the evening， I drink a cup of tea and watch the stars.I think about㉘ the antelopes and [11]what Zhaxi told me.Much [12]is being done to protect wildlife， but if we really want to save the planet， we must change our way of life.[13]Only when we learn to exist㉙ in harmony㉚ with nature can we stop being a threat to wildlife and to our planet. 　　[10]since引导原因状语从句，表示“因为”。 　　[11]what引导宾语从句和the antelopes一起作think about的宾语。 　　[12]is being done是现在进行时的被动语态，表示正在进行的被动动作。 　　[13]“only＋状语从句”位于句首表示强调时，后面的主句要用部分倒装，即把助动词、情态动词或连系动词be提到主语前面。 ①snow-covered adj.被雪覆盖的 ②disappear into ...消失在……中 ③plain

　　由于空气稀薄，在离开营地的短途徒步旅行中，我们不得不多次休息。在我们的左边，白雪皑皑的群山消失在似乎触手可及的云层中。放眼平原，我们隐约看到一群体形优美的动物。这就是我们来到此地的原因——观察藏羚羊。 　　藏羚羊生活在西藏、新疆和青海的平原上。看着它们（藏羚羊）缓缓穿过绿色的草地，我被其美丽震撼，也意识到了它们曾经所处的险境。因其珍贵的羊毛，它们（藏羚羊）曾遭受非法猎杀。 　　我的向导扎西是一位来自羌塘的村民。扎西在羌塘国家自然保护区工作。该保护区是西藏西北部动植物的庇护所。对扎西来说，这片土地是神圣的，保护野生动物是一种生活方式。“我们不是在试图拯救动物，”他说道，“事实上，我们是在努力拯救自己。” 　　对藏羚羊来说，二十世纪八九十年代是悲惨的时代。藏羚羊数量减少了50％以上。猎人们为了谋利而射杀它们。随着新公路和铁路的修建，它们的栖息地不断缩小。 　　为了使这一物种免遭灭绝，中国政府将其置于国家保护之下。扎西和其他志愿者日夜看护着藏羚羊，保护它们免受攻击。新增的一些桥梁和涵洞，便于藏羚羊自由穿行，防止它们撞上汽车和火车。 　　这些措施效果明显。藏羚羊数量已经恢复，2015年6月，藏羚羊从濒危物种名单中移除。然而，政府并没有打算停止这些保护项目，因为对藏羚羊的威胁依然存在。 　　夜晚时分，我喝着茶，仰望星空。心里想起藏羚羊以及扎西对我说的那番话。在野生动物保护方面尽管我们正在做大量工作，但是，如果真想拯救地球，就必须改变我们自己的生活方式。只有学会和大自然和谐共处，我们才不会成为野生生物和地球的威胁。 Ⅰ.词块默写 1.　snow-covered mountains　 白雪皑皑的群山 2.　place ...under protection　 　　将……置于保护之下

　　（2025·宿州示范高中高一期末） Wildlife Conservation Volunteering 　　Wildlife conservation volunteering plays an important role in protecting endangered species like elephants from extinction due to habitat loss.Opportunities at rescue centers or reserves involve caring for injured wildlife， monitoring species for research， and anti-poaching （反偷猎） efforts. 　　Join us and you can make a difference and help preserve biodiversity！ 　　· Best Places to Volunteer 　　Africa 　　If you want to experience African wildlife from up close， look at South Africa， Kenya， or Namibia for volunteer projects.Not only do they offer a great amount of wildlife on land， but some of them are also home to many sea creatures. 　　Latin America 　　If you are interested in volunteering with primates （灵长类动物） in their jungle habitats， look no further than Central and South America.Peru， Brazil and Ecuador all share parts of the Amazon rainforest. 　　· Who Can Volunteer？ 　　As long as you are willing to learn and treat the wild creatures with the necessary respect and caution， you are more than welcome to volunteer.It doesn’t matter if you have any related working experience before. 　　You need to speak at least basic English， the main language spoken at most projects.Some projects in Latin America will ask you to speak basic Spanish. 　　Besides， volunteer projects working with wild and more dangerous animals accept volunteers aged 18 but there is no age limit upwards — as long as you are physically fit and ready for a challenge， you are the perfect person to volunteer.

