2 A gerund is: a verbal (a verb form used as another part of speech). a verb form ending in -ing used as a noun. It can be in the position of subject, direct object, object of the preposition, or predicate noun.
3 Examples: Subject - Reading is my favorite activity. Direct Object - I enjoy reading.Object of the Preposition - Rainy days are good days for reading.Predicate Noun - My favorite subject is reading.
4 The subject of a sentence is the person, place, thing, or idea that is doing or being something. A direct object follows an action verb, and answers the questions who or what. The direct object receives the action from the subject. It must follow an action verb, not a verb “to be” (am, is, are, was, were, be, become, became).
5 Prepositions are words which begin prepositional phrases such as for, on, in, by, about, to, etc. The object of the preposition is the noun that follows a preposition.A predicate noun follows a form of the verb “to be.” A predicate noun renames the subject of a sentence.
6 Remember this: Do these steps: A word ending in -ing can be either a verb, a participle or a gerund. To determine which one it is, you must determine how it is used in the sentence.Do these steps: Find the simple subject and simple predicate (verb). If the -ing form of the verb is not part of the simple predicate (verb), then determine how it is used in the sentence. Is it in a noun position? Then it is a gerund. If it is used as an adjective, then it will be a participle.
7 Examples:Bill and Tony are running. are running is the verb in this sentence.Bill and Tony enjoy running. running is a gerund, a direct object of the action verb, enjoy.The running water overflowed. running is a present participle (adjective) modifying the noun, water.
