之所以用过去分词,是受seat这个词本身决定的.
seat多数情况下是名词,座位的意思.
作为动词,seat后面必须跟人.如果用人作为主语,则必须用被动.I am seated.我就坐了.
在这个句子里,seated是被动式,过去分词作伴随情况.
用现在分词的情况出现在主句的主语和伴随情况的句子的主语一致的时候.比如：
Sitting at the table,my father and I were talking about my job.
My father and I sit at the table.
My father and I were talking about my job. 之所以用过去分词,是受seat这个词本身决定的.
