How to improve your English standard
To learn a foreign language, the most important point is to practise often.
You must read English newspaper, books and stories regularly so as to set your mind in an English environment. Furthermore, when you come across any vocabulary that you don't understand, check the meaning out from dictionary and remeber the new word.
In your readings, try to memorise how the sentences are structured and how the correct grammar is used. Don't be afraid to talk more with English speakers and listen to how they use some slangs / native phrases.
Nowadays, it is easy to access English web sites online which helps to keep you updated on new words / phrases that are used by people. I suggest you also keep a habit of writing English diarywhich gives you frequent practice of using the Englis language.
If you can keep the above methods in mind and do them frequently, I guarantee your English level will improve within a short time.
