单选题Do you forget to turn off the lights and heaters when you go out of a room? In 2040 it will not matter. They will turn themselves off—and on again when you return. You will choose the temperature for each room, the lighting and the humidity. A sensor will detect the presence of a human (and, with luck, ignore the dog! ) and turn the systems on, and when the humans leave it will turn them off again. The sensors will work through the central home computer, and they will do much more than just turn the fires and lights on and off for you. They will detect faulty electrical appliances, plugs or switches, isolate them so that they cannot harm anyone, and then warn you that they need repair. They will detect fire and if you are out of the house, the computer will call the fire brigade. It will also call the police should the sensors detect an intruder. This will not be too difficult because the locks on the outside doors will be electronic. You will open them using your personal card—the one you use for shopping—maybe using a number known only to you. It will be impossible to lose the key, and a housebreaker will have to tamper (拨弄) with the lock or with a window. It is not very difficult to make such tampering send a signal to the computer. The computer will be more than a fireman policeman servant. It will be an entertainer, and most of your entertainment will come right into your home. It does now, of course, but by 2040 "entertainment" will mean much more. For one thing, you will be able to take part actively, rather than just watching...

单选题 My parents' house had an attic, the darkest and strangest part of the building, reachable only by placing a stepladder beneath the trapdoor, and filled with unidentifiable articles too important to be thrown out with the trash but no longer suitable to have at hand. This mysterious space was the memory of the place. After many years all the things deposited in it became, one by one, lost to consciousness. But they were still there, we knew, safely and comfortably stored in the tissues of the house. These days most of us live in smaller, more modem houses or in apartments, and attics have vanished. Even the deep closets in which we used to pile things up for temporary forgetting are rarely designed into new homes. Everything now is out in the open, openly acknowledged and displayed, and whenever we grow tired of a memory, an old chair, a trunkful of old letters, they are cast into the dump for burning. This has seemed a healthier way to live, except maybe for the smoke everything out to be looked at, nothing strange hidden under the roof, nothing forgotten because of no place left in impenetrable darkness to forget. Openness is the new lifestyle, no undisclosed belongings, no private secrets. Candor is the role in architecture. The house is a machine for living, and what kind of machine would hide away its worn-out, deserted parts? But it is in our nature as human beings to clutter, and we long for places set aside, reserved for storage. We tend to accumulate and outgrow possessions at the same time, and it is an endlessly discomforting mental task to keep sorting out the ones to get rid of. We might, we think, remember them later and find a use for then, and if they are gone for good, off to the damp, this is a source of nervousness. I think it may be one of the reasons we drum our fingers so much these days. We might take a lesson here from what has been learned about our brains in this century. We thought we discovered, first off, the attic, although its existence has been mentioned from time to time by all the people we used to call great writers. What we really found was the trapdoor and a stepladder, and off we clambered, shining flashlights into the comers, vacuuming the dust out of bureau drawers, puzzling over the names of objects, tossing them down to the floor below, and finally paying around fifty dollars an hour to have them cast away for burning.

单选题Questions 16-20 are based on the following passage: In Guangzhou, capital of South China's Guangdong Province, Guangzhou Baiyun International Airport resumed its international flights to Singapore, Malaysia, Thailand, the Philippines and other Southeast Asian nations and regions early this month, said an airport official yesterday. And the airport's flow of international passengers for July has reached 80 per cent of the figure for the corresponding month of the previous year. Guangzhou Baiyun International Airport had to cancel some international services to Southeast Asian nations and regions because of the outbreak of SARS beginning in April, the official said. The official predicted his airport's international service would return to normal operation and handle even more international passengers in August. Currently, the Guangzhou airport is operating 22 international flights to 20 foreign metropolises. And nine foreign airlines have resumed their international flights to the airport.

