摘要:(C) For years, doctors advised their patients that the only thing taking multivitamins does is to give them extensive urine (尿). After all, true vitamin deficiencies are practically unheard of in industrialized countries. Now it seems those doctors may have been wrong. The results of a growing number of studies suggest that even a modest 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. 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. 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 benefit outweighs the cost. Despite vitamin C’s great popularity, consuming large amounts of it still has not been positively linked to any great benefit. The body quickly becomes filled with C and simply excretes 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 can cause trouble, including excessive 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. 73.At one time doctors discouraged taking multivitamins because they believed that multivitamins . A.could not easily be absorbed by the human body B.were potentially harmful to people’s health C.were too expensive for daily consumption D.could not provide any cure for vitamin deficiencies 74.It can be seen that large doses of multivitamins . A.may bring about serious side effects B.may help prevent excessive bleeding C.are likely to induce the blockage of arteries D.are advisable for those with vitamin deficiencies 75.The author concludes the passage with the advice that . A.the benefit of daily multivitamin intake outweighs that of exercise and a balanced diet B.it’s risky to take multivitamins without knowing their specific function C.the potential benefit of multivitamins can never be overestimated D.it’s reasonable to take a rational dose of multivitamins daily

七选五(共5小题;每小题2分,共10分)

根据短文内容,从短文后的七个选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

The band that wasn’t

Have you ever wanted to be part of a band as a famous singer or musician? Have you ever dreamed of playing in front of thousands of people at a concert, at which everyone is clapping and appreciating your music? Do you sing karaoke and pretend you are a famous singer like Song Zuying or Liu Huan? To be honest, a lot of people attach great importance to becoming rich and famous.      1    

Many musicians meet and form a band because they like to write and play their own music. They may start as a group of high-school students, for whom practising their music in someone's house is the first step to fame. Sometimes they may play to passers-by in the street or subway so that they can earn some extra money for themselves or to pay for their instruments.      2      Of course they hope to make records in a studio and sell millions of copies to become millionaires!

     3      It was called the Monkees and began as a TV show. The musicians were to play jokes on each other as well as play music, most of which was based loosely on the Beatles. The TV organizers had planned to find four musicians who could act as well as sing. They put an advertisement in a newspaper looking for rock musicians, but they could only find one who was good enough. They had to use actors for the other three members of the band.

     4      So during the broadcasts they just pretended to sing. Anyhow their performances were humorous enough to be copied by other groups. They were so popular that their fans formed clubs in order to get more familiar with them. Each week on TV, the Monkees would play and sing songs written by other musicians. However, after a year or so in which they became more serious about their work, the Monkees started to play and sing their own songs like a real band. Then they produced their own records and started touring and playing their own music.     5     . The band broke up about 1970, but happily they reunited in the mid-1980s. They produced a new record in 1996, with which they celebrated their formal time as a real band.

A. In the USA they became even more popular than the Beatles and sold even more records.

B. The Monkees’ television show stayed on the air for years after the group broke up. .

C. However, there was one band that started in a different way.

D. But just how do people form a band?

E. Later they may give performances in pubs or clubs, for which they are paid in cash.

F. Most of us probably have our favorite performers, stars or bands, but many of us also want to discover new sounds and rhythms.

G. As some of these actors could not sing well enough, they had to rely on other musicians to help them.
