Human needs seem endless. When a hungry man gets a meal, he begins to think about an overcoat: when a manager gets a new sports car, a big house and pleasure boats dance into view. The many needs of mankind might be regarded as making up several levels. When there is money enough to satisfy one level of needs, another level appears. The first and most basic level of needs involves food. Once this level is satisfied, the second level of needs, clothing and some sort of shelter, appears. By the end of World War II, these needs were satisfied for a great majority of Americans. Then a third level appeared. It included such items as automobiles and new houses. By 1957 or 1958 this third level of needs was fairly well satisfied. Then, in the late 1950s, a fourth level of needs appeared: the "life-enriching" level. While the other levels involve physical satisfaction, that is, the feeding, comfort, safety, and transportation, this level stresses mental needs for recognition, achievement, and happiness. It includes a variety of goods and services, many of which could be called "luxury" items. Among them are vacation trips, the best medical and dental care, and recreation. Also included here are fancy goods and the latest styles in clothing. On the fourth level, a lot of money is spent on services, while on the first three levels more is spent on goods. Will consumers raise their sights to a fifth level of needs as their income increases, or will they continue to demand luxuries and personal services on the fourth level? A fifth level would probably involve needs that can be achieved best by community action. Consumers may be spending more on taxes to pay for government action against disease, ignorance, crime, and prejudice. After filling our stomachs, our clothes closets, our garages, our teeth, and our minds, we now may seek to ensure the health, safety, and leisure to enjoy more fully the good things on the first four levels.

The United States【C1】______a large part of the North American continent. Its neighbors are Canada【C2】______the north, and Mexico to the south.【C3】______the United States is a big country, it's not the largest in the world, In 1964 its population was over 185, 000, 000. When this land first became a nation, after winning independence from England, it had thirteen states, 【C4】______of the states was represented on the American flag by a star All the states were in the eastern part of the continent. As the nation grew towards the west, new states were in the eastern part of the continent. As the nation grew towards the west, new states were added and new stars appeared on the flag. For a long time, there were 48 states. In 1959, however, two【C5】______stars were added to the flag【C6】______the new states【C7】______Alaska and Hawaii. Sometimesit is said that the Indians are the only real Americans. Most Americans, however, are descendants(后代)of people who came from all over the world to find a new life in a new land. Those who came first and【C8】______greatest numbers to make their home【C9】______the eastern coast of North America were mostly from England. It is【C10】______that reason that the language of the United States is English and that its culture and customs are more like those of England than of any other country in the world.

Car accidents kill more than one million people and injure approximately 50 million each year.【C1】______, millions of fish can swim together in a school with【C2】______no collisions. How do fish do it, and what can they teach us about how to reduce car【C3】______? Schooling fish learn about their surroundings through their eyesand a special sense【C4】______called the side line. They use these senses to【C5】______the location of other fish around them, and they follow their own rules. Firstly, they always travel side by side. They match the speed of the fish beside them and maintain their distance from them. Secondly, they always draw nearer to fish that are farther away from them. Thirdly, they have their own way【C6】______collisions by changing directions to avoid contact with other fish. 【C7】______those three behaviors of schooling fish, a car manufacturer designed several tiny robot cars that can travel in a group without colliding.【C8】______eyes, the robots use communication technologies: instead of a side line, they use a laser range finder. The company believes that this technology will help them to create " collision-free" cars and "contribute to an environmentally-【C9】______and traffic-jam-free driving environment." " We recreated the behavior of a school of fish by【C10】______latest electronic technologies, " says the principal engineer of the robot-car project. " We, in a motorized world, have a lot to learn from the behavior of a school of fish."

One day, science says a glass of red wine a day will help us live longer.

We have heard a lot about the health benefits of tea, especially green tea. It is high in polyphenols, compounds with strong antioxidant activity that in test-tube and animal models show anticancer and heart-protective effects. Good clinical studies are few, however, and although physicians tell their patients to drink green tea, there hasn't been any definite proof of the value of that advice. A team of Japanese researchers was able to link green tea consumption with decreased mortality from many causes-including heart disease. The researchers tracked 40,530 healthy adults ages 40 to 79 in a region of northeastern Japan where most people drink green tea, following them for up to 11 years. Those who drank five or more cups of green tea a day had significantly lower mortality rates than those who drank less than one cup a day. There were also fewer deaths from cardiovascular disease. But no such association was seen with deaths from cancer. Nor was consumption of oolong or black tea connected with any decrease in mortality. Those teas are easier to be combined with oxygen in processing, which not only darkens the color of the leaves and changes their flavor but also reduces their polyphenol content. Coffee is more complicated. It has received both gold stars and black marks in medical literature. It, too, contains antioxidants, although they are less well studied than tea polyphenols. Evidence for the health benefits of coffee is growing, however. A group of investigators from Finland, Italy and the Netherlands reports that coffee seems to protect against age-related decline in mental capacity. The scientists studied 676 healthy men born from 1900 to 1920 and followed them for 10 years, using standardized measures of brain function. Their conclusion: the men who consumed coffee had significantly less decline in mental capacity than those who didn't. Three cups a day seemed to provide the most protection. Population studies like those help us form assumptions about relationships between dietary habits and long-term health. We still have to test our suppositions in controlled conditions, and measure the effects of coffee and tea on various systems of the body.
