单选题Ford"s Assembly Line When it comes to singling out those who have made a difference in all our lives, you cannot overlook Henry Ford. A historian a century from now might well conclude that it was Ford who most influenced all manufacturing, everywhere, even to this day, by introducing a new way to make cars—one, strange to say, that originated in slaughterhouses (屠宰场). Back in the early 1900s, slaughterhouses used what could have been called a "disassembly line". Ford reversed this process to see if it would speed up production of a part of an automobile engine called a magneto (磁力发电机). Rather than have each worker completely assemble a magneto, one of its elements was placed on a conveyer, and each worker, as it passed, added another component to it, the same one each time. Professor David Hounshell of the University of Delaware, an expert on industrial development, tells what happened. "The previous day, workers carrying out the entire process averaged one assembly every 20 minutes. But on that day, on the line, the assembly team averaged one every 13 minutes and 10 seconds per person." Within a year, the time had been reduced to five minutes. In 1913, Ford went all the way. Hooked together by ropes, partially assembled vehicles were towed (拖, 拉) past workers who completed them one piece at a time. It wasn"t long before Ford was turning out several hundred thousand cars a year, a remarkable achievement then. And so efficient and economical was this new system that he cut the price of his cars in half, to $260, putting them within reach of all those who, up until that time, could not afford them. Soon, auto makers all over the world copied him. In fact, he encouraged them to do so by writing a book about all of his innovations, entitled Today and Tomorrow. The Age of the Automobile had arrived. Today, aided by robots and other forms of automation, everything from toasters to perfumes is made on assembly lines.

单选题 Crystal Ear One day a friend asked my wife Jill if I wanted a hearing aid "He certainly does." replied Jill. After hearing about a remarkable new product, Jill finally got up the nerve to ask me if I'd ever thought about getting a hearing aid. "No way," I said. "It would make me look 20 years older." "No, no," she replied. "This is entirely different. It's Crystal Ear!" Jill was right. Crystal Ear is different—not the old-styled body worn or over-the-ear aid, but all advanced personal sound system so small that it's like contacts (隐形眼镜) for your ears. And Crystal Ear is super-sensitive and powerful, too. You will hear sounds your ears have been missing for years. Crystal Ear will make speech louder, and the sound is pure add natural. I couldn't believe how tiny it is. It is smaller than the tip of my little finger and it's almost invisible when worn. There are no wires, no behind-the-ear device. Put it in your ear and its ready-to-wear mold(形状) fits comfortably. Since it's not too loud or too tight, you may even forget that you're wearing it! Use it at work or at play. And if your hearing problem is worse in certain situations, use Crystal Ear only when you need it. Hearing loss, which occurs typically prior to teenage years, progresses throughout one's lifetime. Although hearing loss is now the world's number one health problem, nearly 90 percent of people suffering hearing loss choose to leave the problem untreated. For many millions, treating hearing loss in a conventional way can involve numerous office visits, expensive testing and adjustments to fit your ear. Thanks to Crystal Ear, the "sound solution" is now convenient. Almost 90 percent of people with mild hearing loss, and millions more with just a little hearing drop-off (下降), can be dramatically helped with Crystal Ear. More over, its superior design is energy-efficient, so batteries can last months. Crystal Ear is now available to help these people treat their hearing loss with a small hearing amplifier (放大器).

单选题Electronic Teaching The potential of closed-circuit television and other new electronic teaching tools is so great that it is fascinating to visualize "the school of tomorrow" Televised lessons will originate from a central building having perhaps four or five master studios. The lessons will be carried into classrooms all over a city, or even an entire country. After a televised lesson has been given, the classroom teacher will take over for the all-important "follow-up" period. The students will ask any troublesome questions, and difficult points will be cleared up through discussion. The teacher in the classroom will have additional electronic tools. On the teacher's desk, the traditional chalk and erasers will have been replaced by a multiple-control panel and magnetic tape player. The tape machines will run pre-recorded lessons which pupils will follow by headphones. The lessons will be specifically geared to the students' levels of ability. For instance, while the class as a whole studies history, each student will receive an individual history lesson, directed to his particular level of ability. Should question arise, the students will be able to talk directly to the teacher on individual "intercoms" without disturbing the rest of the class. In this way, the teacher will be able to conduct as many as three classes at the same time. With the rapid development of computer science, students will be aided with specially prepared multimedia software to study their subjects better. Homework will possibly be assigned and handed in via electronic mail system. Students can even take examinations on their computer linked with the teacher's and get the score instantly. They will get certificates or diplomas if they pass all the required examinations. Experts believe that this type of education will be very popular in the years ahead.

