1 . Common Mistakes New Runners Make
Running is a great way to get in shape and just about everyone can do it. However, many make a number of common mistakes, which can interfere (妨碍) with training or lead to injury.
·Doing too much too soon
One of the biggest mistakes new runners make is doing too much too soon. Slowly easing into a training program will help reduce the risk of injury, so you can continue on with your new running routine
·
Beginners might think they need to run every day (or nearly every day) to meet their fitness or weight-loss goals, but this couldn’t be further from the truth. Running is a high-impact activity which can be really hard on your body. So it’s important to give your body a rest between workouts.
·Not wearing the right equipment
•Running through pain
| A．Not taking rest days |
| B．If you’re just starting out |
| C．Comparing yourself to others |
| D．Running can be uncomfortable at times |
| E．It’s important not to use the same muscles |
| F．While it may be true that you don’t need expensive equipment to take up running |
| G．Experts suggest increasing your running distance by no more than 10% each week |
2 . With almost all big employers in the United States now using artificial intelligence (AI) and automation in their hiring processes, the public is considering some urgent questions: How can you prevent discrimination in hiring when a machine is keeping the discrimination? What kind of methods might help?
Some 83% of employers, including 99% of Fortune 500 companies, now use some form of automated tools as part of their hiring process, said the Equal Employment Opportunity Commission’s ( EEOC) chair Charlotte Burrows, at a hearing on Tuesday. She said everyone needs to speak up on the debate over these technologies. “The risks are simply too high to leave this topic just to the experts.”
Last year, the EEOC issued some guidance around the use of cutting-edge hiring tools, noting many of their shortcomings. The agency found that resume( 简历) scanners which prioritize keywords and programs which evaluate a candidate’s facial expressions and speech patterns in video interviews can create discrimination. Take, for example, a video interview that analyses an applicant’s speech patterns to determine their ability to solve problems. A person with a speech problem might score low and automatically be screened out. The problem will be for the EEOC to root out discrimination or stop it from taking place.
The EEOC is considering the most appropriate ways to handle the problem. It’s agreed that inspections are necessary to ensure that the software used by companies avoids intentional or unintentional discrimination. But who would conduct those inspections is a more challenging question. Each option presents risks, Burrows pointed out. A third party may turn a blind eye to its clients, while a government-led inspection could potentially stop innovation.
In previous remarks, Burrows has noted the great potential that AI decision making tools have to improve the lives of Americans, but only when used properly. “We must work to ensure that these new technologies do not become a high-tech pathway to discrimination,” she said.

