英语高中作文篇1

　　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。

　　Many years ago, as the development of technology, robot was created to facilitate people’s work. Robot can do many things for men, like it will accept the order and then carry out it. The most obvious advantage of robot is to caculate very quickly. As robot gets improved all the time, its functions have been largely expanded, most people worry that it will take the place of human brains. Many movies have explored this topic and they came to the conclusion that robot will not take the place of human being. One thing for sure is that men can’t compete with robot on caculating or the computer program, but robot has no feelings, it can’t be the real person. Even it looks like a man, still it is just the machine. It is the emotion that makes the difference between man and machine.

　　许多年前，随着技术的发展，机器人被创造出来，以方便人们的工作。机器人可以为人类做许多事情，比如它会接受命令，然后执行。机器人最明显的优点是计算速度非常快。随着机器人得到不断改进，它的功能在很大程度上扩大了，大多数人担心它会取代人类的'大脑。许多电影都探讨了这个话题，他们得出结论，机器人不会取代人类的位置。有一点可以肯定的是，在计算和电脑程序方面人类无法和机器人竞争，但是机器人没有感情，不可能是真正的人。即使它看起来像一个人，它仍然只是机器。情感是区分人与机器的界限。
