we clean the classroom every Friday afternoon.的句子成分为什么不能说we clean the classroom in every Friday afternoon或we clean the classroom on every Friday afternoon或we clean the classroom at every Friday afternoon为什么?时间状
in是特指,是固定的时间或地点,every是泛指,例如,i clean my room every morning,如果用in,就是i clean my roon in the morning,是确定的时间.
可以说in the afternoon.
every friday afternoon就是泛指每个周五下午了，你如果再加上in不是画蛇添足了吗？
on是特指某一天
至于at，根本没这说法，一般用语时间，几点钟
有些英语就和中文一样，久而久之习惯了有些地方就不会去追究为什么了，其中也不是什么考点，当做固定搭配来记就好了，出现这个问题大概是因为阅读得少，语感不够强，所以才会觉得为什么用这个对用那个也对的情景.
不用加介词，因为这里是时间状语。
