Verb Overview The official names of the tenses are not important for the ACT/GMAT/GRE/PSAT/SAT. What is important is knowing the proper structure to have the correct verb tense to express what you are doing. Subject-Verb Agreement o Verbs must agree with its subject noun in person and number: Singular, add an “s”; plural, no “s.” o The noun closest to a verb may not be its subject. o Even if there are 2 (or more) subjects, only “and” makes it compound and plural. Infinitives are verb forms that are preceded by the word “to.” o E.G., I want to swim in the pool. Gerunds are verb forms that end with “–ing” and act as nouns. o E.G., I enjoy swimming. Participles are verb forms that act like adjectives. o Past Participles have happened in the past—they use the simple past tense form of the verb, which is usually, but not always, “-ed.” E.G., The whispered word. o Present Participles operates in the present—they use the “-ing” form of a verb. E.G., The house has a swimming pool. o Future Participles don’t exist in the English language.
