B．Controversial.C．Ambitious. D．Successful.2．What does Paul Beer say about the new-born rhino?A．She loves staying with her mother.B．She dislikes outdoor activities.C．She is in good condition.D．She is sensitive to heat.3．What similar experience do Solio and Kisima have?A．They had their first born in January.B．They enjoyed exploring new places.C．They lived with their grandmothers.D．They were brought to the reserve young.4．What can be inferred about Port Lympne Reserve?A．The rhino section will be open to the public.B．It aims to control the number of the animals.C．It will continue to work with the World Wildlife Fund.D．Some of its rhinos may be sent to the protected wild areas.【语篇解读】本文是一篇说明文。文章主要介绍了保护和繁育濒临灭绝的黑犀牛。1．D　推理判断题。根据第一段中的“as black rhinos are known for being difficult to breed in captivity(圈养)”可知，黑犀牛以难以圈养繁殖而闻名，而繁育计划成功迎来了一只稀有的黑犀牛幼崽，由此可推断该计划是“成功的(successful)”。故选D项。2．C　细节理解题。根据第二段中的“She’s healthy，strong and already eager to play and explore.”可知，犀牛幼崽健康、强壮，并且渴望玩耍和探索。由此可知，犀牛幼崽身体状态良好。故选C项。3．A　细节理解题。根据第一段中的“When the tiny creature arrived on January 31”和第三段中的“The first rhino to be born at Port Lympne arrived on January 5 to first-time mother Kisima”可知，Solio和Kisima都是在一月份生下它们的第一只犀牛幼崽的。故选A项。4．D　推理判断题。根据第三段中的“...but it is too early to tell if the calves will make good candidates to be returned to protected areas of the wild.”可知，要判断这些小犀牛是否会成为返回野生保护区的优秀候选者还为时过早。由此可推断，Port Lympne保护区中的一些犀牛可能会被送到野生保护区。故选D项。Ⅲ.书面表达(2022－2023学年河南省新高考联盟高一教学质量检测)假定你是校英文报的记者李华，请写一篇新闻稿，报道你校上周末组织的以“保护湖泊”为主题的志愿活动。内容包括：1．活动的时间、地点、过程；2．活动的意义。注意：1.词数 80 左右；2．可以适当增加细节，以使行文连贯。Lake Protection__________________________________________________________________________One possible version：Lake ProtectionLast weekend witnessed a meaningful volunteer activity to promote the importance of lake protection.The students willing to play a role in protecting the lake gathered in front of the school gate at 8 am last Sunday.Then they set out to do a variety of things to help protect the lake.Some picked up plastic waste by the lake near our school，while others handed out leaflets on the streets to call for more people to make an effort.The volunteer activity was highly spoken of because it not only heightened our awareness of lake protection but also motivated more people to take part in making the earth a better place.