单选题第一篇 Losing Weight Girls as young as 10 years old are dieting and in danger of developing unhealthy attitudes about weight, body image and food, a group of Toronto researchers reported Tuesday. Their study of 2,279 girls aged 10 to 14 showed that while the vast majority had healthy weights, nearly a third felt they were overweight and were trying to lose pounds. Even at the trader age of 10, nearly 39. per cent of girls felt "too fat" and 31 percent said they were trying to diet. McVey, a researcher at the Hospital for Sick Children in Toronto, and her colleagues analyzed data collected in a number of surveys of southern Ontario school girls between 1993 and 2003, reporting their findings in Tuesday"s issue of the Canadian Medical Association Journal. Nearly 80 percent of the girls had a healthy body weight and only 7.2 per cent were considered overweight using standard weight-to height ratios. Most researchers suggest the rate of overweight children in this country is several times higher than that figure. Nearly 30 percent of the girls reported they were currently trying to lose weight, though few admitted to dangerous behavior such as self-induced vomiting. Still, a test that measured attitudes towards eating showed 10.5 per cent of survey participants were already at risk of developing an eating disorder. "We"re not talking about kids who"ve been prescribed a diet because they"re above average weight or overweight. We"re talking about children who are within a healthy weight range. And they have taken it upon themselves to diet to lose weight, "McVey said, acknowledging she found the rates disturbing. She said striking a balance between healthy weights and healthy attitudes towards food and body image is a complex task, with no easy solutions.

单选题 阅读下面这篇短文，短文后列出?个句子，请根据短文的内容对每个句子做出判断。 {{B}} Vocational Education{{/B}} Vocational education refers to education for a particular occupation. Industrialized countries have seen a fall in demand for unskilled workers, and an increase in jobs in the professional, technical, commercial, and administrative sector. Vocational education is traditionally associated with trades and crafts: young people were apprentice to employers for a number of years and learned on the job. Today the focus has shifted from the workplace to secondary and higher education institutions, and from employers' to government provision and finance. Trainees in most occupations combine workplace training with study at a technical or academic institution. In the former Soviet Union, school and work were always strongly linked from primary school. Germany provides nine out of ten young people not entering higher education with vocational training, and training is planned from national down to locate level through joint committees of government representatives, employers, and trade unions. In some countries, skills are being grouped and "job families" created so that individuals can move between jobs with similar technical requirements. In others "competency-based education" is advocated to equip individuals with "transferable" as well as specific skills. In developing countries, where it is traditional for children to work from an early age, only a tiny proportion of students follow a formal vocational program, while the long specialist training of professionals such as doctors, lawyers, and engineers is a costly burden. Training places for technicians, nurses, teachers, and the essential workers are often limited. Worldwide, there is a slow but steady increase in the numbers of women training for occupations of influence in science, technology, law, and business. It is also becoming clear that one course of vocational education is not enough for a life time. Retraining, through continuing education is essential.

单选题A Great Quake Coming? Everyone who lives in San Francisco knows that earthquakes are common in the Bay Area--and they can be devastating．In 1906，for example，a major quake destroyed about 28,000 buildings and killed hundreds，perhaps thousands of people．Residents now wonder when the next“Big One”will strike．It's bound to happen someday．At least seven active fault(断层)lines run through the San Francisco area． Faults are places where pieces of Earth's crust(地壳)slide past each other．When these pieces slip，the ground shakes． To prepare for that day，scientists are using new techniques to reanalyze the 1906 earthquake and predict how bad the damage might be when the next one happens． One new finding about the 1906 quake is that the San Andreas fault split apart faster than scientists had assumed at the time．During small earthquakes，faults rupture(断裂)at about 2.7 kilometers per second．During bigger quakes，however．ruptures can happen at rates faster than 3.5 kilometers per second． At such high speeds，massive amounts of pressure build up，generating underground waves that can cause more damage than the quake itself．Lucky for San Francisco，these pressure pulses(脉冲)traveled away from the city during the 1906 event．As bad as the damage was，it could have been far worse． Looking ahead．scientists are trying to predict when the next major quake will occur．Records show that earthquakes were common before 1906．Since then，the area has been relatively quiet．Patterns in the data，however，suggest that the probability of a major earthquake striking the Bay Area before 2032 is at least 62 percent． New buildings in San Francisco are quite safe in case of future quakes．Still，more than 84 percent of the city's buildings are old and weak．Analyses suggest that another massive earthquake would cause extensive damage． People who live there today tend to feel safe because San Francisco has remained pretty quiet for a while．According to the new research，however．it's not a matter of“if”the Big One will hit．It's just a matter of when．

