We have classes on Thursday afternoon.为何用on
这里为什么要用on 星期前要用on没错 ,可是后面还有个afternoon啊?
而且也没说具体哪天的thursday afternoon.
我觉得是不是答案错了应该选C
A.in B.at C./ D.on

Thursay 就是具体到那天了.只要是几月几日或者星期几都是具体的
如果是 in the afternoon 就不是具体的时间了.
再问：谢谢可是这个选择题不严谨啊你发现了吗？我觉得其实不填读起来更通顺
再答：很严谨啊，是你理解有误。
再问：我理解的是 Thursday前省略了this呵呵
再答：如果用this，就该用将来时或者过去时，就不是一般现在时了
