Your friend often feels nervous when speaking in front of a large group of people. What suggestions would you like to give to this friend of yours?
There may be some reasons why he dare not speak in front of people. Firstly, he may feel nervous when standing in front of a group of strangers. For this, he could practice in front of relatives and friends first and then practice in front of some new friends. Secondly, he's afraid he may forget the lines during the presentation. For this, besides reciting more and practicing more privately, he can make notes cards so that if unfortunately he forgets the lines, he can refer to the key points.
