More than 6000 children were expelled(开除) from US schools last year for bringing guns and bombs to school, the US Department of Education said on May 8.
The department gave a report on the expulsions as saying handguns accounted for 58 percent of the 6093 expulsions in 1996—1997, against 7 percent for rifles(步枪) or shotguns and 35 percent for other types of firearms.
"The report is a clear sign that our nation’s public schools are cracking down(严惩)on students who bring guns to school", Education Secretary Richard Riey said in a statement, "We need to be tough-minded(坚强的) about keeping guns out of our schools and do everything to keep our children safe. "
In March 1997, an 11-year-old boy and a 13-year-old using handguns and rifles shot dead four children and a teacher at a school in Jonesboro, Arkansas. In October, two were killed and seven wounded in a shooting at a Mississippian school. Two months later, a 14-year-old boy killed three high school students and wounded five in Daducab, Kentucky.
"Most of the expulsions(开除), 56 percent, were from high schools, which have students from about age 13, 34 percent were from junior high schools and 9 percent were from elementary schools. " The report said.
