给你的朋友Tom写一封英文信，假设他上个月给你在纽约预订了一间双人房间，并为你在纽约旅行时做向导（guide），为你提供了很多帮助，所以你特地写信向他表示感谢。注意英文书信的格式。(字数不少于100字)

英文信件的格式大概就是这样：首先是称呼，然后再问候语，正文，再结尾。以下供参考：Dear Tom,Good day!This is XXX, I'd like to thank you for your help when I was in New York last month。 You're so nice a person。 You booked a room for me and show me around。 With your help, I had a wonderful time。 Whenever you come to China, please let me know。 It will be my pleasure to be your guide。 By the way, please say hello to your family for me。 Thanks again and looking forward to hearing from you。Faithfully yours/ Best regards,XXX。
