Enough作形容词

enough 用作形容词,意为“充足的,足够的”,在句中可作定语或表语。作定语时,它的位置较灵活,既可以放在它所修饰的名词前面,也可以放在被修饰名词的后面。例如:

I have enough money to buy a new computer.(=I have money enough to buy a new computer.)我有足夠的钱买台新电脑。

Enough作副词

enough用作副词 ,意为“充分地,足够地,十分,果然,确实”,要放在它所修饰的形容词、副词或动词的后面。例如:

He is brave enough to face dangers. 他很勇敢, 足以面对各种危险。

Enough作名词

enough用作名词,意为“足够,充分”。例如:

I have had enough. Thank you very much.我已经吃饱了,谢谢你。

【温馨提示】

1. enough不能与no 一起连用。如不可以说:I have no enough money to buy a car.应该说:I don’t have enough money to buy a car.

2. 用作形容词的enough不可以被very修饰,如不可以说:We have very enough time. 但可以用quite修饰,如可以说:We have quite enough time.

3. enough所修饰的形容词后面跟动词不定式的复合结构时,用介词for引起,而不用to。例如:

这本书很浅显,我足以读得懂。

误: This book is easy enough to me to read.

正: This book is easy enough for me to read.

4. can’t/can never...enough表示“越……越好,无论怎么……也不过分”。例如:

We can’t thank him enough. 我们无论怎么感谢他也不过分。

5. not...enough to  do 与enough...not to do 含义不同,前者否定enough前后两部分,后者只否定动词不定式。例如:

He was not old enough to drive a car. 他年龄不够大不能开车。

He was young enough not to drive a car.他年龄还小不能开车。
