Then there is the general, all covering apology, which avoids the necessity of identifying a specific act that was particularly hurtful or insulting, and which the person who is apologizing should promise never to do again. (06.1 Passage 2)

　　主干：there is the apology

　　这句话用的是there be句型，主干部分容易理解。主语apology带了多个修饰语，包括前置修饰语general和all covering，后置修饰语是一个which引导的非限制性定语从句。在该定语从句中，介词of+动名词短语identifying...作定语，修饰the necessity;identifying的宾语a specific act后面带了两个定语从句，一个是由that引导，另一个是由which引导，这两个定语从句用and并列链接。which引导的定语从句中，主语the person也另外带有一个who引导的定语从句。

　　译文：然后还有一种泛泛的无所不包的道歉，这种道歉避免了指明特别让人伤心、特别令人委屈，道歉者应该保证不会再犯的具体行为。
