Unit 5 Save the endangered animals
单元话题阅读理解练习
（22-23八年级下·广东深圳·期中）Once there were many thousands of Gourma Desert （沙漠）elephants in Mali, a country in West Africa. Now, there are fewer than four hundred.
Why did the number of the elephants drop so quickly On the one hand, the elephant’s main lake, their only water source, dried up. On the other hand, the land which the elephants lived on was overused by humans.
To protect the elephants’ living environment, the Mali Elephant Project（MEP） was started in 2007. MEP met with local people and helped them make rules of using land and water. As a result, the situation became better and there was more food, forest and grassland.
However, from 2012 to 2016, poaching（偷猎）and illegal trade in the elephants increased rapidly. Eighty-three elephants were lost in 2015 alone and another fifty-one elephants were killed in 2016. “If this situation goes on, all the Gourma elephants will be killed by 2020,” said a member of MEP.
Luckily, the voice of MEP was heard. More organizations have joined together to educate the local people that trading elephants is against the law. Elephant poaching has dropped to a very low level. The local people have learned to live peacefully with the elephants, one of the wildlife treasures in the world.

（22-23八年级上·广东深圳·期中）Chinese scientists have discovered a new kind of dinosaur that lived 200 million years ago in what is today Southwest China’s Yunnan Province. The scientists plan to carry out further research into how the dinosaur moved and its family relationships.
Some fossils of the dinosaur were found several years ago in Yuxi, Yunnan Province, but they were not enough to make sure what kind of dinosaurs they are. However, the recent discovery has provided enough fossil materials to identify it as Asia’s earliest known thyreophoran dinosaurs(覆盾甲龙) for the first time.
The research team at the School of Life Sciences in Yunnan University has their research printed in the magazine e-Life. “It is such a meaningful discovery that our team can’t wait to have a deep research on it. The newly found dinosaur will be good for our study of the living environment after disappearance of some creatures from 250 million BC to 200 million BC,” said Xu Xing, one of the researchers.
According to the study, the dinosaur was about 3 meters long with four legs. At the same time, it could use its two front legs to catch the leaves of plants when needed. Recent study has shown that this dinosaur’s group spread rapidly, reaching all around the world within 10,000 years. Besides, the fossils provide evidence(证据) for how the different parts of the Earth moved at that time.
The team plans to take some parts from the fossil to study how the dinosaur grew and to build a 3D model to study how it moved. “The current fossil is still not fully complete. After we fill in the missing pieces, we can also make a 3D printed model for public education. Yunnan is the kingdom of dinosaurs, so we believe that other unnamed dinosaurs will also be discovered in this place” said Xu.
6．When did the newly found dinosaur lived
A．10,000 years ago. B．200 million years ago.
C．250 million years ago. D．20,000 years ago.
7．What does the discovery bring to the researchers
A．Some ffossils found in Yunnan University.
B．Some reasons for the disappearance of dinosaurs.
C．A chance to learn the future environment.
D．A record as the earliest known thyreophoran dinosaurs in Asia.
8．Which of the following statement is true
A．Some fossils of the dinosaur were found in Hunan Province.
B．The research team has their research printed in the magazine e-Life.
C．According to the study, the dinosaur was about 30 meters long with four legs.
D．This dinosaur’s group reached all around the world within 100,000 years.
9．What can we learn from the last paragraph
A．They team will make a 3D film about the dinosaur.
B．They team will find all the dinosaurs in Yunnan Province.
C．They team will make the dinosaur model educational.
D．They team will study why the dinosaur is not fully complete.
10．What is the structure of the passage

