The uses of trees Trees are very important in our daily lives. They can help us in many ways. First, trees are home to animals and birds and provide them with enough food, and trees can help keep the balance of nature. Second, trees are able to stop earth moving away with water and make less land become a desert. Third, for human beings, trees have a lot of uses. Trees can provide us with many things, such as fruit, medicine and wood. Fourth, trees can produce oxygen for people to breathe, keep air cool and clean. We can make our environment better by protecting trees. Trees are so useful that we cant imagine a world without trees. So it is vital for us to protect trees. Good morning. My name is LiYi. I am a junior high school student. Our school asks our students to save water. Today, Id like to tell you how I take action to save water. In daily life, I do a lot to save water. For example, when I wash my face, I often use a washing basin. After washing the face, I reuse the water to wash the toilet. When I brush my teeth, I always turn off the tap. And I always take short showers. What I do now is not enough. I will do more to save water and work harder to protect the environment in the future. Thats all. Thank you.Monday April 2nd SunnyToday we had a class meeting. It was held in the third class in the afternoon. Mrs. Sun was present. At the meeting, our class was divided into four groups to talk about how to save water. I spoke at the meeting and gave three pieces of advice. First, turn off the tap after using it. Second, wash clothes by hands, not by the washing machine. Third, take a shower instead of bathing. All my classmates thought they were useful. I think the meeting is very meaningful.Water is very important to humans. We cant live without water. The amount of fresh water is becoming less and less now, but some people still dont care about this. They waste a lot of water. They pour dirty water into rivers and pollute them. They throw rubbish into them too. So we must protect water and find ways to reuse it. If we dont, the last drop of water will be a tear drop.Using electricity safelyElectricity is very important in our daily lives. Electrical appliances make our lives more convenient.
