The computer

The computer was invented in 1946.At that time，it was huge and it was as large as a big house. It weighed about 30 tons. So it couldn’t be used widely.

But now the computer is small er and cheaper. It is a very useful tool in our life. We can use computer to send some messages to foreign friends by email. We can read news on the computer. We can also listen to music and play computer games on the computer. It makes us relaxed.

The computer is becoming more and more important in our daily life. In my opinion，it will change our life completely in the near future.
