After all, true vitamin deficiencies (shortage) are practically unheard of in industrialized countries. Now it

16、 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 certain, the few dollars you spend on them is probably a good investment (投

17、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 clinical trials (testing period). But those studies can take a long time and

18、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 concerns foliate, one of the Bvitamins. Its been proved to limit the number of

19、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 folks who take 400 international units daily for at least two years appear

20、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 prevention but cannot undo serious damage.Despite vitamin Cs great popularity, consuming large am

21、ount (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 the evidence is in before you take them, or are you willing to accept that theres

22、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 (extreme) bleeding and nervous system problems.Multivitamins are no substitute for e

23、xercise 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 discouraged taking multivitamins because they believed that multivitamins _ .A. were too

24、expensive for daily consumption B. were potentially harmful to peoples healthC. could not easily be absorbed by the human body D. could not provide any cure for vitamin deficiencies37. According to the author, clinical trials of vitamin supplements _ .A. often result in misleading conclusionsB. take

25、 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 ways38. It has been found that vitamin E _ .A. can effectively help cure heart diseaseB. should be taken by patients regular and directlyC. has a preventive bu

26、t not curative effect on heart diseaseD. should be given to patients with heart disease as early as possible39. It can be seen that large doses of multivitamins _ .A. may cause serious side effects B. may help prevent excessive bleedingC. are likely to increase the blockage of arteriesD. are advisab

27、le for those with vitamin deficiencies40. The author concludes the passage with the advice thatA. people benefit more from daily multivitamins than a balanced diet B. people should expect multivitamins to be used to cure diseases C. its risky to take multivitamins without listening to the doctors D.

28、 its reasonable to take a proper amount of multivitamins daily BWhat do you see from a handful of seeds? Some see green plants, some see blooming flowers, or just seeds. But one group of Shanghai students saw an opportunity to make money.Eight students from No 2 Secondary School Attached to East We

29、donated part of the money to a poor school in the countryside of Anhui 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 va

30、rious 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 leaders of different departments, such as public

31、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 consultants.They helped us overcome our shyness. We also learned quite a lot of business theory. I fo

32、und 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.
