There are many optimistic(乐观的)people around us. 1 person I have ever seen is my dad!He is so positive that I have never heard 2 single word from him which is related to hopelessness!Unlike most mums and dads,my dad never says things that 3 make me feel sad. He is always there to give 4 encouragement and help. When I do something wrong,he always tells me 5 I should do next time in a positive way. For example,if I am 6 trouble,he often tells me to open the books he has bought for me. Then he asks me 7 the stories that can help me with the problems I'm facing. After that,we will have a discussion together. If it's useless,he 8__ me calm down firstly and think about what happened to me by myself.9_ I'm not always a good kid because of my naughty character,my dad never shouts at or gets angry with me. I know that he's waiting for the day when I grow up and understand some important things in my life.I can see the reason why he is so positive is that he believes in himself,and also I __ 10 __ by him.
