4、er pollution, I'd like you to look at a study ________ (conduct) in Australia in 2012. 答案：conducted　study與conduct之間為被動(dòng)關(guān)系，且設(shè)空處表示動(dòng)作已完成，故用過(guò)去分詞作后置定語(yǔ)。句意：回到水污染問(wèn)題，我想讓你們看一下2012年在澳大利亞進(jìn)行的研究。 3．(2016·江蘇高考)In art criticism, you must assume the artist has a secret message ________ (hide) within the work. 答案：h

5、idden　設(shè)空處在句中作定語(yǔ)，message與hide之間為被動(dòng)關(guān)系，且設(shè)空處表示動(dòng)作已完成，故用過(guò)去分詞形式。句意：在藝術(shù)評(píng)論中，你必須假定藝術(shù)家在作品中有一定的隱含信息。 4．(2014·安徽高考)While waiting for the opportunity to get ________ (promote), Henry did his best to perform his duty. 答案：promoted　邏輯主語(yǔ)Henry和promote之間是被動(dòng)關(guān)系，故使用過(guò)去分詞。句意：亨利在等待獲得升職機(jī)會(huì)的同時(shí)，盡力做好自己的本職工作。 課堂合作探究 過(guò)去分詞是非謂語(yǔ)動(dòng)詞

24、Almost half of that winds up in landfills， 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 greate

25、r 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 broke down about 92 milligrams, or almost 3% of it. To confirm that the worms' chewing alone was not responsible

26、 for the polyethylene breakdown, the researchers made some worms into paste 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 Berto

27、cchini, 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 complex 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 t

28、o 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 with previous studies, she finds the speed of breaking down in this one exciting. The next st

29、ep, 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 team's findings might one day help employ the enzyme to break down plastics in landfills. But she expects using the chemica

30、l in some kind of industrial process—not simply “millions of worms thrown on top of the plastic.” 篇章導(dǎo)讀：本文是一篇說(shuō)明文。最新科學(xué)研究發(fā)現(xiàn)大蠟螟幼蟲(chóng)能利用體內(nèi)的酶來(lái)分解塑料，這是一種分解塑料的新方法。 1．What can we learn about the worms in the study?

A．help to raise worms B．help make plastic bags C．be used to clean the oceans D．be produced in factories

33、 in future 答案：D　推理判斷題。根據(jù)最后一段第二句可知，她希望通過(guò)某種工業(yè)生產(chǎn)程序使用這種化學(xué)物質(zhì)，而不是簡(jiǎn)單地“把數(shù)百萬(wàn)條蟲(chóng)子扔在塑料上”。由此可推知，將來(lái)這種化學(xué)制品可能由工廠生產(chǎn)。故選D。 4．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

36、he sea are already being planned. A company in the Netherlands called DeltaSync thinks that the sea cities will save the world, with more than one in ten people living in them. They say sea cities solve many problems the world faces in the 21st century, like not having enough land, more and more pe

37、ople needing homes, fossil fuels (化石燃料) running low and the increasingly serious problems caused by floods. DeltaSync says building cities in the desert is not possible because there is not enough water and developing ways for people to live in space is still too expensive. So they believe the answ

38、er is our ocean, which covers over two thirds of the Earth's surface. Their plans for floating areas include using algae to produce fuel and food. More than a quarter of the land in the Netherlands already lies underwater and scientists there have spent years trying to find ways to deal with it. In

39、 the city of Rotterdam they already have floating homes. Bart Roeffen from DeltaSync says, “We have plans for neighbourhoods including roads and, in the end, I believe we can build floating cities on the sea.” 篇章導(dǎo)讀：本文是一篇說(shuō)明文，主要介紹了人們想要在海上建造城市的計(jì)劃，并且在某些地方，漂浮城市的計(jì)劃已經(jīng)在進(jìn)行。科學(xué)家們認(rèn)為這能為不斷增長(zhǎng)的人口提供更多居住地，荷蘭的一家公司也提
