［中考点击］从几道中考题谈so…that,too…to和enoughto之间的相互转换江苏李勇so…that,too…to和enoughto都是初中英语教材中的重要结构，在一定条件下它们可以相互转换，并经常成为中考考查的热点之一。先请看下面两道中考试题1.Heisoldenoughtogotoschool.Heis____________________that____________________gotoschool.2.Shewassoweakthatshecouldn’ttakecareofherbaby.Shewas__________weak__________takecareofherbaby.（答案：1.soold;hecan2.too;to）那么在什么情况下三者可以相互转换呢？一、so…that与too…to的转换当that引导的从句为否定式且从句主语与主句的主语相同时，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…forsbto结构。例如：Sheissoyoungthatshecan’tgotoschool.＝Sheistooyoungtogotoschool.Theboxissoheavythathecan’tcarryit.＝Theboxistooheavyforhimtocarry.二、so…that与enoughto的转换1.当that引导的从句为肯定式时，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enoughforsbto结构。例如：XiaoLinissooldthathecangotoschool.＝XiaoLinisoldenoughtogotoschool.Theboxissolightthathecancarryit.＝Theboxislightenoughforhimtocarry.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enoughforsbto的否定结构。同时要注意，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：Heisnotoldenoughtodothework.＝Heistooyoungtodothework.Theproblemistoodifficultformetoworkout.＝Theproblemisn’teasyenoughformetoworkout.改写同义句，每空一词。1.Thebookisinterestingenoughforeverybodytoread.Thebookis__________interesting__________everybodylikestoreadit.2.Theboyissoshortthathecan’treachthebuttonsofthelift.Theboyis__________short____________________thebuttonsofthelift.Theboyisn’t________________________________________thebuttonsofthelift.答案：1.so;that2.too;toreach;tallenoughtoreach
