新概念三47课课文Too high a price?Pollution is the price we pay for an overpopulated, over -industrialized planet. When you come to think about it, there are only four ways you can deal with rubbish: dump it, burn it, turn it into somethingyou can use again, attempt to produce less of it. We keep trying all four methods, but the sheer volume of rubbish we produce worldwide threatens to overwhelm us.Rubbish, however, is only part of the problem of polluting our planet. The need to produce ever - increasing quantities of cheap food leads to a different kind of pollution. Industrialized farming methods produce cheap meat products: beef, pork and chicken. The use of pesticides andfertilizers produces cheap grain and vegetables. The price we pay for cheap food may be already too high: Mad Cow Disease (BSE) in cattle, salmonellain chicken and eggs, and listeria in dairy products. And if you thinkyou'll abandon meat and become a vegetarian, you have the choice of very expensive organically - grown vegetables or a steady diet of pesticides every time you think you're eating fresh salads and vegetables, or just having an innocent glass of water!However, there is an even more insidious kind of pollution that particularly affects urban areas and invades our daily lives, and that is noise. Burglar alarms going off at any time of the day or night serve onlyto annoy passers - by and actually assist burglars to burgle. Car alarms constantly scream at us in the street and are a source of profoundirritation. A recent survey of the effects of noise revealed (surprisingly?) that dogs barking incessantly in the night rated the highest form of noise pollution on a scale ranging from 1 to 7. The survey revealed a largenumber of sources of noise that we really dislike. Lawn mowers whining on a summer's day, late - night parties in apartment blocks, noisy neighbours, vehicles of all kinds, especially large container trucks thundering through quiet village, planes and helicopters flying overhead, large radios carried round in public places and played at maximum volume. New technology hasalso made its own contribution to noise. A lot of people object to mobile phones, especially when they are used in public places like restaurants or on public transport. Loud conversations on mobile phones invade ourthoughts or interrupt the pleasure of meeting friends for a quiet chat. The noise pollution survey revealed a rather surprising and possibly amusingold - fashioned source of noise. It turned out to be snoring! Wives and husbands in the same bed often have different sleep rhythms, and this is when snoring can be a serious problem. It is not necessary to be near someone who is snoring to be affected. The noise can be just as bad as a noisy truck passing by outside the house.All in all, the problem of noise is a rather difficult one. We seem to be getting used to it, but it is still a nuisance, and, above all, it canbe dangerous. It has been linked to high blood pressure, among other things. Loud noises can really affect people's moods and can cause insomnia and other health problems. It is time we started to take noise pollution seriously.。

Lesson47 Through the earth’s crustSatellites orbiting round the earth have provided scientists with a vast amount of information about conditions in outer space. By comparison, relatively little is known about the internal structure of the earth. It has proved easier to go up than to go down. The deepest hole ever to bebored on land went down 25,340 feet-- considerably less than the height of Mount Everest. Drilling a hole under the sea has proved to be even more difficult. The deepest hole bored under sea has been about 20,000 feet. Until recently, scientists have been unable to devise a drill which would be capable of cutting through hard rock at great depths. This problem has now been solved. Scientists have developed a method which sounds surprisingly simple. A new drill which is being tested at Leona Valley Ranch in Texas is driven by a turbine engine which is propelled by liquid mud pumped into it from the surface. As the diamond tip of the drill revolves, it is lubricated by mud. Scientists have been amazed to find that it can cut through the hardest rock with great ease. The drill has been designed to bore through the earth to a depth of 35,000 feet. It will enable scientists to obtain samples of the mysterious layer which lies immediately below the earth's crust. This layer is known as the Mohorovicic Discontinuity, but is commonly referred to as 'the Moho'.Before it is possible to drill this deep hole, scientists will have to overcome a number of problems. Geological tests will be carried out to find the point at which the earth's crust