Let’s follow a water drop on its long journey. My name is Drippy. I live in a beautiful mountain lake. The water here is clean and fresh. One sunny day, the sun shone down on me. I began to feel warm and light. Slowly, I rose into the air. I was evaporating (蒸发)! Together with many other water drops, I formed a cloud. The wind pushed us across the sky. We travelled for hundreds of kilometres. Finally, the air became cold. I turned back into a water drop and fell to the ground. This is called precipitation (降水). I landed on a hill. Slowly, I flowed into a small river. The river carried me to a reservoir (水库). People built the reservoir to collect fresh water. From the reservoir, I travelled through long pipes. The pipes took me to a water treatment plant (水处理厂). Workers cleaned me and made me safe to drink. Finally, I travelled through underground pipes to a house. When someone turned on the kitchen tap, I came out. From a mountain lake to a kitchen tap — what a long journey! Now you know. Every time you drink a glass of water, remember the long journey of that water drop. And don’t forget to turn off the tap. Every drop is precious. 36. Drippy started his journey from a river. 37. Evaporation happens when water drops feel warm and rise into the air. 38. After travelling in the cloud, Drippy fell to the ground as snow. 39. People built reservoirs to collect fresh water. 40. The water drop went to a water treatment plant to be cleaned. B 阅读下面短文，从各题所给的 A、B、C、D 四个选项中，选出最佳选项。（共 5 小题；每小题 1.5 分，满分 7.5 分） Water Crisis: A Growing Problem Water is essential for all life on Earth. However, more than 2 billion people around the world do not have access to clean drinking water. This is called the water crisis (危机). Why is there a water crisis? First, climate change is making many areas drier. Rain falls less often, and rivers are drying up. Second, the world’s population is growing. More people mean more water is needed for drinking, farming, and factories. Third, pollution is a big problem. Factories and farms pour chemicals into rivers and lakes, making the water unsafe to use. What happens when there isn’t enough water? When people don’t have enough clean water, they may get sick from drinking dirty water. Every year, millions of people, especially children, die from water-related diseases. Women and girls often have to walk many kilometres every day to fetch water. This takes time away from school and work. How can we help? The good news is that everyone can do something to help. At home, we can take shorter showers and turn off the tap when we brush our teeth. At school, we can start a water-saving club. In our community, we can join river clean-up activities. Some organisations are also building wells (井) and water treatment systems in areas that need them. Every drop counts. Let’s work together to protect our water resources for future generations. 41. How many reasons for the water crisis are mentioned in the passage? A. One. B. Two. C. Three. D. Four. 42. According to the passage, what is one effect of climate change on water? A. Rivers are becoming wider. B. Rain falls less often in many areas. C. Water becomes easier to find. D. Lakes are getting deeper. 43. Why do women and girls have to walk a long way every day in some areas? A. To fetch water. B. To work in factories. C. To go to school. D. To visit their families. 44. What does the word “fetch” in paragraph 3 probably mean? A. To drink. B. To carry. C. To clean. D. To go and get. 45. Which of the following is NOT mentioned as a way to help save water? A. Taking shorter showers. B. Turning off the tap while brushing teeth. C. Building more factories. D. Starting a water-saving club at school. C 阅读下面短文，从各题所给的 A、B、C、D 四个选项中，选出最佳选项。（共 5 小题；每小题 1.5 分，满分 7.5 分） Saving Water in Our Daily Lives Water is one of the most valuable resources on Earth. Without it, no living thing can survive. However, many people waste water without even realising it. The good news is that small changes in our daily habits can make a big difference. In the bathroom Taking a bath uses up to 150 litres of water at a time, while a five-minute shower uses only about 60 litres. That’s a saving of 90 litres of water each time! Also, turning off the tap while brushing your teeth can save over 100 litres of water per week. One dripping tap can waste up to 5,000 litres of water in a year. If you see a dripping tap, fix it immediately or tell an adult. In the kitchen When washing vegetables, use a bowl instead of running water. You can reuse that water to water your plants. When doing the dishes, don’t let the water run continuously. Fill the sink with water instead. Run the dishwasher only when it is full. In the garden Water your plants early in the morning or late in the evening. That way, less water evaporates under the hot sun. Collect rainwater in a barrel to use for watering your garden. Choose plants that don’t need much water to grow. Beyond home Encourage your family and friends to save water too. Join community water-saving activities. Report leaking pipes in your neighbourhood. Every action, no matter how small, helps protect our precious water resources. 46. How much water can a five-minute shower use? A. About 150 litres. B. About 60 litres. C. About 90 litres. D . About 100 litres. 47. What does the underlined word “dripping” in paragraph 2 probably mean? A. Falling in small drops. B. Running very fast. C. Making loud noise. D. Turning very hot. 48. How can you save water when washing vegetables according to the passage? A. Wash them under running water. B. Throw away the water directly. C. Wash them one by one. D. Use a bowl instead of running water. 49. Why should you water plants early in the morning or late in the evening? A. Because plants grow faster at that time. B. Because less water evaporates under the hot sun. C. Because it is easier to water plants then. D. Because it saves time. 50. What is the main purpose of this passage? A. To explain why water is important. B. To show how much water we use every day. C. To give tips on saving water in daily life. D. To tell people to drink more water.
