英语翻译The most studied issue that points to the irrepaired harm of television has been the impact of media violence on children.

Answer 1

The most studied （过去分词做定语修饰issue）issue (主语) that （引导定语从句,修饰issue,为定语从句主语）points to（定语从句谓语动词） the irrepaired （过去分词做定语修饰harm）harm (定语从句宾语) of television （介宾短语作定语修饰 harm）has been （主句系动词）the impact of media violence on children （表语）.
因为定语从句 points to the irrepaired harm of television 修饰的是 issue,所以 是对对电视不可挽回的危害问题中,the most studied 被最广泛研究的是the impact of media violence on children
所以句子翻译为：（所有）对电视不可挽回的危害问题（的研究）中,被研究最广泛（/多）的是媒体暴力对未成年人（孩子）的影响.
注意：points这里是定语从句的谓语动词,第三人称单数,因为主语是 issue由引导词 that 替代.
