B．Negative.C．Indifferent. D．Critical.答案：A解析：推理推断题。依据题干中的关键词D.SteveBoland定位到文章第五段，依据该段内容可知，D.SteveBoland认为尽管Z一代很年轻，但这代人务实且主动地规划他们的将来，他们有清楚的设想并情愿努力去实现它；由此可推知，D.SteveBoland对于Z一代是持赞同的看法的，故正确答案为A。7．WhichofthefollowingwordsmaybestdescribetheGenZers?A．Confidentandindependent.B．Visionaryandresponsible.C．Persistentanddown­to­earth.D．Activeandcreative.答案：B解析：推理推断题。依据文章倒数第三段可知，Z一代会主动规划他们的将来并努力实现自己的设想，由此可知，他们是有远见的；又依据倒数其次段的内容，尤其是第一句“Socialissuesarealso...oftheworld”可知，社会问题也是Z一代关注的中心，并且他们认为自己是变更世界的力气，由此可推知Z一代是有责任感的。故正确答案为B。Ⅱ.完形填空Treeshavealwaysheldmuchattractionforpeople.Theyarethe__1__andbiggestlifeformonourplanetandoneofthemostbeautiful.Asadirect__2__withthousandsofyearsofhistory,treesappearinmanyreligionsandhave__3__artistsovertheyears.WhenIwasachildI__4__asciencefictionstorythatmademethinkabouttreesinanewway.Inthestory,__5__fromanadvancedcivilizationcometoourplanetandtheirspaceship__6__inthemiddleofaforest.Thealiens(外星人)havealong__7__withthetreesoftheforestandthenleave,__8__tothinkthattheinhabitants(居民)ofEartharenoble,intelligentandpeaceful.Trees__9__alotaboutbeingpartofacommunityandhowcooperationisbetterforasocietythan__10__.Scientistsareonlyjustbeginningtounderstandhowitall__11__，butwenowknowthattreesgrowingtogethersharealloftheavailableresourceswitheachother.So,strongtreesinagood__12__willsharefoodandwaterwith__13__treesthatreceivelesssunlight.By__14__，acommunityoftreesmakesitselfstronger.The__15__ofgiantredwoodtrees,forexample,growtogetherundertheground.It'sasiftheyare__16__hands.Thismeansthattheyare__17__strongerwhenthereareheavywindsorfloods.Weallacknowledgethattreesare__18__fortheenvironmentandthesurvivalofour__19__.Perhapstheyhaveevenmoreto__20__usinthefuture.树木总是能吸引人们的关注，它们古老又漂亮，是艺术家们的灵感来源；树木之间的团结协作使它们更强大。此处，树木对环境和地球的生存都极其重要。1．A.kindest B．oldestC．heaviest D．fittest答案：B解析：依据第2空后的“thousandsofyearsofhistory”可知，树木是地球上最古老的生命形式。故选B。2．A.link B．leagueC．culture D．agreement答案：A解析：依据第3空前的“treesappearinmanyreligions”并结合语境可推知，树木作为一个干脆的纽带出现在很多宗教里，故选A。3．A.governed B．sponsoredC．inspired D．tricked答案：C解析：依据语境可知，树木也赐予艺术家们灵感。C项意为“赐予灵感”，故选C。A项意为“统治”；B项意为“赞助”；D项意为“欺瞒”。4．A.tookin B．cameacrossC．setaside D．keptup答案：B解析：依据空后的“asciencefictionstory”可知，“我”小时候偶然读到一篇科幻故事。B项意为“偶然发觉”，故选B。A项意为“吸入，理解”；C项意为“留出”。5．A.workers B．researchersC．visitors D．invaders答案：C解析：依据下文中的“anadvancedcivilization”“theirspaceship”以及“Thealiens(外星人)”可知，这里表示的是来自先进文明的访客(visitors)。invader“侵略者”。6．A.lands B．dropsC．flies D．shoots答案：A解析：依据上题的解析以及空后的“inthemiddleofaforest”可知，外来的飞船着陆(lands)在森林中间。7．A.translation B．wordC．cooperation D．conversation答案：D解析：依据第8空后的“think”并结合语境可推知，外星人之所以有这样的相识，是因为他们与森林里的树木进行了一次长谈。故选D。8．A.curious B．happyC．desperate D．grateful答案：B解析：依据下文中的“noble,intelligentandpeaceful”可以推想出那些外星人在离开时，应当是快乐的。故选B。C项意为“无望的”。9．A.get B．knowC．afford D．send答案：B解析：依据第11空后的“treesgrowingtogethersharealloftheavailablerescources”可知，树木在成长的过程中，会共享全部可以得到的资源。由此可以推想出，树木知道(know)自己是整个群体的一部分，并知道合作如何比竞争(competition)对一个群体更好。10．A.regulation B．managementC．competition D．construction答案：C解析：参见上题解析。11．A.learns B．endsC．grows D．works答案：D解析：依据语境可知，这里表示科学家才刚刚起先去了解树木之间的相互合作是怎样运作的。12．A.position B．mannerC．ran
