Enough 用法聚焦


(安徽濉溪 丁红艳)

enough是个兼类词,它可以用作形容词、副词或名词。
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。例如:

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。

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。
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。例如:

That's enough. 这就够了。

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.
这个男孩到上学的年龄了。
I know him well enough. 我非常了解他。
He didn't get up early enough to catch the early bus. 他起床不够早,没有赶上早班车。

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。例如:

She sings well enough.= She sings very well.
她唱得相当好。

3. enough 可用于“It's ... enough for ... to do sth.”结构中,也可以用于“It's ... enough that ...”这种句子结构中。例如:

It isn't low enough for me to touch.
那不够低,我摸不着。

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。例如:

Enough is as good as feast. 知足者常乐。
I've had enough, thank you.
我已经吃够了,谢谢你。

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.
应说:I don't have enough money to buy a car.

2. enough用作形容词时不可被very修饰,但可以用quite修饰。例如:

We have quite enough time.
我们有足够的时间。

3. can't / can never ... enough表示“越……越好;无论怎样……也不过分”。例如:

You can never be careful enough.
你越细心越好。
We can't thank him enough.
我们无论怎样感谢他也不过分。
