I was far behind most of my classmate when I become a senior three student. Moreover, I couldn't follow the teacher completely in class. One day, I was too much exhausted and confused to concentrate on which the teacher taught. Unfortunate, I was invited to share my own idea. As you can imagine, I couldn't say a word. Feeling embarrassing, I ready to be criticized. Much on my astonishment, the teacher instructed and encouraged me patiently. I was such touched that I was determined to try his best to study hard. Now I am quite confident about my study.
