It affects not only the health of humans but also the survival of plants and animals. Understanding the causes and effects of water pollution is the first step toward solving this problem. There are many causes of water pollution. One of the main causes is industrial waste. Factories often release chemicals and heavy metals into rivers and lakes without proper treatment. These substances can be very harmful to living organisms. Another major cause is agricultural runoff. Farmers use fertilizers and pesticides to increase crop production. When it rains, these chemicals are washed into nearby water bodies, causing pollution. Household waste is also a significant contributor. Many people throw garbage and plastic into rivers, which not only pollutes the water but also harms aquatic life. The effects of water pollution are severe and far-reaching. Polluted water can cause many diseases in humans, such as cholera and typhoid. It also kills fish and other aquatic animals, disrupting the food chain. Moreover, water pollution makes water unfit for drinking, bathing, and farming. This can lead to water shortages and food scarcity in many regions. In conclusion, water pollution is a global problem that requires immediate attention. Everyone can play a part in reducing water pollution by adopting greener habits in their daily lives. ( )1.

I have been a volunteer for an environmental protection organization for three years. During this time, I have participated in many activities aimed at protecting the environment. Today, I want to share one of my most memorable experiences with you. Last summer, our team organized a river clean-up activity in my hometown. The river used to be clean and clear when I was a child. However, in recent years, it has become heavily polluted. People had been throwing garbage and pouring wastewater into it for a long time. The water turned dark and smelly, and the fish disappeared. The local community was worried about the situation and wanted to do something to help. On the day of the activity, more than fifty volunteers came together. We spent the whole morning cleaning up the riverbanks. We collected plastic bottles, bags, and all kinds of trash. Some volunteers even used nets to remove floating garbage from the water. By the end of the day, we had collected dozens of bags of waste. It was hard work, but we all felt very proud. Since that day, the community has taken better care of the river. People have stopped throwing garbage into it. Now, the water is much cleaner and you can see fish swimming in it again. This experience taught me that small actions can make a big difference. I believe that if everyone does their part, we can protect our environment and create a better world for future generations. ( )6. How long has Chen Wei been a volunteer? A. One year. B. Two years. C. Three years. D. Four years. ( )7. What was the condition of the river before the clean-up? A. It was clean and clear. B. It was heavily polluted. C. It was full of fish. D. It was used for swimming. ( )8. What did the volunteers do during the activity? A. They planted trees along the river. B. They cleaned up the riverbanks and removed garbage. C. They built a new bridge. D. They painted the riverbanks. ( )9. What has happened to the river since the clean-up? A. It has become more polluted. B. People have stopped throwing garbage into it. C. The fish have all died. D. The water has turned dark again. ( )10. What lesson did Chen Wei learn from this experience? A. Cleaning rivers is a waste of time. B. Small actions can make a big difference. C. Only volunteers can protect the environment. D. The river will never be clean again. 八、完形填空（阅读下面的短文，从每题所给的A、B、C、D四个选项中选出最佳选项） Water pollution is one of the most (1) ______ environmental problems in the world.

I believe that everyone can make a difference in protecting the environment. First of all, I have ridden my bike to school instead of taking the car for two years. This not only helps reduce air pollution but also keeps me healthy. Second, I have been used to thinking twice before throwing things away. I recycle paper boxes, plastic bottles, and glass jars. I also avoid using plastic bags when shopping. Third, I have joined a tree-planting club in my school. Every year on Tree-planting Day, we plant trees in our community. I am proud of what I have done, but I know there is still a lot more to do. I hope more people will join me in protecting our planet. Together, we can make the world a greener and better place for future generations. 学科网（北京）股份有限公司 $
