Because of the Wanna Cry, the computer center of the hospital shut down the Internet of our dormitory one month ago, made our so angrily! I called and asked the computer department whether the Internet would be recovered in days or not.The director answered me on the phone that it , in principal, would not be supplied to our again! My book which bought it from taobao net will arrive tomorrow and I need to download a software that the book shows to learners how to use for my study. Therefore, I go to our department to share its WIFI at night, but this is not convenient and waste a lot of time. I am always unhappy for that. It is hard to image that one can live without the Net!
