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 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 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 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.

参考译文
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。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。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。
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。
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。

课文详注 Further notes on the text
1．A public house which was recently bought by Mr. Ian Thompson is up for sale. 伊恩·汤普森先生最近才买的一个小酒店现在又要卖出去。
（1）在英国英语中，public house指酒馆、酒店，口语中往往缩略为pub：
I had lunch at a village pub.
我在一家乡村小酒店吃了午饭。
（2）up for sale表示“供新概念”，up为形容词，含义为“已提出的”、“供……的”。
2．He told me that he could not go to sleep one night because he heard a strange noise coming from the bar. 他告诉我有天夜里他怎么也睡不着，因为他听到酒吧里传来一阵奇怪的响声。
（1）从that一直到句尾都是told的直接宾语，其中because引导的原因状语从句说明为什么睡不着的原因。
（2）coming为现在分词，它引导的短语修饰noise，为宾语补足语。它也可以变为从句结构：a strange noise that came from the bar。在一些表示感觉的动词如see，hear，feel，watch，notice 等之后，往往用宾语+宾语补足语这个结构，其宾语补足语既可以是不定式（通常不加to），也可以是现在分词，两者在意义上区别不大，现在分词表示动作正在发生，不定式则表示动作发生了：
I heard someone knocking at the door.
我听到有人正敲门。
I heard you sing this song yesterday.
昨天我听到你唱这支歌。
（3）bar为酒吧或酒店中卖酒的柜台。
3．…they were on in the morning.……早晨灯都亮着。
on为形容词，表示“开着的”、“接通的”，其反义词为off：
When he arrived home, he found that all the lights were on/ off.
他到家时发现所有的灯都亮着／关着。
Is the TV on? I thought I had turned it off.
电视机是开着的吗？我以为我把它关掉了。
4．He also said that he had found five empty whisky bottles which the ghost must have drunk the night before. 他还说他发现了5只空的威士忌酒瓶子，这肯定是鬼魂头天晚上喝的。
（1）由于是对已发生的事表示推测，因此must后面要用完成时。
（2）that引导的为间接引语，因此时间状语要变动。直接引语中的时间状语为 last night，转述时变成了 the night before。其他时间状语的变化有：now→then，two days ago→two days before/ earlier，today→that day，tonight→that night，tomorrow→the next/ following day，last night→the night before等。
5．…they will not accept the pub even if he gives it away.……即使他把小酒店白送人，他们也不要。
（1）连词 even if表示“即使”，它引导的让步状语从句含有很强的假定性：
I won't have dinner with him even if he pays for it.
即使是他付钱我也不和他一起吃饭。
（2）give away是个固定短语，其含义之一是“赠送”、“免费给予”：
He gave all his books away to the library.
他把他所有的书都赠给了图书馆。
