句中sothat引導(dǎo)目的狀語從句，從句中含有情態(tài)動詞could。[用法總結(jié)](1)sothat引導(dǎo)目的狀語從句，意為“以便，為了”，可用inorderthat替換，從句中常有may，can，could等情態(tài)動詞。①Iwillleavesothatyoucanconcentrateonyourwork.我這就走，以便讓你專心工作。②Hecameinquietlysothathewouldn’twakehiswifeup.他輕輕地進(jìn)來，為了不把他的妻子吵醒。(2)sothat引導(dǎo)結(jié)果狀語從句，意為“因此，所以”，通常不與情態(tài)動詞連用，從句前可用逗號與主句隔開。③Igotupearly,sothatIcaughtthefirstbus.我起得很早，所以趕上了第一班公共汽車。④Suddenlyitbegantorainheavily，sothatitwasalmostimpossibletocarryondriving.突然下起了大雨，幾乎無法繼續(xù)開車。[名師提醒]

inorderthat也可以引導(dǎo)目的狀語從句，常與sothat互換，sothat一般不用于句首，而inorderthat可用于句首。[鞏固內(nèi)化]完成句子/同義句轉(zhuǎn)換①Wemuststudyharder_______________________________________________.為了早日實(shí)現(xiàn)我們的夢想，我們要更加努力地學(xué)習(xí)。②Theystartedoutearly,________________________________．他們早早就出發(fā)了，所以沒誤火車。③Heleftearlyinorderthathecouldavoidthetrafficjam.→Heleftearly___________hecouldavoidthetrafficjam.sothatwecouldrealizeourdreamsearliersothattheydidn’tmissthetrainsothat2.Totakeabicycle,youhadtoputinaspecialcard.(教材P37)要騎自行車，你必須放入一張?zhí)貏e的卡。[句式解讀]

句中totakeabicycle為不定式短語作目的狀語。[用法總結(jié)]動詞不定式作目的狀語通常譯為“為了……”，主要有以下三種結(jié)構(gòu)形式：①Theyworkedhardtogetgoodmarksinthefinalexams.為了在期終考試中得到好分?jǐn)?shù)，他們很用功。②Theytookexerciseeverydaytokeephealthy.他們?yōu)榱吮３纸】得刻爝\(yùn)動。③InordertolearnspokenEnglishwell,heoftentalkswithAmericanfriends.為了學(xué)好口語他常常和美國朋友交談。④LilysawmanyChinesefilmssoastoknowmoreaboutChina.莉莉看了很多中國電影以便更多地了解中國。[鞏固內(nèi)化]單句語法填空/一句多譯①M(fèi)r.Zhangdoeswhathecan____________(help)usimproveourEnglish.②我們將召開會議來討論這種不健康的生活方式。We’llholdameeting________________theunhealthylifestyle.＝We’llholdameeting________________theunhealthylifestyle.＝We’llholdameeting________________theunhealthylifestyle.＝___________________theunhealthylifestyle,we’llholdameeting.tohelptodiscussinordertodiscusssoastodiscussTo/Inordertodiscuss名詞用作動詞一、在英文中，有許多“名詞活用作動詞”的現(xiàn)象?；蛘哒f，這些單詞本身就有動詞的意思，只是我們在學(xué)習(xí)這些單詞的時候通常只接觸了其名詞的意思。舉個最簡單的例子“man”這個單詞，我們都知道是人、男人的意思，但它也可以作動詞，有操作、配置人員、使增強(qiáng)勇氣、拿出男子氣概等意思。Youneedtomanupandownuptoyourmistake.你要像個男人一樣承認(rèn)自己的錯誤。二、熟練掌握這種名詞和動詞之間的轉(zhuǎn)換具有非常重要的意義，對于我們英語水平的提高也至關(guān)重要。它的主要作用體現(xiàn)在：1．讓語言更加簡潔比如說表示“我坐公共汽車去上班”這個意思，你可以說“Itakeabustowork”也可以說“Ibustowork”。當(dāng)bus作動詞時既包含了乘坐這個動作，又包含了所乘坐的交通工具，所以可以幫助省略不必要的take，讓說話寫作更加簡潔明了。2．使語言更加生動比如corner這個單詞，名詞意思是角落、墻角，動詞的意思則有轉(zhuǎn)彎、壟斷、使為難等等。Withthisnewtechnology,wearegoingtocornerthemarketwithinthenexttwoyears.有了
