参考作文地带整理范文：

Dear Sir/Madam,

Greetings from China!

This is Li Hua, a student in China. I’ve been fond of pandas since my childhood. Since three years ago, when the panda Baiyun gave birth to her baby panda Sulin, I have been visiting your website to keep myself informed about how things are going for them. Knowing Sulin will turn three soon, I want to say happy birthday to her and express my thanks to all of you for your such good care for it, with which she has been brought up and has been living happily with her parents in the US.

我是李华，一位在中国的学生。我从小就喜欢熊猫。自从三年前，当熊猫白云生下她的宝宝熊猫苏林以来，我一直在访问您的网站，让自己了解它们的情况。我知道苏林很快就要满三岁了，我想向她说生日快乐，并感谢你们所有人对她的照顾，她一直与她在美国长大并幸福地生活在一起。

By the way, I wonder if I could have a photo taken of Sulin on her third birthday. Thank you very much in advance.

顺便说一句，我想知道我是否可以在苏琳三岁生日那天拍一张照片。非常感谢你。

Yours truly,

Li Hua
