[听力原文]11-15All mammals, except man and the monkey, swim naturally from birth. For man, like the monkey, it is not instructive to float. Deaths by drowning are common every where. In the United States alone, about 7,000 children under four drown each year.Everything possible is done to prevent such tragedies. One solution’ s particularly effective--teaching children to swim while they are still babies. Most large towns in Florida and California already run lessons for babies and infants. The idea has spread to Europe where, in several countries, special courses are now arranged for children from seven to twenty - four months.The first step is to eliminate the child’ s fear of the water. Next, he’s taught to float. Once he can do this naturally and without fear, the child grasps the technique and can push forward himself through the water. How many children under four drawn each year in the United States（）

Whenever a French novel is translated into English, the edition sold in Britain should be in British English. If the edition sold in Britain were in American English, its idioms and spellings would appear to British readers to be strikingly American and thus to conflict with the novel’s setting. The recommendation is based on which of the following assumptions
Cordia Harrington was tired of standing up all day and smelling like French fries at night. She also owned and operated three McDonald’s franchises (特许经销商) in Illinois, but as a divorced mother of three boys, she yearned for a business that would provide for her children and let her spend more time with them. Her turning moment struck, strangely enough, after she was nominated in 1992 to be on the McDonald’s bun committee. "The other franchisees, all men, thought that was funny because of the word bun," she re calls. "But the joke was on them: They didn’t know the company would be picking me up in a corporate jet to see bakeries around the world. Every time I went to a meeting, I loved it. This was global!" The experience opened her eyes to business possibilities. When McDonald’s decided it wanted a new bun supplier, Harrington became determined to win the contract, even though she had no experience running a bakery. "You see a tiny crack in the door, and you have to run through it," she says. "I really believed I could do this." Harrington studied the bakery business and made sure she was never off executives’ view. "If you have a dream, you can’t wait for people to call you," she says. "So I’d visit a mill and send them photos of myself in a baker’s hat and jacket, holding a sign that said I want to be your baker." After four years and 32 inter views, her persistence paid off. Harrington sealed the deal with a handshake, sold her franchises, invested everything she owned, and borrowed $13.5 million. She was ready to build the fastest, most automated bakery in the world. The Tennessee Bun Company opened ahead of schedule in 1997, in time for a decline in US fast-food sales for McDonald’s. Before Harrington knew it, she was down to her last $ 20 000, not enough to cover payroll. And her agreement with McDonald’s required that she sell exclusively to the company. "I cried my self to sleep many nights," she recalls. "I really did think, I am going to go bankrupt." But Harrington worked out an agreement to supply Pepperidge Farm as well. "McDonald’s could see a benefit if our production went up and prices went down, and no benefit if we went out of business," she says. "That deal saved us." Over the next eight years, Harrington branched out even more: She started her own trucking business, added a cold-storage company, and now has three bakeries all now known as the Bun Companies. Harrington branched out and she has three bakeries with the common name of ______.
While the world’s flu fighters have concentrated on countering the H1N1 swine flu, bird flu H5N1 has quietly continued to take its (62) on both poultry and humans. Last year, 17 countries, (63) from Germany to Japan, reported outbreaks of H5N1 in (64) poultry and wild birds; and the World Health Organization, which still says H5N1 causes a worldwide threat, recoded 72 human (65) , 32 of them fatal. The major outbreak, entering its (66) year, is still in the developing countries of Asia. Indonesia (67) accounted for 19 of the 32 H5N1 deaths; Vietnam, (68) 5. But there are signs of (69) . The number of human deaths has been (70) since peaking at 79 in 2006. And fewer countries reported outbreaks in 2009 than in 2008. Partnership researchers compared notes on the effectiveness of control measures. Scientists reported that carefully (71) killing can be just as effective as wide spread killing, and less (72) . Others reported that reducing risk among those (73) backyard poultry has to be a community-wide effort, since changing the practices of (74) farmers has proven difficult. In particular, Science Insider reported that a 3- year-old regional investigation network is making (75) in sorting out the role of wild birds. Some water birds (76) thought to be spreading the virus, such as the Asian open bill stork, are now known to quickly die of H5N1 infection, Wiriyarat says. But pas serine species , or perching birds, are apparently (77) the virus without ill effects, says an Asian zoologist. He also adds that there is a high (78) of outbreaks in poultry and passerine movements. Wiriyarat says it is still (79) what is causing the outbreak, whether there is a natural storage for H5N1, and how the virus is (80) between domestic and wild birds. But while that research continues, the most effective way to reduce the amount of virus in (81) is to control outbreaks in poultry, he says.