（22-23八年级下·广东广州·期末）An endangered species is a group of animals that could soon die out. Many species could disappear very soon if we don’t do anything to save them. There are many reasons why species become endangered but most of them are because of humans. However, there are things that we can do to save endangered species.
Habitat（栖息地）destruction is the main reason why animals become endangered. When humans move into a new area, the animals’ habitat is destroyed and there is nothing to eat because humans cut down trees and build houses and farms.
Endangered species are also the result of overhunting and overfishing. Some seal species are endangered because they are killed for their fur to make coats. Tigers are shot to make medicine and crocodiles are caught to make bags and shoes. Other animals are killed for their fur, bones or skin, or just for sports. Overfishing means that large sea animals like whales and sharks have all become endangered species, because too many are caught to make things like shark’s fin soup.
So what can people and governments do to protect animals and stop species from becoming endangered We should not pollute natural areas, and the public can help by not buying any products that are made from animals’ body parts, such as seal fur coats or crocodile bags. Governments can help, too, by making it against the law to hunt, fish, buy or sell endangered species. They can also provide money for nature reserves and zoos. If we all work together by taking these steps, we will protect our planet so that our children and their children can keep
living in harmony with other creatures, too.
11．What is the writing purpose of this passage
A．To call for actions to save endangered animals. B．To explain why animals are endangered.
C．To introduce different endangered animals. D．To tell why we need to protect endangered animals.
12．What does the underlined word “destruction” in Paragraph 2 probably mean
A．development B．protection C．damage D．pollution
13．What can we learn from this passage
A．Human’s movement is good for animals’ habitat.
B．Governments can hardly help stop species from becoming endangered.
C．Some seal species are killed to make medicine.
D．Human activities are the main reason why animals are endangered.
14．Which of the following best shows the structure of the passage (P1=paragraph 1)
A． B． C． D．
（21-22八年级下·广东广州·期末）
Dinosaurs weren’t the only animals that lived millions of years ago. Other creatures also lived on Earth. But then a huge planet hit the Earth. Dust from the explosion(爆炸) filled the air, forming cold and dark environment for living things for a long time. Green plants died, so animals could not find food. Most of the dinosaurs died out, but some fish and birds were still alive. One of them was a large fish called a sturgeon.
Most sturgeons live in rivers and lakes. They are bottom-feeders. They eat small living things that live in the sand and earth. Even in the very cold weather, sturgeons can find food. In this way, they have lived on for millions of years.
The past 100 years have brought a new challenge for these fish. People around the world like to eat delicious eggs of some fish. These eggs are called caviar. The most popular kind of caviar is sturgeon eggs. Since people ate millions of sturgeon eggs, few babies were born.
By the 1990s, sturgeons almost disappeared. New laws stopped overfishing and controlled the selling of caviar. Protections like these help sturgeon’s population grow again, but it will take a long time. These ancient fish have been around millions of years. ________
15．According to the passage, we can know that the sturgeon can live ________.
A．in an explosion B．in cold and darkness
C．without food D．without water

（22-23八年级上·广东广州·阶段练习）Monarch butterflies from eastern Canada make the most amazing journey in the insect world. Each year, this butterfly travels about 3000 miles to its winter home in central Mexico. How can it fly so far And why does it make this long and dangerous trip Scientists still don’t have an answer.
For many years, people in Mexico wondered where the orange-and-black butterflies came from every winter. Then, in 1937, a scientist started to follow and study the butterflies. For the next 20 years, he discovered that one butterfly started its journey in Canada. Four months later, it arrived in Mexico.
The length of the butterflies find their way back to the same place Another amazing thing is that the butterflies always return to the same area in central Mexico.
How do the butterflies find their way back to the same place This is an interesting question because only every fourth generation（代）makes the trip south. In other words, the butterfly that travels to Mexico this year is the great-great-grandchild of the butterfly that traveled there last year.
Each year, four generations of a Monarch butterfly family are born. Each generation of the family has a very different life. The first generation is born in the south in late April. It slowly moves north, reproduces（繁衍）, and then dies. On the trip north, two more generations are born, reproduce, and die. Each of these generations of butterflies is born. This generation has a much longer life. It lives for about eight months. This generation of butterflies makes the amazing journey back to the winter home of its great-great-grandparents. The butterflies spend the winter there, and in the spring they reproduce and then die. Their offspring will be the first generation of the next circle of life.
Today, people are still studying the Monarch butterfly. But they are not clear about everything.
19．The best title of the passage can be ________.
A．Family of Monarch butterflies B．Mystery of Monarch butterflies
C．Monarch butterflies’ birthplace D．Monarch butterflies’ winter home
20．We know that the ________ generation of Monarch butterflies travel back to central Mexico.
A．first B．second C．third D．fourth
21．The underlined word “offspring” in the passage is closest in meaning to ________.

