B．topurchaseahouseC．topredictdisasters D．toaccumulatewealth解析：選B詞義猜測(cè)題。根據(jù)第三段畫(huà)線部分之前的內(nèi)容“ContourCraftingcouldgreatlydecreasethecostofhomeowning,makingitpossibleformillionsofdisplacedpeople...”中的“decreasethecostof”并結(jié)合選項(xiàng)可推知，由于建房成本大大降低了，所以許多人可以買(mǎi)得起房子了。因此B項(xiàng)與畫(huà)線部分意思相近。3．Thenewconstructiontechnologycansatisfytheneedsof________.A．low-incomeresidentsB．peopleatdifferentincomelevelsC．middle-incomepeopleD．wealthyimmigrants解析：選B推理判斷題。根據(jù)第四段最后一句“Asaresult,itcouldbeidealtoprintoutexpensivehomesaccordingtocustomers'demands.”可知，它可以根據(jù)客戶(hù)的需要建設(shè)出豪宅。由此結(jié)合第三段第一句可推知，新的建設(shè)技術(shù)能滿足不同收入水平的人們的需求。4．WhatinfluencewillContourCraftinghaveonconstructionindustry?A．Manyconstructionworkerswilllosejobs.B．Professionalswillbehiredtomakerobotbuilders.C．Moreruralpeoplewillengageinconstruction.D．Constructionworkerswillupdatetheirskills.解析：選D推理判斷題。根據(jù)最后一段最后兩句可知，隨著巨型機(jī)器人技術(shù)的發(fā)展，在建筑業(yè)會(huì)有新的就業(yè)機(jī)會(huì)，而建筑工人的主要任務(wù)是維護(hù)機(jī)器。由此可推知，建筑工人將會(huì)更新自己的技能。BSciencefictionwriterscreateimaginaryworlds.Thewaythingsworkinyourimaginaryworldswillbebasedonactualscience.Soit'simportantforyoutobefamiliarwiththescientificprinciplesandinventionsthatarerelatedtoyourcreation.Forexample,ifyou'rewritingabouthumanlivingonaplanetwithzerogravity,thenyouneedtoknowtheeffectsofzerogravityonthehumanbody.Thenyouhavetofigureouttheexactrulesofyourimaginaryworlds.Andyouhavetofollowthem.IfhumansareabletobreatheunderwaterinChapter1,yourcharactercan'tdrowninaswimmingpoolinChapter3.Theissuehereismaintainingyourreaders'trust.Thatmeansthereaderiswillingtopretendalongwithyou.Ifyoustartoutwithanordinarydetectivenovelandthenthrowinsomeonebreathingunderwaterinthe6thchapter,youwillpullthereadersoutoftheirimagination.Thesamethinghappensifyouchangetheruleshalfway.Partofyourpreparationworkforthenovelistomapoutitsworldsingreatdetail.Youshoulddecidethefollowingissues:thehistoryoftheworld,thegeography,whatpossibilitiesitoffers,howeverythingworksinthisnewreality,andhowallofthesefactorsaffectthewayyourcharactersthink,feel,andreacttothings.Youdon'thavetotellyourreadersalltherulesinthefirstchapter.Butyouhavetoletreadersknowenoughtounderstandwhat'sgoingon.Thisalsoallowsyoutoworkoutlogicalproblemsandcontradictions(矛盾)beforeyoustartwriting.Whenyouarewriting,remembertomakeitfeelreal.Youareinvitingreaderstovisitanewworld.Theywillwanttobeabletosee,hear,feel,smell,andeventastewhatit'slike.Whetheryournovelisaboutaworldwithoutdiseaseoranundiscoveredplanet,helpyourreadersfeellikethey'reactuallythere.語(yǔ)篇解讀：很多人對(duì)科幻小說(shuō)充滿興趣，你是否想寫(xiě)科幻小說(shuō)呢？5．What'stherelationshipbetweenactualscienceandsciencefiction?A．Sciencefictionpromotesthedevelopmentofactualscience.B．Sciencefictionoftenreflectsthedevelopmentofactualscience.C．Actualsciencelimitstheimaginationdescribedinsciencefiction.D．Actualscienceprovidesbasicprinciplesforsciencefiction.解析：選D推理判斷題。從第一段的“Thewaythingsworkinyourimaginaryworldswillbebasedonactualscience.”即幻想世界事物產(chǎn)生的過(guò)程和方式基于現(xiàn)實(shí)科學(xué)，可知D項(xiàng)正確。6．Thesecondparagraphismainlydevelopedby________.A．makingcomparisonsB．givingexamplesC．followingthetimeorderD．a(chǎn)nalyzingcauses解析：選B寫(xiě)作手法題。第二段主要是通過(guò)舉例的方式闡述了觀點(diǎn)。7．WhichofthefollowingstatementsisTRUE?A．Itisnecessarytodosomescientificexperimentsbeforewritingsciencefiction.B．