Certain forms of AI are indeed becoming ubiquitous. For example， algorithms （算法） carry out huge volumes of trading on our financial markets， self﹣driving cars are appearing on city streets， and our smartphones are translating from one language into another. These systems are sometimes faster and more perceptive than we humans are. But so far that is only true for the specific tasks for which the systems have been designed. That is something that some AI developers are now eager to change.
Some of today's AI pioneers want to move on from today's world of "weak" or "narrow" AI， to create "strong" or "full" AI， or what is often called artificial general intelligence （AGI）. In some respects， today's powerful computing machines already make our brains look weak. AGI could， its advocates say， work for us around the clock， and drawing on all available data， could suggest solutions to many problems. DM， a company focused on the development of AGI， has an ambition to "solve intelligence". "If we're successful，" their mission statement reads， "we believe this will be one of the most important and widely beneficial scientific advances ever made."
Since the early days of AI， imagination has outpaced what is possible or even probable. In 1965， an imaginative mathematician called Irving Good predicted the eventual creation of an "ultra﹣intelligent machine …that can far surpass all the intellectual （智力的） activities of any man， however clever." Good went on to suggest that "the first ultra﹣intelligent machine" could be "the last invention that man need ever make."
Fears about the appearance of bad， powerful， man﹣made intelligent machines have been reinforced （强化） by many works of fiction﹣Mary Shelley's Frankenstein and the Terminator film series， for example. But if A I does eventually prove to be our downfall， it is unlikely to be at the hands of human﹣shaped forms like these， with recognisably human motivations such as aggression （敌对行为）. Instead， I agree with Oxford University philosopher Nick Bostrom， who believes that the heaviest risks from AGI do not come from a decision to turn against mankind but rather from a dogged pursuit of set objectives at the expense of everything else.
The promise and danger of true AGI are great. But all of today's excited discussion about these possibilities presupposes the fact that we will be able to build these systems. And， having spoken to many of the world's foremost A I researchers， I believe there is good reason to doubt that we will see AGI any time soon， if ever.

Does everyone want a challenging job? In spite of all the attention focused by the media, academicians, and social scientists on human potential and the needs of individuals, there is no evidence to support that the vast majority of workers want challenging jobs. Some individuals prefer highly complex and challenging jobs; others develop in simple, routine work.
The individual-difference variable（变量）that seems to gain the greatest support for explaining who prefers a challenging job and who doesn’t is the strength of an individual’s needs for personal growth and self-direction at work. Individuals with these higher-order growth needs are more responsive for challenging work. What percentage of ordinary workers actually desire higher-order need satisfactions and will respond positively to challenging jobs? No current data is available, but a study from the 1970s estimated the figure at about 15%. Even after adjusting for changing work attitudes and the growth in white-collar jobs, it seems unlikely that the number today exceeds 40%.
The strongest voice advocating challenging jobs has not been workers—it’s been professors, social science researchers, and media people. Professors, researchers, and journalists undoubtedly made their career choices, to some degree, because they wanted jobs that gave them autonomy, recognition and challenge. That, of course, is their choice. But for them, to force their needs onto the workforce in general is presumptuous (冒失的).
Not every employee is looking for a challenging job. Many workers meet their higher-order need off the job. There are 168 hours in every individual’s week. Work rarely consumes more than 30% of this time. That leaves considerable opportunities, even for individuals with strong growth needs, to find higher-order need satisfaction outside the workplace. So don’t feel you have a responsibility to create challenging jobs for all your employees. For many people, work is something that will never excite or challenge them. And they don’t expect to find their growth opportunities at work. Work is merely something they have to do to pay their bills. They can find challenges outside of work on the golf course, fishing, at their local pub, with their friends in social clubs, with their family, and the like.What makes people choose challenging jobs?
| A．Positive responses. | B．Work attitudes. |
| C．Higher-order growth needs. | D．Personal self-direction. |
Who is the least likely to prefer a challenging job?
| A．College professors. | B．Construction workers. |
| C．Social researchers. | D．Media journalists. |
The passage is intended for _______.

