After all, true vitamin deficiencies (shortage) are practic
24、ally 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 certain, the few dollars
25、 you spend on them is probably a good investment (投资). Or at least thats the argument put forward 每天发布最有价值的高考资源5 / 10in 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 clinica
26、l 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 concerns
27、foliate, one of the B vitamins. Its been proved to limit the number of defects in embryos (胚胎), and a recent test found that foliate 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 fol
28、ks 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 prevention but cannot und
29、o 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 the eviden
30、ce 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 (extreme) bl
31、eeding 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 discouraged takin
32、g multivitamins because they believed that multivitamins _ .A. were too 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
33、 vitamin supplements _ .A. often result in misleading conclusionsB. 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 ways38.

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 disease

Some see green plants, some see blooming flowers, or just seeds. But one group of Shanghai students saw an opportunity to ma
37、ke money.Eight students from No 2 Secondary School Attached to East China Normal University started a virtual company selling different seeds and seed products. They successfully sold 28 pictures pasted with different seeds at a campus auction a week ago. The company, which has recruited around 20 s
38、tudent 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. Its great to realize our ideal of spreading love and culture with seeds after many tests and lots of hard work,“ said Senior 2 Shi Chen, CEO o
39、f 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 flowers at low prices from a local farm
40、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 and marketing. They persuaded a joi
