B．Anartist.C．Areporter。 D．Areader.答案：A推理判斷題。從第一段中可知,這位記者把他的簡歷和他寫的幾個報道送給了作者并跟作者說了他的許多心里話，這就很明確地表明這位記者想到作者的單位來工作，記者就是為編輯寫稿的,故選項A正確.此外，文章對象（主編）＋人稱代詞（our)，也可推斷出作者是一名主編。43．Theletteraimstoremindeditorsthattheyshould____.A．keeptheirbestreportersatallcostsB．givemorefreedomtotheirreportersC．beawareoftheirreportersprofessionaldevelopmentD．a(chǎn)ppreciatetheirreporters'workingstylesandattitudes答案：C推理判斷題。文章就是想提醒編輯們要了解記者們的職業(yè)需求和心理需求。最后一段第一句話是解題依據(jù).CLikedogs，sharksrelyonasharpsenseofsmelltotrackdownfood。Butnewresearchshowsnosesaren'ttheonlywaythatsharksdetectsmells：Theirentirebodies,infact,functionasgiantnosescapableofevenpickingupthe“shape"ofasmell。Runningdownthesidesofeverysharkarenerve.packedstripscalledsidelines。Researchersknowthesesensitivestructurescandetectthefaintmovementssentbylivingthingsinwater,buttheirabilitytopickupthesmellwaspreviouslyunknown.Evenmoresurprising，researcherssaid，isthatsidelinescandetectthe3—D“plumes”ofsmells-structureslookingliketurbulenceleftbehindafterwavingahandthroughthickfogorsteam.“Odorplumesarecomplex，dynamic，three。dimensionalstructuresusedbymanyanimalspeciestolocatefood，matesandhomesites，”saidJelleAtema,aBostonUniversitybiologistandco.authorofthestudydetailedinanupcomingissueoftheJournalofExperimentalBiology.Whenpreventedfromusing“odorplumes”information,thestudyshows，sharksareunabletofindthesourceofanodor。Tofindthisout,researchersdidanexperiment.Theyranastreamofsquid(魷魚）odorthroughacirculatingwatertankandnotedashark'sabilitytofindthesource—withnoeddies(漩渦)andplumestotrack,thesharkalmostalwaysfailed.Theythenusedthesamesetup，butaddedabrickbehindthesmellsource,therebymixingtheflowofthesquid'ssmellandgivingthesharkmoreinformationtotrackit.Sureenough,thesharkgotonmuchbetterinlocatingthe“prey"．Researchersalsonumbed(麻醉)thelaterallineswithacommonantibiotic,producingasimilarlydisablingeffectonthesharks'huntingabilities.“Theresultsareinterestingforourunderstandingofanimals’navigationunderwaterandforthedevelopmentofguidanceofautonomousunderwatervehicles，”Atemasaid.44．Whatwasthepurposeoftheexperiment?A．Theywantedtoprovesharksaregoodatlocatingtheprey。B．Theywantedtoprovesharksareunabletofindthesourceofanodorwithoutusing“odorplumes”information。C．Theywantedtoprovesharkshaveabetternavigationabilityunderwater.D．Theywantedtoprovesharkscandetectthefaintmovementssentbylivingthingsinwater.答案：B細(xì)節(jié)理解題.根據(jù)第三段最后一句話“Whenpreventedfromusing“odorplumes"information，thestudyshows，sharksareunabletofindthesourceofanodor。"和第四段第一句“Tofindthisout，researchersdidanexperiment."可知實驗的目的是為了證明沒有味狀信息，鯊魚無法找到氣味的來源。45．Whatpartofbodydodogsdependontotrackdownfood?A．Mouths. B．Eyes.C．Tails. D．Noses.答案：D推理判斷題。根據(jù)第一段第一句“Likedogs,sharksrelyonasharpsenseofsmelltotrackdownfood."可知，狗和鯊魚一樣都是通過嗅覺來覓食的。46．Intheexperiment,whywasabrickaddedbehindthesmellsource？A．Togivethesharkmoretimetotrackit.B．Togivethesharklessinformationtotrackit.C．Toconfusethesharkwithtoomanydifferentodors.D．Togivethesharkmoreinformationtotrackit。答案：D細(xì)節(jié)理解題。