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?
    課上課下
    我們的學(xué)習(xí)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(duì)學(xué)生來(lái)說(shuō)都是重要的，它們互相依存。
    我們必須重視課后學(xué)習(xí)。我們?cè)谡n堂上學(xué)到的東西是有限的，因?yàn)橹荒軐W(xué)到課本上的知識(shí)。然而，課外我們可以學(xué)到更多的東西。重要的是知識(shí)來(lái)源于實(shí)踐。課外學(xué)習(xí)可以讓我們把知識(shí)應(yīng)用到實(shí)踐中去。
    正如課外學(xué)習(xí)一樣，課內(nèi)學(xué)習(xí)也很重要。它占用了我們的大部分時(shí)間，我們必須重視它。課內(nèi)與課外的學(xué)習(xí)緊密地聯(lián)系在一起，它們互相促進(jìn)。
    這樣的話，我們?yōu)槭裁床话阉鼈兘Y(jié)合在一起，有效地學(xué)習(xí)呢?
