each year there is an increasing number of cars on roads and streets 最好 是自己翻译的
Each year there is an increasing number of cars on roads and streets as millions of new cars are produced. One out of every six Americans works at putting together the parts of cars, driving trucks, building roads or filling cars with gas(汽油). American won't live without cars!
Most Americans find it hard to think what life would be like without a car. However, some have realized the serious problem of air pollution by cars. The polluted air is poisonous(有毒的) and dangerous to health.
One way to get rid of(排除) the polluted air is to build a new kind of car. That's what several of the large car factories are trying to do. But to build a clean car is easier said than done. Progress in this field has been slow.
Another way is to take the place of the car engine(发动机) by something else. Engineers are now working on some new cars. Many makers believe that it will take years to develop a practical model that pleases man.
To prevent the world from being polluted by cars, we'll have to make some changes in the way many of us live. Americans, for example, have to cut down on the number of their cars. They are encouraged to travel and go to work by bike. Riding a bike is 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 closes down. And the problem of air pollution would become less important than that of unemployment(失业).
Although cars have brought us a better life, they have also brought us new problems.优质解答
每年有越来越多的在道路和街道上作为百万辆新车被生产出来.每天有六名美国人被放在一起工作部分汽车、开车、修路、充填汽车燃气(汽油).美国人没有车不能活!
大多数美国人很难认为,生活没有车会是什么样子.然而,一些人已经认识到了严重的空气污染问题由车产生.污染物是有毒的,并且危害健康.
一个办法摆脱(排除)污染的空气是建立一种新的汽车.那是几个大型的汽车工厂正在试图做的.但是生产清洁汽车是说起来容易做起来难.目前,这一领域的进展缓慢.
另一种方法是由其他东西代替汽车发动机.工程师正在研究一些新车.许多制造商认为,这将花费数年的时间来发展一套可以实际应用模型,使人感到喜悦.
为了防止世界被汽车污染,我们得做许多改变在我们生活中.例如,美国人,不得不削减他们的汽车的数量.他们被鼓励去旅行,骑自行车去上班.骑脚踏车是认为可以帮助保持空气清新.
但这种改变并不容易——有一大批工人可能会发现自己没有工作一旦汽车工厂关闭.失业问题将会变得比环境污染问题更重要.
虽然汽车给我们带来了一个更好的生活,但它们也带给我们新的问题
