AI can help computers learn and do some jobs. Scientists say AI can forecast (预报) the weather even faster and better than old ways. The old way to forecast the weather is collecting data (数据) about the air. The data may come from weather planes. Then people send the data to supercomputers to make weather reports. Although supercomputers are strong， they need many hours to get the results. Scientists create AI models (模型) to forecast future weather quickly. They use two groups of data： the weather now and the weather six hours ago. AI models are very useful because it only takes a few minutes to get the results. Will AI take over old models？ Scientists say it probably won’t. That’s because AI needs old models to collect data and then learn from the data. People will use AI together with old models. Old ways can’t finish difficult jobs， such as telling when and how much it will rain soon. So people hope AI can finish difficult jobs and it can give people enough time to solve problems from bad weather. 1. Does AI forecast the weather faster or slower than old ways？ 　 2. Where may the data in old ways come from？ 　 3. How long does it take AI models to get the weather results？ 　 4. Why do scientists think AI will not take over old models？ 　 5. What kind of jobs can’t the old ways finish？ 　 参考答案 课堂跟练 一、 根据提示用单词的恰当形式填空 1.education；2.video；3.technology；4.partners；5.traffic 二、 完成句子， 词数不限 1.traffic accidents 2.lived to be 三、单项选择 A；B；B 四、 根据思维导图复述2a课文 (教材P63) Helen and Jennifer are talking about future predictions. 　In cities， there will be more people.
