Enough作形容詞
enough 用作形容詞,意為“充足的,足夠的”,在句中可作定語或表語。作定語時,它的位置較靈活,既可以放在它所修飾的名詞前面,也可以放在被修飾名詞的后面。例如:
I have enough money to buy a new computer.(=I have money enough to buy a new computer.)我有足夠的錢買臺新電腦。
Enough作副詞
enough用作副詞 ,意為“充分地,足夠地,十分,果然,確實”,要放在它所修飾的形容詞、副詞或動詞的后面。例如:
He is brave enough to face dangers. 他很勇敢, 足以面對各種危險。
Enough作名詞
enough用作名詞,意為“足夠,充分”。例如:
I have had enough. Thank you very much.我已經(jīng)吃飽了,謝謝你。
【溫馨提示】
1. enough不能與no 一起連用。如不可以說:I have no enough money to buy a car.應該說:I don’t have enough money to buy a car.
2. 用作形容詞的enough不可以被very修飾,如不可以說:We have very enough time. 但可以用quite修飾,如可以說:We have quite enough time.
3. enough所修飾的形容詞后面跟動詞不定式的復合結(jié)構(gòu)時,用介詞for引起,而不用to。例如:
這本書很淺顯,我足以讀得懂。
誤: 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,無論怎么……也不過分”。例如:
We can’t thank him enough. 我們無論怎么感謝他也不過分。
5. not...enough to ?do 與enough...not to do 含義不同,前者否定enough前后兩部分,后者只否定動詞不定式。例如:
He was not old enough to drive a car. 他年齡不夠大不能開車。
He was young enough not to drive a car.他年齡還小不能開車。
