    Thousands of years ago，in Egypt，the children's favorite game was throwing stones． But a badly thrown stone could hurt a child． Looking for something less dangerous to throw，the peo-ple in Egypt made the first balls．

    At first，they used tree leaves to make balls． They used vines(藤) to keep the leaves to-gether． Later they began to use pieces of animals' skin and filled them with some light things．These balls were much better than the old ones．

    Before long they invented a lot of ball games，and each had its own rules． They began to play these ball games according to the rules． They thought that ball playing was one of the best ways to teach the young men to be brave and strong．

    Learn About Light

    1 Ancient civilizations were amazed by the existence of light for thousands of years?The Greek philoso-
    phrrs believed that light was made up of countless,tiny particles that enter the human eye and create what
    we call vision.However,Empedocles and a Dutch scientist named Christian Huygens believed that light wag
    like a wave.According to them,light spread out and travelled like a straight line.This theory was accepted
    during the 19th century.
    2 In 1905,Albert Einstein published a research paper in which he explained what is referred to as the
    photoelectric effect.This theory explains that particles make up light.The particles Einstein was referring to
    are weightless bundles（束）of electromagnetic（电磁）energy called photons（光子）.Today,scientists agree
    that light has a dual（二重）nature一it is part particle and part wave. It is a form of energy that allows us to
    see things around us.
    3 Things that give off light are known as sources of light.During the day,the primary source of light is
    the sun.Other sources of light include stars,flames,flashllights,street lamps and glowing gases in glass
    tube.
    4 When we draw the way light travels we always use straight lines.This is because normally light rays
    travel in a straight line.However,there are some instances that can change the path and even the nature of
    light. They are reflection,absorption,interference（干扰）,etc.
    5 Physicists have attempted to measure the speed of light since the early times.In 1849,Hippolyte
    Fizeau conducted an experiment by directing a beam of light to a mirror located kilometers away and placed
    a rotating cogwheel（旋转齿轮）between the beam and the mirror. From the rate of rotation of the wheel,
    number of wheel'S teeth and distance of the mirror,he was able to calculate that the speed of light is 313
    million meters per second.In a vacuum（真空）,however,the speed of light is 299,792,458 meters per
    second.This is about a million times faster than the speed of an airplane.

    Objects are visible to the human eye as light is_______.
    A:sources of light
    B:the speed of light
    C:the path of light
    D:a straight line
    E:a beam of light
    F:a form of energy

    答案：F
    解析：
    第二段前半部分介绍了爱因斯坦的光电效应理论，后半部分则介绍了现代科学家对于 光的看法：他们认为光具有二重性。
    第三段主要讲述了光源的定义和常见的光源，故选B。
    第四段主要讲述了光的传播方式以及影响光的传播方式和性质的因素，故选D。
    第五段以Flippolvte Fizeau为例，介绍了物理学家是如何测定光速的，故选C。
    文章第一段中只提到光像一条直线一样传播，而并非说光是一条直线。另外，由第二段 最后一句话“it is a form of energy that allows us to see things around us.”可知，光是一种能让我 们看到周围事物的能量，故选F。
    山第三段的最后一句话“Other sources of light include stars, flames, flashlights, street lamps and glowing gases in glass tube.”可知，应选A。
    由第四段最后两句话可知，一些因素会影响光的传播路径，这些因素包括光的反射、光 的吸收和光的干扰，故选C。
    由第五段的实例可知,Hippolyte Fizcau是用一束光测出了光的速度，故选B。第4部分；阅读理解第一篇 本篇文章主要讲述了石墨烯对于将未电子学发展的重要性以及人们可用一种简单的方式发 现石、墨烯。

    Paragraph 5______
    A: How Is the Nature of Light Explained Today?
    B: What Are Sources of Light?
    C: How Did Physicists Measure the Speed of Light?
    D: How Does Light Travel?
    E: How Did People Think of Light Years Ago?
    F: What Causes a Shadow?

    答案：C
    解析：
    该概括大意与完成句子所选的阅读材料为记述文，段落主题相对于论述文而言较松散，因此记述文中的段落大意往往需要考生根据自己的理解而归纳概括出来。解答概括大意题的技巧往往派不上用场。第二段主要讲述现代科学家认同了爱因斯坦的光电效应理论。因此可以判断A选项“当今人们如何解释光的性质”正确。
    第三段第一句“Things that give off light are known as sources of light.”就点明主旨，发光的物体是光源。所以B选项“什么是光源？”正确。
    第四段主要讲述光传播的问题，所以D选项“光是如何传播的”正确。
    第五段的关键字是speed of light，光速。所以C选项“物理学家如何测量光的速度”正确。
    题干意为“人们可以看见物体是因为光……。“从第二段最后一句可知，人们看见物体是因为光是一种能量。所以F项a form of energy正确的。
    题干意为“星星、火焰、手电筒都是……的例子。”第三段“Other sources of light include stars , flames , flashlights...”说明，这些都是光源的例子。所以A选项sourcesof light是正确的。
    题干意为“某些情况下，如反射和吸收可以改变……。”第四段中“there are some instances that can change the path and even the nature of light.They are reflection,ab-sorption , interference , etc.”这说明有一些情况可以改变光的路径。所以C选项the path of light是正确的。
    题干意为“Hippolyte Fizeau做了一个刚试……的实验。”文中最后一段 “Hippolyte Fizeau conducted an experiment by directing a beam of light to a mirror...he was able to calculate that the speed of light...”可知Hippolyte Fizeau通过实验计算出了光速。所以B选项是正确的。
