英国的政体是议会君主立宪制,国王是国家的最高元首,首相是政府的首脑,议会分为上院和下院.美国的政体是联邦共和制,所以其全名是“美利坚合众国”
Britain's system of government is parliamentary constitutional monarchy, the king is the supreme head of state, Prime Minister is the head of the Government, the Parliament is divided into the Upper House and Lower House. America's system of government is a federal republic, so his full name is "United States of America"
时政就免了吧
