单选题If you feel tired all the time, you don"t necessarily need to go to bed earlier -- the solution could he as simple as taking a five-minute afternoon nap. Children under five have an abundance of energy and one of the reasons is because they nap once or twice a day. Many sleep experts think we"re programmed to take a nap during the day, and gating back into this habit can be a solution for those who feel tired all the time. Prof. Chris Idzikowski of the Sleep Advisory and Assessment Center thinks that one can feel refreshed after just five minutes sleep. And research has shown that concentration and attention are improved after even a short nap. Sleep is genetically programmed in babies and it"s only as we get older that we learn to sleep for about eight hours a night and not at all during the day. But most research suggests that we are not physically designed to sleep for one long, single block. Before the working day became nine to five, all Western sleep patterns were more broken up. Research has shown that in the Middle Ages, people"s sleep quite often occurred in "three distinct parts — a nap in the afternoon, an early morning nap and another, longer sleep until dawn. So if you do find yourself feeling sleepy through the day, don"t feel you"re being lazy by giving in to sleep and having a nap. Your increased energy and alertness will make the rest of your day extra productive.

To say "裤子", people in the U.S. use "pants", but people in the U.K. say "trousers". People in the U.S. say "sure", but people in the U.K. say "of course". There are a lot of differences.

单选题If it were only necessary to decide whether to teach elementary science to everyone on a mass basis or to find the gifted few and take them as far as they can go, our task would be fairly simple. The public school system, however, has no such choice, for the two jobs must be carried on at the same time. Because we depend so heavily upon science and technology for our progress, we must produce specialists in many fields. Because we live in a democratic nation, whose citizens make the policies for the nation, large numbers of us must be educated to understand, to support, and when necessary, to judge the work of experts. The public school must educate both producers and users of scientific services. In education there should be a good balance among the branches of knowledge that contribute to effective thinking and wise judgement. Such balance is defeated by too much emphasis on any one field. This question of balance involves not only the relation of the natural sciences, the social sciences, and the arts but also relative emphasis among the natural sciences themselves. Similarly, we must have a balance between the current and classical knowledge. The attention of the public is continually drawn to new possibilities in scientific fields and the discovery of new knowledge; these should not be allowed to turn our attention away from the sound, established materials that form the basis of courses for beginners.

单选题The car was invented just a century ago. You may know all kinds of the car names, but many people don't know who the inventor of the first car was. The first car was invented not by a German, but by an American. His name was Henry Ford. Henry was born in a poor family. He was the eldest of six children. When he was a boy he became interested in fixing watches and machines. When he was twelve years old, his mother died. Soon he had to work in a machine shop for two dollars and fifty cents a week. In the evenings he repaired watches for another dollar a week. The hard life made him strong and able. At that time, there was another interest in the life of the young Ford. He dreamed of making a machine that could run without horses, so he named it "horseless carriage". He overcame a lot of difficulties and in April 1893, the "horseless, carriage" was finally finished: it was the first car. Later Henry Ford founded the Ford Motor Company. He was really the first inventor of the car in the world.
