Yang Jun’ao is a 16-year-old student from No. 1 Middle School in Nanxian County, Hunan Province. He 1 a “lotus root harvesting robot (采藕机器人)”.
“I got the idea after seeing my grandmother in her 70s. She 2 to harvest lotus roots in the hot sun,” Yang said. Sometimes, she would 3 hurt her fingers when using harvesting tools.
To make things 4 for his grandmother, Yang decided to do something. Then, he 5 making a machine that could automatically (自动地) harvest lotus roots. Thanks to his teacher’s 6 , Yang only spent several months building a model of the machine.
When the lotus roots get ripe (成熟的), their leaves turn brown or black. The robot can find ripe roots by looking at the 7 of the lotus leaves. The robot moves on itself through the muddy field. Its arms then 8 the lotus roots perfectly.
“Everything didn’t go well at first. I faced 9 like collecting parts for the model, putting them together and using a hot glue gun for bonding. But practice makes perfect. I made progress and did it well later.” Yang laughed.
When Yang showed the machine to his grandmother, she was happy and gave 10 suggestions for its improvement.
Although Yang still needs to work harder, like finding cheaper ways to make the machines, his teacher, Hong, thought highly of Yang’s creative thinking and spirit to help his hometown.

Brad daydreamed in yesterday’s 21 class and missed the lesson on the Grand Canal (大运河). At night, he found it hard to do the homework on this ancient Chinese 22 . Then he thought of his Sight Pro and put the smart glasses on.
“Teach me about the Grand Canal.” Soon Sight Pro took the boy on a cruise (乘船游览) along the canal, from Hangzhou to Yangzhou.
He was looking at the bustling (熙熙攘攘的) canal banks 23 Sight Pro suddenly said, “Fun time is over. Now comes a test.”
“Hmm, bring it on.”
A question 24 before his eyes: “How long is the Grand Canal Is it over (A) 1,000 km, or (B) 2,000 km ”
“I’ll go for 1,000 km.” It took Brad two seconds to 25 .
“Wrong answer. The Grand Canal is a man-made waterway over 2,000 km, the longest in the world.”
Then came the next question: “When did the building of the canal begin ”
“In the 7th century ”
“Wrong answer. It started in the 5th century B．C．E. (公元前). Then different parts were built at different times. In the 7th century, Emperor Yang of Sui expanded (扩大) the canal to its present size by 26 the parts.”
“How amazing!”
Then came the third question: “ 27 was the Grand Canal built ”
“To make it easier for people to travel around the country.”
“Wrong answer. It was mainly to carry food from the south to the capital in the north. It was also used to 28 goods (货物).”
In the end, Brad scored zero on all the questions, but he was 29 that he had learned a lot. “A big change happened to the Grand Canal during the Yuan Dynasty because the capital was moved to Beijing. Emperors needed new routes,” he wrote the answer 30 one question in his homework easily.

Today, roller skating (滑旱冰) is an easy and fun sport. But many years ago, it wasn’t easy at all. In 1760, a worker named Joseph Merlin 31 it. In his free time, Merlin liked to play the 32 . He was a man with many ideas and many dreams. People called him a dreamer.
One day, Merlin would go to a party. He was happy and 33 . Merlin began to think about how to make a special entrance (入场) at the party. And he thought that he 34 get a lot of attention if he could skate into the room.
Merlin tried different ways to make himself 35 . Finally, he decided to put two wheels 36 each shoe. These were the first roller skate shoes. Merlin dreamed of arriving at the party and 37 into the room while playing the violin. He was sure that 38 would be very surprised.
On the night of the party, Merlin skated into the room, playing the violin. Everyone was really surprised to see him. There was just one problem. Merlin had no way to stop! He kept on skating. Then, with all eyes on him, he hit 39 into a big mirror on the wall. The mirror broke into many pieces with a very loud noise. People laughed 40 remembered Merlin’s wonderful entrance!

