这是一道“用适当形式填空题”，求助各位高手，这道题是什么结构，分析一下句子成分。非常感谢？

They walked out of the classroom,___(talk)loudly about a math problem.

Answer 1

填写：talking.
现在分词引导的短语做伴随状语。
They walked out of the classroom, talking loudly about a math problem.
他们走出教室，大声地谈论一个数学问题。
这个句子是用逗号分开，所以用现在分词。
如果不用逗号，也可以用下面形式做并列谓语：
They walked out of the classroom and talked loudly about a math problem.
