2 . Playing sports at school makes people “grittier” and harder working, boosts the chances of achieving long-term goals, and having successful careers, say scientists. The Ohio State University team analyzed National Sports and Society Survey data on almost 4, 000 men and women across the US and asked study participants to rate themselves on a scale of 1-5 on eight statements. They included “I am diligent. I never give up.” And “I am a hard worker”. None of the statements was directly related to sports. 34% of those who did sports as a youngster scored high on the grit scale, compared to 23% of peers who gave up. One in four of those who never played sports ranked low, compared to just 17% of those who did. Lead author Dr. Emily Nothnagle said practicing drills on the field can improve pupils’ lives for decades, adding “The grit they develop from playing sports can help them for the rest of their lives”.
The findings, published in the journal Leisure Sciences, were supported by more sophisticated (复杂的) statistical analyses that accounted for respondents’ demographic (人口的) characteristics. But it appears only children who keep at it-and play continually—get the benefit, say the researchers. Some may just be born with the grit to help them succeed at sports as a young person and then continue to benefit from that trait as an adult. “Quitting could reflect a lack of perseverance, which is a crucial component of grit,” said a researcher. “It could also make quitting an activity, and not persevering, easier the next time.”
Adults who played sports as kids generally perceived the experience helped improve their work ethic, and that perception was linked to their grit scores as adults even though the researchers said people can gain or lose grit throughout life.

3 . Do you want to live another 100 years or more? Some experts say that scientific advances will one day enable humans to last tens of years beyond what is now seen as the natural limit of the human life span.
“I think we are knocking at the door of immortality(永生),” said Michael Zey, a Montclair State University business professor and author of two books on the future. “I think by 2075 we will see it and that’s a conservative estimate(保守的估计).”
At the conference in San Francisco, Donald Louria, a professor at New Jersey Medical School in Newark said advances in using genes as well as nanotechnology(纳米技术) make it likely that humans will live in the future beyond what was possible in the past. “There is a great effort so that people can live from 120 to 180 years,” he said. “Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years.”
However, many scientists who specialize in aging are doubtful about it and say the human body is just not designed to last past about 120 years. Even with healthier lifestyles and less disease, they say failure of the brain and organs will finally lead all humans to death.
Scientists also differ on what kind of life the super aged might live. “It remains to be seen if you pass 120, you know; could you be healthy enough to have good quality of life?” said Leonard Poon, director of the University of Georgia Gerontology Centre. “At present people who could get to that point are not in good health at all.”

4 . Ever walked to the shops only to find, once there, you’ve completely forgotten what you went for? Or struggled to remember the name of an old friend? For years we’ve accepted that a forgetful brain is as much a part of aging as wrinkles and gray hair. But now a new book suggests that we’ve got it all wrong.
According to The Secret Life of the Grown-up Brain, by science writer Barbara Strauch, when it comes to the important things, our brains actually get better with age. In fact, she argues that some studies have found that our brain hits its peak between our 40s and 60s — much later than previously thought.
Furthermore, rather than losing many brain cells as we age, we keep them, and even produce new ones well into middle age. For years it’s been assumed that brain, much like the body, declines with age. But the longest, largest study into what happens to people as they age suggests otherwise.
This continuing research has followed 6,000 people since 1956, testing them every seven years. It has found that on average, participants performed better on cognitive (认知的) tests in their 40s and 50s than they had done in their 20s. Specifically, older people did better on tests of vocabulary, verbal memory (how many words you can remember) and problem solving. Where they performed less well was number ability and perceptual speed — how fast you can push a button when ordered. However, with more complex tasks such as problem-solving and language, we are at our best at middle age and beyond. In short, researchers are now coming up with scientific proof that we do get wiser with age.
Neuroscientists are also finding that we are happier with aging. A recent US study found older people were much better at controlling and balancing their emotions. It is thought that when we’re younger we need to focus more on the negative aspects of life in order to learn about the possible dangers in the world, but as we get older we’ve learned our lessons and are aware that we have less time left in life: therefore, it becomes more important for us to be happy.

