假设你叫李华，你将作为高三毕业生代表，根据以下要点在毕业晚会上用英文作一简短的告别演讲： 

1、对三年高中生活的怀念; 

2、对老师的感谢; 

3、对母校的祝福。 　

My teachers and fellow students, 　In a couple of weeks, we’ll say goodbye to our mother school. How time flies! Now It’s really hard for me to put my feelings into words. The past three years has been really a wonderful journey with you guys, full of laughter and tears. 　To make the journey safe and fruitful, our great teachers contributed their time, energy, love and the whole heart. Here, we are extremely grateful for all that you, dear teachers, have done for us. 　It’ll soon be the time for us to depart, though unwillingly. But it is not the end. It just means that we’re going to begin a new journey. 　Finally, on behalf of all the graduates present here, let me extend our sincere wishes for our mother school and respectable teachers. Thank you!
