ttodo。毕业后,她在职业生涯中到了一个必须决定做什么的时间点。（3）先行词与定语从句被谓语分隔。此时,先行词通常是句子的主语,因定语从句较长,主句谓语较短,为使句子结构平衡,常将定语从句移至谓语之后。Theprofessorenteredthehallwhohadjustpresentedseverallectures.刚刚做完几场演讲的教授进了大厅。ThedaysaregonewhenweChinesewerebulliedbytheinvaders.我们中国人受侵略者欺负的日子一去不复返了。练习：用“介词+关系代词”填空1.Haveyoueverreadthebook______________therearemanypictures?2.Theman______________hehadatalkyesterdayisadoctor.3.Thelibrary______________weoftenborrowbooksisverylarge.4.Thegentleman______________youspokejustnowisourheadmaster.5.Thisisthenewbicycle______________Ispentfivehundreddollars.6.Givemeapieceofpaper______________Icanwritethephonenumber.7.Theboybuiltatelescope______________hecouldstudytheskies.8.Ericreceivedtraininginputerforoneyear,______________hefoundajobinabigpany.9.Herearethetabletennisplayers,some______________arefromourschool.10.Thetool______________heisworkingiscalledanengine.(Answers:1.inwhich2.withwhom3.fromwhich4.to/withwhom5.onwhich6.onwhich7.throughwhich8.afterwhich9.ofwhom10.withwhich)4.学生活动：完成练习。DiscussingroupsandpleteActivity2inpage65.(Answers:1.TheZhuangisanethnicgroupofwhichthepopulationisthelargestofallethnicgroupsinChina.2.GuangxiisaprovinceinwhichtheLongjiRiceTerracesarelocated.3.IwanttovisitthisculturallandscapetowhichthetitleofUNESCOWorldHeritageSitewasgivenin2016.4.HeisanexpertonriceplantingfromwhomthelocalZhuangpeoplehavelearntalot.)5.学生活动：完成练习。pletethepassagewithapreposition+whom/which.(Answers:1.fromwhich2.inwhich3.forwhich4.forwhom)三、Afterclass用适当的关系代词、关系副词或“介词+关系代词”完成下列各句1.Mymotherfoundasheetofpaper______________shewantedtowrapthatpackofcandies.2.Sandstormsoftenhitthisregion,______thereforehasmadethesoiltherebeedesert.3.Expertsinagriculturesaychemicalfertilizers______enablecropstogrowfastermayharmthesoil.4.Thepanyhasdesigneda
