单选题(B) Scientists in India have invented a new way of producing electricity. Their invention does not get its power from oil, coal or other fuels. It produces electricity with the power of animals. India has about eighty million bullocks (小公牛). They do all kinds of jobs. They work in the fields. They pull vehicles through the streets. They carry water containers. Indian energy officials have been seeking ways to use less imported oil to provide energy. Scientists at the National Institute for Industrial Engineering in Bombay wondered if the millions of bullocks could help. Many villages in India lack electricity, but they have many bullocks. And often the animals are not working. One job done by bullocks is to pump water out of a well. The animals do this by walking around and around in a circle. As they walk, they turn a heavy stick that makes the pump move. This simple technology is centuries old. Scientists thought the same technology could be used to produce electricity. Bullocks walk in a circle only two or three times a minute. That is much too slow to produce electricity, but it can create enough power to turn a series of gears. A large gear sits next to a smaller gear. As the large gear turns, it causes the smaller gear to turn. That gear turns an even smaller one. Each gear moves faster because it is a little smaller. The smallest gear may turn extremely fast. Clocks operate with gears. So do cars, and so does the device invented by the Indian scientists to produce electricity. The United Nations Development Forum publication (出版社) reports that the idea is being tested at several places in India. The device is easy to operate and repair. And it can be moved easily. It costs about three hundred and seven dollars now to make such a device, but production of large numbers of them could cut the cost of each to about two hundred dollars.

单选题Business had better do some market research first to sell their products internationally, which is a lesson that learned by many companies, including some large American corporations have learnt the hard way. Names can sometimes be the problem. When General Motors introduced its Chevy Nova into Latin America, it overlooked the fact that Nova in Spanish means "It doesn"t go". Obviously, the Chevy Nova never went anywhere in Latin America. The slogan, on the other hand, is sometimes something that does work. No company knows this better than Pepsi-Cola, with its "Come alive with Pepsi!" campaign which was highly successful in the United States, and Pepsi translated its slogan literally for its international campaign. As it turned out, Pepsi was pleading with Germans to "Come out of the grave" and telling the Chinese that "Pepsi brings your ancestors back from the grave". The problem also involves picture and packaging. A smiling, round-checked baby has helped sell countless jars of Gerber baby food. So when Gerber marketed its products in Africa, it kept the picture of the baby on the jar. But Gerber did never realize that in many African countries, the picture on the jar shows what is inside the jar. Even cultural and religious factors can be involved. Thom McAn shoes have a Thorn McAn "signature" inside. To the Arabs, this signature looked like Arabic script for the word Allah, so some people felt the company was insulting God"s name by having people walk on it.

单选题A is for always getting to work on time. B is for being extremely busy. C is for the conscientious(勤勤恳恳的) way you do your job. You may be all these things at the office, and more. But when it comes to getting ahead, experts say, the ABCs of business should include a P, for politics, as in office politics. Dale Carnegie suggested as much more than 50 years ago: Hard work alone doesn"t ensure career advancement. You have to be able to sell yourself and your ideas, both publicly and behind the scenes. Yet, despite the obvious rewards of engaging in office politics—a better job, a raise, praise—many people are still unable—or unwilling—to "play the game." "People assume that office politics involves some manipulative (工于心计的) behavior," says Deborah Comer, an assistant professor of management at Hofstra University. "But polities derives from the word "polite". It can mean lobbying and forming associations. It can mean being kind and helpful, or even trying to please your superior, and then expecting something in return." In fact, today, experts define office politics as proper behavior used to pursue one"s own self-interest in the workplace. In many cases, this involves some form of socializing within the office environment—not just in large companies, but in small workplaces as well. "The first thing people are usually judged on is their ability to perform well on a consistent basis," says Neil P Lewis, a management psychologist. "But if two or three candidates are up for a promotion, each of whom has reasonably similar ability, a manager is going to promote the person he or she likes best. It"s simple human nature." Yet, psychologists say, many employees and employers have trouble with the concept of politics in the office. Some people, they say, have an idealistic vision of work and what it takes to succeed. Still others associate politics with flattery (奉承), fearful that, if they speak up for themselves, they may appear to be flattering their boss for favors. Experts suggest altering this negative picture by recognizing the need for some self-promotion.

单选题______ from the top of the tower, the south foot of the mountain is a sea of trees.

单选题(B) Education is not an end, but a means to an end. In other words, we do not educate children only for the purpose of educating them: our purpose is to fit them for life. As soon as we realize this fact, we will understand that it is very important to choose a system of education which will really prepare children for life. It is not enough just to choose the first system of education one finds; or to continue with one"s old system of education without examining it to see whether it is in fact suitable or not. In many modern countries it has for some time been fashionable to think that, by free education for all--whether rich or poor, clever or stupid--one can solve all the problems of society and build a perfect nation. But we can already see that free education for all is not enough: we find in such countries a far larger number of people with university degrees than there are jobs for them to fill. Because of their degrees, they refuse to do what they think "low" work; and, in fact, work with the hands is thought to be dirty and shameful in such countries. But we have only to think a moment to understand that the work of a completely uneducated farmer is far more important than that of a professor: we can live without education, but we die if we have no food. In fact, when we say that all of us must be educated to fit us for life, it means that we must be educated in such a way that, firstly, each of us can do whatever job is suited to his brain and ability and, secondly, that we can realize that all jobs are necessary to society, and that it is very bad to be ashamed of one"s work, or to scorn someone else"s. Only such a type of education can be called valuable to society.

单选题"Hi there. How"s it going?" "Oh, fine. Fine. How about this weather, huh?" "Well, I guess we can always use the rain." What"s that? This story? Oh, just a little look at small talk. You know, those seemingly meaningless conversations you have dozens of times a day. Maybe you"re waiting for the elevator. Or in a line at the bank. It all seems pretty trivial. Idle chatter about traffic doesn"t do much more than fill the air with empty words that are quickly forgotten. But you should know that small talk actually has a big place in our lives. Pat Oliver, assistant professor on arts, says that, "Left unchecked, small talk can be an invasion, It"s so powerful. It does something to you." "Every morning after spending an hour and a half on the freeway I start the day with small talk with my secretary," Oliver says, "If I don"t make small connection with another person, I can"t work." What causes it? As a rule, you"re either trying to force something into your life, or you"re using conversation as an invisible force field to keep them out. You can be wanting to connect with another person, and small talk is your introduction to more meaningful conversation. The way people use small talk is usually determined by where they happen to be at the time. Take the elevator, for instance. Now there"s prime territory. Nobody knows anyone and there"s no reason to start a conversation, but invariably, someone does. Making conversation in such peaceful social settings, according to Oliver, "can confirm your territory. It"s a way of feeling liked and accepted." The topics of small talk don"t matter. In fact, you don"t want anything more taxing than the weather or the traffic. It"s non-threatening talk in a threatening situation. However, the rules change quickly when you"re with lots of people doing lots of talking. Let"s say you"re at a party. Now it"s time to use small talk as a way of making others feel more comfortable around you, so you don"t look silly standing by the food table alone all night.
