话题词汇/短语识记 人工智能:artificial intelligence (AI) 机器学习:machine learning 深度学习:deep learning 神经网络:neural networks 算法:algorithm 数据挖掘:data mining 自然语言处理:natural language processing (NLP) 计算机视觉:computer vision 自动驾驶:autonomous driving 智能助手:virtual assistant 人机交互:human-computer interaction 语音识别:speech recognition 图像识别:image recognition 伦理问题:ethical issues 数据隐私:data privacy 自动化:automation 智能家居:smart home 机器人技术:robotics 强化学习:reinforcement learning 人工智能伦理:AI ethics 知识点1:时间状语从句 定义:时间状语从句用于描述动作发生的时间,由when, while, as, before, after, until, since等引导。 when:表示某个时间点。 例:When AI becomes mainstream, many jobs will be automated. while:表示两个动作同时发生。 例:While the algorithm is running, the system collects data. until:表示动作持续到某个时间点。 例:The program will not stop until it completes the task. 常见错误: 混淆when与while的用法(如误用“while”表示时间点)。 填空练习(学生自主完成): 1. ___ (When/While) the AI system was updated, it became more efficient. 2. The robot will continue to learn ___ (until/since) it achieves human-like intelligence. 3. ___ (Before/After) the algorithm was improved, the accuracy increased significantly. 知识点2:条件状语从句 定义:条件状语从句用于描述假设情况,由if, unless, as long as等引导。 if:表示假设条件。 例:If AI is used responsibly, it can benefit society. unless:表示否定条件(= if not)。 例:AI will not replace humans unless it surpasses human intelligence. as long as:表示条件满足。 例:AI will thrive as long as there is sufficient data 常见错误: 误用“unless”代替“if”(如:Unless it rains, we will go → If it doesn’t rain, we will go) 填空练习: 4. ___ (If/Unless) we regulate AI, ethical issues may arise. 5. The system will fail ___ (unless/as long as) it receives proper maintenance. 6. ___ (If/As long as) AI is developed ethically, it can improve lives. 知识点3:should型虚拟语气 定义:should型虚拟语气用于表达建议、要求或假设,常见于科技伦理讨论或未来预测 建议类动词后的虚拟语气:suggest, recommend, insist后接“(should) + 动词原形”。 例:Experts suggest that AI be regulated (regulate) to ensure safety. 条件句中的虚拟语气:表示与现在或未来事实相反的假设。 例:If AI should replace (replace) humans, society would face challenges. 常见错误: 忽略should的省略(如误用“be”代替“should be”) 填空练习: 7. The committee recommended that stricter laws ___ (implement) for AI. 8. If AI ___ (should develop) emotions, it ___ (change) human relationships. 9. It is essential that data privacy ___ (protect) in AI applications. 知识点4:非谓语动词作状语 定义:非谓语动词(分词、不定式)可在句中作状语,表示时间、原因、条件等逻辑关系。 分词作状语: 例:Using (use) advanced algorithms, the AI system improved its accuracy. 不定式作状语: 例:To enhance (enhance) performance, engineers updated the software. 常见错误: 混淆分词与不定式的功能(如误用“to use”代替“using”)。 填空练习:
10. ___ (Train) on large datasets, the AI model achieved high accuracy. 11. ___ (To reduce) errors, the team implemented a new algorithm. 12. ___ (Analyze) the data carefully, the system identified patterns. 【对比性练习】 1. 时间状语从句 vs. 条件状语从句: When the AI system is updated, it _______ (become) more efficient. (时间) If the AI system is updated, it _______ (become)more efficient. (条件) 2. 虚拟语气 vs. 真实条件句: If AI should replace humans, society _______ (face)challenges. (虚拟) If AI replaces humans, society _______(face)challenges. (真实). 【课堂内容回顾】请梳理本节课的疑难知识点,以便巩固训练课时进行训练与巩固 请同学们课前识记相关短语 15分钟:检查话题词汇/短语 15分钟:对照学案自学本节课内容 15分钟:教师点拨
