WELCOME UNIT Unit 6　Earth first 单元限时小练(40分钟) Ⅰ　阅读 A Every day as the sun rises, Ma Hongyi, a 66­year­old farmer, can be seen patrolling (巡逻) Yuncheng Salt Lake with his dog in Yuncheng City, North China's Shanxi Province. Ma still remembers the day when he first saw two big pink birds wandering through the water. “I had never seen such pretty birds. They were even taller than me, with long wings，” Ma recalls. He was later told that the birds were flamingos, a rare sight in China, which were listed on the International Union for Protection of Nature's Red List of endangered species in 2013. From that day on, Ma started his second career as a volunteer to prevent human beings from interfering with the wildlife. “The birds are attracted by the good environment，” Ma says. “I will do my best to protect the lake so that birds can come here every year.” Yuncheng Salt Lake covers an area of 132 square kilometers and used to serve as a salt production base. As the country began attaching greater importance to environmental protection, an ecological (生态的) protection and development center was set up in 2012 to carry out regular ecological protection and restoration (修复) of the lake. “The greatest value of the Salt Lake lies in its ecology, which should be properly restored and protected，” says Chu Xianghao, mayor of the city. The lake area hosts 292 types of wild animals, along with 782 plant varieties, some of which are newly recorded species in the country. After patrolling the lake as a volunteer for over four years, Ma was employed by the local government to help with wildlife protection in 2019. “The lake's ecology is getting better，” Ma says, adding that he looks forward to the arrival of the flamingos every year. “Some of them are my old friends，” he says. 篇章导读：本文是一篇新闻报道。文章报道了山西运城盐湖护鸟人马红义的故事，展现生态保护对珍稀鸟类栖息地的重要价值。 1．What does the underlined phrase “interfering with” in Paragraph 2 probably mean? A．Bringing benefits to. B．Losing control of. C．Sharing space with. D．Causing problems to. 解析：词义猜测题。根据画线短语后文“The birds are attracted ... here every year.”可知，马红义为了保护这个湖，让鸟儿每年都能来这里而开始巡逻盐湖，他的目的是阻止人类活动对野生动物造成不良影响。因此，interfering with意为“干扰”，和D项意思相近。故选D。 5 2．Why does Ma patrol Yuncheng Salt Lake every day? A．To serve as a keeper of the lake. B．To observe the rare flamingos closely. C．To admire the scenery around the lake. D．To come across the flamingos again. 解析：细节理解题。根据第二段中的“From that day on ... interfering with the wildlife.”以及“I will do my best to protect the lake”可知，他每天巡逻盐湖是为了阻止人类干扰野生动物、尽力保护湖泊，履行守卫盐湖的职责，即他是作为湖泊管理员每天巡逻盐湖。故选A。 6 3．What can be inferred about Yuncheng Salt Lake from Paragraph 3? A．It is still used as a salt production base. B．The restoration of it will be carried out soon. C．The protection of its ecology is of great importance. D．It's home to 292 types of endangered wildlife. 解析：推理判断题。第三段中的“‘The greatest value of the Salt Lake ... restored and protected”明确指出盐湖最大的价值在于其生态环境，且生态环境的恢复和保护极为重要。由此可推知，对盐湖的生态环境的保护非常重要。故选C。 7 4．Which word can best describe Ma? A．Creative. B．Responsible. C．Generous. D．Humorous. 解析：推理判断题。根据第二段中的“The birds are attracted ... here every year.”以及最后一段中的“After patrolling the lake ... protection in 2019.”可推知，马红义从志愿者到被当地政府雇用，四年多来一直投身于盐湖的野生动物保护工作，始终尽心尽力，这种对保护工作的坚持和担当，体现了他是个很有责任心的人。故选B。 8 B Nearly 6，000 years ago, ancient people climbed the dry, rocky hills in what is now the Nigerian Sahara and carved large images of giraffes into the sandstone. The quite detailed Dabous giraffe rock art is one of many ancient carvings of giraffes found in Africa. We are still attracted to giraffes today, but many of these animals are at risk, largely due to habitat loss and illegal hunting. Giraffes make their homes in many different environments with varied levels of human influence. Each area has unique environmental conditions and protection measures. There is no one­size­fits­all approach to protecting giraffe habitats and promoting harmonious living between giraffes and humans. 