1 . Vicky Barlow is a volunteer for a non-profit environmental organization. She was overturning stones in a rock pool in Falmouth, England when something “extremely bright and unusual” caught her eye. Under a large seaweed-covered rock, she made a very rare find: a rainbow sea slug (蛞蝓).

Rainbow sea slugs are very uncommon in England — they’re usually found in warmer waters, such as those along the west coasts of Spain, Portugal and France. In fact, there have only been three previously documented sightings of the species in the UK. But those were all found by divers rather than rock poolers. “It’s a warm-water species but it looks as if it has arrived here,” said the sea biologist Ben Holt. He adds that waters around the UK have seen rapid warming due to climate change. By the end of the century, water temperatures in the UK will rise by more than 3℃.

Sea slugs are particularly useful in related research. Most sea slugs only live up to about one year, which means they can make a very quick response to the changes in water temperatures caused by climate issues. In Australia, climate scientists have been collecting information on sea slugs for over 10 years to record the species and learn about changes in their distribution (分布), including their arrival in historically cooler waters.

Around 3,000 species of sea slugs exist in waters worldwide. They mainly feed on seaweed and other sea slugs. Unlike snails, adult sea slugs don’t have shells to protect them from being eaten by hungry marine animals. Instead, many of them have formed bright colors to scare off their enemies such as sea turtles, starfish and crabs. Some species may even have the unusual ability to steal stinging cells (刺细胞) from animals they feed on and shoot them out when threatened.

Before sending it back where it came from, Barlow placed the sea slug in a pot to get a better look at its colors. “It is absolutely amazing that I could find it on our rocky coasts,” Barlow writes in her blog. “It’s a perfect example of the incredible wildlife we have on our doorstep.”

2 . In Denmark, bicycling is one of the primary forms of transportation. In sunshine, rain and snow, you will see cyclists on their way to work, to the grocery store, or to social events. The bike is a Dane’s best friend.

Danish cycling culture is as old as the bicycle itself. Bikes were first introduced to the country in the 1880s, and during the 1920s and 1930s, the bicycle became a widespread symbol of equality and freedom. People of all social classes began biking side by side — in the cities on their way to work and in the countryside on their days off.

The increased prosperity of the late 1950s saw some Danes replacing bikes with motorcycles and automobiles. Just like their colleagues around the world, Danish urban planners believed the future belonged to cars, trucks, and ever-wider highways. In the early 1970s, however, the Mideast oil crisis terminated that development. “Car Free Sundays” were introduced in Copenhagen, and protests demanding Copenhagen to become car-free took place. Over time, concerns about air pollution, climate change, and the need for people to get enough exercise have helped bicycles make a big comeback. Denmark’s heavy taxes on petrol and automobiles are a factor, too.

Today, cycling is an inseparable part of Danish culture. Newcomers who do not know how to cycle are encouraged to learn as soon as they arrive. Danish children usually learn to bike before they begin school at the age of six — and often much earlier. In school, children learn about traffic rules, road safety, and the importance of wearing a helmet as well as good cycling habits. Another alternative for families with children is the cargo bike — a sort of oversized tricycle with a large wooden box on the front. It’s estimated that a quarter of all Copenhagen families with two or more children own one of these cargo bikes for transporting kids, groceries, and other necessities. Danish cargo bikes have also won design awards and become a Danish export success.

Commuting by bike is the fastest, easiest and most environmentally friendly way to get around the cities of Denmark. And the numbers speak for themselves: Residents who cycle in Copenhagen request 1.1 million fewer sick days. Cyclists reduce CO2 emissions by 20, 000 tonnes a year on average.

1. What led to the popularity of bicycles in Denmark during the 1920s and 1930s?

3 . The maleo (塚雉), a bird with black feathers and a pink chest, is native to Indonesia’s Sulawesi island and a few neighboring ones. The International Union for Conservation of Nature (IUCN), which identifies wildlife across the world currently facing threats, estimates only 800 to 1,400 adult maleos remain in the wild. Experts do not know how many maleos still live across West Sulawesi island. They were only able to record the presence of nesting grounds in 23 villages based on reports from locals in the area. But of those, only 18 are considered active nesting areas.

