分析 污染
在几百年前，生活比现在更困难．人们没有现代的机器，也没有现代化的机器．现在的生活有新的问题了．其中最大的问题之一是污染．水污染使我们的河流，湖里杀死了很多鱼，也污染了我们的饮用水．噪音是我们的说话声音大并且变得也更容易生气．空气污染是最严重的一种污染．在世界上对所有的生物都有害的．
所有的汽车，飞机和工厂每天都污染我们的空气．有时候空气污染很厚以至于像一个最恶的城市，这种被子就叫做雾吸．
许多国家正在制作制度与污染作斗争．在污水被扔之前工厂必须使污染水干净．他们一定不能使脏的浓烟吹到空气中．
我们需要做许多别的事情．我们巴特把垃圾在垃圾箱里，而不是把它扔在地上．我们可以乘坐公共汽车去上班或者乘坐同一辆车．如果很少有人开车，就将会有更少的污染．制度是不够的，每个人必须帮助减少污染．
