Dear Tom,
How nice to hear from you again.
When father bought me a computer for a birthday present | 76． |
in last year, I felt very excited. As we all know, computers | 77． |
are getting more usefully nowadays. Much information | 78． |
can be stored in it. We can learn what has lately happened | 79． |
in the world on the Internet. People had to do lots of work | 80． |
which was very danger. Now, computers can do it instead. | 81． |
When an exam is come, I do exercises on my computer. | 82． |
Then it will correct them but tell me the right answers. | 83． |
It is convenient for me to prepare for the exam than | 84． |
before. The computer have become a real friend of mine. | 85． |
