参考答案UNIT1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历认识到了冰川融化和环境污染问题的严重性;同时JenniferWrenAtkinson决定给学生开设课程,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推理判断题。通读第一段可知,FawnSharp在一次直升机飞行中意识到气候变化导致了冰川融化。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变化导致环境问题的话题。2.B细节理解题。根据第二段内容可知,由于气候变化引起环境问题,她产生了在大学开设环境保护课程的想法。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词义猜测题。根据画线词上文“noeasyfix”以及下文的“they’regoingtobedealingwithitfortherestoftheirlives”可知,这是一个十分困难的问题,以至于学生们要用他们的余生来解决它。4.C推理判断题。根据倒数第三段“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的课堂上他可以讨论他对气候变化的担忧。由此可推知,Atkinson的课鼓励Dillon更多地参与到环境保护中。【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细节理解题。由第二段中的“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细节理解题。由第三段中的“Abouttenyearsago,henoticed...easilydegrade,whichisabigproblem.Therefore,Pumerachosetofocusontheproblemofwaterpollutioncausedbymicroplastic.”可知,微塑料不容易降解,无处不在。微塑料污染给环境带来了挑战,这是吸引Pumera从事该项研究的原因之一。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推理判断题。由最后一段中的“Buthethinksthatthesechallengescanbeovercome.Someday,themicrorobotswillplayabigroleinaworldwidecleanupeffort.”可知,Pumera认为,研究中的这些挑战是可以克服的,微型机器人在未来将发挥重要作用。由此可知,他对未来的研究很有信心。故选B项。Ⅱ.【语篇导读】本文是一篇说明文。文章主要说明了散步对人的一些好处,以及如何选择散步路线的建议。从对心脏的好处到对整体的快乐,散步是非常好的。文章最后倡导人们开始散步。1.F根据上文“Humanbodieswereactuallydesignedforwalking,awonderfulformofexer
