The desert is dry with much sand. But these trees are strong and they survive in hard conditions. People call them “Tokhrak” in Uyghur (维吾尔语), with the meaning of “beautiful tree”. The trees are old. Their bark (树皮) is thick, like a jacket. Their leaves are hard. When it rains, their roots go deep to find water and stay alive. They make a home for animals. Every autumn, leaves turn bright yellow. The color is like sunshine. The bright yellow leaves move in the wind. The forest attracts many people. Families come to walk and take photos. Under the trees, tourists can see “tiny snow” flying. They are tree seeds. Wind carries them. New trees grow from the seeds. These trees survive in the desert strongly, so people there call them “desert’s backbone (脊梁骨)”. The Tarim Poplar trees help the desert. Their roots hold soil. Wind can’t blow it away. Their wood is hard for building. People use their sap (汁) as food and medicine. Birds build their homes here. Sheep rest under trees. Weather here is changeable— hot or windy. But trees stand tall. They are a natural wonder. Bright yellow leaves show hope. They show life can grow in unusual places. Even in the desert, they stay alive and strong. 1．Where does the Tarim Poplar Forest grow? A．In a wet rainforest. B．Nearby a nice waterfall. C．By a dry desert.

The Northern Lights, also known as Aurora Borealis, are colorful lights in the sky near the North Pole. They usually appear at night, in colors like green, pink, and purple. Scientists say they are caused by solar winds hitting the Earth’s atmosphere. Another wonder is the Great Barrier Reef in Australia. It is the largest coral reef system in the world. Thousands of fish, turtles, and other sea animals live there. It’s so big that you can even see it from space! The Sahara Desert is the largest hot desert in the world. It covers most of North Africa. During the day, temperatures can reach 50°C, but at night it can get very cold. Even though it’s dry, some plants and animals can survive there, like cacti and camels. These natural wonders show us how powerful and beautiful nature is. We must protect them so people can enjoy them for years to come. 1．What is the main idea of the passage?

Ella replied happily that her trip was great and that she had visited the Hukou Waterfall on the Yellow River. Curiously, she asked Yaming if the Yellow River was the longest river in China. Yaming told her that it was not. He explained that the Yangtze River is the longest river in China, traveling the farthest with a length of about 6,300 kilometers. The Yellow River, which is 5,464 kilometers long, ranks second. Then Yaming asked Ella if she knew why it was called the Yellow River. Ella guessed it was because the river was yellow, and Yaming confirmed her answer, adding that some parts of the river carry brown and yellow earth. Ella thought it was interesting and said she liked learning about rivers. She mentioned that her favorite river is the Nile and asked Yaming if he knew it was the longest river in Africa. Yaming said yes, noting that the Nile is 6,671 kilometers long and has played a very important role in Egypt’s history. Ella agreed, pointing out that both the Nile and the Yellow River had helped ancient civilizations develop and that they were still very important today. Yaming added that in China, people even call the Yellow River their “mother river.” Finally, both of them agreed that they should do their best to protect these important rivers. 1．What did Ella do during her trip?

Let’s get closer to the Dead Sea and learn more about it. The Dead Sea is located in Southwest Asia. It is about 50 kilometers long and 15 kilometers wide at its widest point. It sits at about 430 meters below sea level, making it the lowest point on earth’s land. What’s interesting is that the Dead Sea isn’t actually a sea. It’s a lake. The salt concentration (盐浓度) in it is more than 30 percent, which is about eight times saltier than typical seawater. This makes it one of the saltiest bodies of water on earth. The Dead Sea stays so salty because of its special natural conditions. Each year, it receives very little rainfall, and only a small amount of freshwater flows into it. And the hot weather around the Dead Sea causes the freshwater to evaporate (蒸发) quickly, which makes the salt concentration even higher. For these reasons, it is also known as the Salt Sea. If you are to swim in the Dead Sea, you won’t see any sea life — no plants or animals. The high salt concentration makes it impossible for them to live there. That’s actually why it’s called the Dead Sea. However, don’t let the name or not having any sea life scare you. Even if you fall into the Dead Sea and can’t swim, you won’t die. The high concentration of salt in the Dead Sea allows anyone to float well, without the need for life buoys (救生圈) . In fact, many people visit the Dead Sea every year on vacation. If you walk along the lakeside, you’ll likely see many people floating in the water, reading books or magazines. 1．What do we know about the Dead Sea? A．It is the largest place in Asia. B．It is the widest sea in the world. C．It is the deepest point in America. D．It is the lowest lake on earth’s land. 2．What makes the Dead Sea so salty? A．A lot of seawater runs into it. B．Human activities improve the salt levels. C．Little rainfall and rapid evaporation of freshwater. D．The high temperature stops the water from freezing. 3．Why do people call it the Dead Sea? A．Because they cannot swim in it. B．Because it has something dangerous. C．Because it has the low salt concentration. D．Because no plants or animals can live in it. 4．What does the underlined word “float” probably mean? A．Sing in the room. B．Stay above water. C．Fly in the sky. D．Walk on the road. 5．What can we infer from the last paragraph? A．People feel scared when swimming in the Dead Sea. B．The Dead Sea is dangerous for people who can’t swim. C．If people can’t swim, they’ll still be safe in the Dead Sea. D．A life buoy is necessary when swimming in the Dead Sea. 【答案】1．D 2．C 3．D 4．B 5．C 【导语】本文是一篇说明文，主要介绍了死海的地理特征和独特之处。 1．细节理解题。根据第二段“It sits at about 430 meters below sea level … making it the lowest point on earth’s land”以及“It’s a lake with a salt concentration ... ”可知，死海是地球陆地最低点，且第三段明确提到它是“a lake”。故选D。 2．细节理解题。根据第四段“it receives very little rainfall ... fresh water evaporates quickly”可知，降水少、淡水蒸发快导致盐分浓缩。故选C。 3．细节理解题。根据第五段“The high salt concentration makes it impossible for them to live there. That’s actually why it’s called the Dead Sea”可知，高盐浓度使得动植物无法在那里生存。这就是为什么它被称为死海的原因。故选D。 4．词句猜测题。根据最后一段“without the need for life buoys”和“people floating in the water, reading books”可知，高盐度使人无需救生圈即可“漂浮”，即停在水面上。故选B。 5．推理判断题。根据最后一段“Even if you fall into the Dead Sea and can’t swim, you won’t die ... allows anyone to float well”可知，即使不会游泳，因浮力大仍安全。故选C。 