单选题Sport is heading for an indissoluble marriage with television and the passive spectator will enjoy a private paradise. All of this will be in the future of sport. The spectator (the television audience) will be the priority and professional clubs will have to readjust their structures to adapt to the new reality: sport as a business. The new technologies will mean that spectators will no longer have to wait for broadcasts by the conventional channels. They will be the ones who decide what to see. And they will have to pay for it. In the United States the system of the future has already started: pay-as-you-view. Everything will be offered by television and the spectator will only have to choose. The review Sports Illustrated recently published a full profile of the life of the supporter at home in the middle of the next century. It explained that the consumers would be able to select their view of the match on a gigantic, flat screen occupying the whole of one wall, with images of a clarity which cannot be foreseen at present; they could watch from the trainer"s bench, from the stands just behind the batter in a game of baseball or from the helmet of the star player in an American football game. And at their disposal will be the same options the producer of the recorded program has: to select replays, to choose which camera to use and to decide on the sound-whether to hear the public, the players, the trainer and so on. Many sports executives, largely too old and too conservative to feel at home with the new technologies, will believe that sport must control the expansion of television coverage in order to survive and ensure that spectators attend matches. They do not even accept the evidence which contradicts their view: while there is more basketball than ever on television, for example, it is also certain that basketball is more popular than ever. It is also the argument of these sports executives that television is harming the modest team. This is true, but the future of those teams is also modest. They have reached their ceiling. It is the law of the market. The great events continually attract larger audience. The world is being constructed on new technologies so that people can make the utmost use of their time and, in their home, have access to the greatest possible range of recreational activities. Sport will have to adapt itself to the new world. The most visionary executives go further. Their philosophy is: rather than see television take over sport, why not have sports take over television?

单选题Every time a person eats something he makes a nutritional decision. He accepts or rejects the food available to him at home for meals or snacks. Or he selects food for himself at many places in the community, such as supermarkets, drive-ins, restaurants, and food counters in drug stores. (83) These selections make a difference in how an individual looks, how he feels, and how well he can work and play. When a good assortment of food in appropriate amounts is selected and eaten, the consequences are more likely to be a desirable level of health and enough energy to allow one to be as active as he needs and wants to be. When choices are less than desirable, the consequences are likely to be poor health or limited energy or both. Studies of diets of individuals in the United States show that food selection is a highly individual matter, even among young children. (84) Furthermore, far too many individuals of all ages are making poor choices day after day and are either now living with the consequences or will be in the future. Nutritionists and workers in allied professions have been concerned about helping people learn to select and enjoy a wide variety of food combinations that can add up to a good diet. Most people believe that they are well-fed—that the choices they make are good ones. After all, they are not really sick; neither are they hungry. However, their nutrition is really poor in one respect or another. Milk and milk products, such as cheese, icecream, buttermilk, and yogurt, are often neglected. Then people may leave out in their diets many fruits and vegetables, particularly those that are good sources of vitamins A and C. These include dark green, leafy vegetables; deep yellow vegetables; and citrus fruits and vegetables, such as cabbages, tomatoes, and green peppers.

