That's like having 634 cans of soda and 1，200 hamburgers every day. This keeps them moving thousands of miles across Africa each year. Elephants usually migrate between March and May. Females live in groups with their children, and quickly run out of the food supply. They hit the road in search of food. Male elephants live alone, so they don't use resources as quickly as the females. Instead, they migrate during their mating cycle. When the females pack their trunks, so do the males. 课后课时作业 42 During migration, elephants face short water supplies and extremely high temperatures. But people are their number­one problem. Poachers (偷猎者) kill 35，000 elephants each year for ivory. Many African farmers build fences (栅栏) to protect crops and cattle, which might block regular migration paths. Traffic roads affect elephant migration, too. During one study of 28 elephants in Central Africa, only one female crossed an unprotected road. Scientists, wildlife organizations and governments cooperate to find solutions for Africa's elephants. “To unlock the secret of where elephants move and how they move, we place collars (项圈) with a satellite unit inside，” Dr Michael Chase says. GPS collars help map which routes elephants use most so that countries can establish protected elephant passages. 课后课时作业 43 篇章导读：本文是一篇说明文。文章主要介绍了多方合作利用GPS追踪技术并携手当地社区，共同保护大象迁徙路线以助其生存。 Locals come in as well. James Isiche, East Africa Director of the International Fund for Animal Welfare says, “We have got the community on our side by a project; they've agreed to partner with us to conserve elephants.” The local community run wildlife parks to attract tourists. “This project helps us take care of both the wildlife and our cows，” says Sikira, a tribal elder in Maasai, Kenya. Protecting elephant migration routes allows these gentle giants to survive. 课后课时作业 44 1．What can we learn about the elephants from Paragraph 1? A．They show an interest in hamburgers. B．They move south to survive the cold. C．They migrate for different reasons. D．Females live shorter for food shortage. 解析：细节理解题。根据第一段中的“Females live ... mating cycle.(雌性大象与其幼仔群体生活，它们的食物资源会迅速耗尽。它们出发去寻找食物。雄性大象则独自生活，它们不像雌性大象那样快速消耗资源。相反，雄性大象会在繁殖周期时进行迁徙。)”可知，大象迁徙的原因各不相同。故选C。 课后课时作业 45 2．What is Paragraph 2 of the text mainly about? A．Results of poaching. B．Reasons for killing elephants. C．Difficulties in migrating. D．Efforts to protect migration paths. 解析：段落大意题。根据第二段内容可知，本段主要讲述了大象在迁徙过程中会面临缺水、高温、被猎杀、路线受阻等困难。故选C。 课后课时作业 46 3．Why are collars applied by scientists? A．To discover the secret of migration. B．To track elephants with technology. C．To identify the population of elephants. D．To explore a new route for migration. 解析：细节理解题。根据第三段中的“To unlock ... Dr Michael Chase says. (Michael Chase (迈克尔·蔡斯)博士说：‘为了解开大象在哪里移动以及如何移动的秘密，我们在项圈里放置了卫星装置’。)”可知，科学家使用项圈是为了用技术追踪大象。故选B。 课后课时作业 47 4．What is the best title for the text? A．Say No to Ivory B．A Journey in Africa C．Ready for the Move D．Technology in Migration 解析：标题判断题。文章主要介绍了为保障大象的迁徙，多方合作利用GPS追踪技术并携手当地社区，共同保护大象迁徙路线以助其生存，C项(为迁徙做好准备)最适合作为文章标题。故选C。 课后课时作业 48 B The dry land in Gir National Park and Wildlife Preserve, located near India western tip, is the proud—and only—home of the Asiatic lion. By the early 1900s, however, their populations had decreased for home loss and hunting, leaving fewer than 50 known individuals alive. Though their numbers have risen over the past several decades, the lions are still considered endangered. One of the biggest challenges to keep the lions' future is to track them, a hard work. Some animals, like tigers and zebras, have special coat patterns (图案) that provide useful marks to the researchers. But for the Asiatic lions, researchers must look elsewhere. 