It’s true. According to the ISA (International Society of Arboriculture), hospital patients have been shown to recover faster when offered a view with trees. And while trees certainly benefit any landscapes — whether lining residential streets, dotting urban areas, or in full glory in the forest—they are actually important to our daily well-being. Trees improve the quality of the air around us by absorbing dust and other particulates (微粒), and release clean oxygen for you to breathe. If the health of people and the environment aren’t high on your list of concerns, perhaps your wallet is: Trees make economic sense. A home surrounded by trees costs less to cool and heat. Neighborhoods with trees are often several degrees cooler than those in simi-lar climates that don’t have trees. In winter, trees can keep your house warmer by blocking high winds. Also, less water is needed in tree-shaded areas where the sun isn’t constantly boating down on the earth below. Besides, trees can enhance privacy, block unpleasant views, and improve the value of your home. Unfortunately, these days, mass construction projects tend to wipe out all the trees in an area before creating new neighborhoods and buildings. That’s why it’s more important than ever to plant a tree in your community. Check out the NADF (National Arbo r Day Foundation) online to find out more about planting a tree in your area or how to volunteer in an urban center. The Arbor Day Foundation can tell you how to plant a tree in someone’s name as a gift, donate a tree in someone’s honor, or memorialize a loved one by planting a tree. 1．According to the ISA, a sick person in hospital can get well sooner if he or she ________. A．has a glance at some trees B．can enjoy a view of trees C．receives treatment in time D．is surrounded by flowers 2．What does the underlined word “release” mean in Paragraph 3? ________. A．吸收 B．生产 C．传递 D．释放 3．Which of the following is NOT true? ________. A．Trees benefit any landscape as well as human beings. B．Trees take in dust and dioxide and release clean oxygen. C．The health and the environment aren’t on people’s list of concerns. D．People in tree-shaded areas can re-duce their cost on house holding. 4．It is more necessary than ever to plant trees mainly because they ________. A．improve the quality of the air B．make economic profits C．are destroyed for mass construction D．are used to insure privacy 5．________ is most probably mentioned following the last paragraph. A．The website of the NADF B．How to plant a tree C．Importance of planting trees D．How to be a volunteer （B） Bristol Zoo in England closed its doors after 186 years before moving to a new home. Its owner decided to close it in early September of 2022 because of financial (财政的) pressures. Workers at the zoo said they were sad to see it close, but also excited about working at the zoo’s new site (地点) — the Wild Place Project. The new home will be open in 2024. Dr McCabe, an expert at Bristol Zoo, said the move meant the zoo could do more work protecting some of the world’s most endangered animals. She added that the new site would feel much more like the natural habitat (栖息地) of the animals in the wild. The new site was used only for breeding (繁殖) and keeping sick animals for many years. It opened to visitors in 2013 with a large safari park. The 10,000animals at Bristol Zoo were moved to the safari park. Dr McCabe said some of them might find it difficult to get used to the change, but they would enjoy the more natural environment in the end. In 2022, Bristol Zoo held events all summer so that people could share their favorite memories and say final goodbyes on its closing weekend. The zoo’s Simon Garrett said that many families visited the zoo. “It’s not just about the animals. It’s about the memories people have of spending time with loved ones here,” he said. 6．Bristol Zoo closed probably ________. A．because of the ill heath of animals B．because of a drop in animal numbers C．because of the high cost of running D．because of the poor working conditions 7．Which of the following might be Dr McCabe’ s opinion? ________. A．Bristol Zoo was poor at protecting the animals. B．Bristol Zoo did less to breed and keep sick animals. C．The Wild Place Project is a better home for the animals. D．The Wild Place Project is skilled in protecting natural habitats. 8．What does the underlined word “them” in Paragraph 3 refer to? ________. A．The sick animals. B．The animals in the wild. C．The endangered animals. D．The 10,000 animals at Bristol Zoo. 9．What did Bristol Zoo do for visitors before closing? ________. A．It held events all summer. B．It invited visitors to visit for free. C．