Please advise the difference between" so much" and "very muc

Please advise the difference between" so much" and "very much "in Business English,thanks.

very,much,so 都有“很,非常”的意思.它们之间有什么区别呢?
我们先来了解一下,这三个词本身都有与别的词不同的意思.它们之间不同的含义应该容易区分.例如：
1、very 本身有个特殊的含义,就是起强调作用.例如：
Your very presence will do.你只要出席就可以了.
He is the very man that came yesterday.他正是昨天来的那个人.
He was caught in the very act of stealing.他正在偷东西时当场被捕.
2、much 有“许多的,大量的”的意思,是形容词.例如：
He hasn't much money left.他剩下的钱不多了.
There is not much hope.无多大希望.
Much coal has been saved.节省大量的煤.
3、so 有两个特殊的含意,一是代表前面说过的事物(代词)；而是表示“因为,所以”等(连词)；
I think so.我想是这样.
Well,I told you so,didn't 我不正是对你这样说的吗?
You say he is dilligent; so he is.你说他很勤奋,他确实很勤奋.
He was sick,so they were quiet.他病了,所以他们很安静.
It was late,so we went home.天晚了,所以我们就回家去了.
He was sick,so they were quiet.他病了,所以他们 很安静.
但这三个词都有一个相同的意思,即都能表示“很、非常” 的意思.用语法的词汇来说就是它们都是表示“程度”的副词.这时,它们有什么区别呢?请大家多看例句,再进行思考小结.
1、very 一般只修饰形容词或副词.
very quickly 很快
a very good cake 很好吃的蛋糕
a very exciting book 一本非常有趣的书

2、much 有“非常、很”等意思,但它修饰的词类不同.
(1) 可以修饰动词

3、so 也有 “非常,太”等意思；但它还“这么、那么”等意思.
(1) 有“非常,太”等意思,修饰形容词.这时可以与very 互换.
I'm so glad to hear from you.接到你的来信,我非常高兴.
It's so kind of you.你太好了.
I feel so guilty and angry about the whole issue.　对整个问题我感觉非常内疚和气愤.
(2) 在表示程度时还有“这么、那么”的意思.

(3) so 可以与 many,few,much,little 等连用,表示“这么、那么”的意思.
