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.

This special pen was invented by Liu Jie. It has three colors and is used for taking notes quickly. It is very useful if you have a lot to write down. The pen comes with a microchip that can store a list of common words that you will use. You can program the words you will use often into the microchip’s memory, then assign a short form to each word.
When you are writing, you just need to write the short forms with the pen, press a button on the pen and all the short forms will change into the actual words. The microchip can contain up to 50 words and you can make changes to the list of words whenever you need to.
