　　公共英语考试一级阅读：NaturalResources
　　Through the changes in the ways of making a living in a family over several generations, the cartoon aims at sounding a warning against man’s wasteful use of natural resources and emphasizing the urgent need to preserve these resources.
　　Ever since man appeared on the earth, man’s survival has been heavily dependent on nature. Almost everything we use in our everyday life comes from nature, ranging from the food we eat, the water we drink, to the wood which is turned into furniture. With the development of technology and population growth, the amount and range of materials used has increased at an alarming rate.
　　 However, natural resources are not inexhaustible. Some reserves are already on the brink of exhaustion and there is no hope of replacing them. The widespread water shortage is an example in point. If man continued to squander natural resources with no thought for the future, the whole world would be in a mess.
　　 Useful Words and Expressions:
　　 1. make a living 谋生
　　 2. aim at 瞄准
　　 3. aim high 胸怀大志
　　 4. alarming使人惊动的
　　 5. inexhaustible 无穷无尽的
　　 6. squander 浪费
　　 7. be in a mess 乱七八糟
