Giving the ideal speaking is a matter of cofidience in yourself and in what you are going to say. Its success lies in your careful preparation. Note down your key points but don't try to read the whole thing word . It may give you a sense of security of doing this, but when you start reading it it will sound unnatural. Keep il brief. It's no good saying afterwards; "I gave it well but they fell asleep". Begin your talk with a few thoghts or phrases, or even a joke. Being a beginner you'll show your nervousness in your face as you wonder whether your joke will be successful. Be a top-class speaker, not an amateur comedian.
