When you present your speeches tomorrow you can make the speech last longer by pausing for Commas, Full stops and to connect with your audience. When you connect with the audience you should make eye contact and ask questions to check that your audience understands.
DO NOT SPEAK FAST IT WILL MAKE YOUR SPEECHES SHORTER AND PEOPLE WONT UNDERSTAND. IF YOU PANIC OR GET NERVOUS COUNT TO 10 SLOWLY TO RELAX THEN START AGAIN.
I am really looking forward to hearing your speeches. I know you will all do a good job. )
