1.The Nature of Light光的性质?Many years ago, if we looked in a dictionary, we would find that light was described as the opposite of darkness.????许多年前，我们打开词典就会发现，光被解释为黑暗的反义词。?Today scientists tell us that light is a form of energy that radiates or gives off rays just as a pebble creates waves if we dropped it into a pond of water.(如何翻译长的定语？）今天，科学家告诉我们说，光是能的一种形式，光能够辐射或者放出光线，就像我们将一块小石头投入水中时在水面上激起波浪一样。?These rays, or light waves, as they are sometimes called, can travel through space and certain kinds of materials.这些光线，即人们有时所说的光波，能够穿过空间及某些种类的材料。?Light waves that reach and enter our eyes produce a sensation that we call sight.???到达并进入我们眼睛的光波，能够产生一种我们叫做视觉的感觉。?Light is our guide to the world around us.光是我们认识周围世界的向导。?Because of light we can see our way around our homes; we can see to walk through streets; we can see the sky and we can even read this book.由于有了光，我们能够看得见我们家园的道路；我们能够看得见，因而能够在街上走；我们能够看得见天空，甚至能够读这本书。?If you closed your eyes, you would not see this page because your eyelids would prevent the light rays from entering your eyes.如果你闭上眼睛，就会看不到这一页，因为你的眼皮会阻止光线进入你的眼睛。?Thus, we have established one fact about light: unless the light from an object enter our eyes, we can not see the object.我们由此而肯定了有关光的一个事实：只有当一个物体射来的光进入我们眼睛的时候，我们才能看到该物体。（反译）?Some objects, like the sun, stars and the electric bulb give off their own light.有些物体，如太阳、星星和灯泡，自身能够发光。?They radiate light because they are very hot, or as scientists call them, red-hot and white-hot bodies.它们之所以能够发光，是因为它们是一些非常热的，或者正如科学家们所说，赤热的和白热的物体。?The light waves they radiate are known as incandescent light.(incandescent:?白热的，白炽的)它们所射出的光波叫做白炽光。?Most of the light we receive is from the largest source of incandescent light – the sun.我们接收到的大部分光都是来自最大的日光源——太阳。?Another source of light is produced by electric sparks in tubes containing special gases; that is known as fluorescent or cold light.另一种光源是由电火花在含有特殊气体的管子中产生的；这种光叫做荧光或冷光。?The light we see directly from the source of light, such as the sun, an electric bulb or a fluorescent?lamp,?is
