I had never heard 还是 I have never heard 两者什么区别

Question

I had never heard 还是 I have never heard
两者什么区别

Answer 1

口语上表达肯定是I have never heard...用现在完成时表示我(迄今为止)从未听过..., 过去完成时对现在没有影响--注意: 过去完成时不能孤立存在, 必须建立在一个过去时的基础上才可以, 不然无意义,
如: 1. I had never heard of TF boys before he told me. 此处用had因为hear发生在tell前面。2. She really impressed me a lot for I had never heard a more beautiful voice.此处hear发生在impresse前面。

Answer 2

前者用于描述过去的故事时某一时间之前的行为（动作），后者描述到目前（说话时）为止的行为（动作）。

Answer 3

一般说第二个，第一个是过去完成式，比较罕见
