A Young Inventor Who:Exekiel Wheeler,13,US What:A machine to help people speak to astronauts at the International Space Station (ISS). How:At the age of 8,he came up with the idea to connect with the ISS by using ham radio (业余无线电).Wheeler wasn't only interested in talking to the astronauts himself.He wanted to let his friends talk to them too,asking about everything they wanted to know.To complete his invention,he needed a ham radio and a tracker(追踪器).He made his own tracker with a3-meter-long antenna(天线).But later he found the tracker didn't work well.So,he 3D- printed two other important parts.Then he used a small computer and an LCD screen to connect with the ISS.

(不超过15词) 10.How old was Wheeler when he came up with the idea? (不超过5词) 11.What did Wheeler need to complete his invention? (不超过10词) 单元作 【话题分析】 “发明”是初中英语写作中常见的主题。这 一话题不仅要求学生描述一项发明是什么，更强 调“如何发明”的过程。写这类作文时，核心在于 展现从“问题”到“解决方案”的完整链条。 【素材积累】 ●开头句 There are many great inventions in the world, but my favourite one is the telephone. Have you ever wondered how something as common as the light bulb was invented? Inventions often come from people who are curious and never give up. The story of how the airplane was invented is both interesting and inspiring. One of the most useful inventions in history is the computer. Many inventions happen by accident,and the microwave oven is a good example. The invention I want to talk about is the smartphone,which has changed our lives a lot. When we think of great inventors,Thomas Edison often comes to mind. Every invention starts with a problem that needs to be solved. The invention of the wheel was a huge step for human history. I believe the best inventions are those that make life easier for people. ●中间句 The inventor kept trying different materials until he found the right one. They carried out hundreds of experiments before they succeeded. At first,people laughed at the idea,but the inventor did not give up. 文指导 The inventor spent many nights working hard to improve the design. As a result,a simple mistake led to a world- changing invention. He wrote down his ideas in a notebook and tested them one by one. People were amazed when they saw the invention for the first time. It took over ten years to turn the idea into a real product. The inventor learned from every failure and used those lessons to move forward. ●结尾句 Thanks to this invention,our lives have become much more convenient. This story shows that hard work and patience can lead to great things. Even today,we still use this invention in our daily lives. The inventor's success reminds us that failure is just part of the journey. Without this invention,the world would be very different. It is a great example of how a simple idea can grow into something important. I think everyone can learn something from the inventor's spirit. This invention has truly stood the test of time. Who knows?Maybe one day you will invent something great too. ●名言积累 To invent,you need a good imagination and a pile of junk.要发明创造，你需要丰富的想象力 和一堆“垃圾”。 Necessity is the mother of invention,需要是发 明之母。Section B How can we improve 27.It lasts for only about 15-30 our memory? seconds. 第四课时1a一1e 28.It mainly talks about how to 1.passage(s)2.discuss 3.view improve ways/find good ways 4.effective 5.engine 6.address to remember words. 7.To start with Unit 5 Power of Ideas 8.wears them out Section A What changes can 9.bank account inventions bring to our lives? 10.likely to rain 第一课时1a一2d 11-13 DAC 14-18 DBCAB 1.invention 2.itself 3.printer 19-23 CDABD 4.produces 5.camera 第五课时2a一3c 6.sunglasses 7.plastic 1.blood 2.notebooks 3.nuts 8.Hundreds of 9-13 BFCAE 4.fully 5.increase 6.wound 第二课时3a一3d 7.mall 8.recognize 9.divide 1.invented 2.distance 10-14 CAEBD 3.developed 4.was sent 单元作文指导 5.has effect on Dear Mr Worried, 6.of all time I'm sorry to know that you7.in seconds have some problems recently. 8-12 CFEBD Students meet many problems and 第三课时Grammar Focus4a一4c feel stressed in their studies.Your 1.wasn't finished 2.was given question is also very common,so 3.was seen 4.was invited you don't need to worry too much. 5.is used 6.was sold Here is my advice. 7.was stolen 8.is locked First,although you study 9.were taught hard,maybe you lack effective 10.was looked after learning methods.You can ask 11.economic 12.wheel teachers or classmates for advice on how to learn better.Second,for 13.Tourism 14.is gained 15.all over the world memory problems,you can try some memory techniques like 16.is supposed to finish making mind maps or repeating 17.is started 18.are drunk regularly.Third,about stress,you 19.was invented 20.called can do some sports or listen to 21.was made 22.gave music to relax, 23.were sold 24.was bought I hope these suggestions can 25.named 26.opened 27.made help you.I believe everything will Section B How do we turn get better soon. ideas into reality?
