求大神讲解一下这段英语里的所有语法，包括句型和短语等，急

Question

What is funny in one culture might not be in another, due to a lack of shared knowledge about history, current events, traditions and customs.

Answer 1

What is... 是what引导的主语从句，due to的to是介词，后面只能跟名词，所以跟history, events等等。这是新概念3里面one man's meat is another man's poison那课里面的吧hhh求采纳！
