very，too和enough虽相近，但弄混的话，有的时候褒义会变贬义
Very，too 和 enough 都可以作程度副词，而且在意思上非常接近，因此常常让人困惑，特别是 very 和 too 的区别。有的时候用错了，褒义就变贬义了，所以要特别引起重视。
一、very
Very 作副词时，直接置于形容词或副词之前来强调它们，表示某种程度的加强（intensify），例如：
修饰形容词（限定词）：
I'm very very grateful.
我万分感激。
The photos are very beautiful.
照片很漂亮。
Very few people know that.
很少有人知道那件事。
修饰副词：
I like your dress very much.
我非常喜欢你的衣服。
Think about it very carefully before deciding.
在决定之前要仔细考虑。
被 very 修饰之后，被修饰成分在程度上的差别：
二、too
Too 中有两个”o“，暗示过度，通常有否定的味道，置于形容词或其他副词之前表示超过了某个度，例如：
修饰形容词（限定词）：
There is too much sugar in this tea.
这茶里糖太多了。
Her words seem too good to be true.
她的话好听得不像真的。
修饰副词：
This lady talks too much.
这位女士说得太多了。
The car was travelling too fast and went out of control.
汽车开得太快，失控了。
The clerk at the counter gave me too little change.
柜台的售货员少给我找了零钱。
被 too 修饰之后，被修饰成分在程度上的差别：
三、enough
Enough 用来表示达到所需要的程度或数量，修饰动词、形容词或副词，且紧跟在这些词后面，例如：
修饰动词：
I hadn't trained enough for the game.
对比赛我训练得不够。
I don't think he's really experienced enough for this sort of job.
我认为他没有足够的经验做这种工作。
修饰形容词：

这个箱子够放那些书吗？
He is old enough to take care of himself.
他已经长大了，可以照顾自己了。
修饰副词：

四、三者的区别
1. 强调形容词或副词时，用 very，而不用 too 或 enough；very 表示某个程度得到加强，too 表示超过了这个程度，enough 表示刚好达这个程度，例如：
他很强壮。
✔: He is very strong.
❌: He is too strong.
❌: He is strong enough.
2. 修饰如 little，few 或 many 等限定词时，用 very 或 too，而不用 enough，例如：
现在学拉丁语的学生少得很。
✔: Very few students learn Latin now.
✔: Too few students learn Latin now.
❌: Enough few students learn Latin now.
3. 修饰动词时，用 enough，而不用 very 或 too.
我认为你已经做得够多了。
✔: I think you have done enough.
❌: I think you have done very.
❌: I think you have done too.
