After all, true vitamin deficiencies (sh
16、ortage) are practically unheard of in industrialized countries. Now it seems those doctors may have been 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 certa
17、in, the few dollars you spend on them is probably a good investment (投资 ). Or at least thats the argument put forward 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 scientifically rigorous clinic
18、al trials (testing period). But those studies can take a long time and often raise more questions than they answer. At some point, while researchers work on figuring out where the truth lies, it just makes sense to say the potential (潜在的 ) benefit outweighs the cost. The best evidence to date concer
19、ns foliate, one of the Bvitamins. Its been proved to limit the number of defects in embryos (胚胎 ), and a recent test found that folate in combination with vitamin B12 and a form of B6 also decreases the reblockage of arteries after surgical repair. The news on vitamin E has been more mixed. Healthy
20、folks who take 400 international units daily for at least two years appear somewhat less likely to develop heart disease. But when doctors give vitamin E to patients who already have heart disease, the vitamin doesnt seem to help. It may turn out that vitamin E plays a role in pre-vention but cannot
21、 undo serious damage. Despite vitamin Cs great popularity, consuming large amount (数量 ) of it still 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 t
22、he evidence is in before you take them, or are you willing to accept that theres enough evidence that they dont hurt and could help? If the latter theres no need to go to extremes and buy the biggest horse pills or the most expensive bottles. Large doses(剂量 ) can cause trouble, including excessive (
23、extreme) bleeding and nervous system problems. Multivitamins are no substitute for exercise and a balanced diet, of course. As long as you understand that any potential benefit is modest and subject to further refinement, taking a daily multivitamin makes a lot of sense. 36. At one time doctors disc
24、ouraged taking multivitamins because they believed that multivitamins _ . A. were too expensive for daily consumption B. were potentially harmful to peoples 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, cl
25、inical trials of vitamin supplements _ . A. often result in misleading 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
26、 cure heart disease B. should be taken by patients 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. ma
27、y help prevent excessive bleeding 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 multivitami
28、ns to be used to cure diseases C. its risky to take multivitamins without listening to the doctors D. its 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 group of Shanghai st
29、udents saw an opportunity to make money. Eight students from No 2 Secondary School Attached to East China Normal University started a virtual company selling different seeds and seed products.

31、k,“ said Senior 2 Shi Chen, CEO of the company. Just like any other company, Shis didnt 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 seeds of various plants and flower
32、s 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 leaders of different departments, such as public relations (PR), sales
33、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 consultants. “They helped us overcome our shyness. We also learned quite a lot of business theory. I found communication sk
34、ills 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.

35、 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.
