He is considered the greatest traveler and geographer in Chinese history. Xu was born in the Ming Dynasty. He took a strong interest in exploring China's rivers and mountains from an early age. To carry out his exploration, he spent many years travelling across China. He walked through many places and came across many troubles along the way, such as wild animals and freezing weather. Though the journey was very hard, he never stopped. He recorded his travel experiences in his diary.This later became Xu Xiake's Travel Notes. He also made geographical discoveries, like finding the true source of the Yangtze River. Finally, he had to end his last trip because he fell seriously ill. He made travel his life and had no regrets at all. His spirit of exploration and deep love of nature are truly inspiring. His story tells us that we should face challenges bravely and stick to our dreams. 学科网（北京）股份有限公司 $Unit five学情评估，一短对话理解，你将听到5段对话，每段对话后有一个小题请，在每小题所给的ABC3个选项中选出一个最佳选项，每段对话读两遍。Number one, Betty, do you like natural wonders of men made ones?

An ancient forest! This 32 discovery was found in Leye County, in Guangxi Zhuang Autonomous Region. People have 33 about 30 sinkholes there so far. How do sinkholes form? China has a karst landscape (喀斯特地貌), Veni told Live Science. Karst Landscapes are made when rainwater runs through little cracks (裂缝) in the 34 . The cracks slowly grow into tunnels (隧道) and then big caves (洞穴). Over time, a cave can get too 35 . Its ceiling then falls slowly, opening up huge sinkholes. Veni called China's sinkholes “ spectacular (壮观的)” because of 36 great sizes. Why are sinkholes important? Karst caves and sinkholes can be 37 to all kinds of plants, animals and microbes (微生物).“I wouldn't be surprised to know that some species (物种) in these caves have never been 38 or described by science until now,” said the leader of the exploration team, Chen Lixin. This is 39 sinkholes are separate from the outside world. Sinkholes also have deep stores of underground water. They are like nature's water pipes (管道).

A lot of mud and sand goes into the Yellow River in the season of heavy rainfall 42 the Loess Plateau is loose (松动的) and easy to wash away. The Yellow River originates (发源) from the Qinghai-Tibet Plateau and its 43 is similar to “几”．It runs from west to 44 through nine provinces and provincial-level administrative regions (省级行政区) runs into the Bohai Sea. The Yellow River was about 5,464 kilometers long, and the 45 it runs through covers about 752,443 km². In Chinese 46 ,the Yellow River was the most important birthplace.

F.I'm considering growing watermelons. G.Why not ask Mr. Green for a perfect space? 五.阅读理解 A The water cycle is very important for life on Earth. Let me tell you how it works. First, the sun shines on rivers, lakes and oceans. The heat makes water warm and go up into the air as very small drops. This is called evaporation. When these water drops go high into the sky, they get cold and come together to make clouds. This part is called condensation. Then, when the clouds become too heavy, the water falls back to the ground as rain or snow. We call this precipitation. The rainwater runs into rivers and lakes again, and some goes deep into the ground. Finally, the sun warms the water again, and the cycle starts over. This cycle gives us clean water to drink, so we must keep our rivers and oceans clean. 56.What makes water go up into the air? A.Wind B.Rain. C. Sunlight. D.Snow. 57.What is the correct order of the water cycle? a. Rain falls. b. The sun heats water. c.Clouds form. d. Water goes to rivers. A.b-c-a-d B.c-b-a-d C.a-d-b-c D.d-a-b-c 58.What's the main idea of the text? A.How to make rain. B.Why the sun is hot. C.How nature reuses water. D.Different kinds of clouds. B Lantern fish (灯笼鱼) are fish that carry their own lights. Most lantern fish are brown on top and silver underneath (在下面). They have very large eyes. They eat small sea animals. If you want to find them, you must go deep into the sea. As you go deeper and deeper, the daylight becomes dimmer and dimmer. At over152 meters below the surface of the water, the daylight is almost gone. The water is dark blue. There you will find lantern fish. There are over 230 different kinds of lantern fish in the world. Most lantern fish are just as long as your fingers. Even the biggest lantern fish are only about 15 centimeters (厘米) long. They are not large in size. However, each lantern fish has about 100 small round lights on the lower part of its body. The fish use their lights to help them catch food. They also use their lights to send information so that they can recognize each other. At night, they may swim up near the surface of the sea. Their lights shine like stars under the water. Lantern fish are one of the wonders of the sea. 59.What does the word "dimmer" mean in Paragraph 2? A.Quicker. B.Easier. C.Richer. D.Darker. 60.How many kinds of lantern fish are there in the world?

