  ①ample“充分的,富裕的”,意指绰绰有余。如:There is ample time,so you don’t have to hurry.时间很充裕,所以你不必这么匆匆忙忙的。②当只指数量时,用sufficient或enough较好,而不用adequate,因为 adequate还有“good enough适当的,足够好”的意思。试比较:The prisoners received adequate food(=good enough or enough in quantity).The prisoners received sufficient/enough food(=enough quantity).③enough“足够的”,用以修饰名词,可在名词之前或之后。它还可作副词:The room is big enough to hold a hundred people.这间房屋大得足以容纳一百人。④sufficient(足够的)和enough作形容词时意思一样,但比enough正式且不可用作副词。 Do you have sufficient books for the children? 你发给孩子们的书够了吗?
