Across North America, hundreds of bird species are victims of the cowbird, which adds its own egg to other birds' nests, tricking another species into raising its offspring. One tar get, the yellow warbler（林莺）, has a special call to warn egg-warming females when cowbirds are approaching the area. Now, researchers have found the females act on that warning one day later—suggesting their long-term memories might be much better than thought.

“Animals are smart in the context in which they need to be smart,” says Mark Hauber, an animal behavior researcher at the University of Illinois. who co-authored the new study. He wanted to see whether yellow warblers had the capacity to remember their own important warning call known as a seet. The birds make the call only when a cowbird is near. When yellow warbler females hear it, they go back to their nests and sit tight. But it's been unclear whether they still remember the warning in the morning.

So the study team found 27 yellow warbler nests and exposed females to either silence, or one of two sounds: a recording of a seet call or a recording of a common warning—used for predators or competition-called a chip for 10 minutes. The next morning, the researchers observed the birds for 80 minutes: 20 minutes before sunrise and 60 minutes after, when the cowbirds are at their most active.

They found the warblers left their nests less often after hearing a seet call than if they had heard no warning. The chip call didn't seem to have any impact on how often they left the nest. Sixteen hours after the experiment, the birds were still behaving as if there's a cowbird threat. It allowed us to think that these kinds of signals carried long-term meaning. Of more than 200 species targeted by cowbirds, yellow warblers are the only so far known to have developed a warning call tailored to cowbirds.

1. When hearing a seet sound, female yellow warblers usually ________.

A．get ready to fight against the cowbirds	B．return to their nests to be on the lookout
C．make a similar seet sound to warn partners	D．remember their own important warning call

2. How did the researchers carry out the study?

A．By giving examples.	B．By making comparisons.
C．By listing numbers.	D．By using an expert's words.

3. What is the finding of the study?

A．Yellow warblers don't like silent surroundings.

B．Yellow warblers are sensitive to the chip sounds.

C．Yellow warblers prefer the seet sounds to the chip sounds.

D．Yellow warblers have the ability to remember certain meaningful calls.

People tend to loathe pigeons for the way they mess up parked cars or flock to food wastes on the sidewalk. But the truth is that more than 300 species of wild pigeons have been found on the earth, many of which are quite impressive.

“Pigeons are biological marvels,” says Rosemary Mosco, author of A Pocket Guide to Pigeon Watching. “They make milk for their young. They can take off almost vertically. They see colors we can’t, hear sounds we can’t, and find their way across hundreds of miles using mechanisms we don’t fully understand,” she says. “They’re the world’s most overlooked birds.”

Interestingly, both pigeons and doves are members of the Columbidae family, and while the term ‘pigeon’ tends to be applied to larger species and ‘dove’ to smaller ones, Mosco notes in her illustrated field guide that there is barely scientific or evolutionary distinction to either group.

There’s also evidence wild pigeons were a staple food source for Neanderthals, and later humans, beginning at least 67,000 years ago. What is more well known is the pigeon’s invaluable service of long-distance communication for many different civilizations, from the ancient Romans to Genghis Khan.

“For much of their history, they signified wealth and power,” says Mosco. “They were flying Ferraris.” In some parts of the world, the fastest pigeons still fetch mind-boggling sums. In 2020, a single racing pigeon named New Kim was sold for around $1.9 million in a Belgian auction (拍卖).

With pigeons everywhere we look in urban life, it may be difficult to imagine a world without pigeons. But even these adaptable birds are not immune to extinction.

1. Which word can replace “loathe” in paragraph 1?

A．Hate.	B．Chase.
C．Observe.	D．Analyze.

2. Why are pigeons called “biological marvels”?

A．They can only take off in a vertical way.

B．They can make milk for young children.

C．They have abilities beyond human’s imagination.

D．They have a tendency to be overlooked by humans.

3. What do we know about pigeons and doves?

A．Pigeons and doves have distinct origins.

B．Pigeons are used to carry large sums of money.

C．Scientifically speaking, little difference exists between them.

D．Pigeon’s service of long-distance communication isn’t valuable.

4. What might be illustrated about pigeons in the following paragraphs?

A．Pigeons in urban areas around the world.

B．Examples of how adaptable pigeons can be.

C．Basic facts about pigeons’ immune system.

D．Pigeons becoming an endangered species.

At first glance, it’s a scene that plays out daily in cities across America. A US Postal Service carrier steps out of his mail truck and goes across the street, letters in hand. That much is unremarkable. But this postman either doesn’t notice or doesn’t seem to care that a clumsy American black bear is sitting on his haunches a few yards away, vigorously scratching(挠，搔)his shedding winter coat hard.

