分析：第一段開門見山直接表達感激之情。第二段通過提前準備好一本書以打發旅途無聊時光這一細節，使感激之情更加真摯。第三段講抵達後的情況，報平安，以示關係親近。最後再次表達謝意。

dear tom,
i am very sorry to learn from the evening paper that a tsunami hit（海嘯襲擊） your city this early morning, and i just cannot tell you how sorry i was to learn of your injury. your family tells me that you are progressing nicely（不錯進展）, and that you will be out of the hospital in about ten days. i am certainly relieved to know that!
in the next day or so you will receive a little package from me. i hope you like it, and that it will help to pass the time more pleasantly(和氣地).
with every good wish for your swift recovery.