5 . The Boy Made It!
One Sunday, Nicholas, a teenager, went skiing at Sugarloaf Mountain in Maine. In the early afternoon, when he was planning to go home, a fierce snowstorm swept into the area. Unable to see far, he accidentally turned off the path. Before he knew it, Nicholas was lost, all alone! He didn’t have food, water, a phone, or other supplies. He was getting colder by the minute.
Nicholas had no idea where he was. He tried not to panic. He thought about all of the survival shows he had watched on TV. It was time to put the tips he had learned to use.
He decided to stop skiing. There was a better chance of someone finding him if he stayed put. The first thing he did was to find shelter from the freezing wind and snow. If he didn’t, his body temperature would get very low, which could quickly kill him.
Using his skis, Nicholas built a snow cave. He gathered a huge mass of snow and dug out a hole in the middle. Then he piled branches on top of himself, like a blanket, to stay as warm as he could.
By that evening, Nicholas was really hungry. He ate snow and drank water from a nearby stream so that his body wouldn’t lose too much water. Not knowing how much longer he could last, Nicholas did the only thing he could he huddled (蜷缩) in his cave and slept.
The next day, Nicholas went out to look for help, but he couldn’t find anyone. He followed his tracks and returned to the snow cave, because without shelter, he could die that night. On Tuesday, Nicholas went out again to find help. He had walked for about a mile when a volunteer searcher found him. After two days stuck in the snow, Nicholas was saved.
Nicholas might not have survived this snowstorm had it not been for TV. He had often watched Grylls’ survival show Man vs. Wild. That’s where he learned the tips that saved his life. In each episode (一期节目) of Man vs. Wild, Grylls is abandoned in a wild area and has to find his way out.
When Gxrylls heard about Nicholas’ amazing deeds, he was super impressed that Nicholas had made it since he knew better than anyone how hard Nicholas had to work to stay alive.

6 . Steve Forest is a scientist. He’s standing on an island off the coast of the Antarctic Peninsula. Below him are several hundred penguins and their children. Forrest’s job is to count every one of them. It's snowing. There is a big wind, too. And their children won’t stay still. Penguins are great climbers. So Forrest and the team members must be too. And penguins aren't always clean.
Forrest has been coming to Antarctica every January for six years. He's helping count the area’s penguins. This will help researchers better understand the Antarctic environment. There used to be lots of penguins in Antarctica, “It's all because of climate change,” Heather J. Lynch says seriously. She is leading the research team. The team member Noah Strycker adds, “We know climate change is hitting the Antarctic Peninsula harder than anywhere else in the world. We are following the situation closely.”
Scientists think that warming waters do harm to krill, the tiny animals that penguins eat. This is bad for the sea life. But krill are hard to study, so researchers pay attention to penguins. They’re easier to follow. They return to the same place each year to lay eggs. If penguins aren't doing well , krill probably aren't either. “Penguins give us an idea about what is going on in the sea around us,” Forrest says.
This year, Lynch’s research team uses a drone to help them. They fly it over an area to take pictures to count penguins.
Counting penguins is quite necessary. The more we learn, the more we know about krill and the ocean animals that depend on them. When we understand them, we can start fixing them. We should consider carefully what Lynch says: “What’s happening in the Antarctic is happening everywhere.”
1. What is required of scientists like Forrest according to Paragraph 1?| A．Being clean. | B．Being good at math. |
| C．Being cool-headed. | D．Being skilled in climbing. |
| A．To protect this animal species from extinction. |
| B．To help find out how many krill might be living |
| C．To have a better knowledge of the Antarctic environment |
| D．To collect first-hand data for analyzing global warming. |
| A．Scientists. | B．Krill. | C．Penguins. | D．Ocean animals. |
| A．Penguins lay eggs in the same place on the island every year. |
| B．The penguin population is increasing due to climate change. |
| C．The penguin population determines the krill population. |
| D．Climate change is most obvious in the Antarctic Peninsula. |
7 . Margot doesn’t have a garbage can. It doesn’t need one because Margot simply doesn’t cause anything to get thrown away. The restaurant doesn’t allow any type of single use plastic. Margot, which opened last year, is one of the small but growing restaurants around the world aiming to avoid not only food leftovers, but also any garbage.
“Food waste has been increasing as an issue for restaurants over the last 10 years,” says Calvin Brown. He runs the Sustainable Restaurant Association. Based in the United Kingdom, the organization helps food business become more environmentally responsible. He says that food waste contributes to releasing the greenhouse gas, so there is strong motivation to reduce waste and help the environment.
In the USA, food waste and packing account for nearly half of the material sent to landfills. Restaurants from McDonald’s to Starbucks are addressing this issue with “no straw Mondays” and limits on single-serving plastic, but a handful of restaurateurs are trying to get rid of rubbish entirely. There’s also economic case to be made for waste reduction. One study shows that restaurants save seven dollars for every dollar invested in anti- waste methods.
Avoiding food waste is the first and perhaps most obvious challenge for sustainable restaurants. Doug McMaster, chef at Silo in London, only serves a set menu. This removes the worry that one particular item won’t sell well, and will spoil in the refrigerator. Compost (堆肥) is a necessity as well. Nolla (meaning “zero” in Finnish) in Helsinki, Finland is giving compost to its suppliers as well as its diners. Nolla also has food- tracking software more commonly used among corporate food service companies to keep track of what sells and what rots.
Sometimes restaurants call themselves environmentally friendly, but they might just be using the label. Calvin offers some pointers on what to look for to make sure a restaurant is truly committed to sustainability.

