    Global warming is the process of earth's atmosphere heating up. Over the last 100 years, the average
    temperature of earth's atmosphere has gone up 1 Fahrenheit. The weather has not changed exactly the
    same way in every area of the planet. But scientists think that the rise in average temperature is already
    affecting the earth's climate.
    Many scientists now believe that global warming is caused by cutting down trees, producing more
    trash, and polluting the environment which are some of the reasons why the temperature has gone up.
    Many scientists believe that the biggest causes of global warming are new human technologies that
    release greenhouse gases into the atmosphere.
    The greenhouse effect is not new. Certain gases in the atmosphere, like carbon dioxide, nitrous oxide
    and methane, making it hard for heat energy to go into space. In the past, the climate didn't change much
    because nature produced just the right amount of greenhouse gases to deal with it.
    Today, most scientists are pretty sure that the rising temperature can't be blamed on nature. Ever since
    the industrial revolution in the 1700s, humans have relied on machines for daily life. And many of those
    machines give off a lot of greenhouse gases. An increase in the release of greenhouse gases from human
    activities is throwing nature off balance.
    The climate is a very complicated thing, but many scientists agree that the rising atmospheric
    temperature has already damaged the environment. Sheets of ice, called glaciers, are melting in
    Antarctica and other parts of the globe. As glaciers break off and melt into the oceans, they are adding
    warm water to the oceans and causing the sea level to rise.
    Over the past 100 years, the sea level has risen 6-8 inches around the world. That means land along
    the coasts is beginning to disappear under water. Bigger and warmer oceans are also adding to other
    weather problems caused by pollution in the atmosphere. Some places have received more rain, others
    have had bigger storms and a few areas in the world have experienced unusual droughts.

    1. What is mainly talked about in this passage?

    A. The melting of glaciers.
    B. Global warming.
    C. The world's weather.
    D. The earth's temperature.

    2. What causes global warming according to scientists?

    A. Human activities.
    B. The nature itself.
    C. The earth's atmosphere.
    D. New discoveries

    3. From the passage we can see that global warming will bring about _____.

    A. the pollution in the atmosphere
    B. natural disasters
    C. population pollution
    D. the rise of glaciers

  • 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。
