One possible version:
Dear Tom,
Recently, while browsing a senior high school website of New Zealand, I saw the message you posted on it. I get to know your wishes that you intend to travel in Beijing during the summer vacation with a Chinese student as your guide.
Learning this news, I am really willing to travel with you and introduce Beijing to you. I know as a brilliant guide I am supposed to make your journey interesting and meaningful. For one thing, I will keep you company visiting numerous great places of interest and enjoy the wonderful sightseeing. For another, I am going to tell you the long and rich history of Beijing.
I am looking forward to the reply from you. With all my wishes you could give me this honor.
Yours sincerely,
Li Hua
题目分析：本文根据要求和内容来看，包括：1.希望做他的导游；2.打算如何给他做导游；3.期盼他的回复。要用不同的时态表述。应用第一人称的语气表达。还应该注意使用较高级的词汇和句子的衔接，以提高作文的档次。字数要求100词左右。
【亮点说明】文章结构清楚，层次明确。使用了For one thing，For another,来说明自己做导游的优势。另外用了am supposed to，keep doing，还运用了-ing形式作状语，looking forward to；定语从句、同位语从句等短语和较为复杂的表达。
