不行
He is too old to join the army.
1、too..to...是太.所以不能.表示否定
比如：He is too short to reach the apple.他太矮了所以够不到苹果
2、so..that..是太.所以.表示肯定
比如：He is so handsome that many girls love him.他太帅了所以很多女孩子爱他
如果要表示too..to..就要用否定词
比如：He is so short that he cannot reach the apple.这句意思和1一样,但是用了cannot这个否定词~如果用too..to就不用~