（21-22八年级下·广东广州·期中）Believed to have existed for more than 60 million years, crested ibises（朱鹮）are one of the oldest species of bird on Earth. Due to pollution and other human activities, the birds began to disappear in the 1960s.
In 1981, seven crested ibises were found in Yangxian county in Hanzhong, Shaanxi province. They were believed to be the last remaining ones worldwide.
But now, they have been saved from extinction（灭绝）. May 23 marked the 40th anniversary of the rediscovery of the crested ibis. Researchers said that the number has risen to more than 5,000 worldwide. There are 3,000 crested ibises in Yangxian county alone.
The bird’s survival owes to China’s early protection efforts, according to Zhang Yueming, an expert who helps protect the birds in Yangxian.
On the fourth day after the discovery of the seven crested ibises, the local government put out a series of notices to protect crested ibises. For example, hunting, cutting down trees, setting off explosives（爆炸物）in the mountains, or using fertilizers（肥料）in the birds’ natural habitat are banned.
Later, it also set up the Qinling No. 1 protection station and sent four people to guard the seven birds. These guardians worked day and night. In the daytime, they observed and recorded the birds’ habits and conditions; at night, the main job was to keep them safe.
In 1990, the Shaanxi Crested Ibis Rescue and Breeding Center was set up. At the center, crested Ibises are
artificially bred（人工饲养）and can receive timely treatment when they are sick or hurt. Over the next 30 years, they also explored and created a complete system of artificial breeding techniques, laying a foundation for the birds’ later reintroduction into the wild.
“China’s protection of crested ibises is a paragon（典范）in the world’s history of preserving endangered wildlife,” Zhang told China Daily.
27．What do we know about crested ibises
A．They were faced with extinction in the 1960s.
B．They only live in China.
C．They can live for 60 million years.

（21-22八年级下·广东广州·期末） Chu Wenwen, 27, is famous as the “Beaver Princess”. Four years ago, she finished college and went back home to Xinjiang. That’s when Mengxin beavers(蒙新河狸)became a part of her life.
Mengxin beavers are a first-class state-protected animal in China. They are only found along the Ulungur River in Xinjiang. When Chu went there, she was shocked by what she saw. “Many beavers die fighting for a habitat(栖息地). Willow shrubs(灌木柳)are their most important food source, but they were disappearing in the area,” she said. “I decided to do something.”
In 2018, Chu started the “beaver canteen” program and made a plan to plant shrubs for the beavers. It might cost more than 2 million yuan. To raise money, she posted videos on the Internet, showing how beavers build dams and how she saved wild animals. She also livestreamed(直播)to show the beavers eating the shrubs she planted. Through her work, about 400,000 willow shrubs were planted with money from Internet users.
Because of Chu’s efforts, the number of beaver nests(窝)has increased from 162 to 190 over the past four years. Chu said, “We will continue to encourage more people, especially the youth, to take part in nature conservation.”
Now, she is working on a new program called the “beaver ark”. It’s a hospital for injured wild animals. She also runs a “beaver guardian” program. It trains local people to patrol(巡护)along the river.

（22-23八年级下·广东深圳·期中）Once there were many thousands of Gourma Desert （沙漠）elephants in Mali, a country in West Africa. Now, there are fewer than four hundred.
Why did the number of the elephants drop so quickly On the one hand, the elephant’s main lake, their only water source, dried up. On the other hand, the land which the elephants lived on was overused by humans.
To protect the elephants’ living environment, the Mali Elephant Project（MEP） was started in 2007. MEP met with local people and helped them make rules of using land and water. As a result, the situation became better and there was more food, forest and grassland.
However, from 2012 to 2016, poaching（偷猎）and illegal trade in the elephants increased rapidly. Eighty-three elephants were lost in 2015 alone and another fifty-one elephants were killed in 2016. “If this situation goes on, all the Gourma elephants will be killed by 2020,” said a member of MEP.
Luckily, the voice of MEP was heard. More organizations have joined together to educate the local people that trading elephants is against the law. Elephant poaching has dropped to a very low level. The local people have learned to live peacefully with the elephants, one of the wildlife treasures in the world.
1．Why was MEP started

