Pollution: a Social Problem
   When we read newspapers, we often come across the word pollution. This word was not familiar to the people some decades ago. But now, it is a serious threat to us because.it means the poisoning of the air, seas, rivers and lands, which would do harm to our health.
   There are many factories that bring pollution to us. We can not have fresh air in the morning. This is mainly because of the poisonous smoke coming from factories, especially chemical ones. In rivers, seas and oceans, there are industrial wastes. Some factories just throw their wastes into seas or let them flow into rivers. When people drink the water from such rivers, they get poisoned. Besides, there is rubbish from ships and when sometimes an accident occurs in an ocean, oil flows out from tankers 1.
   On land, the accumulation of rubbish in the streets may dirty the city and ruin our health. This is mainly due to the improper 2 disposal 3 of rubbish by people.
   If we do mot fight against pollution, surely one day all of us will be killed. Some people like to put the blame on the industrial revolutions. On the contrary, the pollution problem will be solved only with the help of modem 4 science and technology.
污染——一个社会问题
   我们看报的时候,经常会看到“污染”这个词。这个词对于几十年前的人来说并不熟悉。然而对于我们来说,它是一个严重的威胁,因为它意味着危害空气、海洋、河流和土地,进而对我们造成伤害。
   有很多工厂给我们带来了污染。早上我们呼吸不到新鲜的空气。这主要是因为这些工厂里排放出有毒的气体,尤其是化工厂。在江河湖海里到处都有工业垃圾。一些工厂把废弃物排放到江河和海洋里。人们喝了这里面的水就会中毒。除此之外,还有从船上扔下来的垃圾和海洋里发生事故的船只流出来的油。
   在陆地上,街道上乱扔的垃圾不仅影响市容,还危害我们的健康。这主要是因为人们对垃圾的不正确的处理。
   我们如果不对污染采取措施,总有一天我们会被杀死的。有些人总爱把这归咎于工业革命。相反,污染问题还必须靠现代科学和技术来解决。
