下面这句摘自高中英语新教程人教版必学一 p4:
I just had myfirst maths class at senior high school!
请问句中的 at senior highschool 可以换成in senior high school 吗?
可以。句中的 at senior highschool 意为“在高中”,其中的介词也可用in。又如:
She learned toact when she was in senior high school. 她在高中时学过演戏。(《朗文英语写作词典》)
We first met atsenior high school and we’ve been good friends ever since. 大家上高中时开始认识,从此大家就成了好朋友。(《麦克米伦高级英语词典》)
