Hello, and welcome to the Peterson Museum of Natural History. My name is Sarah and I will be your guide today. Before we begin, I’d like to remind you not to touch any of the exhibits, as many of them are fragile and cannot be easily replaced. Also, if you need to use the restroom, they are located by the entrance to the museum.
Our first exhibit is the dinosaur hall. As you can see, we have a variety of dinosaur skeletons on display, including a full-sized Tyrannosaurus Rex, which stands at over 40 feet tall! We also have a number of interactive touchscreens where you can learn more about each species.
Next, we have the Hall of Mammals. Here you will find exhibits showcasing the diversity of mammals around the world. We have everything from tiny rodents to massive elephants on display. You can also learn about the evolution of mammals and their various adaptations.
Our final exhibit is the Earth and Space exhibit. Here you can learn about the formation of the solar system, and the various planets and moons that make it up. You can also explore the history of Earth, including the impact of human beings on our environment.

3. 百度经验文章格式
1. 标题：文章主要内容，起到引导作用。
2. 简介：简单介绍文章内容，让读者对文章有一个初步的了解。
3. 正文：结构要清晰，段落要分明，需要有承接、转换等过渡语词，文章内容要具体，有例子作为佐证，能够吸引读者的注意力，同时争取说服读者。
4. 结论：总结全文主要观点和内容，总结思路要清晰，结论要有实质性的内容，重点提炼本文中所讲述的核心观点。
5. 参考文献：如有，需注明出处，避免抄袭。
4. 段落建议
1. 开门见山。首段的目的是引发读者兴趣，让读者想继续阅读下去。因此在文章的第一段尽量展现出本文的重头戏，吸引读者的兴趣。
2. 分段。 这是整篇文章的基础，也是读者阅读的依据。建议每个段落都有一个中心思想，遵循主题思考，语言表达简洁明了，段落要语义紧密，不要过长和过于简短。
3. 段落残留。 建议每个段落最后都有一个总结性的语句，这样可以让读者更好的理解本段的中心思想。并且可以打破文章内容单调的节奏，带动整篇文章的节奏。
4. 逻辑紧密。文章应当有一个逻辑顺序，段落之间应当考虑过渡。例如：在上一段回顾了前段讲的内容后，可以用一个句子作为过渡来引入下一个段落。这样能让文章内容更通顺，也便于读者阅读。
