“直到……”，与前面的not连用。答案：AⅤ.阅读理解WhatiseBay?Thesimpleansweristhatitisaglobaltradingplatformwherenearlyanyonecantradepracticallyanything.Peoplecansellandbuyallkindsofproductsandgoods,includingcars,moviesandDVDs,sportinggoods,traveltickets,musicalinstruments,clothesandshoes—thelistgoesonandon.TheideacamefromPierreOmidyar,whowasborninParisandmovedtoWashingtonwhenhewasstillachild.Athighschool,hebecameveryinterestedincomputerprogrammingandaftergraduatingfromTuftsUniversityin1988,heworkedforthenextfewyearsasacomputerengineer.InhisfreetimehestartedeBayasakindofhobby,atfirstofferingtheservicefreebywordofmouth.By1996therewassomuchtrafficonthewebsitethathehadtoupgrade(升级)andhebeganchargingafeetomembers.Joinedbyafriend,PeterSkoll,andin1998byhiscapableCEO,MegWhitman,hehasneverlookedback.Ecrashesofthelate1990s,eBayhasgonefromstrengthtostrength.ItisnowoneofthetenmostvisitedonlineshoppingwebsitesontheInternet.eBaysellsconnections,notgoods,puttingbuyerandsellerintocontactwitheachother.Allyouhavetodoistotakeane－photo,writeadescription,filloutasalesformandyouareinbusiness;theworldisyourmarketplace.Ofcourseforeachitem(商品)soldeBaygetsapercentageandthatisagreatdealofmoney.EverydaytherearemorethansixteenmillionitemslistedoneBayandeightypercentoftheitemsaresold.1．WelearnfromthetextthateBayprovidespeoplewith________.A．awayofbuyingandsellinggoodsB．awebsiteforthemtoupgradeC．aplacetoexhibittheirownphotosD．achancetobuythingsatlowprices2．WhydidPierrecreateeBayaftergraduatingfromuniversity?A．Forfun.B．Tomakemoney.C．Forgatheringtheengineers.D．Tofulfillataskofhiscompany.3．From“hehasneverlookedback”inParagraph2welearnthatPierre________.A．didnotfeellonelyB．wasalwayshopefulC．didnotthinkaboutthepastD．becamemoreandmoresuccessful4．HowdoeseBaymakemoneyfromitswebsite?A．Bybringingsellerstogether.B．Bychargingforeachsale.C．Bylistingitemsonline.D．Bymakinge－photos.答案与解析：文章向我们介绍了eBay网的一些情况。1．解析：推理判断题。根据第一段内容特别是由第三句话“Peoplecansellandbuyallkindsofproductsandgoods,includingcars,moviesandDVDs,sportinggoods,traveltickets,musicalinstruments,clothesandshoes—thelistgoesonandon.”可知人们通过eBay网买卖各种各样的产品和源源不断的商品。故选A。答案：A2．解析：细节理解题。由第二段第三句话“InhisfreetimehestartedeBayasakindofhobby,atfirstofferingtheservicefreebywordofmouth.”可知他在业余时间里，作为一种兴趣开创了eBay网，通过口头提供免费服务，故选A。答案：A3．解析：推理判断题。Pierre由原来的业余爱好开始，逐步走向成功，创建了世界知名网站。答案：D4．解析：细节理解题。由最后一段可知，这个网站通过提供交易平台，然后收取适当的服务费。因此B项正确。答案：B2Ⅰ.单句语法填空1．Whenweplanourvacation,motheroftenoffers________(practise)suggestions.2．Mybrother'splansarevery________(ambition);hewantstomasterEnglish,FrenchandSpanishbeforeheissixteen.3．—Jack,you________(want)onthephone.—________(come)．4．—Idon'tknow________itisthatmakesherdifferentfromothers.—Confidence,Ithink.5．Johnthinkitwon'tbelong________heisreadyforhisnewjob.6．Nowonderhiswifecomplainshim.Noonecanbearhim________(stay)athome,doingnothingdayafterday.7．Althoughmygrandfatherisinhiseighties,heisstillas________(energy)asayoungmanandhatessittingarounddoingnothingallday.8．Wefoundthemeetingroomthoroughly________(clean)andeverything________(arrange)ingoodorder.答案：wanted;Coming4．what;arrangedⅡ.用方框内短语的适当形式填空eq\x(diveinto，setout，associatewith，hangon，outoforder，getthrough，ringback，ringoff，everytime，beawareof)1．HoweverItriedtodialyournumber,Icouldn't________________.2．Just________________withit,andyouwillsucceed.3．Thewholethingswere________________，andmotherwasangry.4．She________________thewaterandcameupcoughing.5．Theshepherd(牧羊人)________________tolookforthesheepthathadwanderedaway.6．Hewasveryangryand________________beforeIfinishedmywords.7．Hewasverybusythenandpromisedto________________later.8．________________Ilistentoyouradvice,I'llgetintotrouble.9．Peopleofsimilartastesandhabitsliketo________________oneanother.10．Idon'tthinkpeople________________thedangerahead.答案：throughonoforderintooutoffbacktimewithawareofⅢ.完成句子1．Ican'tbear________________(人家叫我长时间等候)．2．You'dbetternotgooutbecause________________(外面非常冷)．3．Itriedringingyouseveraltimesyesterday,________________(可是都没接通)．(get)4．ThelinewasengagedandtheoperatoraskedifI'dlike________________(等一下)．(hang)5．Itisveryimportant________________(保持课堂秩序)．(order)6．Havingmadeuphismind,he________________(开始执行)theplan.7．________________(她跳入水中)excellentlywongreatcheers.8．Therearemanyserioushealthproblems________________(与吸烟有关)．9．I'll________________(不得不把电话挂上)now,Ihaveatraintocatch.10．Infactwe________________thecrime.(innocent)事实上，我们是无辜的。11．He________________theshoulder.(tap)他拍了一下我的肩膀。12．I'lltellhim__________________hegetshere.(moment)他一到这儿，我就告诉他。答案：1．beingkeptwaitingforalongtime2．it'sfreezingcoldoutside3．butIcouldn'tgetthrough4．tohangon5．tokeepclassinorder6．setaboutcarryingout或setouttocarryout7．Herdivingintothewater8．associatedwithsmoking9．havetoringoffinnocentof11．tappedmeonmomentⅣ.语法填空Marywillneverforgetthefirsttimeshesawhim.Hesuddenlyappearedinclassoneday,__1__(wear)sunglasses.Hewalkedinasifhehadboughttheschool.Andthewordquicklygotaround__2__hewasfromNewYorkCity.ForsomereasonhesatbesideMary.Maryfelt__3__(please),becausethereweremanyemptyseatsintheroom.Butshequicklyrealizedthatitwasn'ther,it