进阶拓展训练5篇 The Hutuo River is the mother river of Shijiazhuang, the capital city of Hebei. The Hutuo River is famous for its rich history and cultural meaning. It has been important for transportation (交通) for centuries and has played an important part in the development of the area. The river has also been the subject of many poems and works of art in history. However, about 20 years ago, it was dirty and almost dried up. Thanks to the government’s work, it has become much cleaner. Wu Wenzhong, a 58-year-old villager, lives near the river. “My friends and I often played with water, swam and caught fish in it when I was a child. I liked catching fish best,” he said. He remembers that the villagers had to cross the river by boat at that time. But as time passed by, it got dirty and started to dry up. To remediate (治理) the river, the government has done a lot of things. They clean the river up and build levees (防洪堤). They plant trees, grass and flowers to green the riverside. They build up fences (防护栏) and put up “No Swimming” signs along the river to protect people. They stop factories from putting waste water into the river. They keep an eye on the river to make sure it stays clean for the fish, birds and people who live nearby. They also have a long-term plan to keep the river in good condition. Now, there are more than 20 kinds of birds living around the river. It becomes a home for birds again. People can enjoy a day outdoors with the beauty of nature along the river. Wu and other villagers are happy to see the river looking good again. The Hutuo River’s story shows that when people work together to take care of nature, good things can happen. 1．How does the writer introduce the subject in Paragraph 1? A．By giving examples. B．By giving facts. C．By asking questions. D．By quoting (引用) a famous poem. 2．What was Wu Wenzhong’s favourite activity when he was a child? A．Boating. B．Swimming. C．Planting trees. D．Catching fish. 3．What do we know about today’s Hutuo River? A．Many birds live around it. B．Factories get water from it. C．It’s still in bad condition. D．Villagers can have fun swimming in it. 4．What does “keep an eye on” mean in Paragraph 4? A．see off B．watch over C．find out D．look for 5．Which question does Paragraph 4 mainly answer? A．How does the river look now? B．When do people green the riverside? C．Why is the river important? D．What actions has the government taken? 【答案】1．B 2．D 3．A 4．B 5．D 【导语】本文是一篇说明文，介绍了滹沱河的历史、文化意义以及政府对其治理的成效。 1．推理判断题。通读第一段可知，此段介绍了滹沱河的历史、文化意义、交通作用等，由此可知作者通过列举事实引入主题。故选B。 2．细节理解题。根据文章第三段“I liked catching fish best”可知，Wu Wenzhong小时候最喜欢的活动是抓鱼。故选D。 3．细节理解题。根据文章第五段“Now, there are more than 20 kinds of birds living around the river.”可知，如今的滹沱河周围有许多鸟类栖息。故选A。 4．词句猜测题。根据文章第四段“They keep an eye on the river to make sure it stays clean for the fish, birds and people who live nearby.”可知，他们监视着这条河流，以确保它能保持清澈，从而为鱼儿、鸟类以及附近居民提供良好的生存环境，“keep an eye on”意为“监视、照看”，与“watch over”同义。故选B。 5．主旨大意题。根据文章第四段“To remediate the river, the government has done a lot of things...”可知，本段主要回答“政府采取了哪些行动治理河流”。故选D。 Qomolangma, at 8,848.86 meters, is the highest mountain in the world. Do you know how Qomolangma started to form? Qomolangma’s rocks once sat at the bottom of the ocean. Around 45 million years ago, the Indian plate (板块) moved and hit the Eurasian plate. It made the land rise up and Qomolangma formed. Do you know that Qomolangma keeps growing? According to a new study by scientists from University College London (UCL), Qomolangma grew by 15 to 50 meters because of a geographic event about 89,000 years ago. However, the UCL team found that Qomolangma is growing faster these years. They estimated (估计) this to be between 0.16 and 0.53 millimeters each year! Now the height of Qomolangma rises a little bit every year because of big forces (力量) under the ground. It is also affected by weather conditions such as ice and snow. And rivers also affect it. The Arun River, which runs close to Qomolangma, has been cutting through rocks and washing away the land over time. This makes the mountain lighter, allowing it to rise like a boat when weight is taken away. The process of this rising is isostatic rebound (地壳均衡回弹). This means the Earth’s surface moves up or down when something heavy is taken away or put on. Qomolangma is not the only mountain that changes. The UCL team said that nearby mountains, Lhotse and Makalu, the fourth and fifth highest in the world, are also growing a little bit each year. How amazing nature is! 1．How does the writer start the passage? A．By showing a fact. B．By telling a story. C．By asking a question D．By listing numbers. 2．What is Paragraph 1 mainly about? A．How high Qomolangma is. B．Where Qomolangma is. C．How Qomolangma formed. D．How old Qomolangma is. 3．What is the structure of the passage? A． B． C． D． 4．What would be the best title for the passage? A．Climbing to the top B．Qomolangma is getting taller C．Research on Mount Qomolangma D．Go and visit Mount Qomolangma 【答案】1．A 2．C 3．B 4．B 【导语】本文是一篇说明文，介绍了珠穆朗玛峰的形成原因、高度变化以及它并非唯一仍在增长的山峰，展现了自然的神奇之处。 1．推理判断题。根据文章开头以“Qomolangma, at 8,848.86 meters, is the highest mountain in the world.”可知，开篇直接陈述事实，引出下文，因此作者是通过展示事实来开篇的。故选A。 2．主旨大意题。根据“Qomolangma, at 8,848.86 meters, is the highest mountain in the world.  … Around 45 million years ago, the Indian plate (板块) moved and hit the Eurasian plate. It made the land rise up and Qomolangma formed.”可知，第一段介绍了珠穆朗玛峰的高度，并说明了它是由板块运动形成的，核心是解释珠穆朗玛峰是如何形成的。故选C。 3．篇章结构题。根据“Qomolangma, at 8,848.86 meters, is the highest mountain in the world.”，“Qomolangma grew by 15 to 50 meters because of a geographic event about 89,000 years ago … This makes the mountain lighter, allowing it to rise like a boat when weight is taken away.”，“The UCL team said that nearby mountains”可知，第①段总起，介绍珠穆朗玛峰的基本信息与形成原因；第②-③段分述，分别介绍珠穆朗玛峰的高度增长数据、增长原因；第④段总结，指出珠穆朗玛峰并非唯一仍在增长的山峰。因此文章结构为“总—分—总”。故选B。 4．最佳标题题。根据“However, the UCL team found that Qomolangma is growing faster these years. They estimated (估计) this to be between 0.16 and 0.53 millimeters each year!”，“The UCL team said that nearby mountains … ”可知，全文围绕“珠穆朗玛峰仍在变高”展开，介绍了它的增长原因、数据，以及其他山峰的增长情况。因此最佳标题是Qomolangma is getting taller。故选B。 时文原创 Mount Qomolangma, at 8,848.86 meters, is the highest mountain in the world. It’s one of the greatest natural wonders that many climbers want to explore. Do you know how Mount Qomolangma started to form?Mount Qomolangma’s rocks once sat at the bottom of the ocean. Around 45 million years ago, the Indian plate (板块) moved and hit the Eurasian plate. It made the land rise up and Mount Qomolangma formed. Do you know that Mount Qomolangma keeps growing?According to a new study by scientists from University College London (UCL) Qomolangma grew by 15 to 50 meters because of a geographic event about 89,000 years ago. However, the UCL team found that Mount Qomolangma is growing faster these years. They estimated (估计) this to be between 0.16 and 0.53 millimeters each year! Now the height of Mount Qomolangma rises a little bit every year because of big forces (力量) under the ground. It is also affected by weather conditions such as ice and snow. And rivers also affect it. The Arun River, which runs close to Mount Qomolangma, has been cutting through rocks and washing away the land over time. This makes the mountain lighter, allowing it to rise like a boat when weight is taken away. The process of this rising is isostatic rebound (地壳均衡回弹). This means the earth’s surface moves up or down when something heavy is taken away or put on. Mount Qomolangma is not the only mountain that changes. The UCL team said that nearby mountains, Lhotse and Makalu, the fourth and fifth highest in the world, are also growing a little bit each year.

