单选题Many Americans harbor a grossly distorted and exaggerated view of most of the risks surrounding food. Fergus Clydescale, head of the department of food science and nutrition at the University of Massachusetts-Amherst, says bluntly that if the dangers from bacterially contaminated chickens were as great as some people believe, "the streets would be littered with people lying here and there." Though the public increasingly demand no-risk food, there is no such thing. Bruce Ames, chairman of the Biochemistry Department at the University of California, Berkley, points out that up to 10% of a plant"s weight is made up of natural pesticides. He says, "Since plants do not have jaws or teeth to protect themselves, they employ chemical warfare." And many naturally produced chemicals, though occurring in tiny amounts, prove in laboratory tests to be strong carcinogens—a substance which causes cancer. Mushrooms might be banned if they were judged by the same standards that apply to food additives. Christina Stark, a nutritionist at Cornell University, says, "We"ve got far worse natural chemicals in the food supply than anything man-made." Yet the issues are not simple. While Americans have no reason to be terrified to sit down at the dinner table, they have every reason to demand significant improvements in food and water safety. They unconsciously and unwillingly take in too much of too many dangerous chemicals. If food already contains natural carcinogens, it does not make much sense to add dozens of new man-made ones. Though most people will withstand the small amounts of contaminants generally found in food and water, at least a few individuals will probably get cancer one day because of what they eat and drink. To make good food and water supplies even better, the Government needs to tighten its regulatory standards, stiffen its inspection program and strengthen its enforcement policies. The food industry should modify some long-accepted practices or turn to less hazardous alternatives. Perhaps most important, consumers will have to do a better job of learning how to handle and cook food properly. The problems that need to be tackled exist all along the food supply chain, from fields to processing plants to kitchens.

单选题Since 1960, the fast-growing town of Hotstone, Arizona, has drawn water from the Gray River, which feeds Lake Mudfish.

单选题 Last weekend Kyle MacDonald in Montreal threw a party to celebrate the fact that he got his new home in exchange for a red paper clip. Starting a year ago, MacDonald bartered the clip for increasingly valuable stuff, including a camp stove and free rent in a Phoenix flat. Having announced his aim (the house) in advance, MacDonald likely got a boost from techies eager to see the Internet pass this daring test of its networking power. "My whole motto (座右铭) was 'Start small, think big, and have fun', "says MacDonald, 26, "I really kept my effort on the creative side rather than the business side." Yet as odd as the MacDonald exchange was, barter is now big business on the Net. This year more than 400000 companies worldwide will exchange some $10 billion worth of goods and services on a growing number of barter sites. These Web sites allow companies to trade products for a virtual currency, which they can use to buy goods from other members. In Iceland, garment- maker Kapusalan sells a third of its output on the booming Vidskiptanetid exchange, earning virtual money that it uses to buy machinery and pay part of employee salaries. The Troc-Services exchange in France offers more than 4600 services, from math lessons to ironing. This is not a primitive barter system. By creating currencies, the Internet removes a major barrier—what Bob Meyer, publisher of BarterNews, calls "the double coincidence of wants." That is, two parties once not only had to find each other, but also an exchange of goods that both desired. Now, they can price the deal in virtual currency. Barter also helps firms make use of idle capacity. For example, advertising is "hugely bartered" because many media, particularly on the Web, can supply new ad space at little cost. Moreover, Internet ads don't register in industry-growth statistics, because many exchanges are arranged outside the formal exchanges. Like eBay, most barter sites allow members to "grade" trading partners for honesty, quality and so on. Barter exchanges can allow firms in countries with hyperinflation or nontradable currencies to enter global trades. Next year, a nonprofit exchange called Quick Lift Two (QL2) plans to open in Nairobi, offering barter deals to 38000 Kenyan farmers in remote areas. Two small planes will deliver the goods. QL2 director Gacii Waciuma says the farmers are excited to be "liberated from corrupt middlemen." For them, barter evokes a bright future, not a precapitalist past.

单选题Most people would be 1 by the high quality of medicine 2 to most Americans. There is a lot of specialization, a great deal of 3 to the individual, a 4 amount of advanced technical equipment, and 5 effort not to make mistakes because of the financial risk which doctors and hospitals must 6 in the courts if they 7 things badly. But the Americans are in a mess. The problem is the way in 8 health care is organized and 9 . 10 to public belief it is not just a free competition system.

The basic problem, however, is that there is no central control 15 the health system. There is no 16 to what doctors and hospitals charge for their services, other than what the public is able to pay. The number of doctors has shot up and prices have climbed. When faced with toothache, a sick child, or a heart attack, all the unfortunate person concerned can do is 17 up. Two thirds of the population 18 covered by medical insurance. Doctors charge as much as they want 19 that the insurance company will pay the bill. The rising cost of medicine in the U. S. A is among the most worrying problems facing the country. In 1981 the country"s health bill climbed 15.9 per cent—about twice as fast as price 20 general.
