单选题In the 1960s the West Coast became an important center for rock music. Los Angeles and Southern California are famous for sunshine and surfing. There, a quieter kind of rock called surf rock became famous. The Beach Boys sang songs like "Surfin"U.S.A.", "California Girls" and "Fun, Fun, Fun". These songs made people dream about the good life in California. San Francisco was a center for young people and rock music in the late 1960s. This was the time of the Vietnam War, student protest, hippies, and drugs. Hippies talked about love and peace. They wore brightly colored clothes and had long hair. They listened to rock and folk-rock music. Drugs were a serious problem during that time. The deaths of three young rock stars, Janis Jopling, Jim Morrison and the great guitar player Jimi Hendrix were all related to drugs. Not all of the rock musicians came from California or the U.S.A. That was the time of the great British rock groups like the Beatles and the Rolling Stones. British rock musicians had a very important place in the rock music of the 1960s in America. Another kind of softer rock music was created by the singers. Singers like Joni Mitchell and James Taylor wrote their own lyrics and their own music. Their songs were about love and friendship, good and bad times. In the 1960s big rock concerts were very welcomed by everyone. The most famous concert was Woodstock. In 1969 in New York State, a million young people came together to hear the rock stars. This peaceful Woodstock concert was the most important musical event of the 1960s. After World War Ⅱ a great number of black people moved from the South to the big industrial cities like New York, Detroit, and Philadelphia. Many black people lived in poor parts of the city such as Harlem in New York. Musicians wrote and sang about life in the big cities. Life was difficult but music and dancing made it a little easier. Popular black music had a strong beat for dancing. At first this music was called rhythm and blues. The 1960s called it soul. In Detroit, a black musician named Berry Gordy set up an all black record company. It was called Motown. Motown or motor town is another name for Detroit, where cars are made. Most of the famous soul musicians like the Supremes, the Temptations, and the Jackson Five recorded with Motown.

单选题Clothes play a critical part in the conclusions we reach by providing clues to who people are, who they are not, and who they would like to be. They tell us a good deal about the wearer's background, personality, status, mood, and social outlook. Since clothes are such an important source of social information, we can use them to manipulate people's impression to us. Our appearance assumes particular significance in the initial phases of interaction that is likely to occur. An elderly middle-class man or woman may be alienated by a young adult who is dressed in an unconventional manner, regardless of the person's education, background, or interests. People tend to agree on what certain types of clothes mean. Adolescent girls can easily agree on the life- styles of girls who wear certain outfits, including the number of boyfriends they likely have had and whether they smoke or drink. Newscasters, or the announcers who read the news on TV, are considered to be more convincing, honest, and competent when they are dressed conservatively. And college students who view themselves as taking an active role in their interpersonal relationships say they are concerned about the costumes they must wear to play these roles successfully. Moreover, many of us can relate instances in which the clothing we wore changed the way we felt about ourselves and how we acted. Perhaps you have used clothing to gain confidence when you anticipated a stressful situation, such as a job interview, or a court appearance. In the workplace, men have long had well-defined precedents and role models for achieving success. It has been otherwise for women. A good many women in the business world are uncertain about the appropriate mixture of "masculine" and "feminine" attributes they should convey by their professional clothing. The variety of clothing alternative to women has also been greater than that available for men. Male administrators tend to judge women more favorable for managerial positions when the women display less "feminine" grooming — shorter hair, moderate use of make-up, and plain tailored clothing. As one male administrator confessed, "An attractive woman is definitely going to get a longer interview, but she won't get a job. /

