Can you describe the situation and your reaction? 你收到过应急预警吗？能描述当时的情形和你的反应吗？ 【提示框】 聊预警经历用「何时+何事+反应」三句式：I got an alert about... It said... I...——为听力里的预警故事热身。 （二）背景拓展 · 中国预警网 DID YOU KNOW? 读背景知识：China is one of many countries with disaster warning systems. The government can warn people with text messages, TV programmes and online notices. In communities, loud alarms go off. Warning times for storms in China have been increased to 42 minutes, with more than 90% being correct. 中国是拥有灾害预警系统的国家之一：政府用短信、电视节目和网上通知预警，社区警报齐鸣；风暴预警时间已提高到 42 分钟，准确率超 90%。 【知识点】 ▶预警三渠道+两数据：text messages／TV programmes／online notices 三渠道；42 分钟预警时间、90% 以上准确率——数字最有说服力，也铺垫听力二的「预警救了多少人」。 【提示框】 记住两个数字 42 和 90%：聊预警话题时抛出准确率数据，观点立刻有分量——「中国智造」的底气就在细节里。 （三）听力一 · Tilly 如何救生 Listen to the radio and choose how Tilly Smith saved lives. 听广播选 Tilly Smith 如何救人：a She ran to the hotel and stayed under the table. b She sensed the danger and warned others. c She helped a 10-year-old girl at school. d She helped her classmates leave the coast.（按 Tilly Smith 真实事迹推断选 b：她察觉危险并警告他人，以实际音频为准。） 发音跟读：/br/——bravely；/fr/——friend。 【知识点】 ▶英雄的关键动作：sense the danger（察觉危险）+warn others（警告他人）——b 是「观察+行动」的组合，a/c/d 都只是被动或局部。 【提示框】 四选项先划动词：ran and stayed／sensed and warned／helped a girl／helped classmates——「警告他人」才是让更多人得救的关键动作。 听力一选答案页 （四）听力二 · 笔记改错 Listen again and correct the mistakes in the host's notes. Cross out the mistakes and write the correct words. 改正主持人笔记六处：①A natural disaster happened in Italy. → Italy 划掉改 Thailand（泰国，2004 年印度洋海啸）。②No one died thanks to a 12-year-old girl, Tily Smith. → 12-year-old 改 10-year-old，Tily 改 Tilly（事发时 Tilly 仅 10 岁）。③Tilly saw the water going away from the beach.（正确，无需改——海水异常退去正是海啸前兆） ④She learnt about tsunamis at school two months earlier. → two months 改 two weeks（按常见记述推断）。⑤She warned people on the beach and they all ran to a school. → a school 改 a hotel（人们跑向高处酒店避难）。⑥That school lesson saved about 1,000 lives. → 1,000 改 100（那堂地理课救了约 100 人）。（以上按语境与史实推断，以实际音频为准。） 【知识点】 ▶改错三步：听前读笔记划可疑点（地名/年龄/数字）→听时逐条验证→划掉错处写正确词——第①条抓地名、第②条抓年龄与拼写、第⑤⑥条抓地点与数字。 【提示框】 数字与地名最易出错：Italy/Thailand、12/10、1,000/100——听到与笔记不一致的瞬间立刻做记号，别等听完整段再回忆。 （五）听力三 · SAFETY NET 预警 App 【过渡语】预警靠英雄更靠工具——一款叫 SAFETY NET 的 App 来了。 Listen to the conversation and fill in the chart about the app. 听对话补全 App 功能表：【Area 地图】show a 1____________（map）; allows you to 2____________（choose）your area. 展示地图，可选定你的区域。【Warning 预警】warns you of upcoming disasters; tells you how 3____________（serious）it might be. 预警将至灾害，告知严重程度。 【Advice 建议】tells you how to stay safe: 4____________（where）to go; ways to 5____________（keep away）from danger. 告知避险去处与远离危险的方法。【Other information 其他】warns you of many natural disasters, eg 6____________（storms）、7____________（fires）, tsunamis, earthquakes; gives you short warning time for earthquakes.（以上按语境推断，以实际音频为准。） 【知识点】 ▶App 四大板块：Area（地图选区）→Warning（预警+严重度）→Advice（去哪+避险法）→Other information（覆盖灾种+地震短预警）——按板块定位填空，七空各归其位。 听力三 App 功能表页 （六）说产品 · 介绍三步法 Listen again. Then talk about how the app is introduced. 再听录音，谈谈这款 App 是如何被介绍的。 Learning to learn（Introducing a product）：To introduce a product, state its name and main function, eg giving disaster warnings. Say how it operates, using an example if possible. Finally, give other details, such as its cost, look and drawbacks. 介绍产品三步：名称与主要功能→运作方式（尽可能举例）→其他细节（价格、外观、缺点）。 【知识点】 ▶介绍三步曲：name+main function（叫什么、干什么）→how it works（怎么用，举例子）→other details（价格/外观/缺点）——SAFETY NET 的介绍正是按这三步走的。 【提示框】 提缺点不是拆台：One drawback is that... 让介绍更可信——能说出不足的人，观众才信他的优点。 （七）小组任务 · 救生科技发布 【过渡语】除了预警 App，无人机也在救人性命——选一件科技开个发布会。 Work in groups. Choose a piece of life-saving technology and introduce it. Do more research if necessary. 选一件救生科技介绍——Drones 无人机：take photos and videos to show the effects of disasters（拍照片视频展示灾害影响）／provide useful information to emergency services（为应急服务提供信息）／find survivors and quickly send medicine and food（寻找幸存者、快速送达药品食物）。 问答支架：What's this? — It's... It's made of...／How does it help in disasters? — It can... 表达支架：One new product is called...／The purpose of... is to...／It works by...／As an example, imagine that...／It saves lives by...／One drawback is that... 【知识点】 ▶发布按三步曲走：One new product is called...（名称+功能）→It works by...
