1.这个区别很简单,关键是看那个形容词是什么单词.
2.如果该结构中的形容词是表示数量多少的much或little,则用so；
如果该结构中的形容词是除了much和little之外的任意形容词,则用such.
3.楼主给的例句中,形容词是good,不是much/little,所以当然用such.
再如：He has so much money that he often buys some expensive cars.
There is so little water in the bottle that we are all thirsty.
It is so good weather today that we would like to go out to play.
