enough是个兼类词,它既可以用作形容词和副词,也可以用作名词。
一、enough作形容词用时,意思是“足够的;充分的”,通常用于修饰名词。enough修饰名词时一般趋向于放在所修饰的名词前,也可以放在后面,但现代英语中不常用。如:
We have enough time to do our homework. 我们有充足的时间做家庭作业。
There is room enough for 30 people to live here. 这儿有足够30人住的地方。
Are there enough seats? 座位够吗?
enough置于所修饰的名词之后,句意和语气不如enough置于名词前时强烈。
当enough用于系动词be之后时,如果单独作表语,那么主语多为代词that或it,即
enough在这种情况下不宜用于主语为名词的句子里。如:
Thats enough. 够了。
二、enough作副词用时,有“足够地,充分地;相当地,还可以”等意思。
1. enough修饰形容词、副词或动词时应放在被修饰词的后面,通常表示程度,意思为“足够地;充分地”。例如:
The boy is old enough to go to school. 这孩子到上学的年龄了。
I know him well enough. 我非常了解他。
He didnt get up early enough to catch the early bus. 他起床不够早,没有赶上早班车。
Is this good enough? 这个够好吗?
2. enough表示“相当地;还可以”,用来修饰形容词、副词,相当于very, quite等。如:
She sings well enough. = She sings very well. 她唱得相当好。
3. enough可用于“Its... enough for... to do sth.”结构,也可以用于“Its... enough that...”这种句子结构中。如:
This room is big enough for me to live in. 我一个人住这个房间够大了。
It isnt low enough for me to touch. 那不够低,我摸不着。
He is strong enough to carry the box. 他很强壮,能举起这只箱子。
三、enough作名词时,意思是“足够(的数量或数目)”,可以作主语和宾语。如:
Enough is as good as feast. 知足者常乐。
Ive had enough, thank you. 我已经吃够了,谢谢你。
我们在使用enough时,还需要注意以下几点:
1. enough不能与no连用。例如:不可以说I have no enough money to buy a car. 而应说: I dont have enough money to buy a car.
2. enough用作形容词时不可用very修饰,但可以用quite修饰。如:
We have quite enough time. 我们有十分充足的时间。
3. cant / can never... enough表示“越……越好;无论怎样……也不过分”。如:
You can never be careful enough. 你越细心越好。
We cant thank him enough. 我们无论怎样感谢他也不过分。endprint
