题目

请把以下词组造句
SO.that
enough.to
too.to
再把以下的词组的用法说出来
SO......that
enough......to
too......to
各造2个句子

答案

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.
