Hi
I am an English trainer. I fully agree with Priyen that reading anything interesting aloud is the best way to learn any language. After a week's reading you must start a process of identifying and underlining the helping verbs like "is, are, am, was, were, will, will be, would, should". These are the basic necessities in sentence formations. Then comes subject word agreement which is equally important. You have lots of comphrehension lessons in google too. try them later. Good luck.
