单选题The year 2000 will bring big changes in communication. Cell phones will be small enough to carry in your pocket. Videophones will let you see the person you are talking to on the phone. Tiny hand size computers will know your favorite subjects. The Internet and email will be everywhere. Technologists believe 2000 will be the year of video messaging. You will be able to see whom you’re talking to. Also in the near future small wireless boxes will pick up information from satellites. In 5 years, computers won’t need to be connected through wires. All of this will be good for rural areas and countries that don’t have cable or telephone now. In 20 years you may only need to think about something and the computer will do it. Constance Hale is the author of Sin and Syntax, "I believe that email has been an incredible boon to communication. People are writing today where they would have been telephoning yesterday. So people are engaging with words more than they have for the last couple generations." If people use email and the Internet more, it could make people better readers and writers. Some people think the most important part of communication is to make people understand each other better. Will technology make that easier? The translator also comes in handy in medical emergencies. Tam Dinh says, "Where people are injured it’s always important to get as much information as quickly as possible." Bob Parks is an Associate Editor of Wired Magazine, "Bob’s morning begins at about 6:45 am. and Bob is kind of mad, because Bob usually gets up at around 7:15 and likes to cut it close with his morning commute, but I look at my radio and it says that there’s a traffic jam on 101 South and I’m gonna need an extra 1/2 hour. And so my radio has got a net connection, wireless net connection as well as a good old power cord to the wall and it has received notice that there’s a traffic jam and it has calculated an extra 1/2 hour commute time." Some day everything may be connected to the Internet. Your refrigerator will add milk to your Internet grocery list when the date on the carton has passed. Light bulbs will be ordered before they bum out. It’s fun to try to guess the future. Usually the predictions are wrong. The one thing we know for sure is that we can’t imagine how technology will change.

单选题{{B}}Passage Three{{/B}} Mr. Smith gave his wife ten pound for her birthday —ten pretty pound notes. So the day after her birthday, Mrs Smith went shopping. She queued for a bus, got on and sat down next to an old lady. After a while, she noticed that the old lady’s handbag was open. Inside it she saw a wad of pound notes exactly like the one her husband had given her. So she quickly looked into her own bag — the notes were gone! Mrs Smith was sure that the old lady who was sitting next to her had stolen them. She thought she would have to call the police; but, as she disliked making a fuss and getting people into trouble, she decide to take back the money from the old lady’s handbag and say nothing more about it. She looked round the bus to make sure nobody was watching, then she carefully put her hand into the old lady’s bag, took the notes and put them in her own bag. When she got home that evening, she showed her husband the beautiful hat she had bought. "With the money you gave me for my birthday, of course." she said proudly. "Oh? What’s that, then?" he asked, as he pointed to a wad often pound notes on the table.

单选题 Valvular heart diseases are quite common, essentially resulting in impaired blood flow and were very difficult to treat. Some 30 years ago, it became possible to replace .diseased valves with prostheses to impose a greater control over blood flow. Early devices were of the mechanical variety, in which devices like ball-in-a-cage or tilting disc would be used to allow blood to flow under near-normal conditions. Although a few mechanical problems were encountered in the early days, the major difficulty lay with the tendency for any foreign material to initiate a blood clot. So, all valve recipients have to be given anticoagulant therapy. This is not particularly desirable for the patients, who may develop bleeding problems, and in any case is not always successful. Although good results are achieved with these valves, it was considered necessary to develop alternatives and the direction was that of natural tissues. It's not possible to transplant heart valves untreated because of rejection phenomena, but it became apparent that collagenous tissue could be cross-linked by glutaraldehyde and prepared in the form of a heart valve. Two sources of tissue were considered for this purpose, bovine pericardium ( collagenous tissue derived from the wall of a cow's heart) and porcine valves (heart valves taken from pigs) and the resulting "bioprosthetic valve" appeared to be very promising. It was particularly important that these patients didn't need anticoagulation. Unfortunately, these valves have not proved very durable, the cross-linked collagen suffering from slow calcification and deterioration so most of the replacement valves themselves need to be replaced within a decade. This would tend to suggest that the mechanical valves give superior performance, notwithstanding the anticoagulation problem, and a move back towards their use might have been expected. However, most of the valves in current use incorporate an alloy'( usually Stellite) forthe housing, and a carbon coated occuluder. The complex shapes of some of the housing have required combinations of casting and welding technologies to be used in their construction and serious problems have arisen with a valve design from one manufacturer, where a small number of catastrophic fractures have occurred within the housing. In patients where this valve has been used to treat aortic valve disease, this fracture is usually fatal and although the risks are small, the problem is important to the industry. Also, at a time when this dichotomy is exercising the minds of surgeons, scientists and regulatory bodies alike, the emergence of the disease BSE in cattle has placed even further restrictions on the use of animal tissue for this type of application and the whole question of prosthetic heart valves has been turned from a reasonable successful example of reconstructive implant surgery to a very confused area. This serves to highlight some of the very varied problems of facing the use of biomaterials.

