my classmate with you. 
       When I was at primary school, one of my classmates got seriously ill and had to be operated on at once. The operation cost too much, and his family couldn't afford it. My classmates, teachers and I donated money to help him. Moreover, we called on more teachers and students in our school to give a helping hand to him. At last, over 200,000 yuan was donated to the family. The operation was successful and my classmate returned to school three months later. 
       I think we can help others by doing small things in daily life such as donating pocket money to charities and giving a seat to someone in need on a bus. We should always remember even small acts of kindness can make a big difference to others.
