　　When talking about inventions, you can think of a large number of them in our life. It seems that they keep making a difference to the world. They not only make our life convenient, but also help us be pleased with the changing styles of life. In history, the wheel, the telephone and the light bulb(电灯泡) are mentioned as three of the most important inventions. 　　People have long depended on walking to go from one place to another. Because of the invention of the wheel, people didn't have to remain the only way of transportation — walking. Instead, people can travel in a faster and more interesting way. They used wheels on carriages(马车) and bikes years later. In the early 19th century, the first trains began to carry passengers. It became a hit at that time. At the beginning of the 20th century, cars became popular. Without the wheel, we would not have the above inventions. 　　The telephone, which was invented in 1860, allows people to keep in touch with each other anytime, munication over long distances(距离) is not a problem any longer. Suddenly, people began to try the new way and experience the new lifestyle. 　　Before the invention of the light bulb, people had to use oil lamps, gas lamps or candles to see at night. In 1879, the situation totally changed. An American, Thomas Edison, invented the first practical light bulb. From then on, at night, people can do nearly all the things they can do in the daytime with the help of the light bulb. They don't have to hurry to do what they need to do before it's dark.