is thinnest. The three possible sites which are being considered are all at sea: two in the Atlantic Ocean and one in the Pacific. Once they have determinded on a site, they will have to erect a drilling vessel which will not be swept away by ocean currents. The vessel will consist of an immense platform which will rise to 70 feet above the water. It will be supported by six hollow columns which will descend to a depth of 60 feet below the ocean surface where they will be fixed to a huge float. A tall steel tower rising to a height of nearly 200 feet will rest on the platform. The drill will be stored in the towerand will have to be lowered through about 15,000 feet of water before operations can begin. Within the tower, there will be a laboratory, living accommodation and a helicopter landing station. Keeping the platform in position at sea will give rise to further problems. To do this, scientists will have to devise methods using radar and underwater television. If, during the operations the drill has to be withdrawn, it must be possible to re-insert it. Great care will therefore have to be taken to keep the platform steady and make it strong enough to withstand hurricanes. If the project is successful, scientists will not only learn a great deal about the earth, but possibly about the nature of the universe itself.pollution [pә'lu:ʃәn] n.污染overpopulated a.人口多的over-industrialized a.过度工业化的sheer [ʃiә] a.纯粹的，不掺杂的worldwide ['wә:ldwaid] ad.在全世界overwhelm ['әuvә'hwelm] v.制服，使不知所措pollute [pә'lju:t] v.污染pesticide ['pestisaid] n.杀虫剂fertilizer ['fә:tilaizә] n.肥料salmonella [sælmә'nelә] n.沙门氏菌listeria n.利斯特杆菌vegetarian [vedʒә'tєәriәn] n.吃素的人organically-grown a.有机培植的(不施化肥和其他化学药品培植)insidious [in'sidiәs] a.暗中为害的urban ['ә:bәn] a.城市的burglar ['bә:glә] n.窃贼burgle ['bә:gl] v.入室偷窃scream [skri:m] v.尖叫profound [prә'faund] a.极度的irritation ['iri'teiʃәn] n.烦躁incessantly ad.连续不断地whine [wain] v.发呜呜声helicopter ['helikɔptә] n.直升飞机maximum ['mæksimәm] a.最大的technology [tek'nɔlәdʒi] n.技术contribution ['kɔntri'bju:ʃәn] n.贡献mobile ['mәubail] a.可移动的snore [snɔ:] v.打鼾offender [ә'fendә] n.冒犯者staggering ['stægәriŋ] a.令人惊愕的trumpet ['trʌmpit] v.吹号partner ['pa:tnә] n.伙伴污染就是我们为这个人口过密，过度工业化的星球所付出的代价。
(完整版)新概念第三册课文翻译及学习笔记【Lesson46、47、48】
新概念第三册课文翻译及学习笔记【Lesson46、47、48】【课文】So great is our passion for doing things for ourselves, that we are becoming increasingIy less dependent onspecialized labour. No one can plead ignorance of a subject any longer, for there are countless do-it-yourself publications. Armed with the right tools and materials, newlyweds gaily embark on the task of decorating their own homes. Men, particularly, spend hours of their leisure time installing their own fireplaces, laying out their own gardens; building garages and making furniture. Some really keen enthusiasts go so far as to build their own computers. Shops cater for the do-it-yourself craze not only by runningspecial advisory services for novices, but by offering consumers bits and pieces which they can assemble at home. Such things provide an excellent outlet for pent up creative energy, but unfortunately not all of us are born handymen.Some wives tend to believe that their husbands are infinitely resourceful and can fix anything. Even men who can hardly drive a nail in straight are supposed to be born electricians, carpenters, plumbers and mechanics. When lights fuse, furniture gets rickety, pipes get clogged, or vacuum cleaners fail to operate, some women assume that their husbands will somehow put things right. The worst thing about the do-it-yourself game is that sometimes even men live under the delusion that they can do anything, even when they haverepeatedly been proved wrong. It is a question of pride as much as anything else.Last spring my wife suggested that I call in a man to look at our lawn mower. It had broken down the previous summer, and though I promised to repair it, I had never got round to it. I would not hear of the suggestion and said that I would fix it myself. One Saturday afternoon, I hauled the machine into the garden and had a close look at it. As far as I could see, it only needed a minor adjustment： a turn of a screw here, a little tightening up there, a drop of oil andit would be as good as new. Inevitably the repair job was not quite so simple. The mower firmly refused to mow, so I decided to dismantle it. The garden was soon littered with chunks of metal which had once made up a lawn mower. But I was extremely pleased with myself. I had traced the cause of the trouble. One of the links in the chain that drives the wheels had snapped. After buying a new chain I was faced with the insurmountable task of putting the confusing jigsaw puzzle together again. I was not surprised to find that the machine still refused to work after I had reassembled it, for the simple reason that I was left with several curiously shaped bits of metal which did not seem to fit anywhere. I gave up in despair. The weeks passed and the grass grew. When my wife nagged me to do something about it, I told her that either I would have to buy a new mower or let the grass grow. Needless to say our house is now surrounded by a jungle. Buried somewhere in deep grass there is a rusting lawn-mower which I have promised to repair one day.【课文翻译】现在我们自己动手做事的热情很高，结果对于专业工人的依赖越来越少了。

