UNIT 5 课时跟踪检测（三） 阅读写作融会练 Ⅰ.阅读理解 An interactive map was published by the tourism website Smoky Mountains. It is intended for fall foliage (枝叶) fans. It will help them make the most of the colorful season. The map draws on various data. It includes rainfall and temperature forecasts. It includes average daylight exposure. It predicts the timing of leaves' color change across the United States. Users can view weekly forecasts. They select date, which are listed below the map. Shades of green overtake the map when users click September 7. Shades of orange, red and brown appear by October 19. They indicate the arrival of near peak or peak foliage in the northern and western US. By November 30 all but the southern most parts of the US are past peak point. “The predictive fall leaf map helps potential travelers determine the precise future date when the leaves will peak in each area of the United States，” said Wes Melton. He is one of the data scientists who created the tool. “We believe this will enable travelers to take more meaningful fall vacations, capture beautiful fall photos and enjoy the natural beauty of autumn.” The researchers refine the tool every year. This is the sixth version of the map with more and better functions. It builds on sources such as historical and forecasted temperatures. It looks at leaf peak trends and peak observation trends. These help produce the final product. Chlorophyll is the chemical responsible for turning leaves green. Plants stop producing it when fall approaches and the days get shorter. This process exposes pigments (色素), which creates the beautiful colors associated with fall foliage. Early October will likely mark the start of this year's leaf-watching season thanks to the warm weather. Tourists seeking red and golden leaves should pack their bags soon and prepare to enjoy the view. 语篇解读：本文是一篇说明文。文章主要介绍了一种交互式地图，这种地图可以预测美国各地秋季树叶变色的时间，帮助喜欢观赏秋季树叶的人们最大限度地享受这个多彩的季节。 1．What do we know about the interactive map?
