Secondly, i should apply more DMC skills to cultivate my content, applying more pictures and short videos.Whatsmore, the background music is an essential part. All of them can make my PPT abundent and appealling.
Thirdly, there should be quiet when i make presentation, it is my fault, the surroundings were noisy and my voice was low as i had acold at that time.
i should add some smooth introducton with confident voice.
