Part 1 Dictation
　　The Polluted Environment
　　Our environment is being polluted faster than nature and man's present efforts can prevent it. / Time is bringing us more people, / and more people will bring us more industry, / more motor vehicles, larger cities, and the growing use of man-made materials. / What can explain and solve this problem? / The fact is that pollution is caused by man / --by his desire for a modem way of life. / We make increasing industrialization our chief aim. / For its sake, we are willing to sacrifice everything: / clean air, pure water, good food, our health and the future of our children. / There is a constant flow of people from the countryside into the cities, / eager for the benefits of modem society. / But as our technological achievements have grown in the last twenty years, / so pollution has become a serious problem. / Isn't it time we stopped to ask ourselves where we are going and why? /
　　[注意]vehicles(交通工具)的拼写；industrialization工业化；sacrifice牺牲；technological技术的；最后一句用了虚拟语气，注意stop要用过去时。
