Studying for exams! Please help! What are two rules of Subject-Verb agreement?

In English, questions of subject-verb agreement occur only in the present tense, except for the past tense of "to be." In the present, if the subject is a singular noun or a singular third-person pronoun, the verb ends in s. If the subject is anything else, the verb has no ending. The past tense of "to be" is "was" (singular) or "were" (plural). ("You" is always treated as plural even when it refers to only one person.) A verb agrees with its SUBJECT, which is not necesssarly the noun or pronoun just before it. if you have trouble being sure which noun or pronoun is the subject, identify the verb and ask yourself, "Who or what does this?" Ex.: The members of that church are going on a pilgrimmage. (subject: "members") The man who sent Susan those flowers wants to marry her. (subject: "man") If two singular subjects are joined by "and," the verb should be plural--no s. If two subjects are joined by "or" or "nor," the verb agrees with the closer subject. Ex.: Megan and Grace go to the same school. Neither the police nor the fire department was notified of the explosion. Either Sam or Charlie has my book. Is this enough?