| C．Stop using AI in hiring processes. | D．Watch debates about technologies. |
| A．By scanning keywords. | B．By evaluating resumes. |
| C．By analyzing personalities. | D．By assessing speech patterns. |
| A．High expense. | B．Unfair results. |
| C．Age discrimination. | D．Innovation interruption. |
| A．Favourable. | B．Disapproving. | C．Cautious. | D．Doubtful. |
3 . At Sho Farm in northern Vermont, farmers Melissa Hoffman and Shawn Smith work hand in hand with the land and its inhabitants, and among them are hundreds of ducks. The ducks at Sho Farm are not being raised to be killed for food. Rather, they are naturally involved in farming operations, helping to manage pests and add fertilizer (肥料) to the soil.
In the beginning, Hoffman, who has a background in organic farming and ecology action, worked with ecologists and biologists to survey the plants and wildlife all around the area. This was “to understand who was living here, so that everything we did was in relationship to the life already here,” he says.
So, at Sho Farm, focus is placed on living harmoniously alongside other life and working with traditional ecological knowledge. Food is seen not as a commodity (商品) but as a relationship with land and life.
The methods of food production at Sho Farm, as well as the farmers’ philosophy of working with rather than against nature, are in sharp contrast to most modern agricultural systems. And that’s the point. “We’ve been talking a lot about the broken food system and the consequences of it to the environment, to wildlife, to the animals in animal agriculture and to human health,” says Hoffman, adding that it’s not just the food system that’s broken. “It’s the relationship between humans, non-human animals, land and nature.”
The ducks play a vital, integrated role on the farm, explains Hoffman, by naturally providing pest control, fertilizer and (fuel-free) land maintenance (维护), just as by-products of their existence. “We noticed where we summered groups of ducks and parts of the food system that were not doing very well. The following year, the food system was efficiently improved,” he says.
It’s a symbiotic relationship that works well. “Animals don’t have to be part of a farm in a commodity sense. They can be part of the farm as a partner,” Hoffman says. “They are wonderful partners.”
1. Why did Hoffman do a survey in the beginning?| A．To get familiar with the surroundings. |
| B．To have a good relationship with other people. |
| C．To live in harmony with other life on the farm. |
| D．To have a good understanding of organic farming. |
| A．The causes of the broken food system. |
| B．The reasons for Hoffman’s farming methods. |
| C．The changes in modern agricultural systems. |
| D．The process of food production at Sho Farm. |
| A．Animals are treated well at Sho Farm. |
| B．Animals are not to be sold for money. |
| C．People and animals play the same role in organic farming. |
| D．People and animals work together and benefit each other. |
| A．Efficient. | B．Modern. | C．Natural. | D．Economical. |
4 . New research led by scientists at the University of Massachusetts Amherst has revealed that the spiny pollen (带刺花粉) of plants in the sunflower family can reduce infection of a common bee parasite (寄生生物) by up to 94 percent. The sunflowers'spiny pollen can destroy a parasite called C. bombi (熊蜂短膜虫), which has been significantly reducing bumblebee populations.
To investigate how sunflowers help bumblebees resist C. bombi, the researchers separated the spiny outer shell of the pollen from the chemical metabolites (代谢物) in the pollen’s core. They then mixed the spiny pollen shells of sunflowers, with the chemistry removed, into the pollen fed to one group of bees.
Another group was fed wildflower pollen with sunflower metabolites and no sunflower shells. The researchers discovered that the bees that ate the spiny sunflower pollen shells had the same response as bees feeding on whole sunflower pollen. These bees had a markedly reduced risk of C. bombi infection compared to those fed sunflower metabolites.
Bumblebees, which are vital pollinators of crops and wildflowers, are experiencing a rapid decline in their populations worldwide. Habitat loss due to urbanization and agricultural intensification is the greatest threat to bumblebees. Climate change is also taking a toll on bumblebees. As temperatures rise, bumblebees are forced to move further north to cooler climates, which can affect their ability to find food and nesting sites. Pesticide use is another significant threat to bumblebees. These chemicals are harmful to them and can damage their navigation and immune systems, leading to reduced reproductive success. Bumblebees play a vital role in maintaining healthy and diverse ecosystems. Understanding how sunflowers protect bees from disease could help us identify other flowers that have similar protective properties. Through this, researchers can work towards developing new strategies to help conserve bumblebees.

5 . Three months after Hurricane Katrina in 2005, Rebecca Sell, then 24, a photojournalist for Fredericksburg photographed a New Orleans couple worriedly examining water-spotted photo albums. As she took the photo, something within her clicked. “I told them I could take the ruined pictures, copy them and give them digitally restored photos,” she recalls. Although a bit sceptical, the couple agreed. Rebecca took their photos home, restored them and took them to the couple at their temporary home. “It felt so good to be able to do that for them,” says Rebecca.
When her editor, Dave Ellis, saw the photo of the couple, he suggested they go back and restore damaged photos for even more people. So in January 2006, with paid time off from the newspaper, the two set up a shop in Pass Christian. After posting a notice in the community newsletter, Rebecca and Dave received 500 photos in four days. For each, the pair took a new digital picture, then used high-tech software to erase water spots and restore colors. It just so happened that a popular website linked to Dave’s blog about the experience, and soon Operation Photo Rescue, as it came to be known, had emails from hundreds of volunteers, including photographers and restoration experts, eager to help.
Though the digital restoration is a painstaking process, mending irreplaceable family pictures means the world to victims like Emily Lancaster, 71, who took out piles of ruined photo albums after Katrina, never thinking the mess could be saved. But she just couldn’t bear to part with a few treasured pictures, including a portrait of her father, who had passed away, and a photo of her husband as a boy. Then she heard about Operation Photo Rescue. “I didn’t have a whole lot of hope they could fix them, but they did,” Emily says. “Almost every day I think about all the pictures I’ve lost. I’m so happy to have these two.”
In the five years since Katrina, Operation Photo Rescue has collected thousands of pictures ruined by floods, hurricanes and tornadoes. Volunteers make “copy runs” to disaster areas across the country to gather damaged photos from survivors; operating costs are covered by donations. “It’s great to be able to give people some of their history back,” says Rebecca. “One person told me that thanks to us, her grandmother got to see her photos again before she passed away. Moments like that remind me why I do this.”