9 . This could be the perfect gift for the partner, who embarrasses you on the dance floor. Smart socks, which can teach to dance, may be the answer for anyone with two left feet.
The socks have been developed as a running tool to help runners improve their skills. Thanks to the socks, users can accurately record not only how far and fast they run but also how well. It means the user maximizes their performance, and reduces damage to body and prevents hurt. The hi-tech socks are made of special fibers that watch the movements of your feet. They look, feel and can be washed like normal clothes.
Sensors (传感器) record each movement and send it by an ankle transmitter (脚踝发射器) to a smart phone. Then a “virtual coach” application shows the information and can tell the user what they are doing wrong, and help to improve skill in any task with feet.
The socks should be useful to athletes and weekend joggers. “People think running is so easy and of course everybody can do it but not necessarily safely and well,” Dr. Davide Vigano said. A recent study showed that between 60 and 80 percent of runners got hurt per year. This is pretty much more than any other human activity. Researchers say the technology can also be developed to teach people how to dance, play sports such as golf, or even to help to teach women to walk better in high heels.
Mr. Vigano said, “People could all benefit from the idea. We have had interest from all sorts of sports, like skiing, football, cycling and golf. Anything where you have to use your feet can use it. It could even be put in high heels to help women walk in them safely.”
Socks are just the start, and the technology could be used in gloves, hats and boots. The socks, anklet and software package, are expected to be sold for around￡120, which will go on sale in March.

10 . Most 5-year-olds are just learning to read and write but one little girl from the UK has actually written a book that was published in January, 2022.
Bella-Jay Dark from Weymouth is the world’s youngest female to be published and was awarded the title by Guinness World Records. Her book, The Lost Cat tells the story of Snowy, a cat who got lost after going outside alone at night. Bella hopes the book will teach children not to go outside at night alone.
While many adult writers find inspiration for their books from life experiences, Bella’s creative vision actually came from one of her drawings. “It started off as a picture. My dad also agreed I could make a book and a story coming from the picture,” Bella told Guinness World Records.
Bella’s deciding to write a book wasn’t astounding to her mom, Chelsie Syme, who said that her daughter had been writing short stories since age three. Bella spent around five days writing the story and did all of the illustrations(插图) except for one picture that her older sister Lacie May drew.
Syme hadn’t expected the book turned out as well as it did. “I thought it would just be some scribble(涂鸦),” she said. “I didn’t think it was going to go this far. I am so proud and want to see her get the acknowledgement she deserves.”
To earn the Guinness World Records’ title of The World’s Youngest Published Author, Female, the book has to be published by a commercial publishing house and have at least 1,000 copies printed and sold. Bella’s book met the criteria (标准).
Besides being an accomplished author, Bella is just a regular kid who enjoys reading swimming and playing on her tablet. In her free time, she is currently working on a sequel(续集) to Snowy’s story.
1. What does Bella want to tell children in her book?| A．It is not easy to be a story writer. | B．It is dangerous for cats to live alone. |
| C．They should take good care of their cats. | D．They shouldn’t go outside at night alone. |
| A．From a cat’s daily life. | B．From a picture she drew. |
| C．From her father’s advice. | D．From her life experiences. |
| A．Surprising. | B．Embarrassing. | C．Moving. | D．Inspiring. |
| A．She has no sisters. | B．She was born in 2016. |
| C．She will continue to write. | D．She doesn’t like swimming. |
