The Woolly Monkey Mysteries：The Quest to Save a Rain Forest Species
By Sandra Markle.Ages 8 to 10.
Woolly Monkeys spend most of their time high up in 150 foot tall trees.That makes them difficult animals to count and to study.But cameras have provided valuable information and taken, as this book shows, amazing pictures.Experts now believe that Peru's lowland monkeys and the waste they produce are necessary to the survival of the rain forest.
Camp Panda：Helping Cubs Return to the Wild
By Catherine Thimmesh.Ages 10 to 12.
The giant panda is much beloved in China, but in the past 40 years, at least half of its habitat has been destroyed.Camp Panda tells about efforts to reintroduce the giant pandas into the wild so that they might have a future.As part of the efforts, people wear panda costumes that smell like pandas while weighing and measuring the young pandas.They aren't supposed to get used to seeing and being around people, because people could pose a threat to them in the wild.
Beyond Words：What Elephants and Whales Think and Feel
By Carl Safina.Ages 10 and older.
Carl Safina studied elephants in an African national park and killer whales off the coast of Washington state.He learned about their strong family bonds, the surprising ways they communicate and how they play and hang out with one another.This book makes a strong case for protecting the ability of these animals to live freely.
Back from the Brink：Saving Animals from Extinction

Say the phrase “female environmental pioneers”， and among the names you will hear are Rachel Carson who wrote pesticides, chimpanzee expert Jane Goodall, and 17 year old climate change activist Greta Thunberg. To mark Women's History Month, KidsPost is sharing the story of an environmental pioneer who is not that famous but equally remarkable.
At age 3, Sylvia Earle found her lifelong passion while playing on a beach.A wave suddenly came up and knocked her over.
“My mother ...saw the big smile on my face and let me run back in，” Earle told a TV interviewer years later. “And I've been running back in ever since.”
Earle is now 84 years old and has spent a lifetime exploring the world's oceans and working to protect them from pollution, overfishing and other threats.
She is a pioneer in using scuba gear. Scuba gear lets divers take breath underwater.She holds the world record for the deepest untethered walk on the ocean floor at 1,250 feet.This means she was not tied to anything when she was walking underwater.During this exploration, she planted a US flag.
In 1998, Time magazine gave Earle its first Heroes for the Planet award.She was the first female chief scientist at the National Oceanic and Atmospheric Administration (NOAA)．It is the US ocean and atmosphere group. She was also elected to the National Women's Hall of Fame.
Earle has spent her life teaching people about the ocean.She notes how much it affects the weather, and what we eat and drink.She has something to say to those who don't understand why the ocean matters.“They should know that with every breath they take, every drop of water they drink, the ocean is touching them，” Earle says.“You should treat the ocean as if your life depends on it — because it does.”
4．What does Earle's lifelong passion refer to
A．Teaching people how to dive.
B．Writing articles for magazines.
C．Exploring and protecting oceans.
D．Providing equipment for divers.
5．What do we know about Earle from the text
A．Earle is a world record holder.
B．Earle's mother is in support of her work.
C．Earle is a remarkable British ocean explorer.
D．Earle is the only female chief scientist at NOAA.
6．Which of the following words can best describe Earle
A．Brave and conservative.
B．Devoted and courageous.
C．Determined and rigid.
D．Ambitious and modest.
7．Which of the following statements will Earle agree with according to the text
A．People should stop overfishing and eating seafood.
B．The ocean plays a significant role in human's life.
C．The weather has a far reaching effect on the ocean.
D．The exploration of the ocean can be done without limit.
C
Coral reefs (珊瑚礁) are an integral part of sea life and sustain it by providing shelter and habitat to various organisms.They also supply and recycle nutrients as well as enable a growing fish population, along with other species, for a healthy and diverse ecosystem. However, the rise in average water temperatures due to climate change has resulted in more frequent and long time “coral bleaching (珊瑚白化)” events that damage their health, causing fish and other sea species to abandon them.
In order to restore this delicate ecosystem, scientists from the UK and Australia conducted a study that involved using loudspeakers underwater near damaged coral reefs to make them sound healthy and attract fish, potentially kick starting the natural recovery process of coral reefs and their dependent life forms.The location for this experiment was the Great Barrier Reef in the Coral Sea, found alongside the east coast of Queensland, Australia. The site is noted to have the largest coral reef system in the world.
“Healthy coral reefs are remarkably noisy places — the crackle of snapping shrimp (鼓虾) and the whoops and grunts of fish.Young fish concentrate on these sounds when they're looking for a place to settle，” said Steve Simpson, study co author and a professor at the University of Exeter, UK.