Recently, the birds have been faced with new threats, which accelerate their decline. The Indonesian government plans to move the nation’s capital from Jakarta to a new city on Borneo island, which is just a six-hour boat trip apart from Sulawesi island. The island takes on the building of new roads and seaports to be used to transport materials to the new capital. Activities also include tree clearing, digging, and removing stones. The process already has changed the forest environment on West Sulawesi and is harming maleo nesting areas near the beach. These changes have made the trip for maleos to lay their eggs increasingly difficult.

Another problem has been poachers. The Associated Press reports that, regardless of official ban, they steal maleo eggs that the males’ parents have hidden in the sand, and sell the eggs for about $1 to people as food. The eggs are a traditional gift for many people in Mamuju and other parts of Sulawesi.

“As far as I know, maleo birds are in decline,” said Andi Aco Takdir, chief of the West Sulawesi Forestry Agency. He pointed to several reasons for the decline, including destruction of beach areas, and expanding human development activities. He added that government officials there are prepared to take steps to protect the maleos even with the new capital development. Andi said, “Nature conservation must be used as an achievement and must not be built leaving behind problems.”

A．People who hunt maleos for their meat.

B．People who live by selling maleo eggs.

C．People who engage in illegal hunting.

D．People who regard maleo eggs as gifts.

4. What can we infer from Andi’s words?

A．The new capital development might be stopped at once.

B．The government will balance conservation and development.

C．There seems to be a tough way for the new capital to develop.

D．The government will concentrate on solving urban problems.

4 . Falcons are powerful birds that may be trained to hunt in cooperation with humans. The art of training falcons as “hunting dogs of the skies” is called falconry (训鹰术). It was developed in the ancient Arabian Desert around 4000 B. C. In the past, falconry mainly involved hunting with falcons to supplement one’s diet. But now, it has become the favorite sport and pastime in the Arabian Peninsula.

Falconry includes three major processes: acquiring the falcons, training them, and hunting with them. Every year, falconers begin capturing wild falcons in June and July, the migration season. The best birds to catch are the ones with naturally nurtured hunting skills, aged one or two years. Once the falcons are captured, their heads are immediately covered with a leather hood. This is essential because they imprint as their master whomever they see first after the hood is removed. Right after a bird is caught, the training process starts. It begins by depriving (剥夺) the bird of food to make it easier to tame. The birds are taught to know their own name and respond to their master when called. Arab falconers live with their birds day and night in order to build a strong relationship with them.

By the end of October or mid-November, the trained falcons are ready to hunt in the desert. They have excellent vision, 2. 6 times greater than that of a human. They are also the fastest divers on the planet. One hunting technique that sets them apart from other animals is that they can be trained to deliver their prey, without killing it first. This is vital in Islamic culture because animals used for food must still be alive to ensure that the meat is halal, that is, properly prepared according to Islamic law.

Falcons have played such a crucial role in traditional Islamic cultures that a number of countries in the Middle East have made them their national bird. Falconry has grown so popular that specialist hospitals have been established to take care of these magnificent birds. Falcons are even issued their own passports. They are the only animals in the United Arab Emirates that are legally allowed to travel inside planes, enjoying a level of luxury that some humans can only dream of.

5 . American researchers say they have developed a method to remove carbon dioxide (CO₂) from the sea. The researchers say the process can be an additional way to help reduce CO₂ from the environment to fight the effects of climate change.

Plants and currents in the ocean absorb large amounts of CO₂ from the atmosphere. The sea is estimated to have drawn in about 30 percent of carbon emissions since the Industrial Revolution. But carbon emissions also make oceans more acidic (酸性的). It can hurt coral reefs, which are sensitive to ocean acidity. Reef damage then do damage to the growth of many kinds of sea life.

Gaurav Sant, director of UCLA’s Institute for Carbon Management, said the technology is meant to use the ocean’s natural abilities to reduce carbon levels in the sea. The process sends an electrical charge through seawater flowing through tanks on a large boat. That sets off a series of chemical reactions that turn the carbon emissions into a solid mineral that includes calcium carbonate (碳酸钙). The seawater then returned to the ocean and can pull more carbon dioxide out of the air. The calcium carbonate settles to the sea floor.

The process has already been demonstrated in California. Researchers are working on plans to launch another project in Singapore. The two projects are expected to be fully operational by 2025. Researchers say they are expected to remove thousands of tons of CO₂ per year. If successful, the plan is to build additional centers to remove millions of tons of carbon each year.

