Best for a national park pilgrimage：Banff Canada’s first national park，Banff sits in the palm of the snow-dusted Rocky Mountains and has drawn travellers to its natural hot springs since it first opened in 1885.Those mineral baths also inspired the construction of the Fairmont Banff Springs Hotel，a 135-year-old，Scottish baronial-style castle.The action here centres around the skiing town of Banff，but the mountains are home to wildlife such as moose and grizzly bears. Best for wildlife：Jasper Banff’s northern，lesser-visited neighbour，Jasper，is double its size and the largest national park in the Canadian Rockies.A hiker’s region of wild peaks，it’s hard not to bump into wildlife here.Elk，big horn sheep，and wolves are abundant.Time your visit for spring or autumn when wildlife-watching is at its peak.Non-hikers can enjoy cable-rides for valley views and star-gazing at night—Jasper is the second-largest Dark Sky Preserve，in the world. 　　语篇解读　本文是一篇应用文。文章主要介绍了加拿大四个适合户外探险的地方，分别介绍了它们各自的特色和吸引力。 1.What makes Gros Morne National Park attractive geologically？ A.The availability of camping.　 B.The Tablelands，an ancient plateau. C.The presence of natural hot springs.　 D.Its location in Newfoundland and Labrador. √ 细节理解题。根据Best for geological wonders：Gros Morne部分中“The park’s calling card is an ancient treasure—the Tablelands，a plateau pushed up by tectonic (地壳构造的) plate shifts and one of only a few places in the world you can walk on the earth’s mantle (地幔).”可知，从地质学角度来说，Tablelands，这个古老的高原使得格罗斯莫恩国家公园具有吸引力。故选B项。 2.Where can you find a family-friendly camping option in Ontario？ A.In Banff National Park.　 B.In Jasper National Park. C.In Thousand Islands Park.　 D.In Gros Morne National Park. √ 细节理解题。根据Best for soft adventure：Thousand Islands部分中“One of Canada’s smallest national parks...camping—a popular，family-friendly option here.”可知，在安大略省的千岛湖公园可以找到适合家庭的露营选择。故选C项。 3.What do Banff and Jasper have in common？ A.Their hot season is spring.　 B.Their hot springs attract tourists. C.They have a history of over 100 years.　 D.A wide range of wildlife can be found there. √ 细节理解题。根据Best for a national park pilgrimage：Banff部分中“The action here centres around the skiing town of Banff，but the mountains are home to wildlife such as moose and grizzly bears.”以及Best for wildlife：Jasper部分中“A hiker’s region of wild peaks，it’s hard not to bump into wildlife here.Elk，big horn sheep，and wolves are abundant.”可知，在Banff和Jasper都能发现各种各样的野生动物。故选D项。 B (2025·陕西省咸阳市高二上学期期末) Every year，travelers head to South America to be amazed at the vast glaciers，huge open skies and high mountains.But at Omora Ethnobotanical Park on Tierra del Fuego，visitors are encouraged to think small. Tierra del Fuego，a remote island at the tip of South America，might offer little in terms of animals and trees，but when it comes to bryophytes (苔藓植物)，it is among the richest corners of the planet.In the area that covers less than 0.01％ of the Earth’s land surface，more than 5％ of the world’s bryophyte species is found. On entering the park，you’re given a magnifying lens (放大镜).Guided by plant experts，you are invited to get down on your hands and knees to explore the little-known world of Tierra del Fuego’s “miniature forests”—the bryophytes that cover the rocks and trees.Focus is key：as you tiptoe through the park，it is easy to miss or even step on them. I wondered how interesting mosses could be.But when I got up close，they started to come to life.Shapes and colours appeared that were not visible to the naked eye.One plant was bright yellow，while another was green with a bright red tip like a little hat. One of the strangest plants is Old Man’s Beard，which looks like thin noodles and hangs off the trees in webs.According to my guide Lily Lewis，it plays an important role in the growth of the forest，capturing nutrients (营养) and salts blown in on the ocean wind. Old Man’s Beard is extremely vulnerable to pollution，and has all but disappeared across much of the planet.But in Tierra del Fuego，where the air and rain are among the cleanest on the planet，it grows wildly. “The hand lens is your entry point into the world of the miniature forests，” Lewis said.