如何保持娱乐和学习之间的平衡 英语短文
答案
the balance of entertainment and study
people always believing that study and recreations are like water and fire .they can not be combine together .but in my opinion ,the can .even on the contary they are relations.
all work and no play make Jack a dull boy .the idiom tell us a very simple meaning,but how to master the deep meaning need a clear aim.no one can bear much press and not pour it out.If he or she does it .the side effect will come into being.for example.if you have lots of things to do and they all will meet the deadline soon.what you need to do is to improve your effciency.A clear mind is essential.so what we should do is to make our minds work steadily and sustainably .you can take a break after one or two hours work.and try to do something else like chatting with your friends and talk the jokes if the work need to be done very carefully and be finished on time like a test practice.
