【答案解析】Dear David,
I was really shocked and saddened to hear of your unhappy experience in the typhoon. There is little that anyone can say or do at a time like this to ease your grief, but I would express my deepest sympathy.
In the next day or so you will receive a little package from me. I hope you like it, and that it will be useful at your present moment. What"s more, please don"t hesitate to contact me if there is anything else I can do now and always.
I do hope you will soon get well again and be able to come back to school. Be assured of my availability and eagerness to help in any way I can.
