B.has;lost

C.will;lose

D.does;lose首先C.和D肯定不正确，不可能预测以后的事，也不可能总是丢东西；在A和B中，主要是询问这个动作什么时候发生的，而没有涉及与现在的联系。【课后练习】一、根据句意及中、英文释义完成单词1.Ihavelookedfortheir________(护照)everywhere,butstillcan’tfindthem.2.PandasarefromChina.Koalasarefrom________(澳大利亚).3.SheislookingupanEnglishwordinan________(在线的)dictionary.4.Guangdongisoneofthe________(贸易)centresinChina.5.Ifeelsotired,soIreallywantto________(放松)myself.6.It’seasytoloseyourwayinsuchabigcitywithouta________(导游).7.Everyday,manytourists________(toetogetherandformagroup)atTian’anmenSquaretowatchtheraisingofthenationalflagearlyinthemorning.8.TheUnitedNationsisan________(国际的)organization.9.Seeingtheoldmengetonthebus,________(afew)studentsofferedthemtheirseats.10.RomeoandJulietisoneofthemostfamous________byShakespeare.二、用所给词的适当形式填空1.Ithinkthisbookisvery________(bore).2.Wouldyoumind________(give)meaglassofwaterandsomebread?3.NewYorkisthe________(big)cityintheUSA.4.HisunclewantstogotoBeijingfor________(far)study.5.Arethereany________(internationally)banksinyourtown?6.Theartistdoesn’tpaintformoneybutforhisown________(please).7.Thisfactorywassetupintheearly________(twenty)century.8.Mycousinhasn’tgotusedtothelifeinthis________(Europe)countryyetsincehecamehere.9.Thelampsintheofficesuddenlywentout,leavingtheworkersin________(dark).10.Helikedthewideopenspacesofthe________(Australia)countryside.三、选择所给动词的适当形式填空read,learn,do,spend,be1.I________tothePalaceMuseumwithmyparentstwice.2.Mysisterisveryhappythatshe________toswim.3.Myfamily________aweekinNanjinglastsummer.4.I________20pagesofthisbookyesterday.5.________you________yourhomeworkat8o’clockyesterdayevening?四、单项选择()1.Thewebsitecalled“AroundChinainTenHours”isabout________onlinetour.________tourhas10levels,withlotsofusefulinformation.
