The International Union for Conservation of Nature (IUCN) added the Chinese paddlefish(白鲟) to its list of extinct species in July 2022. People will never see a living Chinese paddlefish again as it has been declared extinct. For many people in China, this might be the first time they had heard the name of the fish that was once a denizen(栖息者) of the Yangtze River Basin.
The fish is thought to have been around since about 200 million years ago. It was among the world's biggest freshwater species and could grow up to 7.5 meters in length. The last time the fish was spotted was in 2003 in the upper reaches of the Yangtze River in Yibin, Sichuan Province. It was an injured female sturgeon(鲟鱼). After local people treated its wounds, it was released into the river.
According to the IUCN, the global sturgeon reassessment found that 100 per cent of the remaining 26 sturgeon species in the world are now at risk of extinction, up from 85 per cent in 2009. Their decline over the past three generations is steeper than previously thought.
"The extinction of the Chinese paddlefish should be a warning to everyone," said Zhou Fei, China's chief program officer at the World Wide Fund for Nature. "It has provided an opportunity for conservation experts to raise public awareness about the urgency of protecting freshwater species in the Yangtze River Basin and educate the public on the need for more efforts to save other species living in the region from extinction," he added.
To prevent further loss of freshwater species in China, people must act urgently. There is no time to waste. Also, long-term threats to their life and habitats must be eliminated by taking systematic protection measures. The protection of biodiversity will delay the extinction of some species. It's not something that can be achieved by certain departments. Instead, it requires joint efforts from all sectors of society.

答案： 1. A 考查推理判断。根据第一段内容可知,国际自然保护联盟(IUCN)在2022年将中国白鲟列入灭绝物种名单,因为这个曾经生活在长江流域的物种已经不复存在。由此可推知,这一举动表明了采取保护行动的迫切需要。故选 A。 2. C 考查推理判断。根据第二段的内容可知,本段从白鲟生存的年代、体形以及最后一次出现的时间等方面提供了一些有关白鲟的资料,故选 C。 3. C 考查细节理解。根据倒数第二段中的"The extinction of the Chinese paddlefish should be a warning to everyone"以及"It has provided an opportunity... living in the region from extinction"可知,白鲟的灭绝给人们敲响了警钟,反映了保护长江流域淡水物种的需要。故选 C。 4. B 考查词义猜测。根据上文中的"To prevent further loss of... to waste"可知,为了防止更多淡水物种的消失,人们必须紧急行动起来,因此对淡水物种生命和栖息地的长期威胁应该被消除。由此推知,画线词与 removed 为同义词,意为"消除"。故选 B。
