One of the factors likely to have led to the death of sea stars is rising ocean temperatures caused by climate change，according to some scientists.The ocean absorbs most of the excess atmospheric heat caused by greenhouse gas emissions，which has the effect of increasing the temperature of the water.Many sea creatures can only tolerate very small changes to their environment. Sunflower sea stars feed on sea urchins.Sea urchins feed on seagrass.Without the presence of sunflower sea stars，their key predator in the food chain，sea urchin populations have boomed.That has led to the death of many seagrasses—which in turn contributes to the climate crisis，as seagrass is a valuable tool to store carbon dioxide. Scientists at the University of Washington have been working on that.They have been raising a new generation of sunflower sea stars that can be used to repopulate coastal waters.Jason Hodin，a research scientist at the University of Washington's Friday Harbor Labs，said that they're hoping the program can help recover the sunflower sea star and，ultimately，recover the health of ecosystems like seagrass that is under threat right now. To test the sea stars' ability to tolerate warming seas，scientists have these tiny creatures subjected to fluctuations (波动) in water temperatures in the lab.Some of the young adult sea stars are being raised in water that is slightly warmer than normal，and are showing signs of being able to adjust to the added warmth.“These are not typical ocean temperatures around here，but the success indicates that they at least have the ability to endure the warmer water，” said Hodin. 1．Which could be a possible reason for the death of sunflower sea stars? A．Habitat loss. B．Climate change. C．Food shortage. D．Ocean pollution. 2．What does Paragraph 3 mainly talk about? A．The living habits of sunflower sea stars. B．The importance of seagrass to the environment. C．The key role of sunflower sea stars in the food chain. D.The consequences of the increasing sea urchin populations. 3．How do scientists help increase the population of sunflower sea stars? A．By developing devices to cool sea water. B．By improving the environment of coastal waters. C.By growing plentiful seagrass to absorb carbon dioxide. D．By experimenting on raising a new generation of the creature. 4．What does Jason Hodin think of the program? A．It is meaningful. B．It is complicated. C．It is bizarre. D．It is disappointing. 【语篇解读】本文是一篇说明文。从墨西哥的下加利福尼亚半岛到阿拉斯加的太平洋海岸线上的向日葵海星数量锐减，其原因之一可能是气候变化导致的水温升高。华盛顿大学的科学家们正培育新一代的向日葵海星来增加向日葵海星的数量。 1．B　[解析]细节理解题。根据第二段第一句“One of the factors ...is rising ocean temperatures caused by climate change，according to some scientists.”可知， 气候变化可能是海星死亡的原因之一。故选B。 2．C　[解析]主旨大意题。根据第三段可知，因为食物链中缺失向日葵海星，导致海胆没了天敌而数量激增，海草数量因此减少，这反过来加剧了温室效应，因为海草是储存二氧化碳的宝贵工具。由此可推知，本段主要讲述了向日葵海星在食物链中的关键作用。故选C。 3．D　[解析]细节理解题。根据第四段中的“They have been raising a new generation of sunflower sea stars ...recover the health of ecosystems like seagrass that is under threat right now.”可知，科学家通过实验培育新一代向日葵海星来帮助增加向日葵海星的数量。故选D。 4．A　[解析]推理判断题。根据倒数第二段最后一句“Jason Hodin，a research scientist at the University of Washington's Friday Harbor Labs ...recover the health of ecosystems like seagrass that is under threat right now.”和最后一段可知，实验发现年轻的成年海星能够在比正常温度稍高的海水中长大，并显示出能够适应升高的温度的迹象。这一成功案例证明这个项目是有意义的，可以为最终恢复目前受到威胁的海草等生态系统的健康指明方向。故选A。 Ⅴ.语法填空 (2024·杭州高二检测)The Qinghai Lake National Nature Reserve in northwest China's Qinghai Province has updated 1.__________(it) list of protected wildlife，adding 10 species 2.__________ the previous total of 72，according to a report by the Xinhua News Agency.The updated list，which was revised by experts，3.__________(include) 82 species of protected wildlife.The number of national first­level protected animals has increased from 19 to 22.Meanwhile，the number of second­level nationally protected animals has increased from 53 to 60.4.__________(addition)，the number of wild plants under national protection has reached 12 species.According to the report，the 5.__________(revise) of the wildlife list focused on optimizing(优化) 6.__________ adjusting the bird list.Species with uncertain records were removed from the original list and new species that have been monitored in recent years were added，increasing the total number of bird species from 232 to 281.
