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 (爬行动物) species and 24 per cent of butterflies (蝴蝶) 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 (证书) for nature reserves (自然保护区) of me highest quality, and Dr. 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 (户外娱乐) 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 (缩小) to become mere islands in a spoiled and highly polluted landmass."

单选题{{B}}第二篇{{/B}} {{B}} Supermarket{{/B}} Most supermarkets need a very large floor area, sometimes at least ten times as big as that of an ordinary shop. There are usually two doors, one as an entrance and the other as an exit. The rest of the side facing the street is largely of plate glass, with goods or advertising material displayed. The other three walls are normally decorated in light colours, giving an impression of cleanliness (清洁)and brightness. Most supermarkets are on one floor only. Goods being stored in rooms at the back or upstairs. At right-angles to the window stretch long structures about six feet high with a number of shelves on each side. Similar shelf units or frozen food containers extend round the walls. Broad aisles(通道)between the shelf units and ample(足够的)space between them and the window and also the far wall allow room for the circulation of many people. Individual commodities(商品), in tins, bags, boxes or other containers, are stacked (堆放) in groups on the shelves, and each group is labelled with a price ticket. Metal baskets near the entrance are taken by the shoppers who collect in them the goods they select from the shelves. Between the shelf units and the window in one half of the shops are a number of small counters about three feet high. Beside each sits a cashier (现金出纳员), who operates a machine for reckoning, detailing the cost of each customer's purchases. The customer places the basket at one end of the counter so that it can be emptied by the cashier who records the price of the commodities one by one, before putting each on a moving section of the counter top. The goods are collected and packed into the customer's bag by another assistant at the end of the counter. The cashier finally hands a printed slip recording all prices to the customer, who pays the total, collects the bag and leaves.
