People in villages are healthier than people in towns. That is because the air in villages is very fresh. Farmers are working all day in the fields, breathing fresh clean air. But there are too many factories in cities. They produce more and more harmful gases. At last, cities are full of smoke. And there's many dust in cities,too. It may cause a disease. So fresh air is very important to the people in cities. We need fresh air. So please don't pollute the air!
人在农村比城镇更健康的人。那是因为乡村的空气很清新。农民整天在田里工作，呼吸新鲜空气清新。但城市里有太多的工厂。他们生产越来越多的有害气体。最后，城市充满了烟雾。城市里也有很多灰尘。它可能会导致一种疾病。因此，新鲜的空气对城市的人是非常重要的。我们需要新鲜的空气。所以请不要污染空气！
