查询词典 nickel

But the tragedies of Virginia Tech-and Columbine, and Nickel Mines, Pennsylvania, where five girls were shot at an Amish school last year-are not the full measure of the curse of guns. More bleakly terrible is America's annual harvest of gun deaths that are not mass murders :some 14,000 routine killings committed in 2005 with guns, to which must be added 16,000 suicides by firearm and 650 fatal accidents (2004 figures).

不过，枪支所带来的祸害，并不完全体现在弗吉尼亚理工大学及科隆布恩和宾夕法尼亚镍矿（去年5名女孩在一所教会学校遭枪杀）发生的悲剧上，更为触目惊心的是美国每年有很多人死于非大规模枪杀案--2005年大约有14000人死于枪击，此外还有16000人吞枪自尽以及650人因枪支走火不幸殒命（2004年统计数字）。
