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.
(1)、What is a special requirement to store biological materials?A、Constant temperature maintenance. B、Exposure to various temperatures. C、Periodically freezing and melting. D、Direct contact with air.(2)、What is the researchers' attitude to their storage method?A、Favorable. B、Skeptical. C、Disappointed. D、Grateful.(3)、Which word can replace the underlined word "withstand" in the last paragraph?A、Demonstrate. B、Stand. C、Adopt. D、Distinguish.(4)、What is the text mainly about?A、Challenges of storing biological materials. B、The making process of effervescent tablets. C、Healthcare applications of biological materials. D、A new table t storage method of biological materials. -

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.
(1)、What might Steve's parents have taught him?A、To care for animals. B、The importance of success. C、To long for positives things. D、The way to recover from sadness.(2)、Why did Steve visit the local shelter?A、To donate money to it. B、To find a way to reshape his life. C、To seek more animals in need of help. D、To select a poor elderly dog from it.(3)、What inspired Steve to continue adopting senior animals?A、The fame he received from the media. B、The deep impact of Eeyore's presence.

14、阅读下面材料,根据其内容和所给段落开头语续写两段,使之构成一篇完整的短文。
Edward and Stephen were both eighteen years old. They were so together in friendship that they felt themselves to be brothers. They had known each other since childhood, growing up in the same block in Liverpool.
Edward was fair and lean, while Stephen was dark and short. Edward's brown hair was always falling over his eyes, while Stephen wore his black hair in a natural style.
Each youngster had a dream of someday becoming champion of the world. Whenever they had time, the boys worked out at the Fencing (击剑) Club. Early morning sunrises would find them running along the Mersey River, wrapped in sweatshirts, with short towels around their necks.
Edward and Stephen studied hard and dreamt positively. Between them, they had a notebook filled with torn tickets of every fencing match they had ever attended. They each had taken part in many elimination bouts (淘汰赛) and had won many gold medals. The difference was in their style.
As fencers, Edward's lean form and long reach made him better in attack, while Stephen's short and muscular frame made him speed y in movement. Whenever they had met in the piste (击剑台), it had always been intense and competitive.
After a series of elimination bouts, they were informed that they were to meet each other in the finals next month —the winner to represent the Club in the Championship Tournament.
Fencing was like any other profession. The two boys knew friendship had nothing to do with it. But how would the competition affect their relationship? Everyday they continued to run together along the Mersey River. However, while joking with each other, they both sensed an invisible wall rising between them.
The day before the finals, they met as usual for their daily workout. After a mile or so, Stephen stopped.
注意:
1. 续写词数应为150左右;
2.请按如下格式在答题卡的相应位置作答。
"I think we both got something to say to each other." Stephen said.
As the two went onto the piste, the audience held their breath.

