hasn’t always been that 与 does not always been that 的区别
我知道前一个是对的 我想问后一个为什么是错的 怎么样才算对
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.
再问: 这个。。。has不也是助动词吗?
再答: 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 it He has gone home It has been wonderful We have finished eating 等等。