Itismoredifficulttowritesciencefictionthanordinarydetectivenovels.C．Readersofsciencefictionactuallypretendthewriters'rulesaretrue.D．Itisgreattoleavesomecontradictionsinyoursciencefiction.解析：選C推理判斷題。從第二段的“Theissuehereismaintainingyourreaders'trust.Thatmeansthereaderiswillingtopretendalongwithyou.”可知C項(xiàng)正確。8．Thetargetreadersofthepassageare________.A．youngscientistsB．sciencefictionwritersC．collegestudentsD．professionaljournalists解析：選B推理判斷題。文章多處出現(xiàn)第二人稱(chēng)，如“Thewaythingsworkinyourimaginaryworlds...”，由此可推斷出作者在與寫(xiě)科幻小說(shuō)的人交流。CThesummerbeforemysenioryearofhighschool,Iwaseatinginacafeteriawithsomeotherhighschoolstudents,andonegirlaskedme,“Doyouliveinateepee(圓錐形帳篷)？”Itwassuchasillyquestionthat,atfirst,Ithoughtshewasjoking!Isaid,“Areyouserious？”Shesaid,“Oh,wait,I'msorry.IsthatsomethingIshouldn'task？”Shewasn'ttryingtoberude,soitdidn'tbotherme.Ijustsaid,“No,Ihaveahousewithelectricityandrunningwater.I'mnotdisconnectedfromtheworld！”Butthetruthis,Ididgrowupdifferently.I'maNativeAmerican,andI'mfromareservationinCalifornia.Areservationisaplacethat'sreservedforNativeAmericantribes(部落)bythefederalgovernment.Peopleoftenhavemisconceptionsaboutwhatlivingonareservationmeans.Inreality,though,mylifeprobablylooksalotlikeyours.Buttherearewaysthatmylifehasbeendifferent.Thereservationisanhourfromtown,andthere'sabigconnectiontotheland.Ourhouseissurroundedbyamountain,ariver,andafarm.Wehave23animalsincluding10chickens.It'snotjustforshow!Wecollecteggsfromthechickens,usemanure(糞肥)fromtheanimalstofertilizesoil,andpickfruitsandvegetablesfromourgarden.I'vealsolearnedhowtohuntandfish.Whenhuntingfordeer,mytribehastworules：1)Nevershootafemaledeer,becauseshemightbepregnant,and2)Ifyoukilladeer,findawaytouseallofit.Goingtoc

B．veryboringC．closetonature D．justlikecitylife解析：選C推理判斷題。由第三段中的“there'sabigconnectiontotheland.Ourhouseissurroundedbyamountain...ourgarden”可推斷，作者生長(zhǎng)的地方的生活比較親近自然。11．ThetworulesmentionedinParagraph4are________.A．quiteeco-friendlyB．frequentlybrokenC．veryunreasonableD．difficulttounderstand解析：選A推理判斷題。由第四段中的“Nevershootafemaledeer,becauseshemightbepregnant”及“Ifyoukilladeer,findawaytouseallofit”可推斷，這兩條規(guī)定非常注重對(duì)生態(tài)環(huán)境的保護(hù)。故A項(xiàng)正確。12．Theunderlinedword“intimidating”inParagraph5canbestbereplacedby“________”．A．tiring B．a(chǎn)nnoyingC．interesting D．frightening解析：選D詞義猜測(cè)題。由倒數(shù)第二段中的“Goingtocollegehasbeenabigchangeforme”及下文提到的學(xué)校人數(shù)變得很多、身邊的土著人所占比例極小可推斷，這種與以往截然不同的生活對(duì)作者來(lái)說(shuō)有點(diǎn)“恐怖”但也很令人興奮。故畫(huà)線詞的意思應(yīng)是frightening。Ⅱ.閱讀七選五TheInternetcandosomuchmorethanjustbringingyourfavoriteshowtoyourbig-screenTV.It'smorethanjustaplacetopayyourelectricbills.__1__HerearefourwaystomaketheInternetworkforyourself-improvementandgrowth：?SearchingforinformationEnteranytopicofinterestintoyourfavoritesearchengineandimmediately,youwillhavealargeamountofinformationatyourfingertips.__2__Buthowtoknowwhethertheinformationyou'rereadingisbelievable—orcompletenonsense?Checkyoursources.Findoutwhopublishedtheinformation.Checkthepublisher'smotivation.?OnlineeducationandtrainingIfyou'vealwayswantedtofurtheryoureducationbuthaven'thadthetime,onlinecoursesmaybetheanswer.Unliketraditionalschools,Internet-basedlearningexcludestheneedforattendingclassesatthespecifictime.Askyourselfwhatyoureducationalgoalsare:Doyouwanttogetadegreeorcertificate,orjustexpandyourknowledge?__3__?Joinanin
