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.
