单选题Persons who are overweight should watch their diet carefully in order to lose pounds. The best way to do this is to start a weight control program. At first it is wise to talk with your doctor. He can advise you of the number of calories (卡路里) you should have in your meals each day. He can tell you about exercising while on your diet. A good rule is to lose slowly. A loss of a pound or two is plenty. Plan meals around foods you know. This means that it is wise to include foods that you are used to and that are part of your regular eating habits. When you have lost the weight you wish, simple items can be added to your diet so that you can maintain the weight you want. While you are dieting, try to build a pattern of eating that you can follow later to maintain your desired weight. When dieting, choose low-calorie foods. Avoid such items as fats, fried food, sweets, cakes, cream and soft drinks. Try to take coffee and tea without sugar or cream. Snacks can be part of your diet. For example, a piece of fruit or a simple dessert saved from mealtime can be eaten between meals. Keep busy! This way you will not be tempted to go off the diet. Make full use of opportunities to exercise. Try walking instead of riding whenever possible. Happy dieting!

单选题We have known for a long time that the organization of any particular society is influenced by the definition of the sexes and the distinction drawn between them. But we have realized only recently that the identity of each sex is not so easy to pin down, and that definitions evolve in accordance with different types of culture known to us, that is, scientific discoveries and ideological revolutions. Our nature is not considered as immutable, either socially or biologically. As we approach the beginning of the 21st century, the substantial progress made in biology and genetics is radically challenging the roles, responsibilities and specific characteristics attributed to each sex, and yet, scarcely twenty years ago, these were thought to be "beyond dispute". We can safely say, with a few minor exceptions, that the definition of the sexes and their respective functions remained unchanged in the West from the beginning of the 19tb century to the 1960s. The role distinction, raised in some cases to the status of uncompromising dualism on a strongly hierarchical model, lasted throughout this period, appealing for its justification to nature, religion and customs alleged to have existed since the dawn of time. The woman bore children and took care of the home. The man set out tc conquer the world and was responsible for the survival of his family, by satisfying their needs in peacetime and going to war when necessary. The entire world order rested on the divergence of the sexes. Any overlapping or confusion between the roles was seen as a threat to the time-honored order of things. It was felt to be against nature, a deviation from the norm. Sex roles were determined according to the "place" appropriate to each. Women's place was, first and foremost, in the home. The outside world, i.e. workshops, factories and business firms, belonged to men. This sex-based division of the world (private and public) gave rise to a strict dichotomy between the attitudes, which conferred on each its special identity. The woman, sequestered at home, "cared, nurtured and conserved". To do this, she had no need to be daring, ambitious, tough or competitive. The man, on the other hand, competing with his fellow men, was caught up every day in the struggle for survival, and hence developed those characteristics which were thought natural in a man. Today, many women go out to work, and their reasons for doing so have changed considerably. Besides, the traditional financial incentives, we find ambition and personal fulfillment motivating those in the most favorable circumstances, and the wish to have a social life and to get out of their domestic isolation influencing others. Above all, for all women, work is invariably connected with the desire for independence.

单选题Come on, my fellow white folks, we have something to confess. Out with it, friends, the biggest secret known to whites since the invention of powdered rouge: welfare is a white program. The numbers go like this: 61% of the population receiving welfare, listed as "means-tested cash assistance" by the Census Bureau, is identified as white, while only 33% is identified as black. These numbers notwithstanding, the Republican version of "political correctness" has given us "welfare cheat" as a new term for African American since the early days of Ronald Reagan. Our confession surely stands: white folks have been gobbling up the welfare budget while blaming someone else. But it's worse than that. If we look at Social Security, which is another form of welfare, although it is often mistaken for an individual insurance program, then whites are the ones who are crowding the trough. We receive almost twice as much per capita, for an aggregate advantage to our race of $10 billion a year--much more than the $3. 9 billion advantage African American gain from their disproportionate share of welfare. One sad reason: whites live an average of six years longer than African Americans, meaning that young black workers help subsidize a huge and growing "over-class" of white retirees. I do not see our confession bringing much relief. There's a reason for resentment, though it has more to do with class than with race. White people are poor too, and in numbers far exceeding any of our more generously pigmented social groups. And poverty as defined by the government is a vast underestimation of the economic terror that persists at incomes--such as $ 20,000 or even $ 40,000 and above--that we like to think of as middle class. The problem is not that welfare is too generous to blacks but that social welfare in general is too stingy to all concerned. Naturally, whites in the swelling "near poor" category resent the notion of whole races supposedly frolicking at their expense. Whites, near poor and middle class, need help too--as do the many African Americans. So we white folks have a choice. We can keep pretending that welfare is black program and a scheme for transferring our earnings to the pockets of shiftless, dark-skinned people. Or we can clear our throats, blush prettily and admit that we are hurting too--for cash assistance when we're down and out, for health insurance, for college aid and all the rest. Racial scapegoating has its charms, I will admit: the surge of righteous anger, even the fun--for those inclined--of wearing sheets and burning crosses. But there are better, nobler sources of white pride, it seems to me. Remember this: only we can truly, deeply blush.