单选题Stress Level Tied to Education Level People with less education suffer fewer stressful days, according to a report in the current issue of the Journal of Health and Social Behavior. However, the study also found that when less-educated people did suffer stress it was more severe and had a larger impact on their health. From this, researchers have concluded that the day-to-day factors that cause stress are not random. Where you are in society determines the kinds of problems that you have each day, and how well you will cope with them. The research team interviewed a national sample of 1,031 adults daily for eight days about their stress level and health. People without a high school diploma reported stress on 30 percent of the study days, people with a high school degree reported stress 38 percent of the time, and people with college degrees reported stress 44 percent of the time. "Less advantaged people are less healthy on a daily basis and are more likely to have downward turns in their health," lead researcher Dr. Joseph Grzywacz, of Wake Forest University Baptist Medical Center, said in a prepared statement. "The downward turns in health were connected with daily stressors and the effect of daily stressors on their health is much more devastating for the less advantaged." Grzywacz suggested follow-up research to determine why less-educated people report fewer days of stress when it is known their stress is more acute and chronic. "If something happens every day, maybe it"s not seen as a stressor," Grzywacz says. "Maybe it is just life."

单选题Moral Issues One of the virtues in American culture is to help others. Christmas in America means different things to different people. To some people, Christmas means brightly wrapped packages under a decorated tree. To others, it means family reunions and a wonderful meal together. Christmas also means lending a helping hand to people in need. Along with all the hubbub of shopping for presents and sending Christmas cards, many people in America take time to help others. In America and around the world, Christmas offers many opportunities to spread "Peace on earth, good will toward men". For example, Salvation Army bell ringers are a familiar sight to most Christmas shoppers. They stand outside malls and stores collecting money for the needy. Many churches and other organizations collect toys and clothes as Christmas gifts for poor families. The Christmas spirit encourages people to help each other in many large and small ways. The spirit of helping others isn't limited to Christmas. However, Americans help others year-round. Civic clubs such as the Lion's Club, the Elk's Club and the Rotary Club take part in local community projects. Many organizations exist just to help others. The Make a Wish Foundation gives terminally ill children a chance to have their dream come true. Habitat for Humanity helps poor people build their own houses. And besides supporting worthy causes with their money, thousands of Americans donate their time by serving as volunteers in hospitals, homeless shelters and schools. Another virtue Americans respect is perseverance. Remember Aesop's fable about the turtle and the rabbit that had a race? The rabbit thought he could win easily, so he took a nap. But the turtle finally won because he did not give up. Compassion may be the queen of American virtues. The story of "The Good Samaritan" from the Bible describes a man who showed compassion. On his way to a certain city, a Samaritan man found a poor traveler lying on the road. The traveler had been beaten and robbed. The kind Samaritan, instead of just passing by, stopped to help this person in need. Compassion can even turn into a positive cycle. In fall, 1992, people in Iowa sent truckloads of water to help Floridians hit by a hurricane. The next summer, during the Midwest flooding, Florida returned the favor. In less dramatic ways, millions of Americans are quietly passing along the kindness shown them. In no way can this brief description cover all the moral values honored by Americans. Courage, responsibility, loyalty, gratitude and many others could be discussed. In fact, Bennett's best-seller over 800 pages highlights just l0 virtues. Even Bennett admits that he has only scratched the surface. But no matter how long or short the list is, moral values are invaluable. They are the foundation of American culture and any culture.
