把“ ，我擅长拉手风，我每天都拉30到40分钟，这几天拉得有点不好，下次有机会给大家拉一曲”翻译成英语

楼主要求的应该是口语吧

I was good at playing accordion. I always play it thirty to forty minutes everyday, but it isn't going well recently. I 'll perform to you next time.

Accordion is my forte which I spend 30 to 40 minutes on everyday. But I'm out of condition these days. May be next time I will play it.