单选题While still in its early stages, welfare reform has already been judged a great success m many states at least in getting people off welfare. It's estimated that more than 2 million people have left the rolls since 1994. In the past four years, welfare rolls in Athens County have been cut in half. But 70 percent of the people who left in the past two years took jobs that paid less than $ 6 an hour. The result: The Athens County poverty rate still remains at more than 30 percent— twice the national average. For advocates (代言人) for the poor, that's an indication much more needs to be done. "More people are getting jobs, but it's not making their lives any better," says Kathy Lain, a policy analyst at the Center on Budget and Policy Priorities in Washington. A center analysis of US Census data nationwide found that between 1995 and 1996, a greater percentage of single, female headed households were earning money on their own, but that average income for these households actually went down. But for many, the fact that poor people are able to support themselves almost as well without government aid as they did with it is in itself a huge victory. "Welfare was a poison. It was a toxin(毒素) that was poisoning the family," says Robert Rector, a welfare reform policy analyst. "The reform is changing the moral climate in low-income communities. It's beginning to rebuild the work ethic (道德观), which is much more important. " Mr. Rector and others argued that once "the habit of dependency is cracked", then the country can make other policy changes aimed at improving living standards.

单选题Someone has calculated that by the time an American reaches the age of 40, he or she has been exposed to one million ads. Another estimate is that we have encountered more than 600, 000 ads by the time we reach the age of only 18. Now, of course, we don't remember what exactly they said or even what the product was, but a composite message gets through: that you deserve the best, that you should have it now, and that it's okay to indulge yourself, because you deserve the compliments, sex appeal, or adventure you are going to get as a result of buying this car or those cigarettes. Our consumer-based economy makes two absolutely reciprocal psychological demands on its members. On the one hand, you need the "discipline" values to ensure that people will be good workers and lead orderly, law-abiding lives. On the other hand, you need the "enjoy yourself" messages to get people to be good consumers. One author was disturbed about the "enjoy yourself" side, but acknowledged that "without a means of stimulating mass consumption, the very structure of our business enterprise would collapse." The interesting question has to do with the psychological consequences of the discrepancy between the dual messages. The "discipline" or "traditional values" theme demands that one compartment of the personality have a will strong enough to keep the individual doing unpleasant work at low wages, or to stay in an unhappy marriage, and, in general, to do things for the good of the commonwealth. The "enjoy yourself" message, on the other hand, tends to encourage a very different kind of personality-one that is self-centered, based on impulse, and is unwilling to delay rewards. As an illustration, I can't. resist reciting one of my favorite ads of all time, an ad from a psychology magazine: "I love me. I'm just a good friend to myself. And I like to do what makes me feel good. I used to sit around, putting things off till tomorrow. Tomorrow I'll drink champagne, and buy a set of pearls, and pick up that new stereo. But now I live my dreams today, not tomorrow." So what happens to us as we take in these opposing messages, as we are, in fact, torn between the opposite personality types that our society seems to require of us? Tile result is anxiety, fear, and a mysterious dread. The fear of being sucked in and dragged down by our consumer culture is real: the credit card company is not friendly when you default on your bills. And we all know that the path of pleasure-seeking and blind acquisition is a recipe for financial ruin-for most of us, anyway-and that, in American society, there isn't much of a safety net to catch you if you fall.

