hasn’t always been that 与 does not always been that 的区别

do 和 does 是助动词,后面要接 动词原型,比如
He does always eat a good breakfast every morning.
We do always help mom with housework.
They do always clean up after they finish eating.
等等
你的第二句不符合语法规则.这个。。。has不也是助动词吗？这里动词 has 表示完成时态，要接动词的分词形式，比如I have done itHe has gone homeIt has been wonderfulWe have finished eating等等。