根據(jù)第四段第三句“Theythenusedthesamesetup，butaddedabrickbehindthesmellsource，therebymixingtheflowofthesquid'ssmellandgivingthesharkmoreinformationtotrackit。”可知，放一塊磚頭的目的是為了把魷魚的氣味混合到水流中去，這樣可以為鯊魚尋找目標(biāo)提供更多的信息.47．Whichisthemainideaofthepassage？A．Sharksusenosestohuntfood.B．Howdoanimalsnavigateinwater?C．Sharksuse“odorplumes”tohuntfood。D．Odorplumesareveryusefulforanimalstolocatefood,matesandhomesites.答案：C主旨大意題。綜觀全文可知，本文主要介紹的是鯊魚通過感知“味狀”來確定獵物的位置這一情況。D(2010浙江卷）MyfamilyandIlivedacrossthestreetfromSouthwayLookingback，Ithinkwhatsentencedtheparktooblivion(被遺忘）wasthedrought(旱災(zāi))wehadaboutfouryearsago。Upuntilthen，SouthwayTherehadbeenalmostnorainatallthatyear.Thecitystoppedwateringtheparkgrass。WithinafewweeksIfoundmyselflivingacrossthestreetfromahugebrowndesert。Leavesfellofftheparktrees，andprettysoonthetreesstarteddying,too。Next,theparkswimmingpoolwasclosed.Thecitycutdownontheworkforcethatkeptthepark，andprettysoonitjustgottoouglyanddirtytoenjoyanymore。Asthedroughtlastedintothefall,theparkgotworseeverymonth。Therubbishpileduporblewacrossthebrowngrass.Soontheonlypeopleintheparkwerebeggarsandotherpeopledownontheirluck。Peoplesaiddrugswerebeingsoldortradedtherenow.Theparkhadgottenscary，andmymothertolduskidsnottogothereanymore。Thedroughtfinallyendedandthingsseemedtogetbacktonormal，thatis，everythingbutthepark。Ithadgottenintosuchbadshapethatthecityjustletitstaythatway.ThenaboutsixmonthsagoIheardthatthecitywasgoingto“redevelop”certainworn。outareasofthecity.Itturnedoutthatthecityhadplannedtogetridofthepark，sellthelandandletsomeonebuildrowsofapartmentbuildingsonit.Thechain.linkfencingandthebulldozersdidtheirwork。Nowweliveacrossthestreetfromsixrowsofapartmentbuildings.Eachofthemisthreeunitshighandstretchesablockineachdirection.Theneighborhoodhaschangedwithoutthepark。ThestreetsIusedtoplayinarejammedwithcarsnow.Thingswillneverbethesameagain.Sometimes_I_wonder，_though，_what_changes_another_drought_would_make_in_the_way_things_are_today.48．Howdidthewriterfeelwhenhesawthefenceandbulldozers?A．Scared. B．Confused.C．upset。 D．Curious。答案:C推理判斷題。作者從小到大一直非常喜歡街對面的公園，而現(xiàn)在公園被柵欄圍了起來，公園內(nèi)的樹木和花草遭到破壞，作者感到失望和沮喪。49．Whywasthewritertoldnottogototheparkbyhismother?A．Itwasbeingrebuilt。B．Itwasdangerous.C．Itbecamecrowded.D．Ithadturnedintoadesert.答案：B細(xì)節(jié)理解題。由第四段的最后一句“Theparkhadgottenscary，.。。”可知公園被廢棄了，里面住著流浪漢,甚至還有人在此販毒，所以母親叮囑“我們”不要去那兒，因為那兒很危險了。50．Accordingtothewriter，whateventuallybroughtaboutthedisappearanceofthepark？A．Thedrought.B．Thecrime。C．Thebeggarsandtherubbish.D．Thedecisionsofthecity.答案：D推理判斷題.由全文可知,干旱使得公園成為了被遺忘的角落,但真正使公園消失的原因是城市重新規(guī)劃這塊廢棄土地的決定。51．Thelastsentenceofthepassageimpliesthatifanotherdroughtcame，________.A．thesituationwouldbemuchworseB．peoplewouldhavetodeserttheirhomesC．thecitywouldbefullypreparedinadvanceD．thecitywouldhavetoredeveloptheneighborhood答案：A句意猜測題。四年前的一次干旱使得美麗的公園消失得無影無蹤，那么下次干旱會使我們現(xiàn)在的生活發(fā)生什么改變呢？作者在最后一段描述了目前所居住的街道的變化—-變得更加擁擠，從而引出了上述的思考.結(jié)論不言而喻-—環(huán)境會變得更加糟糕。EPlantsareabletomaketheirownfood。Afewplantsalsocatchfood.Theirleavesactastraps。Theycatchinsects。Thesundewisonesuchplant.Ithasakindofjuice,ornectaronitsleaves。