单选题 Every morning, kids from a local high school are working hard. They are making and selling special coffee at a coffee cafe. They are also making a lot of money. These students can make up to twelve hundred dollars a day. They are selling their special coffee to airplane passengers. After the students get paid, the rest of the money goes to helping a local youth project. These high school students use a space in the Oakland airport. It is usually very crowded. Many people who fly on the planes like to drink the special coffee. One customer thinks that the coffee costs a lot but it is good and worth it. Most customers are pleasant but some are unhappy. They do not like it if the cafe is not open for business. The students earn $6.10 an hour plus tips. They also get school credit whiel they learn how to run a business. Many of the students enjoy the work although it took some time to learn how to do it. They have to learn how to steam milk, load the pots, and add flavor. It takes some skill and sometimes mistakes are made. The most common mistake is forgetting to add the coffee.

单选题Prices determine how resources are to be used. They are also the means by which products and services that are in limited supply are rationed among buyers. The price system of the United States is a very complex network composed of the prices of all the products bought and sold in the economy as well as those of a myriad of services, including labor, professional, transportation, and public-utility services. The interrelationships of all these prices make up the "system" of prices. The price of any particular product or service is linked to a broad, complicated system of prices in which everything seems to depend more or less upon everything else. If one were to ask a group of randomly selected individuals to define "price", many would reply that price is an amount of money paid by the buyer to the seller of a product or service or, in other words, that price is the money value of a product or service as agreed upon in a market transaction. This definition is, of course, valid as far as it goes. For a complete understanding of a price in any particular transaction, much more than the amount of money involved must be known. Both the buyer anti the seller should be familiar with not only the money amount, but with the amount and quality of the product or service to be exchanged, the time and place at which the exchange will take place and payment will be made, the form of money to be used, the credit terms and discounts that apply to the transaction, guarantees on the product or service, delivery terms, return privileges, and other factors. In other words, both buyer and seller should be fully aware of all the factors that comprise the total "package" being exchanged for the asked-for amount of money in order that they may evaluate a given price.

单选题Richard Satava, program manager for advanced medical technologies, has been a driving force in bringing virtual reality to medicine, where computers create a "virtual" or simulated environment for surgeons and other medical practitioners. "With virtual reality we'll be able to put a surgeon in every trench," said Satava. He envisaged a time when soldiers who are wounded fighting overseas are put in mobile surgical units equipped with computers. The computers would transmit images of the soldiers to surgeons back in the U. S.. The surgeons would look at the soldiers through virtual reality helmets that contain a small screen displaying the image of the wound. The doctors would guide robotic instruments in the battlefield mobile surgical unit that operate on the soldier. Although Satava's vision may be years away from standard operating procedure, scientists are progressing toward virtual reality surgery. Engineers at an international organization in California are developing a tele-operating device. As surgeons watch a three-dimensional image of the surgery, they move instruments that are connected to a computer, which passes their movements to the robotic instruments that perform the surgery. The computer provides feedback to the surgeon on force, textures, and sound. These technological wonders may not yet be part of the community hospital setting but increasingly some of the machinery is finding its way into civilian medicine. At Wayne State University Medical School, surgeon Lucia Zamorano takes images of the brain from computerized scans and uses a computer program to produce a 3D image. She can then maneuver the 3D image on the computer screen to map the shortest, least invasive surgical path to the tumor. Zamorano is also using technology that attaches a probe to surgical instruments so that she can track their positions. While cutting away a tumor deep in the brain, she watches the movement of her surgical tools in a computer graphics image of the patient's brain taken before surgery. During these procedures—operations that are done through small cuts in the body in which a miniature camera and surgical tools are maneuvered—surgeons are wearing 3D glasses for a better view. And they are commanding robot surgeons to cut away tissues more accurately than human surgeons can. Satava says, "We are in the midst of a fundamental change in the field of medicine."

