五、写作清单
写一项新发明的文章
1. 话题分析
本单元话题围绕 “新发明” 展开,核心是阐述自己设想的新发明,需讲清发明是什么(What it is)、外观怎样、有哪些主要功能以及能带来什么好处,体现新发明的创意与价值,让读者清晰了解发明的全貌。
2. 写作内容
写一段文字阐述对“新发明创意”的文章,详细说明新发明的关键内容(是什么、外观、功能、好处等),用清晰的逻辑和具体的描述让读者理解发明的独特之处。
3. 写作要点
1. What it is:明确新发明的具体名称与基本定义,比如范文里直接点明“My invention is a flying car.”,清晰告知读者发明是什么。
2. What it looks like:描述发明的外观特征,像“The flying car has four wheels and two wings.”,让发明有直观的形象呈现。
3. Main features & What it can do:阐述发明具备的主要特点和能实现的功能,例如飞行汽车“can run on land and fly in the air” “has a top speed of 300 km/h” “can be controlled by voice”等,体现发明的性能。
4. Benefits of the invention:说明发明能给人们生活带来的好处,如 “help people avoid traffic jams” “make driving a more exciting experience”等,突出发明的价值。
5. Key example support: 用具体例子让论点更有说服力。
4. 写作思路提示
1. 想象面向关心科技创新、对新发明感兴趣的群体(如杂志《Teen Life Magazine》读者),需用贴近生活、具体可感的例子(像日常出行遇到交通拥堵,新发明如何解决这类问题 ),让新发明的创意和价值更真实可触,引发读者共鸣 。
2. 梳理思路:先确定新发明的核心定位(是什么),接着依次描述外观、功能、好处,为每个部分找具体例子支撑(如讲功能时,举例在什么场景下怎么运作 ),再用连贯的语言把这些内容组织起来,让文章逻辑清晰。
5. 写作步骤详解
1. 构思: 选择一个新颖且有实际意义的新发明方向,确定要重点展现的1 - 2个核心亮点(比如独特功能、解决的关键问题),像范文里飞行汽车既解决交通拥堵,又带来新奇体验这两个亮点 。
2. 写作: 开头直接点明新发明是什么(如 “My invention is a flying car.” ),然后按 “观点(外观 / 功能等 ) + 例子 / 细节描述” 展开,每段聚焦一个方面(一段讲外观,一段讲功能,一段讲好处等 ),让内容有条理。
3. 结尾: 简单总结新发明的价值,呼应主题,比如强调它能给生活带来的改变、对未来的意义等,让文章收尾完整。
6. 词汇运用提示
1. 使用“invention, look like. have. wheel, wing”来描述发明品的基本信息和外观。
2. 使用“can, speed, control, turn into, use”等来描述功能、特点。
3. 用“benefit, avoid, traffic jams, exciting, experience”来描述好处、价值。
7. 句型运用提示
1. 使用______________陈述。
2. 运用______________让逻辑紧密。
8. 范例作文
A flying car
My invention is a flying car. It is fast, convenient and green.
The flying car has four wheels and two wings. It can run on land and fly in the air.
It has a top speed of 300 km/h. You can travel farther distances in less time. The car can be controlled by voice. If you shout “Fly!”, the car will turn into a plane in 30 seconds. Then you can fly in the air. You will be as free as a bird. Instead of petrol, the car uses solar power, so it will not pollute the air.
As there are more cars on the road, there are more traffic jams. My invention will help people avoid traffic jams. It will make driving a more exciting experience too. People can fly anywhere they like and enjoy the view at the same time.
