The one that impresses me most is the invention of the Internet. The Internet was first developed by scientists in the 1960s, but it became widely used in the 1990s. It has completely changed the way we communicate, work and learn. Now we can get information in seconds, take online courses, and keep in touch with friends far away. It makes the world smaller and more convenient. From this great idea, I have learned that a single thought can create huge changes. It encourages me to think freely and never be afraid of new ideas. Who knows? Maybe one day my idea will also make a difference. 学科网（北京）股份有限公司 $
