你知道如何更高效地学习吗？

“Be sure to study hard for that test!“要为考试努力学习!” 
How many times have you heard that? But what does it even mean to study hard? Do you have to study until your head hurts? It sounds like it!
听过这句话无数次了?但是到底什么才是努力学习?要学到头疼?听起来是的!
The whole idea of studying harder suggests that you really don’t try very hard as a normal practice, and that is probably not true. So instead of studying harder for better results, you can study smarter, and there is good news: it won’t give you a headache.
努力学习意味着你平常并不把努力当做一回事儿，但事实可能并非如此。因此，除了为得到高分而努力学习，你可以聪明地学，好消息是：聪明地学可不会头疼。How to study Smarter

Some studies on brain science have shown that the practice of revisiting information enhances learning. In other words, it is a good idea to study material more than one time, over a period of days.
有关脑部的研究表明复习有助于强化所学内容。换言之，学习最好不止一遍，要隔几天复习一次。
To study smarter, then, you should start your study session a few days ahead of time and study a few hours, walk away from the material, and study the same material again a few days later.
要聪明地学，就要在计划前几天开始学习，学几个小时，放下学习材料，几天后再看一次。
Learn Through Experience
通过体验学习
There are indications that our brains love to make associations or “connections” when we read or observe something new. It seems that the more we enhance the experience as we read, the more we may retain.
研究表明大脑在我们阅读或观察新事物时喜欢建立联系。这表明，阅读时我们强化的体验越多，我们能记下的就越多。