By using loudspeakers to copy such sounds, parts of dead coral reefs were found to attract twice as many fish, compared to places where no sounds were played.“These returning fish are crucial for coral reefs to function as healthy ecosystems.Boosting fish population in this way could help to kick start natural recovery processes, preventing the damage we're seeing on many coral reefs around the world，” said lead author, Tim Gordon.
8．What causes the phenomenon of coral bleaching
A．Diverse species.
B．Noise pollution.
C．Fishing industry.
D．Climbing temperatures.
9．What approach is introduced to recover the coral reefs
A．Removing damaged coral reefs.
B．Using loudspeakers to keep fish away.
C．Building new homes for sea species.
D．Playing certain sounds to attract fish.
10．Why are Steve Simpson's words quoted
A．To provide some findings of the study.
B．To show the progress of the experiment.
C．To explain reasons for the new approach.
D．To give another solution to the problem.
11．What can we infer from the last paragraph
A．The attempts are in vain.
B．Natural recovery is impossible.
C．Initial success has been achieved.
D．The coral reefs have returned to normal.
D
For centuries, fishers in Narrangansett have fished in the waters of the northwestern Atlantic for herrings (鲱鱼)．But as climate change warms the world's seas, the herrings are disappearing at the southern end of their range and turning up more often at its northern edges.A study shows that concentrations of marine species populations have been shifting away from the equator and toward the poles during the course of the past century.These movements could wreak_havoc_on food webs and endanger the livelihoods (生计) of fishers.
The tropical water at the equator is well known for having the richest diversity of marine life on Earth.The number of marine species naturally decreases gradually as you head towards the poles.Ecologists have assumed this global pattern has remained stable over recent centuries until now. Our recent study found the ocean around the equator has already become too hot for many species to survive, and that global warming is responsible.And as species flee to cooler water towards the poles, it's likely to have deep impacts on marine ecosystems.
Losing species in tropical ecosystems means ecological adaptation to environmental changes is reduced, potentially damage ecosystem persistence.In subtropical ecosystems, species richness is increasing. This means there'll be species invaders, and new competitive relationships. This could result in ecosystem collapse in which species go extinct and ecosystem services (such as food supplies) are permanently changed.
One way is to reduce our emissions aggressively.Other opportunities could also help safeguard biodiversity and hopefully minimize the worst impacts of it shifting away from the equator.Designing climate smart reserves could further protect biodiversity from future changes.For example, reserves for marine life could be placed where the climate will be stable over the foreseeable future.We should take action without delay.
12．What does the underlined phrase “wreak havoc on” probably mean in paragraph 1
A．Clarify. B．Classify.
C．Destroy. D．Purify.
13．What can be learnt from the second paragraph
A．Some species move to water in lower temperature.
B．More marine species exist at the poles than the equator.
C．The subtropical water has the most diverse marine species.
D．The global pattern of the ecosystem remains unchanged now.
14．What is the main idea of the third paragraph
A．The increase of species in subtropical ecosystem.
B．The decline of ecological changes in the ocean.
C．The temporary changes in ecosystem services.
D．The effects of species' immigration on marine ecosystem.
15．What is the writer's purpose in writing this article
A．To inform readers of the reduction of marine species.
B．To appeal to readers to protect marine biodiversity.
C．To predict the future of the marine ecosystem.
D．To explain the reasons for global warming.

第一节 参考范文：
Dear students，
With the aim of protecting the environment, we have launched an activity on the theme of “Green Earth, Start from Me”．
As the saying goes, “from little things, big things grow.” Some simple acts do make a difference.Firstly, you're supposed to save electricity by turning off the electric devices once you stop using them. Secondly, give away your old things such as textbooks that are still in good condition for reuse. Last but not least, you can sort out the garbage so that it can be dealt with more effectively.
Every bit counts.Let's join hands and take immediate action from now on.
The Students' Union
第二节 参考范文：
It wasn't long before the dogs were sleeping in the house and assuming their role as “watchdogs”. They became fierce protectors of our home, a comforting presence.Each day, they would police the property wholeheartedly and then return to the house expecting a sweet treat and a gentle pat on the head for a job well done.Their love and devotion were unquestionable.They quickly became integrated into our daily lives.Where did they come from That was a question I never stopped asking myself.Maybe an unavoidable tragedy brought the “little wolves” to us, or maybe they had been adopted by a misguided human.Whatever it was, our furry friends are the essence of happiness.They display absolute joy in simply being alive.Their wagging tails and cute little noses always lift my spirits.
