单选题 {{B}}The Pentagon(五角大楼){{/B}} The Pentagon, headquarters of the Department of Defence in US, is one of the world's largest office buildings. It is twice the size of the Merchandise Mart in Chicago, and has three times the floor space of the Empire State Building in New York. There are very few people throughout the United States who do not have some knowledge of the Pentagon. Many have followed news stories emanating from the defence establishment housed in this building. However, relatively few people have had the opportunity to visit. The Pentagon is virtually a city in itself. Approximately 23,000 employees, both military and civilian, contribute to the planning and execution of the defence of the country. These people arrive daily from Washington, D.C. and its suburbs over approx imately 30 miles of access highways, including express bus lanes and one of the newest subway systems in the country. They ride past 200 acres of lawn to park approximately 8,770 cars in 16 parking lots; climb 131 stairways or ride 19 escalators to reach offices that occupy 3,705 square feet. While in the building, they tell time by 4,200 clocks, drink from 691 water fountains, utilize 284 rest rooms, consume 4,500 cups of coffee, 1,700 pints of milk and 6,800 soft drinks prepared or served by a restaurant staff of 230 persons and distributed in 1 dining room, 2 cafeterias, 6 snack bars, and an outdoor snack bar. The restaurant service is a privately run civilian operation under contract to the Pentagon. Stripped of its occupants, furniture and various decorations, the building alone in an extraordinary structure. Built during the early years of World War Ⅱ, it is still thought of as one of the most efficient office buildings in the world. Despite 17.5 miles of corridors it takes only seven minutes to walk between any two points in the building.

单选题 {{B}}Young people and their parents{{/B}} It is natural for young people to be critical of their, parents at times and to blame them for most of the misunderstandings between them. They have always complained, more or less justly, that their parents are out of touch with modern ways; that they are possessive and dominant; that they do not trust their children to deal with crisis; that they talk too much about certain problems—and that they have no sense of humor, at least in parent-child relationships. I think it is true that parents often underestimate their teenage children and also forget how they themselves felt when young. Young people often irritate their parents with their choices in clothes and hairstyles, in entertainers and music. This is not their motive. They feel cut off from the adult world into which they have not yet been accepted. So they create a culture and society of their own. Then, it turns out that their music or entertainers or vocabulary or clothes or hairstyles irritate their parents. This gives them additional enjoyment. They feel they are superior, at least in small way, and that they are leaders in style and taste. Sometimes you are resistant, and proud because you do not want your parents to approve of what you do. If they did approve, it looks as if you are betraying your own age group. But in that case, you are assuming that you are underdog: you can't win but at least you can keep your honor. This is a passive way of looking at things. It is natural enough after long years of childhood, when you were completely under your parents' control. But it ignores the fact that you are now beginning to be responsible for yourself. If you plan to control your life, co-operation can be part of that plan. You can charm others, especially your parents, into doing things the way you want. You can impress others with your sense of responsibility and initiative, so that they will give you the authority to do what you want to do.

单选题Dreams Everyone can dream. Indeed, everyone does dream. Those who 1 that they never dream at all actually dream 2 as frequently as the rest of us, 3 they may not remember anything about it. Even those of us who are perfectly 4 of dreaming night 5 night very seldom remember those dreams in 6 detail but merely retain an untidy mixture of seemingly unrelated impressions. Dreams are not simply visual—we dream with all our 7 , so that we appear to experience sound, touch, smell, and taste. One of the world"s oldest 8 written documents is the Egyptian Book of Dreams. This volume is about five thousand years old, so you can 9 that dreams were believed to have a special significance even then. Many ancient civilizations believed that you 10 never ask a sleeping person as, during sleep, the soul had left the body and might not be able to return 11 time if the sleeper were suddenly 12 . From ancient times to the present 13 , people have been 14 attempts to interpret dreams and to explain their significance. There are many books available on the subject of dream interpretation, although unfortunately there are almost as many meanings for a particular dream 15 there are books.