What about Mount Denali (德纳里山) in America? Denali in Denali National Park in Alaska is the highest peak in North America. It is about 20, 308 feet above sea level. Denali is one of the most d… mountains in the Western Hemisphere for mountain climbers. Denali is closer to the North Pole (北极) than other tall mountains. This means that the air is thinner, so it’s harder for climbers. The first group of climbers got to the top of Denali in 1913. Two other groups were successful after that. The next group got to the top in 1947. This group had a husband and a wife, Bradford and Barbara Washburn. Barbara was the first woman to successfully climb the mountain. The Washburns were not climbing for sport; they were explorers. In the field of mountain mapping, Bradford Washburn was one of the best. The Washburns mapped many mountains and the Grand Canyon. Bradford dreamed of mapping Mount Qomolangma. Later they produced the best map ever made of Mount Qomolangma. 1．Where is Mount Denali? A．In Asia. B．In America. C．In Europe.

The Big Stone River is the most interesting sight (景象) of Taganay National Park in Russia. Different from other rivers, it is filled with rocks and stones. Not a drop of water can be seen. Interestingly, as one comes near to the rocky river, the sound of running water can be heard. Rocks fell down from the mountains slowly and made the river of rocks. The Big Stone River is about 6 km long and is made up of many small rocky rivers. It cuts through a thick forest like a real river. It is about 200 metres wide and in some places, it is up to 700 metres wide. Some of the rocks weigh up to 10 tons each and the layer (层) of rocks goes down 6 metres deep. Scientists believe it is the consequence of the movement of glaciers (冰川) about 10, 000 years ago. At that time, ice covered the top of the mountains. As time went by, the ice turned into water. Seeing the amazing river is a great experience. The best way to experience this natural wonder is from above. Come and visit it when you come to Russia. 1．Why is the Big Stone River special? A．Because it is in Taganay National Park. B．Because it is full of fish. C．Because it is impossible to see water there.

After spending hours indoors, do you feel better when you visit your local park? I believe the answer must be “YES”. Most people think that nature is good for our bodies and brains. However, humans are spending more time inside and less time outside. For example, the number of visitors to Canada’s national parks is getting smaller every year. And in countries such as the USA, only 10% of teenagers spend time outside every day. Many doctors feel that this is a problem in the twenty-first century. Therefore, some doctors are studying the connection between nature and health: one example is the work of Dr. Matilda in Sweden. The doctor gave people a maths test. During the test, their heart rates(心率) were fast. After the test, one group of people sat in a 3D-virtual-reality(虚拟现实) room for fifteen minutes with pictures and sounds of nature. Their heart rates were slower than people’s in the other group. The virtual touch with nature helped them feel more relaxed. The natural world allows our brains to rest and slow down, and can leave us feeling happier and less stressed. Another example from Canada also shows nature is good for health. In Toronto, researchers studied 31,000 people living in the city. In general, they found that healthier people lived near parks. Because of studies like these, some countries and cities want people to enjoy nature in their everyday life. In Dubai, people plan to build a new shopping mall with a large garden, so shoppers can relax outside with trees, plants and water. And South Korea has new forests near its cities and around 13 million people visit these forests every year. Getting close to nature has been thought to be necessary for brain development in children. In Switzerland, “forest schools” are popular. School children study their subjects in the forests and exercise a lot outside. So after building cities for so long, perhaps it’s now time to start rebuilding nature. 1．What does the underlined word “this” in paragraph 2 refer to? A．People spend more time inside than outside. B．People think nature is good for our bodies. C．Only teenagers spend time outside every day. D．The number of people to parks changes every day. 2．After the maths test, which of the following helped slow the heart rates of people? A．The advice from the doctor. B．Pictures and sounds of nature. C．The maths problems in the test. D．The real natural world. 3．What do the results of the studies show in paragraph 3? A．The maths test is bad for health as it makes people nervous. B．People’s heart rates get slower in a 3D-virtual-reality room. C．More and more Canadians will move to live near parks. D．Nature can help people be more relaxed and healthier. 4．To help people enjoy nature, which of the following is not done by the countries? A．Building new forests near cities. B．Inventing a brain development programme. C．Planning a green area for shoppers. D．Having classes and doing sports in the forest. 5．What can we learn from the last sentence of the passage? A．Nature is more important than cities. B．Country life is healthier than city life. C．Nature should be part of people’s life. D．People have lived in cities for so long. 【答案】1．A 2．B 3．D 4．B 5．C 【导语】本文是一篇说明文，文章介绍了自然对人类的影响，亲近自然环境能让人更放松，呼吁大家让自然成为我们日常生活的一部分。 1．词义猜测题。根据“humans are spending more time inside and less time outside”及“a problem”人们在室内比在室外的时间更多，很多医生认为这是一个问题，可知“this”指的是人们在室内比在室外更多。故选A。 2．细节理解题。根据“After the test, one group of people sat in a 3D-virtual-reality(虚拟现实) room for fifteen minutes with pictures and sounds of nature. Their heart rates were slower than people’s in the other group.”可知，一组人在有自然的图片和声音的教室里坐了15分钟，里面他们的心率比另一组的人慢。所以是自然的图片和声音帮助他们减缓心率速度，故选B。 3．细节理解题。根据“Their heart rates were slower than people’s in the other group. The virtual touch with nature helped them feel more relaxed.”以及”Another example from Canada also shows nature is good for health.“可知，与大自然的接触帮助人们感到更加放松和健康。故选D。 4．推理判断题。根据“In Dubai, people plan to build a new shopping mall with a large garden, so shoppers can relax outside with trees, plants and water. And South Korea has new forests near its cities and around 13 million people visit these forests every year. Getting close to nature has been thought to be necessary for brain development in children. In Switzerland,‘forest schools’are popular. School children study their subjects in the forests and exercise a lot outside”可知，为了帮助人们享受自然，有些国家为购物者规划一个绿色区域，有些国家在城市附近构建自然环境，有些国家开设“森林学校”让学生在大自然中上课和运动，可知A、C、D选项文中都有提到。B选项“发明一个大脑发育项目”文章中没有提到。故选B。 5．推理判断题。根据“So after building cities for so long, perhaps it’s now time to start rebuilding nature.”可知，在建设了这么长时间的城市之后，也许现在是时候开始重建自然了，故推断作者在此呼吁大家让自然成为我们日常生活的一部分。故选C。 