参考答案UNIT1单元提能强化练Ⅰ.【语篇导读】本文是一篇记叙文。FawnSharp通过一次搭乘直升机飞行的经验相识到了冰川溶化和环境污染问题的严峻性;同时JenniferWrenAtkinson确定给学生开设课程,教学生如何面对环境污染,让更多的学生关注环境问题。1.C推理推断题。通读第一段可知,FawnSharp在一次直升机飞行中意识到气候改变导致了冰川溶化。由此可推知,作者在第一段中提及FawnSharp的例子是为了引出下文气候改变导致环境问题的话题。2.B细微环节理解题。依据其次段内容可知,由于气候改变引起环境问题,她产生了在高校开设环境爱护课程的想法。由此可知,Atkinson开设课程的目的是让学生更加关注环境问题。3.B词义揣测题。依据画线词上文“noeasyfix”以及下文的“they’regoingtobedealingwithitfortherestoftheirlives”可知,这是一个特别困难的问题,以至于学生们要用他们的余生来解决它。4.C推理推断题。依据倒数第三段“Sixmonthsintothework...discusshisconcernsaboutachangingclimate.”可知,Dillon在环保组织做了六个月志愿者之后,他认为在Atkinson的课堂上他可以探讨他对气候改变的担忧。由此可推知,Atkinson的课激励Dillon更多地参与到环境爱护中。【语篇导读】本文是一篇说明文。本文主要介绍了一种新型微型机器人,它可以帮助清理污染水道的塑料碎片。5.C细微环节理解题。由其次段中的“Whenthesunlightshinesonthem,theycanswiminaspecificdirection;whenthesunlightdisappears,theystopmoving.”可知,新型微型机器人是由阳光驱动的。故选C项。6.D细微环节理解题。由第三段中的“Abouttenyearsago,henoticed...easilydegrade,whichisabigproblem.Therefore,Pumerachosetofocusontheproblemofwaterpollutioncausedbymicroplastic.”可知,微塑料不简单降解,无处不在。微塑料污染给环境带来了挑战,这是吸引Pumera从事该项探讨的缘由之一。由此可知,微塑料污染激发了Pumera设计微型机器人的灵感。故选D项。7.D细微环节理解题。由第四段中的“Theresearcherstestedthemicrorobotsonfourtypesofplasticinthelab.Afteraweek,allfourbegandegrading,losingbetween0.5and3percentoftheirweight,whichindicatedtheywerebreakingdown.”可知,仅一周时间,塑料的重量减轻,这说明微型机器人可以在某种程度上分解塑料。故选D项。8.B推理推断题。由最终一段中的“Buthethinksthatthesechallengescanbeovercome.Someday,themicrorobotswillplayabigroleinaworldwidecleanupeffort.”可知,Pumera认为,探讨中的这些挑战是可以克服的,微型机器人在将来将发挥重要作用。由此可知,他对将来的探讨很有信念。故选B项。Ⅱ.【语篇导读】本文是一篇说明文。文章主要说明白漫步对人的一些好处,以及如何选择漫步路途的建议。从对心脏的好处到对整体的欢乐,漫步是特别好的。文章最终提倡人们起先漫步。1.F依据上文“Humanbodieswereactuallydesignedforwalking,awonderfulformofexerciseatnocost.”可知,本句承接上文接着说明漫步的好处。故F项符合上下文语境。2.D结合下文“Askyourself...Knowingyourgoalswillhelpyoudecideonthetypeofwalkyouwanttodo.”可知,本句是在说明要带着目标漫步,下文一系列设问句是在说明如何找寻目标。故D项符合上下文语境。3.B依据上文“Callupyourfriendsandschedulewalkswiththemifsocializingisyouraim.”可知,假如想要和挚友一起漫步社交,那么须要了解他们喜爱去哪里漫步。故B项符合上下文语境。4.G依据下文“Manylargecitieshaveincrediblegardensandparksthatincludequietwalkingtrailsgettingyouoffthebeatenpath.”可知,本段是在说明假如想一个人漫步,可以选择去大城市的花园或公园里。故G项符合上下文语境。5.A依据上文“Fromthebenefitstoyourhearttoyouroverallhappiness,walkingisjustplaingoodforyou.”并且本段为文章最终一段,有总结上文的作用,上文提到了漫步的好处和选择,那么此处应当是提倡人们起先漫步。故A项符合上下文语境。Ⅲ.【语篇导读】本文是一篇夹叙夹议文。文章通过讲解并描述一个参与拼字竞赛的小女孩因为选择诚恳而输掉竞赛的故事告诫读者,“在别人不知情的状况下你选择如何做”才是真正品性的写照。1.D依据下文“thejudgeswerenotsurewhethershespelledtherightword”可知,评委无法确定她的拼读是否是正确的。由此可知她的声音很温柔,评委没有听清晰。2.A依据上文“Theytalkeditover”可知,评委们探讨以后最终确定问她刚刚说
