希望各位老师对我今天的表现能够满意 用英文怎么说阿？

ann8306 的回答不错，不过用dear teachers 在这种场合不是很恰当，不够正式，我觉得这样改比较好：I hope my performance today could satisfy you .Thanks all teachers.

Dear teachers, I hope my performance today could satisfy you all.

Dear teachers,I hope all of you are content with my performance today.

hope my performance left a deep impression on you
