听力原文:Good morning. It' s great to see so many people here for our Visitors' Day. I hope you'll enjoy looking around the college, and you will be able to get answers to any questions you may have. At 11 o'clock, refreshments will be served in the main refectory. We begin today, however, with a short talk from one of our many successful alumni. Fatima Jackson is a former student of whom we are very proud. She has come today to tell us about her career and how the education she gained at this institution has aided her. I hope her story will be an inspiration to you all. What is the purpose of this short speech?
