Presiding over a Meeting 主持会议（一）
Ladies and gentlemen, may I have your attention, please?
Welcome to our meeting.
I would like to express my welcome to all the participants here.
It is my home to introduce today's keynote speaker, Mr. Black.
Let's welcome Mr. Black.
That's true. I totally agree.
That's right. It's a very good idea.
No, I don't think so.
I'm sorry. Could you explain it? I'm not very clear about that.
Can you give us some examples?
Go on. What else?
