从释义，用法，使用环境，形象和影响范围五个维度分析had been与has been的区别，详细内容如下。

1. 释义区别：

- "Had been"是过去完成时的形式，表示在过去某个时间点之前已经发生或持续存在的动作或状态。

2. 用法区别：

- "Had been"常用于过去完成时，用于描述在过去某个时间点之前已经完成或持续的动作或状态。

- "Has been"常用于现在完成时，用于描述从过去某个时间点开始，一直延续到现在的动作或状态。

例句：

3. 使用环境区别：

- "Had been"常用于描述过去某个时间点之前已经发生或持续存在的事情，适用于过去时态的叙述。

4. 形象区别：
