In a long-sleeved shirt and jeans, Dieudonne Twahirwa looks nothing like the traditional African farmer. The 30-year-old owner of Gashora Farm knows what a difference that makes.
"You need more role models," he said, standing among knee-high rows of chili (辣椒) plants. "If you have young farmers, they have land and they drive to the farm and others may think, ‘Why can't I do that?"
Twahirwa, a university graduate, bought a friend's tomato farm six years ago for $150. He made $1,500 back in two months. "You have to link farming with entrepreneurship (創(chuàng)業(yè)精神) and real numbers," he said.
Many young Africans are quitting countryside areas, choosing not to work hard for a long time in the fields-a job made a lot tougher by climate change. But Twahirwa is one of a growing group of successful farmers working to improve agriculture's image on the continent. Some 1,000 farmers now produce chilies for him. He is starting a fourth farm of his own, and exports fresh and dried chilies and oil to Britain, the United States, India and Kenya.
Africa has the world's youngest population and 65 percent undeveloped farmland. Yet accessing land and loans is difficult, and African productivity is low with crop output just 56 percent of the international average.
"Agriculture is mainly connected with suffering and no young person wants to suffer," said Tamara Kaunda, an expert of FAO. She believes African agriculture needs a change to get rid of its old-fashioned image of extremely difficult and tiring work with a hoe (鋤頭). "Show young people with tractors, green fields, nice irrigation systems and smartphones," she said.
Getting young people involved in agriculture does not mean they have to work on a farm. For example, in coffee production, the beans go from the farm to the washing station, then to be separated from the outer coverings. There are people in the coffee value chain who just build washing stations and rent them out. You just have to find a place to plug in.
Walk in London's cobblestoned streets, cross centuries-old bridges and wander through covered markets — before the morning drizzle (毛毛雨) has given way to afternoon sun, history will become alive before you. The city's old buildings, black taxis and red double-decker buses all have long and complicated stories that are deeply rooted in London's traditions. So do fish and chips. Apart from being a fast-food favourite, fish and chips are also typically served as a Friday meal, in schools for lunch and at home for dinner. Former British prime minister Winston Churchill famously called fish and chips "the good companions".
More than 229 million portions of white fish fillets are sold each year in England, each one coated in a light batter (面糊) and deep-fried, and served alongside fat fried slices of potatoes. For many English people, fish and chips are best served wrapped in newspapers and wolfed down with a combination of a wooden fork and greasy fingers, preferably seaside.
Most historians agree that it was in London, not on the coast, that the first fish and chip shop opened its doors. It was here too that the city's working class pushed the dish into popular cooking culture. And it is in London that one of the oldest surviving chippies still stands today.
This is an understandable source of despair for nutritionists: Fish and chips may contain an abundance of vitamins and minerals, but both main ingredients are also deep-fried in oil that often contains unhealthy saturated fats. For all its traditional popularity, however, according to a 2016 study by the U. K. Department for Environment, Food and Rural Affairs, fish and chips consumption has lost significant market share in recent years to other takeaway items such as pizza and kebabs.
A group of small, waggling (扭動(dòng)) robots that communicate by flashing lights can make collective decisions. This is similar to the process bees use to reach an agreement on where to build their nest.
"We believe that in the near future there are going to be simple robots that will do jobs that we don't want to do, and it will be very important that they make decisions on their own," says Carmen Miguel at the University of Barcelona in Spain. She and her team tested how copying bees might help with that.
When bees go house-hunting, they communicate their preferred locations through a "waggle dance". The more a bee recommends one location, the longer and harder it waggles. Eventually other bees join them, and they reach an agreement when a majority are waggling together. Researchers previously translated this behavior into a mathematical model, and Miguel and her colleagues used it to program decision-making rules into small robots called kilobots.
Each kilobot with three thin legs had an infrared-light emitter (紅外線發(fā)射器) and receiver, and a colored LED light. Within a group, kilobots could move around, turn clockwise or anticlockwise and use infrared signals to exchange information.
Ezequiel Ferrero at the University of Barcelona says that across all the experiments, kilobots reached an agreement within about half an hour, even when they didn't have many immediate neighbors to communicate with. He says that getting the right combination of how long they spend transmitting their message and how much they walk around allowed them to make a collective decision in the end.
As the world struggles to deal with the climate crisis, some companies are working to remove polluting carbon dioxide (CO2) from the air. , but two US companies have recently made important progress.
Scientists say large amounts of CO2 must be removed from the atmosphere and stored. . But there's so much CO2 in the atmosphere that just planting trees and protecting forests won't solve the problem. In addition, when plants and trees die, the carbon they've stored gets released again.
That means humans need to come up with ways of removing carbon from the air and storing it. This is called Direct Air Capture (DAC). The science of removing carbon from the air is challenging, and it's still pretty new. Most DAC processes require a large amount of energy, .