单选题Beliefs are shared ideas about how the world operates. They may be' summaries and interpretations of the past, explanations of the' present or predictions for the future, and may be based on common sense, folk wisdom, religion, science, or some combination of these. Some beliefs apply to intangible (无形的) things (for example, whether the human spirit lives on after .death). All cultures distinguish between ideas for which people have reasonable proof (for Americans, for ex ample, the idea that smoking increases the risk of cancer) and ideas that have not been, or cannot be, tested (for Americans, for example, the idea that there is intelligent life on other planets). Where and how people draw the line varies, however. Bemuse beliefs shape both personal and social experience, basic differences in beliefs can account for some of the problems Vietnamese immigrants have had in American society. One exampie is beliefs concerning the nature of time. People in Western cultures believe time is irreversible (不可回转的). We think of time as a straight line. On every January 1st we add another year to the calendar. Traditionally, the Vietnamese have reckoned time in sixty-yesr cycles. Every sixty years the cycle starts over with .the year with which it began. Such a conception of time suggests that current events are not unique; that things come around again. American beliefs regarding time as linear create the sense that "time is ticking away"; the Vietnamese belief that time is cyclical creates an entirely different state of mind. Beliefs apply not only to concepts like time but also to mundane (世俗的，世间的) aspects of the material world. Residents of San Francisco were offended greatly to learn that rural immigrants from Laos and Cambodia had been stalking(蹑手蹑脚地走近) their dinner in Golden Gate Park. San Franciscans could not understand how the newcomers could hunt and eat squirrels(松鼠) and stray dogs; the Indochinese(印度支那人) could not understand why San Franciscans did not— a classic case of the same object (in this case, dogs) having different cultural meanings. Even within our own culture we can see great variation in how people think about the same re source. Some people see dogs as working animals, acquired to protect our apartments or livestock; others treat their dogs as special friends or even substitute children.

单选题People born in autumn live longer than those born in spring and are less likely to fall chronically ill when they are older, according to an Austrian scientist. Using census(人口普查)data for more than one million people in Austrian, Denmark and Australia, scientists at the Max Plank Institute for Demographic(人口统计的)Research found the month of birth was related to life expectancy over the age of 50. Seasonal differences in what mothers ate during pregnancy, and infections occurring at different times of the year could both have an impact on the health of a new-born baby and could influence its life expectancy in old age. "A mother giving birth in spring spends the last stage of her pregnancy in winter, when she will eat fewer vitamins than in summer," said one of the scientists. "When she stops breast-feeding and starts giving her baby normal food, it"s in the hot weeks of summer when babies are inclined to infections of the digestive system. " In Austria, adults born in autumn lived about seven months longer than those born in spring, and in Denmark adults with birthdays in autumn outlived those born in spring by about four months. In the southern hemisphere, the picture is similar. Adults born in the Australian autumn lived about four months longer than those born in the Australian spring. The study focused on people born at the beginning of the 20th century, using death certificates and census data. Although nutrition at all times of the year has improved since then, the seasonal pattern persists.

单选题We can see how the product life cycle works by looking at the introduction of instant coffee. When it was introduced, most people did not like it as well as "regular" coffee, and it took several years to gain general acceptance (introduction stage). At one point, though, instant coffee grew rapidly in popularity, and many brands were introduced (stage of rapid growth). After a while, people became attached to one brand and sales leveled off (stage of maturity). Sales went into a slight decline (衰退) when freeze-dried coffees were introduced (stage of decline). The importance of the product life cycle to marketers is this: Different stages in the product life cycle call for different strategies. The goal is to extend product life so that sales and profits do not decline. One strategy is called market modification. It means that marketing managers look for new users and market sections. Did you know, for example, that the backpacks that so many students carry today were originally designed for the military? Market modification also means searching for increased usage among present customers or going for a different market, such as senior citizens. A marketer may re-position the product to appeal to new market sections. Another product extension strategy is called product modification. It involves changing product quality, features, or style to attract new users or more usage from present users. American auto manufacturers are using quality improvement as one way to recapture world markets. Note, also, how auto manufacturers once changed styles dramatically from year to year to keep demand from falling. (262 words)
