2、of some hungry worms.,greater wax moth,Researchers in Spain and England recently found that the worms of the greater wax moth can break down polyethylene，which accounts for 40% of plastics. The team left 100 wax worms on a commercial polyethylene shopping bag for 12 hours，and the worms consumed and

3、broke down about 92 milligrams，or almost 3% of it. To confirm that the worms chewing alone was not responsible for the polyethylene breakdown，the researchers made some worms into paste(糊状物) and applied it to plastic films. 14 hours later the films had lost 13% of their massapparently broken down by

4、enzymes(酶) from the worms stomachs. Their findings were published in Current Biology in 2017.,Federica Bertocchini，coauthor of the study，says the worms ability to break down their everyday foodbeeswaxalso allows them to break down plastic. “Wax is a complex mixture，but the basic bond in polyethylene

5、，the carboncarbon bond，is there as well，”she explains. “The wax worm evolved a method or system to break this bond. ” Jennifer DeBruyn，a microbiologist at the University of Tennessee，who was not involved in the study，says it is not surprising that such worms can break down polyethylene. But compared

6、 with previous studies，she finds the speed of breaking down in this one exciting. The next step，DeBruyn says，will be to identify the cause of the breakdown. Is it an enzyme produced by the worm itself or by its gut microbes(肠道微生物)？,Bertocchini agrees and hopes her teams findings might one day help e

7、mploy the enzyme to break down plastics in landfills.

Aidentify other means of the breakdown Bfind out the source of the enzyme Cconfirm the research findings Dincrease the breakdown speed 解析：细节理解题。根据第四段最后两句“The next step. Is it

10、 an enzyme produced by the worm itself or by its gut microbes？”可知，接下来人们需要证实的就是酶是从哪里产生的。选项B“查明酶的来源”与此吻合。,B, It can be inferred from the last paragraph that the chemical might _. Ahelp to raise worms Bhelp make plastic bags Cbe used to clean the oceans Dbe produced in factories in future 解析：推理判断题。根据最后

11、一段第二句“But she expects using the chemical in some kind of industrial processnot simply millions of worms. ”可知，研究人员期望不仅仅能用大蜡螟蠕虫去清理塑料垃圾，也期望在某种工业流程中用这种化学制品，这与选项D中提到的“今后工厂可能生产这种化学制品”吻合。,D, What is the main purpose of the passage？ _ ATo explain a study method on worms.

25、。 (3)以事实为依据：推断一定要以文章所提供的事实为依据，不能凭空想象，这样才能做出合理的推断。,(2018全国，C片段) Languages have been coming and going for thousands of years，but in recent times there has been less coming and a lot more going.
