　　阅读理解：

　　You can't see any objects unless light from the objects gets into your eyes. Some of the things you see give off light of their own. The sun, some stars and a lighted lamp are the examples that can be seen by their own light. But most of the things you see are not giving off light of their own. They just reflect(反射) light that falls on them from the sun or some other luminous bodies. The moon, for example, doesn't give off any light of its own. You can see it because sunlight falls on its surface and then some of the sunlight is reflected on the earth.

　　When you look at a book, it sends some of the light which falls on it to your eyes, and you see the book. If light could be kept out of where you're so that there would be no light for the book to reflect, then you couldn't see the book even with your eyes wide open. Light travels very fast and can reach us from the moon, which is about 380,000 kilometers away, in about 1.27 seconds.
