so ， too ，quite， very的用法

1、首先应该先从词意上来理解：SO如此 too太……，quite十分，很；such像……；very很，非常。
2、另外从用法上：so 如此、这么，用来修饰形容词或副词，例如so heavy a desk 这么重的桌子，这里面so和heavy是一个整体
such如此、这么，用来修饰名词，例如such a heavy desk
这么重的桌子，里面a heavy desk是一个整体，这个整体是名词性的。
3、very, much, quite三个副词都作“十分，非常”解，但它们的使用场合却有所不同。

very可以修饰形容词或副词，但不能修饰动词。修饰动词的常常是much, very much或quite。例如：

The factory to be built will be very important in this city.

Many years ago we knew each other very well.

Does that matter much?

I like flowers very much.

I quite enjoy my job, so I don”t have to look for a new one.
副词quite作“完全”、“十分”、“还算”、“相当”、“确实”、“真正”解。它既可以修饰原级形容词和副词，也可以修饰动词，还可以修饰相当于形容词的过去分词或现在分词。例如：

The theatre was quite full last night.

He did the work quite well.

He is quite grown up. He should quite understand what I said.

We were quite delighted to see him at that

意思不同,但都可以修饰形容词\副词原形
so如此
too太
quite十分
very非常

so happy

too me

quiet girl

very good

简单理解吧
