Yet, many people around the world face a water crisis. They do not have enough clean, safe water to drink. This crisis is caused by several factors, including pollution, climate change, and wasting water. Factories sometimes dump waste into rivers, making the water polluted. Farms use chemicals that can get into groundwater. When people waste water at home, for example, by taking long showers or leaving taps running, it reduces the amount of water available for everyone. The water cycle is the natural way water is recycled on Earth. However, human activities are disrupting this cycle. To help solve the water crisis, we must stop polluting water, use water more wisely, and develop new technologies to clean and save water. Every drop counts! 根据短文内容，选择正确答案。 1.

However, fresh water is a limited resource, and we must all do our part to save it. There are many simple ways we can save water in our daily lives. First, we should turn off the tap while we are brushing our teeth or soaping our hands. This can save a lot of water. Second, taking shorter showers instead of long baths is another effective method. Third, we can reuse water whenever possible. For example, we can use leftover water from washing vegetables to water plants. In conclusion, saving water is not difficult. Every small action counts. Let's work together to protect our precious water resources for ourselves and for future generations. 学科网（北京）股份有限公司 $