B.They have a special diet. C.They avoid human contact. D.They attack people sometimes. 解析：C　细节理解题。根据第一段第二句可知，安第斯熊避免与人接触让研究安第斯熊变得困难。 9.What was a finding about Andean bears through GPS-enabled cameras？（　　） A.They ate up all the bromeliads. B.They foraged outside the national park. C.They were very picky about their food. D.They were short of food in the dry season. 解析：C　细节理解题。根据第二段内容可知，GPS摄像头发现安第斯熊对食物很挑剔。 10.What can be inferred from paragraph 3？（　　） A.Andean bears are highly adaptable. B.Andean bears have recovered lost habitats. C.Livestock are mainly from cloud forests. D.Livestock are in harmony with Andean bears. 解析：A　推理判断题。根据第三段最后一句可推知，安第斯熊的适应能力很强。 11.What is the problem with the collars according to the researchers？（　　） A.They waste a lot of power. B.They do harm to bears’ health. C.They cannot provide data at night. D.They don’t work in cold temperatures. 解析：C　细节理解题。根据最后一段倒数第二句可知，根据研究人员的说法，项圈在夜间不能提供数据。 D 　　（2025·三明高一期末）This past summer， a turtle （海龟） was freed after making an unexpected nearly one-year-long recovery fighting.Solaria had been hit and completely pressed by a running car in Montauk， suffering several fractures （骨折）， and was rescued and named by the Turtle Rescue of the Hamptons. 　　The Turtle Rescue of the Hamptons is a turtle recovery center located on the North Fork of Long Island.When Solaria was first sent to the center， it was Dr.Turetski who gave her some first-aid.“Dr.Turetski majors in emergency aid when the animal cannot be immediately taken to a wildlife center，” Jennifer Faga， local wildlife rescuer， said.“He has his own practice and works on animals in serious situations like this one.” 　　After being treated by Dr.Turetski for a short period of time， Solaria was sent to the Turtle Rescue of the Hamptons， and recovered with the rescue for almost a year until this summer， when she finished her recovery and was successfully freed. 　　“It’s really important to take care of these guys because they take care of our ecosystems，” said Testa， director of the centre.“Turtles are both a marker and a key species.” Being the former means that turtles are affected by the chemicals left on the ground， while being the latter means that the ecosystem around such species is dependent on it.Turtles spread seeds， fertilize the ground， which makes the earth more productive， clean the water， and preserve health around their ecosystem. 　　“Turtles can live for 40－60 years， yet on Long Island， turtles are in danger.Like Solaria， they are often hit by cars， so many of their lives are cut short，” Testa said.“To help stop situations like Solaria’s from happening again， if you see a turtle crossing the road， pick it up and place him away from the road whenever possible.” 语篇解读：本文是一篇说明文。文章主要讲述了海龟Solaria的救援与恢复过程及其生态重要性。 12.What happened to Solaria？（　　） A.It was hit by a truck. B.It was injured seriously. C.It was named by its owner. D.It took him over a year to recover. 解析：B　细节理解题。根据第一段第二句可知，Solaria受了重伤。 13.Which of the following can best describe Dr.Turetski？（　　） A.Talented.　 B.Responsible. C.Warm-hearted.　 D.Professional. 解析：D　细节理解题。根据第二段内容可知，当Solaria第一次被送到救援中心时，是Turetski医生给它进行了急救，并且Turetski医生专门研究在动物无法立即被送到野生动物中心时的紧急援助。由此推知，Turetski医生非常专业。 14.What does the underlined word “fertilize” in paragraph 4 mean？（　　） A.Measure.　 B.Destroy. C.Enrich.　 D.Enlarge. 解析：C　词义猜测题。根据第四段最后一句可知，此处应该是指海龟对土地有积极作用，使土地更加肥沃。因此fertilize意为“使肥沃，丰富”。 15.In the last paragraph， Testa aims to 　　　　.（　　） A.give an example B.give a solution C.make an arrangement D.make an impression 解析：B　推理判断题。根据最后一段最后一句可推知，Testa旨在提出一个解决方案，以防止像Solaria这样的情况再次发生。 Ⅱ.阅读七选五 　　（2025·南平高一检测）Now is a great time of year to take a hike.The weather is cooler and trees may be just beginning to change color.16.（　　） Here’s how. 　　Get prepared. 　　17.（　　） Add an extra layer of clothing， such as a light jacket， that you can put on and take off as needed.Take a backpack that you can use to carry a hat， water and some snacks.You could also pack extras， such as a pencil and notebook for drawing. 　　Add excitement. 　　To get your group to take notice of nature on your walk， you could make a list of items to look for.Your list could include different flowers and mushrooms.At the start of the hike， share copies of the list with pencils.As hikers find the items， they cross them off their list.18.（　　） 　　19.（　　） 　　If you see flattened plants， it may be a sign that an animal was recently resting there.Animal tracks， feathers， nests， and animal droppings are also signs that animals live in the area.If your hike takes you near a stream or lake， you may be more likely to see animals， since many like to be near a water source. 　　Tread （踏） lightly. 　　One of the main rules of spending time in nature is to “leave no trace”.20.（　　） Carry out all your rubbish， and don’t take any leaves， flowers or branches from trees or bushes.You want to keep them there for the wildlife and other hikers to enjoy. A.Stay away from dangers. B.Search for signs of animals. C.You’ll want to wear mountain climbing shoes. D.The goal is to be the person who finds the most items.

