阅读下面的文字，完成下列小题。

    日前，全国各地精彩纷呈的科普日活动让人们享受了一顿顿“科普大餐”，虚拟现实等新技术让科普活动变得五彩斑斓、趣味十足。如果说科学知识是科普的“鱼”，那么科学精神、科学思维和科学的人文精神，就是科普的“渔”。我们常说，授人以鱼，不如授人以渔。近来的科普活动“鱼”多“渔”少，缺了些“精气神”。

    科学精神包括求实精神、创新精神等。求真是目标，创新是灵魂，这些宝贵的科学精神，不仅为科技创新提供良好的外围环境，同时也在约束科技团体的自身行为。而对普通人来讲，不管是做学问还是安身立命，这些精神都永不会过时。因为科学在追求知识和真理的同时，也赋予人崇高的理想，激励人们超越自我、追求更高的人生境界。

    科学思维在今天的科普内容中尤为重要，在一定程度上，甚至比普及科学前沿知识还要重要。现在，科学知识已经汗牛充栋，一般在网络上一搜就能找到，对普通民众来讲，除非个人极为感兴趣，否则并没有熟练掌握的必要。对大部分人来说，形成科学理性的反思能力，比掌握某种或某几种科学知识更为重要。比如，要让大众明白，科学是有局限性、阶段性的，包括医学在内的各种科学，都不是万能的。这样大众在面对一些诸如“量子矿泉水能治疗各种癌症”等骗局时，才能多一分清醒。

    科学的人文精神，和现在网上流行的“心灵鸡汤”大不一样，它以科学为基础和手段，以人文关怀为方向和目的，强调科学与人文相互协调和补充的思想，是唯物主义的人文观。在做科普时，也要让人们明白，科学与人文是人类文明飞升的双翼。科学技术是一把双刃剑，如何控制好这把利剑，有赖于人文精神的指导。

    总之，科学精神、科学思维和科学的人文精神，本身就是科学的一部分，是科学的“精气神”。在科普活动中，我们不能忽视对此的传播和普及，否则就会局限了科普的广度和深度。

    今天，我国大众科学素养依然和发达国家有较大差距，科学思维能力依然有待提高，有关科学理性和科学精神的教育依旧缺乏，这不能不说是一种遗憾。全国科普日活动已连续举办了十多年，在满足人们不断增长的科学需求方面发挥了重要作用。我们期待，随着这一活动的不断深化，科学的“精气神”能越来越足。
