Life in the future一、阅读理解阅读下面短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。Plastic-Eating WormsHumans produce more than 300 million tons of plastic every year. Almost half of that winds up in landfills(垃圾填埋场), and up to 12 million tons pollute the oceans. So far there is no effective way to get rid of it, but a new study suggests an answer may lie in the stomachs of some hungry worms. 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 mercial polyethylene shopping bag for 12 hours, and the worms consumed and 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 mass apparently broken down by enzymes (酶) from the worms stomachs. Their findings were published in Current Biology in 2017. Federica Bertocchini, co-author of the study, says the worms ability to break down their everyday food beeswax also allows them to break down plastic. Wax is a plex mixture, but the basic bond in polyethylene, the carbon-carbon 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 pared 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 employ the enzyme to break down plastics in landfills. But she expects using the chemical in some kind of industrial process not simply millions of worms thrown on top of the plastic. 1. What can we learn about the worms in the study?A. They take plastics as their everyday food. B. They are newly evolved creatures. C. They can consume plastics. D. They wind up in landfills. 2. According to Jennifer DeBruyn, the next step of the study is to . A. identify other means of the breakdownB. find out the source of the enzymeC. confirm the research findingsD. increase the breakdown speed3. It can be inferred from the last paragraph that the chemical might . A. help to raise wormsB. help make plastic bagsC. be used to clean the oceansD. be produced in factories in future4. What is the main purpose of the passage?A. To explain a study method on worms. B. To introduce the diet of a special worm. C. To present a way to break down plastics. D. To propose new means to keep eco-balance. 【文章大意】本文为说明文。文章介绍了一种吃塑料的虫子大蜡螟，它胃中的酶能够降解塑料，这为解决塑料污染提供了新的途径。1.C 【解析】细节理解题。根据文章第三段Federica Bertocchini, co-author of the study, says the worms ability to break down their everyday food beeswax also allows them to break down plastic. 可知，研究结果发现，蠕虫分解日常食物的能力让它们可以分解塑料，也就是说它们可以消费塑料。故选C。 3.D 【解析】推理判断题。根据文章最后一段But she expects using the chemical in some kind of industrial process not simply millions of worms thrown on top of the plastic. 可以推断出，Bertocchini希望这种化学物质将来能在工业生产中使用，而不是仅仅依靠蠕虫来分解塑料。故选D。4.C 【解析】写作意图题。根据文章第一段最后一句So far there is no effective way to get rid of it, but a new study suggests an answer may lie in the stomachs of some hungry worms. 可知，有一种新的方法被用于分解塑料。再根据最后一段最后一句But she expects using the chemical in some kind of industrial process not simply millions of worms thrown on top of the plastic. 可知，Bertocchini希望将这种方法推广到工业中。由此可以推知写作意图为介绍一种分解塑料的方法。故选C。二、教材与语法填空根据教材课文内容，在空白处填入1个适当的单词或括号内单词的正确形式。I went into the future because I 1.

Dconversation【解题导语】你以为你对他的爱很深沉，这是你了解的；你不了解的是，他对你的爱比你的深沉一万倍。对父母的爱，要怎么才说得出口？别太晚。如果没有勇气当面表达，就写封信来告诉他。1B四年前作者发现父亲身患癌症，癌细胞已经扩散，因此，此处指不知道还能活多久。how long you had left是“你还剩下多长时间”的意思，left用作后置定语。故选B项。2C根据该空后的people older than me可判断，作者以为父(母)亲垂死这件事只会发生在比他年龄更大的人身上。故选C项。3Din doubt意为“怀疑”；in anger意为“生气地”；in vain 意为“徒劳无益地”；in shock意为“震惊地；吃惊地”。听到父亲患癌这件事，作者当然是长时间地感到震惊。故选D项。刷有所得方法：做完形填空题时，有些题要注意该空前后的介词、副词等。有时需要分别把选项与前后的介词、副词相搭配，再判断它们搭配后哪个短语的意思更符合上下文的逻辑。4A根据下文But there was nothing I could do.可知，作者什么都做不了，由此可推测，此处指作者感到无能为力。powerless意为“无能为力的”；nervous意为“紧张不安的；焦虑的”；lost意为“迷路的；不知所措的”；bored意为“厌烦的；烦闷的”。根据语境可知选A项。5A根据下文and take the cancer out可知，此处指作者希望可以进入父亲的身体拿走癌细胞。reach into意为“伸进；伸入”；turn to意为“转向；求助于”；stand by意为“袖手旁观；支持”；look into意为“调查”。故选A项。6B根据该空后面的You reacted well to treatment and youre still
