This document discusses English sentence structure, specifically the positioning of direct and indirect objects. It covers several types of verbs: (1) verbs like "give" that can take either the pattern "verb direct object to indirect object" or "verb indirect object direct object"; (2) verbs like "ask" that only use the pattern "verb indirect object direct object"; and (3) verbs like "explain" that only use the pattern "verb direct object to indirect object". It provides examples and exercises for learners to practice forming sentences using these different verb patterns.
