单选题Consumers are being confused and misled by the hodge-podge of environmental claims made by household products, according to a "green labeling" study published by Consumers International Friday. Among the report"s more outrageous findings—a German fertilizer described itself as "earthworm friendly", a brand of flour said it was "non-polluting" and a British toilet paper claimed to be "environmentally friendlier". The study was written and researched by Britain"s National Consumer Council (NCC) for lobby group Consumer International. It was funded by the German and Dutch governments and the European Commission. "While many good and useful claims are being made, it is clear there is a long way to go in ensuring shoppers are adequately informed about the environmental impact of products they buy," said Consumers International director Anna Fielder. The 10-country study surveyed product packaging in Britain, Western Europe, Scandinavia and the United States. It found that products sold in Germany and the United Kingdom made the most environmental claims on average. The report focused on claims made by specific products, such as detergent insect sprays and by some garden products. It diet not test the claims, but compared them to labeling guidelines set by the International Standards Organization (ISO) in September, 1999. Researchers documented claims of environmental friendliness made by about 2,000 products and found many too vague or too misleading to meet ISO standards. "Many products had specially-designed labels to make them seem environmentally friendly, but in fact many of these symbols mean nothing," said report researcher Philip Page. "Laundry detergents made the most number of claims with 158 household cleaners were second with 145 separate claims, while paints were third on our list with 73. The high numbers show how very confusing it must be for consumers to sort the true from the misleading." he said. The ISO labeling standards ban vague or misleading claims on product packaging, because terms such as "environmentally friendly" and "non-polluting" cannot be verified. "What we are now pushing for is to have multinational corporations meet the standards set by the ISO." said Page.

单选题According to a survey, which was based on the responses of over 188,000 students, today's traditional-age college freshmen are "more materialistic and less altruistic (利他主义的) than at any time in the 17 years of the poll. Not surprising in these hard times, the students' major objective "is to be financially well off. Less important than ever is developing a meaningful philosophy of life." It follows then that today the most popular course is not literature or history but accounting. Interest in teaching, social service and the "altruistic" fields is at a low. On the other hand, enrollment in business programs, engineering and computer science is way up. That's no surprise either. A friend of mine (a sales representative for a chemical company) was making twice the salary of her college instructors in her first year on the job—even before she completed her two-year associate degree. While it's true that we all need a career, it is equally true that our civilization has accumulated an incredible amount of knowledge in fields far removed from our own and that we are better for our understanding of these other contributions—be the scientific or artistic. It is equally true that, in studying the diverse wisdom of others, we learn how to think. More important, perhaps, education teaches us to see the connections between things, as well as to see beyond our immediate needs. Weekly we read of unions who went on strike for higher wages, only to drive their employer out of business. No company; no job. How shortsighted in the long run. But the most important argument for a broad education is that in studying the accumulated wisdom of ages, we improve our moral sense. I saw a cartoon recently which shows a group o businessmen looking puzzled as they sit around a conference table; one of them is talking on the intercom (对讲机) : "Miss Baxter," he says, "could you please send in someone who can distinguish right from wrong?" From the long-term point of view, that's what education really ought to be about.

单选题Generations of Americans have been brought up to believe that a good breakfast is one of life's essentials. Eating breakfast at the start of the day, we have all been told, is as necessary as putting gasoline in the family car before starting a trip. But for many people the thought of food first thing in the morning is by no means a pleasure. So despite all the efforts, they still take no breakfast. Between 1977 and 1983, the latest years for which figures are available, the number of people who didn't have breakfast increased by 33 percent—from 8. 8 million to 11. 7 million—according to the Chicago-based Market Research Corporation of America． For those who feel pain or guilt about not eating breakfast, however, there is some good news. Several studies in the last few years indicate that, for adults especially, there may be nothing wrong with omitting breakfast. "Going without breakfast does not affect performance. " said Arnold E. Bender, the former professor of nutrition at Queen Elizabeth College in London, "nor does giving people breakfast improve performance. " Scientific evidence linking breakfast to better health or better performance is surprisingly inadequate, and most of the recent work involves children, not adults. "The literature," says one researcher, Dr. Ernesto Pollitt at the University of Texas, "is poor".

单选题Obesity generally is defined as an accumulation of fat(adipose tissue) beyond what is considered normal for a person's age, sex, and body type. In today's society obesity is considered as a disease, not a moral failing. It occurs when energy intake exceeds the amount of energy expended over time. Only in a small minority of cases is obesity caused by such illnesses as hypothyroidism, or the result of taking medications, such as steroids, that can cause weight gain. The more a person weighs, the more blood vessels the body needs to circulate blood throughout the body. The heart takes on a heavy burden as it has to pump harder to force the blood flow through so many vessels, As a result, the heart grows in size and blood pressure tends to rise. Obesity is also a factor in osteoarthritis (because of the extra weight placed on joints), gout, bone and joint diseases(including ruptured intervertebral discs), varicose veins, respiratory ailments; gallbladder disease, complications during pregnancy and delivery, and higher accidental death rate. Obesity can alter hormone levels, affect immune function, and cause impotence in men and reproductive problems in women. Women who are 30% overweight are twice as likely to die of endometrial cancer, and those who are 40% overweight have four times the risk. Obese women also are more likely to incur cancers of the breast, cervix, ovaries, and gallbladder. Obese men are more likely to develop cancers of the rectum, colon, esophagus, bladder, pancreas, stomach, and prostate. Obesity can also cause psychological problems. Sufferers are associated with laziness, failure, or inadequate willpower. As a result, overweight men and women blame themselves for being heavy, thus causing feelings of guilt and depression. Scientific evidence has found an association between MBI(body-mass index) and higher death rates. However, the relative risk of being heavy declines with age. Some researchers have found that data linking overweight and death are inconclusive, while other researchers have found that losing weight may be riskier than dangers posed by extra pounds. Some researchers counter that overweight indirectly contributes to over 300,000 deaths a year. A poll by Shape Up America found that 78% of overweight or obese adults have abandoned dieting as a means of losing weight. Diets do not teach people how to eat properly. They merely restrict food intake temporarily, so when the diet ends, weight gain r