Did you ever dream of traveling all the way over the rainbow (彩虹)? In fact, it’s easier than you think. All you need to do is to buy a plane ticket to Peru (秘鲁). The South American country is home to wonderful natural sights, and one of the most amazing is Rainbow Mountain. Rainbow Mountain, also called Mountain of Seven Colors, lies in the Andes in Cusco. As its name shows, the mountain has different colors. It attracts (吸引) lots of tourists every year. But what makes the mountain look like it is painted in yellows, greens, reds, and purples? The reason is the ice that covered the area centuries ago. When it began to melt, the water mixed with minerals (矿物质) in the ground, turning the earth into the many colors you see today. If you plan your trip to the mountain, you’d better visit it during warmer months when there will be less rain or snow. Rain or snow will make the climbing more difficult and the colors will look duller (更暗淡的). The best time begins in March and lasts nine months, when there will be blue skies and pleasant weather. At the same time, visit it in the morning or during evening hours, either right after sunrise or right before sunset. Very sunny days may prevent you from taking nice photos. To get to Rainbow Mountain, you should first go to Cusco. From the city, you can take a two-or-three-hour car ride to Pitumarca. Then you have to make your way to Qesoyuno to start the journey on foot. Once you arrive at the base (大本营), it’s about a two-or-three-hour walk to the top. This really is the best way, but the trip is very challenging. The other important thing to remember is that the mountain sits at a really high elevation (纬度) about 5,200 meters above sea level, so prepare enough water and take your time. 1．How does the writer start the passage? A．By listing a fact. B．By telling a story. C．By asking a question. D．By giving an example. 2．What does the underlined word “melt” mean in Chinese? A．融化 B．熔化 C．蒸发 D．凝固 3．Which of the following is a perfect time for a trip to Rainbow Mountain? A．At noon of a cold day in December. B．On the evening of a rainy day in August. C．On the afternoon of a snowy day in January. D．On the morning of a sunny day in September. 【答案】1．C 2．A 3．D 【导语】本文是一篇说明文。文章主要介绍了秘鲁的彩虹山。 1．细节理解题。根据第一段“Did you ever dream of traveling all the way over the rainbow (彩虹)?”可知，在文章开头，作者先问了一个问题。故选C。 2．词义猜测题。根据第三段“The reason is the ice that covered the area centuries ago. When it began to melt, the water mixed with minerals (矿物质) in the ground, turning the earth into the many colors you see today.”可知，冰融化而成的水与地下的矿物质混合在一起，形成了你今天看到的许多颜色；据此可以推断，划线单词“melt”是指冰块变成水的过程，即“融化”。故选A。 3．推理判断题。根据“If you plan your trip to the mountain, you’d better visit it during warmer months when there will be less rain or snow. Rain or snow will make the climbing more difficult and the colors will look duller (更暗淡的).”可知，应当在雨雪少的时候去，排除B和C；根据“The best time begins in March and lasts nine months, when there will be blue skies and pleasant weather.”可知，最佳月份是从三月份开始的9个月，也就是三月到十一月，排除A选项；再根据“At the same time, visit it in the morning or during evening hours, either right after sunrise or right before sunset.”可知，一个九月阳光明媚的早晨是去彩虹山旅行的最佳时间。故选D。 Where can you see auroras (极光)? Iceland? The North Pole? Actually, early this December, sky lovers in cities as south as Beijing could see them, too. They enjoyed the colored lights in the night sky. Auroras come about because of the special activities of the Sun. The Sun sends out very small particles (粒子) all the time. But sometimes, it becomes more active and lets out more. The particles travel in space like a wind. When they come near Earth, they go around it. This is because the magnetic field (磁场) of Earth “protects” us from the “Wind”. At the North and South Poles, however, some particles may get in and meet with Earth’s air. Then, the particles get “excited” and have a “dance” with the air. So, we can see the moving auroras in the sky. When the “wind” is strong enough, the auroras can cover larger areas. While we feel wowed by the beautiful lights, we often ask, “Do auroras hurt us?” The answer is no. Auroras don’t hurt people’s health. But for astronauts (宇航员) in space, they need to use special ways to protect themselves from them, said Xinhua. For example, they won’t go on spacewalks when there are “sun storms”. Also, the particle storms may stop some satellites (卫星) from working, so they may bring trouble to the GPS on our smartphones. 1．Where are small particles from? A．The Sun. B．The North Pole. C．The South Pole. D．Seas. 2．How do auroras form? A．The Sun sends out active particles. B．Particles from the Sun “dance” with the air on Earth. C．The strong wind helps them travel in space. D．The magnetic field of Earth changed small particles. 3．What can we learn about “sun storms” from the last paragraph? A．“Sun storms” will kill astronauts. B．People can enjoy “sun storms” in the night sky. C．“Sun storms” can stop GPS work well. D．“Sun storms” will cause more sun activities. 4．Where can we probably read this passage? A．In a storybook. B．In a science book. C．In a diary. D．In a comic book. 【答案】1．A 2．B 3．C 4．B 【导语】本文主要介绍了一些关于极光的科普知识。 1．细节理解题。根据“The Sun sends out very small particles (粒子) all the time.”可知小粒子来自太阳。故选A。 2．细节理解题。根据“At the North and South Poles, however, some particles may get in and meet with Earth’s air. Then, the particles get ‘excited’ and have a ‘dance’ with the air. So, we can see the moving auroras in the sky.”可知极光产生于来自太阳的粒子与地球上的空气“共舞”。故选B。 3．细节理解题。根据“Also, the particle storms may stop some satellites (卫星) from working, so they may bring trouble to the GPS on our smartphones.”可知“太阳风暴”可以阻止GPS正常工作。故选C。 4．推理判断题。本文主要介绍了一些关于极光的科普知识，由此推出可能在科学书上读到。故选B。 When we look at the Earth, we see many different things. Sometimes, you may hear people talk about landform and landscape. Are they the same thing? Let’s find out! A landform is a natural feature of the Earth’s surface. Think of big mountains that rise high up, low valleys (山谷) between hills, flat plains that go on and on, and sandy deserts. These are all landforms. They are made by nature over a long, long time. For example, mountains are formed when huge pieces of the Earth’s surface push against (撞) each other. Valleys can be made by rivers cutting through the land little by little. Each landform has a name that tells us what it looks like and how it was formed. Scientists study landforms to learn about the history of the Earth. A landscape, on the other hand, is what you see when you look at an area of land. It includes (包括) landforms, but it also has other things like plants, buildings, and lakes. Imagine standing on top of a hill. You can see green trees waving in the wind, a small village with houses, and a clear lake nearby. All these things together make up the landscape. A landscape can change rapidly. If people build new buildings or cut down a lot of trees, the landscape will look different in just a few months. Let’s take a forest in the mountains as an example. The mountain is the landform — it’s a natural feature of the Earth. But when you see the tall trees, hear the birds singing, and watch a little stream (溪流) running down the mountain, that’s the landscape. So, the key difference is this: landform is about the natural shapes of the Earth, and landscape is about the whole view of an area, including both natural and man-made things. Next time you go on a trip, try to enjoy different landforms and describe (描述) the beautiful landscapes around you! 1．