单选题He shouldn't have come back alive. Captain J. H. Hedley was British pilot in World War I. He fell victim to a bit of misfortune that would have been enough to kill anyone. Yet, with bad luck staring him in the face, good luck was coming up fast on his tail. Captain Hedley was flying a mission over Germany with his copilot, A Canadian flyer named Makepeace. Suddenly they were surrounded by a group of German fighters. Makepeace, an experienced pilot, knew he had to take the plane into a vertical dive in order to slip away from Germans. Inexplicably, Hedley was caught unaware by his copilot's maneuver. He was thrown sharply out of his seat and out of the plane. Makepeace sadly counted Hedley a dead man and continued his evasive maneuvers. Suddenly, Makepeace spotted Hedley clinging to the tail of the plane, Hedley hung on and pulled himself back into the plane when it leveled off. Makepeace was stunned by the sight of Hedley, but he kept his composure enough to get them out of the trouble and out of Germany. The best explanation for Hedley's reprieve(缓刑) was that the plane's sudden vertical dive had created a vacuum in the air be- hind it. Hedley fell into the vacuum and was pulled along until he grabbed the tail and made his fantastic reentry.

单选题 English as a Foreign Language Who taught you to speak English? Your parents, while you were a young child? Your teachers at school? Perhaps even the BBC as a grown-up. Whoever it was, somehow you have developed an understanding of what is rapidly becoming a truly global language. There are now about 376 million people who speak English as their first language, and about the same number who have learnt it in addition to their mother tongue. There are said to be one billion people learning English now and about 80% of the information on the Internet is in English. Is this a good thing, or a bad thing? Should we celebrate the fact that more and more of us can communicate, using a common language, across countries and cultures (文化)? Or should we worry about the dangers of "mono-culturalism", a world in which we all speak the same language, eat the same food and listen to the same music? Does it matter if an increasing number of people speak the same language? On the contrary (相反), I would have thought—although I have never accepted the argument that if only we all understood each other better, there would be fewer wars. Ask the people of India (where many of them speak at least some English) and Pakistan (the same situation with India)… If we all speak English, will we then all start eating McDonalds hamburgers? Surely not. If English becomes more dominant(占主导地位的) ,will it kill other languages? I doubt it. When I travel in Africa or Asia, I am always surprised by how many people can speak not only their own language but often one or more other related languages, as well as English and perhaps some French or German as well. When we discussed this on Talking Point a couple of years ago, we received a wonderfully poetic email from a listener in Ireland. "The English language is a beautiful language. Maybe it's like a rose," he said. "But who would ever want their garden just full of roses?" Well, I love roses, and I think they make a beautiful addition to any garden. But the way I see it, just by planting a few roses, you don't necessarily need to pull out everything else. If more and more people want to plant English roses, that's fine by me.

单选题Although Julia Roberts has had much professional success. In spite of her trouble with several failed relationships.

单选题 A bite of a cookie containing peanuts could cause the airway to constrict fatally. Sharing a toy with another child who had earlier eaten a peanut butter and jelly sandwich could raise a case of hives. A peanut butter cup dropped in a Halloween bag could contaminate the rest of the treats, posing an unknown risk. These are the scenarios that "make your bone marrow turn cold" according to L.Val Giddings, vice president for food and agriculture of the Biotechnology Industry Organization. Besides representing the policy interests of food biotech companies in Washington, D. C. , Giddings is the father of a four-year-old boy with a severe peanut allergy. Peanuts are only one of the most allergenic foods; estimates of the number of people who experience a reaction to the beans hover around 2 percent of the population. Giddings says that peanuts are only one of several foods that biotechnologists are altering genetically in an attempt to eliminate the proteins that do great harm to some people's immune systems. Although soy allergies do not usually cause life-threatening reactions, the scientists are also targeting soybeans, which can be found in two thirds of all manufactured food, making the supermarket a minefield for people allergic to soy. Biotechnologists are focusing on wheat, too, and might soon expand their research to the rest of the "big eight" allergy-inducing foods: tree nuts, milk, eggs, shellfish and fish. Last September, for example, Anthony J.Kinney, a crop genetics researcher at DuPont Experimental Station in Wilmington, Del., and his colleagues reported using a technique called RNA interference (RNAi) to silence the genes that encode p34, a protein responsible for causing 65 percent of all soybean allergies. RNAi exploits the mechanism that cells use to protect themselves against foreign genetic material; it causes a cell to destroy RNA transcribed from a given gene, effectively turning off the gene. Whether the public will accept food genetically modified to be low-allergen is still unknown. Courtney Chabot Dreyer, a spokesperson for Pioneer Hi-Bred International, a subsidiary of DuPont, says that the company will conduct studies to determine whether a promising market exists for low-allergen soy before developing the seeds for sale to farmers. She estimates that Pioneer Hi-Bred is seven years away from commercializing the altered soybeans. Doug Gurian-Sherman, scientific director of the biotechnology project at the Center for Science in the Public Interest-a group that has advocated enhanced Food and Drug Administration oversight for genetically modified foods-comments that his organization would not oppose low-allergen foods if they prove to be safe. But he wonders about "identity preservation" — a term used in the food industry to describe the deliberate separation of genetically engineered and nonengineered products. A batch of nonengineered peanuts or soybeans might contaminate machinery reserved for low-allergen versions, he suggests, reducing the benefit of the gene-altered food. Such issues of identity preservation could make low-allergen genetically modified foods too costly to produce, Chabot Dreyer admits. But, she says, "it's still too early to see if that's true."