6 . Humans are pretty unique among life on Earth. As far as we know, we’re the only living species to evolve the higher intelligence, wear clothes, cook our food, and even invent smartphones. But what if humans suddenly went extinct? What other animals might evolve to have the smarts and skills to create large,complex societies as we have?
With modern genetic technology and our understanding of evolution, “we’re pretty good at making short-term predictions. “Martha Reiskind, an ecologist, told Live Science. For example, we can predict that if humans were to disappear tomorrow, climate change would continue to drive many species to adapt to drought. And species living in cold areas would continue to struggle to live as well.
“A big thing will be the concept of convergence.” Dougal Dixon, a geologist, told Live Science Convergence is an evolutionary process by which two unrelated creatures develop similar features in order to succeed in a particular environment. For example, with their sleek (光滑的) bodies and fins, fish are suitable for living in water. However, dolphins have evolved a very similar body plan—and unlike fish, they are warm-blooded, air-breathing animals with a totally different evolutionary background.
One feature that makes humans uniquely good at building is our skillful hands. In order to fill the same role as humans—that is, building cities and heavily modifying our environment—another species would need to develop a similar ability to control objects. Other primates (灵长目动物), like chimpanzees. our closest living relatives, already can make tools in the wild. It’s possible that if humans disappeared, they might replace us.
But any disaster terrible enough to destroy humans is also likely to destroy chimpanzees, which leaves another tool-using candidate to fill humans place: birds. Birds are very brainy. Some birds can use their feet to form wire into hooks. And trained African grey parrots can learn upwards of 100 words and do simple math, including understanding the concept of zero. Birds can also gather in large groups, and some even build group nesting sites.
Of course, all of these are predictions. Scientists have said it’s almost impossible to truly predict how evolution will unfold. As we go further and further out, the prediction is less accurate. And it’s even more difficult to predict whether another species will develop human-level intelligence, Some think that it could happen. Others, however, are less optimistic because they don’t think nature will make mistakes twice.

7 . Chinese ancient poetry was the heart and soul of Chinese ancient literature. Poems and songs have been the means of entertainment of men from the earliest times. Chinese ancient poetry was primarily written to be chanted or sung.
The poetic persona (表面形象) is a feature of classical Chinese poetry. The persona appears when the poem is written from the viewpoint of some other person. Some poems are comments on the contemporary society and life. Chinese ancient poems, although apparently simple in the first reading, have deeper and greater meanings when read intensively.
The earliest Chinese ancient poetry begins with The Book of Songs which is a collection of 305 poems. It was the first comprehensive compilation(辑)of Chinese ancient poems. Each poem in The Book of Songs was set to music and could be sung. Folk songs made up the most part of the book! Confucius, the great ancient philosopher, was fond of this book. It was also the accepted textbook of the Confucian school.
Chinese poetic history is extremely long and colorful. The Tang dynasty, the golden age of Chinese ancient poetry, produced many famous poems. Three Hundred Poems of the Tang Dynasty, was compiled by Heng Tang Tui Shi(蘅塘退士) of the Qing dynasty. This was used for very many years to teach primary students.
Almost everything is the subject of Chinese ancient poetry including marriage, agriculture, courtship(求爱), sorrow and joys, romance, heroic deeds and so on. Generally, each poem is usually composed of lines of four, five or seven syllables. Translations of Chinese ancient poems are available in books and also online. Now these beautiful poems have attracted readers all over the world.
1. What’s the earliest Chinese poetry intended to do?| A．To record history. | B．To spread knowledge. |
| C．To entertain people. | D．To state people’s thoughts. |
| A．Modern and symbolic. | B．Simple but meaningful. |
| C．Difficult and figurative. | D．Imaginative but unreal. |

