1、One possible version:

     With the development of our economy, the environment is being damaged greatly, and at

the same time, the natural resources will be running out some day, so building up an economized

society is a must in China.

     To build up an economized society, good use must be made of water, electricity, natural

materials etc, even the smallest amount. Therefore, we should always keep in mind to turn off the

lights and electric fans before we leave the house, to switch off the taps after using them, and to

use baskets instead of plastic bags, for they can be used many times.

      As students, we should respond to the government's call to save every pencil, every piece

of paper, and even every single drop of ink. All in all, we should make every effort to save everything useful to make contributions to an economized society.
