enough的语法怎样区分
enough一词在英语中既可放在被修饰的词之前,又可放在被修饰的词之后.因此很多同学觉得enough 很难理解.其实这涉及到enough的词性问题.请看下面几个例句：
1.He is not old enough to go to school.他年龄太小,不能去上学.
2.But there were not enough people to pick them.但是没有足够的人采摘它们.
3.Six bottles of wine will be enough.六瓶葡萄酒就够了.
要想搞清楚上面3个句子中enough的词性及含义,得先掌握它的用法规律.
[一号档案] enough作副词用时,意为“充分地；足够地”,通常要把它放在所修饰的形容词、副词或动词的后面,常与不定式或介词for连用.如：
1.You don't practise enough at the piano.你钢琴弹奏练习得不够.
2.Is the river deep enough for swimming?河水够深来游泳吗?
[二号档案] enough作形容词,意为“充足的；足够的”,在句中可作定语或表语.作定语时,一般放在它所修饰的名词前面.如：
1.I have enough money to buy a colour TV set.我有足够的钱买台彩电.
2.Fifteen minutes is enough time for you to have a coffee.15分钟够你喝杯咖啡了.
[三号档案] enough也可作代词用,意为“充分;足够”.如：
I have had enough,thank you.我吃饱了.
看了以上有关enough的用法档案,同学们不难发现：在例句1中,enough是副词,作状语,用来修饰形容词old；而在句2中,enough是形容词,作定语,修饰名词people;句3中enough 是代词.
