The news that i heard that he was killed is sorry 能转换成 I heard the news that he was killed is sorry.

恩,这句话是有点不通顺,我觉得原句的意思可能是这样表达：I am sorry to hear the news that he was killed.
就你提的这句话,虽然意思不通顺,但就你的问题而言,这两种语法表达结构也是不同的,导致了句意的不同,
前者重心在the news,可简化成The news is sorry.
后者重心在I heard,是我听说了的,听说了什么呢?是the news that he was killed is sorry.这整句话作为heard的宾语从句存在,整句话可简化成：I heard (that) the news is sorry.
因为这句话可能有错误,故不便翻译,你可以自己体会下.祝英语学习顺利.
