初一数学老师国旗下讲话发言稿
成功者是需要坚韧的毅力和非凡的勇气的。一个人经历一些挫折并不是坏事情。“自古雄才多磨难，从来纨绔少伟男。”在我们成长的道路上，有坦途，也有坎坷;有鲜花，也有荆棘。在你伸手摘取美丽的鲜花时，荆棘同时会刺伤你的手。如果因为怕痛，就不愿伸手，那么对于这种人来说，再美丽的鲜花也是可望而不可及的。成功永远属于挑战失败的人。我们拥有年轻，年轻没有失败。只要能战胜荆棘，战胜自己，即便是弄行得遍体鳞伤，至少也可以证明我们曾经奋斗过，我们不是挫折的奴隶!
开学第一节思政课讲话稿
没有任何困难能够阻扰中国人前进的步伐。面对严重的疫情，“没有医院建医院”“没有床位加床位”。武汉火神山医院创造了速度的奇迹。有一组数据很能说明问题，也令人惊叹：5小时内拿出设计方案，不到24小时绘出设计图，最高峰时工地上有7000多名工人，800多台挖掘机、推土机等设备同时作业。可提供1600张床位的雷神山医院1月26日开工，2月8日交付使用。随即，武汉市13家方舱医院工程上马，并先后投入使用。很多国家几年都办不成的事，中国人8天就办成了，被世界称为“中国速度”，汇聚起中国力量!

人教部编版语文九年级上册综合性学习君子自强不息教案
正如朱敏先生所说的那样，他之所以能打败那些强大的对手是因为自己的一股韧劲。自强的心鞭策我们勇往直前，失败算什么，困难算什么，自强者永不止步。生命可以大写，也可以小写，还可以简写。小写的生命是灵魂上的侏儒，简写的生命是灵魂上的庸碌者，唯有自强者是天地间用正气、智慧写出的一个气宇轩昂的大写的人。独立是它的一撇，拼搏是它的一捺，两者缺少其一，都不能称之为一个完整意义上的“人”。自强是生命之杯中的琼浆玉液，他让每一个举杯者赢得了鲜花和掌声，收获了成功和喜悦，体味到了人生的真实与厚重!在我们的人生旅程中，每个人或多或少会遇到这样那样的挫折。也许是一次考试的失利，也许是一场突如其来的意外，没有谁能够保证他的一生总是平平安安、一帆风顺。面对挫折我们不应该失意、彷徨，因自己陷入人生灰色的圈子而倍感焦虑、难以自拔。我们要学会自强，因为只有学会自强，我们才敢正视所有问题；只有学会自强，才会有勇气去战胜一道道难题。

人教版高中政治必修4综合探究：坚持唯物辩证法，反对形而上学教案
5．循环经济当前，发展循环经济和知识经济已成为国际社会的两大趋势，有的发达国家甚至以立法的方式加以推进。循环经济本质上是一种生态经济，它要求运用生态学规律而不是机械的规律来指导人类社会的经济活动，减量化、再利用和资源化是其三大原则。传统经济是一种“资源——产品——污染排放”单向流动的线性经济，特征是高开采、低利用、高排放；与之不同，循环经济倡导的是一种与环境和谐的经济发展模式，它要求把经济活动组织成一个“资源——产品——再生资源”的反馈式流程，特征是低开采、高利用、低排放。目前，我国已经把发展循环经济作为编制“十一五”规划的重要指导原则。6．当心被优势“绊倒”有三个旅行者同时住进一家旅店，早上同时出门旅游。晚上归来时，拿伞的人淋得浑身是水，拿拐杖的人跌得满身是伤，而什么也没有带的人却安然无恙。