| C．employers | D．graduates |
Which is the best title for the passage?
| A．Not Everyone Wants a Challenging Job |
| B．Complex Jobs Offer Growth Opportunities |
| C．Employers Should Create Challenging Jobs |
| D．Challenging Jobs Give a Sense of Recognition |
Whether we should allow marine (海洋的) parks to stay open has been widely debated in our community recently. A variety of different arguments have been put forward about it.
Smith, a sociologist, argued that dolphin parks provide the only opportunity for much of the public to see marine mammals. As this argument goes, most Australians live in cities and never get to see these animals. Marine parks allow the average Australian to appreciate our marine wildlife. However, in fact, there are many places where they can be seen in the wild. Moreover, these places do not charge an overpriced entry fee — they are free.
Dr. Alison Lane, the director of the Cairns Marine Science Institute, insists that we need marine parks for scientific research. She argues that much of our knowledge of marine mammals comes from studies which were undertaken at marine parks. The knowledge which is obtained at marine parks can be useful for planning for the preservation of marine mammal species. However, Jones, a zoologist, explains that park research is only useful for understanding captive animals and is not useful for learning about animals in the wild. Their diets are different, they have significantly lower life lengths and they are more likely to have a disease. In addition, marine mammals in dolphin parks are trained and this means that their patterns of social behavior are changed.
The Marine Park Owners Association holds that marine parks attract a lot of foreign tourists. This position goes on to state that these tourists spend a lot of money, increasing our foreign exchange earnings and assisting our national balance of payments. However, foreign tourists would still come to Australia if the parks were closed down. Indeed, surveys of overseas tourists show that they come here for a variety of other reasons and not to visit places like Seaworld. Tourists come here to see our native wildlife in its natural environment and not to see it in cages and concrete pools. They can see animals in those conditions in their own countries.
In a word, perhaps an agreement cannot be reached now. However, a question does deserve our consideration: If we continue with our past crimes against these creatures, how will our future generations view us?Who support(s) the idea of closing marine parks?
| A．Most Australians. | B．Jones. |
| C．Smith. | D．Alison Lane. |
Which is NOT the reason to keep marine parks?
| A．For entertainment purpose. |
| B．For scientific research purpose. |
| C．For economic purpose. |
| D．For political purpose. |
The author tries to persuade readers to accept his argument mainly by________.
| A．pointing out the problems with keeping the marine parks |
| B．using evidence he has collected at the marine parks |
| C．discussing the advantages of animals' natural homes |
| D．questioning the way the animals are studied |
| For: Doug Smith, Director of wolf recovery, Yellowstone National Park In the world today there is so much we are losing; more and more species disappear from the earth every year. The time has come to put something back，to restore to treat some of the old wounds enforced on nature over the years. Wolves are animals killing and eating other animals in North America. They play an important role in keeping the continent healthy. Most places don’t have enough wild country to make their restoration possible, which means it’s even more important to restore wolves where conditions are right, places like Yellowstone, which has both a high level of wildness, as well as abundant creatures that wolves hunt and eat for living. Some who oppose wolf restoration have a human centered point of view that the earth is here for humans, we can use it whenever we want and for whatever purpose. But wolves offer us a chance to live another way—a way to learn to live with other life forms. |

Against: Larry Bouret, Vice President, Wyoming Farm Bureau What does wolf introduction to Yellowstone mean? To the average citizen it probably just means introducing wolves to Yellowstone. There would be no unfavorable effects because few people live near Yellowstone. But to farmers it means introducing wolves, which wander over vast areas—in and out of the park—onto their farms. Wolves eat meat—as in the cattle, sheep that keep farmers in business. Introduction apparently also means lawsuits by environmental groups attempting to remove livestock from federal lands. To farmers, who own private lands in the same area, it means the possibility of financial ruin. To farmers it is a form of land use restrictions. To farmers introducing wolves means taking away the farmers’ livelihoods without just compensation. Why do people not want a nuclear power plant built in their backyard? For the same reason farmers do not want wolves introduced into their backyard. |
What are the two passages mainly about?
| A．Whether to remove livestock away from federal lands. |
| B．Whether to introduce wolves to Yellowstone. |
| C．How to increase the number of wolves. |
| D．How to keep the balance of nature. |
According to the passage Doug Smith is _______.
| A．a national park administrator. |
| B．a wildlife conservationist. |
| C．an enthusiastic hunter. |
| D．a private land owner. |
What are the farmers concerned about?
| A．Being controlled by wolves. |
| B．Having to sell their farmland. |
| C．Suffering heavy financial loss. |
| D．Being forced to leave their homes. |
Why does Larry Bouret mention “nuclear power plant”?
| A．To summarize his opinion. |
| B．To make his view persuasive. |
| C．To tell the danger of nuclear power plant. |
| D．To introduce the background of wolf recovery. |

Head held high, hands firmly gripping her walker, Mary Arnott, 99, walks slowly with dignity through the women’s changing room at the Etobicoke Olympium pool, past the teenage girls who have been blow-drying their hair for half an hour, into the mist of the showers, then out the door and first one into the heated pool. She jumps over to the shallow end, stopping to talk to friends—everyone knows Arnott here; she swims twice a week and treats it as a job—about their children, the viciousness(谬误) of bridge and their health.
In fact, Arnott is an exception to the exception. Not only has she lived 20 years past the average lifespan for Canadians, she’s healthy, her mind is sharp and she lives independently.
Born in Brooklyn on May 28, 1909, Arnott was raised on Staten Island. She survived scarlet fever(猩红热), helped bring up four siblings after her mother died in 1923 and worked as a secretary in New York City for 12 years, earning＄35 a week and a＄150 bonus at Christmas.
Now she’s happy living in a one-room apartment with a kitchen and a bathroom in her daughter’s house. She wears a hearing aid, does the cryptic(有隐义的) crossword with a magnifying glass, and can’t really explain why she has live so well so long.
Until recently, she has still liked to drink red wine—she used to drink two glasses before supper each day. It’s more likely genes, she admits. Her interest in other people and life in general may have had something to do with it. Asked if a star photographer can take her picture at the pool, Arnott seems cheerful.
“I look good in a swimsuit,” she says, nodding her head firmly. “I look better in a swimsuit than I do in pants. ”What can we learn from the first paragraph?
| A．Mary Arnott can’t swim but she likes water. |
| B．Mary Arnott is afraid to swim at the swimming pool. |
| C．Mary Arnott likes to swim and is known to the local people. |
| D．Mary Arnott just likes to talk to her friends at the bank of the swimming pool. |
Which of the following is TRUE as for Mary Arnott as an exception to the exception?
| A．She lives with her daughter. |
| B．She’s healthy and her mind is sharp. |
| C．She likes to live with her children and has a happy life. |
| D．She has lived 30 years past the average lifespan for Canadians. |
If someone asks about swimming, Mary Arnott may ________.
| A．like swimsuit better | B．like pants |
| C．like to sit at the bank | D．like to swim with girls |
