Find Some Friends
There is nothing like having a few friends to study English together. You can practice the exercises together, have conversations together (in English!), and, as you study English together, help each other with exercises you may not understand.
没有什么比得上和几个朋友一起学习了。你们可以一起做练习，一起对话(用英语!)。当你们一起学习英语的时候，可以针对不懂的练习互相帮助。
ChooseTopics that Interest You
One of the most important things to do is to study English using topics that you like. This will help motivate you because you will also be learning about a topic you find interesting while you study English.
重要的一点就是，选择你喜欢的话题来学习英语。这样可以使你激发动力，因为你是一边学英语，一边学习你感兴趣的话题。
