Recycling is nothing new .Waste paper,rings,and many other things have been recycled in many different ways for many years. It is only the word that is new.But now that natural materials are difficult to find,many countries are experimennting with other ways of keeping materials.
In the USA,a publishing firm has brought out several books on the pollution and waste in the United States.The books are made of recycled paper--paper that has been used before.In the way,several thousand trees are saved.One clever schoolboy has worked it out that if evert schoolbook in the USA is recycled,there would be enough paper for fifty packets of peanuts for every child in the world for five years.He does not say where the peanuts come from.
Several films are experimenting with making containers from hard plastic which,when the containers are finished,can be uesd as building materials.If mountains of empty cans all over the world can be changed into building materials,it will be a new source of material.

參考答案:（原料的）再循环使用不再是什么新鲜事物。在很多年的时间里，废纸、环状物和其他的东西已经被循环使用了。只是再循环使用这个称呼比较新而已。但是既然自然资源很难找到，很多国家正在测试用其方式他保持材料。
在美国，一家美国的出版公司已经用污染物和废弃物生产出一些书籍。这些书是由再循环使用的纸张制造而成的——这些纸张已经被使用过。用这样的方式，几千棵树可以被挽救。一个聪明的男学生计算出，在美国，如果每本教科书都被循环使用，将会有足够的纸张可以在五年的时间里，为全世界每个儿童每年提供50个装花生用的（纸质）包装袋。他没有说明这些花生从何而来。
几家工厂正在试验用硬塑料做容器，这些容器被使用完毕后可以被用作建筑材料。如果全世界堆积成山的易拉罐可以被转化成建筑材料的话，它将是一个新的材料来源。