单选题Text 4 When we worry about who might be spying on our private lives, we usually think about the Federal agents. But the private sector outdoes the government every time. It's Linda Tripp, not the FBI, who is facing charges under Maryland's laws against secret telephone taping. It's our banks, not the Internal Revenue Service(IRS), that pass our private financial data to telemarketing firms. Consumer activists are pressing Congress for better privacy laws without much result so far. The legislators lean toward letting business people track our financial habits virtually at will. As an example of what's going on, consider U.S. Bancorp, which was recently sued for deceptive practices by the state of Minnesota. According to the lawsuit, the bank supplied a telemarketer called Member Works with sensitive customer data such as names, phone numbers, bank account and credit-card numbers, Social Security numbers, account balances and credit limits. With these customer lists in hand, Member Works started dialing for dollars—selling dental plans, videogames, computer software and other products and services. Customers who accepted a "free trial offer" had, 30 days to cancel. If the deadline passed, they were charged automatically through their bank or credit card accounts. U.S. Bancorp collected a share of the revenues. Customers were doubly deceived, the lawsuit claims. They didn't know that the bank was giving account numbers to Member Works. And if customers asked, they were led to think the answer was no. The state sued Member Works separately for deceptive selling. The company defends that it did anything wrong. For its part, U.S. Bancorp settled without admit ting any mistakes. But it agreed to stop exposing its customers to nonfinancial products sold by outside firms. A few top banks decided to do the same. Many other banks will still do business with Member Works and similar firms. And banks will still be mining data from your account in order to sell you financial products, including things of little value, such as credit insurance and credit card protection plans. You have almost no protection from businesses that use your personal accounts for profit. For example, no federal law shields "transaction and experience" information—mainly the details of your bank and credit card accounts. Social Security numbers are for sale by private firms. They've generally agreed not to sell to the public. But to businesses, the numbers are an open book. Self-regulation doesn't work. A firm might publish a privacy-protection policy, but who enforces it? Take U.S. Bancorp again. Customers were told, in writing, that "all personal information you supply to us will be considered confidential." Then it sold your data to Member Works. The bank even claims that it doesn't "sell" your data at all. It merely "shares" it and reaps a profit. Now you know.

单选题To Journalists, three of anything makes a trend. So after three school shootings in six days, speculation about an epidemic of violence in American classrooms was inevitable, and wrong. Violence in schools has fallen by half since the mid-1990s; children are more than 100 times more likely to be murdered outside the school walls than within them. On September 27th a 53-year-old petty criminal, Duane Morrison, walked into a school in Bailey, Colorado, with two guns. He took six girls hostage, molested some of them, and killed one before committing suicide as police stormed the room. And on September 29th a boy brought two guns into his school in Cazenovia, Wisconsin. Prosecutors say that 15-year-old Eric Hainstock may have planned to kill several people. But staff acted quickly when they saw him with a shotgun, calling the police and putting the school into "lock-down". The head teacher, who confronted him in a corridor, was the only one killed. October 2nd a 32-year-old milk-truck driver, Charles Roberts, entered a one-room Amish school in Nickel Mines, Pennsylvania. He lined the girls up, tied their feet and, after an hour, shot them, killing at least five. He killed himself as police broke into the classroom. What to make of such horrors? Some experts see the Colorado and Pennsylvania cases as an extreme manifestation of a culture of violence against women. Both killers appeared to have a sexual motive, and both let all the boys in the classroom go free. But it is hard to infer from such unusual examples, and one must note that violence against women is less than half what it was in 1995. Other experts see all three cases as symptomatic of a change in the way men commit suicide. Helen Smith, a forensic psychologist, told a radio audience "men are deciding to take their lives, "and they're not going alone anymore. They're taking people down with them." True, but not very often. Gun-control enthusiasts think school massacres show the need for tighter restrictions. It is too easy, they say, for criminals such as Mr. Morrison and juveniles such as Mr. Hainstock to obtain guns. Gun enthusiasts draw the opposite conclusion: that if more teachers carried concealed handguns, they could shoot potential child-killers before they kill. George Bush has now called for a conference on school violence. Will it unearth anything new, or valuable? After the Columbine massacre in 1999, the FBI produced a report on school shooters. It concluded that it was impossible to draw up a useful profile of a potential shooter because "a great many adolescents who will never commit violent acts will show some of the behaviours on any checklist of warning signs./
