Horses are picky eaters
Horses have an even better sense of smell than humans do. When horses raise their noses and open their nostrils (鼻孔), their nervous system allows them to sense smells we can’t sense. This might explain why they refuse dirty water and carefully move around meadows, eating only the tastiest grasses, experts say.
Whale says thanks
In 2018, a whale expert spotted a humpback whale trapped in a fishing net and spent an hour freeing it. Afterward, in an hour-long display of thanks, the whale swam near their boat and leaped into the air about 40 times.
Pandas like to be naughty
Is there anything more lovely than a baby panda, except maybe a human baby? In fact, baby pandas sometimes behave like human babies. They sleep in the same positions and value their thumbs. Pandas are shy by nature for its shy behaviors such as covering its face with a paw or ducking its head when confronted by a stranger.
A cat honors its owner
Paper towels, and a plastic cup are just a few of the gifts that Toldo, a devoted three-year-old gray-and-white cat, has placed on his former owner Iozzelli Renzo’s grave every day since the man died in September 2018. Renzo adopted Toldo from a shelter when the cat was three months old, and the two formed an inseparable bond. After Renzo passed away, Toldo followed the coffin to the cemetery, and now “stands guard” the grave for hours at a time.

2 . The UK will ban all new petrol and diesel-powered vehicles from its roads beginning in 19 years for environmental reasons, a government report says.
The plan aims to start removing petrol and diesel engines in 2040. It follows a similar official statement in France and comes after the British government was ordered by the High Court to develop new plans to reduce NO2 in the air. Judges ruled that previous clean-air plans were not enough to meet European Union pollution limits in the coming years.
The British government has said the poor air quality has an unnecessary and avoidable negative effect on citizens’ health, and costs up to $3.5 billion in annual lost productivity.
Part of the new plan involves an offer of $260 million to local governments to change rules where vehicle emissions (排放量) are over EU standards. Ideas so far include changing road layouts, reprogramming traffic lights and charging a fee for the oldest and most polluting cars on the road.
The plan also includes $1.3 billion for government purchase of extreme-low-emission vehicles, nearly $130 million to improve infrastructure for electric vehicle charging stations and $378 million for remodeling existing vehicles.
Climate change is also a reason for the plan to get these vehicles off the road. “We can’t carry on with petrol and diesel cars,” Environment Secretary Michael Gove said. “It’s important that we all prepare for a significant change which deals not just with the problems of health caused by emissions, but the broader problems caused in terms of accelerating climate change.”
Gove added that local communities are partly responsible for coming up with ways to limit emissions, including possible limitations on commuters (上下班往返的人) and the addition of cleaner mass transportation options. Local leaders are called on to draw up “appropriate plans” to deal with climate challenges related to emissions, he said.

3 . More and more birds are flying to settle at Qinghai Lake, one of the highest inland lakes in China, thanks to the protection efforts of local governments. Covering an area of over 4,000 square kilometers. Qinghai Lake is also the country's biggest saltwater lake. Located in Northwest China's Qinghai Province, the lake is famous for the two islands at its northwest point--Cormorant Island and Egg Island. The two islands have plenty of floating grass and various schools of fish, offering rich food sources for birds. The islands have become a paradise(天堂) for different kinds of groups of birds and have been called"Bird Islands".
Each March and April, when ice and snow covering the Qinghai-Tibet Plateau starts to melt, over 20 kinds of birds fly to the Bird Islands to lay eggs. During the months, flocks of birds cover the whole sky over the islands and birds eggs can be found everywhere. Visitors can hear the singing of birds from miles away. These have become a world famous symbol of the lake.
To protect this paradise for birds and support calls for ecological protection, China set up the Qinghai Lake Natural Protection Zone at the end of 1997. Meanwhile, the State has pointed out the Bird Islands and Spring bay of the Qinghai Lake as central protection zones.
Inspection(视察) officials and management employees often patrol(巡逻) the lake, improving local residents' knowledge of related laws and spreading knowledge about animal protection to visitors. They are making great efforts to call on people to love and protect the birds. At the same time, they have built special fences around the island area to prevent wolves, foxes and other carnivorous(食肉的) animals, as well as illegal hunters from breaking up the birds’nest building,egglaying and breeding. As a result, more and more birds are coming to the islands for sheltering and breeding.
1. Why are more and more birds coming to the biggest salt-water lake in the Great Northwest?A.Because it is getting warmer and warmer. |
B.Because it is being reformed. |
C.Because environments there are getting more and more agreeable for them to live in. |

