Anna and her CS class

When I first recognize that this semester I have to take CS class, my world is circumrotating. For other people it may be very easy, but not for me.
When I was young, I was really interested in computer ( though at that time computer was not notrifeness), so I was glad that I had my own computer at my 11th birthday. And then trouble came. I did't know what I do, but the computer would always be broken down within a week after I used it, or rather, not just computer, but every kind of application in my home. People always felt amazing with my special diathesis. So I had a second name "machine killer". For that reason, the best friends of my family are almost working in the computer company, three of five times they visit our home was helping me to repair my computer.In a word, I have a unbelievable poor sense of computer, and I will be cheerful if I pass the class smoothly and sucessfully.
