Researchers have found that migrating animals use a variety of inner compasses to help them navigate. Some direct themselves by the position of the sun. Others navigate by the stars. Some use the sun as their guide during the day, and then switch tn star navigation by night. One study shows that the homing pigeon uses the Earth's magnetic fields as a guide in finding its way home, and there are indications that various other animals, from insects to mollusks, can also make use of magnetic compasses. It is of course very useful for a migrating bird to be able to switch to a magnetic compass when clouds cover the sun; otherwise it would just have to land and wait for the sun to come out again.Even with the sun or stars to guide by, the problems of navigation are more complicated than they might seem at first.

1.根据牛顿的发现, 白光是所有可见光叠加而成的。这就是加色概念的典型例子。例如去掉蓝色色调, 白光就会变为黄色, 还有其他例子等等。然而当把颜料的所有颜色混合, 我们会得到黑色, 这就是典型的减色理论, 黑色代表所有颜色都存在。加色是透射光的领域的概念, 减色是色素、染料和化学品的领域的概念。2.但是我们对创新的追求究竟是为了实现什么呢?创新就是一种重要的新产品或者新程序, 或者是一项制度, 能够在实际生活中大范围的应用, 对经济和社会有着革命性的意义, 就是以更低成本实现更高的工作效益。遗憾的是我们现在几乎把一切事情都用创新来形容, 因为不是所有创新都能给社会财富的増长和生活的改善提供一个长久的平台。3.睡眠问题研究者发现, 总的来说, 大多数人都是随着年龄的增加, 睡眠问题却越来越少, 上了年纪的人反而对失眠有更好的承受力。睡眠模式的大多改变都发生在20岁到60岁之间。那些经历着睡眠问题的人, 应该去看医生才好。因为他们经历的问题也许是某种生病的迹象, 也许是一些药物的副作用。

When he was so far out that he could look back not only on the little bay but past the stretch of rock that was between it and the seashore, he floated on the warm surface and looked for his mother. There she was a little yellow dot under an umbrella that looked like a piece of orange-skin. He swain back to shore, relieved at being sure she was there, but all at once very lonely.On the other side of the bay was a loose scattering of rocks. Shove them, some boys were stripping off their clothes. They came running, their bodies bare down to the rocks Jerry swam towards them and kept his distance a little way off. They were off that coast, all of them burned smooch dark brown and speaking a language he did not understand. To be with them, of them was a feeling that filled his whole body. He swam a little closer, they turned and watched him with narrowed, attentive dark cues. Then one smiled and waved. It was enough. In a minute he bad swum in and was on the rocks beside them, smiling with extreme nervousness. They shouted cheerful greetings at him, and then, as he preserved his nervous, puzzled a mile. They understood that he was a foreigner who had wandered from his own part of the sands, and they promptly forgot him. But he was happy. He was with them.They began diving again and again from a high point into a well of blue sea between rough, pointed rocks. After they had dived and come up, they swam round pulled themselves up, and wailed their turn to dive again. They were big boys-men to Jerry. He dived and they watched him, and when he swam round to lake his place, they made way for him. He felt he was accepted, and he dived again, carefully, proud of himself.Soon the biggest of the boys balanced himself, shot down into the water, and did not come up. The others stood about watching Jerry, after waiting for the smooth brown head to appear, let out a cry of warning; they looked at him idly and turned their eyes back towards the water. After a long lime, the boy came upon the other side of a big dark rock, letting the air escape suddenly from his lungs with much coughing and spiting, and giving a shout of satisfaction. Immediately, the rest of them dived in. One moment the morning seemed full of boys as noisy as crowd of monkeys, the next, the air and the surface of the water were empty. But through the heavy blue, dark shapes could be seen moving and searching.Jerry dived, shot past the school of underwater swimmers, saw a black wall of rock towering over him touched it, and shop up at once to the surface, where the rock formed a low wall be could tee across. There was no one in sight; under him, in the water, the shadowy shapes of the swimmers has disappeared. Then one and then another of the boys came up on the far side of the wall of rock, and he understood that they had swum through some gap or hole in it. He dived down again. He could see nothing through the stinging salt water but the solid rock. When he came up, the boys were all on the diving rock, preparing to attempt the track again. And now, overcome with a sense of failure, be shouted up in English: “Look at me !’’ and he began splashing and kicking in the water like a foolish dog.
