1 . 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.
• Keep the walks brief
•
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.
• Watch out for dangerous snow
Salt and antifreeze on sidewalks are potentially deadly to pets.
| A．It takes a dog about ten days to adjust to any temperature change |
| B．Give them a heat source |

3 . Parrots are prey animals, which means that other predators (捕食者) in the wild, such as hawks or snakes, are looking to make them into a meal. This one factor influences parrots’ behavior in your house more than any other.
Parrots are most easily hurt when feeding on the ground. Membership in a group plays an important function in ensuring their safety and improving their chances of survival from attacks by predators. The most common predators of parrots include hawks, snakes, cats, monkeys, and bats. Some predators make attacks only during the day while others hunt in the night.
As prey animals, parrots are constantly watching out for danger and they instinctively (本能地) react to risks. Their first choice is to take flight. However, if this is not possible, they will fight with their powerful beaks to defend themselves.
Because their biggest enemy is the hawk, parrots are especially reactive to quick movements from above and behind. For this reason, it is wise to avoid quick, sudden movements near your bird. This is a built-in reaction not subject to logic or reason. Simple and relatively harmless household objects can draw extreme fear responses from a bird. For example, a balloon may represent a hawk or a vacuum hose (吸尘器软管) may be the same as a snake in your bird’s mind.
As prey animals, parrots are often frightened by exposure to new household items or strangers. It is important to expose your bird to safe experiences and changes starting at a very young age to build flexibility and improve their adaptability. Variety in diet and toys, travel, and exposure to new people and places all help to make your bird more flexible and adaptable to change.

6 . Plant biologists have found a way that may enable poor farmers to do away with the need to purchase expensive hybrid seeds every year. Researchers at the University of California report that they have solved a long-standing problem of hybrid seeds by making exact clones of the hybrid plants from seeds.
For long, many crops have been grown from high-yielding, anti-disease or climate-tolerant hybrid seeds. But the seeds of hybrid crops do not produce plants with the same qualities during reproduction and hence farmers cannot save the seeds for the next growing season. They end up paying for new hybrid seeds each sowing season. The discovery, long sought by plant researchers, could make it easier to grow desirable high-yielding crops and make them available to the world’s farmers. Farmers could thus replant seeds from their own hybrid plants and enjoy the benefits of high production year after year, the scientists report.
While the discovery would help farmers, it would also impact the commercial interest of the hybrid seed industry. Siddiq, a former Deputy Director General in the Crop Science Division of the ICAR, said at first sight, this might seem like a setback for hybrid seed companies but there would be plenty of things they can still do. “Rice is grown over such a vast climatic and geographical range that specialized hybrids would have to be developed for each region,” he said. The companies, he said, would continue to improve their hybrids. “It will be interesting to see how all this plays out in the years to come.”
Currently, the high costs of producing hybrid seeds are a major barrier to farmers in developing countries, especially South Asia and Africa. Siddiq said if efficiently used, this method could potentially be a game-changer for poor farmers, who would need to purchase hybrid seeds just once and plant the progeny(后代) seeds from their own harvest in the following seasons.

7 . Children returned to school after a big wildfire in Northern California. But the influence is so huge that it will be some time before the life of students there returns to normal.
Eight schools were lost to the wildfire. Government officials were not sure how many of their nearly 3,500 students would report to temporary (临时的) schools. Some families have left California. Others are staying with friends. It is too far for some of them to drive to one of those schools every day.
There are not enough classrooms for middle and high schools. So for the l3 days before the start of the traditional winter break in the school year, students will learn through independent study. They will be given homework online and be able to visit a special drop-in center in Chico, California. Children going there can get help from teachers or visit other classmates.
Loren Lighthall, a spokesman for one school there, said studying will be less important than dealing with pain and reconnecting with friends. “They don’t have their school, they don’t have their work, they don’t have their friends, they don’t have books and we’re asking them to do homework?” Light hall said. “It’s less important at this point. We’re going to do it. But what is important now is to deal with the pain left.”
Search members have stopped looking for the lost in burned cars and houses. But they remain available whenever there is need for help.

8 . A blue hole is a special kind of underwater cave found inland or in the sea, which forms when the earth above a cave falls in and water fills the space.
An inland blue hole’s water is very still and has different layers. A layer of fresh rainwater floats on top of salt water; the fresh water keeps oxygen from the atmosphere from reaching the salt water; brightly colored bacteria live where the two layers meet.
Diving into blue holes is very dangerous. Near the top of the blue hole, there is a layer of toxic gas, which causes itching, headache, and—in large amounts—death. Divers must also be fast. They have to get in and out of a cave before their oxygen runs out. Additionally, divers have to follow a guideline as they swim through a blue hole because it is very dark inside. Without the guideline, they may get lost.
If blue holes are so dangerous, why do explorers and scientists risk their lives to explore them? The reason is that these underwater caves can provide valuable scientific information. They provide clues about geology, archaeology, and biology. For example, some blue hole creatures probably haven’t changed for millions of years.
The blue holes could even provide clues about astrobiology. For example, divers have found bacteria there that can live without oxygen. Astrobiologist Kevin Hand says the bacteria may be similar to forms of life that might exist on Jupiter’s fourth largest moon, Europa. “Our study of life’s extremes on Earth,” he says, can help increase “our understanding of habitable environments off Earth.”
In addition, the oxygen-free environment of the blue holes preserves bones of humans and animals that fell into the caves long ago. By studying blue holes, we can understand what life was like in prehistoric times. As cave diver Kenny Broad says, “I can think of no other environment on Earth that is so challenging to explore and gives us back so much scientifically.”

10 . Tall, long-necked giraffes are famous for their spots which are believed to help the animals hide from their enemies. Just like no two humans have the same fingerprints, each giraffe has its own special pattern of spots. However, a Tennessee zoo made headlines recently after it welcomed one of the world’s most uncommon giraffes.
On July 31, a baby giraffe was born at Brights Zoo with light brown fur which is a reticulated (网状的) giraffe, one of the four different kinds of giraffes. Unlike most giraffes, she was born without spots, a unique feature of the reticulated giraffe. At six feet tall, this baby giraffe is growing well under her mother’s care. She shows typical baby giraffe behavior, such as eating rocks.
Experts said the young giraffe was the only single-colored reticulated giraffe living anywhere on the planet. The last time this happened was 1972 in Japan. A giraffe’s pattern of spots is created when the animal is still growing inside its mother. That means that this giraffe will never have spots.
“The new giraffe might not have survived if she had been born in the wild. Being single-colored, she may not be able to hide quite as well,” said Mr. David Bright, who runs the zoo, “It will easily be a key target for poachers (偷猎者) because she’s so unusual.”
Brights Zoo stressed that reticulated giraffes had already become imperiled. In 2018, they were officially listed as “threatened”. Thirty-five years ago, there were 36,000 reticulated giraffes. Now, the number has been cut by more than 50%. Only about 16,000 reticulated giraffes remain.
This brown giraffe’s birth is not only a rare and fascinating event, but also an opportunity to raise awareness about the challenges faced by giraffes in the wild. By supporting efforts like this, we can contribute to the conservation of these large creatures and ensure their survival for generations to come.