Which of the following is a landform? A．A newly-built bridge. B．A flat plain. C．A group of trees. D．A small house. 2．What can we learn from the text about how mountains are formed? A．They are made by people building up the land. B．They are formed when rivers cut through the land. C．They are formed when the Earth’s plates push into each other. D．They are formed by heavy rain and strong winds. 3．What does the underlined word “rapidly” in Paragraph 3 probably mean? A．Brightly. B．Quickly. C．Powerfully. D．Quietly. 4．What does “landscape” usually include? A．Only landforms. B．Only natural things. C．Just man-made things. D．Landforms, trees, houses and lakes. 5．How does the writer explain the difference between landform and landscape? A．By telling stories. B．By listing numbers. C．By giving examples. D．By asking questions. 【答案】1．B 2．C 3．B 4．D 5．C 【导语】本文是一篇说明文，介绍了地形和景观的区别。 1．细节理解题。根据“Think of big mountains that rise high up, low valleys (山谷) between hills, flat plains that go on and on, and sandy deserts. These are all landforms.”可知，高耸的大山、小山之间的低山谷，连绵不断的平原，还有沙漠，这些都是地形。故选B。 2．细节理解题。根据“mountains are formed when huge pieces of the Earth’s surface push against (撞) each other”可知，山是由地球表面的巨大板块相互推动而形成的。故选C。 3．词义猜测题。根据“If people build new buildings or cut down a lot of trees, the landscape will look different in just a few months.”可知，如果人们建造新的建筑物或砍伐大量的树木，景观将在短短几个月内看起来不同。因此景观的变化很快，rapidly和quickly都表示“快的，迅速的”。故选B。 4．细节理解题。根据“It includes (包括) landforms, but it also has other things like plants, buildings, and lakes.”可知，景观包括地形，但也有其他东西，如植物、建筑物和湖泊。故选D。 5．推理判断题。通读全文，结合文中关键词句“For example”“Let’s take a forest in the mountains as an example.”等可知，作者通过列举很多的事物来解释什么是地形和景观。故选C。 Rainforests (热带雨林) are some of the most amazing places on Earth. They cover only about 6% of the world’s land, but are home to more than half of all living things. These dense forests are full of life, from tiny insects to large animals, and from small plants to tall trees. The rainforest has different layers. The top layer is called the emergent layer, where the tallest trees reach up to 70 meters. Below that is the canopy, a thick layer of leaves and branches that stops most sunlight from reaching the layers below. Next is the understory, with smaller trees and bushes. The bottom layer is the forest floor, where only a little sunlight gets through. Many rainforest animals have special skills to live in their layers. For example, sloths hang from the canopy branches. Their long claws help them stay there, and their slow movement helps them save energy. Toucans have big beaks to reach fruit on thin branches that can’t hold their weight. On the forest floor, jaguars use their spots to hide in the shadows while hunting. Rainforests are important for the whole world. They take in carbon dioxide (二氧化碳) and give out oxygen (氧气), which helps keep the air clean. They also help control the world’s weather. But rainforests are in danger. Every year, large areas are cut down for wood or to make space for farms. This destroys the homes of many animals and plants, and may even change the world’s climate. 1．What percentage of the world’s land do rainforests cover? A．About 6%. B．About 16%. C．About 26%. D．About 36%. 2．What does the word “dense” mean in the first paragraph? A．Dry. B．Thick with plants. C．Cold. D．Easy to walk through. 3．Why do toucans have big beaks? A．To hang from branches. B．To hide from predators. C．To reach fruit on thin branches. D．To run fast on the forest floor. 4．Put the layers of the rainforest from top to bottom. ①understory ②emergent layer ③forest floor ④canopy A．②→④→①→③ B．④→②→①→③ C．②→①→④→③ D．④→①→②→③ 5．What is the main idea of the passage? A．How animals live in the rainforest. B．The layers of the rainforest. C．Why rainforests are amazing and important. D．How to cut down rainforests. 【答案】1．A 2．B 3．C 4．A 5．C 【导语】本文介绍了热带雨林的相关情况，包括其覆盖面积、分层结构、生活在其中的动物的特殊生存技能，以及热带雨林的重要性和面临的危险。 1．细节理解题。根据第一段“They cover only about 6% of the world’s land”可知，热带雨林约覆盖世界陆地的大约6%。故选A。 2．词义猜测题。根据第一段“from tiny insects to large animals, and from small plants to tall trees”可知，热带雨林中生活着从微小昆虫到大型动物、从小植物到高大树木等众多生物，由此可推测“dense”意为“植物茂密的”。故选B。 3．细节理解题。根据第三段“Toucans have big beaks to reach fruit on thin branches that can’t hold their weight” 可知，巨嘴鸟有大喙是为了够到细树枝上的果实。故选C。 4．细节理解题。根据第二段“The top layer is called the emergent layer... Below that is the canopy... Next is the understory... The bottom layer is the forest floor”可知，顺序是emergent layer→canopy→understory→forest floor，即②→④→①→③。故选A。 5．主旨大意题。文章介绍了热带雨林的奇妙之处，并说明了它对世界的重要性及其面临的危机。全文的核心是阐述热带雨林为何既神奇又重要。故选C。 2 同步新教材，周周有练习，月月有重点！ 1 同步新教材，周周有练习，月月有重点！ 学科网（北京）股份有限公司 $ 2025-2026学年一线教师制作新教材英语同步精品系列资料，名师遴选！ 2025-2026学年一线教师制作新教材英语同步精品系列资料，名师遴选！ 学校:___________姓名：___________班级：___________考号：___________ Unit 4 The Wonders of Nature 单元话题（自然奇观）阅读理解进阶练15篇 说明：此专题分三个难度层次，基础入门训练<进阶拓展训练< 能力综合实践，老师根据学生实际情况进行针对性难度训练。 基础入门训练5篇 The Great Blue HoleA famous underwater cave in Belize. —Dive to see colorful corals and sea creatures. —Guided tours available every morning.

C．You can climb all of them. D．They are in the same country. In western China, there is the Tarim Poplar Forest (塔里木胡杨林) growing by the Taklamakan Desert. The desert is dry with much sand. But these trees are strong and they survive in hard conditions. People call them “Tokhrak” in Uyghur (维吾尔语), with the meaning of “beautiful tree”. The trees are old. Their bark (树皮) is thick, like a jacket. Their leaves are hard. When it rains, their roots go deep to find water and stay alive. They make a home for animals. Every autumn, leaves turn bright yellow. The color is like sunshine. The bright yellow leaves move in the wind. The forest attracts many people. Families come to walk and take photos. Under the trees, tourists can see “tiny snow” flying. They are tree seeds. Wind carries them. New trees grow from the seeds. These trees survive in the desert strongly, so people there call them “desert’s backbone (脊梁骨)”. The Tarim Poplar trees help the desert. Their roots hold soil. Wind can’t blow it away. Their wood is hard for building. People use their sap (汁) as food and medicine. Birds build their homes here. Sheep rest under trees. Weather here is changeable— hot or windy. But trees stand tall. They are a natural wonder. Bright yellow leaves show hope. They show life can grow in unusual places. Even in the desert, they stay alive and strong. 1．Where does the Tarim Poplar Forest grow? A．In a wet rainforest. B．Nearby a nice waterfall. C．By a dry desert.

