单选题The Family The structure of a family takes different forms around the word and even in the same society. The family"s form changes as it adapts to changing social and economic influences. Until recently, the most common form in North America was the nuclear family, consisting of a married couple with their minor children. The nuclear family is an independent unit. It must be prepared to fend for itself. Individual family members strongly depend on one another. There is little help from outside the family in emergencies. Elderly relatives of a nuclear family are cared for only if it is possible for the family to do so. In North America, the elderly often do not live with the family; they live in retirement communities and nursing homes. There are many parallels between the nuclear family in industrial societies, such as North America, and of families in societies such as that of the Inuits, who live in harsh environments. The nuclear family structure is well adapted to a life of mobility. In harsh conditions, mobility allows the family to hunt for food. For North Americans, the hunt for jobs and improved social status also requires mobility. The nuclear family was not always the North American standard. In a more agrarian time, the small nuclear family was usually part of a larger extended family. This might have included grandparents, mother and father, brothers and sisters, uncles, aunts, and cousins. In North America today, there is a dramatic rise in the number of single-parent households. Twice as many households in the United States are headed by divorced, separated, or never-married individuals as are comprised of nuclear families. The structure of the family, not just in North America, but throughout the world, continues to change as it adapts to changing conditions.

单选题Eating Meat--Less or More? Every second in the United States alone, more than 250 animals are slaughtered for food, adding up to more than 8 billion animals each year. Reducing the amount of meat in one's diet is nutritionally, environmentally, and ethically beneficial. People who eat meat usually have weaker immune systems compared to those of vegetarians. Meat has been directly linked to diabetes, obesity, arthritis, and many other illnesses. Furthermore, meat-eaters are at a higher risk for diseases, including cancer, and they are more likely to die from these diseases. Critics say that a meatless diet does not provide enough nutrients, especially protein and iron. Actually, according to A Teen's Guide to Going Vegetarian, by Judy Krizmanic, protein is found in almost every food, and iron appears in many vegetables. Getting enough nutrients in a meat-reduced diet should not be difficult. A 1988study found that some of the highest pesticide residues appear in meat and eggs. Diets including more fruits and vegetables will only make people healthier. Some skeptics believe that there will he a shortage of food if animals are not eaten. In fact, the opposite is true. More than 80% of the corn and 95% of the oats grown in the U. S. are fed to livestock. The world's cattle alone consume enough food to equal the caloric needs of 8.7 billion people, more than the entire human population. One half of the water used in the Unites States also goes to livestock； 2,50 gallons of water produces only 1 lb. of beef. If people eat less meat and more plants, the amount of available food will increase. Many people become vegetarians because they feel that eating animals is unethical. 90 of these animals are raised in confinement. Chickens and other birds have only about half a square foot of space each, and since they are raised so close together, a lot blade is used to cut off their beaks to prevent them from pecking each other to death. Likewise, pigs that are repressed will bite each other's tails, so both their teeth and tails are removed as soon as they are born. Eating animals is hazardous in numerous ways. Even a slight reduction in meat intake is better than nothing at all. Consuming less meat is beneficial to the health of animals, the health of people, and to the health of the world.

单选题{{B}}第三篇{{/B}} {{B}} Generation Gap{{/B}} A few years ago, it was fashionable to speak of a generation gap, a division between young people and their elders. Parents complained that children did not show them proper respect and obedience, while children complained that their parents did not understand them at all. What had gone wrong? Why had the generation gap suddenly appeared? Actually, the generation gap has been around for a long time. Many critics argue that it is built into the fabric of our society. One important cause of the generation gap is the opportunity that young people have to choose their own life styles. In more traditional societies, when children grow up, they are expected to live in the same area as their parents, to marry people that their parents know and approve of, and often to continue the family occupation. In our society, young people often travel great distances for their education, most out of the family home at an early age, marry or live or choose occupations different from those of their parents. In our upwardly mobile society, parents often expect their Children to do better than they did: to find better jobs, to make more money, and to do all the things that they were unable to do. Often, however, the ambitions that parents have for their children are another cause of the division between them. Often they discover that they have very little in common with each other. Finally, the speed at which changes take place in our society is another cause of the gap between the generations. In a traditional culture, elderly people are valued for their wisdom, but in our society the knowledge of a lifetime may become obsolete overnight. The young and the old seem to live in two very different worlds, separated by different skills and abilities. No doubt, the generation gap will continue to be a feature of American life for some time to come. Its causes are rooted in the freedoms and opportunities of our society, and in the rapid pace at which society changes.

