I edited your article a little bit. Just some suggestions. :)
When I was (still) in (2nd grade, ) my elementary school Grade II one day, when I was taking a class, I was asked by my class teacher to go to the recording room. She and another teacher asked me to read the Aesop's fable "A crow drinking water " in the textbook.
The beginning (of the fable) was ”A crow was thirsty. He was looking for water everywhere. " My teacher asked me to emphasize the word "everywhere" to show how hard it was to find water. It (That) was the very beginning (of my) when I had the public speaking training.
My recording of the fable was finished in 45 minutes. When it was played in the teachers' office, I could not believe it was my voice as it sounded exactly like a radio voice.:) And then it was played in every class of my grade. Soon after, I was selected as the MC of my elementary school which was (had) more than 1000 students. I was trained in my expression management and my posture, such as including 丁字步,and etc., at that time.
I hosted all kinds of school events including the yearly (or annual) International Children's Holiday.
Maybe because I had the public speaking training so early, I became (have been) very brave and confident since then. And I
believe that as long as you work hard, you would be successful.
That is why I insist that EVERYONE takes turns to be anchors in MYSJ to host all kinds of programs. It would be helpful in training (building) one's confidence , responsibility and the (ability of) time management ability.