译文:
我的发明是一款会飞的汽车。它速度快、便捷又环保。
这款飞行汽车有四个轮子和两对机翼,既能在陆地上行驶,也能在空中飞行。
它的最高时速可达 300 千米。借助它,你能在更短时间内抵达更远的地方。汽车可以通过语音控制,要是你大喊一声 “飞!”,它会在 30 秒内变形为飞机,随后你就能在空中翱翔,像鸟儿一样自由。而且,它不用汽油,依靠太阳能驱动,不会污染空气。
如今道路上的汽车越来越多,交通拥堵也愈发严重,我的这项发明能帮人们避开交通堵塞,还能让驾驶变成更刺激的体验。人们可以开着它飞到任何想去的地方,同时欣赏沿途的风景。
9. 实战演练
请你根据下面蛛网图中的提示,以“My invention”为题写一篇80词左右的短文。可以适当发挥。

五、写作清单
写一项新发明的文章
1. 话题分析
本单元话题围绕 “新发明” 展开,核心是阐述自己设想的新发明,需讲清发明是什么(What it is)、外观怎样、有哪些主要功能以及能带来什么好处,体现新发明的创意与价值,让读者清晰了解发明的全貌。
2. 写作内容
写一段文字阐述对“新发明创意”的文章,详细说明新发明的关键内容(是什么、外观、功能、好处等),用清晰的逻辑和具体的描述让读者理解发明的独特之处。
3. 写作要点
1. What it is:明确新发明的具体名称与基本定义,比如范文里直接点明“My invention is a flying car.”,清晰告知读者发明是什么。
2. What it looks like:描述发明的外观特征,像“The flying car has four wheels and two wings.”,让发明有直观的形象呈现。
3. Main features & What it can do:阐述发明具备的主要特点和能实现的功能,例如飞行汽车“can run on land and fly in the air” “has a top speed of 300 km/h” “can be controlled by voice”等,体现发明的性能。
4. Benefits of the invention:说明发明能给人们生活带来的好处,如 “help people avoid traffic jams” “make driving a more exciting experience”等,突出发明的价值。
5. Key example support: 用具体例子让论点更有说服力。
4. 写作思路提示
1. 想象面向关心科技创新、对新发明感兴趣的群体(如杂志《Teen Life Magazine》读者),需用贴近生活、具体可感的例子(像日常出行遇到交通拥堵,新发明如何解决这类问题 ),让新发明的创意和价值更真实可触,引发读者共鸣 。
2. 梳理思路:先确定新发明的核心定位(是什么),接着依次描述外观、功能、好处,为每个部分找具体例子支撑(如讲功能时,举例在什么场景下怎么运作 ),再用连贯的语言把这些内容组织起来,让文章逻辑清晰。
5. 写作步骤详解
1. 构思: 选择一个新颖且有实际意义的新发明方向,确定要重点展现的1 - 2个核心亮点(比如独特功能、解决的关键问题),像范文里飞行汽车既解决交通拥堵,又带来新奇体验这两个亮点 。
2. 写作: 开头直接点明新发明是什么(如 “My invention is a flying car.” ),然后按 “观点(外观 / 功能等 ) + 例子 / 细节描述” 展开,每段聚焦一个方面(一段讲外观,一段讲功能,一段讲好处等 ),让内容有条理。
3. 结尾: 简单总结新发明的价值,呼应主题,比如强调它能给生活带来的改变、对未来的意义等,让文章收尾完整。
6. 词汇运用提示
1. 使用“invention, look like. have. wheel, wing”来描述发明品的基本信息和外观。
2. 使用“can, speed, control, turn into, use”等来描述功能、特点。
3. 用“benefit, avoid, traffic jams, exciting, experience”来描述好处、价值。
7. 句型运用提示
1. 使用一般现在时陈述。
2. 运用连接词让逻辑紧密。
8. 范例作文
A flying car
My invention is a flying car. It is fast, convenient and green.
The flying car has four wheels and two wings. It can run on land and fly in the air.
It has a top speed of 300 km/h. You can travel farther distances in less time. The car can be controlled by voice. If you shout “Fly!”, the car will turn into a plane in 30 seconds. Then you can fly in the air. You will be as free as a bird. Instead of petrol, the car uses solar power, so it will not pollute the air.
As there are more cars on the road, there are more traffic jams. My invention will help people avoid traffic jams. It will make driving a more exciting experience too. People can fly anywhere they like and enjoy the view at the same time.
译文:
我的发明是一款会飞的汽车。它速度快、便捷又环保。
这款飞行汽车有四个轮子和两对机翼,既能在陆地上行驶,也能在空中飞行。
它的最高时速可达 300 千米。借助它,你能在更短时间内抵达更远的地方。汽车可以通过语音控制,要是你大喊一声 “飞!”,它会在 30 秒内变形为飞机,随后你就能在空中翱翔,像鸟儿一样自由。而且,它不用汽油,依靠太阳能驱动,不会污染空气。
如今道路上的汽车越来越多,交通拥堵也愈发严重,我的这项发明能帮人们避开交通堵塞,还能让驾驶变成更刺激的体验。人们可以开着它飞到任何想去的地方,同时欣赏沿途的风景。
9. 实战演练

【例文】 My invention
My invention is a flying camera.
It has an eye but no wings. It looks like a set-top box. Its top speed can be 30km/h, which is fast enough for a small flying camera like this. It can fly and take photos in the air. I can use it to take photos of houses and trees from above. It’s easy to control it. I can use my voice to control it. It is also green because it uses solar power, so there is no pollution.
I love my invention.
