单选题 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.

单选题 Which of the following can serve as a proper title for the passage?

【正确答案】 C

【答案解析】题干要求找出适当的标题，文章开头提到“政府提出的目标是到2010年，使英国垃圾箱内一半的可回收性材料得以回收利用。”接着“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(第二段)”同时，“研究人员还提出了较为现实的回收混合垃圾的预期目标(第三段)”。“这一目标的实现必须依靠新的技术和市场(第四段)”，根据以上论述，推断出C项为正确答案。A“一个不可能的目标”与文章开头提出的2010年目标以及多方的努力相矛盾，故排除；B项“政府的设想”是文中提到的实现回收利用的两个重要方面之一(第四段)，是细节，因而不能用来概括中心；D项“对于垃圾的分类”，文章中只提到要将垃圾的清洁的材料分离出来，而不是分类，所以错误，故选C。

【正确答案】

【答案解析】根据题干要求“在第一段中作者对于环境部长的话暗示了什么?”根据原文第二句“但是他没有给出任何为了实现这一目标的线索”，因此，B项“提出目标，但没给出方法”为正确答案。A项“创造了一个不可能的目标”这在上一题中已提到这个目标并不是一个无法实现的目标，故A错误；而C、D两项提到部长给出了清楚的信息以及给生产商的指定目标都与原文中的“No clues”相矛盾，所以排除C、D，故选B。

单选题 Which of the following waste is best suited to recycling?

【正确答案】 A

【答案解析】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。

单选题 According to the text, recycling is only possible when ______.

【正确答案】 C

【答案解析】题干“根据原文，回收利用只有在什么时候才有可能?”因此是要找出回收利用的前提条件。根据原文第二段第三句可知“清洁的材料的回收是关键，如果收集的材料不干净或数量不够多的话，生产商是不会重新利用这些材料的”，因此，C项“足够的干净材料”正确。A项“政府监督”只是回收利用的过程中的一种形式，不属于前提，故排除；B项“不同的收集方式”是方法也不是前提，所以错误；D项“少数清洁的材料”与文章中的“足够多的材料”在数量上相矛盾，故也是错误的。

单选题 What does the word "assortment” (Line 5,Par

【正确答案】

【答案解析】根据原文第二段末“在欧洲人们利用不同的收集方法回收利用，而在英国实验计划正在进行”，原文中的“A bewildering assortment of different collection schemes”就是指的不同回收利用方法的混合掺杂，所以D项“mixture”正确。A项“difference”如果放入句中，就与“different”相重复，故排除；B项“separation”表示“分离”，C项“classification”表示“分类”，这两项与句意都不相符合，因此排除。故选D。

单选题 Which of the following is not TURE according to the passage?

【正确答案】 C

【答案解析】第二段最后一句提到“pilot schemes are now under way in many British cities．”pilot在这里指的是试验性的，跟A选项中的tentative意义一致，所以A是正确的。第三段第四行中提到“Britain could almost halve the total weight of domestic waste going to landfill by a combination of‘collect’schemes”，halve指的是减半，等于“decrease…by 50%”，所以B也正确。最后一段提到的第二个设想“that industry will continue to introduce new technology that will improve both the products and the techniques…”表明实现高效的回收利用还得依靠企业跟生产商引进新的技术提高产品质量，提高可回收物质的分离技术。所以D也符合题意。选项C跟最后一段里的第一个设想相违背，故选C。
