②④：中华人民共和国的成立，为实现由新民主主义向社会主义的过渡创造了前提条件，从根本上改变了中国社会的发展方向，为实现国家富强、民族复兴展示了美好前景和现实道路，②④表述错误。故本题选C。21.（12分)①辩证的否定具有肯定与否定的双重性，实质是扬弃。作为事物发展过程中的否定，是对旧事物整体、旧矛盾统一体的否定，从内打破即自己否定自己，自己发展自己，收获成长。②量变与质变的关系是辩证的，量变是质变的必要前提，质变是量变的必然结果，并为新的量变开辟道路。人生就是一个不断积累，最终实现质的飞跃的过程。③分析是综合的基础，综合是分析的先导。我们要学会在分析与综合的对立统一中面对人生的抉择，推动认识不断地发展。22.(7分)①量变是质变的必要前提，质变是量变的必然结果，体现并保存量变的成果，并为新的量变开辟道路。这要求我们以统一性的观念正确把握事物发展过程中的量变与质变、渐进性与飞跃性、连续性与间断性的关系。②我国巡天望远镜的建设，从提出到推进实施，是一个由量变到质变，又在新质基础上进行新的量变的不断循环的过程。23.(12分)①运用联想思维的想象方式。利用我国已有的文化器物，通过重新组合形成新的中国冬奥系列形象。②坚持发散思维和聚合思维相互结合，以彰显中华文化为目标，从不同角度提供创意设想，突出文化办奥的主题。③科学运用逆向思维。主火炬一改传统的点火方式，以“微火”取代熊熊大火，向世界传递了人与自然和谐相处的绿色奥运理念。24.(9分)①创新思维的思路具有多向性，从不同的方面、层次、条件构思多种设想。作品在创作中循着“展卷、问篆、唱丝、寻石、笔、淬墨、人画”的篇章纲目，探寻中国传统美学的意趣。②创新思维的步骤具有跨越性。作品有一点穿越剧的意思，呈现出神秘的色彩。
