In today's class, we learned litres and milliliters. I know what is expressed in liters and what is expressed in milliliters in life. What impressed me most in this class was drinking water, which made me know that adults drink 1.5 liters of water every day and children drink 1 liter of water every day, which is healthy drinking water.

After returning home, I did an exercise. I saw an open faucet dripping about 8 ml of water a minute, and I thought, it's no big deal, just 8 ml of water! But at this moment, my mother told me: "Waste 8 ml in one minute, 480 ml in one hour, 1 1520 ml of water in one day, and 4,204,800 ml of water in one year." Wow! With so much water, China has a population of 654.38+300 million. If everyone does not turn off the tap after use, it will waste 546.624 billion milliliters of water, that is, 546.624 billion liters of water. I was scared to death when I saw this number. How much water is this? If all this water is donated to the arid areas, can't it alleviate the drought?

Finally, I want to appeal to people: save water, save the water resources of the earth, and cherish every drop of water! Don't let the last drop of water on the earth turn into human tears! ! !
