中国人通常在屋子里挂灯笼过元宵(theLanternFestival)。自制纸灯笼只需要彩色硬纸、剪刀和胶水(constructionpaper,scissorsandglue)。首先，将一张长方形的(rectangular)纸对折，从对折线往开口处，每隔4厘米就剪开一直线。每次不要剪到底，留边约2厘米。然后打开硬纸，将纸卷成圆筒状(cylinder)，接着在两条短边上涂好胶水后把它们黏在一起。最后，剪下长12厘米、宽1厘米的一硬纸条做灯笼柄，并把剪好的纸条黏在灯笼上端的内沿上。ChinesepeoplealwayscelebratetheLanternFestivalbyhangingupChineselanternsinthehouse.Constructionpaper,scissorsandglueareallthingsyouneedforDIYofapaperlantern.First,foldarectangularpieceofpaperinhalf,andcutalongthefoldededgeevery4cm.Don’tcutallthewaytotheedgeofthepaper,leavingabout2cmatthetopofeachcut.Next,unfoldthepaper,androllitintoacylinder.Thenapplygluealongtheshortedgesandpressthepapertogether.Last,makethehandleofthelanternbycuttingastripofconstructionpaper12cmlongand1cmwide,andgluethestripcut-outtotheinsideedgesofthelantern’stopmargin.Unit

在中国，婚礼习俗各地不同，但也有共同点。在过去，举行婚礼前，新娘会由一位当地德高望重的老年妇女为她用彩色的棉绳扎头发。新娘要穿红裙子，因为中国人认为红色喜庆。新郎也要穿红褂子（beinredgown）。他们要拜（kowtow）天地，父母和夫妻对拜。在有的地方，婚礼的当晚亲戚朋友们会闹洞房（playgamesinthebridalchamber）。婚后的第三天，新婚夫妇要回新娘的娘家，和亲戚们聚餐。InChina,marriagecustomsdifferbyregions,buttherearesomethingincommon.Inthepast,beforetheweddingceremony,thebridewouldbehelpedbyarespectableoldwomantotieupherhairwithcolorfulcottonthreads.SheshouldweararedskirtasChinesebelievedredisthesymbolofdelight.Thebridegroomwasalsoinaredgown.Theyshouldkowtowtoworshiptheheaven,parentsandeachother.Onthenightoftheweddingday,therewasacustominsomeplaces—relativesorfriendsplayinggamesinthebridalchamber.Onthethirddayofthemarriage,thenewcouplewouldgobacktothebride’sparents’home.Theywouldbereceivedwithadinnerpartyincludingrelatives.Unit4A.Fillintheblankswiththewordsgivenbelow.Changetheformwherenecessary.Awomanhasa(an)__inherent__loveofbeauty.女人对美有一种内在的爱。2.Theyweretoldtotakewhateveractionthey__deemed____necessary.他们被告知采取任何他们认为必要的行动。3.Hepurposelytriedto__cultivate__goodrelationswiththepress.他有意与媒体建立良好的关系。4.Thepresentinternationalsituationremainstenseand_turbulent__.当前国际形势依然紧张动荡。5.Wecan’t_conceive___oflivingwithouttelephonesandcomputers.我们不能设想没有电话和电脑的生活。6.__Corrupt____judgeshavetakenmillionsofdollarsinbribes.腐败的法官收受了数百万美元的贿赂。7.What_prompted_______youtobuythatuglybutexpensivesuit

自去年11月以来，中国的通货膨胀持续上扬。据NBS（国家数据局NationalBureauofStatistics）表明，由于寒冬的影响，食品价格的上涨是推动一月份CPI上涨1.5%的主因。因为近年来人们的饮食和消费习惯发生了极大的改变，专家认为，为了更清晰实时地反映居民的生活总支出和经济压力的状况，CPI评估标准需要做出与实际情况相符的调整(modification)。由于房屋支出占收入的比重越来越大，因此相应的调整似乎是有必要，同时，政策的制定者要正确解读CPI及其他指标(metrics)以判断经济运行的状况(economicperformance)。