This document discusses the differences between gerunds and infinitives in English grammar. It explains that gerunds are verb forms ending in "-ing" that can function as nouns, while infinitives use the word "to" before the verb. Certain verbs can be followed by either a gerund or infinitive, while others prefer one form. Examples are provided of common uses for gerunds and infinitives. An exercise asks students to fill in sentences with the correct gerund or infinitive form based on the preceding verb. The document was created by an English teacher to teach these grammar concepts.
