问题     Read the following article about responsibility for the natural environment and the questions on the opposite page.
    For each question(15-20), mark one letter(A, B, C or D)on your Answer Sheet.
    The difficulty of balancing profits and social responsibility is very apparent when you consider environmental issues. Consumers value the goods and services that business produces, but businesses cannot produce goods and services without polluting to some degree. Businesses strive to lower their costs in order to offer products to consumers more efficiently and to make profits for investors, but sometimes it is necessary for businesses to spend more in order to pollute less. When such situations arise, whose interests should be served first—those of society, the consumer, or the investor? Clearly, this question has no easy answer, but examining how businesses pollute may provide some perspectives.
    Economic progress threatens our air, water, and land because these elements can so easily be tainted by pollution. Moreover, the pollution in any one element can easily taint the others. This problem is pervasive in industrialised and developing nations alike. In fact, the emerging economies of Asia and Latin America have built much of their growth on very loose environmental standards. But Mexico, Malaysia, and other countries are realising that their prosperity can be sustained only if their citizens can enjoy a quality of life that comes with a clean environment. At the same time, the countries of Eastern Europe are scrambling to reverse the decade of environmental neglect that occurred around the middle of the 20th century. As you can imagine, this is no easy task.
    The most noticeable form of air pollution, smog, is produced by the interaction of sunlight and hydrocarbons(gases released when fossil fuels are burned). We need only look at the smog that hangs over many major cities of the world to know that air pollution is a problem that businesses, consumers, and governments must address together. Another damaging air pollutant is acid rain, created when emissions from coal-burning factories and electric utility plants react with air. In addition, emissions from factories and cars pollute the air and contribute to global wanning through the greenhouse effect, in which heated gases form a layer of unusually warm air around the earth, trapping the sun’s heat and preventing the earth’s surface from cooling.
    Experts worry about airborne toxins that are emitted during some manufacturing processes. Large and small companies together release millions of pounds of chemical wastes into the air each year. Although the effects of many of these substances are unknown, some are known to be cancer causers. Of special concern in recent years are microscopic particulates in the air that may be responsible for more than 150, 000 deaths each year.
    Our air is not the only part of our environment to suffer. Water pollution has damaged many U. S. lakes, rivers, stream, harbours and coastal waters. This pollution comes from a variety of sources: manufacturing facilities, mining and construction sites, farms, and city sewage systems. The main threat is the careless day-to-day disposal of wastes from thousands of individual sources. Even if all wastewater were purified before being discharged, our groundwater would still be endangered by leakage from the millions of tons of hazardous substances that have been buried underground or dumped in improper storage sites. Much of this pollution was created years ago by companies that carelessly—but legally—disposed of substances now known to be unhealthy. Cleaning up these wastes is extremely difficult and expensive.
    In addition, companies and individuals generate enormous amounts of solid waste—over 200 million tons in the United States each year. Much of this waste ends up in landfills. A large part of the problem is consumer demands for convenience and fashion. These demands lead to creating disposable items, manufacturing products with excess packaging, and discarding useful items that are no longer the hot style or colour. Fortunately, recent efforts to conserve and recycle resources are helping to combat the land pollution problem. [br] What is the tone of this passage?
选项 A、optimistic
B、pessimistic
C、subjective
D、objective
答案 D
解析 第六段讲述了固体废物，仅美国一个国家每年就有超过两亿吨的固体废物，这些废物大部分会被填埋在垃圾场。产生这么多固体废物的原因是消费者追求便捷与时尚。为了满足消费者需求，生产商就会生产用完即可丢弃的产品，给产品过度包装。消费者对样式或颜色不时髦但仍有用的东西随即丢弃。幸运的是，最近人们开始致力于资源的加工再利用，缓解了土地污染的问题。题目问及整篇文章的语气。文章大部分篇幅陈述事实，并以数字、举例等形式加以说明，据此可判断，作者的语气是客观的，即D项为正确选项。
