I would like to recommend the high-speed train. It was developed in China, and now it connects almost every big city in our country. With it, journeys that once took a whole day can be made in only a few hours. Our travels have become much easier and faster, and the world has become a much smaller place. What is more, because of it, tourism and economic development in many areas have been increased. In my opinion, it is a wonderful invention. It is used by millions of people every day and has really changed our lives. I hope you will have a chance to experience it one day.

Today I would like to talk about the radio, one of the most useful inventions of all time. Before the radio was invented, information travelled very slowly. Then the world was made much smaller by the radio, because news could be spread around the world in seconds. It was invented by an Italian inventor called Guglielmo Marconi, and in 1901, a radio message was sent across the Atlantic Ocean for the first time. Because of it, some other important inventions were developed as well, such as the television. It also had a big effect on music. In my opinion, creative ideas can really change our lives. Let us come up with more ideas and make the world better. Thank you! 学科网（北京）股份有限公司 $
