怎样建立节约型社会(How to build an economized society)
To build an economized society, we must keep the following points in our mind. Firstly, make sure that the lights and the electric fans are turned off when there is no one in the room. Set the room temperature at above 26C. Remember to turn off the computer when you are not using it. Secondly, try to form the habit of turning off the tap after it is used. Use basins when washing faces or vegetables. Thus the water can be used again to clean toilets or water flowers. Thirdly, it will be good enough for us to use a basket in stead of a plastic bag when go to the market. Because a basket can be used again many more times.
