Math diary has 200 words in the second day of junior high school.
Today, the teacher gave us a lesson on "saving energy". In class, the students talked about many ways to save energy in combination with real life. Lin Jing said, "We should try not to turn on the light during the day to avoid wasting electricity. The water used to wash your face and vegetables can be used to wash floors and clothes, and the water used to wash rice can be used to flush toilets. "

I also put forward my own views. There are three people in my family,1water consumption in October18,5 tons,1/kloc-0,5 tons. If you calculate the water saved by 1 1 month, you can save 36 tons a year, and the average monthly water consumption per person is 1 ton. Nan 'an 1.4 million people, with 65,438 people nationwide. It can save water 140 tons in one month. China has a population of over1300 million, which can save water1300 million tons a month. What a huge astronomical figure! It seems that saving water is everyone's responsibility.
