You can download some news such as BBC and VOA first and listen to it every day at first (if you don't have time during the day, you can also listen to it before going to bed at night). It doesn't matter if you don't understand it at first. Force yourself to listen, and gradually feel that the speed of speech is not so fast. Then try to listen to what you hear and say, and then try to dictate sentence by sentence, which is very helpful to improve your listening.

If you think the news is too boring, you can download some English songs, movies and so on. The same method is very useful.

Of course, we should also increase our vocabulary, download some software to remember words, and remember more words.

Besides, you should dare to speak. When the above two listening and vocabulary have been greatly improved, you can practice your spoken English on some English chat and dating websites such as facebook.

Finally, try to write your usual feelings or diary in English.

So everyone is practicing listening, speaking, reading and writing. Start with what interests you and take your time. You will like English more and more. If you are interested, you will learn it well! I wish you success ~
