Passage 5
As we all know, climate change has greatly influenced the birds’ living environment. Take Poyang Lake as an example. As an important habitat for the seriously endangered birds, Poyang Lake has experienced unusual rises and falls in recent years.
“In some years, the lake experiences floods, while in others it experiences a shortage of rain. Both of these situations lead to less food in the birds’ habitat,” a scientist told China Daily.
To solve such habitat problems, China has named about 1,000 places these years as important living and winter places in wetlands. To protect China’s wetlands, a law was also made in 2022 to control human activities. According to the law, people can’t overuse the wetlands. What's more, they can’t pour (倒) waste water into the wetlands.
Since these methods have worked well, more birds have been seen living in the nation’s wetlands. In February, Hunan Province reported that more than 70 kinds of water birds had spent the past winter at Dongting Lake, and that the number of one endangered kind of birds had increased from 300 in the 1980s to more than 5,000 at present. All of these cases show a better future.

Passage 7
① There may be no place more dangerous than Death Valley (死亡大峡谷). Death Valley is the hottest and 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, the temperature often gets over 46℃. There is even a lake that 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 very 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 (状况) in Death Valley is terrible, but it is still full of life. 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 there. Some plants have roots that 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 surprises!

Passage 10
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。
Passage 11
Sunshine, beaches and coconuts (椰子) —these are why people usually go to Hainan. But more than a good place for travelers and foodies, it’s also a wonderland of plants and animals.
Hainan Tropical Rainforest National Park in the south-central part of Hainan Island, has the most and well-kept tropical rain forests in China. President Xi Jinping visited it in April, 2023. The national park covers 4, 269 square kilometers, or one-seventh of the island. More than 95percent of the park is virgin (原始的) forest and is home to 3,653 species (种类) of vascular plants and 540 species of terrestrial vertebrates.
The park is the only home of the world’s most endangered primate (灵长类动物)—the Hainan gibbon. It’s an uncommon species. They look like monkeys, but have no tails. They live in the trees their whole life. Every morning, they whistle loudly to mark their territory (领地) . They eat fruits and leaves from more than 130 plants. The number of Hainan gibbons has become larger from fewer than 10 in the 1980s to 36 in 2022. This shows China’s achievements in environmental protection.
Not just a sweet home to animals, the park is a “live museum” of amazing plants. More than 400 kinds of plants grow only in Hainan. Cycas hainanensis (海南苏铁) is a wild plant native to the island. With feather-like leaves, this plant can live to be 200 years old. If it lives in the Yangtze River Basin and North China, it grows almost without flowers or fruit. But in Hainan, cycas hainanensis plants over 10 years old blossom (开花) and have fruit almost every year, thanks to the warm and wet weather.
With so many plants and animals, the biodiversity index (指数) of the park—a number to rate species diversity—is as high as 6.28. It is comparable (可比较的) to the Amazon rainforest in Brazil. That’s why people call the park a treasure for both China and the world.
1. Paragraph 3 is mainly about ________.
A.an introduction to the park B.the views of the park
C.the news of the park's opening D.details of rare plants and animals
2. What do we know about the Hainan gibbon?
A.It is a monkey without a tail. B.Its voice sounds like a crying baby.
C.It lives on plants and birds. D.It is a species only found in Hainan.
3. From the story, we can infer that a cycas hainanensis plant ________.
A.never blossoms and has fruit B.can only live for 10 years in Hainan
C.lives better in warm and wet weather D.first blossoms when it is 10 years old
4. Which of the following may be the writer’s opinion?
A.Human activities will surely hurt the rainforest.
B.We must start to do something for rare species.
C.China has done a great job in protecting the rainforest.
D.We should compare our rainforest with the Amazon rainforest.

