B. 高考应用文写作（参考范文）： Li Ming, a young volunteer in my community, has spent several years helping children with their schoolwork. He first joined a weekend programme as a university student and soon realised that many children needed regular support rather than one-time help. Although his studies were busy, he kept organising small learning groups and collecting books. His work encouraged more volunteers to join, and the programme has now reached dozens of families. What I admire most is his belief that steady, practical action can make a real difference. $
