Among them, the Four Great Inventions played an important role in global civilization (文明). The compass was a great gift to the world from ancient China. Before it was invented, sailors (水手) had to depend on the star to find the right direction. After it was invented, the oceans were open to sail and many discoveries were made with its help. Gunpowder (火药) was one of the greatest inventions. It is said that a Chinese man wrote about how to make it in the third century. At first it was used for making fireworks (烟花). At the end of the Tang dynasty, people began to use it in wars. Before paper-making was invented, the ancient Chinese carved characters (刻字) on animal bones and stones. China was the first country in the world to make it. During the Western Han dynasty, it was made in some places in China and was developed in the Eastern Han dynasty by Cai Lun. Printing was developed in the Song dynasty by Bi Sheng. He carved characters on pieces of clay (黏土) or wood and then brushed ink (墨) on them. After the characters were printed on paper, the pieces of clay or wood could be used again. Later this technology spread to Korea, Japan and Europe. These great inventions not only made China progress but also spread to other countries, helping develop human civilization. They truly show the wisdom of the Chinese nation. 26．What did sailors depend on to find ways without a compass at first? A．The star. B．The sun. C．The moon.

This term, his school held a competition of making a small thing with clean energy. Wang Hao’s group chose to make a solar-powered toy car. They thought solar energy is clean and easy to get. They found a toy car at home, bought a small solar panel (面板) and a few simple parts with their pocket money. At first, they put the solar panel on top of the car and connected the motor (发动机). But when they put the car in the sun, it only moved a little and then stopped. They checked the motor, but it was fine. They tried again, but the car still moved slowly. The group felt a little frustrated—they worried they couldn’t finish the project on time. One of his group members said, “Let’s ask Mr. Zhao for help!” Mr. Zhao looked at their car and smiled, “The solar panel’s angle (角度) is wrong—it’s not getting enough sunlight. You need to turn it a little towards the sun.” The group followed his advice. They also fixed the motor to make sure it connected well to the wheels (轮子). The next day, they took the car to the school playground. In the sunlight, the car ran! It even carried a small toy bear. Finally, their solar car won the Most Creative Prize. When the teacher asked them to share, Wang Hao said, “Learn to ask for help and try again and again!” 31．What did Wang Hao’s group make for the school competition? A．A solar-powered toy train. B．A solar-powered toy car. C．A small robot. D．A paper plane with lights. 32．What does the underlined word “frustrated” most probably mean in English? A．Happy and excited. B．Calm and relaxed.

D．Asking for help and trying again help solve problems. C Do you often forget to drink water between classes? Try the new “Smart Cup”—a water bottle that talks to you! When it glows (发光) green, it means “Good job”. When it turns orange, it’s saying “Time to drink!” It even connects to your phone’s health app. This smart cup acts like a mini teacher. Take a photo of your lunch, and it checks if you need more vegetables or protein (蛋白质). Want to eat ice cream? The bottle might say, “Try yogurt first”. Every Monday, the app shows the intake you drink, like “8L this week”. Drink enough water for 5 days, and you can get a funny cartoon sticker (贴纸) in the app. Chen Kai, a 7th grader from Shanghai, says, “I even get free cookies with enough stickers”. What’s cooler? It turns classmates into health partners. When someone’s cup turns orange, his classmates will say, “Drink up”. School nurse Dr. Chen says, “It’s like having a health teacher in your bag.” But Dr. Li tells everyone, “Your cup can’t do sit-ups for you! Play baseball or jog with friends every day.” Teen Health magazine found 70% of Smart Cup users eat more fruits. “It’s like a game!” says Chen Kai, shaking his glowing bottle. “Now I even finish all the carrots in my lunchbox!” 36．What can we know when the Smart Cup glows orange? A．You have done a good job. B．You should drink water. C．You can connect it to your phone. D．You are having a phone call. 37．What can the Smart Cup help you do? A．Doing sit-ups. B．Playing baseball.

Chinese astronauts on Tiangong Space Station recently shared their special “barbecue” moment, which was a big surprise. The star tool behind this is a new hot-air oven. In the video, astronauts first took out chicken wings and fixed them on special racks. After 28 minutes’ heating, the wings turned golden. Then they baked (烘烤) black pepper steak together, and the delicious smell made them excited. Baking in space is a big challenge. The smoke and oil fumes could have an effect on the station’s air quality. This space oven is not like the ones on Earth. It uses technologies like oil collection and multi-layer filtration (多层过滤), meeting the strict air quality standards of the space station. It can work for more than 500 times for long-term tasks. The oven is part of China’s hard work to make astronauts’ life better. Now there are over 190 kinds of food on the station. The menu changes every 10 days. The “space garden” grows fresh vegetables, adding more nutrition (营养) to their meals. Experts say self-baked food brings not only taste enjoyment but also spiritual comfort (心灵的慰藉) to astronauts living in a narrow space for months. This oven shows China’s progress in space technology and its care for astronauts’ daily life. It’s really a warm gift from Earth to the universe. 根据语篇内容，按要求回答问题。 46．What is the star tool during the “space food live stream”? 47．How long did it take to bake the chicken wings in the space station? 48．What is the big challenge when baking in space? 49．What does the writer want to show us in Paragraph 4? 50．Why can self-baked food bring spiritual comfort to astronauts in space? (不超过15个词) 五、补全对话。(本大题共5小题，每小题2分，共10分) A: Hi. Tony! It’s a nice day, isn’t it? B: Yes, Bill. 51 ? A: To the library. I want to borrow a book. B: 52 ? A: A book about invention.

Among them, the Four Great Inventions played an important role in global civilization (文明). The compass was a great gift to the world from ancient China. Before it was invented, sailors (水手) had to depend on the star to find the right direction. After it was invented, the oceans were open to sail and many discoveries were made with its help. Gunpowder (火药) was one of the greatest inventions. It is said that a Chinese man wrote about how to make it in the third century. At first it was used for making fireworks (烟花). At the end of the Tang dynasty, people began to use it in wars. Before paper-making was invented, the ancient Chinese carved characters (刻字) on animal bones and stones. China was the first country in the world to make it. During the Western Han dynasty, it was made in some places in China and was developed in the Eastern Han dynasty by Cai Lun. Printing was developed in the Song dynasty by Bi Sheng. He carved characters on pieces of clay (黏土) or wood and then brushed ink (墨) on them. After the characters were printed on paper, the pieces of clay or wood could be used again. Later this technology spread to Korea, Japan and Europe. These great inventions not only made China progress but also spread to other countries, helping develop human civilization. They truly show the wisdom of the Chinese nation. 26．What did sailors depend on to find ways without a compass at first? A．The star. B．The sun. C．The moon. D．The wind. 27．Which of the following is TRUE about gunpowder? A．It was invented by a famous scientist in the Tang dynasty. B．It was first used for making fireworks in ancient China. C．It was used in wars around the world in the 3rd century. D．It was the most important invention of ancient China. 28．Where did the ancient Chinese carve characters before paper-making was invented? A．On animal bones and stones. B．On bamboo and silk. C．On leaves and flowers. D．On cloth and wood. 29．What can we learn from Bi Sheng’s printing technology? A．It used metal pieces to carve characters. B．It was invented in the Tang dynasty. C．It only spread to Asian countries. D．Its clay or wood pieces could be reused. 30．What’s the main purpose of the passage? A．To show the value of ancient Chinese culture. B．To introduce the Four Great Inventions of ancient China. C．To compare the Four Great Inventions with modern inventions. D．To explain how the Four Great Inventions spread to other countries. B Wang Hao is an eighth-grade student in Wuhan.
