B．Sad.C．Ashamed. D．Indifferent.答案：A解析：推理判斷題。根據(jù)第四段中Whilesuchgatheringshadgrowninfrequent,wewereallhappytobetogether.可知，雖然這樣的聚會越來越少了，但我們都很高興能在一起。由此推測作者喜歡和親人聚在一起，對于自己擁有一個大家庭這件事是高興的，故選A項。2．Whatcanweinferfromthelasttwoparagraphs?A．Theauthor'sfamiliesoftengettogether.B．Allthefamilymembershaveetothegathering.C．Theoldcousinwhotaughttheauthorpianodidn'tlikehim.D．Theauthorandhislargefamilymemberscherishthebondbetweenthem.答案：D解析：推理判斷題。根據(jù)最后兩段內容可知，雖然像這樣一大家子聚在一起的機會越來越少了，但作者他們都很高興能在一起。作者能夠輕易地認出來大多數(shù)親戚。當聚會結束，最后一組尾燈消失在夜色中時，天已經(jīng)很黑了。當作者收拾好東西，說再見，準備離開的時候，一個表哥打給他，說：“別忘了你來自哪里?！彼卮鸬健拔矣肋h不會。我永遠不會嘗試”。從作者能夠認出大部分親戚，表哥打給作者說的話以及作者的回答等可以推斷出作者和親戚都很珍惜他們之間的關系，故選D項。3．Whydoestheauthorwritethispassage?A．Toparethesmallfamilieswithlargeones.B．Tosharehisfeelingaboutlargefamily.C．Toshowhisworryabouttheshrinkingoffamilysize.D．Togiveadviceoffamilyrelationships.答案：B解析：推理判斷題。根據(jù)文章內容可知，雖然世界各地的家庭規(guī)模都在縮小，意味著很多孩子在成長過程中很少有表親。但作者很難想象這個，因為他來自于一個大家庭。作者描述了來自于一個大家庭是怎么的經(jīng)歷，并著重描寫了在表親家的一次聚會，展現(xiàn)了與親戚之間的感情紐帶。由此可知，作者寫這篇文章是為了分享他對大家庭的感受，故選B項。BHowsomepaniesfightthecurse(禍害)ofpresenteeism(超時工作)?RonaldReaganfamouslyjokedthat“it'struehardworkneverkilledanybody,butIfigure,whytakethechance？”Beyond_a_certain_level,_extra_effort_seems_to_be_self-defeating.Studiessuggestthat,afteraround50hoursaweek,employeeproductivitydeclinessharply.Butthatdoesn'tstopsomemanagersfromdemandingthatworkersstaychainedtotheirdeskforlongperiods.JackMa,thefounderofAlibaba,theChinesee-mercegroup,recentlypraisedthe996model,whereemployeesworkfrom9amto9pm,sixdaysaweek,asa“greatopportunity”.Yetpresenteeismisthecurseofthemodernofficeworker.Therewillbedayswhenyoudonothavemuchtodo;perhapsbecauseyouarewaitingforsomeoneelseinadifferentdepartment,oradifferentpany,torespondtoarequest.Astheclocktickspast5pm,theremaybenopurposeinstayingatyourdesk.Butyoucanseeyourbosseshardatworkand,moreimportantly,theycanseeyou.Soyoumakeanefforttolookbusy.Theconsequenceisoftenwastedeffort.Ratherthanworkhard,youslavetomakebossesthinkthatyouare.Butpresenteeismhasmoreseriousconsequences.Aswellasreducedproductivity,thiscanmeangreatermedicalexpensesfortheemployer.AccordingtoastudyintheJournalofOccupationandEnvironmentalMedicine,thesecostscanbesixtimeshigherforemployersthanthecostsofabsenteeismamongworkers.Noneofthisistosaythatemployersarenotcalledtoexpectworkerstobeintheofficeforaproperperiodoftime.Surelytherewillbeaneedforsome(preferablyshort)meetings.Dealingwithcolleaguesface-to-facecreatesafeelingoftogetherness,allowsforausefulexchangeofideasandenablesworkerstohaveabettersenseoftheirmutualneeds.Turninganofficeintoaprison,withinmates(囚犯)allowedhomefortheevenings,doesnothingforcreativitythatisincreasinglydemandedofofficeworkersasroutinetasksareautomated.Tobeproductiveyouneedpresenceofmind,notjustbeingpresentintheflesh.