But experts say even if that amount of carbon can be removed, that is still thousands of times less than what will be needed to effectively reduce climate change. Margaret Leinen, director of an ocean research center, said, “While the process will likely be effective, I question how much effect it will have on climate change over a long period.” Sant said the success of such technology will greatly rely on “how fast you can build the centers”.

6 . Humans can make do with scarves, coats and gloves in cold weather. Some animals can hibernate (冬眠) for the winter. A new study finds that reptiles (爬行动物) and birds do something that is similar to hibernation, but a little different. In very cold weather, their body temperatures greatly drop into an energy-saving state in order to survive. The ability to thermoregulation (体温调节) for reptiles and birds is possible.

In Texas, where the city of Beaumont reached a low of 18 degrees Fahrenheit last month, it looked as if alligators (短吻鳄) had died of cold — yet alive in iced-over water. By ensuring their long noses stayed above the water line, the cold-blooded creatures were able to lower their body temperatures to survive the sudden short period of very cold weather. The process, in the case of cold-blooded animals like reptiles, is called brumation — it’s like a short state of hibernating. While in this state, reptiles become sleepy and they can go for a long time without eating or drinking. For example, alligators can be in brumation from just a few hours to months.

Like reptiles and mammals, birds can go into a state called torpor in order to save energy under very cold conditions. “Torpor is somewhere between a short sleep and hibernation,” said Justin Baldwin, a PhD candidate in biology at Washington University in St. Louis. Baldwin studied 29 species of hummingbirds living in Colombia. Researchers found that hummingbirds can enter into deep or shallow torpor, depending on several factors, including their size and weather conditions. In deep torpor, the birds are much more likely to be affected by disease. And what’s more, they would be easily harmed by their enemies.

Some bird lovers want to help the birds when they are in torpor. For example, the Bird Alliance of Oregon offers a few tips on how to keep the birds from danger.

From then on, the two were _________. Every bit of love Renae gave, the little dog returned more. “She was such a sweet dog,” Renae says. “She’d lick your face forever if you didn’t stop her.”

When Renae was 14, her father got a new job and the house needed to be free of noise. “Chloe liked barking,” Renae says. “I didn’t want to lose my dog but I didn’t have any _________ as a kid.” With no easier _________, the family sent Chloe to a humane society(动物保护协会). Though they were _________ that the dog would find a new home with people who loved her, they couldn’t know for sure. “I called the humane society to try to _________ what happened to her, but they couldn’t tell me anything. So, I never knew,” Renae says _________.

Later, Renae grew up, got married, and had a child. But her family didn’t feel quite _________. Remembering the joy that having a dog had brought her as a kid, Renae wanted her daughter to __________ the same. She had it in her mind that she would __________ a puppy. One day she saw a post on Facebook about a senior dog that needed a new home. The dog in the photograph looked like Chloe-she was even named Chloe. In an __________ it was decided: she would adopt it. “When we met, she ran up to me and started __________ my face. I was crying,” Renae says. “I just knew in my heart that it was her.” After years of thinking she’d never see her dog again, Renae is __________ to have her back. “I get so excited to come home and see her,” she says. “__________ Chloe, she’s made herself right at home,” Renae says. “And why shouldn’t she?

8 . Sleep is a necessary biological(生物的)function that has long interested scientists.

As we all know, most animals sleep. Scientists have studied everything from mice to fruit flies in the lab to get a better understanding of what happens when animals sleep—and why so many do it. However, gathering data on how animals sleep in their natural habitat has always been tricky and hard to do.

But scientists did just that with wild chinstrap penguins(帽带企鹅)in Antarctica. In doing so, researchers found birds in the nesting colony took over 10,000 microsleeps throughout the day-amounting to 1l hours of sleep. The microsleep last only seconds. Researchers think that microsleeps might help the animals avoid enemies that might be more likely to strike if the penguins are asleep for longer—especially when one parent goes out feeding in the ocean for days, leaving the other parent to protect the eggs.

Vladyslav Vyazovskiy, a sleep scientist who was not involved in the study, is excited about this new data. “Most of what we know about the fundamental biology of sleep was obtained in laboratory conditions, which were completely different from conditions where sleep evolved. Context matters,” says Vyazovskiy.

