Brought up in a family of animal lovers in a small town in New Mexico, Steve Greig's parents instilled（灌输） in him the importance of adopting shelter dogs. Steve's journey into senior dog adoption began with heartbreak in 2012. When his beloved companion, Wolfgang, passed away at the age of 12 after being hit by a car, Steve was devastated.
The sadness lingered（继续存留） for months, and he longed for something positive to emerge from the pain. Seeking comfort and a way to honor Wolfgang's memory, Steve decided to visit the local shelter to adopt the oldest dog in need.
Little did he know that this decision would reshape his life. At the shelter, a 12-year-old Chihuahua named Eeyore captured Steve's heart. Steve felt an instant connection, a sense that he could help this dog live a fulfilling life. With one ear pointing down and the other sticking up, Eeyore became the first senior animal that Steve welcomed into his home.
From then on, Steve realized that senior dog adoption and adopting animals with disabilities were his calling. It was a way to honor Wolfgang's memory and, more importantly, a healing method for Steve himself. Eeyore's presence was profound, inspiring Steve to continue adopting senior animals. His mixed family expanded to include a variety of characters—a pig named Bikini, a rabbit, two ducks, four chickens, and even a turkey named Tofu.
Reflecting on his unique family dynamic, Steve acknowledges the unexpected blessings of joy, fame, and friendship that have come his way. The pain of Wolfgang's loss has transformed into a purposeful mission, bringing diverse and heartwarming experiences into his life.
For Steve, senior dog adoption isn't just about providing a home; it's about embracing the best version of each animal. He encourages others to consider adopting seniors, emphasizing the ease and fulfillment of caring for older dogs.
Researchers have developed a groundbreaking method of storing and handling valuable biological materials that removes the limitations of refrigerated storage. The novel method has potential applications in healthcare and scientific research.
Biological materials that come from human cells, like enzymes, proteins, and antibodies, are crucial to developing new medicines and diagnostic tests. And they're fragile. Extremely temperature-sensitive, they require a constant temperature during storage, handling, and transportation. If not stored or handled correctly, these materials will be inactive, which can be costly.
Most biological materials are stored as liquids or freeze-dried powders and kept at low temperatures for the duration of their shelf life. This is achieved through a complex integrated system of refrigerators and freezers known as the cold chain. This requires a significant investment in equipment and infrastructure, making it expensive to maintain, and makes the cold chain prone to shipping delays, power outages, equipment failure and human error.
Inspired from the home medicine cabinet（储藏柜）， where medications are stored in the form of liquids, powder-filled capsules, and tablets, researchers at California Polytechnic State University have developed a new storage platform based on the humble table t that would enable biological materials to be compressed （压缩） into a solid state.
Tablets provide advantages to the storage and handling of biomaterials that the cold chain doesn't. For one thing, they can be stored at room temperature. And, when they're required, the tablet can be dissolved in water. "Our innovation makes storing and using biomaterials as straightforward as an effervescent tablet （泡腾片）. Just drop it into water, mix, and it's ready to go," said the researcher of the study.
The researchers say their new tablet-based storage and handling method is easy to use and doesn't require special training, making it suitable for many applications. They also see potential uses beyond just improving the storage and handling of biological materials. By modifying（修改） the tablet coatings, this solid-state storage platform could withstand extreme conditions like heat, humidity, and chemicals. These changes might eventually allow injectable medications, such as insulin, to be taken orally.
Exercise lowers the risk of many diseases, but scientists still don't fully understand how exercise changes the body on a molecular （分子的） level. Most studies have focused on a single organ, sex, or time point, and only include one or two data types.
To take a more comprehensive look at the biology of exercise, scientists with the Molecular Transducers of Physical Activity Consortium (MoTrPAC) used a range of techniques in the lab to analyze molecular changes in rats as they were put through the paces of weeks of intense exercise.
The team studied a range of tissues from the animals, such as the heart, brain, and lungs. They found that each of the organs they looked at changed with exercise, helping the body to regulate the immune system（免疫系统）， respond to stress, and control pathways connected to inflammatory（发炎的） liver disease, heart disease, and tissue injury.
The data provide potential clues into many different human health conditions; for example, the researchers found a possible explanation for why the liver becomes less fatty during exercise, which could help in the development of new treatments for non-alcoholic fatty liver disease.
The team hopes that their findings could one day be used to tailor exercise to an individual's health status or to develop treatments that mimic the effects of physical activity for people who are unable to exercise. They have already started studies on people to track the molecular effects of exercise.
"It took a village of scientists with distinct scientific backgrounds to generate and integrate the massive amount of high-quality data," said a co-senior author of the study. "This is the first whole-organism map looking at the effects of training in multiple different organs. The resource produced will be enormously valuable, and has already produced many potentially novel biological insights for further exploration."
