五、阅读表达。
阅读短文，简略回答问题。
Hi, my name is Wei Guo. My hometown is a small mountain village in Yunnan Province. It is surrounded by green mountains, and there is a deep blue lake in the mountains.
People in my hometown believe that the lake has magical powers because it never freezes in winter, even when other nearby lakes turn to ice. Years ago, scientists came to explore the lake and discovered its secret—hot springs at the bottom kept the water warm all year round.
The lake is also home to a rare fish species（珍稀鱼类）that cannot be found anywhere else. In the past, the local people made a living by catching fish in the lake. As a result, the number of fish became smaller and smaller. To protect these fish, the government made the lake a nature reserve. Visitors were allowed, but swimming and fishing were forbidden（禁止）. At first, some villagers were unhappy about the new rules, but they soon realized that tourism brought more benefits than fishing.
In recent years, great changes have taken place in our hometown. With the help of the government, a natural scenic area has been set up around the magical lake. It attracts thousands of visitors every year. The villagers have built small hotels and restaurants, and some even work as tour guides. The lake not only provides jobs but also helps protect the environment. It is a perfect example of how nature and humans can live in harmony（和谐）. It's true that green mountains and clear waters are more valuable than mountains of gold and silver.
46. Why do people in the village think the lake has magical powers?


47. How did people in the village make a living in the past?


48. What did the government do to protect the fish in the lake?


49. What changes have taken place in the writer's hometown in recent years?（Give one example.）


50. What's your understanding about "green mountains and clear waters are more valuable than mountains of gold and silver"? (Less than 30 words.)

46. Because the lake never freezes in winter.
47. By catching the fish in the lake.
48. The government/It made the lake a nature reserve.
49. A natural scenic area has been set up around the magical lake. / It attracts thousands of visitors every year. /The villagers have built small hotels and restaurants, and some even work as tour guides.
50. Protecting the environment is far more important than getting short-term wealth.