16.G　上文提到现在是徒步旅行的好时节，天气凉爽且树木开始变色，下文介绍了徒步旅行的一些方法，G项（选择一个周末，邀请你的家人和朋友去徒步旅行）起到承上启下的作用，引出下文关于徒步旅行的准备等内容。 17.C　根据Get prepared.以及下文可知，本段在介绍徒步旅行的准备工作，C项（你会想穿登山鞋）也是准备工作的一部分，符合语境。 18.D　根据上文可知，这是一个寻找物品的活动，D项符合这个活动的情境，上下文紧密连接。 19.B　根据下文可知，这部分主要讲的是寻找动物的踪迹，B项能总结该段内容，作为该段小标题合适。 20.F　根据上文leave no trace可知，F项符合语境，解释了上文“不留下痕迹”的含义，引出下文具体做法，F项中的This指代上文leave no trace。 核心词汇集释 1.observe

B.Cover their cages with sea grass. C.Feed tiny shrimp to them monthly. D.Prepare underwater habitats for them. 解析：D　细节理解题。根据第五段内容可知，科学家们为了帮助小海马生存，在它们被放归前大约一个月，为它们建造了8个水下“旅馆”，为海马提供了一个安全的生长场所，即准备了水下栖息地。 3.What made the seahorse release unique？（　　） A.The timing of the release. B.The number of seahorses released. C.The location of the release. D.The survival rate of pregnant seahorses. 解析：B　细节理解题。根据第六段第一、二句可知，科学家们已经在该地区放归了五次海马，但这次放归数量达到了约380只，创下了纪录，所以这次放归的独特之处在于放归海马的数量。 4.How does Brett Fenton sound in the last paragraph？（　　） A.Curious.　 B.Confident. C.Confused.　 D.Concerned. 解析：B　推理判断题。根据最后一段中Brett Fenton说的We have high expectations that we’ll see the animals do well over the next 12 months.可推测，Brett Fenton对这些被放归的海马未来的成长和繁殖充满信心，所以他的语气是自信的。 B 　　（2025·日照高一期末）In a remote part of Ecuador’s Amazon rainforest， river transport is far more common than road travel.Here， boats move along the Wichimi River， a wide channel that snakes through the thick plants， and powering the silent boats is the Ecuadorian sunshine. 　　The boats have been provided by Kara Solar， a non-profit organization based in the region.The Achuar here are responsible for fixing， running and maintaining the boats — the solar boats are shaping daily life for the community by offering transport for education， health services and eco-tourism. 　　For years， many Achuar have used gasoline-powered boats on the river， but the oil must be flown in by plane from Ecuador’s capital， Quito， making it more expensive and adding to the carbon emissions （碳排放） connected with its use.“Gasoline motors use a lot of oil and pollute the river，” said Angel Wasump， Kara Solar’s director of operations and a member of the Achuar community.“Since the solar boats arrived， families have been giving up these motors completely，” he added. 　　Formally launched in 2018， Kara Solar is staffed by members of the Achuar community.According to the organization， the boats operating in Ecuador have completed over 300 trips in total， carrying over 1，000 passengers and traveling over 450 kilometers per month.The most common uses are transporting local children to and from school and providing wildlife tours for eco-tourists. 　　As well as reducing carbon emissions and pollution， the silent boats mean eco-tourists can get a closer view of wildlife without scaring it away.“The boat serves as a symbol of what eco-friendliness could look like，” said Wasump.“It’s like a return to what’s most important in Achuar culture.These boats have represented a way for us to reconnect with this vision of what development could look like.” 语篇解读：本文是一篇说明文。文章主要介绍了在厄瓜多尔亚马孙雨林的一个偏远地区，卡拉太阳能公司为当地阿查乌族社区提供了太阳能船，代替了以前使用汽油发动机的船。太阳能船不仅减少了碳排放和污染，还让游客能够更近距离地观察到野生动物。 5.What can we learn about the Achuar from the first two paragraphs？（　　） A.They mostly earn their living by fishing.
