有一个英语语法填空题要请教大家
i stood there____(puzzle)
这个空应该填什么呢?答案是puzzled,但是我还是有些不太理解,在这里是puzzle的过去分词作什么成分呢?

过去分词作伴随状语.原句相当于 I stood there and I was puzzled.我困惑地站在那里(即“站在那里的同时,心里困惑着”.是一种伴随的状况)
又例如:She entered the classroom, and she was followed by some students.=She entered the classroom, followed by some students. 她走进教室,后面跟着几个学生.