Passage 12
He Jibai, a nature lover, lives on a beautiful island in east China’s Zhejiang Province. For three years, he has worked as a seabird monitor. His job is to watch and protect seabirds, especially the Chinese crested tern (中华凤头燕鸥), a rare bird in danger of disappearing. He watches them closely— from the time they arrive and lay eggs to when their chicks grow and leave.
He Jibai loved observing nature since he was a child. After working in biodiversity research, he joined this special programme in 2023. His daily tasks include checking the birds’ homes, controlling rats that might harm them, and watching for sick birds. Though the work can be repetitive (重复乏味的), he enjoys it because it matches his love for nature.
The Chinese crested tern is very rare, with fewer than 200 left in the world. The monitors also look after other animals, like the great crested tern and the Eurasian otter (欧亚獭). Their efforts help scientists learn more about these creatures and how to protect them. Last year, over 3, 000 people applied for this job, but only 11 were chosen, showing how popular it has become.
Every April, many birds fly through the island. The team records them to understand their travel patterns. This information helps make better plans to save seabirds. Thanks to years of hard work, the number of Chinese crested terns has grown from fewer than 50 in 2010 to about 100 in 2022. Most of them now live in Zhejiang, making it a key place for their survival.
He Jibai and his team are proud to protect these birds. Their work not only saves seabirds but also teaches people about the importance of caring for nature.

Passage 13
Wetlands, the “Earth’s kidneys,” are vital for a healthy planet. They clean our water and provide homes for wildlife. But for a long time, humans saw them as useless land, filling them in for farms and cities, which caused water pollution and loss of animal homes.
Thankfully, the story is changing. People now understand the importance of wetlands and are working to bring them back. A great example is the creation of wetland parks in China, like the Xixi National Wetland Park in Hangzhou. It shows how humans and nature can live in harmony (和谐).
Protecting wetlands starts with us. We can begin by learning about the wetlands near us and the life they support. A visit to a wetland park can help us see their beauty and understand their value firsthand. In our daily lives, saving water is also a powerful way to help, as using less water means more clean water can flow to these areas. Finally, sharing what we’ve learned with friends and family can spread the message of conservation further.
By taking these steps, we can all be part of protecting these wonderful places. Protecting wetlands is not just about saving nature; it is about protecting our own future.

Passage 14
When I was a child, things were not good for animals. People liked visiting zoos, but I didn’t. Some people might find the dolphins’ tea parties funny or the bird shows enjoyable, but I didn’t. It seemed that the animals were in a circus (马戏团).
I was upset when circus people played games on animals—men making fun of lions, girls walking on elephants, monkeys playing football and so on. I thought those things were just cold and cruel. However, we didn’t have the law to stop the bad things.
Happily, as time went by, laws were starting to play their roles in animal care and people began to stand on the animals’ side. Circuses could not use wild animals for making money any more and zoos couldn’t either.
When my children were young, I sometimes took them to our local zoo. The elephants were in small cages and the monkeys looked bored as they sat peeling bananas. As a result, animal lovers are often against zoos. They say animals should get back to nature. However, zoo animals have a longer life. They are just not free. Yes, they are not free to be killed, not free to die of hunger or thirst. Maybe sitting in a cage eating bananas isn’t so bad.
There are even bigger changes. Many kinds of animal-care groups keep joining in and giving help. Our thanks should go to BIAZA, an association for saving wildlife across the world. BIAZA tells zoos what to do in special situations; it keeps an eye on how animals live both in and out of the zoos; it studies animals and helps other animal-study programmes, both in the UK and abroad; it gives animal-care talks to teach people about animals. Also, it organizes animal exchange programmes between zoos to help people around the world see different animals.
Today, most zoo animals are born and grow up in large comfortable places. Kind and experienced zoo workers look after them. Sometime in the future these animals may get back to nature and really share this planet with humans. We should always care about them and remember that humans aren’t the owners of this planet.
1. From Paragraph 2, we can see that the writer believed circus animals ________.
A.were talented in games
B.lived a terrible life
C.were cold and cruel
D.liked working with people
2. According to the passage, BIAZA probably can’t ________.
A.share ideas about how to care for animals
B.help some animal-study programmes
C.close zoos when animals die due to something special
D.borrow a panda from China and bring it to London Zoo
3. According to the passage, the writer would agree that ________.
A.zoo animals should go back to nature at once
B.humans are not good at taking care of animals
C.humans are the owners of the planet
D.zoos now have better living environment for animals
4. What is the structure of the passage?

