下列是中国与美国、日本宪法有关国家制度的材料: 材料1 美国的“全部立法权,属于由参议院和众议院组成的合众国国会”。“行政权属于美利坚合众国总统”,“总统是合众国陆军、海军和应召为合众国服役的各州民兵的总司令”,“合众国的司法权,属于最高法院和国会不时规定和设立的低级法院”。“众议院和参议院通过的每一议案,在成为法律前应送交合众国总统。总统如批准方案,即应签署,如不批准,则应将议案连同其反对意见退回最初提出该议案的议院。该院应将谊项反对意见详细载入本院议事记录并进行复议。如经复议后,谊院三分之二议员同意通过该议案,该议案连同反对意见应一起送交另一议院,并同样由该院进行复议,如经该院三分之二议员赞同,该议案成为法律。” 摘自1887年美国宪法 材料2 “天皇是日本国的象征,是日本国民统一的象征,其地位,以主权所属的日本国民之意志为转移。”“天皇有关国事的一切行为,必须有内阁的建议与承认,由内阁负其责任”,“天皇根据国会的提名任命内阁总理大臣、最高法院法官”。“国会是最高国家权力机关,是国家惟一立法机关。”“行政属于内 阁”,“内阁总理大臣经国会议决在国会议员中提名”,“内阁总理大臣任命国务大臣”,“内阁在众议院通过不信任案或信任案被否决时,如十日内不解散,众议院必须总辞职。”“一切司法权属于最高法院及由法律规定设置的下级法院。” 摘自1946年日本宪法 材料3 “中华人民共和国的一切权力属于人民;人民行使国家权力的机关是全国人民代表大会和地方各级人民代表大会。”“全国人民代表大会是最高国家权力机关。”全国人民代表大会及其常委会“行使国家立法权”。“中华人民共和国的国家机构实行民主集中制的原则。”“国家行政机关、审判机关、检察机关都由人民代表大会产生,对它负责,受它监督。” 摘自1982年中国宪法 根据上述材料回答: (1)比较材料1、2,指出美国与日本政治制度的不同点和相同点。 (2)材料1、2所体现的资产阶级国家政权组织形式的实质及其作用。 (3)比较材料3与材料1、2,指出中国政治制度与美、日政治制度的不同及其根本原因。
