TED Summarize (Catherine)

After I listened three person's presentation, I learned a lot skills and experience from them. It's a good way to begin with a joke with confidence and tell the audience directly with my opinions. Besides, it can be started seriously and more formal, but it maybe less a little bit interesting. The good presentaiton should be has a good organization and clear content through their talking. They can show their life experience either. There is another important thing is visual languages. More specific is display some sketches, photographs, videos and even some props.
