3) 从某事物中得到无穷无尽的好处，受用不尽。

4) 对某一喜爱的事物尽情享用。

有时也可以省略 of it。

5) 老是反复某一观点或某一故事。

此外，动词的进行时态被否定，后面加上 enough，此时否定的意义变为肯定，表示“没完没了地做某事”。

• We're not getting a big enough jolt from our coffee, sodas and energy drinks these days. (Reader's Digest, Oct. 2007, p.24)这些日子，我们老是拿我们的咖啡、苏打水和能量饮料来提神。

如果不是否定，而是肯定的 have enough of something（第四类或第三类动词），那么意思就是“尝够了…的滋味”、“对…领教够了”。
