to be raised by 50 percent to maintain current levels．Sustainability is becoming a necessity．3D food printing could probably contribute to the solution．Some experts believe printers could use hydrocolloids (水解胶体) from plentifulrenewables like algae(藻类) and grass to replace the familiar ingredients(烹饪原料)．3D printing can reduce fuel use and emissions．Grocery stores of the future might stock "food" that lasts years on end, freeing up shelf space and reducing transportation and storage requirements．NutritionFuture 3D food printers could make processed food healthier．Hod Lipson, a professor at Columbia University, said, “Fo od printing could allow consumers to print food with customized nutritional content, like vitamins．So instead of eating a piece of yesterday’s bread from the supermarket, you’d eat something baked just for you on demand．”ChallengesDespite recent advancements in 3D food printing, the industry has many challenges to overcome．Currently, most ingredients must be changed to a paste(糊状物) before a printer can use them, and the printing process is quite time-consuming, because ingredients interact with each other in very complex ways．On top of that, most of the 3D food printers now are restricted to dry ingredients, because meat and milk products may easily go bad．Some experts are skeptical about 3D food printers, believing they are better suited for fast food restaurants than homes and high-end restaurants．46．What benefit does 3D printing bring to food production?A．It helps cooks to create new dishes．B．It saves time and effort in cooking．C．It improves the cooking conditions．D．It contributes to restaurant decorations．47．What can we learn about 3D food printing from Paragraphs 3?A．It solves food shortages easily．B．It quickens the transportation of food．C．It needs no space for the storage of food．D．It uses renewable materials as sources of food．48．According to Paragraph 4, 3D-printed food ________．A．is more available to consumersB．can meet individual nutritional needsC．is more tasty than food in supermarketsD．can keep all the nutrition in raw materials49．What is the main factor that prevents 3D food printing from spreading widely?A．The printing process is complicated．B．3D food printers are too expensive．C．Food materials have to be dry．D．Some experts doubt 3D food printing．50．What could be the best title of the passage?A．3D Food Printing：Delicious New TechnologyB．A New Way to Improve 3D Food PrintingC．The Challenges for 3D Food ProductionD．3D Food Printing：From Farm to Table四、(2018年江苏卷)BIn the 1760s, Mathurin Roze opened a series of shops that boasted（享有）a special meat soup called consommé．Although the main attraction was the soup, Roze’s chain sh ops also set a new standard for dining out, which helped to establish Roze as the inventor of the modern restaurant．Today,scholars have generated large amounts of instructive research about restaurants．Take visual hints that influence what we eat：diners served themselves about 20 percent more pasta（意大利面食）when their plates matched their food．When a dark-colored cake was served on a black plate rather than a white one, customers recognized it as sweeter and more tasty．Lighting matters, too．When Berlin restaurant customers ate in darkness, they couldn’t tell how much they’d had：those given extra-large shares ate more than everyone else, but were none the wiser—they didn’t feel fuller, and they were just as ready for dessert．Time is money，but that principle means different things for different types of restaurants．Unlike fast-food places, fine dining shops prefer customers to stay longer and spend．One way to encourage customers to stay and order that extra round：put on some Mozart(莫扎特）．When classical, rather than pop, music was playing, diners spent more．Fast music hurried diners out．Particular scents also have an effect：diners who got the scent of lavender（薰衣草）stayed longer and spent more than those who smelled lemon, or no scent．Meanwhile, things that you might expect to discourage spending—＂bad＂tables, crowding, high prices —don’t necessarily．Diners at bad tables —next to the kitchen door, say —spentnearly as much as others but soon fled．It can be concluded that restaurant keepers need not ＂be overly co ncerned about ‘bad’ tables,＂given that they’re profitable．As for crowds, a Hong Kong study found that they increased a restaurant’s reputation, suggesting great food at fair prices．And doubling a buffet’s price led customers to say that its pizza was 11 p ercent tastier．58．The underlined phrase ＂none the wiser＂in paragraph 3 most probably implies that the customers were ．A．not aware of eating more than usual B．not willing to share food with othersC．not conscious of the food quality D．not fond of the food provided59．How could a fine dining shop make more profit?A．Playing classical music．B．Introducing lemon scent．C．Making the light brighter．D．Using plates of larger size．60．What does the last paragraph talk about?A．Tips to attract more customers．B．Problems restaurants are faced with．C．Ways to improve restaurants’ reputation．D．Common misunderstandings about restaurants．五、(2018年北京卷)DPreparing Cities for Robot CarsThe possibility of self-driving robot cars has often seemed like a futurist’s dream，years away from materializing in the real world．Well，the future is apparently now．The California Department of Motor Vehicles began giving permits in April for companies to test truly self-driving cars on public roads．The state also cleared the way for companies to sell or rent out self-driving cars，and for companies to operate driverless taxi services．