Years of elementary school have a lot of memorable lessons, but I never forget a month ago. That time the teacher left in my heart love unforgettable. On that day, my teacher wore a beautiful yellow gown. Long black hair is tied neatly on the top of the head, looking very fresh. She greeted the class with a bright smile. Classes begin. Her lecture that day was very active. Her voice was sweet, inspirational. Her eyes were always looking straight down. Those eyes always show encouragement, encouraging us. She lectured so passionately that on the gentle face has been sweat she has not noticed. She lectures very easily. Through this teaching, I feel the beauty, the beauty of each poem, the text. The words she preached deep into the mind never forget.

Occasionally, she went down to the back of the class, watching the students discuss the group, watching us record. She went to the school friends weak to suggest, help. She poses questions from easy to hard to stimulate our creative initiative. She is always close to the students, listening to your opinions. In the midst of intense study, she told us stories that were very useful. She told the story very attractive. Hung Hung heard her open mouth to hear without knowing. Looking at you, the whole class laughed it was fun. A drum sound is signaling the time to play. The end of the class, the faces of the class and the teacher radiant joy. I love and respect my teacher. She secretly promised to try her best to be a good person for the country as she taught us.
