It's not rest worry to be. Section B How can we turn ideas into reality? Writing (3a-3c) 1.To understand the text about the plane and find out how the Wright brothers invented it; 2.To identify the structure of an introduction to an invention (basic information, development process, and its influence); 3.To be able to write your own introduction to an invention using the given information and key expressions. Over 100 years ago, two brothers also had this dream. They didn’t just dream it — they turned it into something that changed the world forever. Can you guess who they are, and what they invented? Imagine you could fly like a bird. What would you do first? Where would you go? The Wright Brothers and planes Now let’s read a text to learn more about them. 3a The invention of the plane has greatly changed the world. However, it seems that its inventors, Orville Wright and Wilbur Wright, were not looking to change the world at all. Rather, they just wanted to fly like birds. To solve the problem of heavier-than-air flight, the Wright brothers began 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 solutions by looking at how birds flew. After they solved these problems, they added an engine to the glider. Then, in December 1903, the world’s first plane 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. P49 Read the text and analyse the structure.
