请教下面bold部分啥意思？which 是说什么，the same指的之前哪个字，shall be 什么？如果是说“ in these states the places shall be for … 堡垒、弹药库etc. purpose”吗, 根本多余啊 To exercise exclusive Legislation in all Cases whatsoever, over such District (not exceeding ten Miles square) as may, by Cession of particular States, and the Acceptance of Congress, become the Seat of the Government of the United States, and to exercise like Authority over all Places purchased by the Consent of the Legislature of the State in which the Same shall be, for the Erection of Forts, Magazines, Arsenals, dock-Yards, and other needful Buildings;
In which the same shall be是指联邦国会对购买的州里的地方有exclusive立法权。这两句话都是确认联邦权力。 翻译：对於由某州让与而由国会承受，用以充当合众国政府所在地的地区 （不逾十哩见方） ，握有对其一切事务的全部专有立法权； 对於经州议会同意，向州政府购得，用以建筑要塞、弹药库、兵工厂、船坞和其它必要建筑物的地方，也握有同样的权力；

我觉得 to exercise like authority 已经是你说的意思了