单选题{{B}}Passage 1{{/B}} Crossing Wesleyan university's campus usually requires walking over colorful messages chalked on the ground. They can be as innocent as meeting announcements, but in a growing number of cases the language is meant to shock. It's not uncommon, for instance, to see lewd (淫荡的) references to professors' sexual preferences scrawled across a path or the mention of the word Nig' that African-American students say make them feel uncomfortable. In response, officials and students at schools are now debating ways to lead their communities away from forms of expression that offend or harass (侵扰). In the process, they're butting up against the difficulties of regulating speech at institutions that pride themselves on fostering open debate. Mr. Bennet of Wesleyan says he had gotten used to seeing occasional chalkings filled with four-letter words. Campus tradition made any horizontal surface not attached to a building a potential billboard. But when chalkings began taking on a more threatening and lewd tone, Bennet decided to act. "This is not acceptable in a workplace and not acceptable in an institution of higher learning," Bennet says. For now, Bonnet is seeking input about what kind of message-posting policy the school should adopt. The student assembly recently passed a resolution saying the "right to speech comes with implicit responsibilities to respect community standards." Other public universities have confronted problems this year while considering various ways of regulating where students can express themselves. At Harvard Law School, the recent controversy was more linked to the academic setting. Minority students there are seeking to curb what they consider harassing speech in the wake of a series of incidents last spring. At a meeting held by the "Committee on Healthy Diversity" last week, the school's Black Law Students Association endorsed a policy targeting discriminatory harassment. It would trigger a review by school officials if there were charges of "severe or pervasive conduct" by students or faculty. The policy would cover harassment based on, but not limited to, factors such as race, religion, creed, sexual orientation, national origin, and ethnicity (种族划分). Boston attorney Harvey Silverglate, says other schools have adopted similar harassment policies that are actually speech codes, punishing students for raising certain ideas. "Restricting students from saying anything that would be perceived as very unpleasant by another student continues uninterrupted," says Silverglate, who attended the Harvard Law town meeting last week.

单选题The battle between Apple and law enforcement officials over unlocking a terrorist"s smart-phone is the climax of a slow turning of the tables between the technology industry and the United States government. On the one side, you have the United States government"s mighty legal and security apparatus fighting for data of the most sympathetic sort: the secrets buried in a dead mass murderer"s phone. The action stems from a federal court order issued on Tuesday requiring Apple to help the F.B.I. unlock an iPhone used by one of the two attackers who killed 14 people in San Bernardino, Calif., in December. In the other corner is the world"s most valuable company, whose chief executive, Timothy D. Cook, has said he will appeal the court"s order. Apple argues that it is fighting to preserve a principle that most of us who are addicted to our smartphones can defend: Weaken a single iPhone so that its contents can be viewed by the American government and you risk weakening all iPhones for any government intruder, anywhere. There will probably be months of legal tussling, and it is not at all clear which side will prevail in court, nor in the battle for public opinion and legislative favor. Yet underlying all of this is a simple dynamic: Apple, Google, Facebook and other companies hold most of the cards in this confrontation. They have our data, and their businesses depend on the global public"s collective belief that they will do everything they can to protect that data. Any crack in that front could be fatal for tech companies that must operate worldwide. If Apple is forced to open up an iPhone for an American law enforcement investigation, what"s to prevent it from doing so for a request from the Chinese or the Iranians? Once armed with a method for gaining access to iPhones, the government could ask to use it proactively, before a suspected terrorist at tack—leaving Apple in a bind as to whether to comply or risk an attack and suffer a public-relations nightmare. Yet it"s worth noting that even if Apple ultimately loses this case, it has plenty of technical means to close a backdoor over time. "If they"re anywhere near worth their salt as engineers, I bet they"re rethinking their threat model as we speak," said Jonathan Zdziarski, who studies the iPhone and its vulnerabilities.

单选题The police inspector, having received new information from a confidential source, decided to enlarge the ______ of his enquiry.(2006年财政部财政研究所考博试题)

单选题In the United States, it is important to be on time, or punctual, for an appointment, a class, etc. However, this may not be true in all countries. An American professor discovered this difference while teaching a class in a Brazilian (巴西的) university. The two-hour class was scheduled' to begin at 10 A. M. and end at 12. On the first day, when the professor arrived on time, no one was in the classroom. Many students came after the scheduled time. Several arrived half an hour later. Few apologized for their lateness. Were these students being rude? He decided to study the students, behavior. The professor talked to American and Brazilian students about lateness in both an informal and a formal situation: at a lunch with a friend and in a university class. He found that if they had a lunch appointment with a friend, the average American student defined lateness as 19 minutes after the agreed time. However, the average Brazilian student felt the friend was late after 33 minutes. In an American university, classes not only begin at the scheduled time in the United States, but also end at the scheduled time. In the Brazilian class, only a few students left the class at 12: 00; many remained past 12: 30 to discuss the class and ask more questions. While arriving late may not be very important in Brazil, neither is staying late.
