纵观中国历史,清朝前期是封建社会的又一次太平盛世;横看世界历史,清朝前期又是一个不完美的盛世。阅读下列材料,完成相关问题。

材料一:在清兵入关的同时,英国的议会和国王之间在国王征税的权力问题上,发生了严重的冲突。议会民军在克伦威尔领导下,击败了皇家军队,而且以议会审判,判决将国王查理一世送上断头台……英国的这次革命,开启了新的国家体制。

材料二:它的设立与雍正初清廷向西北用兵有密切关系……它所承办的均为军国大政,且有人事咨询权……但是,它又只起承旨、草诏、代发的作用,类似皇帝的秘书班子。

材料四:清朝前期编纂了一批类书、政书、字典、律例、军事方略、诗文汇集……在《四库全书》编纂期间,凡是不利于清朝的,或是触犯了他们的忌讳的,都要加以删除和窜改,或是大量地进行销毁,甚至连宋代的书写到抗金的,明代的书写到抗元的,也遭到同样的厄运。

——孔立编《中国历史小丛书》

材料五:康、雍之世,政治还算清明,财政亦颇有余蓄。到乾隆时,虽然政治业已腐败,社会的元气,亦已暗中凋耗了,然表面上却还维持着一个盛况……清朝的衰机,可说是起于乾隆之世的。
