Speaking
Give a 5-minute presentation on one of the following topics. Use the Extemporaneous Method of Delivery.
1) Hot-Air Balloons
2) Floating Airships
3) Kites
| The Extemporaneous Method of Delivery This method is described as the most effective one. It is based on: ● thorough preparation; ● memorizing the main ideas; ● abbreviating the manuscript to a number of key words and phrases. Advantages: ● this method allows you great flexibility (you are not fixed on the exact wording ➔ you are free to extemporize depending on the feedback from the audience); ● with this method it is easy to be natural; ● this method comes closest to ‘enlarged conversation’, which is an ideal form of public speaking; ● your physical freedom (you are not tired to the script➔ you can move freely, use body language and interact with the audience).
