1 . Sara Dykman is on a 10, 000-mile bike trip, following the monarch butterfly from Mexico through the UnitedStates and Canada and back again. The purpose of her journey is not just to mark the butterfly’s migrating (迁徙) road, but to warn about the threat it faces — and what we can do to help it.
When I reached Dykman by phone, she was biking through Iowa cornfields. She said she feels more upset than usual, because of what she is seeing — or not seeing — on her travels: Fewer butterflies and milkweed. “In the last two decades, the butterfly population has declined by about 90 percent as a result of the loss of milkweed, a native plant that the butterflies need as part of their life cycle,” she said.
Butterflies go through a four-stage life cycle. In February and March, the adult monarch butterflies come out of winter sleep to look for a mate. Then they migrate north and east to lay their eggs on milkweed plants. It takes about four days for the eggs to hatch. Then the baby caterpillars (毛毛虫) spend much of their time eating milkweed in order to grow. About two weeks later, the fully grown caterpillars will attach themselves to plant branches or leaves to change into butterflies.
But Dykman is not in total despair. A solution, she says, exists within the reach of everyone who owns a home; simply planting some milkweed in the yards to help the butterflies on their journey.
Dykman lives a life as simple and rootless as the butterflies she loves. She doesn’t own a house or car or eat out at restaurants. She carries only what she needs; a sleeping bag and clothing. People help along the way by providing a place to stay and a meal.
“I have failed at everything normal, but I’m pretty good at doing the less normal things,” she admits in her new book Cycling With Butterflies.
“But this trip is about solutions, and it’s about helping people see the consequences of their actions,” she said on the phone.

2 . 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.

3 . A dog can be a person’s best friend, or so the theory goes. But that relationship can be tested when a dog begins barking at an empty comer of a room, at a door, or anywhere where there doesn’t appear to be any activity at all taking place. Is the dog hallucinating? Is it communicating with ET? Or does it simply want to drive its owner crazy?
According to the American Kennel Club, the most common explanation for dogs’ barking without reasons is that it’s not really unprompted at all. Dogs are, obviously, equipped with superior hearing, including the ability to detect sounds that are higher in pitch. It is said a dog could be reacting to a noise that a person wouldn’t be able to hear. If a dog barks seemingly for no apparent reason at night, it might be because the noise nearby is lessened and some barking of other dogs become more clearly. Because dogs are territorial, one dog barking can turn into many others to guard themselves.
Dogs are also able to see better in the dark than humans thanks to their ability to get more light into their retinas (视网膜). If a dog is reacting to what looks to you like an empty backyard at night, it’s possible that something has caught their attention, be it a wild animal, a leaf, or a stranger.
That’s not to say that dogs only bark because of their cute senses. Some dogs might bark out of boredom in which case more exercise or play time is probably needed. They might also be trying to get their owner’s attention.
The AKC recommends that owners avoid scolding their dogs for barking, since they’re simply trying to remain alert, instead, you can try calming the dog to let them know you’re aware of their concern. If they tend to bark while gazing out a window, you can also try to pull the curtains. If you suspect the source is an audio cue, some white noise, like a television or radio can help.
Less often, chronic barking might be a sign of cognitive issues. If barking is persistent and no fugitive is hiding out in your bushes, then you might consider a trip to the vet.
1. According to the passage, which factors won’t make dogs barking at nothing?| A．Its madness. | B．Its visual sense. | C．Its acute hearing. | D．Its boredom. |
| A．A dog barks in order to make friends with other dogs. |
| B．The surrounding noise being lessened will make a dog frightened. |
| C．A dog can react to a noise as acutely as a person. |
| D．A dog always has the awareness of its domain. |
| A．Leaving it alone. | B．Scolding it seriously. |
| C．Comforting it. | D．Playing some soft music. |
| A．an experiment report | B．a mental discovery |
| C．a school textbook | D．a science fiction |
4 . 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.

5 . Safe Haven for Donkeys (驴) is providing sanctuary for rescued working donkeys in the El Saf region of Egypt.
First established in 2000 to help thousands of working donkeys in Israel, the charity Safe Haven for Donkeys has begun working with an Egyptian partner organization, the Bridge Foundation, to provide care to the donkeys in the El Saf region of Egypt.
Thousands of donkeys work in the brick kilns (窑) in Egypt, carrying 1.4 to 1.6 tonnes of bricks and moving at an intense pace to prevent unfired bricks from cracking in the heat. Due to lacking expert veterinary (兽医的) care, many of these animals are suffering intense pain from harness wounds, beatings, hoof issues and parasitic diseases spread by flies.
Now the cooperation between UK charity Safe Haven for Donkeys and Egyptian community development charity the Bridge Foundation is providing much-needed relief to these animals. The project includes a mobile veterinary clinic which treats common injuries and infections and trains the owners in how to best look after their donkeys.
In a press release, Andy Foxcroft, CEO of Safe Haven for Donkeys, said, “Through our work in Israel, we came to know of millions of working animals in Egypt without critical veterinary care. They were suffering a host of preventable and treatable painful conditions. Currently. no other animal welfare charity provides veterinary interventions in these particular kilns. So the skills of this charity are needed to treat sick and injured animals and provide training for owners and local professionals (vets and farriers). The first year is vital as we hope to make a lasting impact by reducing the unnecessary suffering of working animals. which sadly, is all too common a feature in the brick kilns.”
Safe Haven for Donkeys’ work, which helps about 10,000 animals a year, is made possible by charitable donations that fund the treatment and training they offer. You can make a donation on its website.

