Unit4 InventionsGreat inventionsGreat inventions change the world. They help people live a better life. The following are three of the most important inventions in history. The wheel The wheel perhaps is the greatest invention in history. After its invention, traveling became faster and more comfortable. A few years ago, people started to use wheels on carriages. In the early19th century, the first trains began to carry passengers. At the start of 20th century, cars became popular. Without the wheel, we would not have these inventions. The telephone Alexander Graham Bell invented one of the first practical telephones in 1876. Since then, people have been able to speak to each other over long distances. Today millions of people across the world own mobile phones. They allow people to keep in touch with each other anytime, anywhere. The light bulb Thomas Edison developed the first practical light bulb in 1879. Before the invention of the light, people had to use oil lamps, gas lamps or candles to see at night. With light bulbs, people can do as many things in the evenings as they can in the daytime. Can you imagine living without them? 1. Change...into... 把……变成…… 2.

The ink also did not dry easily, and it sometimes made a mess on the paper. Biro wanted a better pen. His brother , George, helped him develop a special ink. The ink dried easily. Then they developed a new type of pen. There was a tiny ball at the tip of the pen. The ball rolled ink ont o the paper as it moved. They call it the “ ballpoint”pen. The ballpoint pen was a great success. Everyone love it. Now millions of people use it all over the world every day. People will always remember biro for his invention.

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.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 m have made their steps into space.In 1969 man took his biggest step from the earth.
