Some great inventions have made the world become a better place, especially those help people communicate more easily. Such inventions began in the 11th century, but they have developed greatly in the last century. Let’s take a look at the five top inventions.

Movable type (活字印刷术): By using Movable Type, books could be printed cheaply and easily. Bi Sheng invented Movable Type in China in the 11th century.

Telephone:The inventor Alexander Graham Bell made the first telephone call in 1876. “Mr. Watson, come here. I want to see you.” he said to his assistant (助手) over the phone line. And with those famous words, the world was about to get much smaller.

Airplane: The Wright brothers made the first powered flight in 1903. Air travel has made the far away places suddenly become a lot closer.

Satellites: The Soviet Union sent up the world’s first satellite in 1957. This began the Space Age. Satellites have helped scientists study the earth. Much of our knowledge of the world has come from the information recorded by satellites.

Internet: When the Internet was invented in 1969, only a few people knew about it. But more than 650 million people in the world use it now. The Internet has made information about anything easy to get.

Hi, everyone! My name is Lin Tao. I come from the capital (首都) of China, but this year I live in Changsha, Hunan.

Now I’m having lunch in a very special (特殊的) restaurant with my good friend from Zhengzhou, Henan. Do you want to know how special it is? In this restaurant, there are only two kitchen helpers. But every day there are over 800 people coming to eat in it. That’s because this restaurant has three robot cooks (机器人厨师). The robots can cook very quickly. People can get their food in five minutes.

Li Zhiming is the inventor(发明者) of the robot cooks and the boss (老板) of the restaurant. He is forty-five years old this year. He says, “In my city, such a big restaurant needs eight to ten cooks and kitchen helpers. But my restaurant is different. ”

Do you want to eat food made by robot cooks? Please come to this restaurant to have a try. I think you will like the food here. It is really delicious.

Computers are useful machines. They can help people a lot in their everyday life. For example, they can help people save much time, and they can help people work out many problems people can’t do easily.

Today more and more families own computers. Parents buy computers for their children. They hope computers can help them improve their studies in school. Yet many of the children use computers to play games, to watch videos or to sing songs, instead of studying. So many teachers and parents complain that computers can not help children study but make them fall behind. So computers are locked by parents in the boxes. In some other countries, even some scientists hate computers. They say computers make millions of people lose their jobs or bring them a lot of troubles.

Will computers really bring troubles to people or can they bring people happiness? It will be decided by people themselves.
