Question

(2014 •抚州中考) 

   The earth is 4 ,600 million years old. We humans have lived on the earth for only 35 ,000 years,but during this period we have changed our planet a lot in many ways. Some things we’ve done are very good for the earth while some are bad.

   Fewer trees All over the world,people have cut down millions of trees. When it rains or when the wind blows,the earth is taken away. Forests have become deserts. So more and more sorts of animals and plants are disappearing.

   Traffic and factory pollution In big cities,cars and buses have polluted the air. Now many people in cities have health problems. Factories have also polluted the land and the water. As a result,many rivers and lakes are now dead.

   The ozone layer (臭氧层) Around the earth there's a special kind of oxygen (0₂) called “ozone”(0₃) . It's important to the earth. But now air pollution is destroying it and that has made a very big hole in the ozone layer. Too much harmful radiation (福射) from the sun passes through the hole and reaches the earth directly. This is very dangerous because this kind of radiation can cause cancer.

   More carbon dioxide (C0₂) Carbon dioxide in the air has increased a lot. It mainly comes from burning oil,coal and wood. This has formed a “blanket” around the earth. The heat from the sun can't escape so the temperature is rising. This is called “ the greenhouse effect (温室效应) ”.It causes the level of the oceans to rise and the climate (气候) of the earth to change.

   All these problems are very serious,so we must do something now.
