我临时接到老师的通知要参加戏曲节目的演出排练，这次演出对我来说是非常重

I was temporarily informed by the teacher to participate in the rehearsal of the performances of the drama program. This performance is very important to me, more important than climbing. Fish and bear's paw can't have both, so I can only give up climbing with you. Moreover, we still have many opportunities to go mountain climbing together. But this performance is only once, too precious for me. Therefore, I am very sorry that I did not keep my promise.
