课前预习自测一份令人兴奋的工作我的工作是世界上最伟大的工作。我跑的地方是稀罕奇特的地方，和我一道工作的人来自世界各地。(我们)有时在室外工作，有时在办公室里，有时工作中要用科学仪器，有时要会见当地百姓和旅游人士，但是我从来不感到工作烦人。虽然我的工作偶尔也有危险，但是我并不在乎，因为危险能激励我，使我感到有活力。然而，最重要的是，通过我的工作能保护普通百姓免遭火山的威胁——这是世界上最大的自然威力之一。作为一名火山学家，二十年前我被派到夏威夷火山观测站工作。我的任务是收集有关基拉韦厄火山的数据资料，这是夏威夷最活跃的火山之一。收集和评估了这些信息之后，我就帮助其他科学家一起预测下次火山熔岩将往何处流去，流速是多少。我们的工作拯救了许多人的生命，因为在熔岩要流经之地，老百姓都可以得到离开家园的通知。遗憾的是，我们不能把他们的家搬离岩浆流过的地方，因此，许多房屋被熔岩淹没，或者焚烧殆尽。当滚烫的岩石从火山喷发出来并撒落回地面时，它所造成的损失比想象的要小一些。这是因为在岩石下落的基拉韦厄火山顶附近无人居住。而像波浪一样顺着山坡慢慢下流的火山熔岩所造成的损失却大得多，这是因为火山岩浆所流经的地方，一切东西都被掩埋在熔岩下面了。然而，火山喷发本身的确是很壮观的，我永远也忘不了第一次看见火山喷发时的情景。那是在我抵达夏威夷后的第二个星期。那天我辛辛苦苦地工作了一整天，很早就上床睡觉了。我在熟睡中突然感到床铺在摇晃，接着我听到一阵奇怪的声音，就好像一列火车在我的窗外行驶一样。因为我在夏威夷曾经经历过多次地震，所以对这种声音我并不在意。我刚要再睡，突然我的卧室亮如白昼。我赶紧跑出房间，来到后花园，在那儿我能远远地看见基拉韦厄火山。在山的一边有火山喷发，红色发烫的岩浆像喷泉一样，朝天上喷射达几百米高。真是绝妙的奇景！就在这次火山喷发的第二天，我有幸作了一次近距离的观察。我和另外两位科学家驱车上山，到最靠近这次火山喷口的地方才下车。早先从观测站出发时就带了一些特别的安全服，于是我们穿上安全服再走近火山口。我们三个人看上去就像宇航员一样。我们都穿着白色的防护服遮住全身，戴上了头盔和特别的手套，还穿了一双大靴子。穿着这些衣服走起路来实在不容易，但我们还是缓缓往火山口的边缘走去，并且向下看到了红红的沸腾的中央。另外两人攀下火山口去收集供日后研究用的岩浆，我是第一次经历这样的事，所以留在山顶上观察他们。如今，我和当初从事这项工作时一样满怀热情。虽然我从事火山研究很多年了，但是我对火山的壮丽景色以及它那潜在的巨大破坏力至今仍然感到惊愕不已。课堂合作探究Inyourgroupsdiscusswayshumanbeingsprotectthemselvesfrompowerfulnaturalforces.(教材P33)在你们组内讨论一下人类保护自己免受自然威力伤害的办法。protect...from...保护……免受……①Theyhuddledtogetherto__________themselves________thewind.他们挤在一起，免受风吹。②Measuresmustbetakento________therarebirds________beingendangered.必须采取措施保护稀有鸟类，使其免遭灭绝。protectfromprotectfrom名师点津与“protect...from...”结构相似的短语：preventsb./sth.(from)doing(用于被动语态时from不可省略)stopsb./sth.(from)doing(用于被动语态时from不可省略)keepsb./sth.fromdoing(from不可省略)【即景活用】单句语法填空①Troopshavebeensenttoprotectaidworkers________attack.②Heaskedtobeputunderpolice________(protect)．答案：①against/from②protection答案课文预学检测Ⅰ.Fast­readingReadthetextquicklyandthentrytowritedownthemainidea.Thepassagemainlytellsusa________excitingjobandhisfirstsightofan________.答案：volcanologist's;eruption答案Ⅱ.Careful­readingChoosethebestanswersaccordingtothepassage.1．Thewriterdoesn'tmindtheoccasionaldangerofhisjobbecause________.A．hetravelstounusualplacesandmeetsinterestingpeoplefromallovertheworldB．helikesthedifferentwaysofworkingC．hethinkshisjobthemostimportantD．heisexcitedaboutdangersandfeelsalive答案：D答案2．Whydoesthelavathatflowsslowlydownthemountaincausefarmoredamagethantheboilingrockthateruptsfromthevolcano?A．Becauseitburieseverythinginitspath.B．BecausemostpeoplelivenearthetopofMountKilauea.C．Becausethelavaisinahighertemperature.D．Becausethevolcanologistscannotpredictit.答案：A答案3．WhichofthefollowingisTRUEaccordingtothepassage?A．