It shared its favorite memories online. D．It asked many families to share their stories. 10．From the passage, we can learn the following EXCEPT ________. A．where the new site is B．when the old site closed C．when the new site will open D．how large the new site is （C） The Natural History Museum in London holds a yearly contest for the Wildlife Photographer (摄影师) of the Year. Here are some of the best photos and the stories behind them in the year of 2022. Nick Kanakis of the US took this picture of a bird. The bird in the picture had its ear to the ground, listening for insects (昆虫) to catch and eat. Because of this, he won the prize for Bird Behavior. Fernando Belmar of Mexico had to wait in the dark in a cave filled with bats (蝙蝠) and snakes to take this photo. A snake just caught a bat that was flying out of the cave for the night. Finally he won the Amphibian and Reptile Behavior prize. Dmitry Kokh of Russia won the prize for Urban Wildlife. He took the photo of polar bears in an old house on an island in the Chukchi Sea, between Russia and Canada. Kokh was on a boat when he noticed polar bears walking through an area where no one had lived for years. Cactus bees (仙人掌蜜蜂) live underground. Karine Aigner of the United States took the photo when the bees had just come out of their “home”. The “ball” was a lot of male (雄性的) bees fighting to win a female bee. This photo helped Ms Aigner win the Wildlife Photographer of the Year 2022. 11．The text mainly introduces information about ______. A．a museum B．a show C．photos D．environment 12．Why did the bird in Nick’s photo have its ear to the ground? A．Because it was fighting for food. B．Because it was looking for food. C．Because it was walking through the forest. D．Because it was caught by a snake. 13．The photographer who took the photo during the night won ______. A．the prize for Bird Behavior B．the prize for Urban Wildlife C．the Wildlife Photographer of the Year 2022 D．the Amphibian and Reptile Behavior prize 14．Where does the photographer of the polar bears come from? ________. A．The US. B．Mexico. C．Russia. D．Canada. 15．What were the male bees doing in Karine’s photo? ________. A．Playing with a ball. B．Waiting for a female bee. C．Cleaning their “home”. D．Fighting with one another. （D） Nobody knows who invented the pencil or when it was invented. A Swiss (瑞士人) described a pencil in a book in 1565. He said it was a piece of wood with lead (铅) inside it. Pencils weren’t popular, and people continued to write with pens. In 1795, someone started making pencils with graphite (石墨) and they became very popular. Today, people make pencils in the same way. They make the graphite into the shape of a stick, and then they put it inside a piece of wood. One pencil can make a line as long as 55 kilometres. When people first wrote with pens, they had to put the pen point into ink after every few letters. Later someone invented a fountain pen (自来水笔) and this kind of pen could hold ink inside. A fountain pen can write several pages before you have to fill it again. Two brothers, Ladislao and Georg Biro, invented the ballpoint pen (圆珠笔) that we use today. They left their country Hungary and started producing ballpoint pens in England in 1943 during World War Ⅱ. Later, a French company called Bic bought the Biro’s company. Someone calls ballpoint pens bics. Australians call them biros. Whatever we call them, we use them every day. 16．When did the pencil become popular according to the passage? ________. A．In 1565. B．In 1655. C．In 1795. D．In 1943. 17．Who invented the ballpoint pen that we use today? ________. A．Swiss. B．Graphite. C．Ladislao and Georg Biro. D．Bic. 18．Which of the following is TRUE? ________. A．A Swiss invented the pencil in 1565. B．Today people make pencils with graphite. C．A fountain pen can only write one page before you have to fill it again. D．Australians call ballpoint pens bics. 19．Where were Ladislao and Georg Biro from? ________. A．America. B．Australia. C．England. D．Hungary. 20．What is the passage mainly about? ________. A．Some famous inventors. B．The invention of some kinds of pens. C．Who invented the pencil. D．Which kind of pen is the most useful. 原创精品资源学科网独家享有版权，侵权必究！zxxk.com 学科网（北京）股份有限公司 $$ 编写说明：2026版山西省（对口升学）《英语考纲百套卷》，依据最新版《中等职业学校英语课程标准》及历年真题编写。本套试卷共100份：第一部分是42份知识点训练卷，第二部分是单项选择题、完型填空、阅读理解、职业模块分别作答题和书面表达等48份专项训练卷。第三部分是10份综合模拟卷。 本试卷是2026版山西省（对口升学）《英语考纲百套卷》的第69卷，是阅读理解部分专项训练卷。按教学标准的掌握要求编写。 2026版山西省（对口升学）《英语考纲百套卷》第69卷 专项训练卷·共用阅读理解（6）-说明文 考试时间：30分钟 满分：100分 班级 姓名 学号 成绩 1、 阅读理解（共20小题，每小题5分，共100分） 从各题所给的A、B、C、D四个选项中，选出符合题目要求的最佳选项。 （A） Almost everyone loves trees, but did you know that trees can help people heal faster?

