There have been many great inventions or things that changed the way we live. The first great invention was the one that is still very important today---the wheel. This made it easier to carry heavy things and to travel long distance.

For hundreds of years after that, there were few inventions that had as much effect as the wheel. Then in the early 1800s the world started to change. There was little unknown land left in the world. People didn’t have to explore 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 play a big part in our daily life today. The first part of the 20th century saw more great inventions. The helicopter(直升机) in 1909, movies with sound in 1926, the computer in 1928, jet planes(喷气式飞机) in 1930. This was also a time when a new material was first made. Nylon(尼龙) came out in 1935. It changed the kind of clothes people wore.

The middle part of the 20th century brought new ways to help people get over diseases. They worked very well. They made people healthier and allowed them to live longer. By the 1960s most people could expect to live to be at least 60.

By this time most people in developed countries had a very good life. Of course new inventions continued to be made. But man now had a desire(渴望) to explore again. The earth was known to man but the stars were not. Man began looking for ways to go into space. Russia made the first step. Then United States took a step. Since then other countries, including China and Japan, have made their own steps into space.

In 1969 man took his biggest step away from earth. Americans first walked on the moon. This is certainly just a beginning, though. New inventions will some day allow us to do things we have never yet dreamed of.

There are many inventions that have caused great changes in the world. Here is a short introduction of the maglev train (磁悬浮). The history of the maglev train started in the beginning of the 1900s. The American Robert Goddard and the French Emile Bachelet came up with the idea of frictionless (无摩擦的) trains. But scientist didn’t succeed in making it at that time.

About 60 years later, the Japanese started their research on maglev transportation. After many years of experiments, the Japanese began to build their first test line. 7 km in 1975, and finished it in 1977. Many test runs started in July, 1977 with a speed of 517 km/h. In 1990, Japan built the Yamanashi Maglev test line. This test line was 42.8 km long and the first running test was held in 1997.

The Germans also started research on the maglev train in the early 1970s. It took them ten years to make the first track(ti)model. In 1993, the longest nonstop test running was 1,674 km. That same year the speed reached 450km/h.

China finished a 30-km-long maglev train line in Shanghai in 2003. This is the first commercial (商业的) maglev train line in the world. Although this project cost over 1 billion dollars, we should feel proud of it.

3.The Germans spent ________ in making the first track model.

4.The Maglev train line in Shanghai is ________ long.