D．Because they attract many tourists. 5．What does Paragraph 4 mainly talk about? A．Why the Tarim Poplar trees help the desert. B．How the Tarim Poplar trees help the desert. C．When the Tarim Poplar trees help the desert. D．Whether the Tarim Poplar trees help the desert. Natural wonders are amazing sights created by nature. Let’s look at some of them. The Northern Lights, also known as Aurora Borealis, are colorful lights in the sky near the North Pole. They usually appear at night, in colors like green, pink, and purple. Scientists say they are caused by solar winds hitting the Earth’s atmosphere. Another wonder is the Great Barrier Reef in Australia. It is the largest coral reef system in the world. Thousands of fish, turtles, and other sea animals live there. It’s so big that you can even see it from space! The Sahara Desert is the largest hot desert in the world. It covers most of North Africa. During the day, temperatures can reach 50°C, but at night it can get very cold. Even though it’s dry, some plants and animals can survive there, like cacti and camels. These natural wonders show us how powerful and beautiful nature is. We must protect them so people can enjoy them for years to come. 1．What is the main idea of the passage?

Ella replied happily that her trip was great and that she had visited the Hukou Waterfall on the Yellow River. Curiously, she asked Yaming if the Yellow River was the longest river in China. Yaming told her that it was not. He explained that the Yangtze River is the longest river in China, traveling the farthest with a length of about 6,300 kilometers. The Yellow River, which is 5,464 kilometers long, ranks second. Then Yaming asked Ella if she knew why it was called the Yellow River. Ella guessed it was because the river was yellow, and Yaming confirmed her answer, adding that some parts of the river carry brown and yellow earth. Ella thought it was interesting and said she liked learning about rivers. She mentioned that her favorite river is the Nile and asked Yaming if he knew it was the longest river in Africa. Yaming said yes, noting that the Nile is 6,671 kilometers long and has played a very important role in Egypt’s history. Ella agreed, pointing out that both the Nile and the Yellow River had helped ancient civilizations develop and that they were still very important today. Yaming added that in China, people even call the Yellow River their “mother river.” Finally, both of them agreed that they should do their best to protect these important rivers. 1．What did Ella do during her trip? A．She visited the Yangtze River. B．She saw the Hukou Waterfall on the Yellow River. C．She traveled to Egypt to see the Nile. D．She learned about China’s ancient civilizations. 2．Which of the following is the longest river in China? A．The Yellow River. B．The Nile. C．The Yangtze River. D．We don’t know from the passage. 3．Why is the Yellow River called “the mother river” in China? A．Because it is the longest river in China. B．Because it carries brown and yellow earth. C．Because it helped ancient Chinese civilization develop and is still important today. D．Because it is Ella’s favorite river. 4．How long is the Nile? A．About 6,300 kilometers. B．5,464 kilometers.

Let’s get closer to the Dead Sea and learn more about it. The Dead Sea is located in Southwest Asia. It is about 50 kilometers long and 15 kilometers wide at its widest point. It sits at about 430 meters below sea level, making it the lowest point on earth’s land. What’s interesting is that the Dead Sea isn’t actually a sea. It’s a lake. The salt concentration (盐浓度) in it is more than 30 percent, which is about eight times saltier than typical seawater. This makes it one of the saltiest bodies of water on earth. The Dead Sea stays so salty because of its special natural conditions. Each year, it receives very little rainfall, and only a small amount of freshwater flows into it. And the hot weather around the Dead Sea causes the freshwater to evaporate (蒸发) quickly, which makes the salt concentration even higher. For these reasons, it is also known as the Salt Sea. If you are to swim in the Dead Sea, you won’t see any sea life — no plants or animals. The high salt concentration makes it impossible for them to live there. That’s actually why it’s called the Dead Sea. However, don’t let the name or not having any sea life scare you. Even if you fall into the Dead Sea and can’t swim, you won’t die. The high concentration of salt in the Dead Sea allows anyone to float well, without the need for life buoys (救生圈) . In fact, many people visit the Dead Sea every year on vacation. If you walk along the lakeside, you’ll likely see many people floating in the water, reading books or magazines. 1．What do we know about the Dead Sea? A．It is the largest place in Asia. B．It is the widest sea in the world. C．It is the deepest point in America. D．It is the lowest lake on earth’s land. 2．What makes the Dead Sea so salty? A．A lot of seawater runs into it. B．Human activities improve the salt levels. C．Little rainfall and rapid evaporation of freshwater. D．The high temperature stops the water from freezing. 3．Why do people call it the Dead Sea? A．Because they cannot swim in it. B．Because it has something dangerous. C．Because it has the low salt concentration. D．Because no plants or animals can live in it. 4．What does the underlined word “float” probably mean? A．Sing in the room. B．Stay above water. C．Fly in the sky. D．Walk on the road. 5．What can we infer from the last paragraph? A．People feel scared when swimming in the Dead Sea. B．The Dead Sea is dangerous for people who can’t swim. C．If people can’t swim, they’ll still be safe in the Dead Sea. D．A life buoy is necessary when swimming in the Dead Sea. 进阶拓展训练5篇 The Hutuo River is the mother river of Shijiazhuang, the capital city of Hebei. The Hutuo River is famous for its rich history and cultural meaning. It has been important for transportation (交通) for centuries and has played an important part in the development of the area. The river has also been the subject of many poems and works of art in history. However, about 20 years ago, it was dirty and almost dried up. Thanks to the government’s work, it has become much cleaner. Wu Wenzhong, a 58-year-old villager, lives near the river. “My friends and I often played with water, swam and caught fish in it when I was a child. I liked catching fish best,” he said. He remembers that the villagers had to cross the river by boat at that time. But as time passed by, it got dirty and started to dry up. To remediate (治理) the river, the government has done a lot of things. They clean the river up and build levees (防洪堤). They plant trees, grass and flowers to green the riverside. They build up fences (防护栏) and put up “No Swimming” signs along the river to protect people. They stop factories from putting waste water into the river. They keep an eye on the river to make sure it stays clean for the fish, birds and people who live nearby. They also have a long-term plan to keep the river in good condition. Now, there are more than 20 kinds of birds living around the river. It becomes a home for birds again. People can enjoy a day outdoors with the beauty of nature along the river. Wu and other villagers are happy to see the river looking good again. The Hutuo River’s story shows that when people work together to take care of nature, good things can happen. 1．How does the writer introduce the subject in Paragraph 1? A．By giving examples. B．By giving facts. C．By asking questions. D．By quoting (引用) a famous poem. 2．What was Wu Wenzhong’s favourite activity when he was a child? A．Boating. B．Swimming. C．Planting trees. D．Catching fish. 3．What do we know about today’s Hutuo River? A．Many birds live around it. B．Factories get water from it. C．It’s still in bad condition. D．Villagers can have fun swimming in it. 4．What does “keep an eye on” mean in Paragraph 4? A．see off B．watch over C．find out D．look for 5．Which question does Paragraph 4 mainly answer? A．How does the river look now? B．When do people green the riverside? C．Why is the river important? D．What actions has the government taken? Qomolangma, at 8,848.86 meters, is the highest mountain in the world. Do you know how Qomolangma started to form? Qomolangma’s rocks once sat at the bottom of the ocean. Around 45 million years ago, the Indian plate (板块) moved and hit the Eurasian plate. It made the land rise up and Qomolangma formed. Do you know that Qomolangma keeps growing? According to a new study by scientists from University College London (UCL), Qomolangma grew by 15 to 50 meters because of a geographic event about 89,000 years ago. However, the UCL team found that Qomolangma is growing faster these years. They estimated (估计) this to be between 0.16 and 0.53 millimeters each year! Now the height of Qomolangma rises a little bit every year because of big forces (力量) under the ground. It is also affected by weather conditions such as ice and snow. And rivers also affect it. The Arun River, which runs close to Qomolangma, has been cutting through rocks and washing away the land over time. This makes the mountain lighter, allowing it to rise like a boat when weight is taken away. The process of this rising is isostatic rebound (地壳均衡回弹). This means the Earth’s surface moves up or down when something heavy is taken away or put on. Qomolangma is not the only mountain that changes. The UCL team said that nearby mountains, Lhotse and Makalu, the fourth and fifth highest in the world, are also growing a little bit each year.

