　　Dear Mrs Jenkins，

　　I’m Li Hua, a student of Mick’s class. I’m extremely sorry to tell you Mick is in hospital. On August 10, some classmates and I invited Mick to take a bike trip. On the way back, he fell off his bike unfortunately and had his leg broken.Immediately we took him to our local best hospital. After a CT scan, the doctor said his leg injury was a bit serious and that he had to be treated for over a month.

　　Fortunately, he has the insurance to cover the medical costs. Please don’t worry about him since we are taking good care of him every day.

　　Regards，Li Hua
