Study in Class and out of Class

　　Our study can be divided into two parts: one is in class and the other is out of class. Both of them are important to students. They depend on each other.

　　We must attach importance to after-class What we have learnt in class is very. limited, because only knowledge in textbooks can be acquired. However, we can learn more out of class. A most important thing is that knowledge comes from practice. In the after- class study we can apply out knowledge to practice.

　　Just Iike after-class study, study in class is also very important. It occupies most of our time. We must pay much attention to it. In-class study and after-class study are closely connected with each other and improve each other.

　　If that' s the case, why don't we combine them and study effectively?

　　我們的學習可以被分成兩部分：一部分在課堂上，另一部分在課堂外。這兩部分對學生來說都是重要的，它們互相依存。

　　我們必須重視課后學習。我們在課堂上學到的東西是有限的，因為只能學到課本上的知識。然而，課外我們可以學到更多的東西。最重要的是知識來源于實踐。課外學習可以讓我們把知識應用到實踐中去。

　　正如課外學習一樣，課內(nèi)學習也很重要。它占用了我們的大部分時間，我們必須重視它。課內(nèi)與課外的學習緊密地聯(lián)系在一起，它們互相促進。
