2. 范文示例
A Beautiful Natural Scenery
There are many amazing natural sceneries in the world, and my favorite one is the mountain forest near my city. It’s a beautiful place that makes people feel close to nature.
The forest is full of tall and green trees, and the air there is the freshest I have ever breathed. When you walk in the forest, you can hear birds singing in the trees and small streams running beside the path. There is a small lake in the middle of the forest. The lake water is very clear, and it’s calmer than the river in the city. You can see many fish swimming in the clear water, and the mountains around the lake look higher and more beautiful in the sunshine. In spring, there are many colorful flowers on the hill, and the whole forest is full of life. In autumn, the leaves turn yellow and red, and the scene is even more amazing.
I often go to this forest with my friends on weekends. We like to climb the small hills, take photos of the beautiful view and sit by the lake to relax. This forest not only brings me happiness but also lets me know how wonderful nature is. I hope this beautiful natural scenery will stay forever, and we will always protect it.
