The water cycle is a continuous process that includes evaporation, condensation, and precipitation. When the sun heats the water in oceans, lakes, and rivers, it turns into water vapour and goes up into the air. As the water vapour cools down, it turns into tiny water droplets, forming clouds. Then, the water droplets fall back to the Earth as rain, snow, or hail. The water cycle is very important for our environment. It helps to regulate the Earth's temperature and provides fresh water for plants, animals, and humans. However, human activities can have an impact on the water cycle. For example, deforestation can reduce the amount of water that is absorbed by the soil and evaporated into the air. Climate change can also cause changes in precipitation patterns, leading to more floods or droughts in some areas. 1. Please give a brief summary of the water cycle process.

Thank you. 【解析】发言稿需包含节约用水的原因及个人节水措施，围绕这些要点展开即可。 阅读下面短文，然后回答问题。 Water is not only important for our life but also plays a significant role in nature. The water cycle is a continuous process that includes evaporation, condensation, and precipitation. When the sun heats the water in oceans, lakes, and rivers, it turns into water vapour and goes up into the air. As the water vapour cools down, it turns into tiny water droplets, forming clouds. Then, the water droplets fall back to the Earth as rain, snow, or hail. The water cycle is very important for our environment. It helps to regulate the Earth's temperature and provides fresh water for plants, animals, and humans. However, human activities can have an impact on the water cycle. For example, deforestation can reduce the amount of water that is absorbed by the soil and evaporated into the air. Climate change can also cause changes in precipitation patterns, leading to more floods or droughts in some areas. 1. Please give a brief summary of the water cycle process. (No less than 40 words) ________________________________________________________________________________________________________________________________________________________________________________________ 【中文答案】水循环包括蒸发、凝结和降水等过程。太阳加热海洋、湖泊和河流中的水，使其变成水蒸气进入空气。水蒸气冷却后形成云，然后以雨、雪或冰雹的形式返回地球。 【English answer】The water cycle includes evaporation, condensation and precipitation. The sun heats water in oceans, lakes and rivers, turning it into water vapour that goes into the air. When the water vapour cools, it forms clouds, and then falls back to the Earth as rain, snow or hail. 2. According to the passage, analyze the impact of human activities on the water cycle. (No less than 40 words) ________________________________________________________________________________________________________________________________________________________________________________________ 【中文答案】人类活动如砍伐森林会减少土壤吸收和蒸发的水分。气候变化会使降水模式改变，导致一些地区洪水或干旱增多。 【English answer】Human activities like deforestation can reduce the water absorbed by the soil and evaporated into the air. Climate change can alter precipitation patterns, causing more floods or droughts in some areas. 3. As a middle school student, what can you do to protect the water cycle? Please put forward two suggestions. (No less than 40 words) ________________________________________________________________________________________________________________________________________________________________________________________ 【中文答案】中学生可以采取的措施包括节约用水、参与植树活动、宣传环保意识等。 【English answer】Middle school students can save water, take part in tree - planting activities and promote environmental awareness. 1 / 12 学科网（北京）股份有限公司 $$