课后课时作业 49 Banerjee, who worked for Indias National Tiger Conservation Authority, developed an AI system to recognize the lions with high accuracy (精准). The AI program, SIMBA, has been applied in practice. “It will be a fantastic tool for long­term lion monitoring，” says Banerjee. He adds, “It could help forest officials arrive at a more accurate estimate (评估) of Gir's lion population. In a few years, the group will have a rich collection of information—how many lions are male, female, how many will bear babies and how many are dead.” 课后课时作业 50 篇章导读：本文是一篇说明文。文章主要介绍了一个有助于保护濒危亚洲狮的人工智能项目。 Despite the advantages, Banerjee also adds his worries. He suggests certain rules be made to prevent main information from being stolen. “Where tools like SIMBA really shine，” he says, “is in helping researchers develop monitoring plans that are keys to the protection of at­risk animals，” he says, “otherwise, all your efforts will be in vain.” 课后课时作业 51 5．What is the greatest difficulty in protecting Asiatic lions? A．Stopping them from being killed. B．Keeping track of them. C．Protecting their living environment. D．Increasing their population. 解析：细节理解题。根据第二段中的“One of the biggest challenges to keep the lions' future is to track them, a hard work.(要想保住狮子的未来，最大的挑战之一就是追踪它们，这是一项艰巨的工作。)”可知，保护亚洲狮最大的困难是追踪他们。故选B。 课后课时作业 52 6．How does SIMBA help researchers? A．By locating lions' homes. B．By tracking other animals. C．By monitoring the animal stealers. D．By providing accurate information. 解析：细节理解题。根据第三段中的“He adds ... how many are dead.(他补充说：‘这可以帮助森林官员更准确地估计吉尔的狮子数量。几年后，该组织将收集到丰富的信息——有多少狮子是雄性的，有多少是雌性的，有多少会生育，有多少会死亡。’)”可知，SIMBA通过提供准确的信息帮助研究人员。故选D。 课后课时作业 53 7．What's Banerjee's opinion about the AI program? A．It needs to be widely used. B．It has saved the at­risk animals. C．Its possible risks should be aware of. D．Its disadvantages should be ignored. 解析：推理判断题。根据最后一段中的“Despite the advantages ... information from being stolen. (尽管有这些优势，Banerjee (班纳吉)也继续说出了他的担忧。他建议制定一些规则来防止主要信息被盗。)”可推知，Banerjee对人工智能项目的看法是应该意识到它可能存在的风险。故选C。 课后课时作业 54 8．Which can be a suitable title for the text? A．The Application of AI on Protecting Animals B．The AI Program for the Endangered Asiatic Lions C．The Measures of Protecting Asiatic Lions D．The Biggest Challenge of the AI system 解析：标题判断题。通读全文可知，本文主要介绍了一个有助于保护濒危亚洲狮的人工智能项目。故选B。 课后课时作业 55 Ⅱ　七选五 Should We Create More National Parks to Save Endangered Animals? Don't you find it worrying that more and more species of animals are in real danger of becoming extinct? __1__ And I think the best way to do this is for governments to create more national parks. __2__ If this environment is destroyed—for example, when farmers clear a forest for new fields, or trees are cut down to make profits—many animals are unable to survive, and more species are likely to become extinct. 课后课时作业 56 In addition, national parks protect animals from the danger of being hunted. A major reason why many species are endangered is that these animals are killed by hunters. They hunt animals to make money. __3__ On the other hand, some people fight against the creation of national parks because they consider it is wrong to interfere with nature. They believe that wild animals are happier living in their natural environment. __4__ They also point out that a few species are more likely to produce young animals in the wild than in national parks. All in all, these disadvantages are far less important than the benefits of national parks. __5__ As a matter of fact, they protect animals from their greatest enemies, that is, human beings. 课后课时作业 57 篇章导读：本文是一篇议论文。文章主要论述了作者支持建立更多的国家公园来拯救濒危动物及其原因。 A．To begin with, animals are important to humans. B．