语法现象非限制性定语从句结构特点从句与主句之间有逗号隔开，独立存在，起补充说明的作用。句式演变关系词不能由that引导；而“介词+关系代词或关系副词”均可引导非限制性定语从句【典例示范】Manylessonsarenowavailableonline，fromwhichstudentscanchooseforfree.许多课程现在都可以在网上找到，学生们可以从中免费选择。DrRowan，whosesecretaryresignedtwoweeksago，hashadtodoallhisowntyping.罗文博士的秘书两周前辞职了。他现在只能自己打字。【即学即练】单句语法填空/完成句子(1)Then，anOICrepresentativegaveussomedetails，_________somewhatinterestedme.(2)Thereisagreatdealofoxygenaroundus，without_________wecannotlive.(3)Aftergraduation，IdecidedtostayinChongqing，_________Ispentmychildhood.(4)这位孤独的老人渴望养一只宠物，这样能够陪伴着她。Thelonelyoldladywaseagertokeepapet，_________________________________.whichwhichwherewhichcouldkeephercompany2.(教材P27)Inrecentyears，ChinahasjoinedothernationsonseveralexpeditionstoexploretheArctic.

近年来，中国与其他国家一起进行了几次北极探险。【句式提炼】本句中的“inrecentyears”是现在完成时的标志。现在完成时的基本结构为：have/hasdone。【归纳拓展】
