     This summer holiday, I get a chance to teach English
beginners. I experienced life as teacher for the first time.
The students were very small, but I was even nervous when
so many kids stared at me. Fortunately, their warmly welcome
encouraged me. I taught them some letter, sang English songs 
and played games with them, fill the classroom with laughter.
But little kid like talking with each other in class, so it was
hard to control the class. As a result, I got a sore throat. Thus, 
I found that teaching is cool and exciting, especially that
when you help your students to learn anything with joy.
