在英语课程结束后，你可以说：

"That's it for today's Engpsh class."
"Okay, class is over. Thanks for joining me."
"Alright, that concludes our Engpsh lesson for today."

或者，如果你是老师，你可以说：

"That's all for today, everyone. Have a good rest of the day."
"Okay, class is dismissed. See you all next time."
"Alright, that's a wrap for today's Engpsh lesson. Thanks for your attention and participation."
