How to Study Efficiently
As students, we have to study almost every day. However, not everybody knows how to study efficiently .The above graph helps us know better about it.
作为学生，我们差不多每天都要学习。然而，并非每个人都知道如何有效地学习。上面这个图表能帮助我们更好地了解这个。
This graph shows the relationship between the study efficiency and the hours spent in studying in a day. From it, we can see that more hours of study do not necessarily result in better or higher study efficiency. In the graph, the optimum of efficiency comes when one studies about 5 hours and the efficiency begins to drop as he studies longer than it. By the time when one studies 11 hours per day， his efficiency of study becomes very poor.
该图显示了学习效率和一天中在学习上所花费的时间之间的关系。从图表中我们可以看到更多的学习时间不一定会产生更好或更高的学习效率。在图表中，当一个人学习差不多5个小时的时候，将产生效率的最佳值，当学习超过这个时间的时候，效率开始下降。当一个人每天学习达到11个小时，他的学习效率会变得非常低。
In conclusion, there is always a maximum of efficiency and an appropriate amount of time for study in a day. More time spent in study doesn't always mean greater efficiency.(137 worrds)
总之，一天的学习中总是会有最大的效率和适量的时间。花更多的时间在学习上并不总是意味着会有更高的效率。
