You counted on the stability of housing prices and depended on bankers to be, well, dependable. And you figured that taking vitamins was go

38、od for you. Oh, its painful when another myth gets shattered. Recent research suggests that a daily multivitamin is a waste of money for most peopleand theres growing evidence that some other old standbys may even hurt your health. Last year, researchers published new findings from the Womens Health

39、 Initiative, a long-term study of more than 160,000 midlife women. The data showed that multivitamin-takers are no healthier than those who dont pop the pills. Vitamin supplements came into vogue in the early 1900s, when it was difficult for most people to get a wide variety of fresh fruits and vege

40、tables year-round. Back then, vitamin-deficiency diseases werent unheard-of: the bowed legs and deformed ribs of rickets (caused by a severe shortage of vitamin D) or the skin problems. But these days, youre extremely unlikely to be seriously deficient if you eat an average American diet. Most of us

41、 could do with a couple more daily servings of produce, but a multi doesnt do a good job at substituting for those. Experts say multivitamins have maybe two dozen ingredients-but plants have hundreds of other useful compounds. If you just take a multivitamin, youre missing lots of compounds that may

42、 be providing benefits. Another myth about vitamin is that vitamin C could prevent colds. Today, drugstores are full of vitamin C-based remedies. Studies say: Buyer, beware. Recently, researchers analyzed a raft of studies going back several decades and involving more than 11,000 subjects to arrive

43、at a disappointing conclusion: Vitamin C didnt ward off colds, except among marathoners, skiers, and soldiers on subarctic exercises. Then can the vitamin cut the length of colds? Yes and no. Taking the vitamin daily does seem to reduce the time youll spend sniffling-but not enough to notice. Adults

44、 typically have cold symptoms for 12 days a year; a daily pill could cut that to 11 days. Kids might go from 28 days of runny noses to 24 per year. The researchers conclude that minor reductions like these dont justify the expense and bother of year-round pill-popping (taking C only after symptoms c

45、rop up doesnt help). Some people would think that vitamin pills might not help you, but they cant hurt either. However, a series of large-scale studies has turned this thinking on its head. Studies have raised concerns that taking high doses of folic acid could raise the risk of colon cancer. Still

46、others suggest a connection between high doses of some vitamins and heart disease. Some expert says vitamins are safe when you get them in food, but in pill form, they can act more like a drug with the potential for unexpected and sometimes dangerous effects. 81 At the beginning of the passage, the

47、author indicates that （ A） bankers could be depended on. （ B） housing prices would always remain stable. （ C） vitamins bring benefits to people. （ D） myth about vitamins is no longer believable. 82 According to the passage, vitamin-deficiency diseases were caused by （ A） not taking vitamin pills. （

48、B） not having various fruits and vegetables. （ C） eating an average American diet. （ D） shortage of vitamind. 83 The phrase “ward off in the fourth paragraph is closest in meaning to （ A） cure. （ B） keep away. （ C） worsen. （ D） relieve. 84 Whats experts opinion about taking vitamin pills? （ A） It is

49、 safe for our health. （ B） It does more good than harm. （ C） It may bring us some side effects. （ D） It will reduce the length of colds. 85 From the passage, we learn that the author （ A） feels it necessary to take vitamin pills. （ B） thinks pill-takers are healthier than those who dont. （ C） suggests high doses of vitamins may result in heart disease. （ D） finds out an unsatisfied conclusion about taking multivitamins. 85 Open up most fashion magazines and you will see incredibly thin models with impossible hair and wearin