A company called Heirloom has just opened the first DAC plant in the United States. The company heats up the limestone (石灰?guī)r)to separate out the CO2, which is then locked away in concrete (混凝土). The process is extremely expensive. . That's a tiny amount compared to how much carbon needs to be removed from the atmosphere, but the company says it hopes to remove a billion tons per year by 2035.
. Some people worry that it will take too long for DAC technology to become powerful enough to make a difference. Others worry that focusing on removing carbon could take attention away from more important climate actions, like switching from fossil fuel s to renewable energy. But experts say the decision isn't to do one or the other. The world needs to end fossil fuel use and pull carbon out of the air.
A. It's a huge and challenging goal
B. Plants and trees can do this naturally
C. Everyone is not excited about carbon removal
D. The new plant can remove 1,000 tons of CO2 year
E. Graphyte is another US company working on DAC
F. and CO2 is just a small part of the gasses that make up air
G. so one puzzle for these companies is how to remove carbon without creating more pollution
I grew up hiking and climbing mountain s a lot. It was my dad who accompanied me and taught me how to hike and climb mountains. On our first hike, our group ran ahead without us. Dad and I ended up 1 the path toward the top. This was the 2 part of the climb, where we had to climb rocks. I was scared not to have the path to tell us where to go. Mainly, I was afraid that Dad would fall off the mountain when he went 3 to seek for the best way for me to climb up. I was grateful for his 4 . He always made me feel like I was safe with him — even when he insisted that we should not 5 .
When we were close to the top, we 6 some hikers. One of them crouched (蹲) down on a rock, grasping at branches of a bush. His face was 7 and looked frozen, like a statue. Dad asked what was going on. The man 8 told him that he was frightened of 9 . In my 7-year-old mind, I thought, "But, you're climbing a mountain!" Dad always helped people in trouble. He told the man to 10 him while he led him to a spot below that was 11 by trees, with no view of the valley below. Dad told him to wait there for his group of hikers to come back and 12 him up. Dad taught me sympathy and to help others in need whenever I can.
When we finally reached the top and 13 our group, we sat on the highest point, looking at the breathtaking scenery. I was so 14 we hadn't stopped halfway. Dad taught me, "Don't give up, especially when you're almost there." This has been a valuable 15 that has got me through some big challenges in my life.
Dominic Richard loves cycling. In 2023, he ordered a new bike from a factory in Shanghai and flew there (pick) it up in person. However, followed was jaw-dropping. Instead of flying back, he determined to ride back alone to the UK.
Richard cycled through cities and countries, taking in the sights along the way. He started in Shanghai, where after successfully picking up his new bike he began the journey. Considering all the possible challenges, he travelled light. The bike (equip) with a carbon frame and tubeless tires, meaning no worry about a flat tire on route. He had a sleeping mat that kept him (comfort) at night and bags to pack his clothing and equipment in. Battling a burning heat wave, he cycled across the vast expanse of China, often resting by the side of the road. People were curious his journey along the way. Now and then Richard got (invite) to many natives' houses for free lunch and supplies, with truck drivers and cyclists (stop) him along the road to chat.
Fortunately, after the (impress) long ride, Richard made to his home in the UK. "Thanks to this experience, I got better understanding of amazing China and found a better self."

Dear Allen,
Yours,

Dora Kellert was the school's spelling bee champion, winner of the reading contest at the public library three summers in a row and the playground grand champion in chess. She was a straight-A student.
Though Dora was talented, she was no good at sports. She could not figure out in which direction to kick the soccer ball. She was no good at baseball or basketball either. It wasn't until last year, when she was eleven years old, that she learned how to ride a bike. And even then she had to use training wheels.
"I'll never be good at sports," she thought one day as she lay on her bed staring at the shelf her father had made to hold her trophies (獎(jiǎng)杯). "How I wish I could win something, anything, even marbles (彈珠)."
At the word "marbles," she sat up, "That's it. Maybe I could be good at playing marbles." She jumped out of bed and found a can full of her brother's marbles. "Yes," she thought. "I could play marbles, and marbles is a sport." At that moment she realized that she had only three weeks to practice. The playground championship was coming up. She had a lot to do.
To strengthen her wrists (腕關(guān)節(jié)), she decided to do twenty push-ups on her fingertips, five at a time. By the end of the first set she was breathing hard. She did one more set and decided that was enough push-ups for the first day. She squeezed (握) a rubber eraser one hundred times, hoping it would strengthen her thumb (大拇指). This seemed to work because the next day her thumb was painful. She could hardly hold a marble in her hand, so Dora rested that day and listened to her brother's tips on how to shoot.
After school the next day she practiced three hours straight. After practice, she squeezed the eraser for an hour. Practice, practice, practice. Squeeze, squeeze, squeeze. Dora got better and even beat her brother for the first time.
