In recent years many countries of the world have been faced with the problem of how to make their workers more productive. Some experts claim the answer is to make jobs more varied. But do more varied jobs lead to greater productivity? There is evidence to suggest that while variety certainly makes the workers' life more enjoyable, it does not actually make him work harder. As far as increasing productivity is concerned, the variety is not an important factor. Other experts feel that giving the worker freedom to do his job in his own way is important and there is no doubt that this is true. The problem is that this kind of freedom cannot easily be given in the modern factory with its complicated machinery which must be used in a fixed way. Thus while freedom of choice may be important, there is usually very little that can be done to create it. Another important consideration is how much each worker contributes to the product he is making. In most factories the worker sees only one small part of the product. Some car factories are now experimenting with having many small production lines rather than one large one, so that each worker contributes more to the production of the cars on his line. It would seem that not only is the degree of workers' contribution an important factor, therefore, but it is also one we can do something about.To what extent more money led to greater productivity? The workers themselves certainly think this is important. But perhaps they want more money only because the work they do is so boring. Money just lets them enjoy their spare time more. A similar argument may explain demands for shorter working hours. Perhaps if we succeed in making their jobs more interesting, they will neither want more money, nor will shorter working hours be so important to them.

Eclipse is a word meaning hide. When the moon passes in front of the sun, the sun is hidden from us, and we call that an eclipse of the sun. When the moon becomes hidden in the earth's shadow, we call that an eclipse of the moon. An eclipse of the sun happens in daytime when the moon is new and on the same side of the earth is the sun. Even though the moon is much smaller than the sun, the moon is closer to earth, so it can completely block off the sun. This is called a total eclipse. People in certain areas on earth see a black disc in the sky. It has a beautiful halo of light around it. When the moon is not directly between the sun and the earth, it darkens only part of the sun, causing a partial eclipse. An eclipse of the moon happens at night when the moon is full. The earth has a shadow, just like everything else the sun shines on. This shadow stretches out into space on the side of the earth away from the sun. If the moon moves completely into this shadow, the eclipse is total. Then people on earth see something very strange. The whole moon turns deep red. A partial eclipse will happen if the moon moves only partly into the earth's shadow.Long ago people were afraid of eclipses. They didn't like the strange darkness caused by them. They thought it was caused by a dragon trying to eat up the sun. These people shot arrows into the air and beat drums. In this way they hoped to scare away this beast. Other people would urge dogs to howl in order to frighten away bad spirits. Eclipses, however, have really been quite helpful. Much has been learned from them. During one in 1868 scientists discovered helium, the gas that makes balloons rise. Another eclipse allowed scientists to record the very hot temperatures of the outer parts of the sun. Also, the belief that the sun's pull caused light from other passing stars to turn rather than go in a straight line was proved during an eclipse. The world continues to learn exciting facts from eclipses.

The balance of nature is not an empty phrase. Nature provides a population to occupy a suitable environment and cuts down surplus population to fit the available food supply. One means of reducing surplus population is predators(食肉动物); others are parasites(寄生虫) and diseases. Also, population density produces nervous disorders and even drivers animals to mass migrations, like the lemmings(旅鼠) of Norway who plunge(跳入) into the sea.That predators populations increase to control other animals has long been known. Many years ago, the Hudsons Bay Company records revealed that the fox population went up and down about a year after the rabbit population had gone up and down.Sometimes a situation occurs in which the predator population is reduced to a level below that which nature can readily replace. On Valcour Island in Lake Champlain (New York), a costly campaign resulted in the elimination of predatory animals only to have birds and small animals (including grouse(松鸡) and hares, popular game) increase for four years afterward. Then, lacking predator control, nature resorted to disease to cut down these populations. Jamaica had an example of natures persistence in providing animals for existing habits. Sugar planters, about 75 years ago, imported mongooses(猫鼬) to control rats. The mongooses killed off the rats and, with plentiful food, multiplied. Rats became scarce and the mongooses ate lambs, kids, puppies(小狗)，and wildlife. Eventually, food became scarce and the mongooses population declined.

People became quite illogical when they try to decide what can be eaten and what cannot be. If you lived in the Mediterranean, for instance, you would consider octopus a great delicacy. You would not be able to understand why some people find it repulsive. On the other hand, your stomach would turn at the idea of frying potatoes in animal fatthe normally accepted practice in many northern countries. The sad truth is that most of us have been brought up to eat certain foods and we stick to them all our lives. No creature has received more praise and abuse than the common garden snail. Cooked in wine, snails are a great luxury in various parts of the world. There are countless people who, ever since their early years, have learned to associate snails with food. My friend, Robert, lives in a country where snails are disliked. As his flat is in a large town, he has no garden of his own. For years he has been asking me to collect snails from my garden and take them to him. The idea never appealed to me very much, but one day, after a heavy shower, I happened to be walking in my garden when I noticed a huge number of snails taking a walk on some of my prize plants. Acting on a sudden impulse, I collected several dozen, put them in a paper bag, and took them to Robert. Robert was delighted to see me and equally pleased with my little gift. I left the bag in the hall and Robert and I went into the living room where we talked for a couple of hours. In had forgotten all about the snails when Robert suddenly said that I must sta奥鹏华中师范大学平时在线作业y to dinner. Snails would, of course, be the main dish. I did not fancy the idea and I reluctantly followed Robert out of the room. To my surprise, we saw that there were snails everywhere: they had escaped from the paper bag and had taken complete possession of the hall! I have never been able to look at a snail since then.

Language learning begins with listening. Individual children vary greatly in the amount of listening they do before they start speaking, and late starters are often long listeners. Most children will obey spoken instructions some time before they can speak, though the word obey is hardly accurate as a description of the eager and delighted cooperation usually shown by the child. Before they can speak, many children will also ask questions by gestures and by making questioning noises.Any attempt to trace the development from the noises babies make to their first spoken words leads to considerable difficulties. It is agreed that they enjoy making noises, and that during the first few months one or two noises sort themselves out as particularly indicative (标示的) of delight, distress, sociability, and so on. But since these cannot be said to show the babys intention to communicate, they can hardly be regarded as early forms of language. It is agreed，too，that from about three months they play with sounds for enjoyment, and that by six months they are able to add new sounds to their store. This self-imitation (自我模仿) leads on to deliberate imitation of sounds made or words spoken to them by other people. The problem then arisen so to the point at which one can say that these imitations can be considered as speech.It is a problem we need not get out teeth into. The meaning of a word depends on what a particular person means by it in a particular situation; and it is clear that what a child means by a word will change as he gains more experience of the world. Thus the use, at say seven months, of mama as a greeting for his mother cannot be dismissed as a meaningless sound simply because he also uses it at other times for his father, his dog, or anything else he likes.Playful (顽皮的) and apparently meaningless imitation of what other people say continues after the child has begun to speak for himself. I doubt, however, whether anything is gained when parents cash in on this ability in an attempt to teach new sounds.
