Dear Principal，

Recently I have a lot of problems in the computer room of our school．Many students also had the same experience，so I am writing to tell you my opinions．

I think we should have new computers．The computers that we use at the moment are old and slow，and sometimes they don't work and are not connected to the Internet．Also，we need to buy new keyboards and mice because some letters on the keyboards are missing and many of the mice are not working properly．

Yesterday，for example，in my computer lesson I spent the whole class trying to work out a physics problem．I had to miss the ten-minute break for that．If the PC had a good keyboard，I would not have made so many mistakes．The keyboard had letters missing and the mouse wouldn't move the cursor around the screen properly．I tried other PCs but they were in worse condition．At last，when I was going to finish it，I had another problem—suddenly there was no electricity（電）!（    ）

The government says we should have more IT in all subjects and use IT in more lessons，so we really need to have new computers．

Ricky，

Class 6，Grade 9 student
