The teacher speaks so fast that I can't catch the word.（不能理解） My brother walks so slowly that he can't catch up with me. (赶不上)

He ran so quickly that no one could catch up with him. 他跑得非常快，没人能赶上他。 注意：在一定条件下“so …that…”句型可以和enough to和too…to…句型转换。 (1) so．．．that与too．．．to的转换

当that引导的从句为否定式时，若从句主语与主语的主语相同，so… that可转换为too…to结构；若从句主语与主句的主语不相同，so…that可转换为too…for sb．to结构。例如： He is so young that he can't go to school．→ He is too young to go to school． The box is so heavy that he can't lift it．→The box is too heavy for him to lift． (2) 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： Tom is so old that he can go to school．→Tom is old enough to go to school．

The box is so light that the child can lift it．→The box is light enough for the child to lift． 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，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，so…that可转换为 enough for sb. 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：

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．

(3) 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 job．→He is too young to do the job．

Tom didn't walk slowly enough for us to keep up with him．→Tom walked too fast for us to keep up with him．
