    Great changes have been taken place in my village. Ten years ago, the small and low houses of my village lie on the north of a lake. The villagers produced many waste. As a result, the lake was serious polluted. To the west of the village was a sandy field, where was the source of much dust.

    Now the poor house have been replaced by green trees. However, the sandy field that the villagers used to plough has been covered of fruit trees. On the lake, now clean and clear, the villagers often spend their spare time fish.

    In word, my village has become a green one.
