A heart-warming scene has moved people a lot in Hunan University of Science and Engineering.There is a student named Li Jiqin. （1）He has become unable to walk since he was at a young age.
    Even though it is not convenient for him to move，he has never been late for school because his mother used to carry him to school.But now it is too hard for her to carry a son who weighs more than 75 kilograms. （2）所以他擔(dān)心他是否能按時上學(xué)。
    When the teacher Chen Huiling asked for volunteers from Li's classmates to help carry him up and down stairs（樓梯） to classrooms，all 30 boy students from Li's class agreed to help him. （3）男生們被分成了五組。And they take turns to carry Li to the classroom.Every day，when Li rolls his wheelchair to the teaching building，a strong classmate carries him on the back，with two assisting and two carrying his schoolbag and other things. （4）Because of Li's weight，the classmate who carries him needs rest for a while after climbing stairs to classrooms. Li thanks his classmates a lot every day.
    （5）Li said that he felt the warmth from the class，and would try his best to study hard. He chose to study computer science and technology because of his interest and physical condition.He would like to be a programmer after graduation.