Time in the yard feels like a second childhood with Daisy and Emma playing about our feet.Filled with so much energy, they race around the yard, barking and chasing each other, and then run back to us for another love session of pat and hugs.When my wife goes shopping, she comes home to find the dogs waiting patiently in the driveway, resting on a nest of her shoes.Those who rescue abandoned animals are the best people in the world.Diana is one of them.She can win the hearts of two wild animals with love and kindness.The “little wolves” are now so important in our lives that we can't imagine being without them.The dogs have taught us to cherish every moment spent in their company.I've also learned that it's highly possible to turn a cat lady into a dog lady with two “little wolves” and a whole lot of love.

Say the phrase “female environmental pioneers”， and among the names you will hear are Rachel Carson who wrote pesticides, chimpanzee expert Jane Goodall, and 17 year old climate change activist Greta Thunberg. To mark Women's History Month, KidsPost is sharing the story of an environmental pioneer who is not that famous but equally remarkable.
At age 3, Sylvia Earle found her lifelong passion while playing on a beach.A wave suddenly came up and knocked her over.
“My mother ...saw the big smile on my face and let me run back in，” Earle told a TV interviewer years later. “And I've been running back in ever since.”
Earle is now 84 years old and has spent a lifetime exploring the world's oceans and working to protect them from pollution, overfishing and other threats.
She is a pioneer in using scuba gear. Scuba gear lets divers take breath underwater.She holds the world record for the deepest untethered walk on the ocean floor at 1,250 feet.This means she was not tied to anything when she was walking underwater.During this exploration, she planted a US flag.
In 1998, Time magazine gave Earle its first Heroes for the Planet award.She was the first female chief scientist at the National Oceanic and Atmospheric Administration (NOAA)．It is the US ocean and atmosphere group. She was also elected to the National Women's Hall of Fame.
Earle has spent her life teaching people about the ocean.She notes how much it affects the weather, and what we eat and drink.She has something to say to those who don't understand why the ocean matters.“They should know that with every breath they take, every drop of water they drink, the ocean is touching them，” Earle says.“You should treat the ocean as if your life depends on it — because it does.”
4．What does Earle's lifelong passion refer to
A．Teaching people how to dive.
B．Writing articles for magazines.
C．Exploring and protecting oceans.
D．Providing equipment for divers.
5．What do we know about Earle from the text
A．Earle is a world record holder.
B．Earle's mother is in support of her work.
C．Earle is a remarkable British ocean explorer.
D．Earle is the only female chief scientist at NOAA.
6．Which of the following words can best describe Earle
A．Brave and conservative.
B．Devoted and courageous.
C．Determined and rigid.
D．Ambitious and modest.
7．Which of the following statements will Earle agree with according to the text
A．People should stop overfishing and eating seafood.
B．The ocean plays a significant role in human's life.
C．The weather has a far reaching effect on the ocean.
D．The exploration of the ocean can be done without limit.
C
Coral reefs (珊瑚礁) are an integral part of sea life and sustain it by providing shelter and habitat to various organisms.They also supply and recycle nutrients as well as enable a growing fish population, along with other species, for a healthy and diverse ecosystem. However, the rise in average water temperatures due to climate change has resulted in more frequent and long time “coral bleaching (珊瑚白化)” events that damage their health, causing fish and other sea species to abandon them.
In order to restore this delicate ecosystem, scientists from the UK and Australia conducted a study that involved using loudspeakers underwater near damaged coral reefs to make them sound healthy and attract fish, potentially kick starting the natural recovery process of coral reefs and their dependent life forms.The location for this experiment was the Great Barrier Reef in the Coral Sea, found alongside the east coast of Queensland, Australia. The site is noted to have the largest coral reef system in the world.
“Healthy coral reefs are remarkably noisy places — the crackle of snapping shrimp (鼓虾) and the whoops and grunts of fish.Young fish concentrate on these sounds when they're looking for a place to settle，” said Steve Simpson, study co author and a professor at the University of Exeter, UK.
By using loudspeakers to copy such sounds, parts of dead coral reefs were found to attract twice as many fish, compared to places where no sounds were played.“These returning fish are crucial for coral reefs to function as healthy ecosystems.Boosting fish population in this way could help to kick start natural recovery processes, preventing the damage we're seeing on many coral reefs around the world，” said lead author, Tim Gordon.
8．What causes the phenomenon of coral bleaching
A．Diverse species.
B．Noise pollution.
C．Fishing industry.
D．Climbing temperatures.
9．What approach is introduced to recover the coral reefs
A．Removing damaged coral reefs.
