Thanks for the explaination.

3. verb+ing form of verb.
generally after comma (verb+ing) form comes and it modifies the whole clause preceding it. But i dont understand how does it modifies? somewhere i read that it modifies the action of the preceding clause and subject of the preceding clause becomes the subject of verb+ing. can you please elaborate?

Also sometime i become confused when to use verb+ing form and when to use infinitive (to+verb) form in a sentence.

please explain?

Thanks
