疲劳，甚至会使人感到头晕、恶心等。文章最后告诉我们，近视跟遗传有很大的关系。64．B。细节理解题。由第二段的第一句话(Whentheeyeadjuststolowerlevelsoflight，musclesaroundtheirisrelaxandallowthepupiltodilatesothatmorelightwillenterandhitthebackoftheeye．)可知，当眼睛去适应昏暗的光线时，虹膜周围的肌肉便会放松，然后瞳孔便放大，于是会有更多的光线到达眼睛的后部。所以B项正确。A项将过程说反厂。65．B。细节理解题。由第三段的最后一句话(．．．thereasonbeingthattheybecometensefrommusclesOfeyesthatareworkingharderthannormaltofocusimages．)可知，在昏暗的灯光下读书时，眼睛周围的肌肉工作强度更大.故B项符合题意。66．B。根据最后一段第二句话(Duringthefirstdecadeoflife，theeyeschangeslightlyinshapeandsize，significantlyimpactingonhowtheeyesfocus．)可知，在生命的前十年里，眼球的形状和大小会发生细微的变化，这极大地影响了眼球的聚焦方式。由此可知生命的前十年对人的眼睛是非常重要的。所以B项正确。67．A。综合全文内容可知，在昏暗的灯光下看书，虽然会导致眼睛疲劳，甚至会使人感到头晕和恶心，但并非必然导致近视。其他选项与文章不符。[解题导语]文章列举了不同的人对网络游戏的不同看法，孩子玩暴力游戏是否真的会变得比较暴力?不同的人有不同的看法。[长难句解读]BlamingchildrenbeingviolentOngamesandsuchisn’tright．动名词blamingchildren用作句子的主语；短语beingviolenton．．．是非谓语作后置定语。68．B。本题考查文章的主旨大意。从全文来看，作者列举了许多人对网络游戏的评论，故B为正确答案。69．D。本题考查推理判断。从第一段中“IshouldhaveplayedthegamesIwroteaboutfirst．．．Iapologizeformakingmistakes．．．”可知，人们对上一个电子游戏故事是不满意的，故答案选D。70．B。推理判断题。文中第二段中一些人认为电子游戏也应当像电影一样分级，家长有责任不让孩子接触M级的电子游戏；一些人认为孩子们能够而且应该分清什么是真实的生活什么是虚幻的东西；还有许多人很难相信电子游戏与孩子们的暴力行为有关系。故可以知道人们对电子游戏的看法是不同的。（二）ARecentrumors(流言)aboutthatChinesedivingqueenGuoJingjingwillmarryKennethFoknextmonth,buttheseweredeniedbybothKennethandhisfatherFokTsun-TingonFridayafternoon,.SinacontactedboththefatherandsonthisafternoontoseekcommentandwastoldbyKenneththatthecouplehavemadenosuchplans.Hisfatheralsodeniedtheyhadalreadysentoutweddinginvitations.Therumorwasleakedfrom‘Wenweipo’,oneofHongKong'smainstreamnewspapers,andsoonaftermadeheadlinesonthemainland.ThearticlequotedsourcesassayingChinesedivingqueenGuoJingjingwillmarryKennethFokKai-kong,thegrandsonofthelateHongKongbusinesstycoon,HenryFok,inmid-nextmonth.It’sbelievedthattheFokfamilyprefertokeepalowprofileandavoidmediaspeculationaboutthewedding.However,unidentifiedsourceshavedisclosedthatmanyfriendsoftheFokfamilyhavealreadyreceivedweddinginvitations.It’salsobeensuggestedthatGuowillmoveinto‘FokVillas’inHongKong'sSassoonRoad,whereHongKong'swealthyreside,afterthemarriage.Reportedly,KennethFokisassistingGuotoobtainaHongKongIDviatheQualityMigrantAdmissionScheme.Inspiteoftherumorsaboutthewedding,somepeopledoubtwhetherthenewsistrue,sayingitisjustmediaguess.LastSeptember,arumoremergedthatGuowassufferingfromadetachedretinabutitwaslaterdeniedbyGuoherself.Meanwhile,ZhouJihong,teamleaderoftheChinesediving“dreamteam”revealedinarecentinterviewthatshehasnoideaaboutGuo’sso-calledimpendingwedding.EarlierthismonthGuocompletedthenationaldivingchampionshiptournamentinFuzhou,southeastChina’sFujianprovince,andhasnootherdivingcompetitionsscheduledinthenearfuture.Questions:1.Accordingtothepassage,whatstatementisnottrue?A.FokTsun-Tingdeniedtheyhadalreadysentoutweddinginvitations.B.TherumorwasleakedfromC.theFokfamilyprefertokeepasecretaboutthewedding.D.ZhouJihongknewnothingaboutGuo’swedding.2.whatproofsareprovidedinthepassagetoproveGuo’sweddingexcept_______?A.UnidentifiedsourceshavedisclosedthatmanyfriendsoftheFokfamilyhavealreadyreceivedweddinginvitations.B.It'salsobeensuggestedthatGuowillmoveinto'FokVillas'inHongKong'sSassoonRoadC.Reportedly,KennethFokisassistingGuotoobtainaHongKongIDviatheQualityMigrantAdmissionScheme.D.LastSeptember,arumoremergedthatGuowassufferingfromadetachedretina.3.What’sthemeaningoftheword“emerged”?A.revealedB.reported.C.deniedD.admitted答案：BDA1.从文章第三段可知B项错误。2.从文章倒数第三段可知。3.该词所在的句子讲的是流言的内容，因此推测出谓语动词的意思。B.WallStreetendsinredinchangingsession(交易日)ByAlistairGrayandAnujGangaharinNewYorkPublished:October17200813:54|Lastupdated:October17200821:44AwildweekforWallStreetstocksthatsawtheirbiggestgainsincetheDepressionandworstsell-offsince1987drewtoaclosewithanotherchangingsessionthatendedinthered.Themarketswungbetweengainsofasmuchas4percentandlossesthathit2.9percent.TheS&P500closeddown0.6percentat940.56points.TheNasdaqwasdown0.4percentat1,711.29points,andtheDowwasdown1.4percentat8,852.22points.Yetthebenchmark（基准）S&Pstillfinishedtheweekup4.6percentitsbiggestgainsinceIraqwasoccupiedin2003withtheNasdaqup3.7percentandtheDow4.7percenthigher.Financialsclimbed5.8percentovertheweek,liftedbythefresh$250bnplantosupportUSbanks.Banks,likeBankofAmerica,GoldmanSachsandCitigroupamongthebiggestinwhichthegovernmentissettobuystocksadvanced11.4percentto$23.24,28.7percentto$114.30and5.5percentto$14.88respectively(分别地).TheChicagoBoardOptionsExchangeVolatilityindex(指数)increasedover80forthefirsttimeinits18-yearhistory.However,itfinishedtheweekdown1.2percentat69.45.TechnologystocksweredownafterthreecompaniesreportedbetterthanexpectedresultsafterthebellonThursday.Googlerose5.5percentto$372.54aftertheinternetsearchgroup’sprofitssurpassedWallStreetforecasts.AdvancedMicroDevicesandIBMadded2.2percentto$4.21andlost0.8percentat$90.78afterbothsurprisedWallStreetwiththird-quarterearningsaheadofexpectations.EricSchmidt,chiefexecutive,warnedofuncertaintyduetothefinancialstorm.1.Whatcanweinferfromthefirstparagraph?A.Theweekpassedpeacefully.B.MostpeopleinWallStreetprobablymadeprofits.C.Mostpeop
