There have been many great inventions, things that changed the way we live. The first great invention was one that is still very important today- the wheel. This made it easier to carry heavy things and to travel long distances.
For hundreds of years after that there were few inventions that had as much effect(影响) as the wheel. Then in the early 1800’s the world started to change. There was little unknown land left in the world. People didn’t have to explore(探测) much any more. They began to work instead to make life better.
In the second half of the 19th century many great inventions were made. Among them were the camera, the light and the radio. These all became a big part of our life today.
The first part of the 20th century saw more great inventions. The helicopter in 1909. Movies with sound in 1926. The computer in 1928. And jet planes in 1930. This was also a time when a new material was first made. Nylon came in 1935. It changed the kind of clothes people wear.
By this time most people had a very good life, Man has a desire to explore again, The world was known to man but the stars were not. Man began looking for ways to go into space. Russia made the first step. Then the United States took a step. Since then other countries, including China and Japan , have made their steps into space.
In 1969 man took his biggest step from the earth. Americans first walked on the moon. This is certainly just a beginning thought. New inventions will some day allow us to do things we have never yet dreamed of.
