Evolution of Sleep
there is some evidence that the two types of sleep, dreaming and dreamless, depend on the life-style of the animal, and that predators are statistically much more likely to dream than prey, which are in turn much more likely to eperience dreamless sleep. in dream sleep, the animal is powerfully immobilized and remarkably unresponsive to eternal stimuli.
dreamless sleep is much shallower, and we have all witnessed cats or dogs cocking their ears to a sound when apparently fast asleep. the fact that deep dream sleep is rare among prey today seems clearly to be a product of natural selection, and it makes sense that today, when sleep is highly evolved, the stupid animals are less frequently immobilized by deep sleep than the smart ones. but why should they sleep deeply at all? why should a state of such deep immobilization ever have evolved? perhaps one useful hint about the original function of sleep is to be found in the fact that dolphins and whales and aquatic mammals in general seem to sleep very little. there is, by and large, no place to hide in the ocean. could it be that, rather than increasing an animals vulnerability, the function of sleep is to decrease it? wilse webb of the university of florida and ray meddis of london university have suggested this to be the case. it is conceivable that animals who are too stupid to be quiet on their own initiative are, during periods of high risk, immobilized by the implacable arm of sleep. the point seems particularly clear for the young of predatory animals. this is an interesting notion and probably at least partly true.
睡眠的进化
睡眠是古老的。 从脑电图上看，我们人类和所有灵长目动物以及几乎所有的哺乳动物和鸟类都一样需要睡眠;甚至爬行类动物也有睡眠。
有证据显示，有梦睡眠和无梦睡眠这两种类型的睡眠取决于该动物的生活方式。 从统计上看，食肉动物比被捕食动物有更多的有梦睡眠，而被捕食动物更多地无梦睡眠。 动物在有梦睡眠时，被有效地解除动作能力，并且对外界刺激缺乏反应。 无梦睡眠则要浅得多。 我们都看到过猫和狗在显然的`酣睡中，有一点响动耳朵就会竖起来。 被捕食动物很少有深度的有梦睡眠，这看来显然是自然选择的结果。 而且这一点是有道理的：当睡眠高度进化以后，愚笨的动物比聪明的动物更少在深度睡眠状态下丧失动作能力。 但是动物为什么要进入深度睡眠呢?为什么这样的无动作状态也会进化出来呢? 海豚、鲸鱼以及水生哺乳动物睡眠都极少，这一事实可以给睡眠的根本功能提供有用的线索。 海洋中是没有藏身之处的。 会不会是这样，睡眠不但不增加动物受伤害的可能性，反而是减少了这种可能性呢?佛罗里达大学的wilse webb和伦敦大学的ray meddis认为情况就是如此。 可以想像得出，在危险的时刻，那些由于太愚笨而不能自动保持安静的动物，会不由自主地变得动弹不得。 这一点在食肉动物的幼兽身上表现得特别明显。 这是一个很有意思的看法，它至少部分是正确的。
英语高中作文 篇3
We live in the world every day. We eat food, drink water, wear clothes, watch TV,use computers and so on. We are producing waste every moment.Generally speaking, there are four sorts of waste. They arematerial waste, organic waste, inorganic waste and poisonous & harmful waste. Now, we are going to talk about each sort ofwaste one by one.Material waste: it means the waste of substance or things from which something else can be made. Forexample, people throw away the used metal products and buy a new one, so the old metal waste accumulates.
At last, theybecome waste. For example, when people finish reading newspaper, the paper will become waste. When the glass is broken, italso becomes waste. Nobody wants to use a broken window or drink with a broken glass or wear a pair of broken glasses. Onceit is broken, it becomes waste. The rate of using plastics is increasing day by day. People use plastic bags because they areconvenient. When they get home, they throw the plastics way, paying no attention to the environment. The more convenienceplastics brings to us, the more plastic waste is produced. This is called “white pollution” as most plastics are white.Some of our products we use every day are made of rubber, just like the tyres and the bottom part of our shoes. It’s truethat rubber plays an important role in our life. However, it also brings us some trouble when it has been used for a longtime and becomes old. The old tyres become waste because it can’t break down by nature. This is really a big problem.Organic waste: it refers to waste from living things, including waste from animals, plants and people. Some parts ofvegetables are thrown away as waste because they don’t taste good. In the past, people cooked their food using burning coal,so there left the burned coal, which is useless, like the thrown vegetables. All this sorts of waste contain organism, so itis called organic waste.Actually, we also have inorganic waste, the opposite to organic waste, including building waste,broken pottery and china, and cinder.The last part is harmful and poisonous waste, such as used batteries, electricalapparatus and medical supplies. Computers and TV sets are one part of electrical apparatus.
You see, the old electricalapparatus can set off some dangerous rays and make the soil harder, even damage the under ground water. Mobile phones are asdangerous as computers and TV sets. As we know, X-rays can be used to examine patients, but the X-rays machines are dangerouswhen they are thrown away without any treatment. They can’t be used to treat the sick, but they still can give off rays. Forthe normal people, they can be dangerous. So, we must think about this problem. As waste has four sorts, we can sort theminto each sort that they belong to. It’s convenient to treat them after they are sorted. Then we can deal with them sort bysort. We have thought out some methods like storing them in order to change them into plant food, or burning them in a hugestove and use the heat to make electricity. For the first way, the change rate is much too low and it may pollute the underground water. For the second one, of course it’s wonderful if it’s easy to be tried out. But to build such a huge stovewill cost too much. Not a good method. Now you see, treating waste is not an easy job.
