过去分词的用法多一些。1、过去分词用在完成时里面，和have/has/had一起构成谓语结构。现在完成时：主语+have/has+过去分词+其他。He has just finished his work.他刚完成工作。过去完成时：主语+had+过去分词+其他。Mary went on a vacation after she had taken her exam.考完试后，Mary度假去了。2、过去分词和be动词一起构成被动语态的谓语结构。被动语态：主语+be+过去分词。The dog is called Xiaohei.那只狗被叫做“小黑”。3、过去分词可以做定语。Is there anything plannedfor tonight？今晚安排了什么活动没有。4、过去分词可以做状语。
