如何用英语介绍自己的工作经验

Last summer holiday, I went to a private school to be an English teacher. The students were all very small, some of them only 9 years old,while some of them were 14 years old. I taught them words, phrases and they were very diligented, lovely and intelligent. We got along with each other very well. At first I was a little bit nervous,but because I was well prepared for it ,I had great confidence to teach them. By doing this , I got to know that nothing is impossible as long as you work hard for it.
