用 it is/was the first time that＋过去完成时造句

用 it is/was the first time that＋过去完成时造句 it was the first time 后面为什么要用过去完成时 用以下的短语造句..there was a time when..it is the first time that.. it was the first time连接过去时还是过去完成时? That was the first time (that) I had been in Rome.为什么用过去完成时? it is/was the first time that有什么用法 it is the first …time that造句,快 用It was the first time……that I'd seen句型造句, 用This was the first time that 造句 It was the first time that I ----- ------ ----- ----- ------ it is/was the first time +that+clause中从句用什么时态? 用it's the first time...that造句?