Learning a foreign language can be difficult, but if you follow certain techniques, you'll be able to learn any language soon. Although there's no easy way to go about it, with some hard work and practice, you can be fluent in the near future.
Learn from your past experience. If you've learned languages in the past, go over what you learned then and try to figure out what was most effective for you. What didn't? Which parts of the process did you find easy? Which parts were hard? When you've sorted this out, you'll be ready to start learning the language.
Study English Phonology （音系学）. English Phonology deals with English pronunciation.You can find many websites and online videos on English Phonology. Relate English pronunciation with other language pronunciation.
Pay attention to the grammar. "Paul want Mary go store" may communicate an idea, but it is not at all correct English. If you do not pay attention to grammar, you can sound equally incomprehensible in another language.
Just imagine you went to a shopping center. Then think how you would interact with people. Write the whole conversation in your native language then translate every sentence into the required language.

You may not be able to imagine the impact your hard work and dedication can have on others. The following story may show you that.
Everyone 1 that in addition to the vows（誓言） during the wedding ceremony, rings are 2 . The rings are a sign of that never-ending commitment, becoming 3 pieces of jewellery because of the significance.
So, when Melanie Harper 4 her wedding ring, it's easy to imagine the 5 she must have felt. She was placing garbage in a recycle bin when the ring slipped off her 6 and into the endless sea of recyclable material.
Melanie, trying to 7 the ring, reached out to the Greenville Department of Public Works. The department's supervisor（主管人） had sympathy for Melanie. He put himself in her 8 and then made a decision.
They 9 the contents of the container all over the parking lot and then began 10 through the garbage, looking for the lost ring. The probability of finding something so small is tiny, next to 11 . Luckily, the supervisor did 12 to find the ring!
After the ring was recovered and returned to Melanie, she met up with the men to express her 13 gratitude. She thanked them for their kindness and 14 . What a terrific example of how our efforts and hard work can and do 15 impact the lives of others!
A total of 102 architectural heritage projects is revealed at the "Public Vision of 20th-Century Heritage—Introduction of the 9th Batch of China's 20th-Century Architectural Heritage Projects and Seminar" held in Tianjin on Saturday. Experts said, "China has shifted 'cultural relic protection' to 'cultural heritage protection' and this (aware)will provide new possibilities for urban development and cultural preservation."
According to the chairman of the China Cultural Relics Academy and director of the Academic Committee of the Palace Museum, "activation" is the focus of the protection of these buildings. 20th-century architectural heritage is not 'frozen', but (change) with the times. A historical building or zone must be given (today) functions, and used correctly and reasonably.
(compare) with traditional wooden ancient buildings, industrial heritage has a wider range of uses. Taking Beijing's Shougang Park as example, the chairman introduced the importance of "activation".
Shougang Park, now has become an industrial heritage park after ceasing production, used (be) a steel production base. Many large-scale cultural, tourism, and sports activities are taking place in Shougang Park, and its functions are (constant) expanding.
According to experts, protecting 20th-century architectural heritage is a collective responsibility. The preservation shouldn't (undertake) by the government or cultural sectors alone. Everyone should contribute to this cause.
According to experts, the work is not just the task of the government or cultural departments but the responsibility of all people.
Years later, I might still remember that small library. It was a winter day when I came to the library. The sunlight was bright but not warm. It was a typical southern winter day, windless but cold.
The winter vacation was crucial for me, and studying in the library could efficiently improve my studies. I stood in front of the door with my backpack. On the board on the door read: "Community Library". I pushed the door open. Behind the service desk sat an old man with gray hair and dark skin, wearing reading glasses. When he saw me, he pushed his glasses up.
"Hello, I live nearby. My home is small and noisy. Can I study here?" I asked. The old man looked me over and nodded. I then moved to a table in the corner. After lunch every day, I would come to the library. Most of the time, it was just the old man and me, and the only sound was the hum（嗡嗡声） of the old air conditioner.
When I felt too cold or tired of reading, I would get up and move around. Gradually, the old man would ask me if I needed hot water. Sometimes he brought me subject-related books. We had brief conversations sometimes. The old man grew up in the countryside and didn't have much education. He worked in a factory when he was young, and after retiring, he came to the community library to work.
Every day, I studied until sunset. When it was about time for the old man to get off work, I would pack up and get ready to leave. He would also stand up and tidy up. After I left, he would close the door, ending his day's work.
One afternoon, I went to the library to return some books. The old man was very happy that day and handed me a book, saying, "I found a book on the far right of the shelf in the corner. I'm sure you'll like it" I nodded, took the book, and thanked him.
注意：
1.续写词数应为150个左右；
2.请按如下格式在答题卡的相应位置作答。
A week later, I went to return the book, only to find an old lady locking the door. …… "Then why did the library close around 4 pm during the last few weeks?" I asked. |
