Car Pollution(汽車污染)
Car PollutionEach year there is an increasing number of cars on the roads as millions of new cars are produced. One out of six Americans works at making cars, driving trucks, building roads or filling up gas. Americans couldn't live without cars!
Most Americans would find it hard to imagine life without a car. However, some have realized the serious problem of air pollution caused by cars. The polluted air becomes poisonous and dangerous to health.
One way to get rid of the polluted air is to make a car without pollution. But to build a clean car is easier said than done. Progress in this field is slow.
Another way is to replace car engines with something else. Inventors are now working on steam cars as well as electric cars. Many makers believe that it will take years to develop a practical model for us.
To prevent the world from being polluted by cars, we have to make some changes in our lives. Americans, for example, have to cut down on the number of their total cars.They are encouraged to use bicycles, which are thought to help keep the air clean.
But this change does not come easily. A large number of workers may find themselves without jobs if a car factory cioses down. Thus the problem of air pollution would become less important than that of unemployment. Although cars have led us to a better life, they have also brought us new problems.
汽車污染
上路的汽車數量逐年增長，同時，每年都會生產出幾百萬輛新車。在美國，每六個人中就有一個從事與汽車相關的工作：造車、開車、修路、加油等等。 離開汽車，美國人無法生活!
大部分美國人簡直無法想象沒有車的生活會是什么樣子。但是一些人也已經意識到汽車造成的空氣污染已成為嚴重的問題。被污染的空氣具有毒性，并且危害健康。
解決空氣污染的方法之一就是制造無污染汽車。但是生產清潔汽車說來容易做來難。 目前，這一領域的進展十分緩慢。
另一個方法就是使用其他東西替代汽車發動機。發明家正在研制蒸汽汽車和電車。但是許多廠家認為我們可以使用的實用型汽車的誕生可能還需要幾年時間。
要想阻止全球化的汽車污染，我們需要對自己的生活方式做出適當的改變。例如，在美國，需要縮減汽車總量。鼓勵人們使用有助空氣清潔的自行車。
但這種改變不能一蹴而就。一旦汽車工廠關閉，就會有大量工人失去工作。與失業相比，空氣污染似乎就不再那么重要了。盡管汽車為我們帶來了更加舒適的生活，同時，它也帶來了新的問題。
