A Black Monday for Virginia Tech. students...

This morning,I arrived my lab early.When I signed in my QQ,actually I had not signed in for a long time,and not long before I got a pop-up news snippet said that "American campus shooting causing 33 dead".This news of course is a big bang!So I launched my Web-browser to check this news out as soon as I can.Not surprisingly, this news hits the headlines of news site I know such as sohu,sina and CNN.From news report in CNN,Gunman massacres 33 at two Virginia Tech sites,Some students jumped from windows to escape,some Other students locked themselves in teacher's office.It is the deadliest shooting rampage in U.S. history.
