Almost half of that winds up in landfills(垃圾填埋場), 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(糊狀物) 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(腸道微生物)?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】本文為說明文。文章介紹了一種吃塑料的蟲子大蠟螟，它胃中的酶能夠降解塑料，這為解決塑料污染提供了新的途徑。1.C 【解析】細(xì)節(jié)理解題。根據(jù)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，研究結(jié)果發(fā)現(xiàn)，蠕蟲分解日常食物的能力讓它們可以分解塑料，也就是說它們可以消費(fèi)塑料。故選C。 3.D 【解析】推理判斷題。根據(jù)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. 可以推斷出，Bertocchini希望這種化學(xué)物質(zhì)將來能在工業(yè)生產(chǎn)中使用，而不是僅僅依靠蠕蟲來分解塑料。故選D。4.C 【解析】寫作意圖題。根據(jù)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，有一種新的方法被用于分解塑料。再根據(jù)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希望將這種方法推廣到工業(yè)中。由此可以推知寫作意圖為介紹一種分解塑料的方法。故選C。二、教材與語法填空根據(jù)教材課文內(nèi)容，在空白處填入1個(gè)適當(dāng)?shù)膯卧~或括號(hào)內(nèi)單詞的正確形式。I went into the future because I 1.

Dconversation【解題導(dǎo)語】你以為你對(duì)他的愛很深沉，這是你了解的；你不了解的是，他對(duì)你的愛比你的深沉一萬倍。對(duì)父母的愛，要怎么才說得出口？別太晚。如果沒有勇氣當(dāng)面表達(dá)，就寫封信來告訴他。1B四年前作者發(fā)現(xiàn)父親身患癌癥，癌細(xì)胞已經(jīng)擴(kuò)散，因此，此處指不知道還能活多久。how long you had left是“你還剩下多長時(shí)間”的意思，left用作后置定語。故選B項(xiàng)。2C根據(jù)該空后的people older than me可判斷，作者以為父(母)親垂死這件事只會(huì)發(fā)生在比他年齡更大的人身上。故選C項(xiàng)。3Din doubt意為“懷疑”；in anger意為“生氣地”；in vain 意為“徒勞無益地”；in shock意為“震驚地；吃驚地”。聽到父親患癌這件事，作者當(dāng)然是長時(shí)間地感到震驚。故選D項(xiàng)。刷有所得方法：做完形填空題時(shí)，有些題要注意該空前后的介詞、副詞等。有時(shí)需要分別把選項(xiàng)與前后的介詞、副詞相搭配，再判斷它們搭配后哪個(gè)短語的意思更符合上下文的邏輯。4A根據(jù)下文But there was nothing I could do.可知，作者什么都做不了，由此可推測，此處指作者感到無能為力。powerless意為“無能為力的”；nervous意為“緊張不安的；焦慮的”；lost意為“迷路的；不知所措的”；bored意為“厭煩的；煩悶的”。根據(jù)語境可知選A項(xiàng)。5A根據(jù)下文and take the cancer

rule意為“不成文的規(guī)則”，符合語境。故選D項(xiàng)。10A根據(jù)下文的Youre a man conservative和You keep them to yourself可知，父親很保守，所以這一不成文的規(guī)則阻止了父愛的表達(dá)。prevent意為“阻止；防止”；change意為“改變”；destroy 意為“破壞；摧毀”；transform意為“使改觀；使轉(zhuǎn)化”。故選A項(xiàng)。11Bguarded意為“謹(jǐn)慎的”，結(jié)合下文的You keep them to yourself可知，此處指父親是一個(gè)保守的、對(duì)情感(feelings)謹(jǐn)慎的人。conservative and guarded with your feelings作后置定語，修飾前面的a man。故選B項(xiàng)。illness意為“疾病”；belongings意為“所有物”；opinion意為“觀點(diǎn)”。12B根據(jù)前文對(duì)父親的描述conservative, guarded with your