单选题Importance of Services The United States has moved beyond the industrial economy stage to the point where it has become the world's first service economy. Almost three fourths of the non-farm labor force is employed in service industries, and over two-thirds of the nation's gross national product is accounted for by services. Also, service jobs typically hold up better during a recession than do jobs in industries producing tangible goods. During the 20-year period of 1966 to 1986, about 36 million new jobs were created in the United States — far more than in Japan and Western Europe combined. About 90 per cent of these jobs were in service industries. During this same time span, some 22 million women joined the labor force — and 97 per cent of these women went to work in the service sector. These employment trends are expected to continue at least until the year 2000. For the period 1986—2000, the Bureau of Labor Statistics predicts that over 21 million new jobs will be created and 93 per cent of them will be in service industries. Moreover, most of this explosive growth in services employment is not in low — paying jobs, contrary to the beliefs of many economists, business and labor leaders, and politicians. These people argue that manufacturing jobs, which have been the economic foundation of America's middle class, are vanishing. They claim that factory workers are being replaced with a host of low-wage earners. It is true that manufacturing jobs have declined, with many of them going to foreign countries. It is also true that there has been growth in some low-paying service jobs. Yet cooks and counter people still represent only 1 per cent of the US labor force today. Furthermore, for many years the fastest-growing occupational category has been "professional, technical, and related work." These jobs pay well above the average, and most are in service industries. About one-half of consumer expenditures are for the purchase of services. Projections to the year 2000 indicate that services will attract all even larger share of consumer spending. A drawback of the service economy boom is that the prices of most services have been going up at a considerably faster rate than the prices of most tangible products. You are undoubtedly aware of this if you have had your car or TV set repaired, had your shoes half-soled, or paid a medical bill in recent years. When we say that services account for close to one-half of consumer expenditures, we still grossly understate the economic importance of services. These figures do not include the vast amounts spent for business services. By all indications, spending for business services has increased even more rapidly than spending for consumer services. gross national product 国民生产总值, 略作 GNP tangible goods 有形商品 drawback n. 缺点; 不利条件

单选题How the Body Keeps the Same Temperature The temperature of your body should be always just the same, no matter whether the weather is trot or cold. That is why the doctor uses his thermometer when you are sick. When you are well,your temperature is ninety-eight and six tenths degrees. If he finds it (51) than that,it is a sure sign that something is wrong. The body keeps the same temperature all the time,because it balances (平衡) the heat it produces and (52) off. It is always burning up food and producing heat. It can produce heat faster when it needs to or give off heat faster when it becomes too warm. Let's see (53) this happens. The heat of your body is given off chiefly through the skin. When you are (54) ,your skin is tight and shows "goose flesh". When you get chilly (寒冷的),you must dance around to keep warm or (55) you will shiver (颤抖). (56) your muscles begin to work,burn up fuel,and produce more heat. It is not (57) to shiver,so you usually prefer warming up by exercise, or put (58) more clothes to keep heat in. When you are warm,the skin is loose and soft. It is so supplied (59) blood that heat is given off rapidly. If you get too hot,you begin to sweat,and (60) body heat is used in evaporating (蒸发) the moisture (潮湿) from your skin. You wear less clothing, too, in warm (61) or in a warm room,so that warmth can be given off freely. You feel you don't (62) exercising because your body is warm (63) ,and the extra heat produced by exercise makes you uncomfortable. You can see from this why you (64) differently in different kinds of weather. In summer,when it is warm,you feel tired and lazy. You do not care to work or play,but enjoy lying and doing nothing.

单选题One-room Schools One-room schools are part of the heritage of the United States, and the mention of them makes people feel a vague long for the way things were. One-room schools are an endangered species. However, for more than a hundred years, one-room schools have been systematically shut down and their students sent away to centralized schools. As recently as 1930, there were 149,000 one-room schools in the United States. By 1970 there were 1,800. Today, of nearly 800 remaining one-room schools more than 350 are in Nebraska. The rest are scattered through a few other states that have on their road maps wide-open spaces between towns. Now that there are hardly any left, educators are beginning to think that maybe there is something yet to be learned from one-room schools, something that served the pioneers that might serve as well today. Progressive educators have come up with progressive-sounding names like "peer-group teaching" and "multi-age grouping" for educational procedures that occur naturally in the one-room schools. In a one-room school the children teach each other because the teacher is busy part of the time teaching someone else. A fourth grader can work at a fifth-grade level in math and a third-grade level in English without the stigma associated with being left back or the pressures of being skipped ahead. A youngster with a learning disability can find his or her own level without being separated from the other pupils. In larger urban and suburban schools today this is called mainstreaming. A few hours in a small school that has only one classroom and it becomes clear why so many parents feel that one of the advantages of living in Nebraska is that their children have to go to a one-room school.

