The basic rule takes into account the form of the Subject:
A singular noun/pronoun as a subject requires a 3rd person singular verb.
ex. A bird is flying over...
This was my story.
Jack has arrived...
Exceptions: news, mumps, mathematics (all take a singular verb) and so on.
The agreements gets a little tricky when it comes to collective nouns:
ex. The Cabinet are meeting today = all the ministers and secretaries of state
or
The Cabinet is nothing but a bunch of incompetents = the Cabinet as a whole.
