    Light travels at a speed which is about a million times faster than the speed of sound. You can get some idea of this difference by watching the start of a race. If you stand some distance(距离) away from the starter, you can see smoke from his gun before the sound reaches your ears.
    This great speed of light produces some strange facts. Sunlight(太阳光) takes about 8 minutes to reach us. If you look at the light of the moon tonight, remember that the light rays left the moon 1.3 seconds before they reached you. The nearest star is so far away that the light that you can see from it tonight started to travel towards you four years ago at a speed of nearly 2 million km. per minute. In some cases, the light from one of tonight’s stars had started on its journey to you before you were born.
    Thus, if we want to be honest, we can’t say, “The stars are shining tonight.” We have to say instead, “The stars look pretty. They were shining four years ago, but their light has only just reached the earth.”
    小题1:Light speed is ______ sound speed.
    A.as fast as
    B.a million times slower than
    C.about millions of times faster than
    D.about a million times faster than
    小题2: If you stand 200 meters away from a man who is firing a gun to start a race, you will find out that ______.
    A.you can hear the sound before you see the smoke
    B.the sound does not travel as fast as light
    C.the sound will reach you before the man fires
    D.sound travels about a million times faster than light
    小题3:Sunlight obviously(显然的) ______ than the light of the moon.
    A.has to travel a greater distance
    B.moves less quickly
    C.travels much more quickly
    D.is less powerful
    小题4: The scientific way of saying "The stars are shining tonight" should be ______.
    A.the stars have been shining all the time
    B.the stars seen tonight will shine four years later
    C.the stars were shining long ago but seen tonight
    D.the starlight seen today could be seen four years ago

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。
