They mainly feed on fresh bamboo. A baby panda is tiny and weak after birth, so it needs its mother’s careful care for months. Years ago, pandas faced great danger. Their natural home — bamboo forests were destroyed by human activities. As a result, the number of wild pandas dropped sharply. To save pandas, China built many nature reserves. In these protected forests, pandas can find enough bamboo and live in quiet safe conditions. Scientists also study panda life habits. They do research on panda breeding and share useful experience with foreign wildlife groups. Thanks to long‑term protection work, the number of wild pandas is growing slowly. Pandas are no longer on the global endangered list. However, protection work cannot stop. Human beings should keep protecting their forest home. Every small effort counts for wildlife protection. ( )1. What do pandas mainly eat? A. Bamboo. B. Meat. C. Grass. D. Fruit. ( )2. Why did the number of wild pandas drop greatly years ago? A. They had too many babies. B.They could not sleep well. C. The weather became too cold. D. People destroyed their forest home. ( )3. What did China do to protect pandas? A. Moved all pandas to big cities. B. Fed pandas only man‑made food. C. Built many nature reserves. D. Cut down all bamboo forests. ( )4. The underlined word “reserves” in Paragraph 2 means ____. A. 保护区 B. 动物园 C. 农场 D. 博物馆 ( )5. What can we infer from the passage? A. We can stop protecting pandas right now. B. Panda protection still needs our continuous efforts. C. Pandas can live well without bamboo. D. All wild pandas now live in city zoos. (二) Fresh clean water is precious natural resource. Though about 70 percent of the earth’s surface is covered with water, most of it is salty sea water. Only a very small part is usable fresh water for human life. So saving water becomes necessary for every family. There are many easy ways to save water in daily life. Turn off the tap tightly when you brush your teeth. Do not let running water waste while washing hands. We can collect rainwater to water garden flowers. When washing clothes, wait until the washing machine is full before starting it. Many people think fresh water is endless. But in some dry areas, local people are short of drinking water. Wasting water in daily life will increase pressure on our water resource system. Small good habits at home add up to big influence on natural environment. Everyone’s small action can make a real difference for water protection. ( )6. What percentage of earth’s surface is covered by water? A. About 30%. B. About 70%. C. About 50%. D. About 90%. ( )7. Which of the following is a good water‑saving habit? A. Collect rainwater to water flowers. B. Start washing‑machine with few clothes. C. Leave tap open when brushing teeth. D. Waste running water while washing hands. ( )8. What do people in some dry areas face? A. Too much rain every day. B. Shortage of drinking water. C. Lots of fresh river water. D. Plenty of underground water. ( )9. The underlined word “precious” in Paragraph1 means ____. A. 无用的 B. 廉价的 C. 普通的 D. 宝贵的 ( )10. What can we infer according to the text? A. Sea water can be drunk directly by human beings. B. Saving water at home has no influence on nature. C. Everyone’s small water‑saving actions are meaningful. D. Fresh water resources on the earth are endless. (三) Forests are the green lungs of our earth. Trees in forests take in carbon‑dioxide and produce fresh oxygen for us to breathe. Large forest areas can adjust local weather, slow down strong wind and hold back soil on hills. Without trees, heavy rain will wash away soil and cause landslides. Forests are also home for thousands of wild animals and plants. Different kinds of birds, small animals and plants live inside thick woods. If forests disappear, lots of living things will lose their living space and face the danger of dying out. However, human activities cause forest loss in some places. People cut down too many trees for farmland or wood products. To change this situation, more Chinese people take part in tree‑planting activities every year. Volunteers plant young trees on mountains and hills. Tree‑planting is not one‑day work. Young saplings need long‑time care. Protecting existing old forests is as important as planting new trees. ( )11. What do trees take in from air? A. Oxygen. B. Sunlight. C. Clean water. D. Carbon‑dioxide. ( )12. What may happen if there are no trees on hills when heavy rain comes? A. Soil will be washed away. B. Weather will become much colder. C. More animals will appear. D. Rain will stop falling at once. ( )13. What do volunteers do to protect forests? A. Cut down old big trees. B. Build houses inside forests. C. Plant young trees on mountains. D. Feed all wild forest animals. ( )14. The underlined word “saplings” in Paragraph 4 means ____. A. 