先当学生听别人讲，再当老师给别人讲，这是一种有效的学习方法。
It is an effective way to learn that students listen to others first, and then teachers tell others.
爸爸平时工作很忙，很少有时间指导我的学习，他今天忙里偷闲，和我一块复习《社会》这门功课。我先听爸爸讲了一次《多种多样的商业场所》。爸爸先讲了如何从题目推想内容，他说一看题目就应该知道里面讲的是商业场所，而商业场所又是多种多样的。接着爸爸给我分析了课文使用的先总后分的写作方法：教材先总的说了我们周围有不少商业场所，然后又具体从百货商场、超级市场、便民店、专业店、农贸市场、集市说明市场是多种多样的。（我心中暗想：这种先总后分的写作方法在以后的作文中也可以学习呀！）爸爸还说，我们不仅要做到打开书一看就会，更要做到合住书一说就对。
My father is very busy at work and seldom has time to guide my study. Today, he is very busy, and I will review "society" together. First, I listened to my father's talk about a variety of business places. Dad first talked about how to deduce the content from the topic. He said that when he saw the topic, he should know that it was about business places, which were various. Then my father gave me an analysis of the writing method of using the text from the beginning to the end: the textbook first said that there are many commercial places around us, and then explained that the market is diverse from department stores, supermarkets, convenience stores, specialty stores, farmer's markets and markets. (I thought to myself: this kind of writing method can also be learned in later compositions.) Dad also said that we should not only open the book and read it, but also close the book and say it right.
爸爸讲完后，又要求我当一回小老师，让我把刚才复习的内容给妈妈讲一次，以加强记忆。在我给妈妈讲的过程中，我发现我对这些知识竟然大部分都掌握了，当然同时也发现仍然有一小部分需要进一步加强。 别人讲，使我加深了对课文的理解；而自己给别人讲，又不仅锻炼了口头表达能力，也同时使我加强了对知识的记忆。
啊，先当学生听，后当老师讲，这真实一种好的学习方法呀！
Ah, it's a real good way to learn, first as a student, then as a teacher!
