Question

      All animals produce waste. We call it awaste/' but we all know it can be very useful. In some parts of the world,animal waste,or poop,is collected,dried,and burned for cooking and heating. 36

      The Chengdu Giant Panda Breeding Center has an unusual way of using animal “waste." The center's 40 pandas produce about two tons of poop a day. This material is being turned into a new product called Panda Poop Paper. 37 After all,paper is made from plant fiber,which cannot be digested and simply goes through the body as waste.

     Since pandas eat nothing but bamboo,their “waste” is perfect paper material. 38 Their stomachs haven’t fully developed for their vegetarian diet,so their bodies make use of just 20% of what they eat. The other 80% comes out as poop: very high in fiber and perfect for paper. Once the poop is collected,it is cleaned with chemicals,crushed（碾碎） and put into frames (框架) to dry. 39. Because of its good quality as well as the worldwide popularity of the panda,gift products made from the paper sell well.

    40 They got the idea from the elephant dung(大象粪) paper made at the Elephant Conservation Center in Chiang Mai,Thailand. And Creative Paper Wales in the U.K. sells paper gifts made from sheep waste.

   A. It's not so strange!

   B. Where does the paper come from?

   C. What,s more,pandas have a special advantage.

   D. After these steps,it becomes very good,strong paper.

   E. But have you ever heard of paper that's made from poop?

   F. Farmers have been using animal and human waste for a long time.

   G. Surprisingly,the Chinese weren't the first to make paper from aftimal         waste.

Answer 1

37. A 38. C 39. D

36. E。根据文章接下来介绍熊猫的粪便被制作成为纸张可知，尽管大家听 说过动物粪便的诸多用处，但是你听 过由粪便制成的纸张吗？

37. A.根据下一句中的After a1.paper is made from plant fiber 可知，由于纸 张本来就是由纤维组成的，因此用纤 维含量高的熊猫粪便制作纸张也就不足为奇。

38. C.接下来介绍的“熊猫只能吸收其 所吃的20%,剩余80%富含纤维的食 物都随粪便排出体外”是熊猫的一个特殊优势。

39. D.根据上一句中的collectSil ,cleaned,crushed和 dry 可知，经过这 些程序后，熊猫的粪便被制作成为非 常好用且结实的纸张。 

40. G；根据下一句 They got the idea from the elephant-dung paper made at the Elephant Conservation Center in Chiang Mai,Thailand 可知，咱们中齒 不是第一个想到用动物粪便制作纸 张的国家。
