问题    By 2010, half the recoverable material in Britain’s dustbins will be recycled—that, at least, was the target set by Chris Patten, Secretary of State for the Environment. But he gave no clues as to how Britain should go about achieving it. While recycling enthusiasts debate the relative merits of different collection systems, it will largely be new technology, and the opening up of new markets, that makes Patten’s target attainable: a recycling scheme is successful only if manufacturers use the recovered materials in new products that people want to buy.
   The first question is how best to separate clean element—glass containers, plastics, and some paper and metal containers that is relatively clean when discarded—from mixed refuse. This clean element is the main target for Britain’s recyclers. The method of collection is important because manufacturers will not reuse collected material unless it is clean and available in sufficient quantities. A bewildering assortment of different collection schemes operates in the rest of Europe, and pilot schemes are now under way in many British cities.
   A realistic target for recycling mixed refuse is somewhere between 15 and 25 percent by weight, according to researchers at the Department of Trade and Industry’s Laboratory. Statistics compiled by researchers at the University of East Anglia show that Britain could almost halve the total weight of domestic waste going to landfill by a combination of "collect” schemes(such as doorstep collections for newspapers),"bring” schemes(such as bottle banks)and plants for extracting metals.
   This estimate makes two important assumptions. One is that the government will bring in legislation to encourage the creation, of markets for products made from recycled materials, especially glass, paper and plastics. The other is that industry will continue to introduce new technology that will improve both the products and the techniques used to separate recoverable materials from mixed refuse.
Which of the following waste is best suited to recycling?
选项 A、empty milk cartons
B、textiles
C、potato peelings
D、cabbage stalks
答案A
解析  题干要求找出最适宜回收的一项，根据原文第二段一二句可知“首先要找到最好的方法将垃圾中较为清洁的材料与混合垃圾分离出来，包括玻璃容器、塑料、纸和金属在内的清洁的材料都是回收者的目标”，因此，A项“空的牛奶盒”属于纸制品，可回收，所以A正确。B项“纺织物”、C项“土豆皮”和D项“菜秆”都不属于原文所提到的回收目标。因而排除此三项，选A。
