I lived in a big city. There are lots of tall buildings. We can see the green mountains. I lived in a beautiful mountain with my grandparents. The air was very clean, and the little falls were cool. And when it is Sprint, I will go with my grandparents and went to near river to catch some tadpoles. I always catch lots of tadpoles and put them into a big pot, and look them became the frogs. But now, there's no river anymore. And the air is not much clean than before. We don't straight drink the good milk from the cows. And there are not much time to stay with grandparents. We should protect the environment, and take more time stay with parents and grandparents.
