unit 2 cloning reading課時(shí)作業(yè).閱讀理解(2017河北衡水中學(xué)五調(diào))jeremy kerr，a researcher at the university of ottawa in canada，and his colleagues analyzed more than 400,000 observations of bumblebee species collected in north america and europe from 1975 to 2010.when the researchers recorded the locations of these bee populations，they found that many of the 67 species analyzed were moving northward from their southern limits while the northern edges of the bees ranges are staying in place.what it results in is obvious.bees have been paid more attention to in recent years，with populations of honeybees and bumblebees obviously declining in some parts of europe.previously，attention on the decline of bee populations has focused on causes including habitat loss，pesticide use and the spread of bee parasites(寄生蟲).but the work by kerrs team found something different.“for every species，there is one or two species declining and others that are not moving at all，” says kerr.this shift has also been observed in other species，such as butterflies.but due to a new causethe rise of temperatures instead of total pesticide use，a change in land use or parasites，bumblebeesunlike butterflieshave failed to extend the northern boundaries of their ranges into the territory that is now habitable for them，so bumblebee species across europe and north america are declining rapidly，the latest study led by kerrs team finds.“our data suggests that the new factor plays a leading，or perhaps the leading，role in this trend，” says kerr.“this study shows that a fourth factor is also beginning to affect it.it is likely that the combined stresses from all of these pressures will have destructive impacts on bumblebees in the nottoodistant future，” says dave goulson，a bee researcher at the university of sussex，brighton，uk.exactly what can be done to help bumblebees is not clear.kerrs team suggests that relocating colonies might be an answer but goulson says that because the insects are mobile they are capable of moving northwards if there is suitable habitat available.1.what does the move of the bees southern limits lead to?a.the birth of new bee species.b.the rise of the bees population.c.the evolution of the bees.d.the reduction of the bees habitat.2.whats the new cause of bee populations declining according to kerr?a.habitat loss.b.pesticide use.c.climate change.d.the spread of bee parasites.3.which statement may goulson agree with?a.relocating bumblebees isnt much good.b.the findings of kerrs study are doubtful.c.the future of bumblebees is still promising.d.knowing bumblebees living habits is the most urgent.4.what kind of writing is this passage?a.a book review. b.an announcement.c.a scientific report. d.an official report.完形填空(2018浙江“五校聯(lián)考”)for me personally，i could write for days about many different situations where adversity(逆境) 5 my life.now let me tell you one experience where i almost let

analyzed were moving northward from their southern limits while the northern edges of the bees ranges are staying in place.what it results in is obvious.”可知蜜蜂由南向北遷徙會(huì)導(dǎo)致它們棲息地的減少。故選d。2.c細(xì)節(jié)理解題。根據(jù)第三段第三句中的“but due to a new causethe rise of temperatures instead of total pesticide use.”可知蜜蜂種類下降的新原因是溫度的上升，即氣候變化。故選c。3.a推理判斷題。根據(jù)最后一段的內(nèi)容可知dave goulson認(rèn)為因?yàn)榇簏S蜂是具有流動(dòng)性的，只要有合適的棲息地，它們還是能夠向北遷徙，所以重新安置大黃蜂并非一個(gè)好辦法。故選a。4.c推理判斷題。本文是一篇關(guān)于蜜蜂數(shù)量減少的原因的調(diào)查報(bào)告，屬于科學(xué)報(bào)告。故選c。.語(yǔ)篇解讀 這是一篇夾敘夾議文。作者通過(guò)自己的親身經(jīng)歷告訴我們：人生中的逆境可能會(huì)讓你活得更好。5.apromote促進(jìn)，提升；influence影響；destroy破壞；prevent阻止。句意為：就我個(gè)人而言，我可以連續(xù)幾天寫出大量的關(guān)于逆境提升生活的不同情境。故選a。6.csuffer遭受；escape逃脫；win獲勝；work工作。句意為：讓我告訴你一個(gè)我?guī)缀醣欢蜻\(yùn)戰(zhàn)勝的經(jīng)歷。從下文的冰雪壓塌了“我們”的工作室，使“我們”無(wú)法正常工作的經(jīng)歷可知“我”幾乎被擊敗。故選c。7.dawkward難對(duì)付的，棘手的；awesome令人敬畏的；agreeable令人愉快的；awful糟糕的，可怕的。根據(jù)下文工作室的屋頂被冰雪壓塌可知，這是一個(gè)糟糕的冬天。故選d。8.csize大??；height 高度；weight重量；temperature溫度。根據(jù)常識(shí)及句意可知是冰雪的重量讓屋頂因承受不住而倒塌。故選c。9.acollapse倒塌；limit限制；press按，壓；strike撞擊，敲響。根據(jù)下一句中的“fall down”可知選a。10.abefore在之前；unless除非；although盡管；when當(dāng)時(shí)。句意為：在它倒塌之前，我們上了屋頂。故選a。11.dreplace代替；reduce減少；recycle 循環(huán)；remove移走，除去。因?yàn)槲蓓斢斜?，所以上屋頂?shù)哪康木褪浅ニ鼈?。故選d。12.bworthwhile值得的；tough 艱苦的，困難的；rewarding值得的；annoying討厭的，惱人的。句意為：當(dāng)你在5英尺厚的冰和零下20攝氏度情況下，這是很難做到的。故選b。13.cexamine檢查，考試；test測(cè)試；secure保護(hù)，使安全；restore歸還，修復(fù)。句意為：我們讓一個(gè)搭檔來(lái)幫助我們通過(guò)支撐來(lái)固定屋頂以使其安全。故選c。14.dsomething某物，某事；enough充足；all一切； nothing沒(méi)有什么東西。句意為：最后，我們沒(méi)有什么能做的(來(lái)阻止屋頂?shù)牡顾?。故選d。15.b句意為：我們從工作室搬走了我們的很多產(chǎn)品和工具，但我們也失去了很多。前后表轉(zhuǎn)折，故用but。16.cvain徒勞的，無(wú)結(jié)果的；valid有效的，正當(dāng)?shù)模?disastrous災(zāi)難性的，損失慘重的； treasured寶貴的，珍貴的。因?yàn)橛泻芏鄸|西沒(méi)有搬出來(lái)，所以這是一次損失慘重的經(jīng)歷。故選c。17.cdisplay展示； arrange安排；pile堆放，放置； present呈現(xiàn)。句意為：我們不能工作，因?yàn)槲覀儙缀醢阉械牟牧隙言谝粋€(gè)我們沒(méi)有使用的建筑物里。故選c。18.bpredict預(yù)言，預(yù)測(cè)；conduct引導(dǎo)，帶領(lǐng)，實(shí)施；instruct

organize組織；reserve 儲(chǔ)備，保留。后半句說(shuō)現(xiàn)在的工作區(qū)比以前的更好，可推斷出是重新設(shè)計(jì)的，因此選b。22.ddesperately絕望地，不顧一切地；hopefully有希望地；eventua