What about Mount Denali (德纳里山) in America? Denali in Denali National Park in Alaska is the highest peak in North America. It is about 20, 308 feet above sea level. Denali is one of the most d… mountains in the Western Hemisphere for mountain climbers. Denali is closer to the North Pole (北极) than other tall mountains. This means that the air is thinner, so it’s harder for climbers. The first group of climbers got to the top of Denali in 1913. Two other groups were successful after that. The next group got to the top in 1947. This group had a husband and a wife, Bradford and Barbara Washburn. Barbara was the first woman to successfully climb the mountain. The Washburns were not climbing for sport; they were explorers. In the field of mountain mapping, Bradford Washburn was one of the best. The Washburns mapped many mountains and the Grand Canyon. Bradford dreamed of mapping Mount Qomolangma. Later they produced the best map ever made of Mount Qomolangma. 1．Where is Mount Denali? A．In Asia. B．In America. C．In Europe. D．In England. 2．What is the proper word in the sentence “Denali is one of the most d… mountains in the Western for mountain climbers.”? A．Different. B．Dark. C．Dangerous. D．Deep. 3．What is the purpose of the passage? A．To show dangerous trips. B．To compare all high mountains. C．To introduce Denali. D．To encourage some climbers. The Big Stone River is one of the most amazing stone rivers in the world. The Big Stone River is the most interesting sight (景象) of Taganay National Park in Russia. Different from other rivers, it is filled with rocks and stones. Not a drop of water can be seen. Interestingly, as one comes near to the rocky river, the sound of running water can be heard. Rocks fell down from the mountains slowly and made the river of rocks. The Big Stone River is about 6 km long and is made up of many small rocky rivers. It cuts through a thick forest like a real river. It is about 200 metres wide and in some places, it is up to 700 metres wide. Some of the rocks weigh up to 10 tons each and the layer (层) of rocks goes down 6 metres deep. Scientists believe it is the consequence of the movement of glaciers (冰川) about 10, 000 years ago. At that time, ice covered the top of the mountains. As time went by, the ice turned into water. Seeing the amazing river is a great experience. The best way to experience this natural wonder is from above. Come and visit it when you come to Russia. 1．Why is the Big Stone River special? A．Because it is in Taganay National Park. B．Because it is full of fish. C．Because it is impossible to see water there. D．Because the sound of running water is loud. 2．How wide is the widest part of the Big Stone River? A．6 metres.

After spending hours indoors, do you feel better when you visit your local park? I believe the answer must be “YES”. Most people think that nature is good for our bodies and brains. However, humans are spending more time inside and less time outside. For example, the number of visitors to Canada’s national parks is getting smaller every year. And in countries such as the USA, only 10% of teenagers spend time outside every day. Many doctors feel that this is a problem in the twenty-first century. Therefore, some doctors are studying the connection between nature and health: one example is the work of Dr. Matilda in Sweden. The doctor gave people a maths test. During the test, their heart rates(心率) were fast. After the test, one group of people sat in a 3D-virtual-reality(虚拟现实) room for fifteen minutes with pictures and sounds of nature. Their heart rates were slower than people’s in the other group. The virtual touch with nature helped them feel more relaxed. The natural world allows our brains to rest and slow down, and can leave us feeling happier and less stressed. Another example from Canada also shows nature is good for health. In Toronto, researchers studied 31,000 people living in the city. In general, they found that healthier people lived near parks. Because of studies like these, some countries and cities want people to enjoy nature in their everyday life. In Dubai, people plan to build a new shopping mall with a large garden, so shoppers can relax outside with trees, plants and water. And South Korea has new forests near its cities and around 13 million people visit these forests every year. Getting close to nature has been thought to be necessary for brain development in children. In Switzerland, “forest schools” are popular. School children study their subjects in the forests and exercise a lot outside. So after building cities for so long, perhaps it’s now time to start rebuilding nature. 1．What does the underlined word “this” in paragraph 2 refer to? A．People spend more time inside than outside. B．People think nature is good for our bodies. C．Only teenagers spend time outside every day. D．The number of people to parks changes every day. 2．After the maths test, which of the following helped slow the heart rates of people? A．The advice from the doctor. B．Pictures and sounds of nature. C．The maths problems in the test. D．The real natural world. 3．What do the results of the studies show in paragraph 3? A．The maths test is bad for health as it makes people nervous. B．People’s heart rates get slower in a 3D-virtual-reality room. C．More and more Canadians will move to live near parks. D．Nature can help people be more relaxed and healthier. 4．To help people enjoy nature, which of the following is not done by the countries? A．Building new forests near cities. B．Inventing a brain development programme. C．Planning a green area for shoppers. D．Having classes and doing sports in the forest. 5．What can we learn from the last sentence of the passage? A．Nature is more important than cities. B．Country life is healthier than city life. C．Nature should be part of people’s life. D．People have lived in cities for so long. Did you ever dream of traveling all the way over the rainbow (彩虹)? In fact, it’s easier than you think. All you need to do is to buy a plane ticket to Peru (秘鲁). The South American country is home to wonderful natural sights, and one of the most amazing is Rainbow Mountain. Rainbow Mountain, also called Mountain of Seven Colors, lies in the Andes in Cusco. As its name shows, the mountain has different colors. It attracts (吸引) lots of tourists every year. But what makes the mountain look like it is painted in yellows, greens, reds, and purples? The reason is the ice that covered the area centuries ago. When it began to melt, the water mixed with minerals (矿物质) in the ground, turning the earth into the many colors you see today. If you plan your trip to the mountain, you’d better visit it during warmer months when there will be less rain or snow. Rain or snow will make the climbing more difficult and the colors will look duller (更暗淡的). The best time begins in March and lasts nine months, when there will be blue skies and pleasant weather. At the same time, visit it in the morning or during evening hours, either right after sunrise or right before sunset. Very sunny days may prevent you from taking nice photos. To get to Rainbow Mountain, you should first go to Cusco. From the city, you can take a two-or-three-hour car ride to Pitumarca. Then you have to make your way to Qesoyuno to start the journey on foot. Once you arrive at the base (大本营), it’s about a two-or-three-hour walk to the top. This really is the best way, but the trip is very challenging. The other important thing to remember is that the mountain sits at a really high elevation (纬度) about 5,200 meters above sea level, so prepare enough water and take your time. 1．