绪论三、辨析题:(判断正误,并说明理由)1、坚持马克思主义就是要完全、彻底地将马克思主义经典作家的理论贯彻下去,不容许一丝一毫的修改。
2、马克思主义具有阶级性,所以不是科学的。
四、判断题:(判断正误,正确的打“√”,错的打“×”)1、马克思主义是科学的世界观和方法论,学好它我们就能永不犯错误。
2、马克思恩格斯成为马克思主义理论的创立者,与他们个人的主观条件是分不开的。
3、与时俱进是马克思主义的理论品质,因此马克思恩格斯的思想已经过时了。
4、马克思主义是科学的体系,因此以马克思主义为指导的社会主义国家的发展总是一帆风顺的。
五、材料分析题:(阅读材料,分析并回答问题)材料1:马克思恩格斯在1872年为《共产党宣言》所写的序言中指出:不管最近25年来的情况发生了多大的变化,这个《宣言》中所阐述的一般原理整个说来直到现在还是完全正确的……由于最近25年来大工业有了巨大发展而工人阶级的政党组织也跟着发展起来,由于首先有了二月革命的实际经验而后来尤其是有了无产阶级第一次掌握政权达两月之久的巴黎公社的实际经验,所以这个纲领现在有些地方已经过时了。
特别是公社的经验已经证明:“工人阶级不能简单地掌握现成的国家机器,并运用它来达到自己的目的。
”——(《马克思恩格斯选集》(第1卷)1995年版)材料2:恩格斯在1895年时指出:历史表明我们也曾经错了,暴露出我们当时的看法只是一个幻想。
历史走得更远:它不仅打破了我们当时的错误看法,并且还完全改变了无产阶级借以进行斗争的条件。
1848年的斗争方法,今天在一切方面都已经过时了,这一点值得在这里比较仔细地加以探讨。
——(《马克思恩格斯选集》(第4卷)1995年版)材料3:“决不能要求马克思为解决他去世之后上百年,几百年所产生的问题提供现成答案。
列宁同样也不能承担为他去世以后五十年、一百年所产生的问题提供答案的任务。
真正的马克思列宁者必须根据现在的情况,认识、继承和发展马克思列宁主义。