Some hunters even hunt animals simply for sport. C．I personally believe that we must save these animals. D．These parks allow animals to live in a safe environment. E．Firstly, national parks protect these animals' natural environment. F．They say though the animals may face danger, they enjoy a free life. G．There is a heated discussion about whether to create more national parks. 课后课时作业 58 解析：上文“Don't you find ... of becoming extinct？”提出问题，表明作者对动物物种灭绝很担忧。C项(我个人认为我们必须拯救这些动物。)承接上文，表明作者对上文问题的看法。故选C。 1．答案：C 解析：下段首句“In addition ... of being hunted.”提出了国家公园的另一个优点。由此可推知，设空处应为国家公园的第一个优点，E项(首先，国家公园保护这些动物的自然环境。)符合语境。故选E。 2．答案：E 课后课时作业 59 解析：上文“A major reason ... to make money.”介绍物种灭绝的一个原因是猎人为了赚钱。B项(有些猎人甚至只是为了消遣而捕猎动物。)承接上文，介绍猎人猎杀动物的又一个原因。故选B。 3．答案：B 解析：上文“They believe that wild animals are happier living in their natural environment.”指出一些人认为野生动物生活在自然环境中更快乐。F项(他们说，尽管这些动物可能面临危险，但它们享受着自由的生活。)承接上文，与上文构成并列关系，说明一些人反对建立国家公园的原因。故选F。 4．答案：F 课后课时作业 60 解析：上文“All in all ... national parks.”再次重申作者的观点，支持通过国家公园来保护濒危动物。D项(这些公园允许动物生活在一个安全的环境中。)承接上文，与上文构成因果关系。故选D。 5．答案：D 课后课时作业 61 Two years ago Lucy was saved from a rural area in New South Wales, Australia. Today, she is one of the lucky animals living in rows of trees that have been planted to protect koalas and other animals by saving their smaller and smaller habitat, or natural environment. 精深阅读 课后课时作业 62 The trees, planted by the local protection group Bangalow Koalas, are made up of large systems of plants. They are a lifeline for koalas and other animals. All of them are in danger of dying out, or at risk of extinction. The trees provide a safe way across the koala's increasingly broken habitat. This protects koalas from human threats. “Our trees are actually trying to get them away from humans, cars and dogs，”said Linda Sparrow, president of Bangalow Koalas. The koala is expected to die out in the wild in New South Wales by 2050. Some of the biggest threats include wildfires and habitat loss through land clearing for development. 课后课时作业 63 Bangalow Koalas has planted over 336，000 trees on 119 areas, helping koala protection and improving the local ecosystem. The group, which depends on community volunteers, aims to plant 500，000 trees by 2025. “The neighbor would want to join and then another neighbor would want to join，” Sparrow said. Volunteer Lindy Stacker, who has been planting trees for over five years, still remains devoted to the cause. A recent report by the Australian Koala Foundation said the animal was worth about $3.2 billion per year to the tourism industry. However, the World Wildlife Fund-Australia reported a drop in koala populations in Australian states. “I can't imagine a world where there's no koalas in the wild，” Sparrow said. “We're going to do our best to make sure that doesn't happen.” 课后课时作业 64 篇章导读：本文是一篇说明文。文章主要介绍了澳大利亚的考拉和其他一些动物都面临着濒临灭绝的危险，当地保护组织正在尽自己最大的努力采取措施保护这些野生动物。 课后课时作业 65 1．Why is Lucy mentioned in Paragraph 1? A．To show it is important to plant trees. B．To suggest a way to protect nature. C．To introduce a special kind of living thing. D．To compare koalas with other animals. 课后课时作业 66 解析：推理判断题。根据第一段中的“Today, she is one of ... natural environment.(如今，它是生活在一排排树木中的幸运动物之一，这些树木是为了保护考拉和其他动物，拯救它们越来越小的栖息地或自然环境而种植的。)”和第二段中的“They are a lifeline for koalas and other animals.(它们是考拉和其他动物的生命线。)”可知，Lucy (露西)因种植的树木而幸存下来，种植树木起到了保护考拉和其他动物的作用，树木成了这些动物的生命线，由此可推知，第一段提到Lucy是为了表明种植树木的重要性。故选A。 课后课时作业 67 2．What does the underlined word “extinction” probably mean in Paragraph 2? A．Growing. B．Disappearing. C．Reducing. D．Failing. 解析：词义猜测题。根据画线词前的“All of them are in danger of dying out (它们都有灭绝的危险)”和连词or可知，extinction与dying out意思相同，表示“灭绝，消失”。故选B。 课后课时作业 68 3．How does Sparrow feel about koalas' future? A．Doubtful.