How does the writer start the passage? A．By listing a fact. B．By telling a story. C．By asking a question. D．By giving an example. 2．What does the underlined word “melt” mean in Chinese? A．融化 B．熔化 C．蒸发 D．凝固 3．Which of the following is a perfect time for a trip to Rainbow Mountain? A．At noon of a cold day in December. B．On the evening of a rainy day in August. C．On the afternoon of a snowy day in January. D．On the morning of a sunny day in September. Where can you see auroras (极光)? Iceland? The North Pole? Actually, early this December, sky lovers in cities as south as Beijing could see them, too. They enjoyed the colored lights in the night sky. Auroras come about because of the special activities of the Sun. The Sun sends out very small particles (粒子) all the time. But sometimes, it becomes more active and lets out more. The particles travel in space like a wind. When they come near Earth, they go around it. This is because the magnetic field (磁场) of Earth “protects” us from the “Wind”. At the North and South Poles, however, some particles may get in and meet with Earth’s air. Then, the particles get “excited” and have a “dance” with the air. So, we can see the moving auroras in the sky. When the “wind” is strong enough, the auroras can cover larger areas. While we feel wowed by the beautiful lights, we often ask, “Do auroras hurt us?” The answer is no. Auroras don’t hurt people’s health. But for astronauts (宇航员) in space, they need to use special ways to protect themselves from them, said Xinhua. For example, they won’t go on spacewalks when there are “sun storms”. Also, the particle storms may stop some satellites (卫星) from working, so they may bring trouble to the GPS on our smartphones. 1．Where are small particles from? A．The Sun. B．The North Pole. C．The South Pole. D．Seas. 2．How do auroras form? A．The Sun sends out active particles. B．Particles from the Sun “dance” with the air on Earth. C．The strong wind helps them travel in space. D．The magnetic field of Earth changed small particles. 3．What can we learn about “sun storms” from the last paragraph? A．“Sun storms” will kill astronauts. B．People can enjoy “sun storms” in the night sky. C．“Sun storms” can stop GPS work well. D．“Sun storms” will cause more sun activities. 4．Where can we probably read this passage? A．In a storybook. B．In a science book. C．In a diary. D．In a comic book. When we look at the Earth, we see many different things. Sometimes, you may hear people talk about landform and landscape. Are they the same thing? Let’s find out! A landform is a natural feature of the Earth’s surface. Think of big mountains that rise high up, low valleys (山谷) between hills, flat plains that go on and on, and sandy deserts. These are all landforms. They are made by nature over a long, long time. For example, mountains are formed when huge pieces of the Earth’s surface push against (撞) each other. Valleys can be made by rivers cutting through the land little by little. Each landform has a name that tells us what it looks like and how it was formed. Scientists study landforms to learn about the history of the Earth. A landscape, on the other hand, is what you see when you look at an area of land. It includes (包括) landforms, but it also has other things like plants, buildings, and lakes. Imagine standing on top of a hill. You can see green trees waving in the wind, a small village with houses, and a clear lake nearby. All these things together make up the landscape. A landscape can change rapidly. If people build new buildings or cut down a lot of trees, the landscape will look different in just a few months. Let’s take a forest in the mountains as an example. The mountain is the landform — it’s a natural feature of the Earth. But when you see the tall trees, hear the birds singing, and watch a little stream (溪流) running down the mountain, that’s the landscape. So, the key difference is this: landform is about the natural shapes of the Earth, and landscape is about the whole view of an area, including both natural and man-made things. Next time you go on a trip, try to enjoy different landforms and describe (描述) the beautiful landscapes around you! 1．Which of the following is a landform? A．A newly-built bridge. B．A flat plain. C．A group of trees. D．A small house. 2．What can we learn from the text about how mountains are formed? A．They are made by people building up the land. B．They are formed when rivers cut through the land. C．They are formed when the Earth’s plates push into each other. D．They are formed by heavy rain and strong winds. 3．What does the underlined word “rapidly” in Paragraph 3 probably mean? A．Brightly. B．Quickly. C．Powerfully. D．Quietly. 4．What does “landscape” usually include? A．Only landforms. B．Only natural things. C．Just man-made things. D．Landforms, trees, houses and lakes. 5．How does the writer explain the difference between landform and landscape? A．By telling stories. B．By listing numbers. C．By giving examples. D．By asking questions. Rainforests (热带雨林) are some of the most amazing places on Earth. They cover only about 6% of the world’s land, but are home to more than half of all living things. These dense forests are full of life, from tiny insects to large animals, and from small plants to tall trees. The rainforest has different layers. The top layer is called the emergent layer, where the tallest trees reach up to 70 meters. Below that is the canopy, a thick layer of leaves and branches that stops most sunlight from reaching the layers below. Next is the understory, with smaller trees and bushes. The bottom layer is the forest floor, where only a little sunlight gets through. Many rainforest animals have special skills to live in their layers. For example, sloths hang from the canopy branches. Their long claws help them stay there, and their slow movement helps them save energy. Toucans have big beaks to reach fruit on thin branches that can’t hold their weight. On the forest floor, jaguars use their spots to hide in the shadows while hunting. Rainforests are important for the whole world. They take in carbon dioxide (二氧化碳) and give out oxygen (氧气), which helps keep the air clean. They also help control the world’s weather. But rainforests are in danger. Every year, large areas are cut down for wood or to make space for farms. This destroys the homes of many animals and plants, and may even change the world’s climate. 1．What percentage of the world’s land do rainforests cover? A．About 6%. B．About 16%. C．About 26%. D．About 36%. 2．What does the word “dense” mean in the first paragraph? A．Dry. B．Thick with plants. C．Cold. D．Easy to walk through. 3．Why do toucans have big beaks? A．To hang from branches. B．To hide from predators. C．To reach fruit on thin branches. D．To run fast on the forest floor. 4．Put the layers of the rainforest from top to bottom. ①understory ②emergent layer ③forest floor ④canopy A．②→④→①→③ B．④→②→①→③ C．②→①→④→③ D．④→①→②→③ 5．What is the main idea of the passage? A．How animals live in the rainforest. B．The layers of the rainforest. C．Why rainforests are amazing and important. D．How to cut down rainforests. 2 同步新教材，周周有练习，月月有重点！ 1 同步新教材，周周有练习，月月有重点！ 学科网（北京）股份有限公司 $