It might be strange to wear clothes made from plastic bottles. But in fact, some clothing companies are already making clothes 41 these.
Fashion brand JUMA recently showed its newest collection at a workshop in Shanghai. The jackets, shirts and dresses at the workshop were all 42 recycled plastic bottles.
“We realize that billions of plastic bottles are thrown into landfills (垃圾填埋场) and oceans every year and these 43 take hundreds of years to decompose (分解). We think we should use them to create our 44 and help the environment,” said Alia Juma, the company’s designer.
Many other fashion companies are looking for 45 ways to save our earth these days. The process is rather 46 . First, the plastic bottles are washed and 47 into small pieces. Then they are melted (熔化) and shaped into small 48 . The balls are melted again to form thread (线). People then use the thread to make different kinds of clothes.
According to JUMA, it 49 67,000 bottles to create 1 ton of thread. This reduces water use by 6.2 tons compared with the 50 way of making thread.
“Five bottles can be used to 51 a shirt, 10 a dress, and 20 a short coat,” Juma said.
Some people might have 52 about wearing something made from plastic bottles. 53 according to a report from the science website, clothes made from plastics could be even better than nylon (尼龙) and polyester (聚酯纤维). Plastic thread can be 54 into different materials, such as cotton, silk or even wool. It seems that these clothes may lead to a 55 future of fashion.

Last week, our science teacher talked about food 56 who created popular dishes by chance. She mentioned that one of the world’s most loved snacks— potato chips— was invented by accident in 1853. This story surprised everyone in class, as no one thought such a common snack had an interesting origin (起源).
Long ago, a chef named George Crum worked at a 57 in New York. One day, he was making fried potatoes for a picky customer. The customer thought the potatoes were too thick and sent them back twice. The chef felt a little angry, so he cut the potatoes into very thin slices on purpose, hoping to make them hard to eat. He fried them until they were golden and crispy, then sprinkled a little salt, thinking the customer would 58 them.
But to his surprise, the customer had a taste and 59 the thin, crispy chips. Soon, the snack’s 60 began to spread widely all over the country. More people wanted to try this new 61 . Even today, potato chips remain a favorite snack for many.
My friend said, “This story shows that 62 mistakes can bring big surprises.” I think he has a point. Potato chips not only bring people pleasure when they eat them, but also tell us: sometimes, unexpected things can turn out to be 63 . In class, we were even divided into small groups to share more stories about accidental inventions, like how chocolate chip cookies were made!
Later, our teacher told us another fun fact: the first potato chips were sold in small paper bags, and they didn’t have many flavors (口味) 64 . As time went on, factories started making them in large numbers, so chips became 65 for people to buy. Now, you can find potato chips in almost every supermarket, and it seems that they have become a must-have at parties.

The universe is really mysterious. Scientists have done lots of study about it but there is still much they haven’t discovered.
Scientists think that there 66 life on the earth for many many years. However, we haven’t found life on any other planets 67 . There are eight planets going around the sun. The earth is one of them. There are humans, animals, plants and many other kinds of life on the earth. There is water and air, too. And compared with 68 planets, the earth is not too hot or too cold. None of seven other planets has an environment like that of the earth. The sun and 69 planets are called the solar system, and our solar system is a small part of a much larger group of stars and planets, called the Galaxy (银河系) or the Milky Way. There are billions of stars in the Galaxy, and our sun is 70 one of them.
Scientists have also discovered many other galaxies in the universe. Their light has to travel for many years to reach us. So how large is the universe It is impossible to 71 .
Scientists have sent spaceships to the planet Mars 72 photos. They have even sent spaceships to travel outside the solar system. However, no spaceship has travelled 73 to reach other stars in our Galaxy.
When we see stars 74 the sky at night, we may think a lot: With so many stars in the universe, is there life out there in space If there is unknown life in the galaxy, 75 will life be like there What transports do they use to travel Why don’t they visit us We don’t know the answers.

In our busy lives, it’s sometimes hard to take care of our pets properly. Whether we’re at work or on vacation, it can be difficult to make sure they’re looked after well. To solve the problem, a new pet-caring tool was 76 .
The pet-caring tool helps us take care of our pets even when we’re not around. It has many advantages (优点).
One of the advantages of the pet-caring tool is that it can feed pets without people’s help. We can set the tool to give our pets food and water at certain times, 77 they will never be hungry or thirsty.
Another good thing about the pet-caring tool is that it lets us monitor (监控) our pets’ 78 . The tool can tell us if there’s any 79 activities or if our pets are feeling sad or upset.
The pet-caring tool also 80 our pets safe. For example, the alarm (警报器) will sound if a fire 81 . This way, we know our home and pets are 82 , even when we’re far away.
And the best thing about the pet-caring tool is that it’s very 83 . With just a few 84 on our phone, we can see what our pets are doing, when they’re eating, and how they’re feeling. This makes it easy for us to take good care of them, even when we’re not at home. Besides, it is 85 so everyone can buy it.

