问题描述:

He has never been heard to speak ill 2到4的单词是什么结构求解

has never been heard 是现在完成时的被动结构.
现在完成时的被动结构构成为:has/have+been+动词的过去分词.如:
The work has not been done by him.
这项工作他还没有完成.(即工作没被完成.)

如满意,请采纳为“满意答案”.祝进步!为什么不用主动形式而用被动呢在没有必要提出动作的执行者时,用被动好于主动。比如本句的句意为“他从来没有被听到说……的坏话。”所以此处没有指出是谁没有听到他说……。如果改为主动,则是:People have never heard him speak ill of...。
