①About 70% of our body is water. We can live with no water for only about three days. So you can see water is really important for us!
②In fact, water helps our bodies in many ways. First, water keeps us healthy. Like trees and flowers need water to grow, our bodies need water to work well. Next, water is like a cleaner for our bodies. It can dust off our bodies and keep us healthy. Did you know that water also helps us stay cool when we feel hot? Our bodies get hot and sweaty(出汗的) when we play outside or run around. But drinking water cools us down and makes us feel good. It’s like a great drink on a hot day. Water is also good for our skin. It keeps our skin soft. So, if we want nice skin, we can drink enough water.
③But how much water should we drink? For most of us eight glasses of water every day may be OK. But those who live or work in warmer places need to drink more water. That is because they lose more water than us.
④And we have to know some rules about drinking water. After getting up or one hour before meals, it is helpful to drink a glass of water. Drink often before we feel thirsty. In fact, when we feel thirsty, the body is already short of water.
⑤You see, water is so good for us. So, remember to drink enough water every day to stay healthy!
