so .that与...sothat..有什么区别还有几个问题:mary's and john's 与mary and john's 有什么区别?feeling这个名词在什么情况下用单数,什么情况下用复数.哪个英语大虾说下拉,感激不尽!

1.
so...that..表示如此。。。以至于。。。
e.g: He is so young that he cannot go to school.
...so that...表示以便，为了或者是因此，所以
e.g: I spend more time learning English every day so that I can make greater progress this year.
He is 7 years old so that he can go to school.
2.
mary's and john's表示他们分别的什么东西
e.g: mary's and john's father表示mary的爸爸和john的爸爸（他们是两个人）
mary and john's father表示mary和john的爸爸（一个爸爸）
3.
feeling的单复数要看情况定了
e.g: "what are your feelings about the crisis?"; "I had a feeling that she was lying".
he had a great feeling for music.

so...that... 这个是表结果
so that 是表目的

前面的结果
后面的目的
前面的两者分别的
后面的粮者共有的
表示情感用复数
表示感觉用单数

So...that...的so后接形容词，如此... 以致于...
so that 接一个从句，结果，以致
如：She is so kind that everyone likes her.
She is kind, so that everyone likes her.
Mary and John's 表示他们共同拥有的。。。
而前者不一定
feeling 作为错综复杂的感情讲时应该是复数吧。

1.so...that 表示结果
如：She is so young that she can't go to school.
2.so that 表示目的
如：She got up early so that she could catch the early bus,
3.Mary's and Jhon's 表示两人各有的
Mary and Jhon's 表示两人共有的
4.feeling的单复数问题与普通的名词单复数用法差不多.

so...that...如此...以致...
so that以致

so ....that是“如此····以至于····” 的意思，表结果。
...sothat..是“·····为了···”的意思，表目的。
mary's and john's 是“玛丽的和约翰的··”的意思。
mary and john's 是“玛丽和约翰共有的”的意思.
feeling是“感受”的意思，单数用feeling，复数时候用feelings.
