Subject Verb Agreement

This topic is really a hard one to memorize because there are so many Rules to understand and all of them really differs from one another. each rule represents a certain kind of sentence.

A singular subject takes a singular verb, whereas a plural subject takes a plural verb, is the most basic rule.

Rule 1. A subject will come before a phrase beginning with of. This is a key rule for understanding subjects. The word of is the culprit in many, perhaps most, subject-verb mistakes.Rule 2. Two singular subjects connected by or, either/or, or neither/nor require a singular verb.Rule 3. The verb in an or, either/or, or neither/nor sentence agrees with the noun or pronoun closest to it.Rule 4. As a general rule, use a plural verb with two or more subjects when they are connected by and.

Rule 5a. Sometimes the subject is separated from the verb by such words as along with, as well as, besides, not, etc. These words and phrases are not part of the subject. Ignore them and use a singular verb when the subject is singular.

Rule 5b. Parentheses are not part of the subject.

Rule 6. In sentences beginning with here or there, the true subject follows the verb.

Rule 7. Use a singular verb with distances, periods of time, sums of money, etc., when considered as a unit.

Rule 8. With words that indicate portions—e.g., a lot, a majority, some, all—Rule 1 given earlier in this section is reversed, and we are guided by the noun after of. If the noun after of is singular, use a singular verb. If it is plural, use a plural verb.

Rule 9. With collective nouns such as group, jury, family, audience, population, the verb might be singular or plural, depending on the writer's intent.

There are many more rules that can supply the explanation that you need in a certain sentence and can help you create a sentence that is grammatically correct. 

Yes it is indeed hard to memorize but this set of rules can really make a huge difference in your sentence writing.
