单选题"Most episodes of absent-mindedness------forgetting where you left something or wondering why you just entered a room------are caused by a simple lack of attention," says Schacter, "You're supposed to remember something, but you haven't encoded it deeply." Encoding, Schacter explains, is a special way of paying attention to an event that has a major impact on recalling it later. Failure to encode properly can create annoying situations. If you put your mobile phone in a pocket, for example, and don' t pay attention to what you did because you' re involved in a conversation, you'll probably forget that the phone is in the jacket now hanging in you wardrobe(衣柜). "Your memory itself isn't failing you," says Schacter, "Rather, you didn't give your memory system the information it needed." Lack of interest can also lead to absent-mindedness. "A man who can recite sports statistics from 30 years ago," says Zelinski,"may not remember to drop a letter in the mailbox." Women have slightly better memories than men, possibly because they pay more attention to their environment, and memory relies on just that. "Visual cues can help prevent absent-mindedness," says Schacter, "But be sure the cue is clear and available," he cautions. If you want to remember to take a medication(药物)with lunch, put the pill bottle on the kitchen table------don't leave it in the medicine chest and write yourself a note that you keep in a pocket Another common episode of absent-mindedness: Walking into a room and wondering why you' re there. Most likely, you were thinking about something else. "Everyone does this from time to time," says Zelinski. The best thing to do is to return to where you were before entering the room, and you'll be likely to remember.

单选题With only about 1,000 pandas left in the world, China is desperately trying to clone the animal and save the endangered species. That's a move similar to what a Texas A&M University researcher has been undertaking for the past five years in a project called "Noah's Ark". Dr. Duane Kraemer, a professor in Texas A & M's College of Veterinary Medicine and a pioneer in embryo(胚胎) transfer work and related procedures, says he salutes the Chinese effort and" I wish them all the best success possible. It's a worthwhile project, certainly not an easy one, and it's very much like what we're attempting here at Texas A&M--to save animals from extinction. " Noah's Ark is aimed at collecting eggs, embryos, semen(精子) and DNA of endangered animals and storing them in liquid nitrogen. If certain species should become extinct, Kraemer says there would be enough of the basic building blocks to reintroduce the species in the future. It is estimated that as many as 2,000 species of mammals, birds and reptiles will become extinct over the next 100 years. The panda, native only to China, is in danger of becoming extinct in the next 25 years. This week, Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit. They are now trying to implant the embryo into a host animal. The entire procedure could take from three to five years to complete. "The nuclear transfer of one species to another is not easy, and the lack of available panda eggs could be a major problem," Kraemer believes. "They will probably have to do several hundred transfers to result in one pregnancy. It take s a long time and it's difficult, but this could be groundbreaking science if it works. They are certainly not putting any live pandas at risk, so it is worth the effort , "adds Kraemer, who is one of the leaders of the Missyplicity Project at Texas A&M, the first ever attempt at cloning a dog. "They are trying to do something that's never been done, and this is very similar to our work in Noah's Ark. We're both trying to save animals that face extinction. I certainly applaud their effort and there's a lot we can learn from what they are attempting to do. It's a research that is very much needed. /

单选题Ranch. It was near Los Angeles in California. A few years later Hollywood was one of the famous places in the world. At the beginning of the 20th century there was a big farm called Hollywood. From the 1910's to the 1950's, Hollywood was the film center of the world. Every family knew the names of its film stars——Charlie Chaplin, Greta Garbo, Bergman and hundreds more. The reason why people went to Hollywood to make films was the sun. At first, people made films in New York on the east coast of the United States. But then they heard about Los Angeles, where there are 350 days of the sun every year. As they made all the films by sunlight, the west coast was a much better place to work. Also near Hollywood you can find mountains and sea and desert. They did not have to travel far to make any kind of film. When TV became popular, Hollywood started making films for television. Then in the1970's they discovered people still went to the cinema to see big expensive films. Nowadays they are still making films in Hollywood and people see them all over the world.

单选题The larger a machine and the more numerous its parts, the greater likelihood of a breakdown and the more expensive to repair. What has been said about market forces and management was necessarily oversimplified. The economies of modern industrial nations are large and very complex. To be sure, there is management, and there are market forces at work, but there are also many other factors that help or hinder economic function. In modern industrial societies, governments play a large role. There is a great amount of regulation, most of it meant for the protection of the public. All regulations affect the way businesses operate, often increasing their costs and reducing their profits. Lower profits, in turn, reduce the amount of money which is known as working capital that a company can use for expansion. Auto emission standards, for instance, have had a significant impact on the manufacture and pricing of automobiles. Other government policies such as taxation, budget deficits, and regulation of the money supply have an effect on how much money is available for people to spend on goods and services. International crises and other conditions also affect the working of an economy. A severe frost in Brazil can ruin a coffee crop and raise the price of that commodity. War can cut off the supply of such resources as petroleum, chromium, or copper. In the United States environmental protests have slowed the development of nuclear energy capacity and the mining of vast tracts of protected land. Weather affects agriculture, a hot, dry summer can damage the wheat crop; floods can destroy thousands of acres of crops suddenly; and insect pests can devastate cropland with a rapid onslaught. People's attitudes also have an impact on the marketing of goods. Health-conscious individuals, for example, may stop smoking, curtail their intake of alcohol, and eat less of certain kinds of food. Advertising affects what people buy, and it can create a market where none existed. Style and fashion are significant for many consumers. There are other economic problems that are more difficult to understand. For centuries economies have been subject to periods of prosperity followed by periods of decline. Although periods of prosperity can be explained rather easily, the reasons for panics, recessions, and depressions are of a complex nature. So many factors contributed to the Great Depression of the 1930s, for example, that no economist has ever been able to account for all of them. Because the causes of decline are uncertain, the remedies are equally uncertain. In the late 20th century all industrialized societies through their governments have tried to stabilize economies, keep them prosperous, and reduce unemployment. None of the remedies has worked to the extent that was hoped. How economies work and what remedies can be found to keep them operating efficiently are the tasks of economists, who must work together with businessmen and politicians.
