英语开麦时怎么说

To open the microphone in English, you can say "Can I have the microphone, please?" or "Can I speak now?" or "May I have the floor, please?" or "May I speak now?" These are all polite ways to request the microphone and indicate that you would like to speak. You can also simply say "Can I speak?" or "I'd like to speak now." It's a good idea to use one of these phrases to signal to the person who is currently speaking or to the person in charge of the meeting that you would like to speak next.
