Now,researchers at The University of Queensland have found a species of worm with a taste for polystyrene could be the key to plastic recycling.The superworm can eat through polystyrene, thanks to a bacterial enzyme in their gut.To study how superworms react to purely plastic food, researchers broke up 135 of the creatures into three teams:one was fed only wheat bran,another was fed only plastics,and the third was given nothing "We found the bran-fed worms have been significantly healthier than the plastic-fed or hungry worms,more than doubling their weight over the three weeks they have been observed.Though the plastic-fed worms made less impressive gains,they still put on more weight than the hungry worms,"Dr Rinke said."This suggests the worms can get energy from plastics,most likely with the help of their gut microbes(微生物.” Researchers used a technique called metagenomics to find several encoded enzymes with the ability to reduce polystyrene.The long-term goal is to engineer enzymes to reduce plastic waste in recycling plants "Superworms are like mini recycling plants.eating the polystyrene and then feeding it to the bacteria in their gut,"Dr Rinke said.It's hoped this bio-upcycling will promote plastic waste recycling and reduce landfills.Researchers said they aim to grow the gut bacteria in the lab and further test its ability to reduce polystyrene.Then they can look into how to improve this process to a level required for an entire reeyeling plant 篇章导读：本文是一篇说明文。文章主要介绍了一种对聚苯乙娇有食欲的蠕虫可能是塑料回 收的关键。 亨学科网书城 品牌书店·知名数辅·正版资源 b.zxxk.com 您身边的互联网+教辅专家 1.What problem do the statistics in Paragraph 1 indicate? A.Landfills are poorly managed. B.Plastics are recycled at a very low rate. C.Many plastic containers are of poor quality. D.It takes a long time for plastic waste to break up. 答案：B推理判断题。根据第一段中的“According to a recent report.being recycled.(根据 最近的一份报告，仅在美国，2018年就有2,700万吨塑料进入垃圾填埋场，但只有310万 吨被回收利用。世界范围内的数据同样糟糕，只有9%的塑料被回收利用。)”可推知，第一 段中列出的数据是为了说明塑料回收率很低。故选B。 2.How do researchers conduct the study on superworms? A.By collecting data B.By making a comparison C.By introducing a concept. D.By referring to a previous study 答案：B推理判断题。根据第二段中的“To study how.was given nothing.(为了研究超级蠕 虫对纯塑料食物的反应，研究人员将135只超级蠕虫分成三组：一组只喂麦麸，另一组只喂 塑料，第三组什么都不喂。)”可推知，研究人员通过分组对比对超级蠕虫进行研究。故选B。 3.What can we infer from Dr Rinke's words? A.Plastic-fed worms had a decline in weight B.Superworms showed little interest in wheat bran. C.Superworms could survive on only eating polystyrene. D.Bran-fed worms had a longer lifespan than plastic-fed worms. 答案：C推理判断题。根据第三段中的“Though the plastic--fed worms made less impressive gains,.they still put on more weight than the hungry worms(虽然塑料喂养的蠕虫没有那么明显 的增长，但它们仍然比饥饿的蠕虫增加了更多的体重)”可推知，超级蠕虫只靠吃聚苯乙烯就 能存活。故选C。 4.What do researchers plan to do? A.Conduct experiments on other worm species. B.Improve gut bacteria's ability to reduce plastics. 2 亨学科网书城 品牌书店·知名数辅·正版资源 b.zxxk.com 您身边的互联网+教辅专家 C.Apply the bio-upcyeling technology to recycling plants. D.Raise superworms in a big way to solve plastic pollution. 答案：C推理判断题。根据最后一段中的“It's hoped this bio-.upcycling will promote plastic waste recycling and reduce landfills.(人们希望这种生物升级能促进塑料垃圾的回收利用，减少 垃圾填埋场。)”及“Then they can look into how to improve this process to a level required for an entire recycling plant.(然后，他们可以研究如何将这一过程提高到整个回收厂所需的水平。)” 可推知，研究者们打算将生物循环技术应用于回收工厂。故选C。 ‖七选五 Researchers from Harvard University's Wyss Institute have made "robotic shorts"that can help people use less energy when they walk or run. 1.A motor on the user's back pulls cables connected to the laps. In the past,such devices have focused only on helping people walk or run.but not both,since walking and running use different hip (movements.But a computer on the shorts can tell which way the user is moving.2. The researchers found that the main benefit of the shorts was reducing the energy people needed to walk or run.In tests,the energy needed for walking was reduced by 9.3 percent.3.Less energy was needed both on flat ground and on hills The researchers said that while the shorts weigh about 5 kilograms,moving with them makes users feel lighter.The tests showed that a person walking with the device would feel 4 kilograms lighter, 4 The team now also wants to make the device itself 40 percent lighter.They hope the shorts can help people in danger of injury at work and those who want to improve their physical performance. 5 Conor Walsh,who helped lead the study,says he hopes such devices will be available to everyone in the future.
