选C
work hard at,固定词组搭配,努力工作(学习)
希望对您有所帮助~确定么。。课本里可是at和in混着用的。。一会是you are too busy at school一会又是you work hard at school。。可以保证么。。大侠。。at school,是表地点的地点状语。at不是跟前面的和be busy或者work hard连用的= =you are too busy at school表示“你在学校很忙”。但是并没有说忙于干什么。be busy with sth,忙于某事;忙着做,可以说,you are too busy with study at school。这里就是说,你在学校忙于学习。突出的是忙着做的事情。be busy doing.you are too busy learning English at school.这里的意思就是,你在学校忙于学习英语。这里就更具体了。work hard也是一样的。