单选题{{B}}Text 4{{/B}} As one of the biggest restaurants in the world, McDonald's origination and development has been a miracle in this field. The McDonald's story began in 1954 in San Bernardino, California. At first, the restaurant is run by two brothers, Dick and Mac McDonald. It didn't go very well at first; at one time it was nearly closed. However, the two brothers insisted on and overcame the difficulties, and made it turn for the better day by day. Ray Kroc, a milk shake machine salesman, saw the massive potential of the brothers' business and decided to get involved. He purchased the rights from the brothers, on April 15th, 1955. He became the McDonald brothers' first franchisee when he opened his own McDonald's restaurant in Des Plaines, a suburb just north of Chicago. The entry of Ray Kroc into the business contributed to the development in the history of McDonald's. He bought the rights to expand the McDonald's concept outside of California and Arizona, and quickly built the restaurant chain and by 1959 over 100 restaurants were in operation. What is the secret of Ray Kroc? As a matter of fact, the restaurant was a favor for many of the Iocal teens at first and the menu was primarily barbeque items. Eight years later, the restaurant was closed for several months as it was renovated to become a restaurant that served food and was easy to prepare and served quickly. The food was very limited including Hamburgers, French fries and cold drinks. The employees prided themselves on creating an assembly line type of food preparation and being speedy in getting their food to the customers. The very basic step paved the path to glory. It separated McDonald's from the rest of the competitors and attributes to their great success. The restaurant proved to be an instant success. By 1984, McDonald's served 17 million customers a day that was equivalent to serving lunch to the entire population of Australia and New Zealand. Today, McDonald's becomes one of the most famous and successful "fast food" chain in America and the world. McDonald's restaurants are now located in 31,000 locations all over the world, and the company employs more than 1.5 million people. Just have a look at its development in UK. In September 2004 the UK company owned restaurants employed 43,491 people: 40,699 hourly-paid restaurant employees, 2,292 restaurant managers, and 500 office staff. McDonald's franchisees employed a further 25,000 people.

单选题American humor and American popular heroes were born together. The first popular heroes of the new nation were comic heroes, and the first popular humor of the new nation was the antics of its hero-clowns. The heroic and the comic were combined in novel American proportions in popular literature. The heroic themes are obvious enough and not much different from those in the legends of other times and places: Achilles, Beowulf, Siegfried, Roland, and King Arthur. The American Davy Crockett legends repeat the familiar pattern of the old world heroic story: the pre-eminence of a mighty hero whose fame in myth has a tenuous basis in fact; the remarkable birth and precocious strength of the hero; single combats in which he distinguished himself against antagonists, both man and beast; vows and boasts; pride of the hero in his weapons, his dog, and his woman. Davy Crockett conquered man and beast with a swaggering nonchalance. He overcame animals by force of body and will. He killed four wolves at the age of six. He hugged a bear to death; he killed a rattlesnake with his teeth. He mastered the forces of nature. Crockett's most famous natural exploit was saving the earth on the coldest day in history. First, he climbed a mountain to determine the trouble. Then he rescued all creation by squeezing bear-grease on the earth's frozen axis and over the sun's icy face. He whistled, "push along, keep moving!" The earth gave a grunt and began moving. Neither the fearlessness nor the bold huntsman's prowess was peculiarly American. Far more distinctive was the comic quality, all heroes are heroic; few are also clowns. What made the American popular hero heroic also made him comic. Maybe, said Crockett, you'll laugh at me, and not at my book. The ambiguity of American life and the vagueness which laid the continent open to adventure, which made the land a rich storehouse of the unexpected, which kept vocabulary ungoverned and the language fluid—this same ambiguity suffused both the Crockett legends were never quite certain whether to laugh or to applaud, or whether what they saw and heard was wonderful, awful, or ridiculous.

单选题{{B}}Text 2{{/B}} America's love affair with the credit card began in 1949. When businessman Frank McNamara finished a meal in a New York restaurant and then discovered he had no cash. In those days, gasoline and store charge cards were common, but cash was standard for almost everything else. McNamara called his wife, who rushed over to bail him out. His embarrassment gave him the idea for Diners Club. Within a year some 200 people carried the world's first multi-use card. For an annual fee of $5, these card holders could charge meals at 27 restaurants in and around New York City. By the end of 1951 more than a million dollars had been charged on the growing number of cards, and the company was soon turning a profit. The problem was to persuade enough people to carry the cards. Diners Club turned to promotions. It gave away a round-the-world trip on a popular television show. The winners charged their expenses and made it "from New York to New York without a dime in their pocket". By 1955 the convenience of charging was catching on in a big way. The first to turn a profit was Bank of America's Bank Americard. Bankers from all over the country descended on its California headquarters to learn the secret of its success—so many that in 1966 Bank Americard began forming alliances with banks outside the state. Five million holiday credit card shoppers would have created a bonanza for banks, but in the dash to market, the banks had been less than cautious in assembling their lists. Some families received 15 cards. Dead people and babies got cards. Hundreds of Chicagoans discovered they could use or sell a card they "found" and by law, the person whose name appeared on it was liable for the charges—even if he or she had never requested of received the card. The disaster sparked a movement to regulate the industry. Public Law 91-508, signed by President Nixon in October 1970, prohibited issuers from sending cards to people who hadn't requested them at all but eliminated card-holder liability for charges on a card reported lost or stolen. Later, the Fair Credit Billing Act set standard procedures for resolving billing disputes. Of course, Credit cards have not only replaced cash for many purposes, but also in effect have created cash by making it instantly available virtually everywhere. Experts estimate there are from 15,000 to 19,000 different cards available in his country. So the revolution that began in 1949 with an embarrassed businessman who was out of cash now seems complete. What Alfred Bloomingdale, then president of Diners Club, predicted more than 30 years ago seems to have come true: an America where "there will be only two classes of people—those with credit and those who can't get them."

