阅读理解 In many countries today, laws protect wildlife．In India, the need for such protection was realized centuries ago． About 300 B．C．an Indian writer described forests that were somewhat like national parks today．The killing of beasts was carefully supervised(监视)．Some animals were fully protected．Within the forest, nobody was allowed to cut wood for building, burn wood for charcoal(木炭), or catch animals for their furs．Animals that became dangerous to human visitors were caught or killed outside the park so that other animals would not become uneasy． The need for wildlife protection is greater now than ever before．About a thousand species of animals are in danger of extinction, and the rate(速度)at which they are being destroyed has increased．With mammals(哺乳动物), for example, the rate of extinction was about one species every fifty years from A．D．1 to 1 800, but now it is about one species every year．Everywhere, men are trying to solve the problem of protecting wildlife caring for the rapid growth of the world’s population． |