A．The website of the NADF B．How to plant a tree C．Importance of planting trees D．How to be a volunteer 【答案】1．B 2．D 3．C 4．C 5．A 【导语】本文是一篇说明文。文章主要讲述了树木对人类健康、环境、经济以及生活质量的多种益处，并呼吁人们种树。 1．细节理解题。根据第二段中“According to the ISA (International Society of Arboriculture), hospital patients have been shown to recover faster when offered a view with trees. (根据ISA（国际树木栽培学会）的研究，医院病人在能看到树的情况下恢复得更快。)”可知，如果医院病人能看到树木，他们会恢复得更快。故选B。 2．词句猜测题。根据第三段中“Trees improve the quality of the air around us by absorbing dust and other particulates (微粒), and release clean oxygen for you to breathe. (树木通过吸收灰尘和其他微粒来改善我们周围的空气质量，并释放干净的氧气供你呼吸。)”可知，树木通过吸收灰尘和其他微粒来改善我们周围的空气质量，并释放出清洁的氧气供我们呼吸，由此可推测出“release”意为“释放”。故选D。 3．细节理解题。根据第三段中“If the health of people and the environment aren’t high on your list of concerns, perhaps your wallet is (如果人们的健康和环境不是你最关心的问题，也许你的钱包是)”可知，人们不是不关心健康和环境，只是可能不是最关心的问题，因此选项C“健康和环境不在人们的关注列表上”表述错误。故选C。 4．细节理解题。根据第四段中“Unfortunately, these days, mass construction projects tend to wipe out all the trees in an area before creating new neighborhoods and buildings. That’s why it’s more important than ever to plant a tree in your community. (不幸的是，如今，大规模建设项目往往会在建立新的社区和建筑之前，把一个地区的所有树木都消灭掉。这就是为什么在你的社区种一棵树比以往任何时候都重要。)”可知，现在种树比以往任何时候都更重要是因为树木因大规模建设而被破坏。故选C。 5．推理判断题。根据最后一段中“Check out the NADF (National Arbor Day Foundation) online to find out more about planting a tree in your area or how to volunteer in an urban center. (上网看看国家植树节基金会（National Arbor Day Foundation），了解更多关于在你所在地区种树或如何在城市中心做志愿者的信息。)”可推知接下来可能会提到NADF的网站。故选A。 （B） Bristol Zoo in England closed its doors after 186 years before moving to a new home.

A．where the new site is B．when the old site closed C．when the new site will open D．how large the new site is 【答案】6．C 7．C 8．D 9．A 10．D 【导语】这是一篇说明文。文章介绍了布里斯托尔动物园是一家拥有186年历史的动物园。2022年9月初，它永久关闭。该园区的一万只动物搬迁至一处野生动物园，该野生动物园将于2024年对游客开放。 6．推理判断题。根据第一段最后一句“Its owner decided to close it in early September of 2022 because of financial (财政的) pressures. (由于财政压力，它的所有者决定在2022年9月初关闭它。)”可知，由于财政压力，其所有者决定关闭该动物园。由此可推测出，布里斯托尔动物园关闭的原因可能是运营成本太高。故选C。 7．推理判断题。根据第二段最后一句“She added that the new site would feel much more like the natural habitat (栖息地) of the animals in the wild. (她补充说，新址更像是野生动物的自然栖息地。)”和第三段最后一句中“but they would enjoy the more natural environment in the end (但它们最终会享受更自然的环境)”可知，McCabe博士认为，新址会更像野生动物的自然栖息地，而且动物们最终会享受在这种更加自然的环境中生活。由此可推测出，野生动物项目是动物们更好的家园。故选C。 8．词句猜测题。根据画线词所在句的前一句“The 10,000animals at Bristol Zoo were moved to the safari park. (布里斯托尔动物园的10000只动物被转移到野生动物园。)”可知，布里斯托尔动物园里的10000只动物被转移到了这个野生动物园，故此处指这10000只动物中的一些可能会发现很难适应这种改变，故画线词“them”指代的是上一句中提到的“布里斯托尔动物园里的10000只动物”。故选D。 9．细节理解题。根据最后一段中“In 2022, Bristol Zoo held events all summer (2022年，布里斯托尔动物园整个夏天都在举办活动)”可知，布里斯托尔动物园整个夏天都在举办活动。故选A。 10．细节理解题。第一段中“Its owner decided to close it in early September of 2022 (它的所有者决定在2022年9月初关闭它)”可知，文章提到了布里斯托尔动物园关闭的时间。第二段中“the zoo’s new site (地点) — the Wild Place Project (动物园的新址——荒野项目)”和“The new home will be open in 2024. (新馆将于2024年开放。)”分别提到了动物园的新址和新址开放的时间。文中未提及D项“新址有多大”。故选D。 （C） The Natural History Museum in London holds a yearly contest for the Wildlife Photographer (摄影师) of the Year.
