Answer 1

Correct version:

 

When I did my presentation, I felt as though I was going to swoon.  I was afraid, feeling my voice going up and down.  I had to speak very fast because there was not enough time.  I did not know what I had said.  I was really confused.  So far, I have not grasped what I had done.  Before the show, I was looking forward to doing the presentation.  I was excited to use picture slides to tell my story in order to engage and educate the audience.  Now, I feel like I have done something special with my group.  I felt happy because the teacher informed me I have been wonderful.  We were a special party because we ended our latest presentation.  Now, I feel I can do anything that seems impossible.
