C
There are energy savings to be made from all recyclable materials, sometimes huge savings. Recycling plastics and aluminum, for instance, uses only 5% to 10% as much energy as producing new plastic or smelting(提炼)aluminum.
Long before most of us even noticed what we now call "the environment," Buckminster Fuller said, "Pollution is nothing but the resources(资源)we are not harvesting. We allow them to be left around because we've been ignorant of their value." To take one example, let's compare the throwaway economy(经济)with a recycling economy as we feed a cat for life.
Say your cat weigh 5kg and eats one can of food each day. Each empty can of its food weights 40g. In a throwaway economy, you would throw away 5,475 cans over the cat's 15-year lifetime. That's 219kg of steel-more than a fifth of a ton and more than 40 times the cat's weight.
In a recycling economy, we would make one set of 100 cans to start with, then replace them over and over again with recycled cans. Since almost 3% of the metal is lost during reprocessing, we'd have to make an extra 10 cans each year. But in all, only 150 cans will be used up over the cat's lifetime-and we'll still have 100 left over for the next cat.
Instead of using up 219kg of steel, we've used only 6kg. And because the process of recycling steel is less polluting than making new steel, we've also achieved the following significant savings: in energy use-47% to 74%; in air pollution-85%; in water pollution-35%; in water use-40%.
28. What does Buckminster Fuller say about pollution?
A. It is becoming more serious.
B. It destroys the environment.
C. It benefits the economy.
D. It is the resources yet to be used.
29. How many cans will be used up in a cat's 15-year lifetime in a recycling economy?
A. 50 B. 100 C. 150 D. 250
30. What is the author's purpose in writing the text?
A. To promote the idea of recycling.
B. To introduce an environmentalist.
C. To discuss the causes of pollution.
D. To defend the throwaway economy.
答案解析：
28. D 根据第二段，Buckminster Fuller说：“污染只不过是我们尚未利用的资源。我们让它们散落在周围，因为我们忽视了它们的价值。”这表明他认为污染实际上是未被使用的资源。
29. C 根据第四段，作者计算了在回收经济中，猫的15年寿命期间总共会使用150个罐头。文中提到，除了最初的100个罐头，每年还需要额外制造10个罐头来替换损耗，15年就是150个罐头。
30. A 文章通过比较丢弃经济和回收经济中猫粮罐头的使用情况，展示了回收可以节省大量资源并减少污染。作者的目的显然是推广回收利用的理念，鼓励读者采取回收行动。
