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 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 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 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 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 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 has 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 or interrupt 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 kept awake by their trumpeting partners. Whatever the source of noise, one thing is certain: silence, it seems, has become a golden memory.　　新概念英语3逐句精讲：　　　1.Pollution is the price we pay for an overpopulated, over industrialized planet.　　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。　　语言点:the price we pay for的意思是&我们为…而付出的代价&。　　2.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.　　当我们开始考虑垃圾问题时，我们只有4种对付垃圾的方法：倾倒、焚烧、把垃圾变成再生材料或试图少产生一些垃圾。　　3.We keep trying all four methods, but the sheer volume of rubbish we produce worldwide threatens to overwhelm us.　　我们一直在试这4种方式，但是，我们在世界范围内仅产生的垃圾的量就有把我们覆盖的危险。　　语言点:keep doing与try to do的含义不同，意为&一直在做某事（几乎从未间断过）&。　　4.Rubbish, however, is only part of the problem of polluting our planet.　　然而，垃圾只是我们这个星球的污染问题的一个方面。　　语言点:近几年由于人类的行为而导致的严重疾病:　　Mad cow disease 疯牛病；bird flu 禽流感；A（H1N1）甲型H1N1流感；SARS（Severe Acute Respiratory Syndrome）非典型肺炎　　5.The need to produce ever-increasing quantities of cheap food leads to a different kind of pollution.　　日益增长的对廉价食物的需求导致了另一种形式的污染。　　语言点:lead to的意思是&导致&。
