B．Current.C．Fundamental. D．Temporary.解析：詞義揣測題。第四段該句中，while表示對比，ephemeral與lastedforweeksorevenmonths“長久的”意義相反，是“短暫的”；B項意為“現(xiàn)在的、目前的”，與“過去的(past)”和“將來的(future)”意義相對，所以不對。A、C則與while后文意義不能形成對比。答案：D2．Whyistheiceinthecenteroficeringsfrozenwhilethatattheedgeismelted?A．Becausethecenteroficeringsis2to4warmerthantheedge.B．Becausethecurrentsinthecenterarelesspowerful.C．Becauseitistoowidetoberecognizedorincited.D．Becausewaterinthecentercirculatesinaclockwisedirection.解析：細微環(huán)節(jié)理解題。考查因果關系。從其次段第三句“Intheeddycenter，theicedoesnotmelt—eventhoughthewateriswarm—becausethecurrentsareweak”可知B項正確，因為暖流不夠急促，所以造成只有冰的邊緣才能溶解的現(xiàn)象；A項偷換概念，從第三段最終一句可知漩渦水溫高于周邊水溫，不是冰環(huán)中心與邊緣溫差的比較，更不是題干緣由；C項同樣表述有誤，從第四段第一句可知其講解并描述的是mostoftherings，不是theiceinthecenteroficerings，而且答非所問；D項表述不精確，從其次段其次句可知，waterinthecenter應改為warmeddies，并且不是冰環(huán)中心保持凍結的緣由。答案：B3．WhichofthefollowingstatementsaboutLakeA．Theyarecausedbyhotandcircularcurrentsundertheice.B．TheiceinthecenterofLakeC．Researchersareuncertainabouttheexactreasonoftheeddies'existence.D．Lake解析：細微環(huán)節(jié)理解題。從文章最終一段可知C項正確。從最終一段第一句“ResearchersarestillinvestigatingwhatcausesBaikal'seddies...”可知Baikal'seddies的成因尚不明確，故A項錯誤，依據(jù)第一段其次句，A項可改為“theringsarecausedbywarm，circularcurrents...”；依據(jù)其次段第一句可知B項表述錯誤；依據(jù)第三段“Kouraevandhiscolleagues...setsensorscapableofmeasuringthetemperatureandsalinityofthewatertoadepthof700feet”可知D項偷換概念。答案：C4．Whatmaybethebesttitleforthepassage?A．What'sCausingtheGiantIceRingsinSiberia?B．TheMysteryoftheEddiesintheLakeC．TheLargestandDeepestFreshwaterLake—LakeD．WhyDoestheEdgeofanIceRingMeltFaster?解析：標題歸納題。此文主要介紹了西伯利亞貝加爾湖多年的冰環(huán)之謎的答案在于冰面下方的暖流漩渦，所以選A。解答漩渦之謎，并非本文重點，只在最終提及而已，B項表述有誤；C項的范圍太大；D項范圍縮小，不足以概括文章。答案：AB(2024·河南九師聯(lián)盟5月聯(lián)考)Ithasbecomeahabitformanyofus.Whenyou'retiredofonlineshopping，youheadtothebathroomtodoyourbestmake-upfortheperfectselfies(自拍)forFacebook，Instagram，Snapchatoralloftheabove.Whenyou'reready，youholdupyourphoneand，inaninstant，snap(拍照)．Buthaveyoueverwonderedwhat'sbehindyourburningdesiretoself-document？Mostpeoplewouldsaythatthisisawaytoexpressthemselvesandperhapsmakethembecomemoreconfidentofthemselves.Butthemomentyouuploadthatpicture，it'snolongeryourstojudge.Instead，youpassonthatpowertotheonlineworld.Whileyoumaythinkthatyourgrowingcollectionofselfiesattractspeople，quitetheoppositemaybetrue.Arecentstudywasconductedonatotalof238peopleinAustria，GermanyandSwitzerland.77%ofthepeoplesurveyedadmittedtoregularlytakingselfies.Interestingly，82%ofpeoplesaidthattheywouldratherseefewerselfiesonsocialmedia.Inotherwords，weliketakingselfiesbutseriouslydislikelookingatotherpeople'sselfiesonline.Thisresearchfindsthatthereisabigdifferencebetweenhowweseeourownselfiesandhowwejudgeotherpeople'spictures.Itsuggeststhatwearecomfortablewiththeselfieswepostsincewebelievetheyareobviouslynotseriousorvain，butwethinkeveryoneelseisanegoist(自我主義者)fordoingtheverysamething.Afterall，weareabletoseparateourownselfiesfromtheseaofthemonlineandnaturallythinkthatoursaretheonlyauthenticones.So，thenexttimeyoureachforyourphoneandtakeaselfiepicture，considerthis:Thepeoplearoundyoumaynotneedanothercarefullyplannedsnapofyourface.Instead，youmightbebetteroff，givingitabreakandcallingofftheselfiephototoday.Whileyou'reatit，makesureyouneverpostthesepicturesonsocialmediaeither.[語篇解讀]本文是一篇說明文?，F(xiàn)在我們都喜愛自拍，然后發(fā)到社交網(wǎng)站上，并且我們認為自己的自拍照會吸引別人。一項探討發(fā)覺，我們喜愛在社交網(wǎng)站看自己的自拍照，卻不喜愛看別人的自拍照，并且認為他人的自拍照不真實。這個好玩的結論告知我們，即使我們喜愛自拍，也不要隨意將自拍照放到網(wǎng)上。5．Whatismostpeople'sideaontakingtheirownselfiesaccordingtothetext?A．It'sagoodwaytokeepothersinformedoftheirlife.B．Itcostslessmoneythanshoppingonlineformake-up.C．It'sawayofself-expressionandbuildingconfidence.D．Itcanhelpthemkeeparecordoftheirdailyroutines.解析：細微環(huán)節(jié)理解題。依據(jù)其次段“Buthaveyoueverwonderedwhat'sbehindyourburningdesiretoself-document？Mostpeoplewouldsaythatthisisawaytoexpressthemselvesandperhapsmakethembecomemoreconfidentofthemselves.”可知，大部分人認為拍自拍照是一種表達自我和建立自信的方式。答案：C6．Howdootherpeoplefeelaboutouronlineselfiesthatweconsiderattractive?A．Theyactuallytakegreatinterestinthem.B．Theyenvyourlifeafterappreciatingthem.C．Theyarelikelyunwillingtoseethemonline.D．Theyhardlymakeannoyingreviewsonthem.解析：推理推斷題。依據(jù)第三段“Whileyoumaythinkthatyourgrowingcollectionofselfiesattractspeople，quitetheoppositemaybetrue.”及“Interestingly，82%ofpeoplesaidthattheywouldratherseefewerselfiesonsocialmedia.Inotherwords，weliketakingselfiesbutseriouslydislikelookingatotherpeople'sselfiesonline.”可推斷，別人可能不情愿在網(wǎng)上看到我們自認為具有吸引力的自拍照。答案：C7．
