结合材料回答问题：
材料1
发展是快好还是慢好不可一概而论。有的快是擘画蓝图的神笔，有的快则是祸害的源起；有的慢是勤修内功的表现，有的慢则是不思进取的懈怠。发展可以快，但不能忽视了它的要素和内涵。低质量的发展，建不成现代化强国。不安全的发展，带不来人民福祉。不公平的发展，社会就会失去凝聚力。结构不合理的、低水平的发展，经不起市场的风浪、变幻的风云。不科学的发展，难以促进社会的和谐进步。无视这些基本道理，一味追求速度和规模，发展速度该降的不降，如同“沙雕”巨轮，外形好看，却试不得水，更承载不起东方大国的扬帆远航。
发展应当统筹兼顾资源和环境的承载力、社会和文化的整合力、人的心理和精神的承受力。自然资源大多取之有尽，用之而竭，吃了子孙的饭，把生态破坏了，把所得投进去也难再修复。把人们生存的环境污染了，生活质量就下降了。不注重社会整合，不注重文化培育，不注重人的精神调理，人们就会丧失生活的乐趣，降低幸福的指数。无视这些基本道理，无视科学发展的要求而一味追求速度，是难以实现现代化的。

材料3
由于加快转变经济发展方式是经济社会领域的一场深刻变革，需要打破对传统经济发展方式的“路径依赖”，所以，必须把深化改革作为加快转变的根本动力，用改革来促进和保障转变。还应看到，由于传统经济发展方式是由以往发展中各种体制、政策、方法、措施等综合构成的稳固模式，不仅仅是经济领域的问题，而是涉及经济社会活动各个领域、各个方面的复杂问题，因此，加快转变经济发展方式必须以更大决心和勇气全面推进各领域改革。正如“十二五”规划纲要强调的，要“坚定推进经济、政治、文化、社会等领域改革，加快构建有利于科学发展的体制机制”。只有这样，才能推动我国经济发展方式实现根本转变，实现科学发展。