本文是一篇議論文，作者在文中論述了超時工作的負面影響，包括降低生產(chǎn)效率、增加成本等。4．WhydeostheauthormentionRonaldReagan'sjokeinPara.1?A．Toencouragepeopletograspthechancetoworkhard.B．Toshowthathardworkisharmless.C．Tointroducethetopicofthepassage.D．TopraiseRonaldReagan'sjokingskills.答案：C解析：推理判斷題。通讀全文可知，文章的主題是論述超時工作的負面影響。從結構上來看，作者在第一段用羅納德·里根曾說過的一句著名的俏皮話點題(為什么要冒險加班工作)，下文則緊接著論述讓員工超負荷工作產(chǎn)生的各種負面影響，由此可推知作者在第一段提到里根的話是為了引出文章主題。故選C。5．Whatisthemeaningoftheunderlinedsentence?A．Extraeffortcausesproblemsordifficulties.B．Withextraeffort,wecandefeatanybody.C．Weshouldsaynotoextraeffort.D．Extraeffortisn'tnecessarilyhelpful.答案：D解析：句意理解題。根據(jù)上文羅納德·里根的俏皮話可知，沒有必要冒險努力工作；下文表明，一周工作50個小時后，員工的生產(chǎn)力會急劇下滑，由此可推知畫線句表示超過一定水平后，多余的努力會適得其反，故選D。6．Accordingtothepassage,whichofthefollowingsituationishelpfultothepany?A．Yourteamhasaten-minutemeetingafterworkforanurgentproblem.B．Youdon'tgohomeuntil7：30pmbecauseyourbossisinhisofficeandhecanseeyou.C．Themanagertourstheengineeringdepartmentat7：30pmtocheckpeopleareattheirdesks.D．Youattendtheofficeevenwhenyousufferlowerbackpain.答案：A解析：推理判斷題。根據(jù)倒數(shù)第二段中的“Surelytherewillbeaneedforsome(preferablyshort)meetings”可知，開會(最好是短會)對公司是有必要的，故選A。7．Whichofthefollowingopinionsagreeswiththepassage?A．Somemanagersexpectworkerstiethemselvesupwithachaintotheirdesks.B．Reducedproductivitycanmeangreatermedicalexpensesfortheemployer.C．Withgrowingdemandofcreativityonofficeworkers,aprison-likeofficeisnotawiseoption.D．Presenceofmindguaranteesyourproductivity.答案：C解析：細節(jié)理解題。根據(jù)尾段第一句可知，把辦公室變成監(jiān)獄對(員工的)創(chuàng)造力毫無益處，故選C。Ⅱ.七選五Manypeoplebelievethatthereissometruthinthesaying,“Laughteristhebestmedicine.”__1__Laughterhelpsrelievepain,strengthentheimmunesystemandreducestress.Laughterstimulates(激發(fā))hormoneswhichmakeusfeelhappy.Laughteralsoincreasestheflowofbloodthroughoutthebodyandhasbenefitswhicharesimilartotheonesyougetbydoingexercise.__2__Childrenexposedtofunnyfilmsandcartoonsbeforemajormedicalproceduresareabletocopebetterwithpainandanxiety.__3__Theseareprofessionalclownswhoaresenttohospitalsandwardstoentertainanddistractsickchildren.Laughtertherapyhasbeeverypopularinrecentyearsandasaresult,moreandmorelaughterclubsarestartingtoopenupincitiesandtownsallovertheworld.Atalaughtersession,atrainedtherapistinstructsthegrouptoperformaseriesofex
