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.
个，位，口
这三个量词都可以和“人” 有关，比如：一个人，一位老师，一口人。可是，它们很多并不可以混用，不可以说：一位人，一口老师。
记住下面三点可以帮你区别它们：
“位” 通常形容人的职业，职位，或社会身份：一位老师，这位总统，三位客人，那位先生，等等。给人比较正式的感觉。
“口” 通常只用在介绍家庭成员，比如，“我家有五口人。”
“个” 是个“万能(all purpose)”量词，在这里，它可以取代 ”位“ 和 ”口“，而听起来没有错，比如：一个老师，一个人，一个总统。可是表达的意思就会有些不同。比如：”一位总统“ 比 ”一个总统“ 听起来更正式并有敬意；”一口人“ 比 “一个人” 更精确的表达家庭的人口数量。
这样说对你有帮助吗？
