在英語中,Enough一詞使用頻率之高是人人皆知的,它的基本意思是“充分的,足夠的,充分的”,它既可作形容詞、副詞用,也可作代詞用。下面小編就來詳細介紹下 enough的用法說明,希望對大家有用。 enough的用法說明如下: 一、作形容詞 Ⅰ、 作定語時,既可修飾可數名詞,也可修飾不可數名詞。 (1) Are there enough seats for ten persons? 有沒有足夠十人的座位? (2)We have enough food for a week. 我們有足夠維持一週的食物。 Ⅱ、 作表語 只有當主語是代詞數詞和“數詞+名詞”時,enough才可作表語用,如果主語是名詞,enough便不能作表語用了,如: (1) That’s enough.. Thank you. 夠了,謝謝。 (2) Five is enough. 五個夠了。 (3) Will 12 apples be enough? 十二個蘋果夠不夠? 如果enough之後跟其它修飾語(如不定式或for短語時),前面的主語不受限制。如: (1)The time is enough to finish it.(=There is enough time to finish it) 有足夠的時間完成這一工作。 (2)The food is enough for us two.(=There is enough food for us two) 有足夠我們倆吃的食物。 二、 作代詞,充當主語、賓語. (1)Enough has been said on this subject 關於這個問題說得已經夠多的了。 (2)-Do you need some more materials? 你們還需要材料? -No, thanks. Enough have been supplied for us. 不要了,謝謝!我們已經夠了。 (3)I have enough to do today. 今天我有足夠多的事要做。 三、 作副詞 修飾形容詞和副詞,且必須放在它們之後,如: (1)This room is large enough for us to sleep in.這個房間足夠大,我們可以睡.(不可說enough large) (2) He knows the situation well enough.對他情況瞭解得非常清楚。(不可說enough well”) 四、 當enough和另一形容詞同時修飾一個名詞時,有兩種不同的位置。 Ⅰ、enough放在形容詞之後,此時,enough修飾形容詞時,結構為“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 (3) I don’t have big enough nails to mend the cupboard.我沒有足夠大的釘子修理櫃子。 Ⅱ、enough放在形容詞之前,此時,enough修飾名詞,結構為“enough+adj.+名詞 ”,表示“足夠多的…”,如: (1) enough large room 足夠大的房間 (2) enough deep well 足夠深的井 (3)I don’t have enough big nails to mend the cupboard. 我沒有足夠大的釘子修理櫃子。 五、 與介詞of構成短語enough of,使用時,須遵守如下規律: 1、enough of+既定詞+名詞(其中既定詞為冠詞,物主代詞或指示代詞) 2、enough of+代詞 (1)Is there enough of the blue material?(=Is there enough blue material? 有足夠的藍色料子嗎? (2)I’ve had enough of your complaints.(=I’ve had enough complaints from you) 你的抱怨我已經聽夠了。 六、 enough之後跟介詞短語”for sb”和不定式 “for sb to do sth”, 如: (1)He was lucky enough to succeed in his first attempt.他夠幸運的了,第一次嘗試就成功了。 (2)He spoke slowly enough for everyone to understand.他說話慢得每個人都能聽懂。 (3)There isn’t enough ice cream for all the children.冰淇淋不夠分給所有的小孩。 七、 enough不能與no構成否定句,只能藉助not以及其他否定詞,如: (1)We have not enough glasses for everyone.(不能說成no enough glasses.我們的杯子不夠分給每個人。 (2)We had hardly enough food to go around at the picnic.(不能說成no enough food.我們的食物剛夠分給參加野餐的人。