Passage 15
Water is important for all living things on Earth. The water cycle (循环) is a natural process that takes water from the ground and the sky and brings it back to the earth again. It is a cycle that happens the whole year and is most active from March to June in China. In this article, we will learn about the water cycle and discuss its importance for Earth.
The water cycle always begins with water vapour (蒸汽). When it’s hot outside, you can see clouds forming in the sky. These clouds are made of water vapour that comes from the ground, plants and rivers. As water vapour rises into the sky, it cools down and becomes clouds. After that, clouds travel through the sky and fall back to Earth as rain or snow. Then, water runs through rivers and oceans and finally returns to the earth again in different forms like rainwater or snow.
The water cycle is important in protecting our Earth’s climate (气候). It provides us with water to drink and keeps our climate healthy. On top of that, it takes water from rivers and oceans and brings it to the areas that don’t have enough water. Without the cycle, we would face many problems. When there is too much water in one place, it becomes a flood. When water is badly in need, it becomes a drought. Besides, water vapour can take heat from the sun and keep our Earth cool. The water cycle is a natural process that keeps our Earth alive. It’s important for plants and animals to drink water and for our rivers to stay flowing with water.
Understanding the water cycle can help us enjoy the beauty of nature, know how our Earth works and find better ways to protect our Earth and that is our duty.
1. Which season has the most active water cycle in China.
A.Spring B.Summer C.Autumn D.Winter
2. Which is the right order of the water cycle according to the passage?
a. Water returns to the ground. b. Rain or snow falls down.
c. Water vapour rises up. d. Clouds are formed in the sky.
A.c-b-d-a B.c-d-b-a C.d-c-b-a D.d-b-c-a
3. Why is the water cycle is important?
A.Because it brings people warm weather. B.Because it cleans the air and the ground.
C.Because it makes the climate healthy. D.Because it shows the beauty of nature.
4. Which shows the structure of the passage?
A. B. C. D.
【答案】1. A 2. B 3. C 4. A

Passage 2
Snow fell on the mountain. It snowed and snowed. The snow did not melt(融化). It became deep and heavy. The snow on the bottom pressed (挤压) together, it became ice.
The ice was very wide and thick. It began to move down the mountain. It was like a river of ice. It was a glacier(冰河).
Sometimes the glacier moved only a few inches(英寸) each day. As it moved, it took rocks and dirt with it. It changed the land. In some places, it left hills. In some places, when the glacier melted, it made rivers and lakes.
A million years ago, there were many big glaciers. Glaciers covered many parts of the world. The glaciers changed the land.

Do you know what the world’s highest waterfall is? You may say that it is Niagara Falls. Niagara Falls is really beautiful, but in terms of the height, the most fantastic one in the world is Angel Falls. It’s deep in the jungles (丛林) of Venezuela.
Few people have ever seen Angel Falls. It’s very hard to get there. If you go there on foot, you have to travel for weeks through thick jungles. If you go by plane from Caracas, a city on the southern coast, it will take about four hours.
One of the most interesting facts about Angel Falls is how they were found. It was named after an American pilot. His name was Jimmy Angel. In 1937, his plane crashed (坠毁) near the top of the falls. That’s how he found it.

The Amazon River begins in the Andes Mountains in South America. It passes through six countries. The Amazon is the second longest river in the world. But the Amazon has more water in it than any other river. That is why it is called the world’s biggest river.
There are so much water in the Amazon that when it reaches the sea, the water travels far out into the ocean. The river is very deep and very wide. In some places it is so wide that a person on one side cannot see the other side. When the river floods, it is even wider. The river floods every year. So some people who live beside the river build their houses on rafts.
There are millions of fish in the Amazon River. One of these is the piranha (水虎鱼) with its very sharp teeth. Piranhas hunt in group. They usually eat other fish, but sometimes they attack large animals or even people.

