1．__________
The World Health Organization（WHO）says that blindness and other visual problems are the leading causes of disability of older people in low-and middle-income countries．However， some researchers disagree with WHO on this point．They made a study and found that the leading cause is dementia（痴呆）．

5．
An article published in the Lancet medical journal dealt with a special issue on disability．It was a study on disability and children in eighteen low-and middle-income countries．It indicated that in almost half of the countries， children who were breast-fed were less likely to have a disability than those who were not．The same was true of those who had a deficiency of vitamin A and those who were underweight．Children who did not take part in early learning activities or attend school were also more likely to be disabled than those who did．

Auctions are public sales of goods, conducted by an officially approved auctioneer. He asks the crowd assembled in the auction-room to make offers, or "bids", for the various items on sale. He encourages buyers to bid higher figures,and finally names the highest bidder as the buyer of the good. This is called "knocking down" the goods, for the bidding ends when the auctioneer strikes a small hammer on a table at which he stands. 2._____ The ancient Roman probably invented sales by auction, and the English word comes from the Latin auction, meaning "increase". The Romans usually sold in this way the goods taken in war. In England in the eighteenth and nineteenth centuries, goods were often sold "by the candle", a short candle was lit by the auctioneer, and bids could be made while it stayed alight. 3._____ Practically all goods whose qualities vary are sold by auction. Among these are coffee skins, wool, tea, furs, silk and wines. Auction sales are also usual for land and property. Furniture pictures, rare books, old china and similar works of art. 4. _____ An auction is usually advertised beforehand with full particulars often articles to be sold and where and when they can be viewed by potential buyers. If the advertisement cannot give full details, catalogues are printed, and each group of goods to be sold together called a "lot" is usually given a number. The auctioneer need not begin with LOT I and continue in the order of numbers, he may wait until he notices the fact that certain buyers are in the room and then produce the lots they are likely to be interested in. 5._____ The auctioneer's services are paid for in the form of a percentage of the price the goods are sold for. The auctioneer therefore has a direct interest in pushing up the bidding as high as possible. He will not waste time by starting the bidding too low. He will also play on the opponents among his buyers and succeed in getting a high price by encouraging two business competitors to bid against each other. |

1. _____ Americans are far more knowledgeable about drinks than they were 20 years ago. Witness the Starbucks revolution and you'll know where the trend goes. Now, encouraged by recent studies suggesting that it can cut the risk of cancer and heart disease and slow the aging process, tea is enjoying a similar change. Enough fashionable tea houses are springing up to make even longtime coffee drinkers consider switching drinks. 2. _____ Tea is available in more places than ever. The Tea Association of the United States reports that from 1990 to 1999, annual sales of the drink grew to $4.6 billion from $1.8 billion. "Green tea is seen by consumers as a 'functional food'" - delivering health benefits beyond food itself, says Vierhile. 3. ____ Recently published studies point out that only teas that come from the leaves of the plant Camellia sinensis have been shown to contain health benefits. Other herbal teas may taste good, yet they do little more than warm up the drinker. But for Camellia sinensis, the evidence is powerful. In a 1998 study, Harvard University researchers found that drinking one cup of black tea a day lowered the risk of heart attack by as much as 44 percent compared with non-tea drinkers, and other studies have suggested that the antioxidants (抗氧化剂) in these so-called real teas can also prevent cancer. 4._____ One such antioxidant in green tea is ECGC, a compound 20 times as powerful as vitamin E and 200 times as powerful as vitamin C. "When people ask me for something good and cheap they can do to reduce their cancer risk, I tell them to drink real tea," says Mitchell Gaynor, director of medical oncology at New York City's Strang-Cornell Cancer Prevention Center. 5. _____ Among those inspired to become a green-tea drinker is Tess Ghilaga, a New York writer who took it up after seeking advice from a nutritionist six years ago. "I've never been a coffee drinker," says Ghilaga, 33. "She told me to start drinking green tea for the antioxidant qualities." Now Ghilaga and her husband habitually make tea - they order theirs from InPursuitofTea.com, an Internet tea company. And although tea contains about half the amount of caffeine in a cup of coffee, "you still get such a kick from it," says Ghilaga. |
