(1) Ada Lovelace；(2) Alan Turing；(3) a room；(4) faster and smaller；(5) connect to the internet / run different apps。 3. 1940s与1971。前者指出早期计算机有房间那么大，后者说明微处理器推动设备变小、变快。 4. A。可引述的依据：a computer program could do a lot more。 5. Ada’s ideas；the Turing machine。按教材叙述作答。 6. Some experts thought people would not want a computer at home. But the company sold thousands in two years. So a prediction can be wrong / needs to be checked against later evidence. 7. a—H；b—T；c—M。H强调文本记述的过去事件；T强调文本中的未来表述；M强调学生自己提出的可能性。 8. China / Chinese researchers。例：The text describes early computers in England and Germany. It also introduces Zuchongzhi, built by Chinese researchers. These examples show contributions from different places. 可另选英国人物、美国公司等作为证据。 9. 展品说明示例，共51词 The microprocessor According to the textbook, Ted Hoff was the main inventor of the microprocessor in 1971. This small device was a major breakthrough. It helped computers and other electronic devices become faster and smaller. Compared with early computers that filled a room, smaller devices became much easier for people to use later. 10. 开放作答。例：In the future, computers may help us remember what to take to school. I think this because small devices can collect and share information. 保留may等预测标记即可，不评价其一定能否实现。 展品说明评价共6分：教材事实准确2分；解释生活影响2分；联系人物、地区或前后变化1分；语言清楚且达到基本篇幅1分。 教师提示：时间线服务于理解“想法的传承与不同贡献”，不作孤立年份背诵。有关未来量子计算机的表述作为教材展望处理，不扩写为“所有任务上都更快”的结论。教材的简化历史叙述不用于裁定所有“世界第一”。 第 页 学科网（北京）股份有限公司 $