（22-23八年级上·广东深圳·期中）Chinese scientists have discovered a new kind of dinosaur that lived 200 million years ago in what is today Southwest China’s Yunnan Province. The scientists plan to carry out further research into how the dinosaur moved and its family relationships.
Some fossils of the dinosaur were found several years ago in Yuxi, Yunnan Province, but they were not enough to make sure what kind of dinosaurs they are. However, the recent discovery has provided enough fossil materials to identify it as Asia’s earliest known thyreophoran dinosaurs(覆盾甲龙) for the first time.
The research team at the School of Life Sciences in Yunnan University has their research printed in the magazine e-Life. “It is such a meaningful discovery that our team can’t wait to have a deep research on it. The newly found dinosaur will be good for our study of the living environment after disappearance of some creatures from 250 million BC to 200 million BC,” said Xu Xing, one of the researchers.
According to the study, the dinosaur was about 3 meters long with four legs. At the same time, it could use its two front legs to catch the leaves of plants when needed. Recent study has shown that this dinosaur’s group spread rapidly, reaching all around the world within 10,000 years. Besides, the fossils provide evidence(证据) for how the different parts of the Earth moved at that time.
The team plans to take some parts from the fossil to study how the dinosaur grew and to build a 3D model to study how it moved. “The current fossil is still not fully complete. After we fill in the missing pieces, we can also make a 3D printed model for public education. Yunnan is the kingdom of dinosaurs, so we believe that other unnamed dinosaurs will also be discovered in this place” said Xu.
6．When did the newly found dinosaur lived
A．10,000 years ago. B．200 million years ago.
C．250 million years ago. D．20,000 years ago.
7．What does the discovery bring to the researchers
A．Some ffossils found in Yunnan University.
B．Some reasons for the disappearance of dinosaurs.
C．A chance to learn the future environment.
D．A record as the earliest known thyreophoran dinosaurs in Asia.
8．Which of the following statement is true
A．Some fossils of the dinosaur were found in Hunan Province.
B．The research team has their research printed in the magazine e-Life.
C．According to the study, the dinosaur was about 30 meters long with four legs.
D．This dinosaur’s group reached all around the world within 100,000 years.
9．What can we learn from the last paragraph
A．They team will make a 3D film about the dinosaur.

（22-23八年级下·广东广州·期末）An endangered species is a group of animals that could soon die out. Many species could disappear very soon if we don’t do anything to save them. There are many reasons why species become endangered but most of them are because of humans. However, there are things that we can do to save endangered species.
Habitat（栖息地）destruction is the main reason why animals become endangered. When humans move into a new area, the animals’ habitat is destroyed and there is nothing to eat because humans cut down trees and build houses and farms.
Endangered species are also the result of overhunting and overfishing. Some seal species are endangered because they are killed for their fur to make coats. Tigers are shot to make medicine and crocodiles are caught to make bags and shoes. Other animals are killed for their fur, bones or skin, or just for sports. Overfishing means that large sea animals like whales and sharks have all become endangered species, because too many are caught to make things like shark’s fin soup.
So what can people and governments do to protect animals and stop species from becoming endangered We should not pollute natural areas, and the public can help by not buying any products that are made from animals’ body parts, such as seal fur coats or crocodile bags. Governments can help, too, by making it against the law to hunt, fish, buy or sell endangered species. They can also provide money for nature reserves and zoos. If we all work together by taking these steps, we will protect our planet so that our children and their children can keep
living in harmony with other creatures, too.
11．What is the writing purpose of this passage
A．To call for actions to save endangered animals. B．To explain why animals are endangered.

B．Governments can hardly help stop species from becoming endangered.
C．Some seal species are killed to make medicine.
D．Human activities are the main reason why animals are endangered.

（21-22八年级下·广东广州·期末）
Dinosaurs weren’t the only animals that lived millions of years ago. Other creatures also lived on Earth. But then a huge planet hit the Earth. Dust from the explosion(爆炸) filled the air, forming cold and dark environment for living things for a long time. Green plants died, so animals could not find food. Most of the dinosaurs died out, but some fish and birds were still alive. One of them was a large fish called a sturgeon.
Most sturgeons live in rivers and lakes. They are bottom-feeders. They eat small living things that live in the sand and earth. Even in the very cold weather, sturgeons can find food. In this way, they have lived on for millions of years.
The past 100 years have brought a new challenge for these fish. People around the world like to eat delicious eggs of some fish. These eggs are called caviar. The most popular kind of caviar is sturgeon eggs. Since people ate millions of sturgeon eggs, few babies were born.
By the 1990s, sturgeons almost disappeared. New laws stopped overfishing and controlled the selling of caviar. Protections like these help sturgeon’s population grow again, but it will take a long time. These ancient fish have been around millions of years. ________

