She is such a nice girl that everyones likes her可以等于The girl is so nice that everyone likes 我知道可以等于She is so nice a girl

1.She is such a nice girl that everyones likes her
可以等于The girl is so nice that everyone likes her
2.The stories were so interesting that I read them again是对的
They were such interesting stories that I read them again.这句也对
因为:so有如下用法
so+形/副
so+形+a/an+名(单)
so many+名(复)
so+much+名(不可数)
such 有如下用法:
such+a/an+形+名(单)
such+形+名(复)
such+形+名(不可数)
many+such+名(复)
much+such+名(不可数)
