“去” 和 “上” 和时间词结合在一起，都是表达过去的某个时刻。可是它们是固定搭配又变化无常，所以常出错。
错误的句子：我上年去了中国。我去星期来到了美国。
正确的句子：我去年去了中国。我上星期来到了美国。
错误的原因：固定搭配，不可随意挑换。
解决的办法：背下来。今天背三个常用的：去年，上星期，上次。
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.