Chen Xiaoyu is a student. She is a member of her school’s “Digital Intangible Heritage Team (数字非遗队)”. Their new goal is to 86 the art of making Jiangnan silk lanterns, which is slowly disappearing.
The biggest challenge for Xiaoyu was learning from Master Wang, an 82-year-old lantern artist. He couldn’t teach the detailed techniques of making 87 because of his shaky hands. So Xiaoyu made a decision to use AI to 88 and analyze (分析) his hand movements.
Every weekend, she filmed Master Wang’s hands while he colored silk and bent (把……弄弯) bamboo. The AI program turned his 89 into 368 short videos. When their first digital guidebook was finished, Master Wang was very 90 . “I never thought teenagers would use technology to remember what my old hands forget,” he said.
The team’s big moment came at the Qiantang River Lantern Festival. Visitors could 91 AR glasses to experience Master Wang’s “digital hands”. A 92 girl was very excited and she said, “Now I can learn how to make lanterns without being scared of my hearing problem!”
So far, their online courses have attracted 50,000 people from all over the world. Fans have posted lantern photos 93 apps and gotten lots of likes.
94 Xiaoyu is busy at school, she still practices making lanterns in her free time. “AI won’t take the place of humans,” she tells 95 friends. “It’s like a magic bridge that connects the past and the present.”

Humans have long tried to predict (预测) the weather. From the hunters of ancient times to today’s pilots, predicting rain 96 shine can shape people’s life and make a difference.
In ancient times, the Babylonians tried to predict the weather according to the 97 of clouds. By 300 BC in China, a calendar 98 the year into 24 solar terms (节气) gradually. Each solar term was 99 a type of weather, like the Rain Water (the start of the spring rains), the Waking of Insects and so on. That was 100 for farmers to plan when to plant and harvest (收获).
People used lots of ways to predict the weather over the 101 . You might have heard expressions like “Red sky at night, sailor’s (水手的) 102 ”, which suggests a red sky in the evening is followed by good weather. The science of weather prediction 103 took off in the 1830s with the invention of the telegraph (电报). The next big step came in the 1920s with the invention of the “radiosonde”, a balloon carrying weather 104 high above the ground to collect information.
Today, supercomputers are used to take data (数据) from the world and 105 it very fast to work out the weather. They can predict the weather several days ahead of time.

You’re at your new school. It’s lunch time, but you don’t have anyone to sit with. You want to 106 someone at their table, but you’re not sure if they’re friendly. What do you do
Natalie created an app to 107 the problem. She found it difficult to make new friends and had to search for a new table at lunch every day. If she sat by herself, she felt 108 . But if she asked to join someone and was 109 , she felt embarrassed (尴尬的) .
The app Natalie created called Sit With Us. If a student is having lunch at noon, he or she can create an invitation. Other students can open the app and 110 that invitation. They can then use the app to decide when and where to 111 . This allows students to make 112 online instead of face-to-face.
Natalie is happy to see her app is 113 used by many students, especially those who are suffering from bullying (遭受欺凌) . She won a 114 for the app. She also appeared in many news stories.

The 11-year-old student Wu Zeyin developed a new mobile application (应用程序) called Farm Assistant. With the help of it, farmers in Botswana can make their work much 116 .
Wu, from Hubei province, 117 to Botswana with his family seven years ago. “During the past years, I found there weren’t many fruits and vegetables at local 118 , and their quality was poor,” he said. “Some vegetables aren’t ready to eat and they are quite expensive.”
The weather in this country makes it difficult to 119 plants. For a long time, Botswana had to import (进口) all kinds of fruits and vegetables to meet the needs of its people.
In order to solve the food shortage, Botswana has started to 120 China. In July last year, a project to grow China’s water-saving rice performed 121 in Gaborone, the capital of Botswana. The project brought Wu some new ideas. “At that time, I was preparing for the first Youth Artificial Intelligence and Innovation Competition (青少年人工智能创新大赛),” he said. “When I got the news, I made the 122 to develop an app for farmers.”
The app supports eight crops (庄稼) grown in local areas, 123 tomatoes, potatoes, onions, corn, carrots, cabbages and so on. After planting, the application 124 the farmers what to do at each stage.
Wu used an old 125 in China: “Give a man a fish and you feed him for a day; teach him how to fish and you feed him for a lifetime.”

