In my life of 12 years old, there is such a lesson that I will never forget. "Jingle bell ..." The bell rang, and the students poured into the classroom and returned to their seats. But the students are still immersed in the state of class, and some students are looking around; Some students are whispering; Some students are fidgeting in their seats. The teacher came with a computer. The students feel very strange. The teacher found a set of pictures and put them on the big screen. These pictures all describe the lives of some poor rural children. Among so many pictures, one touched me the most: there is a little girl named Liu Xiaohuan in the picture. In order to earn a living and tuition, she has to carry 16 big bricks weighing about 80 kilograms and walk 140 meters every day, while she is only 1 1 year old. Although I can't see her face clearly, I can feel the bitterness and sweat on her face. Her rickety back should be straight, but the oppression of life made her unable to stand straight. Maybe, I think it's too hot. When blowing the air conditioner, Liu Xiaohuan was carrying bricks in the scorching sun. Perhaps, when I was still asleep, Liu Xiaohuan got up early and chopped wood to do housework there ... In order to meet some requirements, I asked my parents for this and that. But Liu Xiaohuan probably has to carry hundreds of bricks to get what she wants. Thinking of these, my heart is very heavy. I was deeply moved by her strong will. If it were me, I would have given up. But Liu Xiaohuan did not give up his studies. In order to go to school, she carries bricks every day during the holidays. After two months of hard work, she finally raised the tuition. The noisy classroom became quiet at this moment. Some students can't help crying. The teacher explained in detail, the speech speed became slower and slower, and the voice became lower and lower. We listened carefully. The atmosphere in the whole classroom was very heavy, and every student was completely infected. ...

"Jingle bell ..." The bell rang suddenly. In the past, students would rush out of the classroom like the wind, but today, students have been looking at these pictures until the bell rings in the next class. I will never forget this lesson.
