enough的用法
一、enough可以作名詞、代詞,意思是"足夠;充分"。作代詞可以代替可數名詞或不可數名詞,在句中作主語或賓語。
例句:
Enough has been said on this subject. 關于這一問題說得已經足夠多的了。
No, thanks. I've had enough. 不,謝謝。我已吃飽了。(enough=enough food)
注意:當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,要用介詞of。如:
We've had enough of your coldness. 我們已經受夠了你的冷漠。
二、enough作形容詞,意思是"足夠的;充分的",常與for或不定式連用,可以作定語或表語。作定語置于被修飾的'名詞前后均可,前置時強調enough,后置時強調被修飾詞。
例句:
Five men will be quite enough. 五個人就足夠了。
三、enough作副詞的意思是 "十分地;充分地;足夠地;充足地",置于被修飾的形容詞或副詞之后,常與不定式或介詞for連用 ,在句子中作狀語,表示程度。
例句:
When they reached the burning building they found that their ladders were not long enough to reach the people who were trapped.
當他們靠近烈火熊熊的大樓時,他們發(fā)現梯子不夠長,夠不著那些被火圍困的人。
四、enough作感嘆詞時意思是"夠了;停止;住手;不要再繼續(xù)了",用以表達不耐煩或惱怒。
例句:
You've been practising the violin all afternoon. Enough! 你整個下午都在練小提琴。夠了!
五、用在"主語+cannot...+enough"句型中該句型形式上是否定句型,實際上表達的是肯定意義,意思是"再……也不過分;越……越……"。
例句:
I cannot thank you enough. 我對你感激不盡。(我怎么感謝你都不算過分。)
