托福TPO26综合写作阅读+听力原文+满分范文【雷哥托福整理】雷哥托福小托君给大家分享TPO1-33综合作文部分的阅读和听力文本全集与综合作文的满分作文，以及满分作文的解析。如果自己的托福综合作文分数如果可以很给力的话，就已经搞定了15分的分数，可以极大地缓解托福独立作文的压力。如何使用这个文件呢？首先，就是在自己做托福TPO模考之后，可以根据这里面的听力的文本，来检验自己的听力内容是否抓的足够好，尤其是要看写的够不够全！很多时候，我们的综合作文之所以分低，就是因为听力写的不全！第二点，也可以用于在托福考试前来做跟读，有不少托福考生跟小托君说，自己的口语实力不够，那么做跟读，仔细地来模仿ETS官方素材，是一个很好的提高自己口语的方式。毕竟托福口语最终考的，是口语本身说的是否足够流畅，要想在考试的时候说的很流畅，就是要在平时张口多说，只有多说，我们才能够做到足够的流利。第三点，熟悉托福考试的专业词汇。不少托福考生之所以在听力考试里面不够给力，是因为对于里面的专业词汇不够熟悉。毕竟在托福考试过程中，如果核心词汇都不懂的话，那么在听力部分只能是束手就擒了。因此，各位托福考生可以通过这份综合写作的听力和阅读材料，来熟悉托福作文之中的专业词汇。TPO26综合写作听力+阅读原文ReadingThezebramussel,afreshwatershellfishnativetoEasternEurope,haslongbeenspreadingoutfromitsoriginalhabitatsandhasnowreachedpartsofNorthAmerica.TherearereasonstobelievethatthisinvasioncannotbestoppedandthatitposesaseriousthreattofreshwaterfishpopulationsinallofNorthAmerica.First,thehistoryofthezebramussel'sspreadsuggeststhattheinvasionmightbeunstoppable.Itisaprimeexampleofaninvasionmadepossiblebyhumantransportation.Fromthezebramussel，soriginalhabitatsinEasternEurope,shipshelpedspreaditoutalongnewcanalsbuilttoconnectEurope’swaterways.Themusselcanattachitselftoaship’sbottomorcansurviveinthewater—calledballastwater—thattheshipneedstotakeontoproperlybalanceitscargo.Bytheearlynineteenthcentury,themusselhadspreadtothewholeofEurope.ItwaslatercarriedtotheeastcoastofNorthAmericaintheballastwaterofshipstravelingfromEurope.ThewayshipshavespreadthezebramusselinthepaststronglysuggeststhatthespecieswillsooncolonizeallofNorthAmerica.Moreover,oncezebramusselsarecarriedtoanewhabitat,theycandominateit.Theyareahardyspeciesthatdoeswellunderavarietyofconditions,andtheyhaveahighrateofreproduction.Mostimportant,however,zebramusselsoftenhavenopredatorsintheirnewhabitats,andspecieswithoutnaturalpredatorsarelikelytodominatetheirhabitats.Finally,zebramusselsarelikelytocauseadeclineintheoverallfishpopulationinhabitatswheretheybecomedominant.Themusselsareplanktoneaters,whichmeansthattheycompeteforfoodwithmanyfreshwaterfishspecies.ListeningNowlistentopartofalectureonthetopicyoujustreadabout.ProfessorContrarytowhatyoujustread,therearewaystocontrolthezebramussel'sspread.What'smore,itisnotsoclearthatthemusselisaseriousthreattofishpopulations.True,thespreadofzebramusselscouldn'tbecontrolledinthepast,butthat'sbecausepeopledidn'thaveenoughknowledge.Infact,thereareeffectivewaystostopshipsfromcarryingthemusselstonewlocations.Here'sanexample.ThewayzebramusselsusuallytravelacrosstheoceanisthatashiptakesonsomefreshballastwaterinEuropeandthenemptiesthatwaterintoAmericanwaterwayswhenitarrives.Fullofzebramussels,buttheshipcanberequiredtoemptyoutthefreshwaterandrefillwithoceanwaterwhilestilloutintheocean.Saltwaterwillkillthemussels.Second,it'struethatzebramusselsoftendon'thavepredatorsintheirnewhabitats,butthat'sonlyinthebeginning.What'sbeenhappeninginEuropeisthatlocalaquaticbirdssoonerorlaternoticethere'sanewfoodsourcearoundandchangetheirhabitstoexploitit.Theyswitchfromwhatevertheywereeatingbeforetoeatingzebramussels.Andbirdscaneatalotofmussels.Sozebramusselsaren'tsolikelytodominatetheirnewhabitatsafterall.Finally,eveninhabitatswherezebramusselsbecomedominant,istheoverallfishpopulationlikelytodecrease.It'struethatzebramusselsmayhaveanegativeimpactonfishthateatplankton.Butonotherfish,theycanhaveapositiveimpact.Forexample,themusselsgeneratenutrientsthatareeatenbyfishthatfeednearthebottomofthelakeorriver.Sobottom-feedingfishpopulationsmayincrease,evenifplankton-eatingfishpopulationdecrease.由于篇幅有限，托福综合写作满分范文，在雷哥托福微信公众号获取
