23、pensive urine（尿）.After all, true vitamin deficien? cies （shortage） 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 pro

24、of of the benefits of multivitamins is still far from certain, the few dollars you spend on them is probably a good investment （ 投资）.Or at least that's the argument put for? ward in the New England Journal of Medicine. Ideally, say Dr. Walter Willett and Dr. Meir Stampfer of Harvard, all vitamin

25、 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 than they answer. At some point, while researchers work on figuring out where the truth lies, it just makes sense to say the potential

26、（潜在的）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）,and a recent test found that folate in combination with vitamin B12 and a form of B6 also decreases the reblockage of ar? teries after

27、 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 develop heart disease. But when doctors give vitamin E to patients who already have heart disease, the vitamin doesn't seem to

28、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 （数量）of it still has not been positively linked to any great benefit. The body quickly absorbs（ 吸收）C and simply excretes （ NE 泄）any excess.

29、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 that they don't hurtand could help?If the latter there's no need to go to extremes and buy the biggest horse pil

30、ls or the most expensive bottles. Large doses(齐ij量)can cause trouble, including excessive (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

31、re?finement, taking a daily multivitamin makes a lot of sense.36. At one time doctors discouraged taking multivitamins because they believed that multivitaminsA. were too expensive for daily consumptionB. were potentially harmful to people's healthC. could not easily be absorbed by the human bod

32、yD. could not provide any cure for vitamin deficiencies37. According to the author, clinical trials of vitamin supplementsA. often result in misleading conclusionsB. take time and will not produce conclusionsC. appear to be a pure waste of time and resourcesD. should be conducted by scientists in so

33、me 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 but not curative effect on heart diseaseD. should be given to patients with heart disease as early as possible39. It can be seen that lar

34、ge doses of multivitamins.A. may cause serious side effectsB. may help prevent excessive bleedingC. are likely to increase the blockage of arteriesD. are advisable for those with vitamin deficiencies40. The author concludes the passage with the advice thatA. people benefit more from daily multivitam

35、ins than a balanced dietB. people should expect multivitamins to be used to cure diseasesC. it's risky to take multivitamins without listening to the doctors D. it's reasonable to take a proper amount of multivitamins dailyBWhat do you see from a handful of seeds? Some see green plants, some

36、 see blooming flowers, or just seeds. But one 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 past

37、ed with different seeds at a campus auction 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

39、t be something that their company could engage in. They bought seeds 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

40、 learn new skills as the lead?ers of different departments, such 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 h

41、elped us overcome our shyness. We also learned quite a lot of business 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 ser

42、vice, dealing with complaints and providing suggestions.As the head 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 evaluat
