I used to spend lots of time trying to memorize it, but I still forgot some parts. Last week, I decided to find out what the right way is to memorize a speech. I learnt how to create a speech outline. Instead of remembering every word, I remembered key words first. Then I formed images of these words in my mind. I don't understand why I didn't try this earlier! It really works. I wonder how much more I can improve with practice. Instead of what he forgets, keep in mind what he remembers.（与其记住他遗忘的，不如记住他还记得的。） 第 页 学科网（北京）股份有限公司 $
