They were born in 1989 and 2000 and now live in the OI Pejeta Reserve in Kenya. The northern white rhino is a species of the white rhinos that were once found in several countries across Central and East Africa.They are grazers primarily feeding on grasses. Sadly, due to illegal hunting and habitat loss, the northern white rhino is now on the edge of extinction. Professionals have been making great efforts to protect them. The reserve provides 24-hour armed guards to ensure their safety. Scientists are also working hard on reproductive technologies. They have successfully collected female reproductive cells from Najin and Fatu and created embryos (胚胎) through man-made process with frozen reproductive cells from male northern white rhinos. However, challenges remain. The two female rhinos are unable to carry the embryos naturally due to age and health problems, and the process of putting embryos into southern white rhinos is difficult and time-consuming. Despite these difficulties, professionals are still focused on saving this precious species, hoping to prevent their complete disappearance. The leading scientist Thomas Hildebrandt said, “We achieved together something which was not believed to be possible. That is really a milestone to allow us to produce northern white rhino calves in the next two years.” Still, other scientists like Steven Seet argued, “We have to consider some questions before starting the project. Should we devote so much to a species with only two females left? Should we humans continue to make decisions for this endangered species？” 语篇解读：本文是一篇说明文。文章主要讲述了人们为保护地球上最后两只北方白犀牛所作出的努力。 1．What does the underlined word “grazers” in paragraph 2 refer to?

A．Doubtful. B．Positive. C．Supportive. D．Unconcerned. 解析：观点态度题。根据最后一段中连续的疑问句可知，Steven Seet对于保护行为持怀疑态度，故选A。 √ 4．What is the main idea of the text? A．The variety of global wildlife species. B．The introduction of OI Pejeta Reserve. C．The efforts of saving northern white rhinos. D．The overview of wildlife preservation history. 解析：主旨大意题。根据全文内容，并结合第三段中的“Professionals have been making great efforts to protect them.”可知，文章主要讲述了人们为保护地球上最后两只北方白犀牛所作出的努力，故选C。 √ (二)完形填空 The suburb I live in backs onto a large nature reserve (自然保护区).
