The acidic gases such as SO2, NOx, H2S and CO2 are typical harmful pollutants and greenhouse gases in the atmosphere, which are also the main sources of PM2.5. The most widely used method of treating these gas molecules is to capture them with different adsorption materials, i.e., metal and nonmetallic materials such as MnO2, MoS2 and carbon-based materials. And doping transition metal atoms in adsorption materials are beneficial to the gas adsorption process. The first-principles calculation is a powerful tool for studying the adsorption properties of contaminant molecules on different materials at the molecular and atomic levels to understand surface adsorption reactions, adsorption reactivity, and structure-activity relationships which can provide theoretical guidance for laboratory researches and industrial applications. This review introduces the adsorption models and surface properties of these gas molecules on metal and nonmetallic surfaces by first-principles calculation in recent years. The purpose of this review is to provide the theoretical guidance for experimental research and industrial application, and to inspire scientists to benefit from first-principles calculation for applying similar methods in future work.

现在的你可能在大人眼中是个“小P孩”，可是你却相信自己已经长大了。你需要独立自主的生活，你想主宰自己的“小宇宙”，你想做自己想做的事情。现在的你反感别人为你安排一切，指挥你做这做那。可是现在的你是否能独立处理好自己的事情呢？ 有人说，独立性和自主性是衡量一个人是否心理成熟的标志之一，所以现在我们一起测试下，看你是能独立做主，还是依然有着依赖性！ 1.如果老师让你负责组织一场班级活动，你觉得自己

儿童，永远离不开群体。伙伴教育，是一种不可替代的教育形式和力量，父母和教师无法取代，先进的数码产品也不能替换。具备“相同密码”的孩子们在一起互相学习、为伴，可以快速提高他们的适应能力和交往能力。笔者结合多年的幼儿园工作经验，认为可从五个方面帮助幼儿获得伙伴教育。 一、自我介绍——留下美好印象 每学期开学初，我都会请班里的小朋友登台进行自我介绍，重点是在家长的指导下，跟全班的孩子介绍自己的性格、
