我知道There be 与have（实义动词,有）不能连用,但此处“There had been ……

there be 和 there has/have been have与there be there be 句型能跟have连用吗? 为什么both 与复数动词连用,但 both… and…可与单数名词连用. there are...there will be还有there have been都是there be句型吗? there be 与 there have的区别? have been there与 have gone there的区别 have/had + been/be? she had't been there before 与 she had nver been there before I have been there.此句汉语意思：（1）我一直在那里.（2)我去过儿. have been there 和 have lived there 有啥区别? 现在完成时go怎么变书上讲非延续性动词要变延续性动词,go要变be there.但我也看到过I have gone to
