Dear students,

　　I'm very happy to be your guest speaker today．It's a great pleasure to visit your school and meet all of you here．

　　I would like to tell you about myself．I have been a reporter for the last fifteen years．I chose this job so I could travel the world, but the job has taught me many unforgettable lessons．My work is sometimes boring but for most of the time it is amazing and inspiring．I have seen wars, earthquakes, poverty and death．But I have also seen courage, hope and happiness．

　　In India, I visited a city．There were many homeless children in it．Some were young and lived in the streets．But then a wonderful lady called Rosa opened a home for them．In one whole year, she was looking after two hundred kids, feeding them, teaching them anti giving them hope．

　　Another time．I was in Japan and met a young girl with a serious illness．after seven operations(手术), she had to have thirteen more in hospital．However, when I met her, she was still smiling．

　　Here in China．after the terrible Wenchuan Earthquake, I found a three－year－old boy whose name is Lang Zheng．He had been in the ruins(废墟)for more than ten hours before he was found and saved out by the rescuing soldiers．Though weak and injured．the brave boy lifted his right hand above the head with difficulty and saluted(向…致敬)the soldiers around, which became the most moving moment in the disaster(震灾)．

　　Thanks to the experience as a reporter, I myself am getting braver and stronger．When I face challenges in my life．I always remember the courage of the three people．
