有同学问我，“做错” 和 “做错了” 哪个对？
这两句话都对。 “做错“ 是广东话的表达，而”做错了“是国语的表达。 换言之，在这里，表达同样的意思时，国语会加一个”了“。
源自宋老师《别样学中文》
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.
