     In the past, my hometown used to be beautiful place.               
Thick trees and green grass can be seen everywhere. In             
order to build houses and grow up more crops, people cut           
down more and more trees. With time went on, the whole forest      
was almost destroyed. Gradually the green hills have been become   
wasteland . As a result, sandstorms strike us now or then, from   
that we suffer a lot. So, I do hope all the people should          
realize the terribly result of not caring about our environment.   
what’s more, you should take good care of the forests and plant   
trees instead of cutting them down to improve our live conditions.  		1______
