eryfivetoeightyears.(happens是谓语动词，也可知前面为名词短语，缺一个核心名词。)47.Fphenomenon介词后面必有名词Asthetradewindslessenin48,theoceantemperaturesrise,causingthePerucurrentflowinginfromtheeasttowarmupbyasmuchas5°C.(在介词in的后面，当为名词无疑，此处整个短语来修饰lessen减少，当为在某个方面减少。)48.Bstrength(二)句里句外，猜测词义一看搭配：主谓宾、主系表与修饰词直接的搭配关系决定着词的意义。所以先看它被谁修饰，与谁形成主谓宾关系。看一种关系不行就看另一个，灵活处之。Thisstrange47happenseveryfivetoeightyears.strange修饰47，也许看不出来是什么，再看47与happen形成主谓关系，能够发生的是什么最好的当然是现象。47.Fphenomenon二看逻辑：1.句内(状语从句，解释，并列等)Asthetradewindslessenin48,theoceantemperaturesrise,causingthePerucurrentflowinginfromtheeasttowarmupbyasmuchas5°C.此句有一个状语从句，as表示的时间或因果关系，是重要的解题线索。风的什么减少，温度就上升，当然是风的速度或风力。48.BstrengthSowhilesomepartsoftheworldprepareforheavyrainsandfloods,otherpartsfacedrought,poorcropsand51.空格与前面两个名词并列，意味着意思相近。与干旱、收成不好一致的，很容易选出starvation饥荒.51.Kstarvation2.前文(指代等、句间连词)Thisstrange47happenseveryfivetoeightyears.This告诉我们，此处是重提前面讲到过的某个东西。前面讲到过的核心概念就是ElNino,无疑是一种天气“现象”。47.Fphenomenon表示可从前文找相应线索的有两类。与this一大类的还有：This/these/such;thesame/similar;worse/better/more/less等。还有就是表示逻辑关系的句间连词，或者叫连接副词。主要的如下。递进：Moreover/furthermore/what’more/besides/inaddition/even/also转折：however/but/rather/instead因果：therefore/consequently/accordingly/thus/hence3.后文ElNinousuallylastsforabout18months.The1981-83ElNinobroughtthemost52weatherinmodernhistory.Itseffectwasworldwideanditleftmorethan2,000peopledeadandcausedovereightbillionpounds53ofdamage.段落开始部分，提出一个总的概括性的说法。往往在下文有分述。ElNino究竟带来的是什么样的天气，后面一句就交代得十分清楚。52.Jdestructive(dead,damage)三看习惯用法：固定搭配Itseffectwasworldwideanditleftmorethan2,000peopledeadandcausedovereightbillionpounds53ofdamage.53.Nworth此处考的是worth这个词的特殊用法。它本是一个形容词，但可用…worthofsth,来表明价值某物的某东西。e.g.Thefirecausedthousandsofpounds'worthofdamage.America'smostfamouswomanistheGoddessofLiberty,i.e.theStatueofLiberty.Itwasfirstthoughtofin1865byEdouarddeLaboulayeanddesignedbyanotherFrenchman,FredericBartoldi.Theywantedto11libertyandfriendship.Itwashopedthatthemonumentwouldbecompletedby1876whenAmerica12itscentennial.Fundraisingandthe13ofthestatueinFrancewentslowly.Itwas1885whenthe214cratescontainingthestatuereachedNewYork.Americanswereinitially14fortheyhadnotraisedthemoneytopayfortheerectionofthebase.Fundraisingbypopularsubscriptionwasbehind15.OnefundraisingmethodusedwastohavepopularAmericanswriteletterswhichwerethensoldinpublic.Thebaseandstatue,16272feettall,werecompletedin1886.Froma17standpoint,thestatueisamarvel.TheinnerstructurewasdesignedbytheFrenchengineer,AlexandreEiffel.Hisdesignforthestressedcopperskinofthestatueanticipatedmanyofthe18utilizedinmodernaircraft.Afteracentury,themonumentbegantoshowsignsofgettingworsein19.JustasFrenchmenhadcreatedtheStatue,soitwaswithrestoration.AFrenchmannotedthedecayandFrenchandAmericancraftsmenandcontributionsbroughtabouttherenewaloftheStatueintimeforitscentennial.Libertyisstill20inFranceandtheUnitedStates.A.completelyB.measuresC.popularD.togetherE.honorF.manufactureG.scheduleH.rewardI.celebratedJ.principlesK.embarrassedL.technicalM.voluntaryNconditions0.discouraged答案：11.E12.I13.F14.K15.G16.D17.L18.JTheLouisianaPurchaseOnApril30,1803,theareaoftheUnitedStatesapproximatelydoubled.Untilthattime,UnitedStatesterritoryhadextendedfromtheAtlanticOceantothebanksoftheMississippiandfromtheGreatLakesandtheSt.LawrenceRivertothethirty-firstparallel.ThenationallandnowwasexpandedwestwardtoincludepracticallyalloftheareabetweentheMississippiRiverandtheRockyMountainsandbetweentheGulfofMexicoandtheCanadianborder.Onthatday,forfifteenmilliondollars,theUnitedStatespurchasedfromFrance875,000squaremilesofterritory.AfterRobertR.Livingston,anAmericanwhorepresentedPresidentJeffersoninFrance,signedhisnametothetreaty,herose,shookhandswithJamesMonroeandMarbois,theFrenchmanrepresentingNapoleonandremarked,"Wehavelivedlong,butthisisthenoblestworkofourlives."Asweglancebackwarduponthisimportanteventinhistory,wemustagreethatthesigningofthetreatyforthepurchaseofLouisianawasprobablythemostimportanteventinThomasJefferson'sadministration.Withouttheacquisitionofthisterritory,theUnitedStateswouldmostprobablyhavenotdevelopedintothepowerfulnationwhichitistoday.WhatCausesLedtoPurchaseoftheLouisianaTerritoryUntil1763,LouisianahadbeenapossessionofFrance,butinthatyearitwasgiventoSpaintorepayanolddebt.TwentyyearslaterinParis,thetreatyendingtheAmericanRevolutionwassignedbetweentheUnitedStatesandGreatBritain.OneofthetermsofthistreatywasthatthewesternborderoftheUnitedStateswastostretchtotheMississippiRiver.ImmediatelysettlersandpioneerscrossedwestwardovertheAlleghenyMountainstocleartheterritoryandestablishfarms.Sinceroadswerescarceanddifficulttotravel,theproductsofthesefarmershadtobeshippedonthewaterwaysleadingtotheMississippiRiverandthendownthisgreatstreamtoNewOrleans.Atthisportcity,theproducewastransferredtolargerocean-goingvesselsandtransportedtomarketsontheEasternSeaboardortoEurope.However,Spain'sownershipofbothshoresoftheriverforatleasttwohundredmilesnorthofNewOrleanspermittedthisforeignnationtocontrolthetrademovingontheMississippi.Asamonarchy(君主政体)，theSpanishgovernmentdistrustedtherisingspiritofdemocracyintheUnite