18、阅读下列短文,从每题所给的A、B、C、D四个选项中选出最佳选项。
How often is your mind quiet? If you're a typical human being, the answer is probably very rarely. For most of our days, our attention is focused on external things—the tasks of our jobs, TV programs, or social media interactions. In the moments when our attention isn't focused externally, it's usually focused on what is called "thought-chatter"—a stream of mental associations consisting of expectations of the future, memories, daydreams, and so on.
But from time to time, we all experience moments when our thought-chatter quiets down, or even disappears altogether. In these moments, we experience a sense of great well-being. We feel a sense of inner harmony. We feel as if we're free of problems, and feel satisfied with our lives as they are.
There are many activities that have the effect of quieting our minds, and so produce a state of well-being.
For example, think about what happens when you go walking in the countryside. You might feel stressed when you start out, but slowly, after-a couple of miles, your mind begins to settle down. The beauty and stillness of nature attracts your attention and you're no longer in your thought-chatter. By the end of the walk you feel almost like a different person. You feel more alive, and much happier—largely because your mind is now quiet.
This is why people love to look at beautiful works of art. When people see the paintings of Monet or van Gogh, they experience a mind-stopping moment, in which they're taken out of their thinking minds and experience a sense of great well-being.
The strange thing is, though, that most of the time this happens unconsciously (不知不觉地). We usually don't associate this well-being with a quiet mind. And we usually don't think of a quiet mind as the aim or result of these activities.
Our estimate of how enjoyable an activity is may depend on its mind-stopping capacity. In other words, the very best performances—and the most rewarding activities—are those which are so attractive and intense that they can completely stop our minds.
I'm not saying that inner quietness is the only reason why we enjoy these activities. Nevertheless, we should certainly become more aware of the association of a quiet mind with well-being. And at the same time we should be aware that it's possible for us to consciously and directly create a quiet mind; rather than as a byproduct of certain activities. And in the end we might develop a permanent quiet mind and attain a state of ongoing contentment and harmony.
(1)、What can be inferred about thought-chatter?A、It requires a lot of practice.C.It might be a talk with a friend. B、It might be unpleasant at times.D.It helps reach a state of silence.(2)、What are the examples of activities mentioned in the text mainly about?A、What activities lead to well-being. B、What can be done to reduce stress. C、How we can make our minds quiet. D、How mental quietness leads to well-being.(3)、How can we determine how much pleasure an activity can give us?A、By judging how much stress it can increase. B、By judging whether it takes place unconsciously. C、By judging to what extent it can quiet our minds. D、By judging whether it associates with well-being.(4)、What does the author intend to highlight in the last paragraph?A、Creating a quiet mind for all time. B、Living a peaceful life permanently. C、Being in harmony with inner quietness. D、Participating in activities for inner quietness. -
19、阅读下列短文,从每题所给的A、B、C、D四个选项中选出最佳选项。
We breathe, eat and drink tiny particles of plastic. But are these in the body harmless. dangerous or somewhere in between? A small study published on Wednesday in the New England Journal of Medicine raises more questions than it answers about how these hits might affect the heart.
The study involved 257 people who had surgery to clear blocked blood vessels in their necks. Using two methods, researchers found evidence of plastics-mostly invisible nanoplastics — in 150 patients and no evidence of plastics in 107 patients. They followed these people for three years. During that time, 30 or 20% of those with plastics had a heart attack, stroke or died from any cause, compared to 8 or about 8% of those with no evidence of plastics.
The researchers also found more evidence of inflammation (炎症) in the people with the plastic bits in their blood vessels. Inflammation is the body's response to injury and is thought to raise the risk of heart attacks and stroke.
"I hope that the alarming message will raise the consciousness of citizens, especially governments, to finally become aware of the importance of the health of our planet." said Dr. Raffaele Marfella of the University of Campania in Italy.
Nevertheless, the study was very small and looked only at people with narrowed arteries (动脉), who were already at risk for heart attack and stroke. The patients with the plastics had more heart disease, diabetes and high cholesterol (胆固醇) than the patients without plastics. They were more likely to be men and more likely to be smokers. The researchers tried to adjust for these risk factors during their statistical analysis, but they may have missed important differences between the groups that could account for the results. This kind of study cannot prove that the plastics caused their problems.
"More research is needed and it is the first report suggesting a connection between microplastics and nanoplastics with disease in humans," said Dr. Philip Landrigan of Boston College. Other scientists have found plastic bits in the lungs, liver, blood, and breast milk, "It does not prove cause and effect, but it suggests cause and effect," he said, "And it needs urgently to be either confirmed or disproven (反驳) by other studies done by other investigators in other populations."
(1)、What did the study find about the plastics in blood?A、They are visible and detectable. B、They may raise the risk of serious injuries. C、They need to be removed by surgery. D、They may account for a higher rate of heart attacks.(2)、What did Raffaele Marfella suggest?A、Immediate action should be taken by government. B、Alarming message should be spread widely and quickly. C、The awareness of the harm of plastic bits should be enhanced. D、Joint efforts must be made to keep healthy physically and mentally.(3)、What does paragraph 5 mainly talk about regarding the study?A、Limitations. B、Advantages. C、Causes. D、Effects.(4)、What did Dr. Philip Landrigan think of the study?A、Helpful but unrealistic. B、Pioneering but impractical. C、Distinctive but unnecessary. D、Suggestive but inconclusive. -
20、阅读下列短文,从每题所给的A、B、C、D四个选项中选出最佳选项。
The new member to the UAE's astronaut training program, the first female Emirati (阿联酋) astronaut, hopes that her mechanical engineering degree will be her ticket to the moon.
Nora AlMatrooshi and her fellow trainee astronaut Mohammad AlMulla were selected from 4000 highly qualified candidates to lead the nation's 9.8 million citizens into space.
The two are looking forward to the laborious 30-month program ahead of them which has already begun with them getting their divers' licences, picking up the Russian language and training for their many media interviews—and will move on to flight and weightlessness school at the Johnson Space Centre in Texas and eventually cruel survival training.
"They will need mechanical engineers to build a base on the moon," says the 28-year-old, who represented her nation at the Mathematics Olympics and worked as an engineer at the National Petroleum Construction Company.
AlMatrooshi says she has dreamed of the stars since kindergarten, when her teacher set up the classroom as the Lunar surface and the five-year-old future astronaut constructed a cardboard moonbase. That early longing to explore space charted her degree choice.
"I actually went after it. I chose to study a degree in mechanical engineering because of a documentary I watched when I was in high school. It was about a group of astronauts going to the International Space Station and the role of the mechanical engineer was highlighted," she say.
Leading big construction projects in the desert has helped equip the daughter of two academics—a PhD father and English teacher mother—for Lunar construction.
AlMatrooshi's fellow trainee astronaut, UAE police helicopter pilot AlMulla, meanwhile says astronaut training has been "a big career change".
"I spent 15 years qualifying to be a pilot, including training in Australia for my commercial pilot's licence," says the father of two. "As a pilot you get used to mastering everything—suddenly I'm changing my path."
"I'm a big fan of SpaceX. The rockets and even the fancy space suits. And hopefully all four of us—and all the astronauts who come after us will get to be a part of future missions—perhaps even to the moon eventually."
(1)、What preparation have they made before the training program?A、They have grasped their native language. B、They have had cruel survival training. C、They have learned to deal with the press. D、They have done some weightlessness training.(2)、Which is the major factor for AlMatrooshi to be a member of the training program?A、She got help from her academic parents. B、She has had a big dream since her childhood. C、She has experience in big construction projects. D、She was the winner of the Mathematics Olympics.(3)、What does the underlined part "I'm changing my path" refer to?A、I'll be a master of life. B、I'm an enthusiast for SpaceX. C、I'm settling my new problem. D、I'm starting a new life from scratch.(4)、Which of the following is a suitable title for the text?A、The fans of Space X B、Dream and achievements C、Passion and preparations D、Future astronaut training program
