My daughter was in Grade 10 in high school.Her life had been followed by her dyslexia ( 阅读障碍 ) . She battled with her schoolwork and her teachers in high school.Her math teacher, seemingly the only teacher who understood and empathized with her dyslexia, unexpectedly offered to read her the questions in a math exam.As a result, she got a previously unheard­of B for math.The act of one thoughtful teacher had, perhaps for the first time in my daughter ' s public life, made her heart open to enjoy life to the full, and she could now start to believe in herself and her abilities. I could of course want to contact and thank the math teacher.I phoned the school and when I asked to speak to the math teacher, I received a very guarded “why” from the receptionist who had long been the gatekeeper, fending off ( 抵挡 ) angry parents for teachers.The surprise in her voice was obvious when I replied “I want to thank him” .“ Oh ...of course, just a moment , ” she responded.The teacher came on the line with the same sense of caution, knowing only that a parent was on the line.I said, “ I just want to thank you for reading the questions to my daughter for her math exam.Not only did she get a B but you have no idea the positive impact your action has had on my daughter ' s self­belief and hopes for her future. ” My daughter ' s struggles with dyslexia continue to this day.However, she is now an experienced fully­qualified worker who believes in herself and has helped many people in Family and Youth Care Organization.Doing something positive to help a person will make you feel good.Of far greater importance, however, it might change the life of the person you helped and, through his/her renewal, impact positively on the lives of hundreds of other people.
