表达结果的句型在初中英语中,表达结果的so．．．that，too．．．to和enoughto句式是比较重要的结构。在一定条件下它们可以相互转换，并经常成为中考热点1．Thewaterwassodirtythatwecouldn'tdrinkit．Thewaterwas____dirtyforus____drink．2．Thechildissoyoungthathecan'tputonhisclothes．Thechildisn't____________putonhisclothes．3．Theproblemistoodifficultformetoworkout．Theproblemisn't________formetoworkout．Theproblemis____difficult_____I____workitout.然而,三者的转换是有着一定的条件与规则的:一、so．．．that与too．．．to的转换当that引导的从句为否定式，若从句主语与主语的主语相同时，so．．．that可转换为too．．．to结构；若从句主语与主句的主语不相同时，so．．．that可转换为too．．．forsb．to结构。例如：Heissoyoungthathecan'tgotoschool．→Heistooyoungtogotoschool．Theboxissoheavythathecan'tliftit．→Theboxistooheavyforhimtolift．二、so．．．that与enoughto的转换1．当that引导的从句为肯定式，若从句主语与主句主语相同时，so．．．that可转换为enoughto结构；若从句主语与主句主语不相同时，so．．．that可转换为enoughforsb．to结构。例如：Tomissooldthathecangotoschool．→Tomisoldenoughtogotoschool．Theboxissolightthatthechildcanliftit．→Theboxislightenoughforthechildtolift．2．当that引导的从句为否定式时，若从句主语与主句主语相同时，so．．．that可转换为enoughto的否定结构；若从句主语与主句主语不相同时，so．．．that可转换为enoughforsb．to的否定结构。注意：转换后的形容词（副词）要用其相应的反义词。例如：Themanissooldthathecan'tgotowork．→Themanisn'tyoungenoughtogotowork．ThedeskissoheavythatIcan'tmoveit．→Thedeskisn'tlightenoughformetomove．三、enoughto的句式为否定式时，enoughto可以转换为too．．．to结构。但转换后的too．．．to结构中的形容词（副词）要用其相应的反义词。例如：Heisnotoldenoughtodothejob．→Heistooyoungtodothejob．Tomdidn'twalkslowlyenoughforustokeepupwith．→Tomwalkedtoofastforustokeepupwith．