“Shouguang lies in Shandong Province. It is a city known as the vegetable capital of China”. There, the use of farming 126 is quite common. For example, vegetables grow in water with nutrients (营养液). Screens show the 127 and other information about vegetables’ growing environment.
Liu Pengpeng, a 128 farmer, said, “Thanks to the nutrients, it takes only 28 days for certain vegetables to grow 129 appearing on the market.”
“We also developed a hydroponic container farm (水培器皿农场) by using the hydroponic skills. In it, fresh vegetables can get better living conditions. More importantly, it is a(n) 130 farm. Farmers from other places can buy it and plant vegetables on it just near their homes,” Liu added.
Since the first hydroponic container farm came out in 2017, they have 131 more than 40 farms, mainly to the farmers in countries such as Canada, Russia and Malaysia. They 132 to complete more than 2,000 orders this year.
In the north of Shouguang, the earth has too much salt. It’s 133 for vegetables to grow there. Farmers used to have to grow cotton. They only got 500 yuan from each mu of land. In 2000, they started producing tomatoes by using hydroponic skills. Then their income 134 greatly. Now they can get 60,000 yuan from each mu of land.
Cui, a villager, said, “Science has made our work much easier. And more people can eat fresh vegetables we grow. I’m 135 being a vegetable farmer.”

Chewing gum (咀嚼口香糖) may be one of your favorite sweets. But do you know how it was 136 The inventor of the chewing gum is an American scientist called Thomas Adams. He made it completely 137 .
It was 1869. Earlier that year, one of Adams’ friends showed him an interesting kind of sap (树汁). His friend told him 138 people in Central America liked to chew on it for fun. Hundreds of years passed, people didn’t do that any longer. But Adams was interested in the sap. He wanted to use it to create some new 139 . Adams, however, 140 to create what he wanted. He felt 141 and disappointed and happened to chew on the sap. Surprisingly the sap tasted great. Adams then added something 142 to the sap and started selling it. Later in 1869, he opened a factory 143 produce this delicious treat.
In 1888, Adams gave a 144 to the invention “chewing gum”. The sweet can be got from selling machines at underground stations all over New York City. Over the years, new kinds have been 145 . Now, chewing gum is popular among many people.

During the Spring Festival holiday in 2025, a video of a tourist quickly climbing Mount Tai in Shandong became very popular online. The tourist was trying out a new robot to help him climb. This robot is the first of its kind, 146 it helps people climb mountains without getting too tired. The robot 147 a lot of attention from visitors.
“It really works! Once I put it 148 , I felt like someone was helping me go up the mountain!” the tourist who tried out the robot said. The robot 149 like something from a science fiction movie. It locks around the user’s waist (腰部) and legs to move along with each step. It is very 150 , weighing only 1.8 kg. It uses smart AI technology to understand how the legs are moving and gives the user the right help. This is especially 151 for older people or those who find walking hard. The robot can help the user walk for over 5 hours or travel about 14 kilometers on one charge (充电). This makes it a great 152 for tourists who want to enjoy the natural beauty of the mountain without using the cable car (缆车).
In February, the AI-powered robot was also tested at the Enshi Grand Canyon in Hubei. The Grand Canyon has over 26,000 steps, and the robot helped tourists 153 them easily.
The robot is not just for climbing mountains. It can 154 be used for running, daily walking, and going up and down stairs (楼梯). It can help in many areas of life.
This cool robot will soon be on the 155 . What would you like to use it for

Walking on the streets and seeing different kinds of technology-filled convenient instruments, they are excited and cry out, “Wow! There are so many wonderful things to see that I can’t 194 !” So they stop now and then to take photos and videos. What’s more, all their problems about traveling can be solved by their 195 !
