Editing by Audacity

This semester, I taught TOEIC listening part. We had 3 tests. before this class, I have no idea about editing audio file. So, I took 2 written test because there's some problem for editing. However, final test was listening test. I am not good at using audacity well. But I tried to make it. This file is made by me. It's not a perfect. I just did cut and paste by clicking. I may do better next time if I had a chance to do it.
