△ Introduce Zhao Zhouqiao, first write the history (ancient construction time, long service time), structure, shape, design and construction characteristics, then explain it in detail in four points, and then end with an evaluation sentence ("Zhao Zhouqiao's high technical level ..."). In this way, the total score is used in the paragraph, which makes the introduction very organized.
