八下沪教五四制unit2作文专练 the most useful invention in my view 题目一（推荐信） 题目： 学校科技社团正在举办“我最爱的发明”推荐活动，请你给社团负责老师写一封推荐信，推荐你认为最有用的一项发明。信中需要： 1. 介绍这项发明的名称、发明者（如果知道）和它的基本功能； 2. 说明这项发明如何改变了人们的生活（至少两个具体例子，如出行更方便、学习更高效等）； 3. 解释你为什么认为它比其他发明更有用（即你的推荐理由）。 思路精讲 这是一封推荐信，要求学生有理有据地表达自己对某项发明的看法。教师应引导学生选择一个贴近生活、有话可说的发明，如手机、互联网、电灯、轮子、交通工具等。重点在于：先说明发明的基本功能，然后用具体生活场景（如“过去没有它时人们如何，现在有了它之后如何”）展示它的价值。最后通过对比（与其他发明比较）或突出其不可替代性，说明为什么它“最有用”。结构：第一段表明推荐意图并介绍发明的基本信息；第二段用两个生活例子说明它如何改变生活；第三段说明推荐理由（为何它是最有用的）。 写作要点分析 1. 推荐信格式：称呼（Dear Mr./Ms. / Dear teacher）、正文、结尾（Yours sincerely）、署名。 2. 对比论证：使用“Before the invention, people had to... But now, with it, we can...”的对比结构，突出发明的价值。 3. 三个要点：①发明的名称、发明者、基本功能；②两个改变生活的具体例子；③推荐理由（为什么比其他发明更有用）。 重要句型和词组 · I am writing to recommend what I think is the most useful invention — ... · It was invented by... (if known) / It has been around for... years. · Its main function is to... / People use it to... · Before this invention, people had to... which was very... · Now, with this invention, we can...

The first true smartphone was invented by Apple company in 2007. Its main function is to let people communicate wirelessly, but it can do much more than that. Before smartphones, people had to carry a camera, a map, a music player, and a phone separately. If you got lost, you had to ask strangers for directions. If you wanted to take a photo, you needed a heavy camera. Now, with a smartphone, we can do all these things with just one small device. For example, we can video call our parents when we are away. Another example is that we can look up any information instantly — like checking the weather or learning a new word. I believe the smartphone is the most useful invention because it combines so many tools into one. It has changed the way we communicate, learn, and live. Without it, our daily life would be much harder and less convenient. That’s why I strongly recommend the smartphone as the most useful invention. Yours sincerely, Li Hua 题目二（倡议书） 题目： 学校正在举办“科技改变生活”主题周活动，请你以学生会名义写一份倡议书，号召同学们关注并善用最有用的发明——互联网。内容包括： 1. 说明互联网这项发明的基本功能和普及程度（几乎人人都在用）； 2. 列举互联网给学习和生活带来的三个具体好处（如在线学习、与远方亲友联系、获取新闻资讯等）； 3. 提出三项倡议，号召同学们合理使用互联网（如每天用1小时学习英语视频、不沉迷游戏、用网络查资料完成作业等）。 教师思路精讲 这是一份倡议书，旨在引导学生认识互联网的价值并学会合理使用。教师应引导学生先肯定互联网是一项伟大的发明，它已经深入生活的方方面面。然后列举三个具体好处，要贴近学生的学习生活（如上网课、查资料、看纪录片）。最后提出合理使用的倡议，注意平衡“善用”与“防沉迷”，给出可操作的建议。语气要积极、正面，强调互联网是工具，关键在于如何使用。结构：第一段肯定互联网的价值；第二段列举三个好处；第三段提出三项合理使用的倡议。 写作要点分析 1. 倡议书格式：标题（如“Proposal: Use the Internet Wisely”）、称呼（Dear fellow students）、正文、署名和日期。 2. 数据支撑：可用模糊数据增强说服力（如“billions of people”“almost everyone”）。 3. 三个要点：①互联网的基本功能和普及程度；②三个具体好处；③三项合理使用的倡议。注意倡议要正面、可操作。 重要句型和词组 · Dear fellow students, what is the most useful invention in your opinion? I believe the answer is the Internet. · The Internet connects almost every corner of the world. Billions of people use it every day. · It has brought us three great benefits. · First, it allows us to learn online. We can watch lessons from top teachers. · Second, it helps us stay in touch with family and friends far away through video calls. · Third, it gives us instant access to news, books, and interesting facts. · However, every tool can be used well or poorly. Here are three actions we suggest: · First, spend 30 minutes every day watching educational videos in English. · Second, use the Internet to search for information for your homework, not just for fun. · Third, set a timer when you play games — no more than one hour a day. · Let’s make the most useful invention truly useful for our growth. 高分范文 Proposal: Use the Internet Wisely Dear fellow students, What is the most useful invention in your opinion? I believe the answer is the Internet. Since it was created, it has connected almost every corner of the world. Billions of people, including all of us, use it every day for work, study, and fun. The Internet has brought us three great benefits. First, it allows us to learn online. We can watch lessons from top teachers, learn a new language, or even take a virtual tour of a museum. Second, it helps us stay in touch with family and friends who live far away. A video call can make us feel close even when we are thousands of miles apart. Third, it gives us instant access to news, books, and interesting facts. With just a few clicks, we can find answers to almost any question. However, every tool can be used well or poorly. Too much gaming or watching silly videos is a waste of time. Here are three actions we suggest. First, spend 30 minutes every day watching educational videos in English — you will improve your listening skills. Second, use the Internet to search for information for your homework instead of just copying answers. Third, set a timer when you play games — no more than one hour a day. Let’s make the most useful invention truly useful for our growth. Use the Internet wisely and it will be your best friend. Student Council April 27, 2026 学科网（北京）股份有限公司 $
