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 like 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?

我們的學習可以分為兩個部分：一是在課堂上學習和一個是課外學習。它們都是很重要、彼此依賴的。

我們必須重視課外學習，我們在課堂上學到的東西是非常有限的，因為只有在教科書可以獲得知識。然而，我們課外可以學到更多，最重要的是知識來源于實踐。在課后學習中我們可以把知識應(yīng)用到實踐。正如課外學習那樣，課堂中學習也很重要，它占用了我們的大部分時間，我們必須重視它。在課堂學習和課外學習相輔相成、相互促進。

如果那樣的話，為什么我們不把它們結(jié)合起來更有效率的學習呢？
