单选题. A new World Bank report warns that children who do not get enough good food in the first two years of life suffer lasting damage. They may be underdeveloped or underweight. They may suffer from poor health or limited intelligence. In addition, poorly nourished children are more likely to drop out of school and earn less money as adults. The report notes that too little food is not the only cause of poor nutrition. Many children who live in homes with plenty of food suffer for other reasons. For example, the study says that mothers often fail to give their newly born babies their first breast milk. This milk-like substance is called colostrum. It is full of nutrients that improve a baby's ability to fight infections and disease. The study also links malnutrition to economic growth in poor countries. A lack of nutrition in early childhood can cost developing nations up to three percent of their yearly earnings. Many of these same countries have economies that are growing at a rate of two to three percent yearly. The study suggests that poor countries could possibly double their economic growth if they improved nutrition. Africa and South Asia are affected the most by poor nutrition. The study says about half of all children in India do not get enough good food. The World Bank study also notes that rates of malnutrition in South Asia are almost double those in central and southern Africa. Other parts of the world are also severely affected, including Indonesia, Uzbekistan, Yemen, Guatemala and Peru. The study recommends that developing countries change their policies to deal with malnutrition. Instead of directly providing food, the study suggests educational programs in health and nutrition for mothers with young babies. It also recommends cleaner living conditions and improvements in health care. World Bank nutrition specialist Meera Shekar said the period of life between Pregnancy and two years is extremely important. Governments with limited resources should take direct action to improve nutrition for children during this period.1. What's the main topic of the passage? ______

单选题. The "standard of living" of any country means the average person's share of the goods and services which the country produces. A country's standard of living, 21 , depends first and 22 on its capacity to produce wealth. "Wealth" in this sense is not money, for we do not live on money, 23 on things that money can buy: "goods" such as food and clothing and "services" such as transport and 24 . A country's capacity to produce wealth depends upon many factors, most of 25 have an effect on one another. Wealth depends 26 a great extent upon a country's natural resources, such as coal, gold, and other minerals, water supply and so on. Some regions of the world are well 27 with coal and minerals, and have a fertile soil and a 28 climate; other regions possess perhaps only one of these things, and some regions possess none of them. The U.S.A. is one of the wealthiest regions of the world because she has vast natural resources 29 her borders, her soil is fertile, and her climate is 30 . The Sahara Desert, on the other hand, is one of the least wealthy. Next to natural resources 31 the ability to turn them to use. China is perhaps as well 32 as the U.S.A. in natural resources, but suffered for many years from civil and 33 wars, and for this and other reasons was unable to develop her resources. 34 and stable political conditions, and 35 from foreign invasion, enable a country to develop her resources peacefully and steadily, and to produce more wealth than another country equally well 36 by nature but less well ordered. Another important factor is the technical 37 of a country's people. Old countries that have, through many centuries, trained up numerous skilled craftsmen and technicians 38 better placed to produce wealth than countries whose workers are largely unskilled. Wealth also produces wealth. As a country becomes wealthier, its people have a large 39 for saving, and can put their savings into factories and machines which will help workers to 40 more goods in their working day.21.

单选题. In spite of the strong opposition to new and strict environmental laws, however, it is still possible to attack the problem of chemical pollution; but we must attack it from three directions. First, we need more independent research into the effects of chemicals by scientists who are not paid by the government or by large industrial companies. Second, scientists need to educate the general public and inform them about the dangers of chemicals in the environment. If the public knows that a certain chemical threatens the health of their children, then it will put pressure on politicians, in local and national government. If the politician want to remain in office, they will take action to correct the long-term economic costs of chemicals. It will be extremely expensive to clean areas of land which are contaminated (污染) by chemicals; it will be even more costly to give medical treatment to people who are suffering from serious illnesses after exposure to dangerous chemicals. If governments realize this, the short-term economic benefits of chemicals will seem much less attractive to them. If we can put pressure on governments in these three ways, perhaps they will begin to behave more responsibly. They will perhaps pass new laws against pollution and enforce them strictly. Perhaps, then, the chemical producers will begin to behave more responsibly.1. Which of the following might be the best title for the passage? ______

