The first words spoken were, “Mr Watson — come here — I want to see you.” This invention has changed how people communicate across long distances. I think it is one of the most important inventions in history. Part 2 Adding pictures to a display board is important because they help people understand the information quickly. People can see what old telephones looked like. For example, a picture of Bell’s first telephone makes the board more interesting. I think pictures also make the board more attractive and fun to read. Part 3 Learning about the development of an invention is important because it shows how ideas grow and improve over time. We can see how telephones changed from big boxes to small mobile phones. This helps us understand how today’s technology came to be. I believe knowing the past helps us create a better future. 1 学科网（北京）股份有限公司 $
