The teacher assigned a task to combine words with the word "water" and then write a composition. Please provide me with an easy topic to write.

Composition of water: Cherish water As we all know, water is the source of life. However, this public service advertisement can't awaken many people's hearts! At present, the annual water consumption in China is about 3 1 1 100 million cubic meters. This is a lot of money! It's really thrilling.

In our school, water consumption is very high. Many students turn on the water when washing their hands, rags and mops, and some don't even tighten the tap after they leave! So many sparkling water resources are wasted by you. In fact, you don't have to turn on the tap to wash those things. You can also pay attention to the tap after you leave. Over time, this will save a lot of water.

At home, some people keep the water on when brushing their teeth, some people play water saving, and there is a lot of water when playing games … Don't think that there is water when the tap is turned on! If you go on wasting like this, even the Pacific Ocean will be wasted. I have a special water-saving coup: Taomi water can be used to wash other vegetables and then water the flowers. Bath water can be used to wash clothes at first and then mop the floor. Face wash water can be used to wash hands. Expired tea leaves can also be used to water flowers. Look! So the waste of water resources can be greatly reduced?

In society, some people are punished for wasting a lot of water. Sichuan, Wuhan, North China and so on are seriously short of water! Why is this? These are all caused by our waste. At present, there are more than 400 cities short of water among more than 660 cities in China, among which there are more than 100 cities with severe water shortage! Honey, I don't know if I didn't see it. I was shocked when I saw it! There are so many cities in China that are short of water. What about the whole world? There must be more. The river pollution in China is particularly serious. Ladies and gentlemen, children and orangutans, take a look. China is so short of water, don't waste water in the future!

Wake up, human. Didn't you hear the cries of the sea and rivers for help? Please stop sleeping and wasting.
