The earth’s valuable rain forests are in danger. They are getting smaller and the situation is becoming worse. This problem influences the whole world.

Rain forests are the natural habitat for many rare and beautiful animals, birds and insects. There’re various plants as well. For example, the Amazon rain forest in Brazil has a richer plant life than anywhere else on the earth. Some of the plants there are important for medical science. Aspirin, a drug which reduces fever and kills pain, is made from tree bark. Cough medicine can be produced from tree resin. Perhaps they may help us cure disease such as cancer and AIDS one day.

It is a great pity that the rain forests are disappearing. There are two reasons. In many countries the trees have been cut down because the land is needed for animals and crops. In other parts of the world the trees are cut down because their wood is wanted. This wood is used by local people for firewood, or is sold to Japan, Europe and North America. It is used for buildings or made into furniture there.

The soil in the forests is indeed very thin. Without trees and plants, it is easily washed away by the rain or blown away by the wind. Soon nothing can be grown on it and the rain forests then become useless. In addition, the forests cannot produce O2 or absorb CO2. This leads to the greenhouse effect(温室效应), which makes the earth hotter and hotter.

When the forest is destroyed, it is not only the trees that are lost, the homes of millions of animals are destroyed too. Also kinds of animals are in danger—fish, reptile, birds, mammals, insects and shellfish—as well as thousands of plants. If we do not act immediately to save our rain forests, some of them will be gone.

In early November of 1503, during Christopher Columbus’ fourth and final trip to America, his ship was seriously damaged in a storm. Columbus and his men had to live on a small island for several months while they tried to repair their ship and return to Spain.

At first, the local people on the island were very kind to the European visitors, giving them all the food and clothes they needed to survive. However, as the months passed, the local people became more and more unhappy with their guests, who were tricking and stealing from them. Finally the locals decided to stop helping. Without food or any way to leave the island, Columbus’ group was soon in serious trouble.

Luckily for Columbus, he had a book about the stars and planets on his ship. It described the movements of all the objects in the night sky. The book, written by a well-known German scientist, said there would be a total lunar eclipse (月食) on the evening of February 29, 1504 and how long it would last.

Columbus worked out the difference in time between Germany and North America. He then had a meeting with the local leaders just before the eclipse would take place. In this meeting, Columbus told them his god was angry because the local people were no longer giving food. So his god would take away the moon to punish them. At the moment Columbus finished talking, just as he had planned, the moon began disappearing.

The local leaders grew frightened and quickly agreed to provide Columbus with food and anything else he wanted. But first, Columbus’ god had to return the moon. Columbus told them he would have to discuss the idea with his god on his ship. Knowing the moon would stay completely hidden for about 48 minutes, Columbus returned just before the moon began to reappear. From that day on, until they finally

left, Columbus and his men no longer had any trouble getting the food they needed.
