You can see even more with a telescope (望远镜). And you might also see many larger stars and some really “red or blue” ones. The bigger the telescopes are, the more objects and details you will see in the sky.But scientists believe there are some things, so-called black holes, in the sky that we will never see, even with the biggest telescope on the clearest night. They're the mysterious dead stars.It is hard to imagine that stars die. After all, our Sun is a star. Y ear after year we see it up in the sky, burning brightly，giving us heat and light，which certainly doesn't seem to be getting old or weak. But stars do burn out and die after billions of years.As a star's gases burn, they give off light and heat. But when the gas runs out, the star stops burning and begins to die. As the star cools, the outer layers of the star pull in toward the center. The star wascrushed (挤压) into a smaller and smaller ball. If the star was very small，it ends up as a cold, dark ball called a black dwarf (矮星)．Imagine if the Earth was crushed until it was the size of a small ball. That's how tightly this dead star，a black hole, is packed. Its gravity attracts in everything — even light, which can never come back to your eyes. That's why you see nothing but blackness.So the next time you stare up at the night sky, remember: there's more in the sky than meets the eye! In the silent darkness are black holes — the great mystery of space.1．The passage mainly tells us something about ________.A. the night skyB. the telescopeC. the black holesD. the gravity答案与解析C文章开篇描述夜空中有点点的繁星，然后指出用望远镜会看到更多的星星，但还是有一些看不见的“黑洞”，借此引出主题。
