    Experts say that agriculture provides fourteen percent of the world's greenhouse gas emissions each
    year. The gases released include carbon dioxide, a major cause of global warming.
    Twenty-one nations around the world recently joined forces to better understand and prevent
    greenhouse gas emissions from farms. The Global Research Alliance on Agricultural Greenhouse Gases
    was launched at the United Nations conference on climate change. The meeting took place in
    Copenhagen, Denmark last month.
    Agricultural experts blame a number of farm activities for producing greenhouse gases. For
    example, animal waste and cattle digestive systems release methane(甲烷, 沼气)gas. Fertilized soil
    and the burning of crop waste also release harmful gases into the air. Experts say some methods of
    farming-turning the soil to prepare for planting-also release harmful carbon dioxide.
    An official of the European Commission's Directorate General for Research says agricultural
    greenhouse gas emissions can be cut. Maive Rute suggests feeding animals a diet designed to reduce
    emissions.
    The new agricultural research group says protecting against global warming is only part of its
    purpose. It says the world also needs to develop better farming methods to feed growing populations
    in poor countries.
    United States Agriculture Secretary Tom Vilsack said no one single nation can fight agricultural
    greenhouse gas emissions and increase food production at the same time. This is why theallianceis
    important for combining resources and finding new ones.
    The United States Department of Agriculture will increase spending on farm emissions research by
    ninety million dollars over the next four years. The total will reach one hundred and thirty million dollars.
    The U. S. D. A. will share the research with other countries in the Global Research Alliance on
    Agricultural Greenhouse Gases and support researchers from developing countries that belong to the
    alliance. Money from the Borlaug Fellowship Program will let the researchers study agricultural climate
    change with American scientists.
    Mister Vilsack said that just as climate change has no borders, there should be no borders for
    research.
    1. In Paragraph 4, Maive Rute recommends __________.
    A. increasing food production
    B. changing cattle digestive systems
    C. developing better farming methods
    D. giving animals the food meant to produce fewer emissions
    2. The underlined word "alliance" in Paragraph 6 probably means __________.
    A. action or state being joined together
    B. an agreement signed between countries
    C. a program or project set up for a research
    D. an organization formed for different goals
    3. How much has the U. S. D. A. spent on farm emissions research so far?
    A. 130 million dollars.
    B. 220 million dollars.
    C. 40 million dollars.
    D. 90 million dollars.
    4. The purpose of the passage is to __________.
    A. suggest a total ban on farm activities
    B. introduce the Copenhagen conference held last month
    C. appeal to more countries to cut agricultural emissions
    D. inform readers of the major cause of global warming

  • 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。
