There is no knack to learn English. I think that you should try your best to communicate in spite of making some mistakes, and read more books about grammar (it’s very helpful for an English beginner); and then, reading some interesting stories written in English, chatting with foreigner on the internet. In this way, you will make your English a big progress.
学习英语没有什么诀窍,我认为你应该尽量的多交流不要怕犯错误,多读一些语法书(这对初学都很有用);然后,读一些用英语写的有趣故事,在网上和老外聊聊天。这样,你的英语会有很大的进步。
