解析试题分析：This was the first time + 从句结构，从句用过去完成时，且I与leave之间是被动关系，故用被动语态，故选B.
考点：固定结构及语态考查题
点评： It/This is the first time + 从句结构，从句用现在完成时；It/This was the first time + 从句结构,从句用过去完成时。语态概述 英语的语态是通过动词形式的变化表现出来的。英语中有两种语态：主动语态和被动语态。主动语态表示主语是动作的执行者。例如：Many people speak Chinese.谓语：speak的动作是由主语many people来执行的。被动语态表示主语是动作的承受者，即行为动作的对象。例如：Chinese is spoken by many people.主语English是动词speak的承受者。
