too和enough皆可修饰名词、形容词和副词。Too表示的是程度深或数量多。Enough则意味着程度或数量超出所需要的范围。这里是一些例子：

She's too sad these days. I wonder what's wrong.
她这些天都太悲伤了。我想知道发生了什么。

I don't have enough sugar. Let's go to the supermarket.

1.关于enough

阅读下面的例子，你会发现，enough有时候位于它所修饰的词语前。例如：

What do we need for dinner? I think we have enough vegetables, don't we?
晚饭还需要准备些什么？我觉得蔬菜已经足够了，不是吗？

She feels that Tom has more than enough time to help.
她感觉汤姆有足够的时间来帮忙。

在其他的例子中，enough位于它所修饰的词语后面，例如：

你应该向约翰求助，他那么有钱，一定可以帮到我们的！

I don't think they are smart enough to take that class.
我觉得他们的智商不足以应付这门课。

看一看上面例子中被enough所修饰的词语。你会发现，enough位于名词vegetables（蔬菜）和time（时间）的前面，位于形容词rich（富裕的）和smart（聪明的）后面。如果你不能很好地区分名词和形容词，可以回顾一下词性方面的知识。
