Text structure refers to the way information is organized in a written piece. It helps readers understand the main ideas and how they relate to each other. Common structures include chronological order, where events are presented in the order they happen, and cause and effect, which shows how one event leads to another. Understanding text structure is important for effective reading and writing. It allows readers to follow the author's thoughts more easily and helps writers present their ideas clearly. By recognizing structures like compare and contrast or problem and solution, readers can better grasp the content and its purpose.
