Dear Mike, 　　 From the TV I know many A/HINI I flu cases are reported recently in the United States and many schools are closed as a result. I’m so worried about you. Are you alright? Are there any A/HINI flu cases in your school? Do you still have to school everyday? 　　 To stay away from the disease, you’d better stay at home as much as possible and not go to places where there are many people. Wash your hands more often to keep them clean; Open the window to have more fresh air in the room; And eat more fruit and vegetable to keep yourself fit and strong. 　　 So far the disease is not so deadly as it seems to be. Do be at ease! Take care and you’ll be OK.（英語作文） 　　 Yours truly, 　　 Li Hua
