We need to drink at least 1.5 liters of water every day to stay healthy. Water helps digest food, regulate body temperature, and remove waste from the body. Without water, we can only survive for a few days. But many people around the world don't have access to clean water. They have to drink dirty water, which can cause serious diseases. That's why water conservation and clean water projects are so important. We can all do our part to save water. Simple actions like turning off the tap while brushing teeth, fixing dripping taps, and reusing water can make a big difference. 31. What percentage of the human body is water? A. About 50% B. About 60% C. About 70% D. About 80% 32. How much water do we need to drink every day? A. At least 1 liter B. At least 1.5 liters C. At least 2 liters D. At least 2.5 liters 33. Why is dirty water dangerous? A. It tastes bad B. It is not enough C. It can cause diseases D. It is hard to get （B） The water cycle is a natural process that recycles water on Earth. It has four main stages: evaporation, condensation, precipitation, and collection. First, the sun heats water from oceans, lakes, and rivers. This causes evaporation—water turns into water vapor and rises into the sky. Next, the water vapor cools down and forms clouds. This is called condensation. When the clouds get heavy enough, water falls back to Earth as rain, snow, or hail. This is precipitation. Finally, the water collects in oceans, lakes, rivers, or underground, and the cycle starts again. The water cycle is important because it provides fresh water for plants, animals, and humans. Without it, there would be no rain, and fresh water would soon run out. 34. How many main stages are there in the water cycle? A. Three B. Four C. Five D. Six 35. What happens during evaporation? A. Water turns into vapor B. Clouds form C. Water falls as rain D. Water collects in rivers 36. What is condensation? A. Water heats up B. Water vapor forms clouds C. Water falls to Earth D. Water collects underground 37. Why is the water cycle important? A. It makes the sky blue B. It provides fresh water C. It causes storms D. It cools the Earth （C） Many countries are facing water shortages. One of the reasons is overpopulation—more people need more water for drinking, cooking, and daily use. Another reason is pollution. Factories and farms often pour waste into rivers and lakes, making the water unsafe to use. Climate change is also a factor. Rising temperatures cause more droughts, which reduce the amount of fresh water. To solve this problem, governments are building dams and reservoirs to store water. They are also investing in water treatment plants to clean polluted water. People are encouraged to save water in their daily lives. For example, in some cities, people get fined if they waste water. We can also help by changing our habits. Using water-saving appliances, taking shorter showers, and not throwing rubbish into water bodies are all good ways to protect water resources. 38. Which is NOT a reason for water shortages? A. Overpopulation B. Pollution C. Climate change D. Water cycle 39. What are governments doing to store water? A. Building dams and reservoirs B. Fining people who waste water C. Using water-saving appliances D. Cleaning polluted water 40. How can people help save water? A. Pouring waste into rivers B. Taking longer showers C. Using water-saving appliances D. Throwing rubbish into lakes 41. What is the purpose of water treatment plants? A. To store water B. To clean polluted water C. To produce electricity D. To collect rainwater （D） A group of students from No.1 Middle School started a "Save Water" campaign last month. They wanted to raise awareness about water conservation among their classmates and community. First, they made posters with pictures and slogans like "Water is life—save every drop" and "Don't let our tears be the last drop of water". They put the posters up in their school, neighborhood, and local shops. Then, they gave a presentation to their schoolmates.
