One possible version

     I still remember how nervous I was on my first day in the new school three years ago, when I found it

difficult to follow my teacher in the first English class. The teacher spoke English throughout the class,

which was totally different from the lessons I had taken before.

     In the morning class the next day, the English teacher came to me while I was reading the text aloud as

other students. After listening to me for a while, she gave me a big smile and said she liked my voice very

much. The smile shone on the whole day and the following days. A week later, I volunteered to take charge

of English study in my class.

     Thanks to the comtorting smile in my first morning class, I began to be confident.
