信守诺言

我给好朋友承诺了，以便更顺利地沟通、更快乐地享受将来在一起的生活，我一定要努力提高中文水平的时候以来，已经过四年了。对不起，亲爱的朋友。这四年中，我没有认真地锻炼过我的能力。从今天开始我要继续努力好好学习的。虽然我们不再联系了，我希望你一切都好，满心感谢你以前一直耐心地鼓励我。

Four years have passed since I last promised my good friend that in order to communicate more smoothly and enjoy more our future life together, I will work hard to improve my Chinese. Dear friend, I'm sorry. These last four years, I have not exercised my abilities earnestly. Starting today, I will continue to work hard and study properly. Although we're no longer in contact, I hope all is well with you and thank you from the bottom of my heart for always patiently encouraging me in the past.
