It is nearly three years since I studied in senior high school. I'm glad to\rshare with you my experiences at school.\rI study very hard here and have learned much knowledge, which makes me very happy. Most\rexcitingly, I've made great progress in English. I am not good at physics, so I'll have to work\rharder in the future.\rIn this school, I have made so many friends that I never feel lonely. In my spare time, I\roften participate in a variety of after-school activities.\rWhat about your school life? I'm looking forward to your early reply\rYours,\rLi Hua
