过去分词作宾语补足语，表示其动作已经完成或结束。能用宾语补足语的过去分词一般都是及物动词，表示被动意义或已完成的意义，有时候两者兼而有之。作宾语补足语的过去分词与宾语有逻辑上的动宾关系，即宾语是过去分词动作的对象。

②表示“遭遇到某种不幸；受到打击”等。如：Myeldersisterhadherwalletstolenonabuslastmonth.Theoldmanhadhiswristbrokenintheaccident.(2)”make+宾语+过去分词”，在这种结构中，过去分词的动词必须是表示结果含义的，如：Iraisedmyvoicetomakemyselfheard.TheymanagedtomakethemselvesunderstoodusingverysimpleEnglish.

3.过去分词用在感官动词watch,notice,see,hear,listento,feel,find等的后面

当我们到学校时，我们看见门锁着。Whenwegottoschool,wesawthedoorlocked.

4.过去分词用在want,wish,like,expect,order等表示“希望，愿望，命令”这一类动词的后面作宾语补足语。