Passage 5
As we all know, climate change has greatly influenced the birds’ living environment. Take Poyang Lake as an example. As an important habitat for the seriously endangered birds, Poyang Lake has experienced unusual rises and falls in recent years.
“In some years, the lake experiences floods, while in others it experiences a shortage of rain. Both of these situations lead to less food in the birds’ habitat,” a scientist told China Daily.
To solve such habitat problems, China has named about 1,000 places these years as important living and winter places in wetlands. To protect China’s wetlands, a law was also made in 2022 to control human activities. According to the law, people can’t overuse the wetlands. What's more, they can’t pour (倒) waste water into the wetlands.
Since these methods have worked well, more birds have been seen living in the nation’s wetlands. In February, Hunan Province reported that more than 70 kinds of water birds had spent the past winter at Dongting Lake, and that the number of one endangered kind of birds had increased from 300 in the 1980s to more than 5,000 at present. All of these cases show a better future.

Passage 7
① There may be no place more dangerous than Death Valley (死亡大峡谷). Death Valley is the hottest and 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, the temperature often gets over 46℃. There is even a lake that 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 very 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 (状况) in Death Valley is terrible, but it is still full of life. 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 there. Some plants have roots that 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 surprises!
1. Death Valley is the ________ place in North America.

The Hutuo River is the mother river of Shijiazhuang, the capital city of Hebei Province. About 20 years ago, it was dirty and almost dried up. Thanks to the government’s (政府的) work, it becomes clean now.
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 must cross the river by boat at that time. But later, it got dirty and started to dry up.
To remediate (修复) the river, the government do a lot of things. They clean the river up and build levees (防洪堤). They plant trees, grass and flowers. They set up fences (防护栏) and stick “No Swimming” signs along the river to protect people. They ask people not to put dirty water into the river. They also have a long-term plan to protect the river.
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.

Passage 9
You must have heard of the legend (传说) of Yu Gong, who tried to move two mountains. The Taihang Mountain was one of the two mountains.
The Taihang Mountain passes through the areas of Hebei, Shanxi, Henan and Beijing. It is about 400 kilometers long. It is one of the largest mountain ranges in North China, and it was called “the backbone (脊梁) of China” in ancient times.
Many legends about the beginning of human civilization (文明) come from the Taihang area. For example, Nvwa used stones to repair the sky to make sure that humans would have a better future; Houyi protected everyone by shooting the suns.
The Taihang Mountain is not only where the ancient stories happened, but also a place where tens of thousands of fossils (化石) were found. These fossils show how the earth has changed over time. At the same time, we can also learn about how ancient humans lived from the discoveries around the area.
Nowadays, there are natural forests around the area with beautiful colors in four seasons. In spring, the trees of Taihang Mountain will grow green leaves. In summer, the trees will grow luxuriant (挺拔的) and leaves will cover the sun. In autumn, the trees in Taihang Mountain are tall and leaves turn yellow. In winter, the trees are covered with snow, like a thick white coat. You can go there whenever you want because it is beautiful all year round.
If you want to learn different things about history, culture and other important knowledge, you can come to the Taihang Mountain and feel its greatness.

