1、enough的用法一、作形容词Ⅰ、 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。Ⅱ、 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 app
2、les 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
