过去分词（Past Participle）是 英语动词的一种形式，通常用于构成完成时态和被动语态。它主要有以下几种用法：
构成完成时态：
现在完成时由“have/has + 过去分词”构成，表示过去发生的动作对现在造成的影响或结果，如：
She has finished her homework.
They have arrived at the station.
构成被动语态：
过去分词可以跟助动词“be”一起构成被动语态，表示主语是动作的承受者，如：
The book was written by her.
The experiment was conducted by the researchers.
作为形容词：
有些过去分词可以转化为形容词，用来修饰名词，表示状态或特征，如：
The broken glass cut his hand.
I saw a painted horse in the field.
作为副词：
某些过去分词可以转化为副词，用来修饰动词、形容词或其他副词，如：
She spoke highly of him.
They arrived quickly after the meeting started.
构成复合形容词：
有些过去分词可以与其他词组合，构成复合形容词，如：
