    When the Audet family turns on the lights at Blue Farm, they are using electricity that comes from cows—cow manure (粪肥), to be specific.
    Cows produce a lot of wastes. One cow can create 30 gallons of wastes each day. Now imagine the output of over 1,000 cows at Blue Farm. That’s really a big amount.
    When farmers clean their barns, they put the wastes in a big heap, and spread some of them on their fields for fertilizer(肥料). But now places like Blue Spruce Farm have a new way of using cow wastes. They use them to produce electricity.
    Here’s how it works: A big machine moves back and forth cleaning the barn floor. “The cows aren’t bothered,” says Marie Audet. “They are animals of habit; they get used to it, and just lift one foot and then another to let it go by.”
    The machine pushes the manure into a big 600-gallon tank like a small swimming pool. The tank is called a digester (化粪池) because what happens there is just like what happens inside a cow: Bacteria(细菌) get to work and continue to digest the manure.
    Methane gas (甲烷、沼气)in the atmosphere is known as a “greenhouse” gas because it keeps heat just like a greenhouse does, causing our planet to warm up. That’s an environmental concern. But the digester has a good result. Its gas is kept and used to power electric generators (发电机).
    At Blue Farm, the generators make enough electricity to power 400 homes. The Audet family sells the extra electricity they can’t use themselves.
    小题1:We learn from the text that the Audet family is using cow wastes to ______.
    A.make electricity B.produce fertilizerC.build their farm D.feed the cows
    小题2:How are the cow wastes collected into the digester at Blue Farm?
    A.Marie Audet does the workB.The job is done by machine
    C.The cows lift the cow wastesD.Bacteria get to work on them
    小题3: According to the passage, which of the following is changed into electricity?
    A.The power of moving water. B.The heat of burning coal.
    C.The power of sunlight.D.The heat of the methane gas
    小题4:The new way of using cow wastes at Blue Farm might be best described as ______.
    A.reducingB.savingC.recyclingD.changing
    小题5: What is the main purpose for writing the passage?
    A.To introduce a new way of making electricityB.To explain how a new energy works better
    C.To show a new rebuilding plan for a big farmD.To explain the reasons for green house effect

等考点的理解。关于这些考点您可以点击下面的选项卡查看详细档案。
  • 科教类阅读
  • 健康环保类阅读
科普类的阅读:
科普类的阅读理解包含介绍科学知识、社会知识的短文。阅读这类短文时,要以事实为中心进行思考,抓住事物的特征、用途、相互关系等。
如果是介绍社会现象的文章,要掌握所谈现象的内涵。
答题技巧:
1. 加强整体意识,把握文章的主要内容。在阅读的时候可给段落标上序号,并给重要的句子和
   关键词做上记号,尤其是各段中心句,为答题提供更快捷更多的信息源。
2. 审清题干,发觉和把握试题中有效的提示性信息,确认命题的角度、阅读范围和答题方式。
3. 定位阅读,强化对应意识。同时要注意原文利用和自我加工相结合。
健康环保类阅读:
本类型主要是围绕饮食健康、医疗卫生及环境保护等方面选取实际的材料来设题。
体裁有记叙文、说明文、议论文和各种应用文。
健康环保类阅读题答题注意事项和技巧:
应试生态环保类题目时,在理解文章的基础上,要重点突破——归纳主旨大意技能,因为推断是以整体理解为基础的推断能力。
1.归纳主旨大意:
(1)寻找具体段落的中心思想的方法是:找出每小段的主题句。
主题句通常有这样的特点:
①有一个话题(topic);
②有阐述控制性概念,偶尔也可在一段中间;
③有的文章无明显主题句,主题句隐含在段意之中。这就需要读者进一步加工概括了。
(2)寻找整篇文章的中心思想的方法建立在寻找具体段落中心的基础上的。
应观察全文的结构安排,理解文章浓墨重笔写的“重心”,考虑文章组织材料及支撑性细节是服务于什么的,分析故事的发展结局都是围绕什么中心大意来安排的。
(3)典型错误:
①忽视文章的结构;
②混淆了中心与支撑细节或材料的区别;
③忽视文章表意的倾向性;
④漏掉了主要的特征词。

2.正确推理判断:
推理判断试题要求考生尽量考虑文中全部信息或事实,在通篇理解文章的基础上领会作者的言外之意,并作出正确的推理和判断。
(1)数据推断题
解答此类题,关键是要善于捕捉有关数字的信息,然后在透彻理解原文的字面意义和题意的基础上,运用自己的数学知识,对其进行分析、推算,从而得出正确的结论。
(2)知识推断题
根据文章中所阐述的细节,运用基础知识进行分析、推敲,从而得出符合文章原义的结论的一种推断方法。
(3)逻辑结论推断题
根据事实、论点、例证等一系列论据材料,不是根据自己的经验、态度、观点或爱好去理解文章的内涵。
解答这类题的前提是要首先获得短文的主题思想或列举的具体事实,然后按题意要求进行推断。
(4)对作者态度、倾向的推断题
作者的倾向和感情往往隐含在文章的字里行间,或流露于修饰的词语之中,因此,在推断过程中,应特别注意文中作者的措辞。