China’sinflationhascontinuedtorisesinceNovemberlastyear.ItsCPIrose1.5percentinJanuary,mainlyboostedbyfoodpriceincreasesduetothecoldwinterweather,accordingtotheNBS(NationalBureauofStatistics).Sincepeople’seatingandconsumptionhabitshavechangedgreatlyinrecentyears,expertsheldthatthecriteriaforevaluatingCPIneededmodificationinlinewithactualconditionstogiveaclearerandreal-timepictureofthegenerallivingcostsandfinancialpressureofthecitizens.Housingcostsoccupyanincreasinglybiggershareofincomes,socorrespondingmodificationsseemtobenecessary,aspolicy-makerswillreadCPIandothermetricsforjudgingeconomicperformance.Unit6A.Fillintheblankswiththewordsgivenbelow.Changetheformwherenecessary.Today,publiccolleges__enroll____almostfifteenmillionstudents,whileprivatecollegesfewerthansixmillions.如今，公立大学招收了近1500万学生，而私立大学的学生不到600万。Obviouslyitis___exceedingly____hardtoprojectsevenortenyearsintothefuture.很显然，在未来的7到10年里，这是非常困难的。Hisstatementwasvery___vaguely__worded.他的声明措辞含糊。Ireceivedanencouraging___response___tomyadvertisement.我收到了一份鼓舞人心的广告。Thebarhasbecome__notorious___asameetingplacefordrugdealers.这个酒吧已经成为了臭名昭著的毒品交易者的聚会场所。Iheardsomeone___creeping____aroundthehouse.我听见有人在房子里爬来爬去。Itisunrealistictoput___undue___pressureonourselvesbysayingwearethebest.说我们是最好的是给自己施加过多的压力，这种做法不切实际。8.Itis__indisputable_thatthecrimeratehasbeenrising.犯罪率一直在上升是无可争辩的。B.Fillintheblankswiththeexpressionsgivenbelow.Changetheformwherenecessary.Thesniper’sfootstepvoice__rangout________.狙击手的脚步声响起。Studentswereeducatedonhowto___keepsafe__fromdangerorattack.学生们接受了如何避免危险或攻击的教育。He__sneeredat________peoplewholikedpopmusic.他嘲笑喜欢流行音乐的人。PekingUniversity____provided___her__with___anallowancewhenshewasstudyingthere.当她在那里学习时，北京大学给她提供了零用钱。Wemust___engagewith___allofourpartnersonthisimportantissue.在这个重要问题上，我们必须与我们所有的合作伙伴进行接触。6.Themovie____transformed____heralmostovernightfromanunknownschoolgirl___into__astar.这部电影一夜之间几乎把她从一个无名小女孩变成了明星。1.这个公司因为生产劣质产品而臭名昭著｡(benotoriousfor)Thecompanyisnotoriousforproducingdefectiveproducts.2.政府方面对他的评论一直没有反应｡(response)Therehasbeennoresponsetohisremarksfromthegovernment.3.最好不要过分看重他的批评｡(undue)Itwouldbewisenottogiveundueimportancetohiscriticisms.4.许多父母为他们的孩子注册就读私立学校｡(enroll)Manyparentsenrolledtheirchildreninprivateschools.5.挑战在于将这一知识转变为行动｡(transforminto)Thechallengeistotransformthisknowledgeintoaction.胡同在蒙古语中是指水井的意思。胡同宽约9米,最初起源于元朝(1271—1368),是用于给小巷或小街的命名。现在胡同已经成为北京文化的代表,吸引了越来越多的中外游客。以前的北京是由无数的庭院围绕着紫禁城组成,胡同向四面八方延伸,把各种各样的院子连接在一起。胡同有各自的布局结构,从空中向下看时,就像一个巨大的棋盘。这些胡同是北京发展的见证。HutongisaMongolianwordmeaningwaterwell.Atninemeterswide,itisthenamegiventoalaneorsmallstreetthatoriginatedduringtheYuanDynasty(1271—1368).NowtheyhavebecometherepresentativeofBeijing’sculture,attractingmoreandmoretouristsfromhomeandabroad.Inthepast,BeijingwascomposedofhundredsofcourtyardsaroundtheForbiddenCity,andtheselanesstretchedoutinallfourdirections,connectingthedifferentkindsofcourtyardsinthecity.Thelaneshavetheirownlayoutsandstructureswhichviewedfromtheair,resemblingachessboard.AndtheselaneshavewitnessedthedevelopmentofBeijing.
