单选题This week marks the 10th anniversary of the Alar apple scare, in which many American consumers were driven into a panic following the release of a report by an environmental organization claiming that apples containing the chemical Alar posed a serious health threat to preschoolers. The report was disseminated through a PR (Problem Report) campaign and bypassed any legitimate form of scientific peer review. Introduced to the American public by CBS "60 Minutes", the unsubstantiated claims in the report led some school districts to remove apples from their school lunch programs and unduly frightened conscientious parents trying to develop good eating habits for their children. Last month, Consumers Union released a report warning consumers of the perils of consuming many fruits and vegetables that frequently contained "unsafe" levels of pesticide residues. This was especially true for children, they claimed. Like its predecessor 10 years earlier, the Consumers Union report received no legitimate scientific peer review and the public's first exposure to it was through news coverage. Not only does such reporting potentially drive children for consuming healthful fruits and vegetables, the conclusions were based on a misleading interpretation of what constitutes a "safe" level of exposure. Briefly, the authors used values known as the "chronic reference doses", set by the U. S. environmental Protection Agency, as their barometers of safely. Used appropriately, these levels represent the maximum amount of pesticide that could be consumed daily for life without concern. For a 70-year lifetime, for example, consumers would have to ingest this average amount of pesticide every day for more than 25,000 days. It is clear, as the report points out, that there are days on which kids may be exposed to more; it is also clear that there are many more days when exposure is zero. Had the authors more appropriately calculated the cumulative exposures for which the safety standards are meant to apply, there would have been no risks and no warnings. Parents should feel proud, rather than guilty, of providing fruits and vegetables for their children. It is well established that a diet rich in such foods decreases the risk of heart disease and cancer. Such benefits dramatically overwhelm the theoretical risks of tiny amounts of pesticides in food. So keep serving up the peaches, apples, squash, grapes and pears.

单选题In the 1960s, medical researchers Thomas Holmes and Richard Rahe developed a checklist of stressful events. They appreciated the tricky point that any major change can be stressful. Negative events like "serious illness of a family member" were high on the list, but so were some positive life-changing events, like marriage. When you take the Holmes-Rahe test you must remember that the score does not reflect how you deal with stress—it only shows how much you have to deal with. And we now know that the way you handle these events dramatically affects your chances of staying healthy. By the early 1970s, hundreds of similar studies had followed Holmes and Rahe. And millions of Americans who work and live under stress worried over the reports. Somehow, the research got boiled down to a memorable message. Women's magazines ran headlines like "Stress causes illness. " If you want to stay physically and mentally healthy, the articles said, avoid stressful events. But such simplistic advice is impossible to follow. Even if stressful events are dangerous, many—like the death of a loved one—are impossible to avoid. Moreover, any warning to avoid all stressful events is a prescription (处方)for staying away from opportunities as well as trouble. Since any change can be stressful, a person who wanted to be completely free of stress would never marry, have a child, take a new job or move. The notion that all stress makes you sick also ignores a lot of what we know about people. It assumes we're all vulnerable (脆弱的) and passive in the face of adversity (逆境). But what about human initiative and creativity? Many come through periods of stress with more physical and mental vigor than they had before. We also know that a long time without change or challenge can lead to boredom, and physical and mental strain.

单选题Most children with healthy appetites are ready to eat almost anything that is offered them and a child rarely dislikes food (51) it is badly cooked. The way a meal is cooked and served is most important and an (52) served meal will often improve a child's appetite. Never ask a child whether he likes or dislikes a food and never (53) likes and dislikes in front of him or allow anybody else to do so. If the father says he hates fat meat or the mother refuses vegetables in the child's hearing he is (54) to copy this procedure. Take it (55) granted that he likes everything and he probably will. Nothing healthful should be omitted from the meal because of a (56) dislike. At meal times it is a good idea to give a child a small portion and let him (57) back for a second helping rather than give him as much as he is likely to eat all at once. Do not talk too much to the child (58) meal times, but let him get on with his food, and do not allow him to leave the table immediately after a meal or he will soon learn to swallow his food (59) he can hurry back to his toys. Under (60) circumstances must a child be coaxed or forced to eat.

单选题Next week, as millions of families gather for their Thanksgiving (感恩节) feasts, many other Americans will go without. According to the United States Department of Agriculture, more than 12 million households lack enough food for everyone in their family at some time during the year—including holidays. Hunger is surprisingly widespread in our country—one of the world's wealthiest—yet the government estimates that we waste almost 100 billion pounds of food each year, more than one-quarter of our total supply. Reducing this improper distribution of resources is a goal of America's Second Harvest, the nation's largest domestic hunger-relief organization. Last year, it distributed nearly 2 billon pounds of food to more than 23 million people in need. America's Second Harvest is a network of 214 inter-connected food banks and other organizations that gather food from growers, processors, grocery stores and restaurants. In turn, the network distributes food to some 50,000 soup kitchens, homeless shelters and old people's centers in every county of every state. A great deal of work is involved in distributing tons of food from thousands of donors (捐赠者) to hundreds of small, nonprofit organizations. Until a few years ago, America's Second Harvest lacked any effective way to manage their inventory. Without accurate and timely information, soup kitchens were sometimes empty while food was left to spoil in loading places. In 2000, America's Second Harvest began to use a new inventory and financial-management system—Ceres. It is software designed specifically for hunger-relief operations. It is used by more than 100 America's Second Harvest organizations to track food from donation to distribution. Ceres has helped reduce the spoiling of food and improve distribution. An evaluation found that the software streamlined food banks' operations by 23 percent in the first year alone. With more accurate and timely reports, Ceres saves time, flees staff members to focus on finding new donors, and promises more efficient use of donations. Hunger in America remains a troubling social problem. Technology alone cannot solve it. But in the hands of organizations such as America's Second Harvest, it is a powerful tool that is helping to make a difference—and helping more Americans to join in the feast.
