单选题Schooling and Education It is commonly believed in the United States that school is where people go to get an education. Nevertheless, it has been said that today children interrupt their education to go to school. The distinction between schooling and education implied by this remark is important. Education is much more open-ended and all-inclusive than schooling. Education knows no limits. It can take place anywhere, whether in the shower or in the job, whether in a kitchen or in a theatre. It includes both the formal learning that takes place in schools and the whole universe of informal learning. The agents of education can range from a respected grandparent to the people debating politics on the radio, from a child to a distinguished scientist. Whereas schooling has a certain predictability, education quite often produces surprises. A chance conversation with a stranger may lead a person to discover how little is known of other religions. People are engaged in education from infancy (婴儿期) on. Education, then, is a very broad, inclusive term. It is a lifelong (一生的) process, a process that starts long before the start of school, and one that should be an integral (基本的) part of one's entire life. Schooling, on the other hand, is a specific, formalized process, whose general pattern varies little from one setting to the next. Throughout a country, children arrive at school at approximately the same time, take assigned (指定的) seats, are taught by an adult, use similar textbooks, do homework, take exams and so on. The slices of reality that are to be learned, whether they are words or an understanding of the working of government, have usually been limited by the boundaries of the subject being taught. For example, high school students know that they are not likely to find out in their classes the truth about political problems in their communities or what the newest filmmakers are experimenting with. There are definite conditions surrounding the formalized process of schooling.

单选题New U.S. Plan for Disease Prevention Urging Americans to take responsibility for their health, Health and Human Services Secretary Tommy Thompson on Tuesday launched a $15 million program to try to encourage communities to do more to prevent chronic diseases like heart disease, cancer and diabetes. The initiative highlights the cost of chronic diseases—the leading causes of death in the United States——and outlines ways that people can prevent them, including better diet and increased exercise. "In the United States today, 7 of 10 deaths and the vast majority of serious illness, disability and health care costs are caused by chronic diseases," the Health and Human Services Department said in a statement. The causes are often behavioral——smoking, poor eating habits and a lack of exercise. "I am convinced that preventing disease by promoting better health is a smart policy choice for our future," Thompson told a conference held to launch the initiative. "Our current health care system is not structured to deal with the escalating costs of treating diseases that are largely preventable through changes in our lifestyle choices." Thompson said heart disease and strokes will cost the country more than $351 billion in 2003. "These leading causes of death for men and women are largely preventable, yet we as a nation are not taking the steps necessary for US to lead healthier, longer lives," he said. The $15 million is slated to go to communities to promote prevention, pushing for changes as simple as building sidewalks to encourage people to walk more. Daily exercise such as walking can prevent and even reverse heart disease and diabetes, arid prevent cancer and strokes. The money will also go to community organizations, clinics and nutritionists who are being encouraged to work together to educate people at risk of diabetes about what they can do to prevent it and encourage more cancer screening. The American Cancer Society estimates that half of all cancers can be caught by screening, including Pap tests for cervical cancer, mammograms for breast cancer, colonoscopies, and prostate checks. If such cancers were all caught by early screening, the group estimates that the survival rate for cancer would rise to 95 percent.

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 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).
