當(dāng)enough后的名詞前有冠詞、形容詞性物主代詞、指示代詞或其本身就是代詞時(shí),要用介詞of。
enough的用法
一、enough作形容詞用法
enough作形容詞時(shí),意思是“充足的”、“足夠的”,后面常跟for引導(dǎo)的短語或可數(shù)名詞。
1、作定語
修飾不可數(shù)名詞或可數(shù)名詞復(fù)數(shù),位置可前可后,例如:
(1)Are there enough seats for four persons?
有沒有足夠四個(gè)人的座位?
(2)We have enough time/time enough to get to the station.
我們有足夠的時(shí)間趕到車站。
(3) We have enough food for a month.
我們有足夠維持一個(gè)月的食物。
2、作表語
例如:
(1)Six chairs should be enough.
六把椅子應(yīng)該足夠了。
(2)That’s enough.Thank you.
夠了,謝謝。
二、enough作副詞用法
enough作副詞時(shí),意為“充足地”、“足夠地”,可用來修飾形容詞和副詞,且必須放在它們之后,例如:
(1)I was foolish enough to believe her.
我相信了她,真是太傻了。
(2)He knows the situation well enough.
對(duì)他情況了解得非常清楚。(不可說enoug hwell)
(3)This room is large enough for us to sleep in.
這個(gè)房間足夠大,我們可以睡.(不可說enough large)
(4)He has eaten enough.
他已經(jīng)飽了。(enough還可以修飾副詞和動(dòng)詞,但必須后置。)
三、enough作代詞用法
enough作代詞時(shí),意為“足夠”、“充足”,充當(dāng)主語、賓語.當(dāng)其作主語時(shí),看作單數(shù)。例如:
(1)Enough has been said on how to learn English well.
關(guān)于如何學(xué)好英語已經(jīng)說得足夠多的了。
(2)I have enough to do today.
今天我有足夠多的事要做。
四、當(dāng)enough和另一形容詞同時(shí)修飾一個(gè)名詞時(shí),有兩種不同的位置
enough放在形容詞之后,此時(shí),enough修飾形容詞時(shí),結(jié)構(gòu)為“adj.+enough+名詞”,表示“足夠…的…”,如:
(1) a large enough room.一間足夠大的房間
(2)a deep enough well.一口足夠深的井
