As for today's presentation, it’s really rushed. We decided to change the topic just before the day we have to show it. So it was lack of preparation. Taught By this lesson, we knew that we should choose some simple article as our topic. If everything is not well prepared, although the topic can be appealing,there have no possibility to attract our audiences. This time I got a new partner, hopefully, we can do better next time. The topic don't need crazy simple, but we need prepare it when we start to organize the outline.The practice of presentation must be in advance.