My parents were always against me owning my own pet, afraid of the mess it would make or that I would quickly lose interest in taking care of it, but we made a compromise: I could volunteer at a local pet shelter on the weekends to test my sense of responsibility and dedication. That was how I first came to volunteer at the Avondale pet shelter and—more importantly—where I met my future best friend, Chocolate.
One hot August afternoon, my boss Charlie told me that they were bringing in a young black Labrador Retriever and that I’d be its primary caretaker. An hour after our conversation and in came Chocolate—a beautiful dog with shining brown fur and amazing blue eyes. At about 3 months old, I expected him to be a lot more energetic and playful, but he immediately backed and lay down at the back of his pen (围栏).
I asked Charlie what was the matter with him. He replied that Chocolate had a genetic problem which caused him to be born with a short tail, leading potential owners to think there was something wrong with him; so the breeder felt that they had no choice but to give up the puppy to the shelter.
He was overlooked and underappreciated. I felt very angry at the thought that an otherwise healthy dog could be thrown away so easily. At the same time, I felt a deep sympathy for this dog who had been cheated out of the love and attention he deserved. It was at this moment that I resolved to give Chocolate as much love and attention as I could while working as a volunteer.
Although Chocolate was reluctant and shy at first. eventually through enough treats and play he slowly came around and warmed up to me. Soon enough, whenever I came around his pen to let him out for his turn of walks and play, Chocolate was always excited and jumping with joy.

9 . The Monarch butterfly (帝王蝶) population has dropped to its second-lowest number on record in Mexican forests this winter. The forests are the insects’ winter home. The population decrease is worrying as the butterfly group is already considered at risk of disappearance.
Mexico’s government and the non-profit World Wildlife Fund (WWF) recently issued findings of their yearly joint study on the butterflies. The research shows that the Monarch butterfly presence has decreased to less than a hectare (公顷) of forest area. In the mid-1990s, Monarch butterflies could be found on around 18 hectares of the forests. The findings represent an almost 60 percent decrease in the Monarch butterfly population compared to last year’s study. It is also the second-lowest population finding since the first study took place more than thirty years ago.
Biologists blame the drop on higher-than-usual temperatures and dry conditions in the northwestern U. S. where the butterflies lay eggs. The weather conditions affect the growth of milkweed, the plant where the butterflies lay their eggs. When the young arrive, milkweed is their food for a time. In one of the planet’s famous wildlife migrations (迁徙), the butterflies travel south as many as 4,500 kilometers from places as far north as Canada. They spend the winter in warmer Mexico, where millions of the insects stay in trees that protect them from the rain and cold.
Monarch butterfly populations change year to year. As recently as 2021, the same study showed a 35 percent increase to cover around 2.8 hectares. Officials and activists called for more action to help the species. Such calls include the need to reduce threats of destroying milkweed and the need to protect forests. “We can’t lower our guard,” Jorge Rickards, head of WWF’s Mexico office, told reporters after releasing the latest data.

10 . In the Seychelles archipelago (塞舌尔群岛) in East Africa, flooding and erosion (侵蚀) caused by rising sea level pose an incoming threat to the country’s many low-lying islands. At the same time its mangrove forests (红树林), which serve as a vital aspect against these impacts, are disappearing: Approximately 70% of Seychelles mangroves have been destroyed since the late 1700s due to human-driven development and agriculture as well as soil erosion from sea-level rise.
Today the Seychelles Government is working with local community leaders to restore the mangroves, and not just for protection against rising sealevel. Research shows that these forests can store about 2.5 million tonnes of CO2 (equal to taking 500,000 cars off the road for a year), directly helping to fight climate change. They also provide a breeding ground for fisheries, a sector that contributes one-fifth of the country’s GDP, benefiting local communities’ livelihood and helping to protect the islands’ lively biodiversity (多样性).
While the concept of using nature to benefit both lives and lands is by no means new, global interest in “nature-based solutions” has skyrocketed in recent years. Many now see nature-based solutions as a key approach for addressing not only climate change but a range of social, environmental and economic challenges—from biodiversity loss, food security and air pollution to disease control and declining local economies.
Yet there remains widespread debate about what exactly constitutes a nature-based solution as well as how to best include these strategies into broader climate and conservation efforts. This indetermination has contributed to significant under-investment: It’s estimated that to limit temperature rise to below 1.5 degrees C (degrees F), hold back biodiversity loss and control land degradation (恶化), annual investments in nature-based approaches must be three times by 2030.
As nature-based solutions continue to rise on the global agenda, building a more consistent understanding around the concept and its implications will be key to raising support for effective, extensive solutions that benefit both people and the planet.
