Now, we may have an unlikely helper to help clean up our garbagea small wax worm.The worms hidden skills were discovered by accident.About
11、 two years ago, Federica Bertocchini, a developmental biologist at the Spanish National Research Council and an amateur beekeeper, was cleaning out bees nest that had been filled with worms. She removed the worms and put them in a plastic bag while doing the cleaning.After finishing, she went back t
12、o the room where she had left the worms, and found they had escaped from the bag.When she checked, she saw that the bag was full of holes.Realizing she may have made an important discovery，Bertocchini teamed up with other researchers to conduct further research.They began by placing 100 worms on som
13、e plastic bags and discovered that over a 24hour period, the worms managed to chew through 92 milligrams of plastic.The researchers make an appropriate judgment that at this rate, the group of worms could degrade (降解) an averagesized 5.5gram plastic bag within a month.To rule out the possibility tha
14、t chewing was causing the degradation, the researchers spread the soft wet substance inside the body of some recently dead worms on a sheet of plastic.Sure enough, even the liquid was able to eat through the material，confirming that the worms have plasticdigesting enzymes (酶)While the news is certai

17、d, the researcher wants to identify the enzyme that helps degrade the plastic. The researcher says，maybe we can find the molecule (分子) and produce it on an industrial level, rather than using a million worms in a plastic bag.语篇解读西班牙生物学家Federica Bertocchini爱好养蜜蜂，她在清理蜂巢时意外发现了一种能吃塑料的蜡虫，她和她的团队对此进行了研究，她的
18、这一发现未来有望用于治理白色污染。5What did the experiment of using dead worms find out?AWorms chewing may cause the degradation.BA plasticeating chemical exists in wax worms.CDead worms are effective in dealing with plastic.DIt takes a long time for worms to degrade plastic.解析：细节理解题。根据第三段中的“To rule out the possibil
19、ity that chewing.the worms have plasticdigesting enzymes.”可知，研究者们将刚刚死去的虫子体内的浆液置于一片塑料上，结果发现这种液体也有降解塑料的作用，并得出蜡虫体内含有一种可降解塑料的酶这一结论。故选B。答案：B6What is Ramani Narayans attitude to Bertocchinis finding?AObjective.BConvinced.CQuestioning. DOptimistic.解析：观点态度题。根据倒数第二段中的“While the news is certainly encouraging,

21、他们的发现很令人振奋，但并不是每个人都信服，Ramani Narayan就是其中一个。他认为，生物降解(此处指通过蜡虫来降解塑料)可能会携带有害物质，并将其输送到食物链中，甚至会给环境和人类健康带来更多的危害。由此可推知，Ramani Narayan对Bertocchini的发现持“怀疑的”态度。故选C。答案：C7What might Bertocchini focus her later research on?AThe structure of plasticdegrading enzymes.BThe use of other worms in disposing plastic.CWa