California，it should be noted，isn’t leading the way here．Companies have been testing their vehicles in cities across the country．It’s hard to predict when driverless cars will be everywhere on our roads．But however long it takes，the technology has the potential to change our transportation systems and our cities，for better or for worse，depending on how the transformation is regulated．While much of the debate so far has been focused on the safety of driverless cars(and rightfully so)，policymakers also should be talking about how self-driving vehicles can help reduce traffic jams，cut emissions(排放) and offer more convenient，affordable mobilityoptions．The arrival of driverless vehicles is a chance to make sure that those vehicles are environmentally friendly and more shared．Do we want to copy — or even worsen — the traffic of today with driverless cars? Imagine a future where most adults own individual self-driving vehicles．They tolerate long，slow journeys to and from work on packed highways because they can work，entertain themselves or sleep on the ride，which encourages urban spread．They take their driverless car to an appointment and set the empty vehicle to circle the building to avoid paying for parking．Instead of walking a few blocks to pick up a child or the dry cleaning，they send the self-driving minibus．The convenience even leads fewer people to take public transport —an unwelcome side effect researchers have already found in ride-hailing(叫车) services．A study from the University of California at Davis suggested that replacing petrol-powered private cars worldwide with electric，self-driving and shared systems could reduce carbon emissions from transportation 80% and cut the cost of transportation infrastructure(基础设施) and operations 40% by 2050．Fewer emissions and cheaper travel sound pretty appealing．The first commercially available driverless cars will almost certainly be fielded by ride-hailing services，considering the cost of self-driving technology as well as liability and maintenance issues(责任与维护问题)．But driverless car ownership could increase as the prices drop and more people become comfortable with the technology．Policymakers should start thinking now about how to make sure the appearance of driverless vehicles doesn’t extend the worst aspects of the car-controlled transportation system we have today．The coming technological advancement presents a chance for cities and states to develop transportation systems designed to move more people，and more affordably．The car of the future is coming．We just have to plan for it．47．According to the author，attention should be paid to how driverless cars can _____．A．help deal with transportation-related problemsB．provide better services to customersC．cause damage to our environmentD．make some people lose jobs48．As for driverless cars，what is the author’s major concern?A．Safety．B．Side effects．C ．Affordability ．D ．Management ．49．What does the underlined word ＂fielded ＂ in Paragraph 4 probably mean?A ．Employed ．B ．Replaced ．C ．Shared ．D ．Reduced ．50．What is the author’s attitude to the future of self -driving cars?A ．Doubtful ．B ．Positive ．C ．Disapproving ．D ．Sympathetic ． 六、（2017年新课标卷Ⅰ）A build-it-yourself solar still （蒸馏器） is one of the best ways to obtain drinking water in areas where the liquid is not readily available ．Developed by two doctors in the U ．S ．Department of Agriculture, it ’s an excellent water collector ．Unfortunately, you must carry the necessary equipment with you, since it ’s all but impossible to find natural substitutes ． The only components required, though, are a 55''⨯ sheet of clear or slightly milky plastic, six feet of plastic tube, and a container — perhaps just a drinking cup — to catch the water ．These pieces can be folded into a neat little pack and fastened on your belt ．To construct a working still, use a sharp stick or rock to dig a hole four feet across and three feet deep ．Try to make the hole in a damp area to increase the water catcher ’s productivity ．Place your cup in the deepest part of the hole ．Then lay the tube in place so that one end rests all the way in the cup and the rest of the line runs up — and out — the side of the hole ．Next, cover the hole with the plastic sheet, securing the edges of the plastic with dirt and weighting the sheet ’s center down with a rock ． The plastic should now form a cone(圆锥体) with 45-degree-angled sides ． The low point of the sheet must be centered directly over, and no more than three inches above, the cup ．The solar still works by creating a greenhouse under the plastic ．Ground water evaporates (蒸发) and collects on the sheet until small drops of water form, run down the material and fall off into the cup ． When the container is full, you can suck the refreshment out through the tube, and won ’t have to break down the still every time you need a drink ．32．What do we know about the solar still equipment from the first paragraph?A ．It’s delicate ．B ．It’s expensive ．C ．It’s complex ．D ．It’s portable ．33．What does the underlined phrase “the water catcher” in paragraph 2 refer to?A．The tube．B．The still．C．The hole．D．The cup．34．What’s the last step of constructing a working solar still?A．Dig a hole of a certain size．B．Put the cup in place．C．Weight the sheet’s center down．D．Cover the hole with the plastic sheet．35．When a solar still works, drops of water come into the cup form ．A．the plastic tube B．outside the holeC．the open air D．beneath the sheet七、（2017年新课标卷Ⅱ）When a leafy plant is under attack，it doesn’t sit quietly．