1、大学英语六级模拟试卷 589及答案与解析 一、 Part I Writing (30 minutes) 1 For this part, you are allowed 30 minutes to write a short essay entitled Say No to Drunk Driving. You should write at least 150 words following the outline given below. 1众所周知，酒后驾车十分危险 2但近年来越来越多的 人酒后驾车，原因是 3我认为 Say No to Drunk Driving 二、 Part II

2、Reading Comprehension (Skimming and Scanning) (15 minutes) Directions: In this part, you will have 15 minutes to go over the passage quickly and answer the questions attached to the passage. For questions 1-4, mark： Y (for YES) if the statement agrees with the information given in the passage; N (fo

3、r NO) if the statement contradicts the information given in the passage; NG (for NOT GIVEN) if the information is not given in the passage. 1 Trust Me, Im a Robot With robots now emerging from their industrial cages and moving into homes and workplaces, roboticists are concerned about the safety imp

4、lications beyond the factory floor. To address these concerns, leading robot experts have come together to try to find ways to prevent robots from harming people. Inspired by the Pugwash Conferences an international group of scientists, academics and activists founded in 1957 to campaign for the non

5、-proliferation of nuclear weapons the new group of robo-ethicists met earlier this year in Genoa, Italy, and announced their initial findings in March at the European Robotics Symposium in Palermo, Sicily. “Security and safety are the big concerns,“ says Henrik Christensen, chairman of the European

6、Robotics Network at the Swedish Royal Institute of Technology in Stockholm. Should robots that are strong enough or heavy enough to crush people be allowed into homes? Is “system malfunction“ a justifiable defence for a robotic fighter plane that contravenes (违反 ) the Geneva Convention and mistakenl

7、y fires on innocent civilians? “These questions may seem hard to understand but in the next few years they will become increasingly relevant,“ says Dr. Christensen. According to the United Nations Economic Commission for Europes World Robotics Survey, in 2002 the number of domestic and service robot

8、s more than tripled, nearly surpassing their industrial counterparts. By the end of 2003 there were more than 600,000 robot vacuum cleaners and lawn mowers a figure predicted to rise to more than 4m by the end of next year. Japanese industrial firms are racing to build humanoid robots to act as dome

9、stic helpers for the elderly, and South Korea has set a goal that 100% of households should have domestic robots by 2020. In light of all this, it is crucial that we start to think about safety guidelines now, says Dr. Christensen. Stop right there So what exactly is being done to protect us from th

10、ese mechanical menaces? “Not enough,“ says Blay Whitby. This is hardly surprising given that the field of “safety-critical computing“ is barely a decade old, he says. But things are changing, and researchers are increasingly taking an interest in trying to make robots safer. One approach, which soun

11、ds simple enough, is try to program them to avoid contact with people altogether. But this is much harder than it sounds. Getting a robot to navigate across a cluttered room is difficult enough without having to take into account what its various limbs or appendages might bump into along the way. “R

12、egulating the behaviour of robots is going to become more difficult in the future, since they will increasingly have self-learning mechanisms built into them,“ says Gianmarco Veruggio. “As a result, their behaviour will become impossible to predict fully,“ he says, “since they will not be behaving i

13、n predefined ways but will learn new behaviour as they go.“ Then there is the question of unpredictable failures. What happens if a robots motors stop working, or it suffers a system failure just as it is performing heart surgery or handing you a cup of hot coffee? You can, of course, build in redun

14、dancy by adding backup systems, says Hirochika Inoue. But this guarantees nothing, he says. “One hundred per cent safety is impossible through technology,“ says Dr. Inoue. This is because ultimately no matter how thorough you are, you cannot anticipate the unpredictable nature of human behaviour, he

15、 says. Or to put it another way, no matter how sophisticated your robot is at avoiding people, people might not always manage to avoid it, and could end up tripping over it and falling down the stairs. Legal problems In any case, says Dr. Inoue, the laws really just summarize commonsense principles

16、that are already applied to the design of most modern appliances, both domestic and industrial. Every toaster, lawn mower and mobile phone is designed to nunimize the risk of causing injury yet people still manage to electrocute (电死 ) themselves, lose fingers or fall out of windows in an effort to g

17、et a better signal. At the very least, robots must meet the rigorous safety standards that cover existing products. The question is whether new, robot-specific rules are needed and, if so, what they should say. “Making sure robots are safe will be critical,“ says Colin Angle of iRobot, which has sol

18、d over 2m “Roomba“ household-vacuuming robots. But he argues that his firms robots are, in fact, much safer than some popular toys. “A radio-controlled car controlled by a six-year old is far more dangerous than a Roomba,“ he says. If you tread on a Roomba, it will not cause you to slip over; instea

19、d, a rubber pad on its base grips the floor and prevents it from moving. “Existing regulations will address much of the challenge,“ says Mr. Angle. “Im not yet convinced that robots are sufficiently different that they deserve special treatment.“ Robot safety is likely to surface in the civil courts

20、 as a matter of product liability. “When the first robot carpet-sweeper sucks up a baby, who will be to blame?“ asks John Hallam, a professor at the University of Southern Denmark in Odense. If a robot is autonomous and capable of learning, can its designer be held responsible for all its actions? T

21、oday the answer to these questions is generally “yes“. But as robots grow in complexity it will become a lot less clear cut, he says. “Right now, no insurance company is prepared to insure robots,“ says Dr. Inoue. But that will have to change, he says. Last month, Japans Ministry of Trade and Indust

22、ry announced a set of safety guidelines for home and office robots. They will be required to have sensors to help them avoid collisions with humans; to be made from soft and light materials to minimize harm if a collision does occur; and to have an emergency shut-off button. This was largely prompte

23、d by a big robot exhibition held last summer, which made the authorities realize that there are safety implications when thousands of people are not just looking at robots, but mingling with them, says Dr. Inoue. However, the idea that general-purpose robots, capable of learning, will become widespr

24、ead is wrong suggests Mr. Angle It is more likely, he believes, that robots will be relatively dumb machines designed for particular tasks. Rather than a humanoid robot maid, “its going to be a heterogeneous (不同种类的 ) swarm of robots that will take care of the house,“ he says. 2 What was the Pugwash
