V．短文改错
Dear editor,
Some years ago, my hometown was used to be a beautiful place.                 66.                
Thick trees and grass can be seen all over the hills.                                     67.                
As time going by, people destroyed almost the whole                              68.                
forests grow more crops. To make matters worse, people let their                    69.                
cattles eat up the grass. So, you can only see wasteland                                   70.                
instead green forests now. As a result, when it rains, the                             71.                
soil is washed down the hills and in the rivers. Strong winds also                    72.                
blow away the valuable soil lie on the top of the fields.                                  73.                
I do hope all the people will take good care of the forests                        74.                
and plant more trees to improve our living conditions better.                       75.
