24、CC【解析】本文是一篇说明文，介绍了一架环球旅行的太阳能飞机从夏威夷飞往加利福尼亚州。28. 词义猜测题。根据画线词前的Asolarplaneonaround-the-worldjourneyhasreachedthepointofnoreturnoverthePacificOceanafterdepartingHawaii,"可知，一架环球旅行的太阳能飞机在离开夏威夷后已经到达了太平洋上空的不可返回点，现在它要么在加利福尼亚要么就完蛋了，由此可知画线词词义为“（环球旅行）成功或失败”，故A项正确。29. 细节理解题。根据第二段中的“accordingtothewebsitethat

25、'recordingthejourneyofSolarImpulse2."根据网站上飞机旅程的记录可知，这架太阳能飞机叫SolarImpulse2，故C项正确。30. 细节理解题。根据倒数第二段中的WhenfirstattemptingtoflyfromNanjingtoHawaii,thecrewhadtodiverttoJapanbecauseofunfavorableweatherandadamagedwing."可知，这架太阳能飞机在日本停留一个月是天气不好，一侧机翼也损坏了，故C项正确。31. 主旨大意题。根据第一段Asolarplaneonaround-

26、the-worldjourneyhasreachedthepointofnoreturnoverthePacificOceanafterdepartingHawaii,andnowit'Californiaorbust.”（句意参考28题解析），以及文章大意可知，本文介绍了这架太阳能飞机从夏威夷飞往加利福尼亚州，故C项正确。DScientistsinWesternAustraliaclaimtohavemadeanewdiscoverytheyhavefoundgoldintheleavesandtwigsoftrees.Theresearchersbelievethatthetree

34、声称有了一项新发现他们在树叶和树枝中发现了金子，这一发现被描述为世界上第一个类似的发现。但作者认为第一次在植物中发现金属微粒的说法可能是不正确的，因为中国人几千年前就发现了这种现象。32. 纟田节理解题。由第一段Theresearchersbelievethatthetreessuckupthegoldfromdeepunderground,over30metresdown.”可知，研究人员相信这些树能从30米以下的地下深处吸收黄金。所以从第一段我们可以知道树木能从地下深处吸收金子。故B选项正确。33. 纟田节理解题。由第一段ThegoldisfoundusingaspecialX-rayma

35、chineownedbyanAustraliangovernmentagency"可知，黄金是由澳大利亚政府机构所有的一台特殊的X光机检测到的。所以科学家用特殊的X射线来寻找树叶中的金子。故C选项正确。34. 纟田节理解题。由第二段"AncientChinesewisdomunderstoodtheconnectionbetweenplantsandthepreciousstonesandmineralsunderneaththem.Theyusedplantlifetofindmineralsandthatwasthousandsofyearsago”可知，中国古代积累的

36、知识很早就介绍了植物和其下面的宝石与矿物之间的联系。他们用植物来寻找矿物，那是几千年前的事了。所以中国古代人民首先发现植物和矿物之间有联系。故A选项正确。35. 推理判断题。由最后一段Evenmoreimportantly,inthe1,000s,SuSongdescribedhowcopper,gold,silver,leadandtinwereobservedandtakenfromcertainplants.Thesewereamazingscientificdiscoveries.Meanwhile,thisknowledgewasunknownintherestoftheworldu

37、ntilabout1,600.ThiswaswhenaBritishmanrealisedthatoaktreesgrewlargerandgreenerwheretherewasalum阴矶）intheground.MaybeancientChinesehasmoreknowledgetoteachmodernscientists."可知，更重要的是，在11世纪，科学发现。与此同时，直到大约1600年以前，这种知识在世界其他地方还不为人所知。这时，一位英国人意识到，在有明矶的地方，橡树更大、更绿。也许古代中国人有更多的知识来教授给现代科学家。所以最后一段仍然在说明中国人很早就发现了

38、植物中含有金属微粒的现象。故最后一段的目的是提供更多的证据来支持作者的观点。故B选项正确。第二节（共5小题；每小题2分，满分10分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。VoluntourismNewTrendinTravelVolunteeringtohelppeopleinneedcombinedwithtravellingtofarawayplacesisanewtrendinthetravelindustry.Itiscalledvoluntourism.36.Ontheotherside,theyvolunteertohelpothersw

43、nces.【答案】36.G37.E38.B39.C40.D【解析】本文属于议论文，讲述义工旅行最近很受大家的欢迎，不同的人对此抱有不同的态度和目，有利也有弊。36. 根据后一句Ontheotherside,theyvolunteertohelpotherswhoarenotaswelloffastheyare.”可知，另一方面，志愿者帮助不如他们富裕的人。所以前句讲述义工旅行的方面，人们去其他地方旅游，学习外语和新的文化，增加阅历（G选项），另一方面帮助别人，承接下文，切题，故选G。37. 根据前一句Recentstatisticsshowthatinthepastfewyearsvolunt

44、ourismhasbeenoneofthefastest-growingareasoftourism可知，最新的数据显示，在过去的几年里，义工旅游是旅游业中增速最快的方面之一，全世界超过160万志愿者在外国进行志愿服务（E选项），具体是对前一句的说明，切题，故选E。38. 根据本段后文，讲述了不同人选择义工旅游的原因，公益旅游的原因有很多种（B选项），是对本段的总结，切题，故选B。39. 根据后一句Theythinkitisacheapwayoftravellinganddon'reallywanttogetinvolvedinhardwork.”可知，他们把义工旅行当作是一种廉价的旅

45、游，并不想真正参与到艰苦的工作中去，很多人并没有正确认识公益服务这一概念（C选项），与后一句切题，故选C。40. 根据前一句Critics（评论家）saythatifpeoplereallywanttohelpthoseinneedtherearemanyopportunitiesintheirowncommunitytodothis.”以及后一句Travelexpertsalsopointoutthatinsomecasesvoluntouristsaremadeuseofbyorganizationsthatsetupthetrips?可知，本段主要阐述志愿者旅行方式的弊端，比如要帮助别人

46、，自己身边就有很多机会，选择义工旅行很可能被机构组织利用，志愿者们可能没有足够的技能从事公益服务（D选项），切题，故选D。第三部分英语知识运用（共两节，满分45分）第一节完形填空（共20小题；每小题1.5分，满分30分）阅读下面短文，从短文后各题所给的四个选项（A、B、C和D）中，选出可以填入空白处的最佳选项。AlwayswishedtheEarthhadasecondmoon?Thenyouwillbe41tohearthattheChengduAerospaceScienceInstitutehasplanstolaunchmultipleminimoonsoverthenextfewye
