用简短的英文回答保研面试问题：课余活动我各种都参加过一点但比较浅尝辄止吧。大一参加过社会实践的项目以优秀的评级结项；一直在乒乓球社团参加了院系杯；大二参加过129合唱团；大二开始担任团支部的组织委员。

I have participated in various extracurricular activities, but mostly on a superficial level. In my freshman year, I participated in a social practice project and received an excellent rating. I have also been a member of the table tennis club and participated in the inter-departmental tournament. In my sophomore year, I joined the 129 choir and in the same year, I took on the role of organizing committee member in the student union.
