考题 Motor vehicles powered by the internal combustion engines are responsible for over 80 percent of the deadly carbon monoxide as well as the cancer-causing substances in the air. Eighty-nine percent of the vehicles on the road in Massachusetts are privately owned and are often operated with only one person in the car. If people would use public transportation instead of their cars, air pollution levels could be significantly lowered. Thirty percent of the land in downtown Boston is devoted to cars. Where there are garages, there could be gardens. Where there are highways, there should be homes and places to work and play. Studies show that people today show a greater hearing loss with age than ever before. Much of this is due to car-horns, loud engines and general traffic noise.The cost of a personal car is high to the individual. The average person pays about $2,000 per car per year in gasoline, insurance, taxes, and maintenance. But for society as a whole, personal cars are a luxury we cannot afford.

Man has also modified the face of the earth by draining marshes and cutting through mountains tobuild roads and railways.However,man's changes to the physical environment have not always had beneficial results.Today, pollution of the air and water is an increasing danger to the health of the planet.Each day thousands of tons of gases come out of the exhausts of motor vehicles;smoke from factories pollutes the air of industrialized areas and the surrounding areas of countryside.The air in cities is becoming increasingly unhealthy.The pollution of water is equally harmful.In the sea,pollution from oil is increasing and is killing enor- mous numbers of algae（水藻）,fish and birds.The whole ecological balance of the sea is being changed.
