Dear Parents, (注意格式：非冒号，是逗号)

    I am writing this letter to express my thanks to you, because I made a memorable achievement in recent English Speech Competition.

    During my high school study, I had a variety of difficulties in English learning. For instance, I had great trouble memorizing words. In addition, it was also difficult for me to understand the rules of grammar. Though I could write and read, I could not express myself freely in oral English. Then, you encouraged me to participate in the English Club. Gradually, I am convinced that practice makes perfect. It is constant practice that enables me to build up adequate knowledge, skills and competence about making speech in English. Finally, I succeeded in this competition. Your encouragement brings me power, arouses my enthusiasm for English and helps me to make progress every day.

    As your child, I am convinced that suppose I intend to achieve greater success in future, it is advisable for me to set a greater goal. I deem that if I try my utmost to do everything, the future of my life will be hopeful and promising. Thanks again, my dear parents!

                                                                                                                  Yours Sincerely

                                                                                                                    Sky
