错误的句子：只有你来了，我们吃饭。A
只有遵守三个条件的一个，就可以玩游戏。B
正确的句子：只有你来了，我们才吃饭。A
只要遵守三个条件中的一个，就可以玩游戏。B
错误的原因：这两个词组都是固定搭配，不可省略（A），或者混搭（B）。
另外，这两个词组的意思是不一样的：只有···才··· （Only if ······）；只要···就··· （Once if······）
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.