单选题Find Better Jobs When Liam McGee departed as president of Bank of America in August, his explanation was surprisingly straight up. Rather than cloaking his exit in the usual vague excuses, he came right out and said he was leaving "to pursue my goal of running a company." Broadcasting his ambition was "very much my decision," McGee said. Within two weeks, he was talking for the first time with the board of Hartford Financial Services Group, which named him CEO and chairman on September 29. McGee said leaving without a position lined up gave him time to reflect on what kind of company he wanted to run. It also sent a clear message to the outside world about his aspirations. And McGee isn"t alone. In recent weeks the No. 2 executive at Avon and American Express quit with the explanation that they were looking for a CEO post. As boards scrutinize succession plans in response to shareholder pressure, executives who don"t get the nod also may wish to move on. A turbulent business environment also has senior managers cautious of letting vague pronouncements cloud their reputations. As the first signs of recovery begin to take hold, deputy chiefs may be more willing to make the jump without a net. In the third quarter, CEO turnover was down 23% from a year ago as nervous boards stuck with the leaders they had, according to Liberum Research. As the economy picks up, opportunities will abound for aspiring leaders. The decision to quit a senior position to look for a better one is unconventional. For years executives and headhunters have adhered to the rule that the most attractive CEO candidates are the ones who must be poached. Says Korn Ferry, senior partner Dennis Carey: "I can"t think of a single search I"ve done where a board has not instructed me to look at sitting CEOs first." Those who jumped without a job haven"t always landed in top positions quickly. Ellen Marram quit as chief of Tropicana a decade ago, saying she wanted to be a CEO. It was a year before she became head of a tiny internet-based commodities exchange. Robert Willumstad left Citigroup in 2005 with ambitions to be a CEO. He finally took that post at a major financial institution three years later. Many recruiters say the old disgrace is fading for top performers. The financial crisis has made it more acceptable to be between jobs or to leave a bad one. "The traditional rule was it"s safer to stay where you are, but that"s been fundamentally inverted," says one head-hunter. "The people who"ve been hurt the worst are those who"ve stayed too long."

单选题{{B}}第三篇{{/B}} {{B}} More Than a Ride to School{{/B}} The National Education Association claims, "The school bus is a mirror of the community." They further add that, unfortunately, what appears on the exterior (外部) does not always reflect the reality of a chosen community. They are right, and sometimes it reflects more! Just ask Liesl Denson. Riding the school bus has been more than a ride to school for Liesl. Bruce Hardy, school bus driver for Althouse Bus Company has been Liesl's bus driver since kindergarten. Last year when Liesl's family moved to Parkesburg, knowing her bus went by her new residence, she requested to ride the same bus. This year Liesl is a senior and will enjoy her last year riding the bus. She says, "It's been a great ride so far! My bus driver is so cool and has always been a good friend and a good listener. Sometimes when you're a child adults do not think that what you have to say is important. Mr. Hardy always listens to what you have to say and makes you feel important." Her friends Ashley Batista and Amanda Wolfe agree. Bruce Hardy has been making Octorara students feel special since 1975. This year he will celebrate 30 years working for Althouse Bus Transportation. Company President, Larry Althouse acknowledges Bruce Hardy's outstanding record. "You do not come by employees like Bruce these days; he has never missed a day of work and has a perfect driving record. Recognized in 2000 by the Pennsylvania School Bus Association for driving 350,000 accident free miles, Hardy's reputation is made further evident through the relationships he has made with the students that ride his bus." Althouse further added, "Althouse Bus Transportation was established 70 years ago and has been providing quality transportation ever since. My grandfather started the business with one bus. Althouse Bus Transportation is delighted to have the opportunity to bring distinctive and safe service to our local school and community and looks forward to continuing to provide quality service for many more years to come." Three generations of business is not all the company has enjoyed. Thanks to drivers like Bruce Hardy, they have been building relationships through generations. Liesl's mother Carol also enjoys fond memories of riding Bruce Hardy's bus to the Octorara School District.
