| Great changes have been taken place in my village. Ten years ago, the small and low houses, which|
lie on the north of a lake, produced much waste. As the result, the lake was serious polluted. To the
west was a sandy field, that was the source of dust. Better still, a brickyard on the southwest side of
the lake used up a great deal good soil. Now the poor house have been replaced by green trees and the
brickyard by tall buildings. The sandy field that the villagers used to ploughing has been covered with fruit
trees. On the lake the villagers often spend his spare time boating and fishing.
