6. 1 快速阅读课后习题 Directions: There are 4 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A], B], C] and D]. You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre. (4*5*1=20 points) Passage One Questions 1 to 5 are based on the following passage. Attitudes toward new technologies often fall along generational lines. That is, generally, younger people tend to outnumber older people on the front end of a technological shift. It is not always the case, though. When you look at attitudes toward driverless cars, there doesn't seem to be a clear generational divide. The public overall is split on whether they'd like to use a driverless car. In a study last year, of all people surveyed, 48 percent said they wanted to ride in one, while 50 percent did not. The fact that attitudes toward self-driving cars appear to be so steady across generations suggests how transformative the shift to driverless cars could be. Not everyone wants a driverless car now- and no one can get one yet-but among those who are open to them, every age group is similarly engaged. Actually, this isn't surprising. Whereas older generations are sometimes reluctant to adopt new technologies, driverless cars promise real value to these age groups in particular. Older adults, especially those with limited mobility or difficulty driving on their own, are one of the classic use-cases for driverless cars. This is especially interesting when you consider that younger people are generally more interested in travel-related technologies than older ones. When it comes to driverless cars, differences in attitude are more pronounced based on factors not related to age. College graduates, for example, are particularly interested in driverless cars compared with those who have less education: 59 percent of college graduates said they would like to use a driverless car compared with 38 percent of those with a high-school diploma or less. Where a person lives matters, too. More people who lived in cities and suburbs said they wanted to try driverless cars than those who lived in rural areas. While there's reason to believe that interest in self-driving cars is going up across the board, a person's age will have little to do with how self-driving cars can become mainstream. Once driverless cars are actually available for sale, the early adopters will be the people who can afford to buy them. 1. What happens when a new technology emerges? It further widens the gap between the old and the young. It often leads to innovations in other related fields. It contributes greatly to the advance of society as a whole. It usually draws different reactions from different age groups. 2. What does the author say about the driverless car? It does not seem to create a generational divide. It will not necessarily reduce road accidents. It may start a revolution in the car industry. It has given rise to unrealistic expectations. 3. Why does the driverless car appeal to some old people? It saves their energy. C) It adds t.o the safety of their travel. It helps with their mobility. D) It stirs up their interest in life . 4. What is likely to affect one's attitude toward the driverless car? The location of their residence. C) The amount of training they received. The field of their special interest. D) The length of their driving experience. 5. Who are likely to be the first to buy the driverless car? The seniors. C) The wealthy. The educated. D) The tech fans. Passage Two Questions 6 to 10 are based on the following passage. In agrarian (农业的), pre-industrial Europe, "you'd want to wake up early, start working with the sunrise, have a break to have the largest meal, and then you'd go back to work," says Ken Albala, a professor of history at the University of the Pacific. "Later, at 5 or 6, you'd have a smaller supper." This comfortable cycle, in which the rhythms of the day helped shape the rhythms of the meals, gave rise to the custom of the large midday meal, eaten with the extended family. "Meals are the foundation of the family," says Carole Counihan, a professor at Millersville University in Pennsylvania, "so there was a very important interconnection between eating together" and strengthening family ties. Since industrialization, maintaining such a slow cultural metabolism has been much harder, with the long midday meal shrinking to whatever could be stuffed into a lunch bucket or bought at a food stand. Certainly, there were benefits. Modern techniques for producing and shipping food led to greater variety and quantity, including a tremendous increase in the amount of animal protein and dairy products available, making us more vigorous than our ancestors. Yet plenty has been lost too, even in cultures that still live to eat. Take Italy. It's no secret that the Mediterranean diet is healthy, but it was also a joy to prepare and eat. Italians, says Counihan, traditionally began the day with a small meal. The big meal came at around 1 p.m. In between the midday meal and a late, smaller dinner came a small snack. Today, when time zones have less and less meaning, there is little tolerance for offices' closing for lunch, and worsening traffic in cities means workers can't make it home and back fast enough anyway. So the formerly small supper after sundown becomes the big meal of the day, the only one at which the family has a chance to get together. "The evening meal carries the full burden that used to be spread over two meals," says Counihan. 6. What do we learn from the passage about people in pre-industrial Europe? They had to work from early morning till late at night. They were so busy working that they only ate simple meals. Their daily routine followed the rhythm of the natural cycle. Their life was much more comfortable than that of today. 7. What does Professor Carole Counihan say about pre-industrial European families eating meals together? It was helpful to maintaining a nation's tradition. It brought family members closer to each other. It was characteristic of the agrarian culture. It enabled families to save a lot of money. 8. What does "cultural metabolism" (Line 1, Para.3) refer to? Evolutionary adaptation. C) Social progress. Changes in lifestyle. D) Pace of life. 9. What does the author think of the food people eat today? Its quality is usually guaranteed. It is varied, abundant and nutritious. It is more costly than what our ancestors ate. Its production depends too much on technology. 