【答案解析】
Dear Jimmy,
I was sorry to learn that you were injured in a car accident. I am writing at once to express my deep sympathy in your injury.
It is understandable that you may now feel it"s unfair for you. For one thing, it was not your fault to have caused the accident. For another, the offender has been a hit-and-run driver so far and the police are still looking for the clues. However, we should believe that justice has long arms. Therefore, I do hope you can cheer up and take good care of yourself.
I shall go to see you as soon as I come back from my bussiness trip. Again, sorry for your misfortune, and I am anticipating your speedy recovery. With my heartfelt concern and best wishes!