8 . The evolution of butterflies continues very fast. Species with larger wingspans(翼幅) have expanded their range in high-latitude parts of North America as the climate has warmed, while smaller butterflies and those adapted to cold conditions have tended to decline.
Vaughn Shirey at Georgetown University in Washington DC and his colleagues built a computational model to analyse the presence of 90 butterfly species above 45 north in North America from 1970 to 2019.
The team analysed how shifting monthly minimum temperatures over the past 50 years may have affected the ranges of butterflies.
The monthly minimum temperatures increased by 0. 86℃(1. 5°F), on average, across the study region from the 1970s to the 2010s. As temperatures rose, butterfly species with larger wingspans were more likely to spread out into a greater proportion of the study region. But for smaller butterflies, rising temperatures were linked with a a smaller number in the area over which they were found.
“It seems logical to assume that, if species with larger wingspans have the capacity to better travel to new suitable habitats, it gives those species an advantage in a changing climate,” says Yoan Fourcade at the Institute of Ecology and Environmental Sciences in Paris.
Butterflies adapted to warmer temperatures also seemed to have dispersed(分散) more across the study region than those adapted to colder climates.
Climate change has been linked with a fall in some butterfly species, including the monarch （Danaus plexippus）in North America. But some appear to be adapting: a 2022 study found that British butterflies are steadily getting bigger in response to rising temperatures.

9 . When 16-year-old Grayden Brunet joined the Sackets Harbor, New York, volunteer fire department in 2017, he was the youngest on the team by 20 years. He was so excited to be following in his dad’s footsteps that he persuaded two classmates, Niklas Brazie and Dalton Hardison, to sign up too.
A few years later, the older firefighters quit their jobs over COVID-19 concerns. Suddenly, the three teens not only were helping the Sackets Harbor volunteer fire department, they were the Sackets Harbor volunteer fire department. They were the ones responding to heart attacks, car accidents, and suicides. They were the ones sending COVID-19 patients to hospitals.
“We went from not even having our licenses to saving people’s lives,” Hardison told CBS.
As far as the teens were concerned, they couldn’t quit. If they did, Brunet told North County Public Radio, “The community would lose the ambulance.”
The three teens struggled on alone for a year until help arrived in the form of five more teens, all motivated to serve their neighbors in the town of 1, 300. “When they call 911, they’re expecting someone to help them,” says Sophia DeVito, who was 16 when she joined.
The job is taxing. One night last fall, the crew responded to two ambulance calls and a fire. They got home at 5:30a. m., just two hours before school started.
“It’s definitely hard coming back from the calls and having to take a math test,” Grayden’s younger brother Gannon told WWNY.
But they don’t mind the hard work. And the looks on the faces of 911 callers when they meet their rescuers? Priceless, says Cooper Antonson. “A lot of people ask, ‘Wait, how old are you?’”
1. Why did Brunet join the Sackets Harbor volunteer fire department?| A．Because people expected him to help. |

10 . In a study, published in the journal Proceedings of the Royal Society B: Biological Sciences, a team of French researchers at the University of Sorbonne Paris North demonstrated that ants have the potential to act as early stage cancer detectors.
“We knew that ants can be easily trained,” Baptiste Piqueret, who led the study, said. “Furthermore, they have an efficient sense of smell. We then combined these two abilities and tested whether ants were able to detect the smell of cancer or not.”
Tumor (肿瘤) cells produce specific chemical compounds that allow them to be distinguished from healthy tissues. These are known as cancer biomarkers. Animals can be trained to sniff out (嗅出) these chemicals and thus identify when a patient has cancer.
In the present study, worker ants of the species Formica fusca — commonly known as the silky ant —were trained to recognize cancer biomarkers of an extremely aggressive human breast cancer. The urine (尿液）of mice carrying these tumors was collected and presented to the trained ants, alongside urine from tumor — free mice.
After just three rounds of training, where the ants learned to associate the smell of cancer biomarkers with a sugary treat, they spent approximately 20 percent more time near the urine from the tumor - bearing mice than the urine from those who were tumor-free.
In the past, dogs and mice have also been shown to sniff out cancers. But ants would provide a particularly attractive alternative as they are relatively easy to keep, they don't require expensive rearing (饲养) facilities, and it appears that they can be trained to recognize specific odors in relatively few trials.
