Many great inventions in history were born to solve problems in daily life. Just like the Flowbee, which was invented because Rick Hunt wanted to cut hair with less mess. Life needs push people to think creatively and turn ideas into reality. Such inventions are not only practical but also make life easier. Without real needs, many inventions would be meaningless. We should observe life carefully and pay attention to the problems around us. With a creative mind, we can use innovation to improve our life. 【拓展2译文】 需求是创新之母。历史上许多伟大的发明都是为了解决日常生活中的问题而诞生的。 就像Flowbee真空理发器，它的发明源于里克·亨特想要更整洁地理发的需求。生活需求激发人们的创新思维，推动想法转化为现实。这样的发明不仅实用，还能让生活更便捷。没有真实需求，许多发明都会失去意义。 我们应该仔细观察生活，关注身边的问题。拥有创新思维，我们就能用创意改善生活。 本话题作文的一些实用短语与句型积累 一、核心主题词汇 1.发明与机器相关（单元重点） · 机器与功能：robot vacuum cleaner 扫地机器人；shared bikes 共享单车；power button 电源键；smart lock 智能锁；move back and forth 来回移动；operate 操作；clean automatically 自动清洁；solve problems 解决问题 · 被动语态相关：be invented 被发明；be designed 被设计；be controlled 被控制；be equipped with 配备有；be used 被使用；be widely spread 被广泛普及；be painted 被漆成 · 创新与感悟：invention 发明；creativity 创造力；innovation 创新；practical 实用的；convenient 便捷的；environmentally friendly 环保的；daily life 日常生活；great convenience 极大便利 · 动作与表达：press the button 按按钮；unlock with phone 用手机解锁；turn ideas into reality 把想法转化为现实；observe life 观察生活；pay attention to 关注 1. 语法相关（单元重点） · 一般过去时被动语态（主语+was/were+过去分词）： · The machine was invented in 2010.（这款机器于2010年被发明。） · These bikes were designed by young engineers.（这些自行车由年轻工程师设计。） · The lock is controlled by a phone app.（这个锁由手机应用控制。） · Many shared bikes are used in big cities.（许多共享单车在大城市投入使用。） · 被动语态的特殊疑问句： · Who was the Flowbee invented by?（Flowbee是由谁发明的？） · When was the robot vacuum cleaner first used?（扫地机器人最初是何时投入使用的？） 1. 表达类（单元基础） · 逻辑连接：just like 就像；what’s more 更重要的是；so 所以；because 因为；not only...but also... 不仅……而且……；without 没有 · 感悟表达：bring great convenience 带来极大便利；solve the “last mile” problem 解决“最后一公里”问题；combine technology and life 结合科技与生活；turn ideas into reality 把想法转化为现实；improve our life 改善我们的生活 二、实用句型积累 1.介绍特色机器（贴合单元核心） · My favorite special machine is...just like the one mentioned in the textbook—it... 我最喜欢的特色机器是……就像课本中提到的那款一样——它……，例：My favorite special machine is the soybean milk maker just like the one mentioned in the textbook—it can make fresh soybean milk easily. · It looks...and was invented to... 它看起来……，其发明是为了……，例：It looks simple and was invented to help people make healthy drinks at home. · You just...and it will... 你只需……，它就会……，例：You just put soybeans and water in it, and it will make delicious soybean milk in 20 minutes. 1. 分享发明相关感悟（贴合单元主题） · ...were designed to... ……的设计是为了……，例：These smart water bottles were designed to remind people to drink water regularly. · They were first used in...and soon... 它们最初在……投入使用，很快就……，例：They were first used in hospitals and soon became popular among office workers. · I think they are a great invention that... 我认为它们是一项伟大的发明，……，例：I think they are a great invention that makes health management easier. 1. 论述创新的重要性（贴合单元内涵） · Need is the mother of innovation. 需求是创新之母，例：Need is the mother of innovation.