Back in 1983，two scientists，Jack Schultz and Ian Baldwin，reported that young maple trees getting bitten by insects send out a particular smell that neighboring plants can get．These chemicals come from the injured parts of the plant and seem to be an alarm．What the plants pump through the air is a mixture of chemicals known as volatile organic compounds，VOCs for short．Scientists have found that all kinds of plants give out VOCs when being attacked．It’s a plant’s way of crying out．But is anyone listening? Apparently．Because we can watch the neighbors react．Some plants pump out smelly chemicals to keep insects away．But others do double duty．They pump out perfumes designed to attract different insects who are natural enemies to the attackers．Once they arrive，the tables are turned．The attacker who was lunching now becomes lunch．In study after study，it appears that these chemical conversations help the neighbors．The damage is usually more serious on the first plant，but the neighbors，relatively speaking，stay safer because they heard the alarm and knew what to do．Does this mean th at plants talk to each other? Scientists don’t know．Maybe the first plant just made a cry of pain or was sending a message to its own branches，and so，in effect，was talking to itself．Perhaps the neighbors just happened to “overhear” the cry．So information was exchanged，but it wasn’t a true，intentional back and forth．Charles Darwin，over 150 years ago，imagined a world far busier，noisier and more intimate(亲密的) than the world we can see and hear．Our senses are weak．There’s a whole lot going on．32．What does a plant do when it is under attack?A．It makes noises．B．It gets help from other plants．C．It stands quietly D．It sends out certain chemicals．33．What does the author mean by “the tables are turned” in paragraph 3?A．The attackers get attacked．B．The insects gather under the table．C．The plants get ready to fight back．D．The perfumes attract natural enemies．34．Scientists find from their studies that plants can ．A．predict natural disasters B．protect themselves against insectsC．talk to one another intentionally D．help their neighbors when necessary 35．what can we infer from the last paragraph?A．The word is changing faster than ever．B．People have stronger senses than beforeC．The world is more complex than it seemsD．People in Darwin’s time were more imaginative．八、（2017年新课标卷Ⅲ）The Intelligent Transport team at Newcastle University have turned an electric car into a mobile laboratory named “DriveLAB” in order to understand the challenges faced by older drivers and to discover where the key stress points are．Research shows that giving up driving is one of the key reasons for a fall in health and well-being among older people, leading to them becoming more isolated(隔绝) and inactive．Led by Professor Phil Blythe, the Newcastle team are developing in-vehicle technologies for older drivers which they hope could help them to continue driving into later life．These include custom-made navigation(导航) tools, night vision systems and intelligent speed adaptations．Phil Blythe explains：“For many older people, particularly those living alone or in the country, driving is important for preserving their independence, giving them the freedom to get out and about without having to rely on others．”“But we all have to accept that as we get older our reactions slow down and this often results in people avoiding any potentially challenging driving conditions and losing confidence in theirdriving skills．The result is that people stop driving before they really need to．”Dr Amy Guo，the leading researcher on the older driver study, explains, “The DriveLAB is helping us to understand what the key points and difficulties are for older drivers and how we might use technology to address these problems．“For example, most of us would expect older drivers always go slower than everyone else but surprisingly, we found that in 30mph zones they struggled to keep at a constant speed and so were more likely to break the speed limit and be at risk of getting fined．We’re looking at the benefits of systems which control their speed as a way of preventing that．“We hope that our work will help with technological solutions(解决方案) to ensure that older drivers stay safer behind the wheel．”32．What is the purpose of the Drivel AB?A．To explore new means of transport．B．To design new types of cars．C．To find out older driver`s problems．D．To teach people traffic rules．33．Why is driving important for older people according to Phil Blythe?A．It keeps them independent．B．It helps them save time．C．It builds up their strength．D．It cures their mental illnesses．34．What do researchers hope to do for older drivers?A．Improve their driving skills．B．Develop driver-assist technologies．C．Provide tips on repairing their cars．D．Organize regular physical checkups．35．What is the best title for the text?A．A new Model Electric CarB．A Solution to Traffic ProblemC．Driving Service for eldersD．Keeping Older Drivers on the Road九、（2017年北京卷）Hollywood’s theory that machines with evil(邪恶) minds will drive armies of killer robots is just silly．The real problem relates to the possibility that artificial intelligence(AI) may become extremely good at achieving something other than what we really want．In 1960 a well-known mathematician Norbert Wiener，who founded the field of cybernetics（控制论），put it this way：“If we use，to achieve our purposes，a mechanical agency with whose operation we cannot effectively interfere(干预)，we had better be quite sure that the purpose put into the machine is the purpose which we really desire．”