200多年前美国还属于英国殖民地时，美国人仅有向英国纳税的义务，而没有在英国议会中拥有议席、参加议政的权利。义务与权利的不平衡，是美国人奋起独立的根本原因。电视屏幕上或电影银幕上的美国警探片，经常会出现这样的镜头--警察给嫌疑人犯戴上手铐的同时，口中念念?.. When the United States also belonged to the British colony more than 200 years ago, Americans were only obliged to pay the British government tax. They did not have the right to attend seats in the British parliament and participate in the administration of state affairs. The imbalance between obligations and rights is the fundamental reason for the Americans to rise independently. American shotgun films on television screens or movie screens often show such shots - while the police handcuffed the suspects.
