Do anyone know where can i get more information about the structure of the sentences? For an example, in a statement like John kick the ball. Noun+Verb and so on. something like what plus what.
If you need general info on sentence structures, you could check http://www.ucl.ac.uk/internet-grammar/
Perhaps it's somewhat advanced for you, but you'll find some useful information there.
If you're looking for a grammar checker, I'd advise you to avoid such a thing. Structure of English is overly complex for a simple web-based program to handle.
Take MS Word for instance...
