indonwhatyouwhattodreamabout可以推断本段内容是建议人们要把留意力集中到自己想要梦到的事情上,和G选项中Payattentionto全都。3.E本段提出的建议是为了要记住自己做的梦,要给自己一个示意,从前后句内容推断E选项内容Youmustwanttorememberyourdreams.恰好是给自己的示意信息,答案选E。4.A本段中Planonwakingupslowlyandpeacefully.是主题句,建议人们要缓慢,平和地醒来。而A选项Trytowakeupnaturally也是让人们要自然醒来,内容可以承接上文,选A。5.C本段内容是关于养分和健康饮食的,也就是说健康对于睡眠做梦都是有影响的,由此推断C选项内容Yourhealthisveryimportant.可以概括本段中心,能作为主题句毁灭,选C。Ⅲ.语法填空Arecentincidentismakingheadlinesonvariouswebsites:LiangYa,afemaleworker,__1__(faint)inasubwaystationinShenzhen,andwasconfirmed__2__(die)whenambulancesarrivedabout50minuteslater.Somewhocommentedblamedpassersby__3__beingcoldblooded,butsuchaccusationsaregroundless,saysaneditorialinTheBeijingNews.While__4__(report)theincident,severalwebsitesusedheadlinessuchasFivePassbyWithoutLendingaHelpingHand.Theseheadlinespromptedirrationalreaderstoblamethepassersby,asiftheywere__5__(responsibility)forLiang'sdeath,saystheeditorial.__6__analysisofthedetailsrevealshowgroundlesstheseclaimsare.ThemonitorvideoofthesubwaystationshowsthatLiangfaintedandfellat10:29a.m.andthreeminuteslaterapasserbyfoundherandinformedthesubwaystaff.Theystood__7__herandcalledthefirstaidcenter11minuteslater,butwhentheambulancearrivedat11:18,Liangwaspronounceddead.__8__(obvious),saystheeditorial,__9__thepassersbydidwasrightwithoutanyprofessionaltraining,itisnotadvisabletointerveneinsuchincidents,__10__couldbelifethreatening.答案与解析1.fainted依据上下文可知用一般过去时。2.dead形容词作补语。3.forblamesb.forsth.因……而责怪某人。4.reportingwhiledoingsth.当在做某事时。5.responsibleberesponsiblefor对……负责。6.An该空表示“一个”,故用不定冠词。7.bystandby旁观,站在……旁边。8.Obviously副词作状语。9.whatwhat引导主语从句,在从句中作宾语。10.whichwhich引导非限制性定语从句,在从句中作主语。Ⅳ.短文改错Thismorning,Iwenttoschoolbybicycleasusually.AsIwaslisteningtomyfavouritemusicwithaheadphoneonmyhead,Idon'tnoticeacarparkedontheroadside.Ihitthecarorleftascratchonit.ThinkthatIwouldhaveclasses,Ileftanotewithmynameandaddresstoletthedriverknowwhichhappened.Laterintheafternoon,whilewewerehavingaclassmeeting,ourheadmasterbroughtstrangertoourclass.Hewasthecarowner.Heexplainedtotheclassthewholestoriesandpraisedforme.Myteacherandclassmateswasimpressedandproudofhishonesty.Ithinkhonestyshouldbevaluedmost.答案Thismorning,Iwenttoschoolbybicycleaseq\o(usually,\s\do14(usual)).AsIwaslisteningtomyfavouritemusicwithaheadphoneonmyhead,Ieq\o(don't,\s\do14(didn't))noticeacarparkedontheroadside.Ihitthecareq\o(or,\s\do14(and))leftascratchonit.eq\o(Think,\s\do14(Thinking))thatIwouldhaveclasses,Ileftanotewithmynameandaddresstoletthedriverknoweq\o(which,\s\do14(what))happened.Laterintheafternoon,whilewewerehavingaclassmeeting,ourheadmasterbroughteq\o(∧,\s\do14(a))strangertoourclass.Hewasthecarowner.Heexplainedtotheclassthewholeeq\o(stories,\s\do14(story))andpraisedeq\o(for,\)me.Myteacherandclassmateseq\o(was,\s\do14(were))impressedandproudofeq\o(his,\s\do14(my))honesty.Ithinkhonestyshouldbevaluedmost.Ⅴ.书面表达假定你是星光中学的高中毕业生李华,母校将为高一新生举办主题为“Whattolearninseniorhighschool?”的英语沙龙活动,特邀请你结合自身经受谈谈自己的体会。请依据以下提示预备一份英语发言稿。1.学会学习:方法,习惯等;2.学会做人:真诚,友善;3.学会其他:考生自拟。留意:1.词数100左右;2.发言稿开头和结尾已给出,不须抄在答题卡上,不计入总次数。Goodmorning,everyone!Itismyhonortobeheretosharewithyoumyopinionsonwhattolearninseniorhighschool._________________________________________________________________________________
