话题:开发机器人及其促进无化学耕作
What if robots could reduce chemicals and improve soil health? That's what a team of undergraduate engineers from Olin College of Engineering has accomplished with the development of PhoenixBot, a robot that uses artificial intelligence (AI) to autonomously navigate(导航) and weed rowcrop fields with minimal soil disturbance, in what is universally a timeconsuming and laborintensive task for small farms.
The team cooperated with farmers at The Trustees' Powisset Farm, a working communitysupported agriculture farm with over 300 years of agricultural history in Dover, Mass.
“We spent about a month interviewing local farmers, and one of the things that arose from those conversations was the difficulty of weeding, especially on small farms,” said Kenechucwu Mbanisi, Assistant Professor of Robotics Engineering and PhoenixBot team advisor.
“The conventional approach to weeding is to use chemicals, which can be detrimental to crops and has other environmental impacts.We decided to focus on building a robotic weeding system that minimally disturbs the soil and safely uproots weeds around crop plants without the use of chemicals.”
During the yearlong contest, the team engaged with growers about their pain points and challenges and then developed creative solutions using the farmng Amiga robot platform.They used AI, machine learning, automation, coding and fabrication to advance innovation in agriculture.
“Not only does the challenge demonstrate the future of farming with robotics, but it's also encouraging the next generation of engineers to focus their talents on the challenges that exist in growing our food,” said Brendan Dowdle, CEO of farmng.
Founded just twentyeight years ago, Olin College of Engineering has made a name for itself in the world of undergraduate engineering education.The course at the College is designed to provide students with handson experiences and prepare them to make practical change.Students complete dozens of projects over their four years, which prepares them well for the workforce of today and tomorrow.The world needs more engineers, like Olin students and graduates, who care about the planet and engineering a more sustainable future.

话题:“我的学校农场”
The best ideas are often so smart, so simple and so clearly needed; it's strange to discover they don't already exist. So it is with Farm My School, a program that's turning underused land at secondary schools into commercially achievable, regenerative market gardens farmed by and for local communities.
Cofounded by permaculturist Ben Shaw and regenerative educator James McLennan, Farm My School connects local people and organizations through volunteering that helps establish a school's market garden. Students learn about community networks, healthy eating, ecological responsibility, waste reduction and climate relief while helping with food production. Schools integrate all these into their courses while producing vegetable boxes every week that feed local families, supply the school's food needs and ultimately pay the farmer's salary.
Farm My School has gained the extraordinary enthusiasm of the locals, who answered an online shoutout to buy tickets to the program's launch event at Bell Secondary School last October. Called Build A Farm in a Day Festival, the event featured workshops by Ben and James to share the skills required to build what they say is the world's largest nodig garden. “It was such a powerful event, and I think that comes down to people wanting to act now,” says James. “We charged for the experience and 600 guys turned up! They didn't even need free drinks to get excited.We were gardening till midnight. It was amazing. We've got true community buyin.”
Volunteers have since begun beneficial planting throughout the school. Next steps include further discussions with local communities, employing a farmer, and bringing in a teacher to develop courses. “We've seen this huge push towards seeing schools as regenerative spaces, not just for planting but for kids to be more connected to the outside world, and really seeing the school in a whole new light,” James says. “For us, the big excitement is that by allowing a professional farmer to take the responsibility of growing food, it's not only on the school to look after that farm anymore, which eventually makes it much more sustainable,” adds Ben.
5.Why was Farm My School founded?
A.To raise the income of the local people.
B.To advocate a commercial farming plan.
C.To provide free food for local communities.
D.To turn underused campus land into market gardens.
6.How do schools involve students into the program?
A.By developing programbased courses.
B.By organizing voluntary work in communities.
C.By offering them parttime jobs in the market gardens.
D.By encouraging them to produce daily vegetable boxes.
7.What does the underlined word “buyin” mean in Paragraph 3?
A.Competition. B.Investment.
C.Support. D.Protection.
8.What is the highlight of the program according to Ben?
A.It brings in money to support the school.
B.The school farm will be able to last long.
C.The local people will take care of the farm.
D.Students connect more with the outside world.

