enough的用法总结：
一、enough作形容词用法
enough作形容词时，意思是“充足的”、“足够的”，后面常跟for引导的短语或可数名词。
1、作定语。
修饰不可数名词或可数名词复数，位置可前可后，例如：
(1)Are there enough seats for four persons?
有没有足够四个人的座位?
(2)We have enough time/time enough to get to the station.
我们有足够的时间赶到车站。

我们有足够维持一个月的食物。
2、作表语。例如：
(1)Six chairs should be enough.
六把椅子应该足够了。
(2)That’s enough.Thank you.
够了，谢谢。
二、enough作副词用法
enough作副词时，意为“充足地”、“足够地”，可用来修饰形容词和副词，且必须放在它们之后，例如：
(1)I was foolish enough to believe her.
我相信了她，真是太傻了。
(2)He knows the situation well enough.
对他情况了解得非常清楚。(不可说enough well”)
(3)This room is large enough for us to sleep in.
这个房间足够大，我们可以睡.(不可说enough large)
(4)He has eaten enough.
他已经饱了。(enough还可以修饰副词和动词，但必须后置。)
三、enough作代词用法
enough作代词时，意为“足够”、“充足”，充当主语、宾语.当其作主语时，看作单数。例如：

(2)I have enough to do today.
今天我有足够多的事要做。
四、 当enough和另一形容词同时修饰一个名词时，有两种不同的位置。

(1) a large enough room一间足够大的房间
(2) a deep enough well 一口足够深的井
