英文小作文：

Contour lines are a common feature of maps and charts, and they help us understand the shape of the land and other terrain features. They are usually shown as lines that connect points with similar elevations, and they can be used to identify areas with different elevations and slopes. On a map, contour lines can help us understand how far we have to go up or down, and they can also indicate areas that are particularly steep or difficult to cross.

For example, if we are hiking in a mountainous area and we see a map with contour lines, we can use them to plan our route and avoid areas that are too steep or difficult to navigate. Additionally, contour lines can be used in other contexts, such as studying the terrain for military or natural resource purposes, or in environmental monitoring to identify areas that may be at risk of erosion or flooding. Therefore, contour lines are an essential tool for anyone who needs to understand the terrain and its features.
