过去分词可以表被动吗?

英语中有一种"get＋过去分词"构成的被动语态.其中get与"be＋过去分词"结构中的be同样起助动词的作用.这种结构在谈论突然发生、出乎意料的偶然事件.
【例如】It is upsetting when a person gets punished for a crime that he didn’t commit.The picture got damaged (＝was damaged) when we were moving.If they make such criticisms they will get treated with the contempt they deserve.The old lady got hit by a flower pot falling from a balcony.I got invited to lots of parties last holidays.I don’t want to get mixed up with the police again.
"get＋过去分词"与"be＋过去分词"表达的被动语态并不完全相同,"be＋过去分词"既可表示动作,又可表示状态,而"get＋过去分词"则主要表示动作【例如】The police say the man was shot when they found him,but they don’t know when he got shot.
在这个句子中was shot表示状态,而got shot则表示动作.再如：另外,"be＋过去分词"构成的被动语态不用于将来进行时和完成进行时；而"get＋过去分词"可以用这些时态.
