B．Byreference.C．Byaccident. D．Bycomparison.解析：選C推理判斷題。根據(jù)第四段的內(nèi)容可推知，她是通過一次小意外發(fā)現(xiàn)了短吻鱷臉上小黑點的作用。故選C。4．Whatcanbeinferredfromthelastparagraph?A．Cavefishlosesightastheygrowup.B．DaphneSoaresdevotesherenergytoresearchwork.C．Alligators'genesarethesameascrocodilians'.D．DaphneSoaresdiscoveredanewspeciesofalligator.解析：選B推理判斷題。根據(jù)最后一段內(nèi)容可知，達(dá)芙妮·索雷斯除了研究短吻鱷，還在研究洞穴魚，并對鱷目動物進(jìn)行更多的研究工作，由此可推知，達(dá)芙妮·索雷斯把自己的精力投入到研究工作中。故選B。BAnunderwaterrobotnamedIcefinhasgonetothebottomofAntarctica'sThwaitesGlacier(冰川)recently,whichisoneofAntarctica'sfastestmelting(融化)glaciers.Evenso,scientistslearnedunexpectedlythatwatersatthegroundline,theregionwheretheglaciermeetsthesea,aremorethan2degreesCelsiusabovethenormalfreezingtemperature.Thejourneytocollectthedatawasn'teasy.ScientistsdroppedIcefinthrougha700-meter-deepholetheyhaddrilledthroughtheglacier.“We'reproudofIcefin,sinceitrepresentsanewwayoflookingatglaciers，”saidBritneySchmidt,leadscientistforIcefin.“Forreallythefirsttime,wecandrivemilesundertheicetomeasureandmapprocesseswecan'totherwisereach.We'vetakenthefirstclose-uplookatagroundingzone.It'sour‘walkingonthemoon’moment.”Thegroundingzoneistheregionwherethebottomoftheglaciermeetstheseawaterbeneathit.Theteamspentthelasttwomonthsinminus30℃ThwaitesGlacier,roughlythesizeofFlorida,whichpreventstheicebehinditfromfreelyflowingintotheocean,ismeltingatanincreasinglyfastrate.Itsmeltingalreadyaccountsforabout4%oftheglobalsearise,GeorgiaTechreported.TheamountoficeflowingoutofThwaitesintotheseahasdoubledinthepast30years,greatlychangingthelandscape,temperaturesandtheecosystemofAntarctica.“WeknowthatwarmeroceanwatersareerodingmanyofWestAntarctica'sglaciers,butwe'reparticularlyconcernedaboutThwaites，”KeithNicholls,anoceanographerwiththeBritishAntarcticSurveyandtheUnitedKingdomleadontheteam,saidintheGeorgiaTechstatement.“Thisnewdatawillprovideanewviewpointoftheprocessestakingplace,sowecanpredictfuturechangewithmorecertainty.”語篇解讀：本文是一篇說明文?？茖W(xué)家把一臺水下機(jī)器人放入思韋茨冰川底部進(jìn)行科學(xué)考察，發(fā)現(xiàn)那里的水溫高于一般的結(jié)冰溫度。5．WhatwerescientistssurprisedtodiscoveratthebottomofThwaitesGlacier?A．Ameltingglacier. B．Warmwaters.C．Thegroundline. D．Anunderwaterrobot.解析：選B細(xì)節(jié)理解題。根據(jù)第一段第二句可知，出乎科學(xué)家們意料的是他們發(fā)現(xiàn)在這個冰川底部水溫竟然高于一般的結(jié)冰溫度2攝氏度。最后一段中的“WeknowthatwarmeroceanwatersareerodingmanyofWestAntarctica'sglaciers”也是提示。6．WhatdidIcefindoasitmovedalongunderwater?A．Ittookphotos. B．Itmappedthearea.C．Itdrilledholes. D．