四. 短文改错

I still remember how nervously I was on my first day in the new school ten years ago, when I found difficult to follow my teacher in the first English class.

The teacher spoke English throughout the class, that was totally different from the lessons I had been taken before.

In the morning class the next day, the English teacher came to me while I am reading the text aloud as other students. After listen to me for a while, she gave me a big smile and said he liked my voice very much. The smile shone on a whole day and the following days, as a result of that I began to be confident.

A week later, I volunteered to take charge of English study in my class and my English is now been improved steadily.
