中后面的例子是來證明人們設置密碼時往往會利用一些單詞的第一個字母作為密碼,E項符合此內容.4、通讀復檢，將所選答案代入文中，再次通讀全文，重點考查邏輯關系和關聯(lián)結構。在完成選項定位后，應通讀全文，檢查文章內容是否完整,語義是否連貫合理、各段落內容是否緊扣主題，語篇結構是否通順連貫、具有一致性、合乎邏輯,寫作思路是否清晰明了,格式以及用語是否恰當貼切，從而判斷選擇的答案是否正確。同時,我們還應注意對相近選項的對比分析，個別干擾項由于與某個正確選項的內容相近具有很強的干擾性，這時就需要我們認真分析，排除干擾，從而得出正確選項。5、確定排除，研究多余選項，確定排除理由，最終確定答案。第三部分語言知識運用(共兩節(jié),滿分45分）第一節(jié)完形填空（共20小題；每小題1.5分，滿分30分）閱讀下面短文，從短文后各題所給的A、B、C和D四個選項中,選出可以填入空白處的最佳選項.DavinaMcNaneyonFridaywillbeginajourneythatwillbringherhometoWayneCounty.Abreastcancer___21___，McNaney，42，willrun466milesfromMichigantoNewYorkinthenextfewweeksinan___22___toraisefundsandawarenessforbreastcancerresearch.“I’mjustaregularperson.”shesaid?！癐justwanttodo___23___tohelpothersandsetastrong___24___formygirls?！盩hemother___25___twoandUniversityofRochestergraduatechoseto___26___.herownpersonalultra-marathontoshowothershowgratefulshewasto___27___herillness.McNaneyhas___28___morethan$10，000fortheBreastCancerResearchFoundation，nearly___29___herinitial$5，000goal。Duringthefirstweek,McNaneyplanstorun36mileseachday。Two13—miledayswillfollowsoshe___30___celebratehereldestdaughter'seighthbirthdayand___31___hernephew’shighschoolgraduation.OnJuly3,the___32___dayofherjourney,McNaneywillrun22milesacrossWayneCountytoSodusPoint,___33___herdaughtersandmorethanahundredfriendswillbe___34___。HerhusbandSteve,35，willserveasherpitcrew。Itwillbehis___35___tokeepMcNaneyfed，totrackherweightandaddressany___36___problemsthatarise。Attimes，McNaneysaidshewillrunwith___37___—friendsinMichigan，acousininOhioandloadsoffriendsandrelativesinthefinalfewmilesinNewYork.Companywillbenice,shesaid,notingthatshe'salsolookingforwardto___38___timewhenshecanrelax,runand“justletmy___39___wander.”“IhopeIcanencouragepeopletochallengethemselves，toknowthattheycanovercomeinthefaceoftrouble，”McNaneysaid.“I’msteppingoutofmycomfort___40___andputtingmyselfouttheretoreachmygoal?！?1.A.expert
