Text 2 Since the dawn of human ingenuity, people have devised ever more cunning tools to cope with work that is dangerous, boring, burdensome, or just plain nasty. That compulsion has resulted in robotics--the science of conferring various human capabilities on machines. And if scientists have yet to create the mechanical version of science fiction, they have begun to come close.As a result, the modern world is increasingly populated by intelligent gizmos whose presence we barely notice but whose universal existence has removed much human labor. Our factories hum to the rhythm of robot assembly arms. Our banking is done at automated teller terminals that thank us with mechanical politeness for the transaction. Our subway trains are controlled by tireless robo-drivers. And thanks to the continual miniaturization of electronics and micro-mechanics, there are already robot systems that can perform. some kinds of brain and bone surgery with submillimeter accuracy--far greater precision than highly skilled physicians can achieve with their hands alone.But if robots are to reach the next stage of laborsaving utility, they will have to operate with less human supervision and be able to make at least a few decisions for themselves--goals that pose a real challenge. "While we know how to tell a robot to handle a specific error," says Dave Lavery, manager of a robotics program at NASA, "we can't yet give a robot enough 'common sense' to reliably interact with a dynamic world. "Indeed the quest for true artificial intelligence has produced very mixed results. Despite a spell of initial optimism in the 1960s and 1970s when it appeared that transistor circuits and microprocessors might be able to copy the action of the human brain by the year 2010, researchers lately have begun to extend that forecast by decades if not centuries.What they found, in attempting to model thought, is that the human brain's roughly one hundred billion nerve cells are much more talented-and human perception far more complicated--than previously imagined. They have built robots that can recognize the error of a machine panel by a fraction of a millimeter in a controlled factory environment. But the human mind can glimpse a rapidly changing scene and immediately disregard the 98 percent that is irrelevant, instantaneously focusing on the monkey at the side of a winding forest road or the single suspicious face in a big crowd. The most advanced computer systems on Earth can't approach that kind of ability, and neuroscientists still don't know quite how we do it.第46题：Human ingenuity was initially demonstrated inA the use of machines to produce science fiction.B the wide use of machines in manufacturing industry.C the invention of tools for difficult and dangerous work.D the elite's cunning tackling of dangerous and boring work.

共用题干PainAll of us have felt pain.We have cut ourselves.We have been burned.Or we have had headaches.Some of us suffer pain rarely. ________(46)Pain can take complete control of our body and mind,making it impossible to move and even to think. Yet we need pain.Without it,we would not know if we have hurt ourselves.It is our body's warning sys-tem.________（47)Pain is the most common reason we go to a doctor. It is the most common reason we take medicines. Until recently,however,most doctors knew of only a few drugs that stopped some pains.________(48) But new knowledge about the process of pain is helping them to control pain better.Scientists have learned that the sense of pain is made up of both chemical and electrical signals. ________(49)Scientists also have learned that the nervous system sends two different kinds of pain messages to the brain:one very fast,the other slow. The first message is the warning signal.It moves at a speed of 30 meters a second.In less than a second,the brain understands that part of the body is hurt and how badly it is injured.________(50)It tells us not to use the injured part until it heals.____________(47)A:And others have painful attacks all the time.B: These signals travel from nerve cells in the injured area,up the spinal cord（脊髓）to the brain,and back down again.C:It tells us that we are injured and should do something about it.D:They knew little about the process of pain itself.E:The other message moves at a speed of only one meter a second.F: And they send the second,slower message of pain to the brain.
共用题干第三篇 Smart ExerciseDoctors are starting to find more and more information that suggests a connection between exercise and brain development.Judy Cameron,a scientist at Oregon Health and Science University,studies brain development.According to her research,it seems that exercise can make blood vessels,including those in the brain,stronger and more fully developed.Dr. Cameron claims this allows people who exercise to concentrate better. As she says:"While we already know that exercise is good for the heart,exercise can literally cause physical changes in the brain."The effects of exercise on brain development can even be seen in babies.Babies who do activities that require a lot of movement and physical activity show greater brain development than babies who are less physically active.With babies,even a{ittle movement can show big results. Margaret Barnes , a pediatrician（儿科医师）,believes in the importance of exercise.She thinks that many learning disabilities that children have in elementary school or high school can be traced back to a lack of movement as babies. "Babies need movement that stimulates their five senses.They need to establish a connection between motion and memory.In this way,as they get older,children will begin to associate physical activity with higher learning,"says Margaret. Older people can beef up their brains as well.Cornell University studied a group of seniors ranging in age from seventy to seventy-nine. Their study showed a short-term memory increase of up to 40 percent after exercising just three hours a week.The exercise does not have to be very difficult,but it does have to increase the heart rate.Also,just like the motion for infants,exercise for older people should involve some complexity.Learning some new skills or motions helps to open up memory paths in the brain that may not havebeen used for a long time.For most people,any type of physical activity that increases the heart rate is helpful. The main goal is to increase the brain's flow of blood.And your brain can benefit from as little as two to three hours of exercise a week.The expression"beef up"in paragraph 3 meansA:control. B: strengthen.C:operate. D: encourage.
