区别是动词 和名词。例如：如何区别 中国文化 和 美国文化？（动词）
中国文化和美国文化的区别是XXX。（名词）
不同 是形容词和名词：如何区别 X 和 Y 的不同？
不同的中国文化和美国文化常常阻碍人们的沟通交流。
它们做为名词时事可以互换的，可是“区别”更正式，更倾向书面语，来表达概念上的不一样。
有时，它们会在一起用，例如：“区别不同点“
As a professional Mandarin instructor with almost two decades worth of teaching experience in American schools, I came to recognize how language-learning in a school setting is only one step in the long journey of acquiring a foreign language. I felt a need and urge to bring my profession beyond school, and I believe professional teaching should be accessible to anyone at any point in their life. It is with this belief that I founded MAD Mandarin LLC in 2018 with the goal to incorporate the latest teaching methods with my own innovative approach of Mindful-Active-Dynamic to positively achieve the best language-learning results.
