He recorded the bright shop window and the bread coming out of the oven. Then he added fast music, colourful titles and several special effects. He was certain that his two-minute film was ready. ② Before handing it in, Leo showed it to Aunt Lin, the baker. She watched quietly. “The pictures are beautiful,” she said, “but the film feels flat. Where are the people?” Leo looked at the screen again. He had shown almost every kind of bread, but hardly any of the work behind it. ③ He returned the next morning. His camera battery was nearly empty, so this time he had to choose carefully. Instead of filming the shop window again, he recorded Aunt Lin teaching a young worker to fold a piece of dough. The first try went wrong. She laughed, showed him again and waited while he tried once more. Leo kept the sound of their voices. ④ Back at home, he removed most of the music and effects. He put the short lesson at the centre of the film. When he played the new version at school, his classmates asked about Aunt Lin and the young worker. Nobody asked which editing app he had used. Leo smiled and closed the long list of effects on his screen. 注：dough 面团。 21. Why did Leo return to the bakery? A. To film a brighter shop window. B. To record the people doing their work. C. To buy bread for the film club. D. To ask Aunt Lin for a better camera. 22. What does “flat” in paragraph ② most nearly mean? A. Lacking feeling and interest. B. Having a very low sound level. C. Showing objects from above. D. Being shorter than expected. 23. What can we infer about Leo after he edited the film again? A. Quiet films were always best in his view. B. He thought he no longer needed digital tools. C. He preferred filming without a plan. D. Meaningful details mattered more than effects. 24. Which clip would Leo most probably choose for a film about a school garden? A. A bright title moving across the screen. B. A fast list of every tool in the shed. C. A gardener explaining how she saved a plant. D. A list of prices for the newest cameras. 25. Which is the best title for the story? A. The Camera That Ran Out of Power B. More Than Bright Pictures C. A Bakery Without Customers D. The Fastest Way to Edit a Film 答案：21—25 ____________________ （B） ① In 1991, researchers at the University of Cambridge shared a coffee machine. Some worked several floors away. They would walk to the coffee room, only to discover that the pot was empty. Two researchers, Quentin Stafford-Fraser and Paul Jardetzky, decided to solve this small but annoying problem. ② They pointed a camera at the pot and used computer programs to send pictures to screens inside the laboratory. The pictures were small, black and white, and updated about three times a minute. Their quality was poor, but they answered the important question: Was there any coffee? People could check before leaving their desks. ③ In 1993, other members of the team connected the system to the World Wide Web. Now people outside the laboratory could see the pot too. At a time when many web pages showed only still information, the changing picture offered a little window into a real place. People around the world became interested in a coffee pot they would never use. ④ The camera was switched off in 2001 when the laboratory moved. It had begun as a way to avoid wasted walks, rather than a plan for a world-famous invention. Its story is a reminder that new uses for technology can grow from ordinary needs. The problem did not have to be large for the idea to travel far. 注：webcam 网络摄像头；laboratory 实验室。 26. What problem did the researchers first want to solve? A. The coffee machine used too much power. B. Visitors could not find the laboratory. C. Some walks to the coffee room were wasted. D. Their computers could not show any pictures. 27. Why were the simple pictures useful to the researchers? A. They showed how to make better coffee. B. They helped sell a new kind of camera. C. They made the coffee room look larger. D. They answered the question that mattered. 28. What does the “little window” in paragraph ③ refer to? A. A way to watch a real place from far away. B. A new window built in the coffee room. C. A small hole in a computer screen. D. A page giving directions to Cambridge. 29. How is the passage mainly organised? A. A prediction → Two opinions → A debate B. A problem → A solution → Wider use → A lesson C. A rule → Three examples → A warning D. A result → A comparison → A shopping guide 30. What is the writer’s main purpose? A. To teach readers how to build a camera. B. To persuade researchers to drink less coffee. C. To link an everyday need to a digital invention. D. To compare the quality of modern webcams. 答案：26—30 ____________________ （C） BORROW A DEVICE AT RIVER LIBRARY Need a device for a school task?

If an account gives no writer’s name or source, do not depend on it alone.   37   It may explain where the picture was taken and what actually happened. Even a reliable account can repost an old picture.   38   A photo from five years ago may look as if it was taken this morning when its date is missing. Next, compare the message with a school notice or another reliable report. If there is no news of a closure on the school’s own channel, do not tell your classmates to stay at home.   39   Finally, if you are still unsure, ask a teacher before passing the message on. You do not have to be the first person to share a story.   40   A. Try to find the original report. B. Different reliable sources can help you check one story. C. An exciting picture is not enough evidence. D. Waiting for clear information is better than spreading a wrong message. E. The date matters as well. 答案：36—40 ____________________ 三、项目情境 读写综合（共两节，满分20分） 学校准备改进自习室照明。请阅读项目材料，完成下一页的任务。 THE SMART LIGHTING TRIAL The Green Class team tested two systems to reduce wasted lighting without making study rooms uncomfortable.
