D（2025·浙江杭州·高三检测）
In a groundbreaking achievement, a rhino has successfully undergone embryo (胚胎) transfer, marking the first successful use of a method that holds promise for saving the nearly extinct northern white rhino subspecies.
The experiment, conducted with the less endangered southern white rhino subspecies, involved creating an embryo in a lab using eggs and sperm (精子) collected from other rhinos. This embryo was then transferred into a southern white rhino alternative mother in Kenya. Despite the unfortunate death of the alternative mother due to an infection in November 2023, researchers praised the successful embryo transfer and pregnancy (怀孕) as a proof of concept. They are now ready to proceed to the next stage of the project: transferring northern white rhino embryos.
Professor Thomas Hildebrandt expressed optimism about the findings, highlighting the significance of the successful embryo transfer in demonstrating that frozen and defrosted embryos produced in a lab can survive. This development offers hope for the revival of the northern white rhino population.
However, challenges facing rhino conservation remain significant. While the southern white rhino subspecies and the black rhino species have shown signs of recovery from population declines due to illegal hunting for their horns (牛角), the northern white rhino subspecies is on the edge of extinction. With only two known members left in the world, Najin and her daughter Fatu, both unable to reproduce naturally, and the recent death of the last male white rhino, Sudan, in 2018, urgent action is needed to prevent the extinction of this subspecies. Dr. Jo Shaw, CEO of Save the Rhino International, emphasized the importance of addressing the primary threats facing rhinos worldwide: illegal hunting for their horns and habitat loss due to development. She stressed the need to provide rhinos with the space and security they need to succeed in their natural environment.
While the successful embryo transfer represents a significant advancement in rhino conservation efforts, organized action is required to address the main challenges facing rhino populations worldwide.

答案： 12.D 推理判断题。根据首段“In a groundbreaking a-chievement，a rhino has successfully undergone em-bryo（胚胎）transfer，marking the first successful use of a method that holds promise for saving the nearly extinct northern white rhino subspecies.(在一项突破性的成就中，一头犀牛成功进行了胚胎移植，这标志着首次成功使用一种方法，有望拯救几乎灭绝的北方白犀牛亚种。)”可知，这是一种有望拯救该亚种的新方法的首次成功应用，由此可知，实验的目的是通过成功进行的胚胎移植拯救濒临灭绝的北部白犀牛亚种。故选D项。
13.A 词义猜测题。根据第三段中的“Professor Thom-as Hildebrandt expressed optimism about the findings(托马斯·希尔德布兰特教授对研究结果表示乐观。)”可知，托马斯·希尔德布兰特教授对新的发现持乐观态度，结合第一段中的“In a groundbreaking achievement，a rhino has successfully undergone em-bryo（胚胎）transfer，marking the first successful use of a method that holds promise for saving the nearly extinct northern white rhino subspecies.(在一项突破性的成就中，一头犀牛成功进行了胚胎移植，这标志着首次成功使用一种方法，有望拯救几乎灭绝的北方白犀牛亚种。)”可知，新的研究发现有望拯救几乎灭绝的北方白犀牛亚种。结合划线单词前的“This development offers hope for(这一发展为……带来了希望)”可推断，这一发展给拯救几乎灭绝的北方白犀牛亚种带来希望，由此可知，划线单词的意思与“复兴”意义相近。故选A项。
14.A 细节理解题。根据第四段中的“While the south-ern white rhino subspecies and the black rhino species have shown signs of recovery from population de-clines due to illegal hunting for their horns（牛角），thenorthern white rhino subspecies is on the edge of extinction.(由于非法捕猎犀牛角，南方白犀牛亚种和黑犀牛亚种的数量已经出现了恢复的迹象，而北方白犀牛亚种正处于灭绝的边缘。)”可知，北方白犀牛亚种正处于灭绝的边缘，所以，当前北方白犀牛亚种面临着灭绝的境地。故选A项。
15.C 标题归纳题。根据首段“In a groundbreaking a-chievement，a rhino has successfully undergone em-bryo（胚胎）transfer，marking the first successful use of a method that holds promise for saving the nearly extinct northern white rhino subspecies.(在一项突破性的成就中，一头犀牛成功进行了胚胎移植，这标志着首次成功使用一种方法，有望拯救几乎灭绝的北方白犀牛亚种。)”以及下文中简要介绍的实验分析和北方白犀牛亚种所面临的境地可知，本文主要介绍的是一项具有突破性意义的成就——首次成功地将犀牛的胚胎移植到犀牛体内，所以题目“成功的胚胎移植：犀牛保护的一个突破”与本文内容吻合且概括了本文的主题，适合作为最佳标题。故选C项。
