too和enough的區別用法
too和enough皆可修飾名詞、形容詞和副詞。Too表示的是程度深或數量多。Enough則意味著程度或數量超出所需要的范圍。這里是一些例子：
She's too sad these days. I wonder what's wrong.
她這些天都太悲傷了。我想知道發生了什么。
I don't have enough sugar. Let's go to the supermarket.
我沒有足夠的糖。我們去超市買吧。

1.關于enough
閱讀下面的例子，你會發現，enough有時候位于它所修飾的詞語前。例如：
What do we need for dinner? I think we have enough vegetables, don't we?
晚飯還需要準備些什么？我覺得蔬菜已經足夠了，不是嗎？
She feels that Tom has more than enough time to help.
她感覺湯姆有足夠的時間來幫忙。
在其他的例子中，enough位于它所修飾的詞語后面，例如：
You should ask John for help he's rich enough to help us all!
你應該向約翰求助，他那么有錢，一定可以幫到我們的！
I don't think they are smart enough to take that class.
我覺得他們的智商不足以應付這門課。
看一看上面例子中被enough所修飾的詞語。你會發現，enough位于名詞vegetables（蔬菜）和time（時間）的前面，位于形容詞rich（富裕的）和smart（聰明的）后面。如果你不能很好地區分名詞和形容詞，可以回顧一下詞性方面的知識。
a.形容詞+enough
當我們將enough作為副詞使用，用來指代要求的程度或范圍時，直接將enough放在所修飾的形容詞后面

他在理解孩子方面不夠耐心。

b.副詞+enough
當enough作為副詞來指代要求的程度或范圍時，將enough直接放在它所修飾的副詞后面。

c.Enough + 名詞

2.關于too
閱讀例子，你會注意到too可以與名詞、形容詞和副詞進行搭配使用。但是，當too和名詞搭配時，后面一般會跟上much或many。是選擇too much還是too many取決于所修飾的名詞是可數名詞還是不可數名詞。