9 To understand how giraffes are traveling across Africa, conservation ecologists (保护生态学家) like me are studying how they interact with their habitats across large geographic regions, using space­age technology and advanced statistical (统计学的) approaches that ancient people could have hardly imagined. We have carried out a large giraffe­tracking study to better understand giraffes' movements. Each tracking operation contributes to local studies by telling us something interesting about giraffe behavior. The study is also important for guiding local management of giraffes. We share giraffe location data (数据) in real time with officials in protected areas to guide day­to­day conservation actions. 10 Overall, we've found that on average, each animal has a home range of about 140 square miles and travels about 8.5 miles every day. One of the biggest movers in our study, a female northern giraffe in Niger that traveled among communities raising farm animals in the dry Sahel, covered a home range of nearly 1，500 square miles—larger than the land area of Rhode Island. Giraffes' movements changed significantly based on the supply of food sources and the level of human presence. They tended to move less in places with rich resources or significant human development. They traveled faster and covered larger areas when they were moving between resource­rich areas and more heavily developed areas. 11 Our movement data from giraffes across Africa is throwing new light on their responses to different conditions and providing important information for conserving these unique animals in a rapidly changing world. 篇章导读：本文是一篇说明文。文章介绍了长颈鹿因栖息地丧失与盗猎濒临生存危机，保护生态学家借助高科技追踪研究其活动规律，为制定保护策略提供关键数据。 12 5．Why does the author mention the Dabous giraffe rock art? A．To show the ancients' attraction to giraffes. B．To explain ancient ways of hunting giraffes. C．To describe the ancients' efforts to save giraffes. D．To stress the detail in ancient carvings of giraffes. 解析：推理判断题。根据第一段中的“The quite detailed Dabous giraffe ... and illegal hunting.”可知，这里提到古代的达波斯长颈鹿岩画很细致，是众多古代长颈鹿雕刻之一，且现在人们依然被长颈鹿吸引，是为了表明古人对长颈鹿的喜爱，就如同现在人们对长颈鹿的喜爱一样。由此可推知，作者提到达波斯长颈鹿岩画是为了展示古人对长颈鹿的喜爱。故选A。 13 6．What is Paragraph 2 mainly about? A．Environmental influences on giraffes. B．Challenges in protecting giraffes. C．Human­giraffe relationships. D．Various habitats of giraffes. 解析：段落大意题。根据第二段“Giraffes make their homes ... giraffes and humans.”可知，长颈鹿栖息地多样化且受人类影响程度不同，每个地区情况独特，没有通用的保护方法，这体现了保护长颈鹿存在的挑战。因此，第二段主要介绍了保护长颈鹿面临的挑战。故选B。 14 7．What did the large study find? A．Giraffes can get along with farm animals. B．Giraffes cover impressively large areas. C．Giraffes prefer living in dry areas. D．Giraffes have a sense of home. 解析：细节理解题。根据第五段“Overall, we've found ... of Rhode Island.”可知，研究发现长颈鹿的活动范围变化显著：平均每只长颈鹿的活动范围约为140平方英里，而其中一只雌性北方长颈鹿的活动范围更是接近1，500平方英里，超过了罗得岛的面积。这项大型研究发现长颈鹿的活动范围大得惊人。故选B。 15 8．What is the best title for the text? A．The impact of habitat loss on giraffes B．Studying giraffes based on historical data C．Tracking giraffes across various locations D．A high­tech approach to giraffe conservation 解析：标题判断题。文章先是指出长颈鹿面临生存危机，随后第三段说明保护生态学家研究它们的活动；第四段说明通过追踪研究获取数据并指导保护行动；末段强调该研究为保护长颈鹿提供重要信息。全文围绕“利用高科技手段研究并保护长颈鹿”这一核心展开，因此D项(长颈鹿保护的高科技方法)最适合作为文章标题。故选D。 