(英音版)新概念英语第三册第47课：Too high a price
（英音版）新概念英语第三册第47课：Too high apriceLesson 47：Too high a price? 代价太高？Listen to the tape then answer the question below.听录音，然后回答以下问题。
What does the writer describe as an 'amusing old-fashioned source of noise'?Pollution is the price we pay for an overpopulated, over industrialized planet. When you come to think about it, there are only four ways you can deal with rubbish： dump it, burn it, turn it into something you can use again, attempt to produce less of it. We keep trying all four methods, but he sheer volume of rubbish we produce worldwide threatens to overwhelm us.Rubbish, however, is only part of the problem ofpolluting our planet. The need to produce ever-increasing quantities of cheap food leads to a different kind of pollution. Industrialized farming methods produce cheap meat products： beef, pork and chicken. The use of pesticides and fertilizers produces cheap grain and vegetables. The price we pay for cheap food may be already too high： Mad Cow Disease (BSE) in cattle, salmonella in chicken and eggs, and wisteria in dairy products. And if you think you'll abandon meat and become a vegetarian, you have the choice of very expensive organically-grown vegetables or a steady diet of pesticidesevery time you think you're eating fresh salads and vegetables, or just having an innocent glass of water!However, there is an even more insidious kind ofpollution that particularly affects urban areas and invadesour daily lives, and that is noise. Burglar alarms going offat any time of the day or night serve only to annoy passers-by and actually assist burglars to burgle. Car alarms constantly scream at us in the street and are a source of profound irritation. A recent survey of the effects of noise revealed (surprisingly?) that dogs barking incessantly in the night rated the highest form of noise pollution on a scale ranging from 1 to 7. The survey revealed a large number of sources of noise that we really dislike. Lawn mowers whining on a summer's day, late-night parties in apartment blocks, noisy neighbors, vehicles of al kinds, especially large container trucks thundering through quiet village, planes and helicopters flying overhead, large radios carried round in public places and played at maximum volume. New technologyhas also made its own contribution to noise. A lot of people object to mobile phones, especially when they are used in public places like restaurants or on public transport. Loud conversations on mobile phones invade our thoughts orinterrupt the pleasure of meeting friends for a quiet chat. The noise pollution survey revealed a rather spurring and possibly amusing old fashioned source of noise. It turned out to be snoring! Men were found to be the worst offenders. It was revealed that 20% of men in their mid-thirties snore.This figure rises to a staggering 60% of men in their sixties. Against these figures, it was found that only 5% of women snore regularly, while the rest are constantly woken or keptawake by their trumpeting partners. Whatever the source of noise, one thing is certain： silence, it seems, has become a golden memory.New words and expressions 生词和短语pollutionn. 污染overpopulatedadj. 人口多的over-industrializedadj. 过度工业化的sheeradj. 纯粹的，不掺杂的worldwideadv. 在全世界overwhelmv. 制服，使不知所措pollutev. 污染pesticiden. 杀虫剂fertilizern. 肥料。

但是，还有一种更加隐蔽有害的污染，它专门影响城镇地区，侵袭我们的日常生活，那就是噪音。防盗警报器在白天和黑夜的任何时候都会响起来，它的作用只是骚扰过路行人，而实际上却帮助窃贼入室行窃。在街上，汽车的防盗警报不断对我们吼叫，这是人们极度烦燥的一个原因，最近一个有关噪音的作用的调查（令人吃惊地）指出，夜间连续不断的狗叫声，在一个从1级至7级刻度表上应列为最严重的噪间污染。这个调查揭示了我们所不喜欢的大量的噪间的来源：夏天呜呜作响的割草机，公寓楼里深夜聚会的喧哗声，大声吵闹的邻居，各式各样的车辆，特别是穿越寂静的村庄的集装箱卡车，从头顶飞过的飞机和直升机，被带到公共场所、音量开到最大的大功率收音机。新技术也为噪音作了它的贡献。许多人都反对移动式电话，特别是在如饭店，公共交通车等公共场所使用移动电话。用移动电话大声交谈干扰我们的思路，破坏我们和朋友在一起轻声聊天所得到的乐趣。这个有关噪音的污染调查还揭示了一种出人意外而同时可能会引人意外而同时可能会引人发笑的老式噪音源。它竟然是鼾声。人类是这方面的罪魁祸首。调查指出，20%的35岁左右的男人打鼾；而到60岁这个年龄段，这个数字上升到令人惊愕的60%。与这些数字相比，只有5% 的女性经常打鼾；而其余则经常被与她们同睡、像吹号似地打着呼噜的男人吵醒或弄得睡不着。不管噪声来自何方，有一点是肯定的：看来寂静已变成一种珍贵的回忆。
然而，垃圾只是我们这个星球的污染问题的一个方面。日益增长的对廉价食物的需求导致了另一种形式的污染。工业化的农作方式生产出廉价的肉类制品——牛肉、猪肉和鸡肉。使用杀虫剂和化肥生产出廉价的谷物和蔬菜。为了廉价食物我们付出代价已经太高了：牛肉中的疯牛病，鸡肉和鸡蛋中的沙门氏菌，奶制品中的利斯特杆菌。如果你想放弃肉类而变成一位素食者，那么你可以两者择一：或是选用价格昂贵、有机培植的蔬菜，或是当你认为在享用新鲜色拉和新鲜蔬菜或饮用一杯无害的水的时候，实际上每次都不断吃进杀虫剂。
