Dear friend:
English is very important for many things, bussines, traveling to another country or simply for pleasure, whatever your reasons are, here i give you some ways to improve it.
You can watch tv series or films in english and read some articles on the newspaper.You can also use the internet , there are some pages to learn english. Another way is to talk to people in english, if you live in a country where people don`t speak english you can talk to visitors. Another activity is to write words an phrases that you hear in a book, that will help you to learn more vocabulary.
I hope this helps you with your english and keep practising. Good luck!
