　　Poeple 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!
生活在乡村的人比城镇的人更健康。这是因为在乡村的空气很新鲜。农民们整天在田野工作，呼吸新鲜洁净的空气。但在城市有太多的工厂。他们生产出更多的有害气体。最后，城市里满是烟。城市里也有很多灰尘。这可能导致疾病。所以，新鲜的空气对城市里的人很重要。我们需要新鲜空气。所以请不要污染空气！
