作完一个演讲，对听众表示感谢，这句话怎么说？

That' all.thank you!
或者：thank you all
那就是this is the end of my speech. thank you very much for being here.
or
i have finished delivering my speech. thank you for your support (if that applies to you) and your kind attention.
or
i am very glad to be here today to share my thoughts with all of you. (this is more like the beginning of your speech though).
but you can write i am very glad for being here and having shared my thoughts with all of you.
I'd appreciate you all for careful listening
"Thank you for listening. I appreciate your kind attention."
这些都不常用的，如果你喜欢专业的就挑个吧
恩，还有啊，可以用名人名言结尾的，比较雅致的方法

我觉得应该是That is all，thank you

您好！

可以这样回答：
That's all.Thank you very much!

暂时只想到这一种，希望对你有所帮助！
