Pearls（珍珠） are valuable white gems （宝物） which come from the ocean. Actually they are 1 by oysters, small shell fish that live on the 2 of the ocean.
3 oysters（牡蛎，蚝）will make pearls; not all oysters produce them. Oysters produce pearls only when they are 4 by sand. If a 5 of sand enters the oyster's 6 , the oyster becomes hurt because the 7 grain of sand irritates（使... 不适，刺激） the smooth, soft skin of the oyster. The oyster tries to 8 itself by producing a white 9 that looks like milk. The oyster covers the 10 with a milky fluid. The fluid protects the oyster. Later the white liquid become 11 . This hardened liquid forms a shell, or bead, around the sand. At this time a pearl is beginning to 12 .
The white pearl grows 13 inside the oyster's shell. 14 , it takes about six or seven years for the oyster to produce a pearl. Not all oysters produce pearls 15 most oysters sometimes take sand into their 16 . Only sand which the oyster cannot get rid of will 17 it. In other words, if an oyster "swallows" some sand, it will manage to "spit it out". If the oyster cannot get rid of the 18 , then it will produce the white fluid to 19 itself.

For years, doctors advised their patients that only thing taking multivitamins （复合维生素）does is to give them expensive urine（尿）. After all, true vitamin deficiencies (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 proof 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 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 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. 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 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 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 help. It may turn out that vitamin E plays a role in prevention 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（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 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（剂量） 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 refinement, taking a daily multivitamin makes a lot of sense.
1. At one time doctors discouraged taking multivitamins because they believed
that multivitamins _________.
A. were 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
2. According to the author, clinical 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
3. It has been found that vitamin E _________.
A. can effectively help 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
4. It can be seen that large doses of multivitamins __________.
A. may cause serious side effects
B. may help prevent excessive bleeding
C. are likely to increase the blockage of arteries
D. are advisable for those with vitamin deficiencies
5. 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 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

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 students 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. They successfully sold 28 pictures pasted with different seeds at a campus auction a week ago. 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 many tests and lots of hard work," said Senior 2 Shi Chen, CEO of the company.
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 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 learn new skills as the leaders 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 consultants.
“They helped 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 service, 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 s