B．Using loudspeakers to keep fish away.
C．Building new homes for sea species.
D．Playing certain sounds to attract fish.
10．Why are Steve Simpson's words quoted
A．To provide some findings of the study.
B．To show the progress of the experiment.
C．To explain reasons for the new approach.
D．To give another solution to the problem.
11．What can we infer from the last paragraph
A．The attempts are in vain.
B．Natural recovery is impossible.
C．Initial success has been achieved.
D．The coral reefs have returned to normal.
D
For centuries, fishers in Narrangansett have fished in the waters of the northwestern Atlantic for herrings (鲱鱼)．But as climate change warms the world's seas, the herrings are disappearing at the southern end of their range and turning up more often at its northern edges.A study shows that concentrations of marine species populations have been shifting away from the equator and toward the poles during the course of the past century.These movements could wreak_havoc_on food webs and endanger the livelihoods (生计) of fishers.
The tropical water at the equator is well known for having the richest diversity of marine life on Earth.The number of marine species naturally decreases gradually as you head towards the poles.Ecologists have assumed this global pattern has remained stable over recent centuries until now. Our recent study found the ocean around the equator has already become too hot for many species to survive, and that global warming is responsible.And as species flee to cooler water towards the poles, it's likely to have deep impacts on marine ecosystems.
Losing species in tropical ecosystems means ecological adaptation to environmental changes is reduced, potentially damage ecosystem persistence.In subtropical ecosystems, species richness is increasing. This means there'll be species invaders, and new competitive relationships. This could result in ecosystem collapse in which species go extinct and ecosystem services (such as food supplies) are permanently changed.
One way is to reduce our emissions aggressively.Other opportunities could also help safeguard biodiversity and hopefully minimize the worst impacts of it shifting away from the equator.Designing climate smart reserves could further protect biodiversity from future changes.For example, reserves for marine life could be placed where the climate will be stable over the foreseeable future.We should take action without delay.
12．What does the underlined phrase “wreak havoc on” probably mean in paragraph 1
A．Clarify. B．Classify.
C．Destroy. D．Purify.
13．What can be learnt from the second paragraph
A．Some species move to water in lower temperature.
B．More marine species exist at the poles than the equator.
C．The subtropical water has the most diverse marine species.
D．The global pattern of the ecosystem remains unchanged now.
14．What is the main idea of the third paragraph
A．The increase of species in subtropical ecosystem.
B．The decline of ecological changes in the ocean.
C．The temporary changes in ecosystem services.
D．The effects of species' immigration on marine ecosystem.
15．What is the writer's purpose in writing this article
A．To inform readers of the reduction of marine species.
B．To appeal to readers to protect marine biodiversity.
C．To predict the future of the marine ecosystem.
D．To explain the reasons for global warming.

第一节 参考范文：
Dear students，
With the aim of protecting the environment, we have launched an activity on the theme of “Green Earth, Start from Me”．
As the saying goes, “from little things, big things grow.” Some simple acts do make a difference.Firstly, you're supposed to save electricity by turning off the electric devices once you stop using them. Secondly, give away your old things such as textbooks that are still in good condition for reuse. Last but not least, you can sort out the garbage so that it can be dealt with more effectively.
Every bit counts.Let's join hands and take immediate action from now on.

第二节 参考范文：
It wasn't long before the dogs were sleeping in the house and assuming their role as “watchdogs”. They became fierce protectors of our home, a comforting presence.Each day, they would police the property wholeheartedly and then return to the house expecting a sweet treat and a gentle pat on the head for a job well done.Their love and devotion were unquestionable.They quickly became integrated into our daily lives.Where did they come from That was a question I never stopped asking myself.Maybe an unavoidable tragedy brought the “little wolves” to us, or maybe they had been adopted by a misguided human.Whatever it was, our furry friends are the essence of happiness.They display absolute joy in simply being alive.Their wagging tails and cute little noses always lift my spirits.
Time in the yard feels like a second childhood with Daisy and Emma playing about our feet.Filled with so much energy, they race around the yard, barking and chasing each other, and then run back to us for another love session of pat and hugs.When my wife goes shopping, she comes home to find the dogs waiting patiently in the driveway, resting on a nest of her shoes.Those who rescue abandoned animals are the best people in the world.Diana is one of them.She can win the hearts of two wild animals with love and kindness.The “little wolves” are now so important in our lives that we can't imagine being without them.The dogs have taught us to cherish every moment spent in their company.I've also learned that it's highly possible to turn a cat lady into a dog lady with two “little wolves” and a whole lot of love.
