Good morning, my dear teachers and schoolmates,

     It's a great honor for me to make a speech on behalf of the graduating classes．How time flies ! Our junior high school lives will come to an end．

     In the past three years, we've had a beautiful school and it provides us with a good study place．Teachers are our friends．They've given us interesting lessons and we all love them．

     We've learned a lot from them, not only knowledge but also the way to solve problems in life．Thanks for our teachers' training, parents' support and the help from classmates．Without them, we couldn't have so much wonderful time．

     At last, we hope our school will become better, our teachers will be healthy for ever and all our dreams will come true．

     Thank you for listening．
