Question

翻译并解释句子结构谢谢。

Macfarlane guesses that the fact that water had to be boiled, together with the stomach-purifying properties of tea so eloquently described in Buddhist text.

Answer 1

麦克法兰的猜测，事实上，水，煮，茶如此雄辩地在佛教的文字描述胃净化性能..
个人认为，这两个that引导的都是同位语从句。
第一个that后面的内容表guesses的内容，第二个that后面的内容表the fact 的内容..
