A young man was going to join the army and had to take a medical examination. The doctor was sitting at a desk when he went in. He said to the man. "Take your coat and shirt off, and sit on the chair." The young man did so. The doctor looked at him for a moment without getting up from his chair and then said, "All right. Put on your clothes again." "But you haven't examined me at all!" the young man said in surprise. "There is no need to do so," the doctor said with a smile. "When I told you to take your coat and shirt off, you heard me all right, so there is nothing wrong with your ears. You saw the chair, so your eyes are good. You could take your clothes off and sit on the chair, so you must be in good health. And you understand what I told you to do and did it without a mistake, so you must be clever enough for the army." At first the young man _ . A) did not understand what the doctor mean B) did not do as he was told to do C) realized why the doctor told him to do something D) understood what the doctor meant

In his 1930 essay "Economic Possibilities for Our Grandchildren ", John Keynes, acconmist, ewrote that human needs fall into two classes: needs ,which are indupe what other have , and needs ,which make us feel superior to our fellows He thought alough needs may indeed be insatible this isnottrue of Keynes wans surely correct that only a small part of total spending id decided by the super iority He was gretly mistaken ,however ,in seeting this desive as the only source of demands Decisions to spend are also driven by ideas of quality which can influnce the den almost all goods, including even basic goods like food. When a couple goes out for an anm dinner,for example,the thought of feeling superior to others probably never comes to them. The goal is to share a special meal that stands out from other meals. There are no obvious limits to the _ of demand for quality.For example ,porsche famous car producer,has a model which was considered perhaps the best sport car on the mark Priced at over $120,000,it handles perfectly well and has great speen acceleration.But in 200 the producer introduced some changes which made the model slightly better in handling acceleration.People who really care about cars find these small improvemenmts exciting.To them,however,they must pay almost four times the price. By placing the desire to be superior to other at the heart of his description of nisation demands,Keynes actually reduced such demands.However,the desire for higher quality has natural limits. The author of the passage that _ . A) needs have no limits B) demands for quality are not insatiable C) human desires influsnce ideas of quality D) needs decide most of our spending

Q: As children grow up, they become curious about different kinds of things. When they are babies, they are interested in the parts of their bodies and in the smiles of their mothers. The they become interested in the physical world around them: the plants, the animals, the sky. Later, they become interested in the things that people have made: wheels, bicycles, cars. And when they are adults, their curiosity continues. Sometimes this curiosity leads to a career (, ) in science. Scientists spend their lives trying to find out about the world. Those who work with the earth sciences study the earth, the oceans, and the skies. Other scientists who study living things work with the biological sciences. A third group of scientists study the physical sciences, e. g. physics, chemistry . These scientists have already discovered a lot about our world. For example, they tell us why your heart beats fast when you run. They say that when you are quiet, your heart normally beats sixty-five or seventy-five times a minute. Your heart is a pump that pumps blood to all parts of the body. The blood carries oxygen and nutrition. When you run, your muscles work very hard and use the nutrition that the blood carries to them. The muscles need oxygen, too . So your brain sends a signal to the heart. The signal means that the muscles need more nutrition and oxygen. Then the heart beats fast and sends blood quickly to the muscles. It may beat 90 to 140 times a minute. Of course, scientists cannot answer all of our questions. If we ask, "Why does the ocean water taste salty?" Scientists will say that the salt comes from rocks. When a rock gets very hot or very cold, it cracks. Rain falls into cracks. The rain then carries the salt into the earth and into the rivers. The rivers carry the salt into the ocean. But then we ask , "What happens to the salt in the ocean? The ocean does not get saltier every year." Scientists are not sure about the answer to this question. We know a lot about our world, but there are still many answers that... When you run, your muscles need _ . A) more nutrition and oxygen B) more signals C) more salt D) water

*Question*
Mr. and Mrs. Wu were fed up with their neighbor. He was always borrowing things from them. "It's not right." Mr. Wu said to his wife one evening. "At some time or another that man has borrowed nearly everything we have. Almost every day he comes over to borrow something." "You are quite right," his wife replied, "and most of the things he's never returned." "What I want to know," her husband said, "is why he can't buy the things he needs like everyone else." "Because people like us are foolish enough to lend him what he needs." she replied. "As long as we are willing to lend, he'll keep on borrowing." "Then we'll never lend him anything again." Mr. Wu said. "The next time he asks to borrow something, I'll say no." "We must have a good reason for saying no," his wire said, "and we must always try to be polite to him. We don't want to make an enemy of the man." It was not long before their decision not to lend their neighbor anything ever again was put to the test. The next morning there was a knock on the door.