Do you know where it is? Many visitors love to refresh themselves in its natural beauty every year. Baiyun Mountain lies in southern Song County, Luoyang and belongs to the Funiu Mountain Ridge. It covers a total area of 168 square kilometers (about 64.9 square miles). There are 204 types of animals, 1,991 types of plants and 3,000 types of insects in the mountain. At 2,150 meters (about 7,054 feet) above sea level, White Cloud, the peak of Baiyun Mountain, is one of the main peaks of the Funiu Mountain Ridge. The clouds crowd around it, making it like a fairyland on earth. It's said that the peak can tell weather changes by the position of the clouds around the peak. The peak is a perfect place for mountain climbers to search for novelty. Little Huangshan Mountain is so named because it brings to mind the famous Mount Huangshan in Anhui Province, which is famous for its strange rocks. The beauty and strangeness of Little Huangshan Mountain are amazing. Different rock styles have been given interesting names such as Couple Stones and Bird's Nest Stone. The waterfalls are formed by the Baihe River which starts from Yuhuangding Peak. With enough water, it runs downwards and makes waterfalls and deep pools. The Jiulong Waterfall, Qinglong Waterfall, and the Heilong Pool are some of the pleasant sights in this area. 63.How does the writer start the passage? A.By asking questions. B.By listing numbers. C.By giving an example. D.By telling a story. 64.Which paragraphs describe (描述) the total area and peak? (①=Paragraph 1, ...) A.①② B.②③ C.③④ D.④⑤ 65.What does the last paragraph mainly talk about? A.The colourful peak. B.The different animals. C.The beautiful waterfalls. D.The wonderful Mount Huangshan. 66.Which is the right structure of the passage? (①=Paragraph 1, ...) A． B． C． D． D China's 13th scientific expedition (科学考察) to the Arctic Ocean reached the North Pole region (北极区域) 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 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. 67.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. 68.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 69.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. E Chinese scientists have made the world's first robot called GEAIR. It can finish all the steps of plant breeding (繁殖). This is very important for hybrid breeding. Hybrid breeding helps plants grow stronger and make more food. Yuan Longping made hybrid rice, and this rice has fed many Chinese people. According to Cell Press, the hybrid breeding process usually needs workers to take off the stamens (雄蕊) from the female plant first. Then they put pollen (花粉) from the male plant onto the female plant. This way, the new plants can get the best parts from both parent plants. For example, if you mix a male plant that doesn't get sick easily with a female plant that makes lots of fruit, you can get a new plant that has both of these good things. But hybrid breeding needs workers to do cross-pollination (异花授粉) over and over again in a short time. This work takes lots of time and energy. GEAIR fixes this problem. It uses AI visual recognition and positioning technology (定位技术) to walk between crops. When it finds flowers, it uses robotic arms to do cross-pollination and finish all the work. Making the robot was not easy. Leaves stand in the way, and flowers are very small. Traditional computer algorithms can't find them easily in real time. To solve this, the research team trained a new model with 12,800 flower pictures. With this model, GEAIR can pollinate each flower in 15 seconds. And the cost is much lower than a worker's yearly pay. 70.What is one purpose of hybrid breeding? A.To get more pollen. B.To create new plant types. C.To develop better plants. D.To mix female and male plants. 71.What does the underlined word “problem” in Paragraph 4 refer to? A.Human workers can easily hurt the flowers. B.Cross-pollination needs a lot of human work. C.Human workers cannot move freely among crops. D.Finding the flowers is difficult with leaves in the way. 72.What problem did scientists meet when making GEAIR? A.AI couldn't walk between crops. B.They had no pictures of flowers to use. C.Workers refused to help with the robot. D.Leaves got in the way and flowers were very small. F Shi Guangyin is a farmer and eco-warrior (生态战士) from Dingbian, Shaanxi Province. He grew up in a town near the Mu Us Desert. There,sandstorms often destroyed crops, houses, and even people's lives. Growing up in such an environment (环境) , Shi knows how much pain and harm the sand can cause. As a child, Shi experienced the pain of losing his home because of sandstorms. At the age of 8, he lost his best friend in a sandstorm. And these made him decide to fight against desertification (沙漠化) . Fighting against the desert is not easy. In 1968, Shi started leading local people to plant trees in the desert. After years of hard work, he found ways to grow trees in the sand. In 1984, he sold 84 sheep and borrowed money to plant trees on 200hectares (公顷) of land. Although he had many difficulties,including failures in the harsh (艰苦) area of Langwosha, Shi never stopped fighting. In 1988, he finally succeeded in greening Langwosha by using new planting technology. Shi was old. His son, Shi Zhanjun,continued planting trees but sadly died in a car accident while transporting trees. Shi's grandson then took up the responsibility. Together, they have turned 23, 334 hectares of desert into green land. Shi believes that fighting against desertification is his lifelong duty. He says,"I shall not stop planting trees until my last breath." His story shows how one person's will can make a big difference in protecting nature. 73.Why did Shi Guangyin decide to fight against desertification?
