How to improve reading skill in English!

[Van Noeurn]

Dear English forum
i have a lot of problems with reading and i cannot read efficiently. Any time i read i always face a lot of difficulties including vocabulary, structure, slang and idioms.
Furthermore, some reading relating with skill, which i do not understand sense.

Are there any methodology that i can use to find out the way to improve my reading?

Thanks

My best regard
