Hi Kenny, I have replied to your email.
Your message:
But how do i learn english? Do i start to learn grammar first? and how do i learn new words (write the words in my notebook and try to study them?)
Is this a good method? I think i will forget the words if i do this
You need to begin learning the correct grammar start with the basics and work through it, with good resources and grammar help with exercises, as with all languages you need to practice and study it. This is a good method but you will need to use a dictionary for you to understand what the words mean.
If i read a lot of books in english, will my english skills increase [improve]
And if i watch english films...
Reading and watching materials are a very good source for learning english but as i said above you need to know what the words mean and how to use them etc. There are lots of grammar, reading, writing exercises available so you can use these to help you understand and start learning basic phrases.
For example start to write sentences about yourself and then read this aloud and practice, practice, practice. There are lots of audio files and resources that you can use to help you with your pronounciation etc. If you can pay for lessons this would be the best advantage for you, getting practice with a native speaker is the best way to really understand and learn english.
What do i have to do so that my english would be nice in 1-5 years?
If you do all the above there is absolutely no reason why you should not learn english within your time span. With determination and practice you will succeed.
Take care
Kelly
