    A couple of weeks ago, a few friends and I had an opportunity to attend a dear friend's wedding in New York. After the wedding and reception, rather accidentally four of us gathered in a hotel room and began to explore the deeper meaning of life and death. What does it mean to live truly? If we are all getting closer to death, is all the material accumulation worth it? It is not exactly the type of conversations one has at a wedding.

    While the answers varied from person to person, I was left with more questions than answers and a feeling of gratefulness to be surrounded by friends who were asking the “right” questions. As the clock kept ticking past 3 a.m., one of the roommates suggested we watch a short film titled “Last Days of Zach Sobiech”. The film is about a teenager's journey through the last days of his incurable illness. The film brought up a lot of mixed emotions but one quote that stood out for me was Zach's simple explanation of happiness, “What makes one happy is seeing someone else smile because you put it there.” By 4 a.m. , there was this energy in the room that had to be shared! With a few packages of post-it notes, we hit the halls of the hotel. We decided to leave short inspirational words on guests' doors, so when they opened their doors few hours later a smile would turn up.

    We ended up sticking post-it notes on all the doors until we ran out of them. The note on the door of the newly-weds properly said, “Where there is love, there is life.”

创新是引领科技发展的第一动力,******强调:“科技是国家强盛之基,创新是民族进步之魂”。阅读材料,回答问题。

材料一:作为中部地区的区域中心城市,武汉的经济发展了,可水环境却承受着极大的压力。为此,2015年1月,武汉市政府印发了《武汉市中心城区排涝、治污、供水两年决战行动计划》,计划用2至3年实践,实施149个项目,投资140亿元,全力推进雨污水管网混错接改造和社区、高校、企事业单位内部雨污分流改造工作。为贯彻落实这一决策,武汉市各级政府、广大干部群众积极行动起来,一个全社会参与美丽江城建设的良好氛围正在逐步形成。

材料二:因为利用了最新的科技成果,转车方便、快捷、支付简单。加上惬意推广的补贴,优惠的价格吸引不少市民选择专车服务。目前,出租车行业主要依赖于政府限制运营数量,实施保护价格的措施来进行运营和管理。专车服务与出租车行业产生了强烈的利益冲突,因此在许多国家的扩张都受到了激烈反对。政府出于经济稳定和就业保障的目的,保护出租车行业的做法受到社会质疑,这种做法会损害消费者权益,容易滋生腐败现象。

材料三:由于转车“跑得太快”,法规“跟不上”,结果就出现了一个灰色地带,使政府对交通客运行业的管理变得困难。但转车服务的新模式,又能满足市场上高品质、多样化和差异化的出行需求。对此现状,中国交通运输部认为,不能对专车“一棍子打死”,要按照以人为本、鼓励创新、趋利避害、规范管理的原则进行管理。
