Question

 Have you ever seen the pictures of those suffering people who struggle every day for just a few drops of water? Water is not a neverending resource,but a precious resource that is more valuable than anything else on the planet. Water is the most important thing for life,even greater than food. But drinking water is less and less. It is important that people understand this and saving water is the proper thing to do.

According to a senior official,China is facing a more serious water crisis than any other country in the world. Measures must be taken to save water in its cities. The crisis is caused by widespread drought,pollution,rapid economic growth and waste.

It is important to use water wisely. With so many ways to save water,here are the highlights to help you save water around your home. By following these simple sug?gestions,you will save money on your water bill.

Vegetables and fruit should be washed in a bowl rather than under a running tap and the leftover water can be used for watering plants. Never put water down the drain (排水管) when there may be another use for it such as watering a plant or cleaning.

Avoid washing the toilet unnecessarily. Do not use your toilet as a wastebasket. Take shorter showers. Do not let water running while shaving,brushing your teeth or washing your hair or face. Recently,Singaporeans were urged to shower a minute less as part of a national water conservation effort.

Operate automatic dishwashers and clothes washers only when they are fully loaded or properly set the water level for the size of load you are using.

By thinking carefully about your water use in the home and changing some waterwasting habits,it is easy to save water.
