Length: about 6,650 km Location: Sudan, Egypt The Nile River is the longest river in the world. It's known for being the lifeblood (命脉) of Ancient Egypt. This river is famous because it was important in Ancient Egypt. Also, the Nile River is important for farming, transportation (交通) and drinking water. Length: about 2,525 km Location: India Though it isn't the largest river in Asia, the Ganges River is still well-known. This river provides millions of people with water for farming. There are nearly 150 species of fish living there today. Other animals also live in and around it, like snakes and other insects. Length: about 650 km Location: Australia You may not have ever heard of the Finke River. It's not very long and it doesn't even flow all the time. However, scientists have considered (认为) it as the oldest river in the world. That's the reason why this river is well-known! Length: about 6,400 km Location: Peru, Colombia, Brazil The Amazon River is the second-longest river in the world. But it has the largest discharge (流量) in the world, up to 219,000 m3 per second! The Congo River, with the second largest discharge, has only 20% discharge of it! The Amazon River is also well- known for having no bridges crossing it. 16.Which river is the longest one in the world according to the passage? A. The Ganges River. B. The Nile River. C. The Amazon River. D. The Finke River. 17.What is the Ganges River famous for? A. Providing water for farming and having many living things B. Being the oldest river in the world C. Having the largest discharge in the world D. Being the lifeblood of Ancient India 18.Why is the Finke River well-known? A. It flows all year round in Australia. B. It is the longest river in Australia. C. It is considered the world's oldest river. D. It has many rare fish and insects. 19.What can we know about the Amazon River? A. It is the longest river in South America. B. Its discharge is 20% of the Congo River's. C. There are many famous bridges over it. D. It runs through Sudan and Egypt. 20.Where is the passage most probably from? A. A maths book. B. A history story. C. A travel magazine. D. An Englishbook. B ①There may be no place more dangerous than Death Valley（死亡谷）. Death Valley is the hottest and the driest place in North America. ②Death Valley isn’t an easy place to live in. It gets less than two feet of rain a year and it’s hot, too. In July, temperature often gets over 46℃. Even a lake there has turned into salt crystals（晶体）. But it is cold at night. When it gets cold enough, the water on the ground will turn into thin ice. Then the strong wind—like a large hand—can move the rocks along the icy ground. That is why the rocks can “walk” on their own in Death Valley. ③The weather condition in Death Valley is terrible, but nothing can stop plants and animals from making it their home. People have found more than 1,000 kinds of plants there. It also has 51 kinds of mammals（哺乳动物）, 6 kinds of fish, and more than 300 kinds of birds. The animals aren’t all small, either. ④Finding water is the biggest challenge for anything that lives here. To survive, some plants’ roots（根部）can go fifty feet under the ground to find water. Kangaroo rats（更格卢鼠）get the water they need from flowers. ⑤Death Valley really makes a lot of surprise! 21.Why can the rocks “walk” on their own in Death Valley? A. Because it gets less than two feet of rain a year in Death Valley. B. Because the water on the ground will turn into thin ice. C. Because the strong wind can move the rocks along the icy ground. D. Because the weather condition in Death Valley is really terrible. 22.How does the writer develop（展开）his idea in Paragraph 4? A. By giving examples. B. By asking questions. C. By giving advice. D. By telling stories. 23.What can we learn from the passage? A. The writer doesn’t like Death Valley. B. Some animals are large in Death Valley. C. The plants do not have long roots. D. Rocks sometimes move in the afternoon. 24.What’s the structure（结构）of the passage? 25.What is the best title of this passage? A. The hard life in Death Valley B. A dangerous place—Death Valley C. The facts about Death Valley D. Moving rocks in Death Valley C The Amazon Rainforest is the world’s biggest rainforest. It is in South America. It is so wide that it covers a little more than the half size of China! The Amazon River runs through the rainforest. It’s the world’s second longest river. The Amazon Rainforest covers much of Brazil. The green colour on the national flag of Brazil stands for the rainforest. However, climate change and human activities make it “sick”. Usually, the rainforest can fix itself. But now, it feels too “tired” to get better. According to a new study, many trees there may die, and the Amazon Rainforest may turn into hot, dry grassland in a few years. Why is the Amazon “sick”? The Amazon Rainforest is one of the world’s wettest places. But since 2005, three droughts have hit the rainforest. They were caused by climate change. The trees don’t have enough water to grow. What’s worse, as they become dry, they can easily catch fire. Besides, people cut down rainforest trees for wood. They burn the forest to make farmland. All these kinds of activities have made about of the rainforest disappear. What will happen if we lose the Amazon Rainforest? The Amazon Rainforest is like the lungs (肺) of our planet. The rich plants there take out of the air and make oxygen (氧气). They make more than of the planet’s oxygen. If the Amazon Rainforest “dies”, there will be more , and our earth will become even hotter. The Amazon Rainforest is also home to over 3 million animals and plants. Many of them can’t live anywhere else. They would very likely just disappear. 26.What do we know about the Amazon Rainforest from the first paragraph? A. It is smaller than half the size of China. B. The Amazon River is the world’s longest river. C. It is the world’s largest rainforest. D. The white colour on Brazil’s flag stands for it. 27.What does the underlined word “droughts” mean? A.Too little rain. B.Too little snow. C. Too much rain. D. Too much fire. 28.Why does the writer say the Amazon Rainforest is “sick”? A. Because it is too small to provide enough oxygen. B. Because it is hurt by climate change and human activities. C. Because there are no enough animals living in it now. D. Because the Amazon River stops running through it. 29.What’s the writer’s purpose of talking about “lungs of our planet”? A. To show the Amazon Rainforest is important for the earth’s air. B. To tell readers the rainforest has the same shape as lungs. C. To explain how plants take in oxygen from the air. D. To prove the rainforest is the wettest place on the earth. 30.What can we infer from the passage? A. The Amazon Rainforest can never fix itself again. B. Droughts are the only reason for the rainforest’s problems. C. Losing the Amazon Rainforest will bring great harm to the earth. D. People will stop cutting down trees in the Amazon Rainforest soon. 第二节：阅读还原（每小题2分，共10分） Fifteen-year-old Alkut Dilxat became the youngest Chinese climber to reach the summit（峰顶）of Qomolangmaon May 19, 2024.

This vast desert, also known as "the great desert" in Arabic, is about 9 million square kilometres in size. lt is also at least 4.6 million years old. All deserts are dry, and the Sahara is both dry and hot. lt is the largest hot desert in the world. We may think that all deserts are hot, but in fact some deserts are very cold! Many scientists believe that Antarctica, for example, is a type of cold desert. Most of the Sahara is rocky ground. But there are also places with grass, lakes, mountains, and even sand seas. A sand sea is just what it sounds like---it looks like a sea of sand! When the wind blows, the sand looks like waves. Life in the Sahara is diffcult. About two million people live in the Sahara. They usually move from place to place. There is water in a few parts of the Sahara, and some people live in these places all year round. Not many animals can live in a place with such a dry and hot climate. They must adapt to survive. Camels, for example, go for a long time without drinking water. When they do find water, they can drink more than 100 litres of it in 13 minutes! Today, the world’s largest hot desert is getting even bigger. Climate change brings hotter summers and less rain in Africa. If we do not take effective measures to stop climate change, the desert will keep growing! 46&49.Fill in the blanks acocording to the passage. Location Located in 46.______(仅填1词).
