Please I want you to help me with some advices because everytime I sit down to read I have to read twice or three times any articles in order to understand the meaning
That could be because you're just starting.
When I read my first "real" English book, I could probably understand one or sentences a page. With practice, it got better and better.
There's a lot of questions as to how to become better in this or that in English but there's no secret. It's just like anything in this world:
Sacrifice time to it, practice times and times again.
Don't try to understand every single word. Just go for the main idea of each paragraph.
