Mistakes during presentations
Body language is one of the most important ways to communicate with others． 36 Here are three main body language mistakes you should avoid during presentations．
1．Crossed arms
Crossing your arms might give your audience the impression that you are not enthusiastic about your presentation． 37
Keep your back straight，your head up，and your chest and arms “open’’ when you are delivering a presentation．It will give a message of confidence to the audience and make you an approachable presenter．
2．Jiggling(抖动的)legs
Moving your legs from side to side indicates that you are uncomfortable and restless.
Try moving in the space around you when you are giving a presentation. It is a powerful way to keep the audience attentive． 38 Move when you need to emphasize(强调)a point.
3．Rolling eyes
Most psychologists think rolling eyes is an indication of lying. To some extent，when you roll your eyes during presentations，you are telling the audience that you don’t respect them.
Begin your presentation with a smile unless you are delivering horrible news． 39 As a result，they will be more willing to listen to you and more likely to be persuaded.
If you use body language inaccurately，the audience may be easily distracted(分心)from your presentation or even conflict with your ideas· 40
