couldn't = 不能,Can 和 Could的用法,情态动词增加了额外的意义主要动词.大多数情态动词多用.例如:Could I borrow your pen?(request) 这句意思有要求的情态,因为用Could.
found是过去式或过去分词,find解释是找寻,发现,寻获.

couldn't =could not 不能
found
v. 找到（find的过去分词）
vt. 创立，建立；创办

couldn't 是can't 的弱语气版本，礼貌一点
found 1. 如果作为谓语就是find（找到）的过去式
2. 如果作为被动的，be found 可以作为被找到（the apple is found.）或被建立（the building is found this year.）