（22-23八年级上·广东广州·阶段练习）Monarch butterflies from eastern Canada make the most amazing journey in the insect world. Each year, this butterfly travels about 3000 miles to its winter home in central Mexico. How can it fly so far And why does it make this long and dangerous trip Scientists still don’t have an answer.
For many years, people in Mexico wondered where the orange-and-black butterflies came from every winter. Then, in 1937, a scientist started to follow and study the butterflies. For the next 20 years, he discovered that one butterfly started its journey in Canada. Four months later, it arrived in Mexico.
The length of the butterflies find their way back to the same place Another amazing thing is that the butterflies always return to the same area in central Mexico.
How do the butterflies find their way back to the same place This is an interesting question because only every fourth generation（代）makes the trip south. In other words, the butterfly that travels to Mexico this year is the great-great-grandchild of the butterfly that traveled there last year.
Each year, four generations of a Monarch butterfly family are born. Each generation of the family has a very different life. The first generation is born in the south in late April. It slowly moves north, reproduces（繁衍）, and then dies. On the trip north, two more generations are born, reproduce, and die. Each of these generations of butterflies is born. This generation has a much longer life. It lives for about eight months. This generation of butterflies makes the amazing journey back to the winter home of its great-great-grandparents. The butterflies spend the winter there, and in the spring they reproduce and then die. Their offspring will be the first generation of the next circle of life.
Today, people are still studying the Monarch butterfly. But they are not clear about everything.
19．The best title of the passage can be ________.
A．Family of Monarch butterflies B．Mystery of Monarch butterflies
C．Monarch butterflies’ birthplace D．Monarch butterflies’ winter home
20．We know that the ________ generation of Monarch butterflies travel back to central Mexico.

（21-22八年级下·广东广州·期中）Believed to have existed for more than 60 million years, crested ibises（朱鹮）are one of the oldest species of bird on Earth. Due to pollution and other human activities, the birds began to disappear in the 1960s.
In 1981, seven crested ibises were found in Yangxian county in Hanzhong, Shaanxi province. They were believed to be the last remaining ones worldwide.
But now, they have been saved from extinction（灭绝）. May 23 marked the 40th anniversary of the rediscovery of the crested ibis. Researchers said that the number has risen to more than 5,000 worldwide. There are 3,000 crested ibises in Yangxian county alone.
The bird’s survival owes to China’s early protection efforts, according to Zhang Yueming, an expert who helps protect the birds in Yangxian.
On the fourth day after the discovery of the seven crested ibises, the local government put out a series of notices to protect crested ibises. For example, hunting, cutting down trees, setting off explosives（爆炸物）in the mountains, or using fertilizers（肥料）in the birds’ natural habitat are banned.
Later, it also set up the Qinling No. 1 protection station and sent four people to guard the seven birds. These guardians worked day and night. In the daytime, they observed and recorded the birds’ habits and conditions; at night, the main job was to keep them safe.
In 1990, the Shaanxi Crested Ibis Rescue and Breeding Center was set up. At the center, crested Ibises are
artificially bred（人工饲养）and can receive timely treatment when they are sick or hurt. Over the next 30 years, they also explored and created a complete system of artificial breeding techniques, laying a foundation for the birds’ later reintroduction into the wild.
“China’s protection of crested ibises is a paragon（典范）in the world’s history of preserving endangered wildlife,” Zhang told China Daily.
27．What do we know about crested ibises
A．They were faced with extinction in the 1960s.

（21-22八年级下·广东广州·期末） Chu Wenwen, 27, is famous as the “Beaver Princess”. Four years ago, she finished college and went back home to Xinjiang. That’s when Mengxin beavers(蒙新河狸)became a part of her life.
Mengxin beavers are a first-class state-protected animal in China. They are only found along the Ulungur River in Xinjiang. When Chu went there, she was shocked by what she saw. “Many beavers die fighting for a habitat(栖息地). Willow shrubs(灌木柳)are their most important food source, but they were disappearing in the area,” she said. “I decided to do something.”
In 2018, Chu started the “beaver canteen” program and made a plan to plant shrubs for the beavers. It might cost more than 2 million yuan. To raise money, she posted videos on the Internet, showing how beavers build dams and how she saved wild animals. She also livestreamed(直播)to show the beavers eating the shrubs she planted. Through her work, about 400,000 willow shrubs were planted with money from Internet users.
Because of Chu’s efforts, the number of beaver nests(窝)has increased from 162 to 190 over the past four years. Chu said, “We will continue to encourage more people, especially the youth, to take part in nature conservation.”
Now, she is working on a new program called the “beaver ark”. It’s a hospital for injured wild animals. She also runs a “beaver guardian” program. It trains local people to patrol(巡护)along the river.
