Subject-Verb Agreement
o The subject of a sentence is what the
sentence is all about. In the following sentence, the word "book" is
the subject: "The book is on the table." In this example, the focus
of the sentence is the object in question: the book that sits on the table's
surface.
o The verb of a sentence is the action
word that generally describes what the subject is doing. In the following
sentence, the word "walks" is the verb: "The man walks to the
car." In this sentence, the verb "walks" describes what the
subject "man" is doing.
o In all English sentences, both the
subject and the verb must agree with one another. Depending on whether or not
the subject is singular or plural, the verb must match that subject(s) and/or
object(s) accordingly. For example, if the subject of the sentence is singular
("the man") then the verb that describes what the man is doing must
also be singular ("is," "sits," "eats,"
"smiles," etc.). If the subject is plural ("the men"), then
the verb that describes the subject should also be plural ("are,"
"sit," "eat," "smile," etc.).
EXAMPLE :
1. Skating IS becoming more popular
