时间官

Everybody, Good evening, I'm a timer. My duty is to help you control your time. Here are the timing rules:

For speeches within 3 minutes:
when I show the green card, it means you have 1 minute left;
when I show the yellow card, it means you have 30 seconds left;
when I show the red card, it means time is up, please conclude/end your speech in 15 seconds.

For speeches over 3 minutes,
when I show the green card, it means you have 2 minutes left;
when I show the yellow card, it means you have 1 minute left;
when I show the red card, it means time is up, please conclude/end your speech in 30 seconds.
At the end of the meeting, I will give you my timer report.

I believe that everyone is a self-disciplined person.
Because everybody is qualified！Congratulations!!!