Passage 10
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.
Passage 11
Sunshine, beaches and coconuts (椰子) —these are why people usually go to Hainan. But more than a good place for travelers and foodies, it’s also a wonderland of plants and animals.
Hainan Tropical Rainforest National Park in the south-central part of Hainan Island, has the most and well-kept tropical rain forests in China. President Xi Jinping visited it in April, 2023. The national park covers 4, 269 square kilometers, or one-seventh of the island. More than 95percent of the park is virgin (原始的) forest and is home to 3,653 species (种类) of vascular plants and 540 species of terrestrial vertebrates.
The park is the only home of the world’s most endangered primate (灵长类动物)—the Hainan gibbon. It’s an uncommon species. They look like monkeys, but have no tails. They live in the trees their whole life. Every morning, they whistle loudly to mark their territory (领地) . They eat fruits and leaves from more than 130 plants. The number of Hainan gibbons has become larger from fewer than 10 in the 1980s to 36 in 2022. This shows China’s achievements in environmental protection.
Not just a sweet home to animals, the park is a “live museum” of amazing plants. More than 400 kinds of plants grow only in Hainan. Cycas hainanensis (海南苏铁) is a wild plant native to the island. With feather-like leaves, this plant can live to be 200 years old. If it lives in the Yangtze River Basin and North China, it grows almost without flowers or fruit. But in Hainan, cycas hainanensis plants over 10 years old blossom (开花) and have fruit almost every year, thanks to the warm and wet weather.
With so many plants and animals, the biodiversity index (指数) of the park—a number to rate species diversity—is as high as 6.28. It is comparable (可比较的) to the Amazon rainforest in Brazil. That’s why people call the park a treasure for both China and the world.
1. Paragraph 3 is mainly about ________.
A.an introduction to the park B.the views of the park
C.the news of the park's opening D.details of rare plants and animals
2. What do we know about the Hainan gibbon?
A.It is a monkey without a tail. B.Its voice sounds like a crying baby.
C.It lives on plants and birds. D.It is a species only found in Hainan.
3. From the story, we can infer that a cycas hainanensis plant ________.
A.never blossoms and has fruit B.can only live for 10 years in Hainan
C.lives better in warm and wet weather D.first blossoms when it is 10 years old
4. Which of the following may be the writer’s opinion?
A.Human activities will surely hurt the rainforest.
B.We must start to do something for rare species.
C.China has done a great job in protecting the rainforest.
D.We should compare our rainforest with the Amazon rainforest.
Passage 12
He Jibai, a nature lover, lives on a beautiful island in east China’s Zhejiang Province. For three years, he has worked as a seabird monitor. His job is to watch and protect seabirds, especially the Chinese crested tern (中华凤头燕鸥), a rare bird in danger of disappearing. He watches them closely— from the time they arrive and lay eggs to when their chicks grow and leave.
He Jibai loved observing nature since he was a child. After working in biodiversity research, he joined this special programme in 2023. His daily tasks include checking the birds’ homes, controlling rats that might harm them, and watching for sick birds. Though the work can be repetitive (重复乏味的), he enjoys it because it matches his love for nature.
The Chinese crested tern is very rare, with fewer than 200 left in the world. The monitors also look after other animals, like the great crested tern and the Eurasian otter (欧亚獭). Their efforts help scientists learn more about these creatures and how to protect them. Last year, over 3, 000 people applied for this job, but only 11 were chosen, showing how popular it has become.
Every April, many birds fly through the island. The team records them to understand their travel patterns. This information helps make better plans to save seabirds. Thanks to years of hard work, the number of Chinese crested terns has grown from fewer than 50 in 2010 to about 100 in 2022. Most of them now live in Zhejiang, making it a key place for their survival.
He Jibai and his team are proud to protect these birds. Their work not only saves seabirds but also teaches people about the importance of caring for nature.

Passage 13
Wetlands, the “Earth’s kidneys,” are vital for a healthy planet. They clean our water and provide homes for wildlife. But for a long time, humans saw them as useless land, filling them in for farms and cities, which caused water pollution and loss of animal homes.
Thankfully, the story is changing. People now understand the importance of wetlands and are working to bring them back. A great example is the creation of wetland parks in China, like the Xixi National Wetland Park in Hangzhou. It shows how humans and nature can live in harmony (和谐).
Protecting wetlands starts with us. We can begin by learning about the wetlands near us and the life they support. A visit to a wetland park can help us see their beauty and understand their value firsthand. In our daily lives, saving water is also a powerful way to help, as using less water means more clean water can flow to these areas. Finally, sharing what we’ve learned with friends and family can spread the message of conservation further.
By taking these steps, we can all be part of protecting these wonderful places. Protecting wetlands is not just about saving nature; it is about protecting our own future.
1. Why are wetlands called the “Earth’s kidneys”?
A.Because they are shaped like kidneys. B.Because they are home to many animals.

2. What is the correct order of the advice given in the passage on how to protect wetlands?
a. Tell others about it. b. Save water in daily life.
c. Learn about local wetlands. d. Visit a wetland park.
A.a c b d B.c d b a C.b a d c D.d c a b
3. What is the special part about the Xixi National Wetland Park according to the passage?
A.It keeps all its birds in large cages for visitors.
B.It is the largest wetland park in the world.
C.It successfully balances nature protection and human enjoyment.
D.It does not allow any visitors to enter in order to protect nature.
4. What is the writer’s main purpose in writing this passage?

