受启发的一天（one instructive day）
it was sunday afternoon. li ming and i were walking to the park. suddenly we saw a boy fall off his bike. we both hurried to him. since one of his legs was hurt badly, the boy couldn't stand up. he began to cry and we tried to comfort him. we put him on the bike and took him to hospital. the boy got treated at once. i telephoned his parents and told them about the whole story. they thanked us again and again. it was dark then and we said goodbye to them. we felt happy though we couldn't get to the park
