How to get siblings (兄弟姐妹) to get along

    One of the greatest gifts of parenthood is seeing your children form a relationship with each other that is independent of you. By giving hem someone else to play with, you can free up some time for yourself. Here are four techniques you can use to help your children appreciate each other while they're young.

    ⒊Activities and opportunities. Have your kids go to their siblings' games and activities____

    “My kids go to each other's activities, and take part in activities together,” says Patricia Walters-Fischer, mother of two. Not only do her children go, but they also offer support, encouraging each other before a big game or performance and offering comfort when things don't go well.

    ⒋Vacations. Don't ignore the value of a family vacation for bringing siblings together. When kids are away from their friends and forced to spend time together, they often enjoy each other____In fact, a weekend camping trip offers some of the best opportunities for working together, having fun and experiencing something new.

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。
