(A) All verbs except modal verbs agree in person and number with their subjects.

e.g. I play basketball every Sunday.
    He plays basketball every Sunday.
    The pictures are beautiful.
    The picture is beautiful.

(B) When the subject is qualified by a phrase, we must take care that the verb agrees with the subject, not with the noun or pronoun in the phrase.

e.g. The building with big windows is a public library.
    The windows of this room are dirty.

(C ) We use a singular verb:

i. when two subjects are linked by 'and' but express one idea.
e.g. Bread and butter is my favorite breakfast.
    The famous composer and singer is in Hong Kong.

ii. after 'the number of'
e.g. The number of millionaires is increasing.

e.g. Many a man has run away.
Compare: Many men have run away.

e.g. The police are hunting for the suspect.

ii. when 'the + adjective' represents a category of people.
e.g. The rich are not always happy.

(E) We use either a singular or plural verb in the following situations:

i. when two subjects are joined by with, together with, along with, as well as, including, in addition to, like, rather than, etc., the verb agrees with the first subject.