Thenectarissweetandsticky。Itsodorattractsinsects.Theylandontheleaves.Theygetstuck.Oftentheytrytopullaway。Theyfighttogetfree。Butstrugglingdoesnothelptheinsect.Theharderitpulls,themoreitgetsstuck。Soonshorthairsontheleafbegintobend。Theyfoldovertheinsect.Thenlongerandlongerhairsdoso.Allthehairsmove.Theyfoldover，pinningtheinsectdown。Itmaytakeafewminutesforthistohappen.Itmaytakehours.Thetimevaries.Itdependsonhowslowlytheplantacts。Itdependsonhowmuchtheinsectfight。Aboutaweeklater,thehairsunfold。Theinsecthasbeeneaten.Theplantisreadyforitsnextvictim.Butitwillhavefewsuchmeals。Itwilleatonlythreeorfourinsects.Thenitwilldie。Thesundewplanttrapsinsectsratherslowly。Thisisnottrueforsomeotherplants.Theyaremuchfaster.TheVenusflytrapisoneofthese.Itclosesinhalfasecondforless.Ithassixtinyhairsoneachleaf.Theleafsnapsshutwheninsectstouchthehairs。Theinsectsarecaughtinside。Atfirst,spacesremainwheretheleafedgesmeet.Theinsectsmaytrytosqueezeoutthroughtheopenings。Someinsectswillgetthrough.Theywillescape。Soon,though,thesidesoftheleafdrawtightlytogether.Thenthereisnowayout.Youcanseethisplantworkbyputtingsomethingontheleaftotouchthehairs.Youmustwatchitcarefully,though.Theleafwillsnapshutsoquicklythatyouwillmissitifyouglanceaway.52．Thesundew________.A．isakindofplantwhichlivesoninsectsB．hasbothshorthairsandlonghairsonitsleavesC．lookslessattractivethantheVenusflytrapD．caneatonlyfourinsectsatmosteachtime答案：B依據(jù):①Soonshorthairsontheleafbegintobend.②Thenlongerandlongerhairsdoso.可知sundew這種植物的葉子上既有短茸毛也有長茸毛.A項“這種植物靠昆蟲為生”與原文“能捕捉昆蟲的植物"概念并不完全一樣；C、D兩項文中并未提及。53．Allthefollowingcanhelpthesundewtocatchinsectsexceptits________。A．leaves B．smellC．hairs D．colour答案:D依據(jù)：①Theirleavesactastraps。②Itsodorattractsinsects.③Soonshorthairsontheleafbegintobend.Theyfoldovertheinsect。Thenlongerandlongerhairsdoso。文中并沒有提到顏色。odor“氣味"，相當(dāng)于smell。A、B、C三項文中都有相對應(yīng)的信息.54．Theinsectmayescapebeingeatenifit________。A．fightsagainsttheplantashardasitcanB．triestofleethroughtheopeningsassoonaspossibleC．doesitsbesttopulltheleafopeninlimitedtimeD．remainsstillforsometimeandthentriestofindachancetoflyout答案：B依據(jù):①Theinsectsmaytrytosqueezeoutthroughtheopenings.②Someinsectswillgetthrough可知，如果昆蟲在葉子完全合攏前盡力從縫隙中擠出,還會有一線生機。C項“在有限的時間內(nèi)把葉子拉開”，A項“與這種植物斗爭”與原文信息不符。原文說昆蟲是趁著葉子還沒有完全合攏的時候逃脫，而D項“先靜止不動再找機會逃脫”也不符合文意。55．Whichofthefollowingstatementsistrueaccordingtothetext？A．TheVenusflytrapcanshutaflyinitsleafinlessthanasecond。B．Thesundewwilldiesoonafterithaseatentheinsect.C．Ittakesmorethanaweekforthesundewtotrapaninsect。D．It’salittledangeroustoputsomethingtoseehowtheplantworks.答案：A依據(jù)第四段第四句話：Itclosesinhalfasecondorless。inhalfasecond半秒鐘內(nèi)；orless或者更少。本句說明樹葉合攏的速度非?？?。Ⅳ。書面表達(dá)（滿分25分)（遼寧省沈陽市2010年高三年級教學(xué)質(zhì)量檢測二）目前，隨著環(huán)保意識的增強,越來越多的人們開始倡導(dǎo)低碳生活.請根據(jù)下面的圖表以及中文提示,用英語寫一篇短文，簡要描述全球近五十年來的氣候變化，并分析其產(chǎn)生的主要原因、影響及解決措施。原因1)過多使用礦物燃料；2）過度砍伐森林.影響1)海平面上升；2）極端天氣現(xiàn)象增加；3）自然平衡被破壞。措施1)控制二氧化碳排放;2）采用新型能源注意：1.短文必須包括以上圖表所表現(xiàn)的主要內(nèi)容。2．短文單詞數(shù):100左右(開頭已給出的單詞不計入單詞總數(shù))。3．參考詞匯：礦物燃料fossilfuels；二氧化碳carbondioxide;
