从几道中考题谈so… that, too…to和enough to
之间的相互转换
江苏 李勇
so…that, too…to和enough to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. He is old enough to go to school.
He is __________ __________ that __________ __________ go to school.
2. She was so weak that she couldn’t take care of her baby.
She was __________ weak __________ take care of her baby.
(答案:1. so old; he can 2. 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…
for sb to结构。例如:
She is so young that she can’t go to school. ,She is too young to go to school.
The box is so heavy that he can’t carry it. ,The box is too heavy for him to carry.
二、so…that与enough to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enough to结构;若从句主语与主句主语不相同时，so…that可转换为
enough for sb to结构。例如:
Xiao Lin is so old that he can go to school. ,Xiao Lin is old enough to go to school.
The box is so light that he can carry it. ,The box is light enough for him to carry.
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enough to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enough for sb to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:
The man is so old that he can’t go to work. ,The man isn’t young enough to go to work.
The desk is so heavy that I can’t move it. ,The desk isn’t light enough for me to move.
三、enough to的句式为否定式时，enough to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:
He is not old enough to do the work. ,He is too young to do the work.
The problem is too difficult for me to work out. , The problem isn’t easy
enough for me to work out.
改写同义句，每空一词。
1. The book is interesting enough for everybody to read.
The book is __________ interesting __________ everybody likes to read it.
2. The boy is so short that he can’t reach the buttons of the lift.
The boy is __________ short __________ __________ the buttons of the lift.
The boy isn’t __________ __________ __________ __________ the buttons of the lift.
答案:
1. so; that
2. too; to reach; tall enough to reach
