英语高中作文 篇1
The Moon Festival, always celebrated on August 15 of the lunar calendar, is one of the most traditional of Chinese holiday. It is several hundred years old and many beautiful tales about it have been handed down from generation to generation.
On this day we eat a special kind of pastry called Moon Cake--it represents the moon and also means family reunion. It has long been a practice in our family to get together for a small moonlight party at the New Park on the evening of August 15.
Cousins and some friends sometimes join us. Sitting or lying on the soft grass, some of us chat happily and others listen to music. And amidst shouts and laughter of children chasing around excitedly, I sit quietly at a corner watching the bright, beautiful moon.

It has been over 100 years since the very first plane, invented by the Wright Brothers, flew into the sky. The first plane, which was made of wood, had only been able to fly for 12 seconds in the air, but it opened the door of the aviation world. I wonder how the Wright brothers would imagine such a magnificent idea.
They must have some kind of dream----human beings like birds, flying freely in space----they attempted various kinds of material to make planes, finally making their dream come true, although only a short 12 seconds for the first flight! We students often have different dreams: to be scientists, engineers, doctors, etc. Like the Wright brothers when they were young, we should try our best to experience different things, for example, going out of doors to watch different animals, watching butterflies in the air, or watching fish in the water. With more knowledge in these fields, we can become biologists in the future. Generally speaking, we’d better make greater efforts in our studies.
In this way, we can make our dreams come true, not only like the Wright brothers in the sky, but also like Yang Liwei in outer space.

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。
