Also, don't panic. If you reach a point in a sentence where you can't think of the right word, try thinking of a different one. Forget the word and just try explaining what you mean using different words. You will be amazed at how many words you actually know.
Hopefully your teacher realises the importance of getting students to speak out loud and doesn't worry too much about correcting every tiny mistake. Encouraging you to talk at all is the important thing.
Please also look at the amendments I made to your post. Be careful with punctuation. You must put a space after a comma. Your sentences are very long so read your post back to yourself before you submit it. Make sure there are breaks in natural places - those are the places for either a comma or a full stop.
There was one part of your post I couldn't understand - what does "it's a adult taking show coure" mean?
