list all professional and/or business organizations to which you belong and include your responsibilities, dates of involvement, positions held, and indicate whether the positions were elected or appointed.
不是指employer吧？已经有一栏填过了，不知这是指什么？

如果排除employer的话, 可能指一些专业机构吧. 比如说,中国工程建筑协会.

我在银行里，finance, 想不出属于什么协会的。
不填还跳不过去！

如果没有的话，填N/A。
