(　)(新考法·篇章结构)What is the structure of this text?A. B. C. D.CIf you hit your head against a tree all day long, you probably wouldn't feel too great and neither would your brain. Woodpeckers do this all the time though.Some animals are humans' best friends. The woodpecker is one of them. It helps trees to grow by eating worms (虫子) inside the tree trunk. They find worms by hitting the tree 20 times a second! So why don't they get headaches?The answer is in their brains.A woodpecker's brain is different from a human's. Our brains are filled with cerebrospinal fluid (脑脊液). When we hurt our heads, our brains move around in the fluid. But woodpeckers have none of this fluid. This means that when they hit the tree, their brains are less likely to move around.Besides, thick muscles (肌肉) and sponge­like bones (海绵状骨头) also help to protect the birds when they're working on a tree trunk.The fast and strong hitting may also harm the woodpeckers' eyes. Don't worry. The birds have a special trick. They close their thick inner eyelids (内眼睑) when hitting the tree. The eyelid acts like a seat belt and keeps the eyes from popping out of the heads, or the speed would tear the eyes.Scientists even think some of the things they found out about woodpeckers can be used to make better helmets (头盔)．9. (　)(高阶思维·推理判断)What is the purpose of Paragraph 2?A．To tell a story. B．To raise a question.C．To give an example. D．To answer a question.10. (　)Which of the following can help woodpeckers protect their brains?①The texture (结构) of their brains.　②The cerebrospinal fluid.③Thick muscles.　④Sponge­like bones.　⑤Their inner eyelids.A．①③④ B．②③④ C．①③⑤ D．③④⑤11. (　)Why do woodpeckers close their inner eyelids when hitting trees?A．Because it can help them see clearly where worms are.B．Because it can help them keep their brains from moving around.C．Because it can help them get the male woodpeckers' attention.D．Because it can help them keep their eyes from popping out of the heads.12. (　)In which part of a newspaper can we read the passage?A．Sports. B．Health. C．Travel. D．Science.DChina's 13th scientific expedition (科学考察) to the Arctic Ocean reached the North Pole region (北极点区域) on September 5, 2023. You may wonder: What's the difference between doing research in the Arctic and Antarctica (南极) ? Research in the Arctic is more difficult than in Antarctica. Antarctica is mainly land. So scientists can set up research stations on the land. However, the Arctic is mainly an ocean. Scientists can only set up drifting stations or stations on boats in the Arctic. There are also other differences between the two poles. The Arctic is at the north end of Earth. Canada, Norway, Russia and five other countries have land there. Antarctica is at the south end of Earth. There are no countries there. People from all countries and regions can go there. They are both cold, but Antarctica is colder. The wind at the South Pole is very strong. It blows away the wind from warmer places. But the wind at the North Pole is not that strong. It mixes with the air from warmer places.13. (　)What information about the scientific expedition to the Arctic Ocean can we get from the first paragraph?A．September is the best time to go to the Arctic.B．China did 12 expeditions before 2023.C．13 scientists were in the North Pole region.D．The difference is being studied.14. (　)What does the underlined word “drifting” mean in Chinese?A．常温的 B．低温的 C．流动的 D．坚固的15. (　)How many countries have land in the Arctic?A．Five. B．Six. C．Seven. D．Eight.16. (　)Why is the Arctic warmer than Antarctica even though both of them are cold?A．The wind there isn't strong and mixes with warm air.B．People from all countries and regions can go there.C．The wind from warmer places is blown away.D．Many countries are along the North Pole region.第二节 阅读短文，从下面所给的选项中选出可以填入空白处的最佳选项，其中有一个多余的选项。More tigers are moving from Russia into northeastern China. 17. ______ As human activities become fewer and the number of the wild animals is rising, tigers come to China for food.Also, there is a cross­border corridor (跨境走廊) between China and Russia. 18. ______ Data (数据) from a research team show that between 2013 and 2016, nearly 80 percent of the tigers moved across the corridor.19. ______ As we all know, tigers need large areas to move around, so it's important to build national parks. In 2021, the Northeast China Tiger and Leopard National Park was set up in Heilongjiang Province and Jilin Province. It covers around 14，100 square kilometers. The national park creates a shared home for the animals.

We use plants for food, clothes and even the air we breathe. Plants keep our air and water clean. Green plants give us oxygen(氧气). Oxygen is part of the air we breathe.Plants are also part of the water cycle. Most of the water that a plant takes in goes back into the air. Plants give us a lot of food on the Earth. Fruits, vegetables and grains come from plants. Without plants, we would not have bread, rice, carrots, apples, oranges or bananas! Many people are growing plants to eat in their own gardens at home. Having your own garden helps the Earth as well.When you grow your own fruits and vegetables, you help cut down on pollution because big trucks don't need to take your food to shops. You also help reduce the amount of rubbish because you don't need to use bags for packing your food. You can just pick it out of the ground or off a plant and put it into a basket!Plants are quite important to humans and the Earth. Without plants, the Earth would be a very different place.41.

I like pine trees best.We can find pine trees everywhere. They stay green all year round. They are strong plants and we can grow them in many different environments. Pine trees take in carbon dioxide and use it to produce oxygen. They are useful to us in many ways. For example, we can use pine wood to make things, like tables and chairs.As for me, we should protect pine trees. First, we should stop cutting them down. Second, we can plant more pine trees to make our environment more beautiful and more comfortable. Let's work together to protect these wonderful trees.Thank you for listening!March 1，2025 SunnyToday our biology teacher gave everyone in our class some soybean seeds to plant.
