听力原文： OK, everybody. Be quiet, please! Can we begin the meeting now？ I am Mike Johnson

, the chairman of the Graduation Committee for this year. I am honored to declare that all of you have been chosen as representatives to plan the graduation ceremony. Within a moment, I am sending around a sheet of paper for each of you and you are required to write down your names and telephone numbers. Also, please write down which part of the ceremony you'd like to work on. Remember, as a representative, you will have a lot of responsibilities to shoulder. So only sign up if you feel you have the time to participate. When everyone has finished writing down the information, please return the paper to me. What's more, the time for next meeting has been changed. Yesterday I said that it would be held two days later. But now after our further discussion, it will be on next Friday. At our next meeting, one week from today, we will start to discuss the details of the graduation ceremony. At last, I would like to say that in the coming month we may have several other meetings in celebration of our school's great success in education, please keep them in your mind and do your best in them!
