求翻译：在上课之前把要学习的知识预习一下，上课时就可以有重点的听了，这样上课也不会觉得累，不是吗？在课后除了做作业巩固知识以外，还要学会问问题，多问几个问什么，然后积极的寻找答案。是什么意思？

Knowledge to learn preview before class, the class can focus on listening to, this class will not feel tired, do not you? In addition to homework to consolidate knowledge in the after school, but also learn to ask questions, ask a few more to ask what, then find the answer.