Passage 14
When I was a child, things were not good for animals. People liked visiting zoos, but I didn’t. Some people might find the dolphins’ tea parties funny or the bird shows enjoyable, but I didn’t. It seemed that the animals were in a circus (马戏团).
I was upset when circus people played games on animals—men making fun of lions, girls walking on elephants, monkeys playing football and so on. I thought those things were just cold and cruel. However, we didn’t have the law to stop the bad things.
Happily, as time went by, laws were starting to play their roles in animal care and people began to stand on the animals’ side. Circuses could not use wild animals for making money any more and zoos couldn’t either.
When my children were young, I sometimes took them to our local zoo. The elephants were in small cages and the monkeys looked bored as they sat peeling bananas. As a result, animal lovers are often against zoos. They say animals should get back to nature. However, zoo animals have a longer life. They are just not free. Yes, they are not free to be killed, not free to die of hunger or thirst. Maybe sitting in a cage eating bananas isn’t so bad.
There are even bigger changes. Many kinds of animal-care groups keep joining in and giving help. Our thanks should go to BIAZA, an association for saving wildlife across the world. BIAZA tells zoos what to do in special situations; it keeps an eye on how animals live both in and out of the zoos; it studies animals and helps other animal-study programmes, both in the UK and abroad; it gives animal-care talks to teach people about animals. Also, it organizes animal exchange programmes between zoos to help people around the world see different animals.
Today, most zoo animals are born and grow up in large comfortable places. Kind and experienced zoo workers look after them. Sometime in the future these animals may get back to nature and really share this planet with humans. We should always care about them and remember that humans aren’t the owners of this planet.
1. From Paragraph 2, we can see that the writer believed circus animals ________.
A.were talented in games B.lived a terrible life
C.were cold and cruel D.liked working with people
2. According to the passage, BIAZA probably can’t ________.
A.share ideas about how to care for animals

3. According to the passage, the writer would agree that ________.
A.zoo animals should go back to nature at once
B.humans are not good at taking care of animals
C.humans are the owners of the planet
D.zoos now have better living environment for animals
4. What is the structure of the passage?
A.①②/③④/⑤⑥ B.①②/③④⑤/⑥
C.①/②③④⑤/⑥ D.①/②③④/⑤⑥
Passage 15
Water is important for all living things on Earth. The water cycle (循环) is a natural process that takes water from the ground and the sky and brings it back to the earth again. It is a cycle that happens the whole year and is most active from March to June in China. In this article, we will learn about the water cycle and discuss its importance for Earth.
The water cycle always begins with water vapour (蒸汽). When it’s hot outside, you can see clouds forming in the sky. These clouds are made of water vapour that comes from the ground, plants and rivers. As water vapour rises into the sky, it cools down and becomes clouds. After that, clouds travel through the sky and fall back to Earth as rain or snow. Then, water runs through rivers and oceans and finally returns to the earth again in different forms like rainwater or snow.
The water cycle is important in protecting our Earth’s climate (气候). It provides us with water to drink and keeps our climate healthy. On top of that, it takes water from rivers and oceans and brings it to the areas that don’t have enough water. Without the cycle, we would face many problems. When there is too much water in one place, it becomes a flood. When water is badly in need, it becomes a drought. Besides, water vapour can take heat from the sun and keep our Earth cool. The water cycle is a natural process that keeps our Earth alive. It’s important for plants and animals to drink water and for our rivers to stay flowing with water.
Understanding the water cycle can help us enjoy the beauty of nature, know how our Earth works and find better ways to protect our Earth and that is our duty.
1. Which season has the most active water cycle in China.
A.Spring B.Summer C.Autumn D.Winter
2. Which is the right order of the water cycle according to the passage?
a. Water returns to the ground. b. Rain or snow falls down.
c. Water vapour rises up. d. Clouds are formed in the sky.
A.c-b-d-a B.c-d-b-a C.d-c-b-a D.d-b-c-a
3. Why is the water cycle is important?
A.Because it brings people warm weather. B.Because it cleans the air and the ground.
C.Because it makes the climate healthy. D.Because it shows the beauty of nature.
4. Which shows the structure of the passage?
A. B. C. D.
