单选题War is the social cancer of mankind. It is a pernicious form of ignorance, for it destroys not only its "enemies", but also the whole superstructure of what it is a part—and thus eventually it defeats itself.

单选题 Attacking an increasingly popular Internet business practice, a consumer watchdog group Monday filed a complaint with the Federal Trade Commission, asserting that many online search engines are concealing the impact special fees have on search results by Internet users. Commercial Alert, a 3-year-old group founded by consumer activist Ralph Na-der, asked the FTC to investigate whether eight of the Web's largest search engines are violating federal laws against deceptive advertising. The group said that the search engines are abandoning objective formulas to determine the order of their listed results and selling the top spots to the highest bidders without making adequate disclosures to Web surfers. The complaint touches a hot-button issue affecting tens of millions of people who submit search queries each day. With more than 2billion pages and more than 14 billion hyperlinks on the Web, search requests rank as the second most popular online activity after E-mail. The eight search engines named in Commercial Alert's complaint are: MSN, owned by Microsoft; Netscape, owned by AOL Time Warner; Directhit, owned by Ask Jeeves;HotBot and Lycos, both owned by Term Lycos; AltaVista, owned by CMGI; LookSmart,owned by KookSmart; and iWon, owned by a privately held company operating under the same name. Portland, Ore-based Commercial Alert could have named more search engines in its complaint, but focused on the biggest sites that are auctioning off spots in their results,said Gary Ruskin, the group's executive director. "Search engines have become central in the quest for learning and knowledge in our society. The ability to skew (扭曲) the results in favor of hucksters (小贩) without telling consumers is a serious problem. " Ruskin said. By late Monday afternoon, three of the search engines had responded to The Associated Press' inquiries about the complaint.Two, LookSmart and AltaVista, denied the charges. Microsoft spokesman Matt Pilla said MSN is delivering "compelling search results that people want". The FTC had no comment about the complaint Monday. The complaint takes aim at the new business plans embraced by more search engines as they try to cash in on their pivotal (关键) role as Web guides and reverses a steady stream of losses. To boost revenue,search engines in the past year have been accepting payments from businesses interested in receiving a higher ranking in certain categories or ensuring that their sites are reviewed more frequently.

单选题Modern American music is rich in its variety of forms, styles, and instruments. A complete encyclopedia (百科全书) of American music is a small library! By just looking at a few types of American music, we can see much diversity. Blues music, which goes back to the 1860s, has African American roots. Blues singers often sing of sad themes: feelings of loneliness or hunger, or being far away from home. The banjo and the washboard were common instruments in early blues music. The harmonica, guitar, and piano are some of the many other instruments used in blues. Jazz has its beginnings in the 1890s in New Orleans. The musical contributions of people from many parts of the world came together in this port on the Mississippi River to create the early versions of jazz. Now jazz comes in many forms and is popular in the United States and many other countries. The fiddle is a common instrument in early country music, but today we hear many kinds of instruments in country music, especially the guitar. Cowboy movies in the 1930s and 1940s helped to make country music very popular. Rap music has its origins in New York in the early 1970s. Rap uses a lot of rhyming. Rhymes are words that sound the same. Many young people like the beat in rap music. Like all music, modern American music causes people to sing, dance, smile, and cry. American music is sometimes controversial (有争议的), but it shows us the diversity of American culture.

单选题Ideas about education are changing in the United States. Education today is not just a high school diploma or a college degree. Many adults are not interested in going to college. They are interested in other kinds of learning. For them, learning does not end with a diploma． Continuing education gives these adults the opportunity to increase their knowledge about their own field or to learn about a new field．It also gives them a chance to improve their old skills or to learn new ones. Scientists, mechanics and barbers can take classes to improve their work skills. If they know more or learn more, they can get a better job or earn more money. Continuing education classes give more adults the chances to learn new skills. There is usually a large variety of classes to choose from: typing, foreign cooking, photography, auto repair, furniture repair, or swimming. These are only some of the classes available. Some adults take classes for fun or because the class will be useful for them. Other adults take continuing education classes to improve their own lives because they want to feel better about themselves. Almost any community college or public school system has a continuing education program. There are classes in schools, community buildings or churches. Most classes are in the evening, so working people can attend．The classes are usually small, and they are inexpensive.

单选题You ask how to start a business? Here is an example. David Dawson, a serious mountain climber, was dissatisfied with soft iron pitons (锥锤), the only ones he was able to buy. They lasted just one or two climbs, and Dawson wanted to replace them with "chrome-molys" (铬率合金), which were harder, stronger and longer-lasting. Some climbers made them for limited distribution among friends, but they were not commercially available. So Dawson started Dawson Equipment Ltd. , a purveyor (承办商) of climbing equipment, as a one-man enterprise in Burbank, California, in 1958. He had no plan, no management experience and no advertising. He worked in a shed using a hand forge purchased with $ 800 of capital borrowed from his mother. What Dawson did have was a knowledge of the kind of equipment that he needed in his own climbs, and a sense that serious climbers would follow his lead. Currently Dawson Equipment is thriving and produces over 200 products. Business opportunities are mere than ample today for the simple reason that many consumers are dissatisfied. Dawson's business started from his being a customer not liking what he bought. I suspect that your business will begin that way too. You know what you want to replace, improve or change. So begin where the tool breaks, the service slips or the shoe pinches.