It’s a phenomenon happening in urban areas across the United States and around the world, and it’s not unique to black bears. Coyotes (丛林狼) look before crossing a street. Black bears know when it’s trash day. Racoons figure out how to pull bungee cords (弹力绳) off trash cans.

However, a number of the city bears died during a study, with vehicle strikes the leading cause. Other studies paint a less optimistic picture. The bears in Asheville weigh more and have more cubs, but their young rarely survive, resulting in net population declines. Neither is it true that humans and bears always live in harmony—even in open-minded Asheville, the bears have killed pets and injured at least one person in recent years.

To learn how residents can safely coexist with their primitive neighbors, Strules, director of the Urban Wildlife Institute at Chicago’s Lincoln Park Zoo, is planning an experiment. Two neighborhoods will be the focus of an educational campaign, which encourages bear-conscious practices such as keeping pets tied, locking the garage, removing bird feeders, and not approaching or feeding the animals.

Strules hopes her effort will offer guidance on the best way to live with the animals—both for them and for us. “Wildlife belongs to everyone,” Strules says, “but we want to keep bears wild.”

1. What is happening according to paragraph 2?

A．Humans are teaching animals survival skills.

B．Humans and animals are living in harmony.

C．Some wild animals are fitting into city life.

D．Many species are tired of their habitats.

2. What might be the main cause of death for the city bears?

A．Food shortage.	B．Loss of habitat.
C．Gain in weight.	D．Road accidents.

3. Which statement can agree with Strules’ experiment?

A．Rome was not built in a day.	B．It is never too late to mend.
C．Bad luck always comes in threes.	D．A work ill done must be twice done.

4. Which of the following could be the best title for the text?

A．Wild Animals: Our New Neighbors

B．Protection of the Endangered Wildlife

C．Black Bears: a Dangerous Species

D．A New Landscape in Our Community

There’s nothing quite like a winter wonderland. When the snow falls and the lakes and ponds freeze over, there’s a certain magical chocolate-box feeling to the world that ironically makes us feel cozy inside. However, it might be different for some of our pets.     1    . Even those animals who don’t mind a frosty walk or a house that’s cooler than usual may need some protection from the elements for their own good. As a pet owner, you’ll undoubtedly make sure that your pets are comfortable and properly winterized.

• Keep the walks brief

    2    . If it gets cold enough for you to need a coat, know that your dog is probably also feeling the chill. Therefore, mind the length of walks when the winter is just coming.

•     3    

If your dog is shivering a lot, it isn’t a bad idea to give them a blanket or a warmer bed. Avoid electrically heated blankets and pads as some pups might not realize when it gets too hot.

• Wrap them up in the right clothes

Make sure the clothes you choose fit them properly and don’t have any dangling bits they could swallow.     4    , if your dog is truly uncomfortable putting on clothes.

• Watch out for dangerous snow

Salt and antifreeze on sidewalks are potentially deadly to pets.     5    . If they are OK with it, put them in booties and avoid problems together.

A．It takes a dog about ten days to adjust to any temperature change

B．Give them a heat source

C．Don’t force it to get dressed

D．Take your dog out even in cold weather

E．Compare and purchase the soft clothes for it

F．Make sure you wipe your pup’s feet after every walk

G．The prospect of facing the winter cold may not be so inviting

I was eight years old and wasn’t aware of all the arrangements being made for our journey as a family to London in 1950. My mother was in great pain and wished to visit specialists in London. My father reluctantly had to sell our property in Queensland. The day before we boarded the ship, Father unwillingly said goodbye to his five-year-old cattle dog, Spider, who was loved by us all. Father’s friend Sandy was to be his guardian while we were overseas, as he had been getting to know Spider for many weeks.

Six weeks later, an airletter arrived from Sandy, giving my father the news that Spider had run away just two weeks after we had sailed. Sandy had advertised constantly on ABC and other regional newspapers. Despite many “sightings”, the dog was never found. It seems Spider just kept running and searching for us. As he was cattle dog, my father thought he would shoe or dingo-trapped, because of his appearance. But our family thought that Father held a secrets hope that Spider was still alive.

We sailed back to Australia two years later and re-established our home. My father immediately began his own search for Spider. One cold winter’s Saturday morning eight months after our return, my father had a call from an elderly lady living on her own on the outskirts of the town. As she told my father on the telephone, it was “just glimpses of a dingo-type dog in the shadows” of her disused tennis court. That was enough for my father to interrupt my homework.   

We set off in his blue and black Jensen car which he had brought back from England. It was hardly the right vehicle for the rough roads we travelled that day. Five and a half hours later, we found the run-down old property. Sadly, she told my father that the “dingo dog” hadn’t been around for a few days. My father had a strange look in his eye. He put two fingers to his lips and did his special whistle for Spider.