树苗 B. 野花 C. 石头 D. 昆虫 ( )15. What is the main idea of the text? A. Different ways people use wood products. B. The importance of forests and forest protection. C. How wild animals look for food in thick woods. D. The history of ancient big forests in China. (四) Many people only think pollution means dirty water or dirty air. In fact, loud noise is also a kind of serious pollution. In modern cities, noise comes from many sources: busy traffic, building work, loud speakers and some public activities. Long‑time loud noise does harm to human health. It may hurt our hearing. It also makes people feel anxious and hard to fall asleep at night. Children living in noisy places may have trouble with their study and attention. Now cities make rules to control noise. Construction work must stop at night. Some roads set up noise‑stopping walls. Public places remind people to keep their voice down. Every citizen can also do small things. Do not turn up music too loud. Keep quiet in public areas. Noise pollution cannot be seen, but its influence is real. Good living environment needs us to pay attention to this invisible pollution. ( )16. What is noise pollution? A. Dirty river water. B. Loud harmful noise. C. Dirty smoke in air. D. Rubbish on streets. ( )17. Which is NOT the bad influence of long‑time loud noise? A. Hurt people’s hearing. B. Make people hard to sleep. C. Improve students’ memory quickly. D. Make people feel anxious. ( )18. What measure do cities take to control noise? A. Allow building work all night long. B. Encourage people to play loud music in streets. C. Set up noise‑stopping walls on some roads. D. Remove all public reminder signs. ( )19. The underlined word “invisible” in Paragraph4 means ____.

How to enjoy loud music every day. D. Why traffic must be very noisy. (五) Wild animal rescue stations take care of hurt or homeless wild animals. Some wild animals get hurt because of accidents or human influence. They cannot look for food or protect themselves in the wild. Workers in rescue stations give them medical care and enough food. Workers do not keep these animals forever. Their main goal is to help animals get back their wild living ability. They treat wounds, provide proper food and create wild‑like living environment for them. After animals get fully well and can survive in nature, workers will set them free back into the wild. Some people want to keep these wild animals as pets. But wild animals are not suitable for home raising. They belong to nature. If people keep wild animals at home, both humans and animals may face danger. Rescue work is meaningful but difficult. It teaches us that wild animals are not pets. Every wild creature has its own place in natural system. ( )21. What kind of animals do rescue stations take care of? A. Healthy pet dogs. B. Raised farm animals. C. House cats from families. D. Hurt or homeless wild animals. ( )22. What is the main purpose of the rescue station’s work? A. To keep wild animals inside buildings forever. B. To sell wild animals for money. C. To help animals return to wild nature. D. To let visitors play with wild animals. ( )23. Why shouldn’t we keep wild animals as pets at home? A. They eat too little food. B.

Rescue stations make big money from wild animals. 原创精品资源学科网独家享有版权，侵权必究！ 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $ 编写说明：【2027版】云南省（职教高考）《英语考纲百套卷》，依据最新版《中等职业学校公共基础课课程标准》、《云南省职教高考文化课程<英语>考试说明（暂定稿）》以及历年真题编写。本套试卷共100份：第一部分是40份考点训练卷。第二部分是45份题型专项训练卷。第三部分是15份不同难度等级的综合模拟卷。 本试卷是【2027版】云南省（职教高考）《英语考纲百套卷》的第58卷，是阅读理解（人与自然2） 题型专项训练卷。 【2027版】云南省（职教高考）《英语考纲百套卷》 第58卷 阅读理解（人与自然2） 考试时间：60分钟 满分：100分 班级 姓名 学号 成绩 阅读下面短文，从A、B、C、D四个选项中选出一个最佳选项。（本题共25小题，每小题4分，共100分） (一) Pandas are beloved national treasures of China.
