文档简介

学霸学习提醒一、课本是最好的老师。要注重基础,反复研读课本,巩固基础知识。二、要养成良好的学习习惯。良好的学习习惯是高效率掌握知识的保障。三、要保持良好的学习状态,自信踏实,刻苦努力,以饱满的精神迎接新一天的挑战。四、课堂上:专心听讲是第一位。事实证明,自以为是的确是不好的习惯。同样的例题,自己看懂与听老师讲懂是完全不同的两种效果。五、建议同学们在课外多投入些时间做题,并且要从心里重视数学。还应该准备一个错题本,老老实实地将每次错过的题抄在上面,并写上正确的解题思路,变不懂为精通。特别提醒:请学习稍差的同学一定不要放弃,哪怕到最后一学期,也不能放弃。只要按照老师说的去做,只要塌实地付出了,就一定会有奇迹出现。永远不要放弃拼搏,因为奇迹只发生在相信奇迹存在的人身上第1页/共11页□.GrammarandVocabularySectionADirections:Afterreadingthepassagebelow,fillintheblankstomakethepassagescoherentandgrammaticallycorrect.Fortheblankswithagivenword,fillineachblankwiththeproperfromofthegivenword;fortheotherblanks,useonewordthatbestfitseachblank.IsHothouseEarthAvoidable?Nearly50yearsago,theClubofRome,sreport“LimitstoGrowth”warnedthatifeconomicgrowthcontinuedfastwithoutregardfortheenvironment,theworldcouldfaceecologicalandeconomiccollapseinthetwenty-firstcentury.Yetthatisessentially(21)hashappened.AsnewresearchfortheClubofRomeshowsandthelatestreportfromtheUnitedNationsIntergovernmentalPanelonClimateChange(IPCC)statestheworld(22)wellbeheadedtowardsdisaster.Manywrongly(23)(interpret)the“LimitstoGrowth”asanstackonuncontrolledeconomicexpansion.Infact,thereportarguedthat(24)theunlimited-growthpathwaywaschosen,itwouldrequirecomplementarypolicies(includingfunding)(25)(preserve)theplanet,slimitedlife-supportsystems.Thisargument(26)(ignore).Instead,theworldhascontinuedtopursuefastgrowth,withoutregardfortheenvironmentalconsequences.Thishasenabledustomakeenormousprogressinreducingpoverty,increasinglongevity,andincreasingwealth.(27)ithascomeatahighcosttotheformationofthesocietyandtherestorationoftheplanet.Asscientistshaveconclusivelyshown,inthelastdecade,wehaveenteredanewgeologicalear,theAnthropocene,inwhichhumanactivity-inparticular,economicactivityhasbeenthedominantfactor(28)(influence)Earth,sclimateandenvironment.IntheAnthropocene,ourplanet,slife-supportsystemischangingfasterthanever.Climatechangenowrepresentsaclearandpresentdanger.Ifourplanetbecomesjust2℃Warnerthanpre-industrialtemperatures,wemaybeplacedirreversiblyonthepathtoward“HothouseEarth”asituation(29)temperaturesaremanydegreeswarmerthantoday,sealevelsareconsiderablyhigher,andextremeweathereventsare(30)(common)andmoredestructivethanever.SectionBDirections:Completethefollowingpassagebyusingthewordsinthebox.Eachwordcanonlybeusedonce.Notethatthereinonewordmorethanyouneed.A.processedB.increasingC.applicationsD.typingE.interpretingF.reflected
