enough的用法
1、 作形容词
1.作定语时,既可修饰可数名词,也可修饰不可数名词。
(1) Are there enough seats for ten persons? 有没有足够十人的座位?
(2)We have enough food for a week. 我们有足够维持一周的食物。
2.作表语
只有当主语是代词数词和“数词+名词”时,enough才可作表语用,如果主语是名词,enough便不能作表语用了,如:
(1) That’s enough.Thank you. 够了,谢谢。
(2) Five is enough. 五个够了。
(3) Will 12 apples be enough? 十二个苹果够不够?
如果enough之后跟其它修饰语(如不定式或for短语时),前面的主语不受限制。如:
(1)The time is enough to finish it.(=There is enough time to finish it) 有足够的时间完成这一工作。
(2)The food is enough for us two.(=There is enough food for us two)有足够我们俩吃的食物。
二、 作代词,充当主语、宾语.
(1)Enough has been said on this subject 关于这个问题说得已经够多的了。
(2)----Do you need some more materials? 你们还需要材料?
----No,thanks.Enough have been supplied for us. 不要了,谢谢!我们已经够了。

(1)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)
(2) He knows the situation well enough.对他情况了解得非常清楚。(不可说enough well”)
