They had to use fire 1 nature, like when lightning struck trees or volcanoes erupted (火山爆发). Fire was very special to them, because they had to wait for days 2 even weeks to get it back if it went out. But a clever man named Suiren changed everything. One day, he saw a woodpecker (啄木鸟) pecking at a 3 (die) tree. Every time its sharp beak (喙) hit the dry wood, tiny sparks (火花) flew out. “Wow”, he thought. “Maybe I can make fire like that!” He decided to try rubbing (摩擦) wood together. First, he found two dry pieces of wood. He cut 4 into a round stick and then made a small hole in the other. Then he put the stick into the hole 5 (care) and rubbed as fast as he could. His hands got 6 (tire), but he didn’t give up. After trying many 7 (time), the wood started to smoke and get hot. Suddenly, the dry wood chips caught fire. Later, Suiren’s method of making fire 8 (spread) widely. It helped people to stay warm, cook food and scare away wild animals. Suiren’s story 9 (be) told for thousands of years. It tells us how important it is 10 (keep) trying. “Drilling wood to make fire” isn’t just an old story—it shows how humans used their brains to make life better. 二、选词填空。 请从方框内选择适当的词，并根据需要用其正确形式填空，使文章语法正确、完整连贯，请将答案写在答题卡对应题目的答题位置上。注意：每空一词，每词仅用一次，有两词为多余项。 great  improve  something  thing  spread  common  other  another  lost  but  for  to The Four Great Inventions of Ancient China The Four Great Inventions of ancient China show Chinese people’s creative and wise minds.

The new technology was developed by a team from Peking University and City University of Hong Kong. What makes this chip special is its ability to cover a really wide frequency band (频段)—from 0.5 GHz to 115 GHz. This means a single chip can deal with information that used to require 3 to 5 different pieces of equipment. Its processing speed can reach over 120 GB per second, fast enough to download several high-quality movies in just 1 second—think of downloading 3 or 4 movies you love in a blink, even those with clear pictures and loud sound! What makes this chip even more excellent is its intelligence (智能). It can explore which frequency bands are crowded and change to spare ones by itself. This makes sure the signals (信号) are stronger even in awful environments, like busy streets with too many phone signals, so you won’t lose your video chat with friends easily. The breakthrough means that future 6G networks are expected to support uses such as remote operation (like controlling robots to do small factory jobs from far away) and VR shopping or visiting, as well as connections from the deep sea to outer space. This progress shows China’s development in communication technology and brings us one step closer to the 6G age. 1．Who developed the record-breaking chip for 6G communication? A．A team from Peking University and City University of Hong Kong. B．A team only from City University of Hong Kong. C．A team only from Peking University. D．A team from an American university. 2．How does the writer explain the chip’s ability in paragraph 2? A．By telling reasons. B．By giving examples. C．By listing numbers. D．By asking questions. 3．Why is the chip’s intelligence excellent in Paragraph 3? A．It can only work in quiet environments. B．It needs people’s help to change frequency bands. C．It stops working when there are too many phone signals. D．It can find crowded frequency bands and change to free ones. 4．What can we know about future 6G networks from the passage? A．They need 10 seconds to download one movie. B．They may let people control robots in the deep sea. C．They will never lose your video chat with your friends. D．They can only be used on the ground of the earth but outer space. 5．What is the best title of this passage? A．The Development of 6G Technology in Our Daily Life B．A New Chip and Its Role in 6G Communication C．Chinese Scientists and Their Research Teams D．How the Scientists Developed a New Chip （2026·江西·中考真题）HIGH-FLYING HELPERS Drones, created as tools of war at first, are now performing important tasks to help people around the world. Sending medical help to hard-to-reach places has been a problem for years. In Rwanda, some small hospitals don’t have enough medicine. As a result, many people die. A local company is trying to use drones to solve this problem. Drones can quickly provide healthcare service to the hospitals around Rwanda, and more people receive life-saving medicine. Drones also help after natural disasters. In 2015, a heavy storm hit Vanuatu, leaving many people homeless. Drones took pictures for the rescue (救援) teams. This helped the teams judge the situation quickly and offer help to the areas that were hardest hit. Drones are also helping environmental organizations. Every year, poachers (偷猎者) kill many endangered animals. To stop them, the WWF uses drones. “They help us see things that we can’t,” says Colby, who works for the WWF. Drones can easily identify (识别) poachers in the dark. As well as finding poachers, these tools can be used to follow and protect animals. Scientists at a university plan to use them for a project: recording wildlife and identifying animal groups. The project leader believes drones will become widely used. “I think we will have plenty of drones flying over forests,” he predicts. A tool made for war is now being used to save lives. “Drones can be good for both humans and animals. There’s nothing that can take the place of a good scientist. But now, thanks to drones, scientists are able to finish projects they’ve never imagined before,” says Kike, a man who cares about the environment. 1．What do drones do for the people in Rwanda? A．They take clear pictures. B．They help the homeless in time. C．They send medicine fast. D．They judge the situation carefully. 2．What does the underlined word “They” in Paragraph 3 refer to? A．The drones. B．The poachers. C．The animals. D．The organizations. 3．What are drones mainly used for in Paragraph 3? A．Starting a project. B．Finding lost people. C．Protecting animals. D．Recording daily life. 4．What can we infer from Kike’s words? A．Wars have brought many problems. B．New technologies need improvement. C．People should protect the environment. D．Drones can help scientists do more things. 5．In which section of a magazine can we read the text? A．Nature. B．Technology. C．Health. D．Travel.