单选题. The accuracy of scientific observations and calculations is always at the mercy of the scientist's time-keeping methods. For this reason, scientists are interested in devices that give promise of more precise time-keeping. In their search for precision, scientists have turned to atomic clocks that depend on various vibrating atoms or molecules to supply their "ticking". This is possible because each kind of atom or molecule has its own characteristic rate of vibration. Atom in ammonia, for example, vibrates or "ticks" 24 billion times a second. One such atomic clock is so accurate that it will probably lose no more than a second in 3000 years. It will be of great importance in fields such as astronomical observation and long-range navigation. The heart of this Atomichron is a cesium (铯) atom that vibrates 9.2 billion times a second when heated to the temperature of boiling water. An atomic clock that operates with an ammonia molecule may be used to check the accuracy of predictions based on Einstein's relativity theories, according to which a clock in motion and a clock at rest should keep time differently. Placed in an orbiting satellite moving at a speed of 18,000 miles an hour, the clock could broadcast its time readings on a similar model. Whatever differences develop would be checked against the differences predicted.1. The selection says that the accuracy of scientific observation depends on ______.

单选题. Would you like to spend all evening reading a lovely story with beautiful illustrations and make $ 35, 000 at the same time? Millions of people all over the world tried to do just that. Only one succeeded. The book is called Masquerade, and was written by British painter Kit Williams. Within its pages are clues to the location of a golden jewel, and whoever figured out the clues could find and keep the treasure. Some years ago, Williams was asked to write a children's book. Wanting to do something no one else had done before, he decided to bury a golden treasure and tell where it was in the book. He began painting without a clear idea of what the story would be about, where he would bury the treasure, or even what the treasure would be. As he painted, he decided that in the story a hare, or rabbit, would travel through earth, air, fire and water to deliver a gift from the moon to the sun. After three years, he finished the paintings and then wrote the story. The treasure became an 18-carat goldhare, adorned with precious stones, and it was made by Kit Williams himself. This beautiful jewel, worth around $ 35, 000, depending on gold prices, was buried somewhere in Britain, free to anyone who could decipher the clues. Williams's book kept people of all ages amused trying to solve the mystery of Masquerade. The rabbit was finally found in the spring of 1982, by a 48-year-old design engineer. It was buried in a park about thirty-five miles from London.1. The function of the first sentence in this passage is to ______.

单选题. Toronto: A 300-pound adult Siberian tiger escaped from its four-meter high chain-link pen (圈) at the Toronto Zoo yesterday, on one of the busiest days of the year. Though no one was hurt, the dangerous animal was separated from the public for a time by nothing more than a four-foot fence. The escape occurred after one of the animal's handlers left the pen gate open. It prompted a swift response from officials. Staff were sent immediately to arrest the run-away tiger. General Manager Calvin White told reporters that staff were preparing for the worst. "I ordered a tranquilizer(麻醉剂) gun so we would have tranquilized her, but thankfully we didn't have to," Mr. White said. The tiger was successfully led back into its cage after the brief escape. The incident occurred during the Toronto Zoo's 28th annual Christmas Treats Walk, where admission is free in return for donations of food that does not easily go bad. Thousands of people attend each Boxing Day to see the animals fed by their handlers.1. The tiger escape happened ______.

单选题. In recent years many countries of the world have been faced with the problem of how to make their workers more productive. Some experts claim the answer is to make jobs more varied. But do more varied jobs lead to greater productivity? There is evidence to suggest that while variety certainly makes the worker's life more enjoyable, it does not actually make him work harder. As far as increasing productivity is concerned, variety is not an important factor. Other experts feel that giving the worker freedom to do his job in his own way is important and there is no doubt that this is true. The problem is that this kind of freedom cannot easily be given in the modern factory with its complicated machinery which must be used in a fixed way. Thus while freedom of choice may be important, there is usually very little that can be done to create it. Another important consideration is how much each worker contributes to the product he is making. In most factories the worker sees only one small part of the product. Some car factories are now experimenting with having many small production lines rather than one large one, so that each worker contributes more to the production of the cars on his line. It would seem that not only is degree of worker contribution an important factor, therefore, but it is also one we can do something about. To what extent does more money lead to greater productivity? The workers themselves certainly think this important. But perhaps they want more money only because the work they do is so boring. Money just lets them enjoy their spare time more. A similar argument may explain demands for shorter working hours. Perhaps if we succeed in making their jobs more interesting, they will neither want more money, nor will shorter working hours be so important to them.1. Which of these possible factors leading to greater productivity is not true? ______
