omotherinstitutionsliketheSalvadorDaliMuseuminSt.Petersburg，Florida.,试题：Whatdoestheword“contributions”inthelastparagraphreferto?A.Artworks.B.Projects.C.Donations.D.Documents.分析：画线单词contributions前出现了and，可利用同义或近义关系进行猜测。and前面提到了thefineselectionofthemajorworks(精选的重要作品)，后面说contributions来自其他机构，由并列关系可以推断出contributions应该属于works的范畴。故选A项。,5.根据反义，转折和对比关系进行猜测有些需要猜测词义的词或短语前后会出现表示转折或对比的词语，运用这些词语也可以帮助猜测词义。能体现转折、对比关系的词汇很多，常见的有but，yet，however，while，unlike，instead(of)，ontheotherhand，ratherthan，onthecontrary等。例如：Intheevening，ridesareusuallyatamorerelaxedandunhurriedpace，withgoldenlightstreamingacrossthegrassydeltaandtheanimalsingouttoeatanddrink.Sedatethoughtheyare，ridesatthistimeofdayarestillveryimpressive.,试题：Whatdoestheunderlinedword“sedate”probablymean?A.Wildandromantic.B.Slowandpeaceful.C.Hungryandthirsty.D.Activeandexcited.分析：画线词语所在句子的句意为“虽然它们，但是在一天的这个时候骑马观赏仍然令人印象非常深刻”。由though可知前后两句是转折关系，再结合前一句中提到的“atamorerelaxedandunhurriedpace”可知，应选B项，sedate意为“慢悠悠的，安静的”。,6.根据上下文进行猜测有些词义猜测题找不到以上标志线索，这时可以利用上下文提供的情景和线索进行合乎逻辑的综合分析，进而推测词义，这也是近几年来高考考查的热点。例如：(2016全国，C)Therearealsovarietiesdevelopedtosuitspecificlocalconditions.OneoftheverybestvarietiesforeatingqualityisOrleansReinette，butyoullneedawarm，shelteredplacewithperfectsoiltogrowit，soitsapipedreamformostappleloverswhofallforit.,试题：Whatdoestheunderlinedphrase“apipedream”inParagraph3mean?A.Apracticalidea.B.Avainhope.C.Abrilliantplan.D.Aselfishdesire.分析：由上文中的“OneoftheverybestvarietiesforeatingqualityisOrleansReinette，butyoullneedawarm，shelteredplacewithperfectsoiltogrowit.”可知，尽管OrleansReinette是很好的品种，但是对各项条件的要求很高，因此大多数喜欢它的人种植它的希望会落空。故选择B项。,随堂限时练,A(2018黑龙江齐齐哈尔一模)83-year-oldAntonioVicentehasspentthelastfourdecadesofhislifefightingagainstthetrend.AsBrazilianlandowners9cutdownrainforeststomakeroomfor1profitableplantations(种植园)andcattlegrounds，hestruggledtobringthejunglesofhischildhoodbacktolife.“WhenIwasachild，thepeasantscutdownthetreestomakegrasslandsandcharcoal，andthewaterdriedupanddidnoteback，”hetoldthereporters.“Ithought：Waterisvaluable，noonemakeswaterandthepopulationwillnotstopgrowing.Whatisgoingtohappen?Wearegoingtorunoutofwater.”,Withonlysomedonkeysandasmallteamofhiredworkers，AntonioVicentesetaboutbringingbacktheforesttohisland.Whatstartedoutasaweekendhobbysoonbecamea2permanentwayoflife，andAntoniorecallsoftenspendingwholedaysandnightsinhisyoungjungle，surroundedbyratsandfoxes，andeatingbananasandwichesforbreakfast，lunchanddinner.Overthelast40years，hehasplantedanestimated50,000treesonhis31-hectareland，whichnowmakeupasmallbutuniqueareaofrainforest，andahavenforwildlife.,Astheforestgrew，thewaterreturned，andAntoniosaysthattherearenowover20watersourcesonhislandthatwerenolongertherewhenheboughtit.Thentheanimalsstartedmakingahomethere.Today，theforestisalivewiththesoundsofbirdsand3insectslivingthere，andmorespeciesaresettlingineveryyear.“Therearetoucans(巨嘴鸟)，allkindsofbirds，squirrels，lizards，andeventheboarsarereturning，”83-year-oldVicentesays.“Ifyouaskmewhomyfamilyare，Iwouldsayallisrighthere，eachoneofthesethatIplantedfromaseed.”,语篇解读本文主要讲述一位83岁的老人用40年时间让热带雨林恢复生机的故事。,语篇解读,1.WhatdowelearnabouttheBrazilianpeasants?A.Theywastedmuchwateronfarming.B.Theyfocusedonshort-termprofits.C.Theycaredmuchabouttheenvironment.D.Theyreliedheavilyonrainforestsforaliving.,解析推理判断题。根据第一段中的“AsBrazilianlandownerscutdownrainforeststomakeroomforprofitableplantations.”及第二段中的“thewaterdriedupanddidnoteback”可知，巴西的农民关注的是短期的利益。故选B。,答案,解析,2.WhatusedtobeyoungAntoniosbiggestconcern?A.Overpopulation.B.Pollutedwater.C.Lossofgrasslands.D.Watershortage.,答案,解析,解析推理判断题。根据第二段中的“Waterisvaluable，noonemakeswaterandthepopulationwillnotstopgrowing.Whatisgoingtohappen?Wearegoingtorunoutofwater.”可知，年轻的Antonio最关心的是水的短缺。故选D。,3.Whatdoestheunderlinedword“haven”inParagraph3probablymean?A.Trap.B.Disaster.C.Shelter.D.Balance.,解析词义猜测题。根据第四段中的“insectslivingthere，andmorespeciesaresettlingineveryyear”可知，昆虫生活在这里，每年更多的物种在这里定居，由此可推断出这里成了野生生物的“安居地，避难所”。故选C。,答案,解析,4.Inthelastparagraph，Antoniomainlyexpresseshis.A.4affectionforhisforestB.thanksforhisfamilyC.deeploveforrarebirdsD.prideasasuccessfulfarmer,解析推理判断题。根据最后一段中的“Ifyouaskmewhomyfamilyare，Iwouldsayallisrighthere，eachoneofthesethatIplantedfromaseed.”可推知，Antonio主要在表达他对森林的爱。故选A。,答案,解析,B(2018广东茂名一模)Haveyoueverlostyourcaronaparkinglot?Ithappens.Youparkandgoshopping.Whenyougetback，youhavenoideawhereyourcaris.Itcanbediscouraging.Youdontneedtoinstall(安装)anexpensiveGPSsystemtokeep10trackofyourcar.Thatstooexpensive.Youwouldneedtopayamonthly5subscriptionfeejusttouseit.Butisthereawaytotrackyour6vehiclewithoutspendingafortune?Yes，nowthereis!ACalifornia-basedstart-uppanyisabletomakethisareality.,Theyhavecreatedatinydevice(装置)thatworkswithyoursmartphone，anditcanbeexactlywhatyourelookingfor!ItscalledTrackRBravo.Itschangingthewaywekeeptrackoftheimportantthingsinourlives.7InstallthefreeTrackRapponyoursmartphone，connecttheapptoyourdeviceandyourereadytogo!SimplyattachTrackRtowhateveryouwanttokeepaneyeon.Theentireprocessofsettingituponlytakes5minutesorless.Youcanattachittoyourkeys，walletandanythingelseyoudontwanttolose.Thenuset
