分析 污染
在幾百年前，生活比現在更困難．人們沒有現代的機器，也沒有現代化的機器．現在的生活有新的問題了．其中最大的問題之一是污染．水污染使我們的河流，湖里殺死了很多魚，也污染了我們的飲用水．噪音是我們的說話聲音大并且變得也更容易生氣．空氣污染是最嚴重的一種污染．在世界上對所有的生物都有害的．
所有的汽車，飛機和工廠每天都污染我們的空氣．有時候空氣污染很厚以至于像一個最惡的城市，這種被子就叫做霧吸．
許多國家正在制作制度與污染作斗爭．在污水被扔之前工廠必須使污染水干凈．他們一定不能使臟的濃煙吹到空氣中．
我們需要做許多別的事情．我們巴特把垃圾在垃圾箱里，而不是把它扔在地上．我們可以乘坐公共汽車去上班或者乘坐同一輛車．如果很少有人開車，就將會有更少的污染．制度是不夠的，每個人必須幫助減少污染．
