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。
(3)We have enough food for a month.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。
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。
(3)This room is large enough for us to sleep in.这个房间足够大,我们可以睡。
(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。)
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:
(1)Enough has been said on how to learn English well.关于如何学好英语已经说得足够多的了。
(2)I have enough to do today.今天我有足够多的事要做。
