Grammar explanation-语法解释

enough means ‘as much as necessary’. It can be used with an adjective, an adverb, a verb or a noun. It can also act as a pronoun. “enough”的意思是“尽可能多”。它可以与形容词、副词、动词或名词一起使用。它也可以充当代词。

With adjectives and adverbs-和形容词和副词一起使用

enough comes after adjectives and adverbs. “enough”接在形容词和副词后面。

I’m not tall enough to reach the top shelf. 我不够高，够不到架子的最上面。
Your marks are good enough to study engineering at university. 你的成绩足以在大学学习工程学。
I couldn’t write quickly enough and I ran out of time. 我写得不够快，时间不够了。
I’ve helped at conferences often enough to know what can go wrong. 我经常在会议上提供帮助，知道可能会出现什么问题。

With verbs-和动词一起使用

enough comes after verbs. “enough”接在动词后面。

I make sure I drink enough during the day. 我确保白天喝足够的水。
I don’t read enough but I’m going to start downloading books to my phone. 我读的书还不够多，但我要开始将书籍下载到手机上。

With nouns-和名词一起使用

enough comes before nouns. “enough”出现在名词之前。

There isn’t enough bread to make sandwiches. 没有足够的面包来做三明治。
Have you got enough money? 你有足够的钱吗？

As a pronoun-作为代词

enough can also be used without a noun. “enough”也可以不带名词使用。

I’ll get some more chairs. There aren’t enough. 我再去拿几把椅子。还不够。
A: Do you want more coffee? B: No, I’ve had enough, thanks. A：你要加点咖啡吗？ B：不，我已经受够了，谢谢。

We know what the noun is because of the context. 由于上下文我们知道这个名词是什么。

With an adjective and a noun-带形容词和名词

When enough is used with an adjective and a noun, two positions are possible but the meaning changes. 当“enough”与形容词和名词一起使用时，可以有两种位置，但含义会发生变化。

We haven’t got big enough envelopes. 我们没有足够大的信封。
We haven’t got enough big envelopes. 我们没有足够的大信封。

When enough is after the adjective (big enough envelopes), it describes the adjective – the envelopes are too small. When enough is before the adjective (enough big envelopes), it describes the noun phrase – we have some big envelopes, but we need more. 当形容词后面有“足够”（足够大的信封）时，它描述的是形容词——信封太小了。当形容词前面有“足够”（足够大的信封）时，它描述的是名词短语 - 我们有一些大信封，但我们需要更多。

enough of-够了

We normally only use enough of when it is followed by a determiner or a pronoun (a/an/the, this/that, my/your/his, you/them, etc.). 我们通常只在后面跟限定词或代词（a/an/the、this/that、my/your/his、you/them 等）时才使用“enough of”。

There isn’t enough of that bread to make sandwiches for everyone. 没有足够的面包为每个人做三明治。
I’ve seen enough of his work to be able to recommend him. 我已经看过足够多的他的作品了，可以推荐他。
There’s enough of us to make a difference. 我们有足够多的人来做出改变。