共用题干Virtual DriverDriving involves sharp eyes and keen ears,analyzing with a brain,and coordination between hands,feet and brain.A man has sharp eyes and keen ears,analyzes through his brain,and maintains coordination between his hands and brains.He can control a fast-moving car with different parts of his body._______(46)Apparently there isn't anyone in the driver's cab,but there is in fact a virtual driver. This virtual driver has eyes,brains,hands and feet too.The minicameras on each side of the car are its eyes and are responsible for observing the road conditions ahead of it as well as the traffic to its left and right.If you open the boot,you can see the most important part of the automatic driving system:a built-in computer._______(47)The brain is responsible for calculating the speeds objects surrounding the car are moving at,analyzing their position on the road, choosing the right path,and giving orders to the wheel and the control system.In comparison with the human brain,the virtual driver's best advantage is that it reacts quickly. _______(48)However,it takes the world's best racecar driver at least one second to react,and this doesn't include the time he needs to take action.With its rapid reaction and accurate control,the virtual driver can reduce the accident rate on expressways considerably.In this case,is it possible for us to let it have the wheel at any time and in any place?_______(49)With its limited ability to recognize things,the car can now only travel on expressways.The intelligent car determines its direction by the clear lines that mark the lanes clearly and recognizes vehicles according to their regular shapes._______(50)This being the case,people still have high hopes about driverless cars,and think highly intelligent cars are what the cars of the future should be like.________（49）A:Experts say that we cannot do that just yet.B:In the near future,intelligent cars will be put into commercial operation.C:This is the brain of the car.D:But how does an intelligent car control itself?E:It completes the processing of the images sent by the cameras within 100 milliseconds.F:However,it cannot recognize moving people and bicycles on ordinary roads that have no clear markings on them.
共用题干A Ride in a Cable-carA ride in a cable-car is one of the exciting and enjoyable experiences a child can have.InSwitzerland,which is the home of the cable-car,it is used mostly to take tourists up the slope of a mountain,to a restaurant from which one can have a bird-eye view of the surrounding country, or to a top of a ski-run,from which,in winter,skiers glide down the snow covered the slope on skis .In Singapore,however,the cable-car takes one from the summit of a hill on the main island to a low hill on Sentosa,a resort island just off the southern coast.The cable-car is really a carriage which hangs from a strong steel cable suspended in the air.It moves along the cable with other cars on pulleys,the wheels of which are turned by electric motors. The cars are painted in eye-catching colours and spaced at regular intervals.Each car can seat up six persons.After the passengers have entered a car,they are locked in from outside by an attendant,they have no control over the movement of the car.Before long,the passengers get a breath-taking view through the glass windows of the modern city,the bustling harbour,and the several islands off the coast. The car is suspended so high in the air that slips on the sea look like small boats,and boats like toys.On a clear day,both the sky above and the sea below look beautifully blue.In contrast to the fast-moving traffic on the ground,the cars in the air move in a leisurely manner,allowing passengers more than enough time to take in the scenery during the brief trip to the island of Sentosa.After a few hours on Sentosa,it will be time again to take a cable-car back to Mount Faber. The return journey is no less exciting than the outward trip. The short trip does not bother passengers who want a good view because______.A: the cars move slowlyB: the cars move quicklyC: the cars are suspended very highD: the cars have glass windows
共用题干Motoring Technology1.2 million road deaths worldwide occur each year,plus a further 50 million injuries.To reduce car crash rate,much research now is focused on safety and new fuels-though some electric vehicle and biofuel research aims at going faster.Travelling at speed has always been dangerous.One advanced area of research in motoring safety is the use of digital in-car assistants.They can ensure you don't miss important road signs or fall asleep .Most crashes result from human and not mechanical faults.Some safety developments aim to improve your vision.Radar can spot obstacles in fog,while other technology"sees through"big vehicles blocking your view.And improvements to seat belts , pedal（脚踏）controls and tyres are making driving smoot- her and safer. The colour of a car has been found to be linked with safety,as have,less surpris- ingly,size and shape.But whatever is in the fuel tank,you don't want a thief in the driving seat and there have been many innovations（创新）.Satellite tracking and remote communications can also come into play if you crash,automatically calling for help.Accidents cause many traffic jams,but there are more subtle interplays between vehicles that can cause jams even on a clear but busy road.Such jams can be analyzed using statistical tools.Robotic drivers could be programmed to make traffic flow smoothly and will perhaps one day be everyone's personal chauffeur（司机）,but their latest efforts suggest that won't be soon. Which of the following statements is true of robotic drivers?A: It will take some time before robotic drivers are available.B: Robotic drivers are not allowed to drive on busy roads.C: Robotic drivers can never replace human drivers.D: Robotic drivers are too expensive to use.
