How you calm yourself before giving a speech? Both modern research and centuries of experience from experienced public speakers suggest some practical advice. 小题1:_____ Know to whom you’ll be speaking, and learn as much about your audience as you can. The more you can anticipate the kind of reaction your listeners will have to your speech, the more comfortable you’ll be in delivering your message. Be audience-centered rather than speaker-centered. 小题2:_____ You will feel less nervous if you talk about something you are familiar with or have some personal experience of. Your comfort with the subject of the speech will be reflected in your delivery. 小题3:_____ The better prepared you are, the less anxiety you will experience. Being prepared means that you have researched your topic and practiced your speech several times before you deliver it. 小题4:_____ You are likely to feel the most anxious during the opening moments of your speech. Therefore, it is a good idea to have a clear plan for how you will start your speech. Being familiar with your introduction will help you feel more comfortable about the entire speech. If you know how you will end your speech, you will have a safe harbour in case you lose your place. If you need to end your speech ahead of time, a well-delivered conclusion can permit you to make a graceful exit. 小题5:____ One of the symptoms(症状) of nervousness is a change in your breathing and heart rates. Nervous speakers tend to take short, shallow breaths. To help break the anxiety—reduce breathing pattern, consider taking a few slow deep breaths before you rise to speak. |
