一句很长的关于自我鉴定的英文句子,不知如何才能完美翻译,望得到答案,谢谢
In the former, I have the main duty to sort out teams for House competitions and in the latter it is essential that I communicate academic and social discipline with the younger students of the school and be of assistance to the teachers in any way possible as well as performing regular duties alongside fellow Prefects.
对不起，我希望将这个问题具体一点，在这段话的最后，"and be of assistance to the..."中的be of 是怎样的用法，be动词后面为什么加了of？这种情况具体应该怎样用呢？我想了很长时间依旧不明白其中的语法环境，我的英语不算差，但也不很棒，希望有人对此问题赐教，不胜感激。
P.S.风信子hightrue的翻译更加合理。
