Computer
Computers are becoming more and more important in our daily life. Do you know when the computer was invented The computer was invented in 1946. At that time, it was huge. With the development of science and technology, the computer has grown smaller. Now there are many kinds of computers, such as personal computers and laptops. The computer is a very useful tool in our life.
For example , it can send some messages to foreign friends by e-mail. What’s more, it can share information with others through the World Wide Web. We can also listen to music or play the game on computers. It makes us relax.
It’s hard to imagine what our life would be like without computers. I think computers will be more convenient and they are going to change our life completely in the near future.
