Unit5 Section B 3a-3c 读写课公开课课件2026-2027学年人教版英语九年级上册

The invention of the plane has greatly changed the world. However, IT seems that its inventions, orval right and wilder right, were not looking to change the world at all. Rather, they just wanted to fly like birds to solve the problem of heavier than airflow. The right brothers begin working with gliders. There were two main chAllenges. The first was how to get the glider into the air. The second was how to control IT. Once IT was flying for both problems, they found their solution by looking at how birds flu. After they solve these problems, they added an engine to the glider. Then in december nineteen zero three, the world's first plain flights were made. The invention of the plane has made our travels around the world much easier and faster. Journeys that once took days, weeks or even months can now be made in only a few hours. As a result, communication among people in different countries is now much easier, and the world has become a much smaller place. Our schools science festival is coming. The english corner will make an inventions around us wall. We will become Young invention writers. First we will read an invention story and learn how to introduce an invention. Then we will choose an invention from our daily lives . and write an english introduction for the wall. Presentation Unit5 Power of Ideas Section B How do we turn ideas into reality?

Look and write While-writing The invention of the light bulb has greatly changed people’s lives. Its inventor is Thomas Edison. At first, he just wanted to create a clean and long-lasting light to replace oil lamps. To solve the problem of poor lighting at night, Thomas Edison began doing lots of experiments. He faced two main challenges. The first was finding suitable material for the filament. The second was stopping the filament from burning out quickly. For both problems, he found solutions by testing thousands of different materials. After hundreds of failures, in 1879, the practical light bulb was invented. The light bulb has made our daily life much more convenient. People no longer need to depend on dangerous oil lamps. As a result, people can work, study and take part in activities freely after dark, and human society has developed faster.

Read and learn Post-writing Presentation Look and write Post-writing 在英语课上，你们班开展了一次以“The Power of Ideas”为主题的讨论。请你根据以下要点，用英语写一篇短文，向校英语报投稿，分享你对“想法的力量”的理解。 要点提示： 1. 想法的重要性：想法可以改变世界（举例说明）； 2. 如何产生好的想法：观察生活、多问问题、合作交流等； 3. 作为中学生，我们该如何培养创造性思维？ Presentation Look and learn Post-writing As the saying goes, “A good idea can change the world.” I strongly believe that ideas have great power. Here are my thoughts on this topic. Ideas are powerful enough to change the world. Many great inventions, such as the Internet, came from simple creative thoughts. Good ideas won’t appear easily. We need to observe daily life, keep curious and ask more questions. Besides, valuable ideas can be improved through collaboration with partners. As middle school students, we should develop creative thinking. We’d better keep curious and dare to put forward new opinions. Don’t fear failures, for they can guide us to turn ideas into reality. In short, never stop thinking and creating. Presentation Watch and say Post-writing Presentation Look and say Post-writing Great inventions come from people’s wishes and hard work. If we keep trying, we can also create something useful. Presentation Look and summarize Post-writing Let’s summarize what we have learned. We have learned: the invention story of the plane; the structure of an invention introduction; useful expressions for problems, actions and effects. We can: read an invention story with PIE; organize writing with PIE; introduce an invention from our daily life.

Both brothers were pioneers credited with inventing the first airplane. In late nineteen, no one, the right brothers had gathered the area dynamic data they needed to build a successful flying machine. And in one thousand nine hundred two, the Wright brothers had built their latest glider. Based on this data, they had identified a wing shape that was efficient, producing the expected lift and engineer controls that were responsive. The glider would also use a trAiling rudder for ya, therefore enabling the right brothers to navigate in the air in all three dimensions. Following the success, the next stage for the brothers was powered flight. No manufacturers could provide an light enough and powerful enough for their needs, so the brothers had to design and build their own. The fire was designed in a byplay e configuration with a wooden air frame and a wings'. And of twelve point three meters or forty feet four inches, the pilot flew on his stomach on the lower wing, steering by moving a cradle attached to his hips. This cradle pulled wires, which worked the wings and turn the rudder. The right fire one, based on the previous glider, was set up near Kitty hawk, north CarOlina, in the united states of amErica on december seventeen, nineteen o three, where there was a hill and a good breeze. The first flight lasted twelve seconds. Traveling thirty six metres are one hundred and twenty feet with orvil piloting. Three more flights were made on that day, with wilber achieving the best flight covering two hundred and fifty five point six meters or eight hundred and fifty two c and fifty nine seconds. The Wright brothers had made history with the first successful flight of a controllable self propelled heaven ier than air machine. Over the next few years, the right brothers developed new fliers while remaining secretive in an attempt to secure patterns and contracts, subscribe for more history videos.