A.floating fish and various grass. |
B.grass moving on the water surface and different kinds of fish. |
C.salt water and plenty of grains. |
D.corn from the local farmers. |
A.The ice and snow covering the Qinghai-Tibet Plateau doesn't change into water. |
B.Flocks of birds fly up to the whole sky over islands to lay eggs. |
C.Visitors can listen to the singing of birds from miles away, but they couldn't see any bird. |
D."The ice on the Plateau begins to change into water" means spring is coming. |
A.let the farmers there know the animal protection law. |
B.tell the farmers there some knowledge about animal protection. |
C.call on people to love and protect the bird. |
D.all of the above. |
4 . Baby giraffes inherit(经遗传获得) aspects of their mothers’ patterning — which could give them a survival advantage if good camouflage(保护色) runs in the family. Just like humans have unique sets of fingerprints, every giraffe has a unique set of spots.
Derek Lee is a wildlife biologist and population ecologist at Penn State, and with the Wild Nature Institute, a research consulting group. He and his colleagues have been tracking giraffes for seven years, throughout 1,500 square miles in Tanzania.
Now, they’ve used image analysis software to study the spots of mothers and their babies. And they found that baby giraffes inherit at least some particular elements of their patterning from their mothers, like how circular the spots are. They also found that baby giraffes with larger spots have better chance to survive their first months, because the spots are more like the dappled(斑驳的) sunlight in the bushes where baby giraffes like to hide from hungry lions and hyenas (wild animals like dogs).
The results — and a lot of giraffe patterns — are recorded and explained in the journal PeerJ. [Lee et al., Seeing spots: quantifying mother-offspring similarity and assessing fitness consequences of coat pattern traits in a wild population of giraffes (Giraffa camelopardalis)]
It’s perhaps not surprising that a physical characteristic that protects an individual from being eaten passes the test of Darwinian natural selection — and get passed along to later generations. “The fact that these things are inheritable and they did affect survival of baby animals makes us feel like evolution is embodied exactly by these spot features.” So if a mom’s camouflage is good, her babies, too, might have the spots that keep them safer.
1. Why are baby giraffes with larger spots more likely to survive?A.Their spots match surroundings better. | B.They keep away from lions and hyenas. |
C.Their mothers tend to protect them more. | D.They barely move around in the bushes. |

C.Provide evidence for the findings. | D.Introduce a new topic for discussion. |
A.Promoted. | B.Represented. | C.Questioned. | D.Prevented. |
A.Animals have their unique sets of patterning | B.Mom’s genes make some giraffes hard to spot |
C.Derek Lee has been studying animal patterning | D.Animal physical characteristics are similar to family’s |

6 . When Simon Cane was in the second grade, he began learning about all the ways humans have an impact on the environment and really took those classroom lessons to heart in a way that set him apart from his schoolmates at his elementary school, P. S. 81, in the Bronx. “He told me we drove too much and made too much pollution,” his dad, Jonathan Cane, told Runner’s World. So Simon convinced his parents to start hanging their clothes to dry, taking the stairs instead of elevators, and other “green” measures.
“For much of kindergarten and first grade I rode my bike to Simon’s school with him on the back,” Jonathan said. “We had a lot of fun being outdoors. We’d stop to give our dog treats and generally enjoyed it.” As Simon got bigger, though, it wasn’t practical for him to ride on his father’s back, but it also didn’t make sense to ride together — both because of safety concerns and because there was no place to put away Simon’s bike. So, most of the time they drove the 1. 5 miles to school.
But in 2019, when Simon was going into third grade, the 8-year-old came up with a new way to help the planet: running the 1. 5 miles to P. S. 81. And Jonathan promised his son he’d join him for as long as he wanted.
“We did a test run one day in August, and decided to give it a go. To be honest, I thought he’d blink (眨眼)after it got really cold or rainy, but he never did,” Jonathan said. He recalled one day when the weather was particularly bad. “It’s really raining out there today,” he told Simon. “And Simon said, ‘Well then we’re going to get wet!’ He took pride in toughing it out, and it became a really fun family routine.”
Since the start, Simon has run with his dad and their black dog, Lola, and has even inspired his mom, Nicole Sin Quee, to join in. They soon became known as “the family that runs to school”.

7 . Conservationists have long known that using pandas, tigers and other charismatic(有号召力的) species to front their campaigns is a good way to raise money. But some people argue that focusing on these “flagship” animals can ignore equally threatened but less cute ones.
Now Jennifer McGowan at Macquarie University in Sydney and her colleagues suggest that we can have it both ways, after finding that funding for flagship species also helps other threatened species in the surrounding areas. McGowan’s team first drew up a list of 534 flagship species in wildlife-rich hot spots around the world. The biodiversity areas were each split into grids (网格) of 100 by 100 kilometre squares. The researchers then compared two conservation approaches across eight simulated scenarios(模拟场景) which assumed different levels of human activity and protected areas.
The first focused on protecting flagship species, while the second aimed to protect the maximum number of species in an area, regardless of their fundraising potential. Their study has found that targeting grid squares with flagship species also protected 79 to 89 per cent of the non-flagship species in that area. The figure rose to 97 per cent in some scenarios. “The findings could help when choosing which species to promote. Flagship species are very effective at getting the public to care,” she says.
Morgan Trimble, the author of a paper that has found scientists also have a bias towards charismatic animals, says the results don’t surprise her. “While I think it’s important that we don’t lose sight of the bigger picture --- conserving species is about conserving all the component parts of ecosystems, even the not-so-cute species --- I think highlighting flagship species in fundraising and education is a practical idea and appeals to human nature,” she says. Trimble also asks what the alternative to using flagship species would be: randomly picking species? McGowan’s study found a random approach to choosing where to spend conservation funds only protected 39 to 55 per cent of the non-flagship species.

10 . It is not just doctors and nurses that work at Children' s National Hospital in Michigan. There are also two furry friends on the staff.
Their main responsibility is to comfort the young patients at the hospital. Their work called animal-assisted therapy.
Facility dogs are expertly trained dogs who partner with a facilitator working in a health care, visitation or education setting. They would visit kids for a hug or paw shake. More than just dogs can be animal therapists.
