sufficient， adequate， enough
enough,sufficient,adequate这三个词都表示“足够的”或“充分的”。其中只有enough可以用作副词或名词，含义仍为“足够的”。
enough和sufficient在含义上几乎没有差异，只是enough的用法较多，这两个词都表示“完全满足需要，而且既不多余，也不缺少”。
adequate虽然也表示“足够的”、“充分的”，但是和另二词之间有着比较明显的细微差异，因为这个词的内涵是：对于必不可少的东西在数量上应当是合理的、公平的或不苛刻的。Five men will be quite enough (or sufficient).这句话说的是：5个人就十分充足了， 再多给一个人就没有必要了His wages are adequate to support three people. 这句话说的是：他的工资够养活3个人的。即这些钱养活3个人够得上一般生活水平，并不苛刻。可见其差异非常细微。词义差别越细微，表意越准确。例如：“我为他干了3小时的活，他付给我20英镑。我觉得那20英镑的工钱是足够了的”。这两句话在英译时，其中的“足够的”必须用adequate，因为这里说的“足够”包含了“公平、合理”的意思。故这两句可译为：I worked for him three hours, and he paid me 20 pounds. I think the 20 pounds are adequate for my work. 此外， 应注意下面例句中enough的各种用法
