特别感谢大卫为我写这篇文章！拜托帮我翻译成英文

先来翻译你上面句子
Thank you very much for your kindly writing this article for me!
这样表达意思足够
还可以用更高顶级的表达感谢的句子

I wish there were a better word than "thanks" to express my gratutude for your writing this article for me.
我希望有一个词，比“谢谢”更好，用来来表达我对你谢意！
----
相信我 欢迎私下交流

论文：根据你的语境，用paper比较确切；一般的SCI的致谢（acknowledgement）一般都是这样写的。

Special thanks are given to David for his writing this paper for me.