单选题 Human needs seem endless. When a hungry man gets a meal, he begins to think about an overcoat, When a manager gets a new sports car, a big house and pleasure boats dance into view. The many needs of mankind might be regarded as making up several levels. When there is money enough to satisfy one level of needs, another level appears. The first and most basic level needs involves food. Once this level is satisfied, the second level of needs, clothing and some sort of shelter, appears. By the end of World War Ⅱ, these needs were satisfied for a great majority of Americans. Then a third level appeared. It included such items as automobiles and new houses. By 1957 or 1958 this third level of needs was fairly well satisfied. Then, in the late 1950s, a fourth level of needs appeared, the "life-enriching" level. While the other levels involve physical satisfaction, that is, the need in comfort, safety, and transportation, this level stresses mental needs for recognition, achievement, and happiness. It includes a variety of goods and services, many of which could be called "luxury" items. Among them are vacation trips, the best medical and dental care, and recreation. Also included here are fancy goods and the latest styles in clothing. On the fourth level, a lot of money is spent on services, while on the first three levels more is spent on goods. Will consumers raise their sights to a fifth level of needs as their income increases, or will they continue to demand luxuries and personal services on the fourth level? A fifth level would probably involve needs that can be achieved best by community action. Consumers may be spending more on taxes to pay for government action against disease, ignorance, crime, and prejudice. After filling our stomachs, our clothes closets, our garages, our teeth, and our minds, we now may seek to ensure the health, safety, and leisure to enjoy more fully the good things on the first four levels.

单选题{{B}}Part A{{/B}}{{B}}Directions:{{/B}} Read the following four texts. Answer the questions below each text by choosing A, B, C or D. Mark your answers on Answer Sheet 1.{{B}}Text 1{{/B}} The Catholic Church is changing in America at its most visible point: the parish church where believers pray, sing and clasp hands across pews to share the peace of God. Today there are fewer parishes and fewer priests than in 1990 and fewer of the nation's 65 million Catholics in those pews. And there's no sign of return. Some blame the explosive 2002 clergy sexual abuse scandal and its financial price tag. But a study of 176 Roman Catholic dioceses shows no statistically significant link between the decline in priests and parishes and the $ 772 million the church has spent to date on dealing with the scandal. Rather, the changes are driven by a constellation of factors: ·Catholics are moving from cities in the Northeast and Midwest to the suburbs, South and Southwest. ·For decades, so few men have become priests that one in five dioceses now can't put a priest in every parish. ·Mass attendance has fallen as each generation has become less religiously observant. ·Bishops--trained to bless, not to budget--lack the managerial skills to govern multimillion-dollar institutions. All these trends had begun years before the scandal piled on financial pressures to cover settlements, legal costs, care and counseling for victims and abusers. The Archdiocese of Boston, epicenter of the crisis, sold chancery property to cover $ 85 million in settlements last year, and this year will close 67 churches and recast 16 others as new parishes or worship sites without a full-time priest. Archbishop Sean O'Malley has said the crisis and the {{U}}reconfiguration plan{{/U}} are "in no way" related. He cites demographic shifts, the priest shortage and aging, crumbling buildings too costly to keep up. Fargo, N. D. , which spent $ 821,000 on the abuse crisis, will close 23 parishes, but it's because the diocese is short of more than 50 priests for its 158 parishes, some with fewer than a dozen families attending Mass. They know how this ~eels in Milwaukee. That archdiocese shuttered about one in five parishes from 1995 to 2003. The city consolidations "gave some people who had been driving back into the city from new homes in the suburbs a chance to say they had no loyalty to a new parish and begin going to one near their home,' says Noreen Welte, director of parish planning for the Milwaukee Archdiocese. "It gave some people who already were mad at the church for one reason or another an excuse to stop going altogether. "

单选题Historians have only recently begun to note the increase in demand for luxury goods and services that took place in eighteenth-century England. MeKendrick has explored the Wedgewood Firm"s remarkable success in marketing luxury pottery. Plumb has written about the proliferation of provincial theaters, musical festivals and children" s toys and books . While the feat of this consumer revolution is hardly in doubt, three key questions remain : Who were the consumers? What were their motives? And what were the effects of the new demand for luxuries? An answer to the first of these has been difficult to obtain. Although it has been possible to infer from the goods and service actually produced what manufacturers and servicing trades thought their customers wanted, only a study of relevant personal documents written by actual consumers will provide a precise picture of who wanted what. We still need to know how large this consumer market was and how far down the social scale the consumer demand for luxury goods penetrated. With regard to this last question, we might note in passing that Thompson, while rightly restoring laboring people to the stage of eighteenth-century English history, has probably exaggerated the opposition of these people to the inroads of capitalist consumerism in general: for example, laboring people in eighteenth-century England readily shifted from home-brewed beer to standardized beer produced by huge, heavily capitalized urban breweries. To answer the question of why consumers became so eager to buy, some historians have pointed to the ability of manufacturers to advertise in a relatively uncensored press. This, however, hardly seems a sufficient answer. MeKendriek favors a Viable model of conspicuous consumption stimulated by competition for status. The " middling sort" bought goods and services because they wanted to follow fashions set by the rich. Again, we may wonder whether this explanation is sufficient. Do not people enjoy buying things as a form of self-gratification? If so, consumerism could be seen as a product of the rise of new concepts of individualism and materialism, but not necessarily of the frenzy for conspicuous competition. Finally, what were the consequences of this consumer demand for luxuries? MeKendriek claims that it goes a long way toward explaining the coming of the Industrial Revolution. But does it? What, for example, does the production of high-quality potteries and toys have to do with the development of iron manufacture or textile mills? I t is perfectly possiMe Go have the psychology and reality of consumer society without a heavy industrial sector. That future exploration of these key questions is undoubtedly necessary should not, however, diminish the force of the conclusion of recent studies: the insatiable demand in the tenth-century England for frivolous as well as useful goods and services foreshadows our own world.
