单选题Preserving Nature for Future Demands for stronger protection for wildlife in Britain sometimes hide the fact that similar needs are felt in the rest of Europe. Studies by the Council of Europe, of which 21 countries are members, have shown that 45 per cent of reptile species and 24 per cent of butterflies are in danger of dying out. European concern for wildlife was outlined by Dr. Peter Baum, an expert in the environment and natural resources division of the council, when he spoke at a conference arranged by the administrators of a British national park. The park is one of the few areas in Europe to hold the council"s diploma for nature reserves of the highest quality, and Dr. Peter Baum had come to present it to the park once again. He was afraid that public opinion was turning against national parks, and that those set up in the 1960s and 1970s could not be set up today. But Dr. Baum clearly remained a strong supporter of the view that natural environments needed to be allowed to survive in peace in their own right. "No area could be expected to survive both as a true nature reserve and as a tourist attraction," he went on. "The short-sighted view that reserves had to serve immediate human demands for outdoor recreation should be replaced by full acceptance of their importance as places to preserve nature for the future." "We forget that they are the guarantee of life systems, on which any built-up area ultimately depends," Dr. Baum went on. "We could manage without most industrial products, but we could not manage without nature. However, our natural environment areas, which are the original parts of our countryside, have shrunk to become mere islands in a spoiled and highly polluted land mass. "

单选题Knitting My mother knew how to knit (编织), but she never taught me. She assumed, as did many women of her generation, that knitting was no longer a skill worth passing down from mother to daughter. A combination of feminism (女权主义) and consumerism (消费主义) made many women feel that such homely accomplishments were now out of date. My Grandmother still knitted, though, and every Christmas she made a pair of socks for my brother and me, of red wool (毛线). They were the ones we wore under our ice skates (冰鞋), when it was really important to have warm feet. Knitting is a nervous habit that happens to be productive. It helped me quit smoking by giving my hands something else to do. It is wonderful for depression because no matter what else happens, you are creating something beautiful. Time spent in front of the television or just sitting is no longer time wasted. I love breathing life into the patterns. It's true magic, finding a neglected, dog-eared (翻旧了的) old book with the perfect snowflake design, buying the same Germantown wool my grandmother used, in the exact blue to match my daughter's eyes, taking it on the train with me every day for two months, working enthusiastically to get it done by Christmas, staying up late after the stockings are filled to sew in the sleeves and weave in the ends. Knitting has taught me patience. I know that if I just keep going, even if it takes months, there will be a reward. When I make a mistake, I know that anger will not fix it, and that I just have to go back and start over again. People often ask if I would do it for money, and the answer is always a definite no. In the first place, you could not pay me enough for the hours I put into a sweater. But more important, this is an activity I keep separate from such considerations. I knit to cover my children and other people I love in warmth and color. I knit to give them something earthly that money could never buy. Knitting gives my life an alternative rhythm to the daily deadline. By day I can write about Northern Ireland or the New York City Police Department and get paid for it, but on the train home, surrounded by people with laptops, I stage my little rebellion. I take out my old knitting bag and join the centuries of women who have knitted for love.

单选题Telling Tales about People One of the most common types of nonfiction, and one that many people enjoy reading, is stories about people"s lives. These stories fall into three general categories: autobiography, memoir, and biography. An autobiography is the story of a person"s life written by himself or herself. Often it begins with the person"s earliest recollections and ends in the present. Autobiography writers may not be entirely objective in the way they present themselves. However, they offer the reader a good look at the way they are and what makes them that way. People as diverse as Benjamin Franklin and Helen Keller have written autobiographies. Other writers, such as James Joyce, have written thinly fictionalized accounts of their lives. These are not autobiographies, hut they are very close to it. Memoirs, strictly speaking, are autobiographical accounts that focus as much on the events of the times as on the life of the author. Memoir writers typically use these events as backdrops for their lives. They describe them in detail and discuss their importance. Recently, though, the term memoir seems to be becoming interchangeable with autobiography. A memoir nowadays may or may not deal with the outside world. Biographies are factual accounts of someone else"s life. In many senses, these may be the hardest of the three types to write. Autobiography writers know the events they write about because they lived them. But biography writers have to gather information from as many different sources as possible. Then they have to decide which facts to include. Their goal is to present a balanced picture of a person, not one that is overly positive or too critical A fair well-presented biography may take years to research and write.

单选题{{B}}第三篇{{/B}} {{B}}Early or Later Day Care{{/B}} The British psychoanalyst John Bowlby maintains that separation from the parents during the sensitive "attachment" period from birth to three may scar a child's personality and predispose to emotional problems in later life. Some people have drawn the conclusion from Bowlby's work that children should not be subjected to day care before the age of three because of the parental separation it entails, and many people do believe this. But there are also arguments against such a strong conclusion. Firstly, anthropologists point out that the insulated love affair between children and parentsfound in modem societies does not usually exist in traditional societies. For example, in some tribal societies, such as the Ngoni, the father and mother of a child did not rear their infant alone--far from it. Secondly, common sense tells us that day care would not be so widespread today if parents, care-takers found children had problems with it. Statistical studies of this kind have not yet been carded out, and even if they were, the results would be certain to be complicated and controversial. Thirdly, in the last decade there have been a number of careful American studies of children in day care, and they have uniformly reported that day care had a neutral or slightly positive effect on children's development. But tests that have had to be used to measure this development are not widely enough accepted to settle the issue. But Bowlby's analysis raises the possibility that early day care has delayed effects. The possibility that such care might lead to, say, more mental illness or crime 15 or 20 years later can only be explored by the use of statistics. Whatever the long-term effects, parents sometimes find the immediate effects difficult to deal with. Children under three are likely to protest at leaving their parents and show unhappiness. At the age of three or three and a half almost all children find the transition to nursery easy, and this is undoubtedly why more and more parents make use of child care at this time. The matter, then, is far from clear-cut, though experience and available evidence indicate that early care is reasonable for infants.
