    Chemicals used for industrial processes often create dangerous forms of waste. The amount of these chemicals has risen heavily in the past few years, as more areas of the world industrialize and new products are produced. Over 80,000 different chemicals are used in industries world wide. Around the world hundreds of millions of tons of harmful waste are produced each year. Often, it is difficult and expensive to get rid of these chemicals or to store them in a way that does not endanger human life and the environment.
    Every year, major health problems result from harmful waste. Sadly, it is often when someone has died or, become seriously ill that governments will take action and reduce levels of dumped harmful waste. In 1989, a school in New Jersey had to be closed because students there had suffered too much exposure to chromium. It was later learned that large amounts of chromium had been dumped nearby and blown over to the school area.
    Research has been done to provide information on the effects of every chemical. Because waste chemicals often mix together, it will also be necessary to learn how the combinations of these chemicals affect human health.
    Some governments have realized how serious the problem is and are making laws to get rid of harmful waste. They are also trying to limit the amount of waste industries are allowed to produce.
    Not only governments but the public as well must form part of the solution. They can choose not to buy those products which require the production of harmful waste, attempt to affect policymakers, and produce less harmful waste themselves. Many scientists think that waste production can be cut. The waste can be reduced by at least one-third using existing technologies and methods.
    57.What is mainly discussed in the text?
    A The effect of every chemical.          
    B.Problems of harmful waste.
    C.Chemicals used for industrial processes.
    D.Events related to waste chemicals.
    58.From the text we know that ______.
    A.chromium can poison people when there is a wind
    B.chromium pollution makes the local government close the school
    C.Some governments don’t realize how serious the problems are until people suffer a lot from harmful waste
    D.about two-thirds of the waste can pollute the environment
    59.Which of the following least matches the solution the writer refers to?
    A.Chemicals used for industrial processes should be banned.
    B.People can make use of the existing technologies and methods to reduce the waste
    C.Policymakers make laws to limit the production of harmful waste.
    D.People choose not to buy products which may produce harmful waste.
    60.The writer of the text thinks that ______.
    A.governments should have forbidden the production of waste chemicals
    B.mixed waste chemicals can always be stored without endangering people
    C.industries must not produce waste chemicals which harm people so much
    D.everyone can do something to help solve the problem of waste chemicals

  • 健康环保类阅读

健康环保累阅读概念:

健康环保类文章常是介绍科学知识、生活常识和环境保护方面的短文。体裁有记叙文、 说明文、议论文和各种应用文。


健康环保类文章阅读技巧:

       健康环保类文章常是介绍科学知识、生活常识和环境保护方面的短文。阅读此类短文要以现象或事物为中心进行思考,理解现象产生的原因、条件和客观规律等。同时要抓住事物的特征、用途和相互关系等。科普环保类文章一般为说明文,从结构上看大致可分为三个部分:
       第一部分一般是文章的首段,主要用来提出文章的主题,即文章想要阐述、说明的主要内容;
       第二部分是文章的主体,可由若干个段落组成,对文章的主题进行展开说明;
       第三部分是结尾段,对文章的主题进行归纳总结。这类文章多用一般现在时,而且一般多使用客观性词语表述。有时为了强调客观性,也常使用被动语态。
       从近几年的考试题来看,科普环保类的文章越来越与人们的实际生活相接近。由于此类文章缺乏故事情节,很多同学对此类文章感到费解。但一般的科普类文章都是就事论事,需要逻辑推理和想象的时候较少,因此此类阅读题也没有同学们想象中的那么难,只要多加训练,就能较好地答题。
【阅读策略】
1、概要(Summarizing):
      阅完材料后,将所阅材料浓缩,摘要,做出所阅材料的书面或口头梗概。
2、组织(Organization):
      阅读后根据阅读内容,识别观点、人物、事件之间的关系以及文章的结构关系。如:时间关系、比较或对比关系、相关关系及因果关系等。