单选题The use of the term "subjects" in the selection refers to

单选题 The U．S．Supreme Court has forbidden prayers in public schools，but many Americans cling to the idea that their educational system has a moral purpose．It is an idea common to both the Greeks and the medieval Church．In today’s world， the moral purpose of education takes non-religious forms，racial integration，sex education，good citizenship．At the college level，the ambiguities become more complex．Should a morally objectionable person be allowed to teach？Should a morally objectionable doctrine be permitted？ Many people are understandably dismayed by such inspection．But would they prefer moral neutrality？Should engineers be trained to build highways without being taught any concern for the homes they displace？Should prospective corporate managers learn how to increase profits regardless of pollution or unemployment？Just the opposite，according to Beyond the Ivory Tower，a new book by Harvard’s Bok，which calls for increased emphasis on“applied ethics”．(Writes Bok．“A university that refuses to take moral dilemmas seriously violates its basic obligations to society．”) Religious colleges have always practiced a similar preaching．But some 500 schools now offer courses in the field．The Government supports such studies with a program known as EVIST，which stands for Ethics and Values in Science and Technology (and which sounds as though a computer had already taken charge of the matter)．“The modern university is rooted in the scientific method，having essentially turned its back on religion，”says Steven Muller，president of John Hopkins．“The scientific method is a marvelous means of inquiry，but it really doesn’t provide a value system．The biggest failing in higher education today is that we fall short in exposing students to values．” Charles Muscatine，a professor of English at Berkeley and member of a committee that is analyzing liberal arts curriculums for the Association of American Colleges，is even harsher．He calls today’s education programs“a marvelous convenience for low-quality society．”The key goal of education，says Muscatine，should be“informed decision making that recognizes there is a moral component to life．”Instead，he says，most universities are“spreading the dangerous myth that technical skills are more important than moral reasoning．”

单选题For some people, it may be better ______.

单选题One important aspect of retirement for most people is deciding where to live. In the past, this was not an issue because most elderly persons remained at home where they could be close to family. In contemporary times, parents and grown children go their separate ways, staying in touch through the telephone and, more recently, through e-mail. Every year, more than 400,000 adults who are 55 or older move out of their home state and relocate. Florida leads all states in the proportion of elderly people-19 percent over 65 years of age, most of whom relocated from other places. Thus, Florida cities have become known as retirement centers. Among those prominently mentioned are Boca Raton, Daytona Beach, Fort Lauderdale, Fort Myers, Naples, and Ocala where between 20 and 25 percent of the residents is over 65 years of age. Two other Florida cities, Saint Petersburg and Sarasota, have even higher proportions-25 percent and 32 percent respectively. Other cities that have gained reputations as retirement centers with large number of elderly are Savannah, Georgia, Prescott and Scottsdale, Arizona, Palm Springs, California, and Asheville, North Carolina. Even tourist centers like Las Vegas and Reno, Nevada, where residents pay no income tax and no inheritance or estate taxes, are attracting growing numbers of seniors. There are also many smaller private development communities that are-packaged as state-of-the-art retirement communities with such amenities as golf courses, lakes for fishing and boating, cultural and recreation activities. They go by such names as Sun City Grand near Phoenix, Arizona, Sun City Palm Desert near Palm Springs California, Sun City Summerland near Las Vegas, Nevada, and Ford's Colony close to Williamsburg, Virginia among others. To the extent that the proportion of retired elderly people in towns and regions continues to grow, certain consequences tend to follow. Where such communities are essentially residential, their revenue base depends largely on the individual wealth of their residents. For this reason, the economies of such communities are becoming increasingly dependent on the rise and fall of pensions, Social Security, and Medicare payments. Retirees are also likely to block future industrial development efforts since their priorities emphasize nice climate and attractive places to live and recreate. They are inclined to reject the noise and congestion that comes with new factories and the jobs they bring to the economy.

单选题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 says. 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 says 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 executives 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 age, 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 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 headhunter. "The people who've been hurt the worst are those who've stayed too long. /
