Protecting China's "Living Fossils (活化石)"
On a sunny morning, hundreds of volunteers gathered by the Yangtze River in Yichang. A special ship from China's Fishery Department was ready to release (释放) 230,000 Chinese sturgeons (中华鲟) into the water. These fish usually lay eggs in this area. The China Three Gorges Corporation organized this activity. Since 1982, their research center has worked to protect the river's biodiversity (生物多样性) around the Three Gorges Dam, the world's largest hydro power plant (水电站). Releasing sturgeons is part of their plan to save the Yangtze's ecosystem.
Why Sturgeons Matter?
Chinese sturgeons have hard, armor - like skin. Scientists call them "living fossils" because they've looked almost the same for 140 million years. But now, they're in danger. Overfishing, pollution, and dams have made their numbers drop sharply. In the wild, fewer than 100 adult sturgeons may remain.
How Scientists Help?
Releasing sturgeons isn't easy. In the 1980s, most released fish died quickly. Engineer Jiang Wei explained, "When my team started in 1985, there were no books about sturgeon breeding. We had to learn everything ourselves." Scientists studied two key factors for 10 years:
1. Best water temperature: 18 - 20°C
2. Safe food types for young fish
By 1995, their methods improved. Released sturgeons grew to 30cm long, and more survived in the wild. Over the past 30 years, 21 million sturgeons and other endangered fish have been released into the Yangtze River.
()1. Only 230,000 Chinese sturgeons have been released into the Yangtze River so far.
()2. The China Three Gorges Corporation organized the activity of releasing sturgeons to protect the Yangtze's ecosystem.
()3. Chinese sturgeons have changed a lot in appearance over the past 140 million years.
()4. In the 1980s, most of the released sturgeons could survive in the wild.
()5. Scientists studied the best water temperature and safe food types for young sturgeons for 10 years.

#### A
根据短文内容，判断下列句子的正（T）误（F）。
##### 保护中国的“活化石”
在一个阳光明媚的早晨，数百名志愿者聚集在宜昌的长江边。中国渔业部门的一艘特殊船只准备将23万尾中华鲟放入水中。这些鱼通常在这个区域产卵。中国三峡集团组织了这次活动。自1982年以来，他们的研究中心一直致力于保护三峡大坝（世界上最大的水电站）周边河流的生物多样性。放流中华鲟是他们拯救长江生态系统计划的一部分。
##### 中华鲟为何重要？
中华鲟有着坚硬如盔甲般的皮肤。科学家们称它们为“活化石”，因为在1.4亿年的时间里它们的外观几乎没有变化。但现在，它们正面临危险。过度捕捞、污染和水坝建设使它们的数量急剧下降。在野外，可能只剩下不到100条成年中华鲟。
##### 科学家如何助力？
放流中华鲟并非易事。在20世纪80年代，大多数被放流的鱼很快就死亡了。工程师姜伟解释说：“当我的团队在1985年开始这项工作时，没有关于中华鲟繁殖的书籍。我们必须自己摸索一切。”科学家们对两个关键因素进行了10年的研究：
1. 最佳水温：18 - 20℃
2. 幼鱼的安全食物种类
到1995年，他们的方法得到了改进。被放流的中华鲟长到了30厘米长，并且更多的个体在野外存活了下来。在过去的30年里，已有2100万尾中华鲟和其他濒危鱼类被放流到长江中。
（ ）1. 到目前为止，只有23万尾中华鲟被放流到长江中。
（ ）2. 中国三峡集团组织放流中华鲟的活动是为了保护长江的生态系统。
（ ）3. 在过去的1.4亿年里，中华鲟的外观发生了很大变化。
（ ）4. 在20世纪80年代，大多数被放流的中华鲟能在野外存活。
（ ）5. 科学家们对中华鲟幼鱼的最佳水温和安全食物种类研究了10年。