单选题Why is the Native Language Learnt So Well How does it happen that children learn their mother tongue so well? When we compare them with adults learning a foreign language, we often find this interesting fact. A little child without knowledge or experience often succeeds in a complete mastery(精通) of the language. A grown-up person with fully developed mental powers, in most case, may end up with a faulty and inexact command(掌握). What accounts for this difference? Despite other explanations, the real answer in my opinion lies partly in the child himself, partly in the behavior of the people around him. In the first place, the time of learning the mother tongue is the most favorable of all, namely, the first years of life. A child hears it spoken from morning till night and, what is more important, always in its genuine form, with the right pronunciation, right intonation, right use of words and right structure. He drinks in(吸引) all the words and expressions, which come to him in a flash, ever-bubbling(冒泡的) spring. There is no resistance: there is perfect assimilation. Then the child has, as it were, private lessons all the year round, while an adult language-student has each week a limited number of hours, which he generally shares with others. The child has another advantage : he hears the language in all possible situations, always accompanied by the right kind of gestures and facial expressions. Here there is nothing unnatural, such as it is often found in language lessons in schools, when one talks about ice and snow in June or scorching heat in January. And what a child hears is generally what immediately interests him. Again and again, when his attempts at speech are successful, his desires are understood and fulfilled. Finally, though a child's "teachers" may not have been trained in language teaching, their relations with him are always close and personal. They take great pains to make their lessons easy.

单选题Immigration and Problems Hundreds of thousands of people supporting immigration rights in the US filled streets all over America in early 2006. Many held signs and American flags and asked to be treated as citizens-not criminals. Many of these supported legislation from Senator John McCain that would open a path to citizenship to immigrants who were already in the country illegally. Proposed legislation from other politicians called for stricter measures-including rounding up undocumented immigrants and sending them back to their home countries. Canadian officials say that immigration applications continue to rise. Some want to keep the doors open. They need the labor. About 400,000 immigrants were allowed into the country in 2005, according to the Canadian Government statistics. However, all this growth means that cities need to adapt. New comers don't always make a smooth transition into jobs for which they are skilled. So industries are using mentoring (辅导) programs to help new immigrants find proper jobs. With the large numbers of undocumented African immigrants arriving in the Canary Islands and showing no sign of abating (减少), the Spanish Government has decided to get tough. There will be no more mass amnesties (特赦) for illegals, and anyone coming to Spain without permission will be sent back, the government has announced. About 23,000 migrants landed on the islands in 2006, and riots have erupted in some crowded reception centers. This has promoted local authorities to appeal to the United Nations for help. France's new immigration and integration law gives the government new powers to encourage high-skilled migration. It takes effect in 2007. The new law authorizes the government will help these identified employers find immigrant workers with needed skills or qualifications. The selected foreign employees will be granted "skills and talents" visas valid for three years. But some people show the concern that it'll cause brain drain in developing countries.

单选题Meals away from home What makes Americans spend nearly half their food dollars on meals away from home? The answers lie in the way Americans live today. During the first few decades of the twentieth century, canned and other convenience foods freed the family cook from full-time duty at the kitchen range. Then, in the 1940s, work in the wartime defense plants took more women out of the home that ever before, setting the pattern of the working wife and mother. Unless family members pitch in with food preparation, women are not fully liberated from that chore. It's easier to pick up a bucket of fried chicken on the way home from work or take the family out for pizzas or burgers than to start opening cans or heating up frozen dinners after a long, hard day. Also nowadays, the rising divorce rate means that there are more single working parents with children to feed. And many young adults and elderly people, as well as unmarried and divorced mature people, live alone rather than as a part of a family unit and don't want to bother cooking for one. Fast food is appealing because it is fast, it doesn't require any dressing up, it offers a "fun" break in the daily routine, and the outlay of money seems small. It can be eaten in the car, sometimes picked up at a drive-in window without even getting out, or on the run. Even if it is brought home to eat, there will never be any dirty dishes to wash because of the handy disposable wrappings. Children, especially, love fast food because it's finger food, no struggling with knives and forks, no annoying instructions from adults about table manners.
