30、 A For years, doctors advised their patients that only thing taking multivitamins (復(fù)合維生素) does is to give them expensive urine(尿). After all, true vitamin deficien?cies (shortage) are practically unheard of in industrialized countries. Now it seems those doctors may have bee

31、n wrong. The result of a growing number of studies suggest that even a modes vitamin shortfall can be harmful to your health. Although proof of the benefits of multivitamins is still far from certain, the few dollars you spend on them is probably a good investment (投資). Or at least that's the argume

32、nt put for?ward in the New England Journal of Medicine. Ideally, say Dr. Walter Willett and Dr. Meir Stampfer of Harvard, all vitamin supplements would be evaluated in scientifical?ly rigorous clinical trials (testing period). But those studies can take a long time and often raise more questions tha

33、n they answer. At some point, while researchers work on figuring out where the truth lies, it just makes sense to say the potential (潛在的) benefit outweighs the cost. The best evidence to date concerns foliate, one of the Bvitamins. It's been proved to limit the number of defects in embryos (胚胎), an

34、d a recent test found that folate in combination with vitamin B12 and a form of B6 also decreases the reblockage of ar?teries after surgical repair. The news on vitamin E has been more mixed. Healthy folks who take 400 inter?national units daily for at least two years appear somewhat less likely to

35、 develop heart disease. But when doctors give vitamin E to patients who already have heart disease, the vitamin doesn't seem to help. It may turn out that vitamin E plays a role in pre?vention but cannot undo serious damage. Despite vitamin C's great popularity, consuming large amount (數(shù)量) of it st

36、ill has not been positively linked to any great benefit. The body quickly absorbs(吸收) C and simply excretes (排泄)any excess. The multivitamins question boils down to this: Do you need to wait until all the evidence is in before you take them, or are you willing to accept that there's enough evidence

37、 that they don't hurt and could help? If the latter there's no need to go to extremes and buy the biggest horse pills or the most expensive bottles. Large doses(劑量) can cause trouble, including excessive (extreme) bleeding and nervous system problems. Multivitamins are no substitute for exercise a

38、nd a balanced diet, of course. As long as you understand that any potential benefit is modest and subject to further re?finement, taking a daily multivitamin makes a lot of sense. 36. At one time doctors discouraged taking multivitamins because they believed that multivitamins _________ . A. were

39、too expensive for daily consumption B. were potentially harmful to people's health C. could not easily be absorbed by the human body D. could not provide any cure for vitamin deficiencies 37. According to the author, clinical trials of vitamin supplements _________ . A. often result in mislea

40、ding conclusions B. take time and will not produce conclusions C. appear to be a pure waste of time and resources D. should be conducted by scientists in some other ways 38. It has been found that vitamin E _________ . A. can effectively help cure heart disease B. should be taken by patient

41、s regular and directly C. has a preventive but not curative effect on heart disease D. should be given to patients with heart disease as early as possible 39. It can be seen that large doses of multivitamins __________ . A. may cause serious side effects B. may help prevent excessive ble

42、eding C. are likely to increase the blockage of arteries D. are advisable for those with vitamin deficiencies 40. The author concludes the passage with the advice that A. people benefit more from daily multivitamins than a balanced diet B. people should expect multivitamins to be used to cure

43、diseases C. it's risky to take multivitamins without listening to the doctors D. it's reasonable to take a proper amount of multivitamins daily B What do you see from a handful of seeds? Some see green plants, some see blooming flowers, or just seeds. But one

44、 group of Shanghai students saw an opportu?nity to make money. Eight students from No 2 Secondary School Attached to East China Normal Uni?versity started a virtual company selling different seeds and seed products. They successfully sold 28 pictures pasted with different seeds at a campus auction

45、a week a?go. The company, which has recruited around 20 student staff members, has earned over 2000 yuan in the past three months. "We donated part of the money to a poor school in the countryside of Anhui Province. It's great to realize our ideal of ‘spreading love and culture with seeds’ after ma

46、ny tests and lots of hard work," said Senior 2 Shi Chen, CEO of the compa?ny. Just like any other company, Shi's didn't develop smoothly. Shi and her young colleagues used to sell fresh flowers and old books, and later found seeds might be something that their company could engage in. They bought s

47、eeds of various plants and flowers at low prices from a local farm and sold them in schools or on streets. The creative students also made accessories and pictures with different seeds. With little business knowledge, the students had to learn new skills as the lead?ers of different departments, su

48、ch as public relations (PR), sales and marketing. They persuaded a joint Sino-French company near their school to give them training in business management. They also asked some local businessmen to act as their consul?tants. "They helped us overcome our shyness. We also learned quite a lot of bu

49、siness theory. I found communication skills and teamwork are very important for my job," said Senior 1 Qian Yifei. The 16-year-old was elected as PR manager thanks to her talent for speaking. She is also in charge of after sales service, dealing with complaints and providing suggestions. As the he

50、ad of the company, CEO Shi has a lot more to think about. First of all, she has to learn how to make her colleagues work efficiently as the company only opens at weekends due to all their studies. So she established a system to evaluate every one's performance, in terms of punctuality, efficiency, p

51、rofits knowledge and so on. "It makes the company more formal," she said. 41. At a campus auction a week ago, they ________ . A. sold 28 green plants with different flowers B. sold 28 seeds pasted with different pictures C. sold 28 pictures pasted with different seeds D. sold 28 flowers paste
