adequate, ample, enough, sufficient
这组词都有“足够的”意思。它们的区别在于：
1.enough为一般用语,有时可与adequate互换。enough常用来表示数量或程度,不宜用于表示性质、质量; 而adequate既可用于描述数量或程度,也可用于描述性质、质量。
2.adequate表示“仅够满足”“恰好满足”; enough和sufficient还可表示足够满足; 而ample表示充足而有余,即ample>sufficient>enough>adequate。
3.sufficient与enough同义,确切程度比 enough 大,前者多用于需要的满足,后者则多用于欲望的满足; 前者多用于书面语,后者多用于口语。
