too..to能用什么代替

so...that...;such...that...。

1、too...to...:She is too fat to run.

2、so...that...:She is so fat that can't run.

3、such...that...:She is such a fat girl that can't run.

三个句子意思一样:她太胖了以至于跑不起来。

too...to结构不表示否定意义:

1、如果too后的形容词是anxious,apt,easy,eager,kind,glad,ready,willing,delighted等,?too相当于very, extremely, particularly(很,大,非常),动词不定式不与too呼应而是修饰形容词,因而表示肯定意义。

2、too前有only,but,all等词时,便没有否定的意思。

3、too前如有not, never的too...to结构不表示否定意义, not, never否定谓语动词,构成双重否定,因而表示肯定意义,意思是“并不(太)…所以能…”。
