题型:改错题

In the past my hometown was used to be a beautiful place. Thick trees and green grass could be seen in everywhere. In order to build house and grow more crops, people cut down more and more trees. With time went on, the whole forest was almost destroyed. Gradually the green hills have changed into wasteland. As a result, sandstorms struck us now and then, of which we suffer a lot. However, I do hope all the people should realize the terribly result of not caring about our environment. What's more, they should take good care of the forests and plant trees instead cutting them down to improve our living conditions.