“Looking through a lens reminds you that there are other viewpoints from which we can see the world.” 　　语篇解读　本文是一篇说明文。文章主要介绍了位于南美洲最南端的火地岛上的一个民族植物学公园，这里拥有丰富的苔藓植物资源。文章详细描述了游客在公园内的体验，包括使用放大镜观察苔藓植物的细节，以及苔藓植物中一种奇特的种类——Old Man’s Beard的作用和生长环境。 4.Which title best describes Tierra del Fuego？ A.A top destination for hiking lovers.　 B.A unique place for rare species. C.A wonderland for tiny plants.　 D.A remote land with modern buildings. √ 推理判断题。根据文章第二段内容可知，文章主要围绕火地岛展开，重点介绍了火地岛在苔藓植物(苔藓及其他小型植物)方面的丰富性。文中提到在这片仅占地球陆地面积不到0.01％的区域内，却拥有世界上超过5％的苔藓植物物种。故选C。 5.What quality is highly valued while exploring Omora Ethnobotanical Park？ A.Curiosity and creativity.　 B.Calmness and attentiveness. C.Quickness and confidence. D.Determination and courage. √ 细节理解题。根据文章第三段“Focus is key：as you tiptoe through the park，it is easy to miss or even step on them.”可知，在植物园探索时，专注是关键，因为一不小心就可能错过这些苔藓植物甚至踩到它们。这意味着需要保持专注，同时在园内行走需要小心翼翼，要保持一种沉稳的状态。故选B。 6.Which can best replace the underlined word “vulnerable”？ A.Sensitive. B.Adaptable. C.Beneficial. D.Resistant. √ 词义猜测题。根据画线单词所在句“Old Man’s Beard is extremely vulnerable to pollution，and has all but disappeared across much of the planet.But in Tierra del Fuego，where the air and rain are among the cleanest on the planet，it grows wildly.”可知，Old Man’s Beard在地球大部分地区几乎消失，而在空气和雨水最洁净的火地岛却肆意生长，说明它对污染的反应很强烈，受污染影响很大，很容易因污染而难以生存。由此可知，画线单词和选项A Sensitive“敏感的”意思相近。故选A。 7.What does this passage mainly talk about？ A.The eco-tourism in Tierra del Fuego. B.The disadvantages of bryophytes. C.The smallest island in South America. D.A tiny forest on the tip of the world. √ 主旨大意题。根据文章内容可知，文章开篇指出在火地岛的奥莫拉民族植物公园鼓励游客关注微观世界，接着说明火地岛虽在动物和树木方面不突出，但苔藓植物丰富，是地球上苔藓植物物种丰富的地区之一。然后描述了进入公园后用放大镜探索由苔藓植物构成的 “微型森林”，介绍了其中一些奇特的植物如Old Man’s Beard等，强调了这些苔藓植物的独特以及在火地岛的生长情况，整体围绕火地岛的“微型森林”展开。故选D。 Ⅱ.阅读七选五(每小题2.5分，共12.5分) (2025·吉林省四平市高二下) What if we take a closer look at the food chains in a garden？ 　1　 Or how，as we put it in another way，everything gardens. I began by looking at which larger predatory (捕食性的) creatures are in my garden.Some predators are at the tops of the food chains.Others，of course，can be both predators and prey (猎物).　2 .　 Working out the place occupied by various wildlife in my garden comes next.With most creatures in the garden，including common pests (有害动物)，the key to successfully living with them and preventing population explosions lies in understanding what they eat and what eats them，that is，their place within garden food chains.We also need to understand that there will never be just one food chain in operation. 　3　 Just think of the number of different things that will eat different insect species. Looking at who is eating what，when，and where in our gardens can help us not only understand our gardens better but also get them to function better and find our own place as a gardener within the systems. 　4　 While these creatures are sometimes considered pests，they are extremely beneficial to keep the ecosystem in balance. Seeing connections with an open mind can help a gardener understand nothing in the world works on its own.　5 . A.Why should we work out what eats what in a garden？ B.The interdependence between garden creatures is limited. C.Different creatures will compete over various forms of prey.