16 C It is not just the environment and the economy that are threatened by a warmer climate, but also culture and traditions around the world. Researchers at Lund University in Sweden have mapped what little is known about how climate change is gradually destroying local knowledge and cultural heritage. “We risk losing the memory of native people's ways of life without this type of documentation，” says Guy Jackson at Lund University, one of the authors of a literature study. One conclusion of the study is that cultural heritage is primarily seen as something of material value, such as a historic building, and the loss is seen as a potential future problem, even though there is evidence that it is already happening. 17 Focusing on material losses means that important traditions and knowledge systems are overlooked. “There are also many non－material losses that are valuable for both individual identity and group identity，” says Guy Jackson. The study shows a clear connection between loss of native cultural heritage and changes in the natural environment. For example, songs and working methods change when groups lose traditions linked to a physical location. One scientific article points out that identity is closely linked to the environment, “Inuit people (因纽特人) in Canada are people of sea ice. If there is no more sea ice, how can they be people of sea ice？” 18 Loss of traditions and cultural heritage can make it more difficult to deal with climate change, and weaken social togetherness, as people lose touch with traditional ways of life. It also raises the question whether we can expect native people to protect and preserve rainforests and other ecosystems. The researchers hope that the literature study can lead to more targeted research. They want to see a larger focus on how to handle, minimize and tackle future losses. “Science should contribute by developing practical solutions and strategies that help with adaptation to the losses that have already happened，” Guy Jackson concludes. 19 篇章导读：本文是一篇说明文。文章说明了气候变化对文化和传统的影响：它正破坏本土知识与文化遗产，导致传统流失，加剧应对气候难度，研究人员呼吁寻找应对策略。 20 9．What can we learn from the first two paragraphs? A．Climate change causes cultural loss. B．The economy affects the environment. C．Cultural loss is a current problem. D．The native people are being forgotten. 解析：细节理解题。第一段指出气候变暖威胁文化和传统，瑞典的研究指出了气候变化对当地知识和文化遗产的破坏；第二段提到对原住民生活方式的记忆可能消失，且文化遗产流失已经发生。由此可知，前两段的核心是“气候变化会导致文化的损失”。故选A。 21 10．What does the study show about the loss of native cultural heritage? A．It is seriously overestimated by scientists. B．It has brought great damage to Canadians. C．It has transformed global working methods. D．It is closely related to environmental changes. 解析：细节理解题。根据第四段中的“The study shows a ... the natural environment.”可知，本土文化遗产的丧失与自然环境的变化有着密切的联系。故选D。 22 11．What is Paragraph 5 mainly about concerning the loss of traditions and cultural heritage? A．Its natural origins. B．Its negative results. C．Its potential reasons. D．Its effective solutions. 解析：段落大意题。根据第五段“Loss of traditions ... and other ecosystems. (传统和文化遗产的丧失可能使应对气候变化变得更加困难，并削弱社会凝聚力，因为人们失去了与传统生活方式的联系。这也提出了一个问题，我们是否能指望当地人保护和保存雨林和其他生态系统。)”可知，本段主要讲述文化遗产和传统丧失带来的负面后果。故选B。 23 12．What is the main idea of the text? A．The unknown threats to the local knowledge. B．The practical solutions to some cultural issues. C．The climate change's effect on culture and traditions. D．The various losses of important culture and traditions. 解析：主旨大意题。通读全文可知，气候变化不仅威胁环境和经济，还威胁世界各地的文化和传统，而本土文化遗产的丧失与自然环境的变化有着明显的联系。即这篇文章的主旨是“气候变化对文化和传统的影响”。故选C。 24 Ⅱ　七选五 Save the Earth from Declining Biodiversity Plants and animals depend on each other for survival. Find out why this biodiversity is so important and how you can help. Skip the selfie (自拍照).