Itmeasuredseawater.解析：選A細(xì)節(jié)理解題。根據(jù)第三段中的“Asitmovedalong,Icefintookmeasurementsandrecordedwhatitsawwithaninsidecamera”可知，當(dāng)機(jī)器人在水底向前移動的時候，它同時還測量海水和用內(nèi)置照相機(jī)記錄情況。7．FromParagraph4,wecaninferThwaitesGlacier________.A．isextremelyvitaltoAntarcticaB．isalotlargerthanFlorida,USAC．ismeltingthefastestinAntarcticaD．istoblamefortheglobalseariseentirely解析：選A推理判斷題。根據(jù)第四段中的“preventstheicebehinditfromfreelyflowingintotheocean”及“greatlychangingthelandscape,temperaturesandtheecosystemofAntarctica”可推知，思韋茨冰川對南極至關(guān)重要。8．Whatdoestheunderlinedword“eroding”inthelastparagraphmean?A．Accumulating. B．Shaping.C．Raising. D．Destroying.解析：選D詞義猜測題。根據(jù)畫線詞后的“butwe'reparticularlyconcernedaboutThwaites”可知，畫線詞應(yīng)表示一種令人擔(dān)憂的情況；再結(jié)合前面的“warmeroceanwaters”和畫線詞后面的動作承受者“manyofWestAntarctica'sglaciers”可推知，畫線詞表示“侵蝕”，故選D。Ⅱ.應(yīng)用文寫作假定你是李華，你校英文報“外國文化”欄目擬刊登介紹外國節(jié)日風(fēng)俗和中學(xué)生生活的短文。請給英國朋友彼得寫信約稿，要點如下：1．欄目介紹；2．稿件內(nèi)容；3．稿件長度：約400詞；4．交稿日期：6月28日前。注意：1.詞數(shù)80左右；2．可以適當(dāng)增加細(xì)節(jié)，以使行文連貫；3．開頭和結(jié)尾已為你寫好，不計入總詞數(shù)。DearPeter，I'dliketoaskyoutowriteanarticleforourschool'sEnglishnewspaper.I'mlookingforwardtohearingfromyou.Yours,LiHua參考范文：DearPeter，I'dliketoaskyoutowriteanarticleforourschool'sEnglishnewspaper.The“ForeignCultures”sectioninournewspaperisverypopularamongusstudents.Itcarriesarticleswrittenbyforeignfriendsabouttheculturesoftheirhomecountries.Wouldyoupleasewritesomethingaboutthecultureinyourhometown?AndwewouldespeciallywelcomearticlesabouthowtheBritishspendtheirholidaysandfestivals,andthelifeofBritishhighschoolstudents.Youcanwriteanythingrelevantsolongasit'sinterestingandinformative.400wordswouldbefine.CouldwehaveyourarticlebeforeJune28?I'mlookingforwardtohearingfromyou.Yours,LiHua課時作業(yè)(二)一、主題語基拓展練(一)主題詞匯盤查(已會詞匯，在□內(nèi)打“√”；欠熟練詞匯，多翻閱識記)①wetland

B．difficultC．personal D．long解析：選B推理判斷題。根據(jù)第二段Greene對這個問題的解釋以及他說需要未來的物理學(xué)家去解決可知，作者提出的這個問題非常難。2．ThebooksbyWeinbergandSusskind________.A．a(chǎn)reboringtoreadB．a(chǎn)remainlyaboutmathC．a(chǎn)repopularsciencebooksD．a(chǎn)reonlypopularamongkids解析：選C推理判斷題。根據(jù)第三段中的“booksby...‘makeitagreattimeforpeoplewhowanttolearnaboutbigideasbutaren'tyetready,perhaps,tolearnmath’”可知，Greene認(rèn)為Weinberg和Susskind等物理學(xué)家寫的書淺顯易懂，適合普通大眾閱讀，故這些書屬于科普讀物。3．AccordingtoParagraph4,whichofthefollowingdoesGreeneagreewith?A．Modernphysicsisaboringsubject.B．Interestplaysanimportantroleinstudying.C．Itisnotnecessarytolearnallaboutphysics.D．