our tudy can be pided into two part: one i in cla and the other i out of cla. both of them are important to tudent. they depend on each other.
we mut attach importance to after-cla what we have learnt in cla i very. limited, becaue only knowledge in tetbook can be acquired. however, we can learn more out of cla. a mot important thing i that knowledge come from practice. in the after- cla tudy we can apply out knowledge to practice.
jut iike after-cla tudy, tudy in cla i alo very important. it occupie mot of our time. we mut pay much attention to it. in-cla tudy and after-cla tudy are cloely connected with each other and improve each other.
if that the cae, why dont we combine them and tudy effectively?
