so-that的用法

so...that...如此……以致于……...sothat...以便于，为了“so...that...”句型的意思是“如此/这么……以致于……”，常引导结果状语从句，但“so...that...”是个爱“变脸”句型，你一不留意就会出错。“so...that...”句型及其转换也是中考的热点，现将其用法总结归纳如下，让我们一起来看看它是怎样变的吧。一、so...that...句型中的so是副词，常常用来修饰形容词或副词，常用句型为：主语+谓语+so+adj./adv.+that从句。例如：1.heissoyoungthatshecan'tlookafterherself.2.TheboyransofastthatIcouldn'tcatchhim.3.Hewassoangrythathecouldn'tsayaword.二、在“such...that...”句型中，such修饰名词，意思也是“如此……以致于……”但当名词前有many、much、(a)few、(a)little等词修饰时，句子中要用“so...that...”而不能用“such...that...”。例如：1.Hehassomuchmoneythathecanbuywhathewanted.2.I'vehadsomanyfallsthatIhavepainshereandthere.3.ThereislittlewaterintheglassthatIcan'tdrinkanymore.三、so与that也可连起来写，即变成：...sothat...(以便/为了……)，引导目的状语从句。例如：1.IgotupearlysothatIcouldcatchtheearlybus.2.Pleaseopenthewindowsothatwecanbreathefreshair.3.Youmustgonowsothatyouwon'tbelate.四、以“so...that”引导的结果状语从句可以转换成不定式的简单句，即可转换为“...enoughto...”或“...too...to”句型，但这种转换必须符合下列条件：1.当主句和从句的主语一致，且that从句是肯定句时，可用“enoughtodosth.”来转换。例如：Themanissostrongthathecanlifttheheavybox.→Themanisstrongenoughtolifttheheavybox.HewassocleverthathecanunderstandwhatIsiad.→HewascleverenoughtounderstandwhatIsiad.2.当主句和从句的主语不一致，且that从句是肯定句时，可以用“enoughforsb.todosth.”来替换，但须注意不定式的宾语要省略。例如：ThequestionissoeasythatIcanworkitout.→Thequestioniseasyenoughformetoworkout.Theboxissolightthathecancarryit.→Theboxislightenoughforhimtocarry.3.当主句和从句的主语一致，且that从句是否定句时，可以用“too...to”来替换。例如：Thegirlissoyoungthatshecan'tdressherself.→Thegirlistooyoungtodressherself.IwassotiredthatIcouldn'tgoonwiththework.→Iwastootiredtogoonwiththework.4.当主句和从句的主语不一致，且that从句是否定时，如果要用“too...to...”替换“so...that...”，则用介词for引出动词不定式的逻辑主语，可以用“too...forsb.todosth.”来替换，注意不定式的宾语要省略。Thebagissoheavythatshecan'tmoveit.→Thebagistooheavyforhertomove.Itissohotthatwecan'tsleep.→Itistoohotforustosleep.
