What I learned from the video

We saw the video of the presentation. Someone had a good thing or bad thing to presentation.
The good thing was the memory. When we gonna to presentation we have to memory about the presentation. Then we can explain.
The bad thing was a with paper because the presentation is our knowing to explain. If we read the paper to explain, that is a not presentation, that is a reading. The bocabulary was very difficult to understand. That was another bad thing. We gonna use easy word but we must know this bocabulary then the presentainer gonna to explain with the easy the bocabulary.
