句中sothat引导目的状语从句，从句中含有情态动词could。[用法总结](1)sothat引导目的状语从句，意为“以便，为了”，可用inorderthat替换，从句中常有may，can，could等情态动词。①Iwillleavesothatyoucanconcentrateonyourwork.我这就走，以便让你专心工作。②Hecameinquietlysothathewouldn’twakehiswifeup.他轻轻地进来，为了不把他的妻子吵醒。(2)sothat引导结果状语从句，意为“因此，所以”，通常不与情态动词连用，从句前可用逗号与主句隔开。③Igotupearly,sothatIcaughtthefirstbus.我起得很早，所以赶上了第一班公共汽车。④Suddenlyitbegantorainheavily，sothatitwasalmostimpossibletocarryondriving.突然下起了大雨，几乎无法继续开车。[名师提醒]

inorderthat也可以引导目的状语从句，常与sothat互换，sothat一般不用于句首，而inorderthat可用于句首。[巩固内化]完成句子/同义句转换①Wemuststudyharder_______________________________________________.为了早日实现我们的梦想，我们要更加努力地学习。②Theystartedoutearly,________________________________．他们早早就出发了，所以没误火车。③Heleftearlyinorderthathecouldavoidthetrafficjam.→Heleftearly___________hecouldavoidthetrafficjam.sothatwecouldrealizeourdreamsearliersothattheydidn’tmissthetrainsothat2.Totakeabicycle,youhadtoputinaspecialcard.(教材P37)要骑自行车，你必须放入一张特别的卡。[句式解读]

句中totakeabicycle为不定式短语作目的状语。[用法总结]动词不定式作目的状语通常译为“为了……”，主要有以下三种结构形式：①Theyworkedhardtogetgoodmarksinthefinalexams.为了在期终考试中得到好分数，他们很用功。②Theytookexerciseeverydaytokeephealthy.他们为了保持健康每天运动。③InordertolearnspokenEnglishwell,heoftentalkswithAmericanfriends.为了学好口语他常常和美国朋友交谈。④LilysawmanyChinesefilmssoastoknowmoreaboutChina.莉莉看了很多中国电影以便更多地了解中国。[巩固内化]单句语法填空/一句多译①Mr.Zhangdoeswhathecan____________(help)usimproveourEnglish.②我们将召开会议来讨论这种不健康的生活方式。We’llholdameeting________________theunhealthylifestyle.＝We’llholdameeting________________theunhealthylifestyle.＝We’llholdameeting________________theunhealthylifestyle.＝___________________theunhealthylifestyle,we’llholdameeting.tohelptodiscussinordertodiscusssoastodiscussTo/Inordertodiscuss名词用作动词一、在英文中，有许多“名词活用作动词”的现象。或者说，这些单词本身就有动词的意思，只是我们在学习这些单词的时候通常只接触了其名词的意思。举个最简单的例子“man”这个单词，我们都知道是人、男人的意思，但它也可以作动词，有操作、配置人员、使增强勇气、拿出男子气概等意思。Youneedtomanupandownuptoyourmistake.你要像个男人一样承认自己的错误。二、熟练掌握这种名词和动词之间的转换具有非常重要的意义，对于我们英语水平的提高也至关重要。它的主要作用体现在：1．让语言更加简洁比如说表示“我坐公共汽车去上班”这个意思，你可以说“Itakeabustowork”也可以说“Ibustowork”。当bus作动词时既包含了乘坐这个动作，又包含了所乘坐的交通工具，所以可以帮助省略不必要的take，让说话写作更加简洁明了。2．使语言更加生动比如corner这个单词，名词意思是角落、墙角，动词的意思则有转弯、垄断、使为难等等。Withthisnewtechnology,wearegoingtocornerthemarketwithinthenexttwoyears.有了