话题:动植物的杂交条件及结果
You've probably heard of a hybrid(杂交物种)in films or books. The centaurs in the Harry Potter films are hybrids of human and horse. __1__
Hybridization occurs in both plants and animals. __2__ What's more, many plants that people eat, from strawberries to carrots, corn and potatoes, have been created by hybridization.
Crossbreeding(杂交) sometimes occurs when animals' normal territory overlaps(部分重叠). __3__ The grolar bear is a hybrid that happens when grizzly and polar bears mate. As the environment warms, grizzlies in Alaska and Canada wander further north, bringing them into contact with polar bears.
Artificial mixing often happens in zoos,where different species that don't normally meet in the wild can be introduced to each other. Ligers(lion and tiger hybrids) are unlikely to occur in nature, because the only place that their habitats overlap is the Gir Forest in India. __4__ Mixed species are more likely to be born with health issues than other animals. Most hybrids born in zoos are infertile, which means they are unable to have babies. However, many crossbreeds born in the wild, like the grolar bear, can have their own babies.
__5__ “It's part of the evolutionary process,” he says. Fertile hybrids can lead to the creation of a new species and increase the variety of living things.
A.Wildlife conservation is of significance.
B.Did you know hybridization is a biological process?
C.That's due to habitat destruction or changing climate.
D.Did you know that hybrids appear in the natural world,too?
E.Jimmy believes species hybridization in nature is a good thing.
F.Many conservationists think that creating hybrids is a bad thing.
G.Living things,especially plants,will naturally hybridize in the wild.
[语篇解读] 本文是一篇说明文。文章主要介绍了动植物的杂交并且举例说明其发生条件以及结果。
1.D [根据上文“《哈利·波特》系列电影中的半人马是人和马的杂交物种”以及下文“杂交在动植物界都会发生”可知,空处起着承上启下的作用,D项(你知道自然世界里也有杂交物种吗?)符合语境。]
2.G [下文提到许多植物都是通过杂交培育出来的,可知本段主要谈论植物的杂交,G项(生物,尤其是植物,会在野外自然杂交。)中“especially plants”与下文有对应关系,符合语境。]
3.C [根据上文“杂交有时发生在动物的领地重叠的时候”以及下文说到北极灰熊是杂交后代并指出气候变暖可知,C项(这是由于栖息地破坏或气候变化。)中“That's due to”指代上文“Crossbreeding(杂交)sometimes occurs”的发生条件,并引出下文举例说明发生领地重叠的原因,符合语境。]
4.F [下文指出,混合物种出生时有可能带有健康问题,可推断此处是对杂交的消极看法,可知F项(许多环保主义者认为创造杂交物种是一件坏事。)中“a bad thing”与下文“health issues”有对应关系,符合语境。]
5.E [下文提到有繁殖能力的杂交物种可以导致新物种的产生,并增加生物的种类,结合“he says”可知,此处是一个人对杂交的积极态度和看法,E项(吉米相信自然界中的物种杂交是一件好事。)中“a good thing”与下文的“lead to the creation”以及“increase the variety”形成对应关系,符合语境。]

A Journey of Courage
Tom had always dreamed of climbing mountains. As a child, he would spend hours reading adventure books about explorers who scaled the tallest peaks in the world.He admired their bravery and determination, and he promised himself that one day, he would stand on top of a mountain and look out at the world below.
When Tom turned 18, he decided that it was time to make his dream a reality.He spent months training, hiking through forests and climbing smaller hills to build up his strength and stamina(耐力).He read books on mountaineering, learned how to use climbing gear(装备), and practiced tying knots.His goal was to climb Mount Peakstone, a challenging mountain known for its difficult terrain(地形) and unpredictable weather.
On the day of the climb, Tom felt both excited and nervous.He packed his gear carefully—warm clothes, food, water, and his climbing equipment.As he stood at the base of the mountain, he looked up at the towering peak.It seemed much taller in person than it did in the pictures he had seen.For a moment, doubt crept into his mind.Could he really do this?
But Tom pushed the doubt aside.He had come too far to turn back now.With a deep breath, he began his ascent(攀登).The first part of the climb was relatively easy.The weather was clear, and the path was wellmarked.As he climbed higher, the air grew colder, and the wind picked up, but Tom pressed on, determined to reach the top.
About halfway up the mountain, the weather took a sudden turn for the worse.Dark clouds gathered overhead, and snow began to fall heavily.The wind howled, making it difficult to see and even harder to keep his balance.Tom's heart pounded in his chest.He knew he had to make a decision—should he continue climbing, or should he turn back?

[参考范文]
Tom found shelter behind a large rock and took a moment to think. He had read about this in the mountaineering books: when the weather turns dangerous, it's often best to stop and wait it out.Cold and a little frightened, Tom thought of calling for rescue for a moment.But Tom was so close to the top and his dream.He thought, if he had quitted this time, he would feel regretful in his later life.He didn't want to give up now.After a few minutes, he made up his mind.He would continue, but he would be extra cautious.
Step by step, Tom made his way up the mountain, carefully placing his hands and feet on the rock, testing every hold before moving forward. His muscles ached, and the cold cut through his clothes, but he focused on the goal.After what felt like hours, he finally reached the summit.The wind had died down, and the clouds began to clear, revealing a breathtaking view of the world below.Tom stood there, tired and exhausted, but filled with a sense of accomplishment.As he looked out at the vast landscape, he realized that the journey had taught him more than just how to climb a mountain.It had taught him the importance of perseverance, courage, and believing in himself, even when things seemed impossible.The mountain had tested him, but in the end, he proved to himself that he was capable of achieving his dream.
[语篇解读] 本文以人物为线索展开。讲述了Tom从小就有着登上高山的梦想,为此他苦练自己的体力和耐力,阅读有关登山的书籍和人物故事,为自己登上高峰做了充足的准备。当他最终去登山时,一开始很顺利,但到达半山腰时天气变得恶劣,迫使他停下来思考是继续攀登还是就此停下来。
[详解]
1.段落续写:
①由第一段首句内容“汤姆在一块大岩石后发现了一处躲避处,他躲在那儿思考着。”可知,第一段可描写汤姆的内心活动,到底是继续攀登还是请求救援放弃登山。由第二段的首句可知,在第一段的后面一定是汤姆坚定信心继续登山。
②由第二段首句内容“汤姆极其谨慎地攀登。”可知,第二段可描写汤姆登山的艰难过程以及他如何克服困难到达山顶,最后要有感而发,呼应文章主题。
2.续写线索:
汤姆向往登山——汤姆为登山做好各方面准备——开始登山——途中遇挫——决定克服困难继续攀登——艰难登上山顶及感悟
