Dear Editor,

school …
Dear Editor,
I’m a student at a Shandong middle school. My hometown used to be a beautiful place. Thick forest and green grass could be seen everywhere. However, because of climate changes, it rains little now.
A possible version
In order to build houses and grow more crops, people there cut down more and more trees. As time went on, the forests were seriously destroyed. As a result, sandstorms struck us now and then, from which people suffered a lot.
To prevent the process of desertification, I hope that all the people take good care of the forest and plant more trees instead of cutting them down. Then our living conditions will soon be improved.
