共用题干Wide World of RobotsEngineers who build and program robots have fascinating jobs. These researchers tinker (修补)with machines in the lab and write computer software to control these devices.“They're the best toys out there,” says Howie Choset at Carnegie Mellon University in Pittsburgh. Choset is a roboticist,a person who designs,builds or programs robots.When Choset was a kid,he was interested in anything that moved一cars,trains,animals. He put motors on Tinkertoy cars to make them move. Later,in high school,he built mobile robots similar to small cars.Hoping to continue working on robots,he studied computer science in college. But when he got to graduate school at the California Institute of Technology in Pasadena,Choset's lab- mates were working on something even cooler than remotely controlled cars:robotic snakes. Some robots can move only forward,backward,left and right. But snakes can twist(扭曲)in many directions and travel over a lot of different types of terrain(地形).“Snakes are far more interesting than the cars,”Choset concluded.After he started working at Carnegie Mellon,Choset and his colleagues there began developing their own snake robots.Choset's team programmed robots to perform the same movements as real snakes,such as sliding and inching forward. The robots also moved in ways that snakes usually don't, such as rolling. Choset's snake robots could crawl(爬行) through the grass,swim in a pond and even climb a flagpole.But Choset wondered if his snakes might be useful for medicine as well. For some heart surgeries,the doctor has to open a patient's chest,cutting through the breastbone. Recovering from these surgeries can be very painful. What if the doctor could perform the operation by instead making a small hole in the body and sending in a thin robotic snake?Choset teamed up with Marco Zenati,a heart surgeon now at Harvard Medical School,to investigate the idea. Zenati practiced using the robot on a plastic model of the chest and then tested the robot in pigs.A company called Medrobotics in Boston is now adapting the technology to surgeries on people.Even after 15 years of working with his team's creations,”I still don't get bored of watching the motion of my robots,”Choset says.The application of a thin robotic snake makes heart surgeries less time-consuming.A: RightB: WrongC: Not mentioned

共用题干The Robot ManAccording to Hans Moravec,universal robots will take over all the physical activities that we engage in,leaving us with little to do.Moravec sees four generations on the road to true universal robots. The first generation will be here by 2010 and will consist of free-ranging robots that can navigate by building an internal mental map of their surroundings.In new situations they'll be able to adapt,unlike today's mobile industrial robots.These robots will have the computing power to cope with simple speech and text recognition,and will be used for tasks such as domestic clean-ing.The second generation will arrive around 2020 and will be distinguished by the ability to learn .Second generation robots are programmed with sets of primitive tasks and with feedback that provide"pleasure"and"pain"stimuli .For example,a collision provokes a negative response,a completed task would be positive.Move forward another ten years to 2030 and you get to generation three.This robot can build internal simulations of the world around it. Before beginning a task,it can imagine what will happen in order to predict problems.If it has a free moment,it can replay past experiences and try variations in order to find a better way of如ing things next time .It could even observe a person or another robot performing a task and learn by imitation.For the first time,we have here a robot that can think.By the time we get to generation four in 2040,Moravec predicts that robots will be able to: match human reasoning and behaviour;generalise abstract ideas from specific experience;and, conversely,compile detailed plans of action from general commands such as"earn a living"or "make more robots".The Moravec manifesto(宣告)runs something like this. As robots start to become useful in generation one,they'll begin to take on many tasks in industry.Driven by the availability of this cheap and tireless labour force,the economy will boom and the demand for robots will grow so rapidly that they will soon become lowcost commodity items.So much so that they'll move into the home,where the domestic robot will relieve us of many chores.With increasing automation in generations two and three,the length of the average working day will plummet,eventually to near zero. Most people will be unemployed as robots take over not just primary industry,but the service economy too.Moravec sees the fourth generation as an opportunity to surpass our human limitations.These future machines will be our"mind children".Like biological children of previous generations,they will embody humanity's best hope for a long-term future. What does Moravec think of these future robots?A: They will look like previous biological children.B: They will be humans' mind-children.C: They will create a dangerous world.D: They will rule the world.

