This document provides examples and instructions for varying sentence structure through different techniques: - Beginning sentences with prepositional phrases to add variety. Short prepositional phrases may not need commas. - Using compound predicates containing more than one verb to combine two simple sentences with the same subject. - Joining ideas with "-ing" modifiers by converting the first verb to "-ing" and dropping the subject to indicate simultaneous actions. - Combining sentences with past participial modifiers by changing the first sentence into a past participle that introduces the second sentence.
