Lets Warm Up的意思|示意

让我们温暖 A loud screech came from the speaker system and my attention, along with everybody else's, went straight to the noise. It was just Brody, attempting to tak into the microphone. He didn't look really familiar with it I noticed. "Lets warm up!" He finally managed to crackle out. "We will start the lessons in fifteen minutes." Then he sat down the microphone on the table, and walked towards the snack shack with the large people following close behind him, but giving him enough space so it looked natural.
