how \what ,such...\so that的区别和各自的用法？谢谢

1.what与how
都是疑问词。简单说，what一般是名词性质，做主语、宾语、表语，how一般是副词性质，做状语。
e.g. What is your name?（表语）
What are you going to do?(宾语）
How do you like the book?（状语）

2.such...that.../so...that.../so that...
such...that...和so...that...都是“如此……以至于……”的意思,不同的是so后面接形容词或副词，such的固定搭配是“such + a/an + 形容词 + 名词”
e.g. You are so lovely （a girl) that I would like to be friends with you. (括号里的表示可省略）
You are such a lovely girl that I would like to be friends with you.

so that...是“为了……”、“以至于……”的意思，可引导表目的的状语从句或表结果的状语从句。接表目的的状语从句时，从句中有情态动词；接表结果的状语从句时，从句中没有情态动词。
e.g. I need to hurry up so that I could get there on time.(so that 引导表目的的状语从句）
I woke up at 8:30 so that I was late for the class.

how表示怎样 what表示什么 such接名词 so接形容词