单选题The most surprising aspect of the modern man's good conscience is that he asserts and justifies it in terms of the most varied and even contradictory metaphysical theories and social philosophies. The idealist Hegel and the materialist Marx agree in their fundamental confidence in human virtue, disagreeing only in their conception of the period and the social circumstances in which and the method by which his essential goodness is, or is to be, realized. The romantic naturalist Rousseau agrees with the rationalistic naturalists of the French Enlightenment, though in the one case the seat of virtue is found in natural impulse unspoiled by rational disciplines and in the other case it is reason which guarantees virtue. Among the rationalistic naturalists again there is agreement upon this point whether they are hedonistic or Stoic in their conceptions and whether they believe that reason discovers and leads to a natural harmony of egoistic impulses or that it discovers and affirms a natural harmony of social impulses. The whole Christian drama of salvation is rejected ostensibly because of the incredible character of the myths of Creation, Fall, Atonement, etc., in which it is expressed. But the typical modern is actually more certain of the complete irrelevance of these doctrines than of their incredibility. He is naturally not inclined to take dubious religious myths seriously, since he finds no relation between the ethos which informs them and his own sense of security and complacency. The sense of guilt expressed in them is to him a mere vestigial remnant of primitive fears of higher powers, of which he is happily emancipated. The sense of sin is, in the phrase of a particularly vapid modern social scientist, "a psychopathic aspect of adolescent mentality". The universality of this easy conscience among moderns is the more surprising since it continues to express itself almost as unqualifiedly in a period of social decay as in the eighteenth- and nineteenth-century heyday of a bourgeois culture. The modern man is involved in social chaos and political anarchy. The Marxist escape from this chaos has developed in Russia into a regime of unparalleled proportions. Contemporary history is filled with manifestations of man's hysteria and furies; with evidences of his demonic capacity and inclination to break the harmonies of nature and defy the prudent canons of rational restraint. Yet no cumulation of contradictory evidence seems to disturb modern man's good opinion of himself. He considers himself the victim of corrupting institutions which he is about to destroy or reconstruct, or of the confusions of ignorance which an adequate education is about to overcome. Yet he continues to regard himself as essentially harmless and virtuous. The question therefore arises how modern man arrived at, and by what means he maintains, an estimate of his virtue in such pathetic contradiction with the obvious facts of his history.

单选题Everyone is exposed to it, so naturally some people will imitate what they see on TV, what they read in the newspapers and what they witness every day. It is better to prevent violence than to try to stop it. Dentists tell you to brush your teeth to prevent cavities so they won"t have to fill the cavity later. People and lawmakers all over the world realize this. The next question is, "How do you prevent violence from happening?" To answer this question, you may ask yourself, "What causes violence?" Guns are definitely something used in acts of violence, but just about anything will do. Bare hands are often the weapons. What we have to do is to work together as a community and make violence wrong but not to tolerate. We"ve got to find a better solution than jails, and we"ve got to do it now. It"s not something that can wait. The message "Violence is wrong" has got to be everywhere you look on TV, on street signs, buses, radio, in every kind of language—English, Spanish, French, Hebrew, you name it, so that it can reach all kinds of people. People need to be cool. Violence needs to be labeled as foolish. It cannot be machismo (大男子气概) and toughness. We can reach people in all kinds of ways. Little reminders that "Violence is wrong" can show up in any way, shape or form: chain letters, a million dollars to anyone who can make a video showing 30 acts of kindness, flyers, newspaper ads, contests in schools, a free TV ad to the most peace-loving company and much more. To do so, lots of people have to be willing to work together and break the cycle.

单选题What really works to make sustainable changes in diet and lifestyle? It"s probably not what you think. Years of clinical research proves that the real keys are pleasure, joy and freedom, not our power of will or austerity (苦行). Joy of living is sustainable; fear of dying is not. Why? Because life is to be enjoyed. There"s no point in giving up something you enjoy unless you get something back that"s even better, and quickly. When people eat more healthfully, exercise, quit smoking, manage stress better, and love more, they find that they feel so much better, so quickly, it reconstruct the reason for making these changes from fear of dying to joy of living. Fortunately, the latest studies show how dynamic and powerful are the mechanisms that control our health and well-being. When you exercise and eat right: Your brain receives more blood flow and oxygen, so you become smarter, think more clearly, have more energy, and need less sleep. Two studies showed that just walking for three hours per week for only three months caused so many new nerve cells to grow that it actually increased the size of people"s brains! Your face receives more blood flow, so your skin glows more and wrinkles less. You look younger and more attractive. In contrast, an unhealthy diet, lasting emotional stress and smoking reduce blood flow to your face so you age more quickly. Smoking accelerate aging because nicotine (尼古丁) causes your blood vessel to become narrower, which decreases blood flow to your face and makes it wrinkle prematurely. This is why smokers look years older than they really are. One of the most interesting findings in this study was that the mothers" perceptions of stress were more important than what was objectively occurring in their lives. The researchers made a survey among women and asked them to rate on a three-point scale how stressed they felt each day, and how out of control their lives felt to them. The women who perceived that they were under heavy stress had significantly shortened and damaged telomeres (染色体端粒) compared with those who felt more relaxed. Conversely, some of the women who felt relaxed despite raising a disabled child had more normal-appearing telomeres. In other words, if you feel stressed, you are stressed.