10. What does the author say about Italians of the old days? They eajoyed cooking as well as eating. C) They ate three meals regularly every day. They ate a big dinner late in the evening. D) They were expert at cooking meals. Passage Three Questions 11 to 15 are based on the following passage. As Artificial Intelligence (Al) becomes increasingly sophisticated, there are growing concerns that robots could become a threat. This danger can be avoided, according to computer science professor Stuart Russell, if we figure out how to turn human values into a programmable code. Russell argues that as robots take on more complicated tasks, it's necessary to translate our morals into Al language. For example, if a robot does chores around the house, you wouldn't want it to put the pet cat in the oven to make dinner for the hungry children. "You would want that robot preloaded with a good set of values," said Russell. Some robots are already programmed with basic human values. For example, mobile robots have been programmed to keep a comfortable distance from humans. Obviously there are cultural differences, but if you were talking to another person and they came up close in your personal space, you wouldn't think that's the kind of thing a: properly brought-up person would do. It will be possible to create more sophisticated moral machines, if only we can find a way to set out human vales as clear rules. Robots could also learn values from drawing patterns from large sets of data on human behavior. They are dangerous only if programmers are careless. The biggest concern with robots going against human values is that human beings fail to do sufficient testing and they've produced a system that will break some kind of taboo (禁忌). One simple check would be to program a robot to check the correct course of action with a human when presented with an unusual situation. If the robot is unsure whether an animal is suitable for the microwave, it has the opportunity to stop, send out beeps (嘟嘟声), and ask for directions from a human. If we humans aren't quite sure about a decision, we go and ask somebody else. The most difficult step ,in programming values will be deciding exactly what we believe is moral, and how to create a set of ethical rules. But if we come up with an answer, robots could be good for humanity. 11. What does the author say about the threat of robots? It may constitute a challenge to computer programmers. It accompanies all machinery involving high technology. It can be avoided if human values are translated into their language. It has become an inevitable peril as technology gets more sophisticated. 12. What would we think of a person who invades our personal space according to the author? A) They are aggressive. C) They are ignorant. B) They are outgoing. D) They are ill-bred. 13. How do robots learn human values? By interacting with humans in everyday life situations. By following the daily routines of civilized human beings. By picking up patterns from massive data on human behavior. By imitating the behavior of properly brought-up human beings. 14. What will a well-programmed robot do when facing an unusual situation? Keep a distance from possible dangers. C) Trigger its built-in alarm system at once. Stop to seek advice from a human being. D) Do sufficient testing before taking action. 15. What is most difficult to do when we turn human values into a programmable code? Determine what is moral and ethical. C) Set rules for man-machine interaction. Design some large-scale experiments. D) Develop a more sophisticated program. Passage Four Questions 16 to 20 are based on the following passage. Why do some people live to be older than others? You know the standard explanations: keeping a moderate diet, engaging in regular exercise, etc. But what effect does your personality have on your longevity (长寿)? Do some kinds of personalities lead to longer lives? A new study in the Journal of the American Geriatrics Society looked at this question by examining the personality characteristics of 246 children of people who had lived to be at least 100. The study shows that those living the longest are more outgoing, more active and less neurotic (神经质的) than other people. Long-living women are also more likely to be sympathetic and cooperative than women with a normal life span. These findings are in agreement with what you would expect from the evolutionary theory: those who like to make friends and help others can gather enough resources to make it through tough times. Interestingly, however, other characteristics that you might consider advantageous had no impact on whether study participants were likely to live longer. Those who were more self-disciplined, for instance, were no more likely to live to be very old. Also, being open to new ideas had no relationship to long life, which might explain all those bad-tempered old people who are fixed in their ways. Whether you can successfully change your personality as an adult is the subject of a longstanding psychological debate. But the new paper suggests that if you want long life, you should strive to be as outgoing as possible. Unfortunately, another recent study shows that your mother's personality may also help determine your longevity. That study looked at nearly 28,000 Norwegian mothers and found that those moms who were more anxious, depressed and angry were more likely to feed their kids unhealthy diets. Patterns of childhood eating can be hard to break when we're adults, which may mean that kids of depressed moms end up dying younger. Personality isn't destiny (命运), and everyone knows that individuals can learn to change. But both studies show that long life isn't just a matter of your physical health but of your mental health. 16. The aim of the study in the Journal of the American Geriatrics Society is __ . to see whether people's personality affects their life span to find out if one's lifestyle has any effect on their health to investigate the role of exercise in living a long life to examine all the factors contributing to longevity 17. What does the author imply about outgoing and sympathetic people? They have a good understanding of evolution. C) They generally appear more resourceful. B) They are better at negotiating an agreement. D) They are more likely to get over hardship. 18. What finding of the study might prove somewhat out of our expectation? Easy-going people can also live a relatively long life. Personality characteristics that prove advantageous actually vary with times. Such personality characteristics as self-discipline have no effect on longevity. Readiness to accept new ideas helps one eajoy longevity. 19. What does the recent study of Norwegian mothers show? Children's personality characteristics are invariably determined by their mothers. People with unhealthy eating habits are likely to die sooner. Mothers' influence on children may last longer than fathers'. Mothers' negative personality characteristics may affect their children's life spans. 20. What can we learn from the findings of the two new studies? Anxiety and depression more often than not cut short one's life span. Longevity results from a combination of mental and physical health. Personality plays a decisive role in how healthy one is. Health is in large part related to one's lifestyle.
