Why was the village silent?

In this much-travelled world, there are still thousands of places which are inaccessible1 to tourists. We always assume that villagers in remote places are friendly and hospitable2. But people who are cut off not only from foreign tourists, but even from their own countrymen can be hostile to travellers. Visits to really (1)_______ villages are seldom enjoyable -- as my wife and I discovered during a tour through the Balkans.

We had spent several days in a small town and visited a number of old churches in the vicinity. These attracted many visitors, for they were not only of great architectural interest, but contained a large number of beautifully preserved frescoes4 as well. On the day before our (2)______, several bus loads of tourists descended5 on the town. This was more than we could bear, so wedecided6 to spend our last day exploring the countryside. Taking a path which led out of the town, we crossed a few fields until we came to a dense7 wood. We expected the path to endabruptly8, but we found that it traced its way through the trees. We tramped through the wood for over two hours until we arrived at a deep stream. We could see that the path continued on the other side, but we had no idea how we could get across the stream. Suddenly my wife spotted9a boat moored11 to the bank. In it there was a boatman fast asleep. We gently woke him up and asked him to ferry us to the other side. Though he was (3)________ to do so at first, we eventually persuaded him to take us.

The path led to a tiny village perched on the steep sides of a mountain. The place (4)______ of a straggling unmade road which was lined on either side by small houses. Even under a clear blue sky, the village looked forbidding, as all the houses were built of grey mud bricks. The village seemeddeserted12, the only sign of life being an ugly-looking black goat on a short length of rope tied to a tree in a field nearby. Sitting down on a dilapidated wooden fence near the field, we opened a couple of tins of sardines14 and had a picnic lunch. All at once, I noticed that my wife seemed to be filled with alarm. Looking up I saw that we were surrounded by children in rags who were looking at us silently as we ate. We offered them food and spoke15 to them kindly16, but they remained motionless. I concluded that they were simply shy of strangers. When we later walked down the main street of the villager, we were followed by a silent procession of children. The village which had seemed deserted, immediately came to life. (5)_____ appeared at windows. Men in shirt sleeves stood outside their houses and glared at us. Old women in black shawls peered at us from doorways17. The most frightening thing of all was that not a sound could be heard. There was no doubt that we were unwelcome visitors. We needed no further warning. Turning back down the main street, we (6)______ our pace and made our way rapidly towards the stream where we hoped the boatman was waiting.

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。
