After reading, answer the questions and complete the table. Billy's Diary Friday, 20 November. In the past, I always felt stressed when I had to give a speech. I used to spend lots of time trying to memorize my speech, but I still forgot some parts. Last week, I decided to find out what the right way is to memorize a speech. I looked online and asked friends, and I found many useful methods. I learnt how to create a speech outline. Instead of trying to remember every word of my speech, I remembered the key words first. Then I formed images of these key words in my mind, and linked them in order. Another method is to divide the speech into short sections. I practised the first section until I could fully recall it. Then I moved on to the next. This helped me to find out which parts of the speech I needed to work on the most. Finally, a friend told me that I should have confidence in myself. Nobody knows my speech except me. If I do forget some words, I shouldn't panic. Just remember the key words and continue! I followed all these great methods and my speech today was a great success! 阅读理解问题： 1. What was Billy's challenge? ________________________________________________________________ 2.
