In fact, water is an important part of all plants and animals. For example, about 95% of the weight of a cucumber is water. For animals, that figure is usually around 60%. When we are born, about 70%-80% of our body weight is water. This number goes down as we grow up. For an adult man, water makes up about 60% of the body weight. The amount of water is a bit lower for women: around 55%. This is because women usually have more body fat than men. A lot of water leaves our bodies every day, so we need to replace it. Adults need to drink about 2-3 litres per day to stay healthy. Every time we go to the bathroom, we lose water. Every day, there is around 1.5 litres of water in our urine. If your urine is very yellow, you need to drink more water. The body also loses water to help it cool down. This is called sweat. We lose about 500 ml of water as sweat per day. It is normal to sweat a lot when we do sport or go out in hot weather. However, if we lose more than 5% of our body weight in water, we will get tired. It is dangerous to lose more than 10%. If that happens, we will feel ill. Remember to bring a water bottle every time you play sport! 1. How much of a cucumber's weight is water? A. About 60%. B. About 55%. C. About 95%. D. About 70%. 2. How much water is in an adult man's body? A. Around 55%. B. About 60%. C. 70%-80%. D. About 95%. 3. Why do women have less body water than men? A. Because women are shorter. B.

D. We will sweat more. B Water is very important to the human body. Our bodies are made up of a lot of water. For adult men, about 60% of their body weight is water. For adult women, it is around 55%. Newborn babies have the most water in their bodies, about 70%-80%. We lose water every day through urine and sweat. We lose about 1.5 litres of water in urine and 0.5 litres in sweat every day. So we need to drink 2-3 litres of water daily to stay healthy. If we don't drink enough water, we will get tired and even feel ill. Drinking enough water is good for our health. It helps our bodies work well, keeps our skin healthy, and helps us stay cool in hot weather. Remember to drink water every day! 6. Who has the most water in their bodies? A. Adult men. B.