Microsleeps are much shorter than the minutes-long micronaps that have been shown to benefit humans. And study co-author Paul-Antoine Libourel is careful to not mix this insight about the success of microsleeps in penguins with that in humans. “This is not related to human physiology, and won’t tell us more about the function of human sleep.”

To study the penguins, scientists implanted devices into a small group of penguins’ brain and neck muscles. These brainwave and location data coupled with filming these birds in the nest gave sleep data about them. But the equipment had never been used before, so this data collection was only supposed to be a test.

The study is an early insight into a relatively large amount of scientific knowledge about sleep. “Pretty much every study on sleeping birds discovers something new, something we didn’t know before,” says Libourel.

D．Scientists show interest in animals’ sleep quality

9 . One Saturday in June, I got off the train from Vienna at Altenberg station, in the midst of a gathering of bathers, such as often flock to our village at fine weekends.

I had gone only a few steps along the street and the crowd had not yet scattered when, high above me in the air, I saw a bird whose species I could not at first determine. It flew with slow, measured wing-beats, varied at set intervals by longer periods of gliding. It seemed too heavy to be a hawk; for a stork (鹳), it was not big enough and, even at that height, neck and feet should have been visible. Then the bird made a sudden turn so that the setting sun shone for a second full on the underside of the great wings which lit up like stars in the blue of the skies. The bird was white. By Heaven, it was my cockatoo (凤头鹦鹉)! The steady movements of his wings clearly indicated that he was setting out on a long-distance flight.

“What should I do? Should I call to the bird?” Well, have you ever heard the flight-call of the greater cockatoo? No? But you have probably heard pig-killing in the traditional method. Imagine the loudest long cry a pig could make, picked up by a microphone and amplified many times over by a powerful speaker. A man can imitate it quite successfully, though somewhat weak, by shouting at the top of his voice “O-ah”. I had already proved that the cockatoo understood this imitation and promptly “came to heel”. But would it work at such a height? A bird always has great difficulty in making the decision to fly downwards at a steep angle. To yell, or not to yell, that was the question. If I yelled and the bird came down, all would be well, but what if it sailed calmly on through the clouds? How would I then explain my song to the crowd of people?

Finally, I did yell. The people around me stood still, rooted to the spot. The bird hesitated for a moment on outstretched wings, and then, folding them, it descended in one dive and landed upon my outstretched arm. Once again I was master of the situation.

1. What was the author’s cockatoo like?

A．It looked like a hawk.	B．It was blue and shiny.
C．Its neck and feet were long.	D．It was white with great wings.

2. How did the author signal to his cockatoo?

3. What does the underlined part “came to heel” in paragraph 3 mean?

A．Flew about.

B．Came back.

C．Came around.

D．Landed on the ground.

4. Which can be inferred about the author from the text?

A．He knew birds very well.	B．He could speak with his bird.
C．He liked showing off in public.	D．He often surprised people around him.

10 . Dog ownership may be associated with longer life, especially for heart attack and stroke (中风) suvivors who live alone, according to a new study.

Previous studies have shown that dog ownership alleviates social isolation (隔绝), improve physical activity and social bonds, even lowers blood pressure, leading researchers to believe dog owners could potentially have better health outcomes compared to non-owners. They sought to determine how dog ownership affected health outcomes.

Researchers compared the health outcomes of dog owners and non-owners after a heart attack or stroke using health data provided by the Swedish National Patient Register. Patients in the study were Swedish residents aged 40 to 85 who experienced a heart attack or stroke. Compared to people who did not own a dog, researchers found that for dog owners, the risk of death for heart attack patients living alone after hospitalization (住院) was 33% lower and 15% lower for those living with a partner or child. The risk of death for stroke patients living alone after hospitalization was 27% lower and 12% lower for those living with a partner or child.

The lower risk of death associated with dog ownership could be explained by an increase in physical activity and decreased depression and loneliness, both of which have been connected to dog ownership in previous studies.

While this study drew the conclusion from a large sample (样本), potential misclassifications (错误分类) of dog ownershipin couples living together, death of a dog and change of ownership could have affected the outcomes of the study.

The results of this study suggest positive effects of dog ownership for patients who have experienced a heart attack or stroke. However, more research is needed to confirm a cause-effect relationship. Moreover, from an animal welfare perspective (角度), dogs should only be owned by people who feel they have the ability and knowledge to give the pet a good life.