Theboilingrockwhicheruptsfromthevolcanoandcrashesbacktoearthcausesmoredamagethanthelava.B．Thelavathatflowsslowlydownthemountaincausesfarmoredamagethantheboilingrock.C．Theeruptionisnotexcitingtowatch.D．Theauthorclimbeddownintothecratertocollectinformationaftertheeruption.答案：B答案4．Whydidthevolcanologistrunoutofthehouseintothebackgarden?A．Becausehisbedbeganshaking.B．Becausehisbedroomsuddenlybecameasbrightasday.C．BecausehethoughttherewasanearthquakeinHawaii.D．Becausehewantedtocollectinformationabouttheeruption.答案：B答案5．Whatdidtheauthordoafterhewasappointedasavolcanologist?A．HecollectedinformationaboutMountKilaueaonthespot.B．Heanalyzedthedataandpredictedwherethelavawouldflow.C．Hepersuadedpeopletomovetheirhomesoutofthepathofthelava.D．Hesavedpeoplewhowerecoveredwithlava.答案：A答案课后演练提能[基础题]Ⅰ.单词拼写1．Don'tworry.Yourvoicesounds________(绝对地)fine.答案：absolutely答案2．Macwaspedalinghardnow.He________(挥舞)andyelledatpassingcarsbutwascarefulnottoslowdown.答案：waved答案3．Thepieceofclothwillbecutupintothree________(套装)．答案：suits答案4．TheystudiedtheGermanmarkettofindthe________(可能性)thereforinvestment.答案：potential答案5．The________(实际的)causeofthequakeisthebreakingofrocksbelowtheearth'ssurface.答案：actual答案6．_________(爆发)ofvolcanoesisonewayofproducingthiskindofrocks.答案：Eruption答案Ⅱ.单句语法填空1．Wehumansareveryweakwhen________(compare)withsomenaturaldisasters.答案：compared答案2．Anagreementwasabouttobereached________theothersideraisednewissues.答案：when答案3．Heprotectedhishands________thecoldwithgloves.答案：from答案4．Thesoundofthecheeringfadedaway________thedistance.答案：in答案5．Ican'timaginemyself________(teach)infrontofthatmanypeople.答案：teaching答案6．(2018·菏泽期末)Frommyexperienceandaccordingtomyrough________(evaluate)Iknewthepricewastoohighforthatjacket.答案：evaluation答案7．Growingvegetableslookseasy,but________(actual)ittakesalotoftimetolearn.答案：actually答案8．(2018·辽宁抚顺期末)Therobotisequipped________amonitoringcamera(监控摄像头)andotherhardwareforfacialandvoicerecognition.答案：with答案[能力题]Ⅰ.阅读理解CouldtheDangerousUnderwaterVolcanoinCaribbeanCauseaUSTsunami?AteamofscientistsisexploringthedarkestcornersofahugeunderwatervolcanointheCaribbeaninhopesofbetterunderstandingthemysteriesofearthquakesandtsunamis,ultimatelysavinglives.Kick'emJennyisadangerousandactivevolcanosittingroughly6,000feetbelowthesurfaceoftheCaribbeanSea,andlocatedoffthecoastoftheislandofGrenada,southofSt.Lucia.RobertBallard,famousfordiscoveringtheTitanic12,000feetbelowthesurfaceoftheicyNorthAtlanticin1985,sethissightsonexploringtheKick'emJennytostudyitseruptionhistoryandlearnmoreabouthowunde