ItiseasytodescribeblackholesandtheBigBang.解析：選B推理判斷題。根據(jù)第四段他所說的話可知，他認(rèn)為興趣在學(xué)習(xí)過程中起著非常重要的作用。4．Inthelastparagraph,Greenehopesthat________.A．kidscanlovescienceandphysicsB．kidscandowellinphysicsexamsC．kidscanhavefunwithexperimentsD．kidscanfindmorestrangethingsinlife解析：選A推理判斷題。根據(jù)最后一段的“GreenehasfollowedAlbertEinstein'sleadintryingtosolvethemysteriesoftheuniverse.Nowhewantskidstodothesame.”可知，Greene希望孩子們可以像他一樣對科學(xué)和物理感興趣，去探索宇宙的奧秘。Ⅱ.閱讀七選五Itseemsthattheissueoverbatsisonewheremanyhumansaredivided.__1__Butthosethatknowaboutthebatsinmoredetailaretheonesthatfindthemtobefascinatingcreatures.Rabies(狂犬病)isoftenthoughttobecarriedbydogs.However,batscarryittooandmorepeopleareinfectedbythemannuallythanbydogs.Abatcanbiteahumanastheysleepandthepersonmaynotevenfeelit.__2__Careshouldbetakenabouthowareaswherebatswerelivingarecleaned.Infact,itisbesttoallowaprofessionaltocleanupthewastethathasbeenleftbehind.__3__Itcanalsoresultindustfromoldwastereleasingharmfulpiecesthatcangetbreathedin.__4__Forexample,insomeareasfarmerspayforthebatcavestobeminedforfertilizer(肥料).Batsalsokeepourenvironmentfreefromvariousinsects.Couldyouimaginehowmanyofthemwouldbearoundifthereweren'tthousandsofbatsouteverysinglenightconsumingthem?Itcouldquicklybeanightmarethatgetsoutofcontrol.Humansmustfindawaytobeinbalancewithbats.Batsmakeuponefifthoftheworld'smammals.Thatisquitesomething.__5__A．Itisveryimportantforustofindaproperplacetosleep.B．Othersarefondofthecreatureswithsharpteethflyinginthesky.C．Manypeopleareafraidofthemduetowhattheyhaveheardaboutthem.D．Inadequatecleaningcanleadtoserioushealthproblemsforfamilymembers.E．Therearesomepositiveelementsofhumansandbatsthathavebeenrecorded.F．Therefore,childrenareespeciallyaconcernwhenitcomestorabiesfrombats.G．Identifyinglocationswherethesecreaturescanlivepeacefullyispartofthatbalance.語篇解讀：本文是一篇說明文。文章介紹了一些有關(guān)蝙蝠的知識。1．解析：選C根據(jù)上文中提到的人們對蝙蝠看法各異可知，后面兩句應(yīng)分別說出兩種截然不同的觀點，故C項“許多人因為聽說的有關(guān)蝙蝠的信息而害怕它們”承上啟下，符合語境。2．解析：選F空前講蝙蝠會在人們睡覺時咬人，被咬的人甚至可能感覺不到，F(xiàn)項“因此，當(dāng)說到來自蝙蝠的狂犬病時，兒童尤其令人擔(dān)憂”與前文內(nèi)容構(gòu)成因果關(guān)系，符合語境。3．解析：選D此段是關(guān)于清理蝙蝠糞便和蝙蝠糞便的危害。根據(jù)空后的“Itcanalsoresultin”可知，前后兩句話之間為遞進(jìn)關(guān)系，故選D項“清潔不足會給家庭成員帶來嚴(yán)重的健康問題”，空后的It指代選項中的“Inadequatecleaning”。4．解析：選E根據(jù)段落結(jié)構(gòu)和空后所舉例子可知，空處為本段主旨句，此段介紹了有關(guān)蝙蝠對人類有利的方面。5．解析：選G此段講到人類須找到一種方式與蝙蝠和諧、平衡相處，G項中的“thatbalance”與上文的“inbalancewithbats”相呼應(yīng)，故選G。Ⅲ.語法填空ThePrzewalski'shorse(蒙古野馬)isarareandendangeredwildhorse.Only12indi
