參考範文：
As I am about to graduate and leave the campus, I am going to sell my personal laptop at a low price.
It is a Lenovo ThinkPad that I bought in June, 2015. It is not big, but very functional. It has a four-core CPU, an independent display card of 2G, a hard disk of 500G and a screen of 15.6 inches.
For the last two years, the laptop has served as my faithful aid and helped me finish most of my assignments and my thesis. There has appeared no fault in the process. I owe so much to it. But as my workplace has already offered me a more advanced working laptop, I find there is no necessity for me to have two. And I know that there must be some of my schoolmates who are more in need of the ThinkPad. Therefore, I determined to sell it.
I bought the laptop as the price of 3500 yuan. Now I will sell it at 1500 yuan or less. Anyone interested can contact me via email, and my mailbox is ***@sina.com.