共用题干第一篇Almost Human?Scientists are racing to build the world's first thinking robot.This is not science fiction: 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 android(机器人)which scientists have built at the Massachusetts Institute of Technology(MIT).Kismet is different from the traditional robot because it can show human emotions.Its eyes,ears and lips move to show when it feels happy,sad or bored. Kismet is one of the first of a new generation of androids一robots that look like human beings一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-old.The optimists(乐观主义者)say that by the year 2020 we will have created humanoids (机器人)with brains similar to those of an adult human being. These robots will be designed to look like 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 doing 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 entertain us by dancing and playing the piano.Some people worry about what the future holds:will robots become monsters(怪物)? Will people themselves become increasingly like robots?Experts predict that more and morepeople will be wearing micro-computers,connected to the Internet,in the future.People will have micro-chips in various parts of their body,which will connect them to a wide variety of gadgets(小装置).Perhaps we should not exaggerate(夸大)the importance of technology,but one wonders whether,in years to come,we will still be falling in love, and whether we will still feel pain.Who knows?What is the writer's attitude to robots in the future?A:Critical. B:Hostile.C:Objective. D:Enthusiastic.

Robots came into the world as a literary device whereby the writers and film-makers of the early 20th centu0'could explore their hopes and fears about technology,as the era of the automobile,telephone and aeroplane picked up its reckless jazz-age speed.From Fritz Lang's Metropolis and Isaac Asimov's l,Robot to WALL-E and the Terrnirator films,and in countless repetitions in between,they have succeeded admirably in their task.41.Since moving from the page and screen lo real life,robots have been a mild disappointment.They do some things that humans cannot do themselves,like exploring Mars,and a host of things people do not much want to do,like dealing with unexploded bombs or vacuuming floors.And they are very useful in bits of manufacturing.But reliable robots-especially ones required to work beyond the safety cages of a factory flom-have proved hard to make,and robots are still pretty stupid.So although they fascinate people,they have not yet made much of a mark on the world 42.That seems about to change.The exponential growth in the power of silicon chips,digital sensors and high-bandwidth communications improves robots just as it improves all sorts of other products.And,as our special report this week explains,three other factors are at play.43.One is that robotics Reventually some of them will build mass markets.Aerial robots-drones-may be in the vanguarcl here.They willlet farmers tend their crops in new ways,give citizens,journalists and broadcasters new perspectives on events big and small,monitor traffic and fires,look for infrastniccure in need of repair and much more besides.41选?A.Robots Come from Lhe Movies.B.Development of Robots Is Fast.C.Google Enters the Robot Industry.D.Robots Today Are Not Impressive EnouS;h.

问答题Robot  Even before the first robot was built, the subject of robotics was controversial. The word robot was coined in 1921 by a Czech playwright who wrote about a colony of machines endowed with artificial intelligence that eventually turned against3 their human creators. Although that account was fictional, the first industrial robots were in use by the early 1960s. Today, we continue to be intrigued by robots and their potential for both good and evil.  Basically, a robot is any machine that performs work or other actions normally done by humans. Most robots are used in factories to make products such as cars and electronics. Others are used to explore underwater, in volcanoes and even on other planets.  Robots consist of three main components: a brain, which is usually a computer; actuators and mechanical parts such as motors, wheels and gears; and sensors for detecting images, sound, temperature, motion and light. With these basic components, robots can interact with their environment and perform the tasks they are designed to carry out.  The advantages are obvious — robots can do things humans just don’t want to do, and they are usually more cost effective. Robots can also do things more precisely than humans and allow progress in medical science and other useful advances.  But, as with any machine, a robot can break down and even cause disaster. There’s also the possibility that wicked people will use robots for evil purposes. Yet this is also true with other forms of technology such as weapons and biological material.  Robots will probably be used even more in the future. They will continue to do tasks where danger, repetition, cost or the need for precision prevents humans from performing. As to whether they will be used for good or evil, that depends on the nature of the humans who create them.
