should have been有should had been吗
问题描述：
should have been有should had been吗
答
没有。should have been 是将来完成时，含有虚拟语气的意思情态动词should 后面用原形 have
答
没有
答
因为should属于助动词类，后面肯定是加动词原形的，所以不会出现should had been的情况，只能是should have been，表示本应该怎样，而实际上并不是那样。
答
没有，should是情态动词后加动词原形，所以还是have
欢迎采纳~
答
没有.should have been 是情态动词完成式.情态动词should 后面用原形 have,而 have been 又构成完成式.
