這兩個詞都是形容詞,又都表示“足夠”、“充足”之意,但詞義和用法有所不同。

(一)一般來說,enough指心理上的滿足(mental satisfa);suffit則指需要的滿足(satisfa of demands)。例如,某個貪心漢已撈了很多錢(suffit money),足夠他吃喝一輩子,但他依然感到不滿足(not enough)。例:

Remember that sce requires the effort of a lifetime.Even if you had two lives to give,it would still not be enough.

要記住,科學需要人畢生的精力。即使有兩次生命,也仍然不夠。

That sum of money is suffit for our requirement.

那一筆錢已足夠我們的需要。

(二)就文體而言,suffit比enough更為正式(formal);suffit常用以指程度上的足夠;enough則指數量上的足夠。例:

Our military respon to the aggressive act was limited but suffit to show our determination.

雖然我們對侵略行動的軍事反應有限,但足以表明我們的決心。

There is enough food for five people.

食物足夠五人吃。

(三)enough既可作形容詞,又可作副詞和名詞;suffit隻能作形容詞。例:

Are the shoes large enough?(adv.)

這些鞋是否夠大?

I''ve had enough,thank you.(n.)

我已吃飽了,謝謝。

(四)enough作形容詞時,可以放在它所修飾的詞的前麵或後麵;作副詞時,一般放在它所修飾的形容詞或副詞的後麵。例:

I have enough bread(or bread enough).(adj.)

我有足夠的麵包。

You are not careful enough.(adv.)

你不夠仔細。

(五)enough之後可以接不定式,但不能接以that引導的從句。例:

I know them well enough to ask them for help.

我和他們很熟,可以請他們幫忙。