A machine with a specific purpose has another quality，one that we usually associate with living things：a wish to preserve its own existence．For the machine，this quality is not in-born，nor is it something introduced by humans; it is a logical consequence of the simple fact that the machine cannot achieve its original purpose if it is dead．So if we send out a robot with the single instruction of fetching coffee，it will have a strong desire to secure success by disabling its own off switch or even killing anyone who might interfere with its task．If we are not careful，then，we could face a kind of global chess match against very determined，super intelligent machines whose objectives conflict with our own，with the real world as the chessboard．The possibility of entering into and losing such a match should concentrate the minds of computer scientists．Some researchers argue that we can seal the machines inside a kind of firewall，using them to answer difficult questions but never allowing them to affect the real world．Unfortunately，that plan seems unlikely to work：we have yet to invent a firewall that is secure against ordinary humans，let alone super intelligent machines．Solving the safety problem well enough to move forward in AI seems to be possible but not easy．There are probably decades in which to plan for the arrival of super intelligent machines．But the problem should not be dismissed out of hand，as it has been by some AI researchers．Some argue that humans and machines can coexist as long as they work in teams—yet that is not possible unless machines share the goals of humans．Others say we can just “switch them off” as if super intelligent machines are too stupid to think of that possibility．Still others think that super intelligent AI will never happen．On September 11，1933，famous physicist Ernest Rutherford stated，with confidence，“Anyone who expects a source of power in the transformation of these atoms is talking moonshine．” However，on September 12，1933，physicist Leo Szilard inventedthe neutron-induced(中子诱导) nuclear chain reaction．67．Paragraph 1 mainly tells us that artificial intelligence may ．A．run out of human controlB．satisfy human’s real desiresC．command armies of killer robotsD．work faster than a mathematician68．Machines with specific purposes are associated with living things partly because they might be able to ．A．prevent themselves from being destroyedB．achieve their original goals independentlyC．do anything successfully with given ordersD．beat humans in international chess matches69．According to some researchers，we can use firewalls to ．A．help super intelligent machines work betterB．be secure against evil human beingsC．keep machines from being harmedD．avoid robots’ affecting the worl d70．What does the author think of the safety problem of super intelligent machines?A．It will disappear with the development of AI．B．It will get worse with human interference．C．It will be solved but with difficulty．D．It will stay for a decade．十、（2017年浙江卷）Getting less sleep has become a bad habit for most American kids．According to a new survey(调查) by the National Sleep Foundation，51% of kids aged 10 to 18 go to bed at 10 pm or later on school nights，even though they have to get up early．Last year the Foundation reported that nearly 60% of 7- to 12-year-olds said they felt tired during the day，and 15% said they had fallen asleep at school．How much sleep you need depends a lot on your age．Babies need a lot of rest: most of them sleep about 18 hours a day! Adults need about eight hours．For most school-age children，tenhours is ideal(理想的)．But the new National Sleep Foundation survey found that 35% of 10- to 12-year-olds get only seven or eight hours．And guess what almost half of the surveyed kids said they do before bedtime? Watch TV．“More children are going to bed with TVs on，and there are more opportunities(机会) to stay awake，with more homework，the Internet and the phone，” says Dr．Mary Carskadon，a sleep researcher at Brown University Medical School．She says these activities at bedtime can get kids all excited and make it hard for them to calm down and sleep．Other experts say part of the problem is chemical．Changing levels of body chemicals called hormones not only make teenagers’ bodies develop adult characteristics，but also make it hard for teenagers to fall asleep before 11 pm．Because sleepiness is such a problem for teenagers，some school districts have decided to start high school classes later than they used to．Three years ago，schools in Edina，Minnesota，changed the start time from 7:25 am to 8:30 am．Students，parents and teachers are pleased with the results．25．What is the new National Sleep Foundation survey on?A．American kids’ sleeping habits．B．Teenagers’ sleep-related diseases．C．Activities to prevent sleeplessness．D．Learning problems and lack of sleep．26．How many hours of sleep do 11-year-olds need every day?A．7 hours．B．8 hours．C．10 hours．D．18 hours．27．Why do teenagers go to sleep late according to Carskadon?A．They are affected by certain body chemicals．B．They tend to do things that excite them．C．They follow their parents’ examples．D．They don’t need to go to school early．十一、（2017年江苏卷）Population ChangeWhy is the world’s population growing? The answer is not what you might think．The reason for the explosion is not that people have been reproducing like rabbits，but that people have stopped dropping dead like flies．In 1900，people died at the average age of 30．By 2000 the average age was 65．But while increasing health was a typical feature of the 20th century，。
