请问上课认真听讲，课后及时复习英文如何写，谢谢！ Listen carefully in class and review timely after class.
要做到课前预习上课时专心听讲课后及时复习用英语怎么写 You should preview the lessons before class，concentrate on the lecture，and go over them after class.
这句话用英语怎么说“学过的知识要及时复习，如果不及时复习就会忘记。” The knowledge which we have learnt needs reviewing in time，or we will forget it.
